<p>I'm working on a time sheet application, where I'd like the user to be able to enter times in TextBoxes, e.g.: 8 a or 8:00 a or the like, just like you can in Excel.</p>
<p>Now if you enter a <em>date</em> in a TextBox and then use DateTime.TryParse, you can enter it in several formats (Jan 31, 2007; 1/31/2007; 31/1/2007; January 31, 2007; etc.) and .NET will figure it out and turn it into a DateTime.</p>
<p>But when I use DateTime.TryParse on a string like "8 a" or "8:00 a", it doesn't understand it.</p>
<p>I know I can use ParseExact, but I'm wondering if there's a more flexible solution. I want .NET to get 8:00a from "8 a" or "8:00 a", and to leave the date component at the default 1/1/0001.</p>

<p>We have encountered a very strange situation when we deployed an application at a customer site. This application is implemented as a service using C# on .NET 3. The application communicates with a web service that is written using gSOAP. In our .NET application, the classes that wrap the web service were created by performing "Add Service" in Visual Studio and referencing the WSDL. Communication is performed using HTTPS, but using port 35000.</p>
<p>What we are seeing is that when our application runs as "Local Administrator account" everything works well. However when our application runs as any other account, including "Local System account" and even a user account with network admin privileges, web service method calls sometimes time out. Other times they succeed but after a very, very long time, e.g. 100 seconds instead of less than 1 second as expected.</p>
<p>This customer is using Cisco switches in their network.</p>
<p>We have not encountered this behavior at other sites. Any insights or suggestions would be greatly appreciated.</p>

<p>What order of precedence are events handled in JavaScript?</p>
<p>Here are the events in alphabetical order...</p>
<ol>
<li>onabort - Loading of an image is
interrupted</li>
<li>onblur - An element loses focus</li>
<li>onchange - The user changes the
content of a field</li>
<li>onclick - Mouse clicks an object</li>
<li>ondblclick - Mouse double-clicks an
object</li>
<li>onerror - An error occurs when
loading a document or an image</li>
<li>onfocus - An element gets focus</li>
<li>onkeydown - A keyboard key is
pressed</li>
<li>onkeypress - A keyboard key is
pressed or held down</li>
<li>onkeyup - A keyboard key is
released</li>
<li>onload - A page or an image is
finished loading</li>
<li>onmousedown - A mouse button is
pressed</li>
<li>onmousemove - The mouse is moved</li>
<li>onmouseout - The mouse is moved off
an element</li>
<li>onmouseover - The mouse is moved
over an element</li>
<li>onmouseup - A mouse button is
released</li>
<li>onreset - The reset button is
clicked</li>
<li>onresize - A window or frame is
resized</li>
<li>onselect - Text is selected</li>
<li>onsubmit - The submit button is
clicked</li>
<li>onunload - The user exits the page</li>
</ol>
<p>What order are they handled out of the event queue?</p>
<p>The precedence is not first-in-first-out (FIFO) or so I believe.</p>

<p>I have multiple ordered lists. Unfortunately, the order of the items isn't a simple alpha or numeric comparison, otherwise this is trivial. So what I have is something like:</p>
<pre><code>List #1 List #2 List #3
groundhog groundhog easter
mothersday mayday mothersday
midsummer laborday halloween
christmas
</code></pre>
<p>And from this I can gather than groundhog < mothersday, but the relationship of groundhog and easter is unknown. I am guaranteed that the order of the items from list-to-list is self consistent. (i.e. that no matter which list it occurs in, easter is always before halloween)</p>
<p>But what I need is a new ordered list that represents each item in the other lists only once, that preserves all of the known relationships above:</p>
<pre><code>groundhog
easter
mayday
mothersday
midsummer
laborday
halloween
christmas
</code></pre>
<p>However, the following list is also perfectly valid:</p>
<pre><code>easter
groundhog
mothersday
mayday
midsummer
laborday
halloween
christmas
</code></pre>
<p>I'm looking for a fairly quick, general-purpose algorithm I can use to order N lists in this way. (Working C# code a plus, for sure, but not necessary.) </p>
<p>I have solution that works, but its O(N^2) and a dog with even modest data sets.</p>

<p>I have an htaccess file that uses mod_rewrite to redirect /controller to /index.php?controller=%controller%</p>
<p>Like this:</p>
<pre><code># Various rewrite rules.
<IfModule mod_rewrite.c>
RewriteEngine on
# Rewrite current-style URLs of the form 'index.php?controller=x&action=y'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?controller=$1 [L,QSA]
</IfModule>
</code></pre>
<p>Now, what I need to be able to do is make ONE of the controllers work with HTTP Authentication. I'm not asking if this is the best way to do things, I'm simply asking how to do it.</p>
<p>Example:</p>
<pre><code>http://www.example.com/ - It requires no auth
http://www.example.com/secret - requires auth
</code></pre>

<p>I'm working with an ASP.net 2.0 GridView control that is bound to the results of a sql query, so it looks something like this:</p>
<pre><code><asp:GridView ID="MySitesGridView" runat="server" AutoGenerateColumns="False" DataSourceID="InventoryDB" AllowSorting="True" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowCommand="GridView1_RowCommand" OnRowDataBound="siteRowDataBound">
<Columns>
<asp:BoundField DataField="Server" HeaderText="Server"/>
<asp:BoundField DataField="Customer" HeaderText="Customer" SortExpression="Customer" />
<asp:BoundField DataField="PublicIP" HeaderText="Site Address" DataFormatString="&lt;a href='http://{0}/foo'&gt;Go To Site&lt;/a&gt;" />
</Columns>
</asp:GridView>
</code></pre>
<p>As you can see, I'm displaying links with addresses in one of the columns (the one bound to the PublicIP field) using the format string:</p>
<pre><code>&lt;a href='http://{0}/foo'&gt;Go To Site&lt;/a&gt;
</code></pre>
<p>Here's the problem: I need to use one of the <em>other</em> columns from the result set as well as the PublicIP column in my links, but I don't know how to make that available to my format string. I essentially need that column bound to two columns from the result set. To clarify, I need something like:</p>
<pre><code>&lt;a href='http://{0}/{1}'&gt;Go To Site&lt;/a&gt;
</code></pre>
<p>Where {1} is the value of my other column. Is there any way to accomplish this cleanly (even if it doesn't use format strings)? I've looked into using TemplateFields as well, but can see no easy way to do it with them either.</p>

<p>In C# I sometimes wish I could make special methods for certain "instantiations" of generic classes.</p>
<p><strong>UPDATE: The following code is just a dumb example of a more abstract problem - don't focus too much on time series, just the principles of "adding extra methods" for certain T</strong>.</p>
<p>Example:</p>
<pre><code>class Timeseries<T>
{
...
TimeSeries<T> Slice(...) { ... }
}
</code></pre>
<p>In the case where T is double, I would like some extra methods, like <code>Integrate()</code>, <code>Interpolate()</code> and so on that make only sense for <code>double</code>, because I need to do arithmetic on them.</p>
<p>There are several ways to do this, but I cannot find one that I'm satisfied with.</p>
<p><strong>1. Inherit into a special class</strong></p>
<pre><code>class TimeseriesDouble : Timeseries<double>
{
double Interpolate(...) { ... }
...
}
</code></pre>
<p><strong>cons:</strong> <code>TimeseriesDouble.Slice()</code> will return a new <code>Timeseries<double></code> object, now missing my special methods.</p>
<p><strong>2. External methods</strong></p>
<pre><code>public static double Interpolate(Timeseries<double> ts, ...) { ... }
</code></pre>
<p><strong>cons:</strong> Breaks with OO principles. And I don't want to put my methods away. Also, the methods might need private/protected state.</p>
<p><strong>3. Extension methods</strong></p>
<p>Same as 2, just with a nicer calling syntax.</p>
<p><strong>4. Common base class</strong></p>
<pre><code>class TimeSeries_base { ... }
class TimeSeries<T> : TimeSeries_base { .. typesafe versions of methods .. }
class TimeSeriesDouble : TimeSeries_base { .. typesafe versions of methods .. }
</code></pre>
<p><strong>cons:</strong> too much duplication of things from <code>TimeSeries_base</code> into the two subclasses. The base class might become just a place holder for utility functions for the sub classes.</p>
<p><strong>pro:</strong> I can now do things like <code>List<TimeSeries_base></code> dynamically.</p>
<p><strong>5. Just forget about a common class</strong></p>
<p>I.e., keep <code>Timeseries<T></code> and <code>TimeseriesDouble</code> separate in the code.</p>
<p><strong>cons:</strong> Then I don't get all the benefit of treating a <code>TimeseriesDouble</code> like a <code>TimeSeries<T></code>, e.g. combining two timeseries with ZIP(A,B), where one happens to be of doubles.</p>
<hr>
<p><strong>Any other ideas?</strong>
Currently, I think I like the design (1) best.</p>

<p>Suppose I have a SELECT statement that returns some set of results. Is there some way I can number my results in the following way:</p>
<blockquote>
<p>SELECT TOP 3 Name FROM PuppyNames ORDER BY NumberOfVotes</p>
</blockquote>
<p>would give me...</p>
<blockquote>
<p>Fido</p>
<p>Rover</p>
<p>Freddy Krueger</p>
</blockquote>
<p>...but I want...</p>
<blockquote>
<p>1, Fido</p>
<p>2, Rover</p>
<p>3, Freddy Krueger</p>
</blockquote>
<p>where of course the commas signify that the numbers are in their own column. [I am using SQL Server 2000.]</p>

<p>There's been a cluster of Perl-hate on Stack Overflow lately, so I thought I'd bring my "<a href="http://use.perl.org/~brian_d_foy/journal/32556" rel="nofollow noreferrer">Five things you hate about your favorite language</a>" question to Stack Overflow. Take your favorite language and tell me five things you hate about it. Those might be things that just annoy you, admitted design flaws, recognized performance problems, or any other category. You just have to hate it, and it has to be your favorite language.</p>
<p>Don't compare it to another language, and don't talk about languages that you already hate. Don't talk about the things you like in your favorite language. I just want to hear the things that you hate but tolerate so you can use all of the other stuff, and I want to hear it about the language you wished other people would use.</p>
<p>I ask this whenever someone tries to push their favorite language on me, and sometimes as an interview question. If someone can't find five things to hate about his favorite tool, he doesn't know it well enough to either advocate it or pull in the big dollars using it. He hasn't used it in enough different situations to fully explore it. He's advocating it as a culture or religion, which means that if I don't choose his favorite technology, I'm wrong.</p>
<p>I don't care that much which language you use. Don't want to use a particular language? Then don't. You go through due diligence to make an informed choice and still don't use it? Fine. Sometimes the right answer is "You have a strong programming team with good practices and a lot of experience in Bar. Changing to Foo would be stupid."</p>
<hr />
<p>This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.</p>
<p>Hate isn't the only dimension of figuring out how much people know, but I've found it to be a pretty good one. The things that they hate also give me a clue how well they are thinking about the subject.</p>

<p>Background: we have a system that was written in an older CMS based on Java back during the 2002-2003 days. We want to keep moving forward with our new stuff, using tomcat, stripes, and sitemesh. We have navigation, layouts, "pods", js, css, etc, that we've taken out of the old CMS and into a few of our new apps so we have consistent look and feel.</p>
<p>We now need some sort of solution to get rid of all the code duplication going on. Our apps are running on the same VM at the moment, but that might change. We need a way for all of our tomcat instances to access some common elements (and those elements may/may not need to do some server side stuff). </p>
<p>The best we've come up with so far is making a fairly standard sitemesh decorator, that uses c:import to get what it needs, and plugs it right in. This solution has some network overhead which could bog it down and introduce a fail point. We've looked at <%@ include file="/something.jsp" %> as well but that seems to be only context relative. We could use c:import and point it at localhost, which seems to be the best solution so far. </p>
<p>Are there other templating/decorating frameworks out there (Tiles?) that could make this simpler? What are we missing?</p>

<p>I run a series of time consuming operations on a background worker thread. At various stages I update a (windows form) progress bar by invoking a delegate. However, one of the more time operations occurs on a single line of code.</p>
<p>Is it possible to :</p>
<p>a) Update the UI while that single line of code is being executed, or at least display an animated icon that shows the user that work is being done.</p>
<p>b) Let the user cancel the background worker thread while that single line of code is being executed</p>

<p>Recently I had to move one of my web applications to a new hosting provider. The mail and web service is still held on the old hosting site however, when I try to send an email from the new server,I get an error; </p>
<p>"The server rejected one or more recipient addresses. The server response was:</p>
<pre><code>450 <email_address>: Recipient address rejected: Greylisted for 5 minutes
</code></pre>
<p>I asked my old hosting provider what I need to do to fix this and they replied with</p>
<blockquote>
<p>The mail server operates on POP before
SMTP. If a valid POP login is not
received before sending mail through
the server, then the mail is
greylisted and held for 5 minutes
before a retry. </p>
<p>To prevent this, simply do a Receive
before sending mail</p>
</blockquote>
<p>Does anyone have any idea how I do a POP before SMTP in C#? </p>

<p>want to pass boost::bind to a method expecting a plain function pointer (same signature).</p>
<pre><code>typedef void TriggerProc_type(Variable*,void*);
void InitVariable(TriggerProc_type *proc);
boost::function<void (Variable*, void*)> triggerProc ...
InitVariable(triggerProc);
error C2664: 'InitVariable' : cannot convert parameter 1 from
'boost::function<Signature>' to 'void (__cdecl *)(type *,void *)'
</code></pre>
<p>I can avoid storing a boost::function and just pass the bound functor directly, but then I get similar error:</p>
<pre><code>error C2664: 'blah(void (__cdecl *)(type *,void *))' : cannot convert parameter
1 from 'boost::_bi::bind_t<R,F,L>' to 'void (__cdecl *)(type *,void *)'

<p>In Visual Studio, How do I show all classes inherited from a base class? </p>
<p><strong>For example</strong>, in ASP.NET MVC there are several '<a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.actionresult.aspx" rel="noreferrer">ActionResult</a>' types -- and they all inherit from / implement the base class <code>ActionResult</code>. </p>
<p>It looks like unless you just 'know' that <code>View</code> and <code>Json</code> are valid <code>ActionResult</code> types, there is no way you can easily find this information out. </p>
<p><em>Please prove me wrong.</em></p>
<p>Is there something in the object browser that makes this easy to find out?</p>
<p>I'm even up for suggestions of tools outside of Visual Studio to discover this information about various classes. For example: is there something in Resharper that will help me out?</p>

<p>.NET 3.5, C#</p>
<p>I have a web app with a "search" feature. Some of the fields that are searchable are first-class columns in the table, but some of them are in fact nested fields inside an XML data type. </p>
<p>Previously, I built a system for dynamically constructing the SQL for my search. I had a nice class hierarchy that built SQL expressions and conditional statements. The only problem was it was not safe from SQL injection attacks.</p>
<p>I was reading <a href="http://blog.wekeroad.com/2008/02/27/creating-in-queries-with-linq-to-sql/" rel="nofollow noreferrer">Rob Conery's excellent article</a> which pointed out that multiple queries can combined into a single TSQL query for the server if the IQueryable result is never enumerated. This got me to thinking that my dynamic search construction was much too complicated - I just needed to combine multiple LINQ expressions.</p>
<p>For example (contrived):</p>
<pre><code>Author:
ID (int),
LastName (varchar(32)),
FirstName (varchar(32))
context.Author.Where(xx => xx.LastName == "Smith").Where(xx => xx.FirstName == "John")
</code></pre>
<p>Results in the following query:</p>
<pre><code>SELECT [t0].[ID], [t0].[LastName], [t0].[FirstName]
FROM [dbo].[Author] AS [t0]
WHERE ([t0].[LastName] = Smith) AND ([t0].[FirstName] = John)
</code></pre>
<p>I realized this might be the perfect solution for a simple dynamic query generation that's safe from SQL injection - I'd just loop over my IQueryable result and execute additional conditionals expressions to get my final single-execution expression.</p>
<p>However, I can't find any support for evaluation of XML data. In TSQL, to get a value from an XML node, we would do something like</p>
<pre><code>XMLField.value('(*:Root/*:CreatedAt)[1]', 'datetime') = getdate()
</code></pre>
<p>But I can't find the LINQ to SQL equivalent of creating this evaluation. Does one exist? I know I can evaluate all non-XML conditions DB side, and then do my XML evaluations code side, but my data are large enough that A) that's a lot of network traffic to drag on performance and B) I'll get out-of-memory exceptions if I can't evaluate the XML first DB side to exclude certain result sets.</p>
<p>Ideas? Suggestions? </p>
<p>Bonus question - If XML evaluation is in fact possible DB side, what about FLWOR support?</p>

<p>I am just getting started with IoC containers so apologies if this is a stupid question.</p>
<p>I have code like the following in an app</p>
<pre><code>internal static class StaticDataHandlerFactory
{
public static IStaticDataHandler CreateHandler(StaticDataUpdate staticDataUpdate)
{
if (staticDataUpdate.Item is StaticDataUpdateOffice)
{
return new OfficeUpdateHandler();
}
if (staticDataUpdate.Item is StaticDataUpdateEmployee)
{
return new EmployeeUpdateHandler();
}
if (staticDataUpdate.Item == null)
{
throw new NotImplementedException(
string.Format("No static data provided"));
}
else
{
throw new NotImplementedException(
string.Format("Unimplemented static data type of {0}", staticDataUpdate.Item.GetType().FullName));
}
}
}
</code></pre>
<p>It is basically a simple factory that returns the correct strategy for handling the input data.</p>
<p>Would an IoC container allow me to eliminate code like this? That is to say : would it allow me to dynamically choose a concrete implementation to load based on the type of an input parameter?</p>
<p>Or am I way off course here?</p>

<p>I have a Flash application that is hosted from within a Drupal page. Some parts of the Flash application should be available to all users, but some should only be available to a logged-in user. (The specific role doesn't matter, just that they are any authorized user of the site).</p>
<p>From within Flash, I can detect whether the user is logged on by screen-scraping the "?q=user" page, but this is very brittle. What is the "right" way to do this? I can install additional Modules if necessary, but they need to be compatible with Drupal 6, not 5.</p>
<p>Similarly, if there is no user currently logged in, how can I take a username and password that they provide to me and log them in (or determine that the password is bad)?</p>

<p>I'm developing a SOAP application that integrates with a 3rd party. I think the WSDL of this third party is very strange. I'm pretty new to SOAP, so I don't want to go asking them to fix it if it isn't broken. Here's some things I've noticed that I consider wrong about it, though I'm sure it's technically a valid document (hence the reason I wrote "best practices" in the title). Also, I'm using gSOAP as my SOAP library, which may be why I think some of these things are weird (I'm even newer to gSOAP than I am to SOAP in general).</p>
<ol>
<li><p>they have interfaces specified for both SOAP 1.1 and SOAP 1.2 in the same WSDL. This causes gSOAP to generate twice as many classes as it needs to, since I'm only going to use 1.2.</p></li>
<li><p>all of their namespaces are <code>http://tempuri.org</code>. That shouldn't be like that, right?</p></li>
<li><p>despite defining a bunch of RPC calls, their WSDL uses the document format. I'm thinking of asking them to switch to RPC format because it seems that gSOAP won't generate methods that take C++ typed parameters for document format. Instead, it creates a new class for every API function's input and response data. I'll have to write another layer of wrapping around the gSOAP stuff to provide a reasonable API to the rest of my app if I can't fix that. Also, AFAICT, the XML that will be going back and forth would be exactly the same as it is now if they switched to RPC, so I don't think it would be difficult.</p></li>
<li><p>elements have minOccurs = 0 yet when I submit requests without them, I get errors returned back indicating they're required (sometimes even stack traces of null pointer exceptions). They should specify them as minOccurs = 1 if they're required, right?</p></li>
<li><p>nearly all of the web service functions specify a response that includes an integer to indicate success (really a boolean) and an error message string. Should they be using SOAP faults for this? I think it would be easier for my application to handle if it was a fault since gSOAP will let me figure that out really easily (and print the error message trivially).</p></li>
</ol>
<p>Of course, I don't have high hopes that this 3rd party company will change their WSDL just because I've asked them to. At least I'll learn something... for all I know, none of these are wrong or even questionable. Thanks for your help.</p>

<p>I have a .net transaction with a SQL insert to a SQL Server 2005 database. The table has an identity primary key. </p>
<p>When an error occurs within the transaction, <code>Rollback()</code> is called. The row inserts are rolled back correctly, however the next time I insert data to the table, the identity is incremented as if the rollback never occurred. So essentially there are gaps in the identity sequence. Is there any way to have the <code>Rollback()</code> method reclaim the missing identity? </p>
<p>Am I not approaching this the right way?</p>

<p>I am working on a small project to take a CSV file and then insert its data into a HTML table (I would use datagrid and dataset or datatable, but the system I will be talking to does not support ASP.NET uploads for sending newsletters).</p>
<p>Anyway, I will use the file.readalllines method to return the contents of the csv file into a string array.</p>
<p>But for each string member of the array, I will be using the string.split function to split up the string into the char array. Problem is (and the csv file is generated by the system I talk to btw - I get data from this system and feed data into it), the csv contents are makes of cars. This means that I could have:</p>
<p>Nissan Almera</p>
<p>Nissan Almera 1.4 TDi</p>
<p>VW Golf 1.9 SE</p>
<p>And so forth...</p>
<p>Is there a robust way I could ensure that where I have Almera 1.4 TDi, for example, it is one member in the char array I split each string into, rather than seperate members.</p>

<p>How can I determine current version of my repository to see if I need to upgrade it (svnadmin upgrade)?</p>
<p>In reality I'm hosting SVN with 3rd party and I want to find out if I need to ask them to upgrade my repos or not.</p>
<p>I'm asking since 1.5 server will keep repo version at 1.4, unless I miss something?</p>

<p>The following C# code takes 5 minutes to run:</p>
<pre><code>int i = 1;
string fraction = "";
while (fraction.Length < 1000000)
{
fraction += i.ToString();
i++;
}
</code></pre>
<p>"Optimising it" like this causes it to run in 1.5 seconds:</p>
<pre><code>int i = 1;
string fraction = "";
while (fraction.Length < 1000000)
{
// concatenating strings is much faster for small strings
string tmp = "";
for (int j = 0; j < 1000; j++)
{
tmp += i.ToString();
i++;
}
fraction += tmp;
}
</code></pre>
<p><strong>EDIT:</strong> Some people suggested using <code>StringBuilder</code>, which is an excellent suggestion also, and this comes out at 0.06s:</p>
<pre><code>int i = 1;
StringBuilder fraction = new StringBuilder();
while (fraction.Length < 1000000)
{
fraction.Append(i);
i++;
}
</code></pre>
<p>Playing around to find the optimum value of <code>j</code> is a topic for another time, but why exactly does this non-obvious optimisation work so well? Also, on a related topic, I've heard it said that you should never use the <code>+</code> operator with strings, in favour of <code>string.Format()</code>, is this true?</p>

<p>Consider the following trivial HTML page that throws an error:</p>
<pre><code><html><head><script>
throw new Error('oops');
alert('should not reach here');
</script></head></html>
</code></pre>
<p>The user I am logged into Vista with is a member of both the Administrators and Debugger Users groups.</p>
<p>If I run Internet Explorer on Vista as an administrator (right click → <strong>Run as administrator</strong>) and load the page I get the following error prompt:</p>
<p><a href="https://i.stack.imgur.com/pIdR1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pIdR1.png" alt="alt text"></a></p>
<p>Clicking Yes displays the following prompt from which I can successfully open Visual Studio 2008 and debug the problem:</p>
<p><a href="http://img227.imageshack.us/img227/9751/debuguy3.png" rel="nofollow noreferrer">alt text http://img227.imageshack.us/img227/9751/debuguy3.png</a></p>
<p>If I instead launch Internet Explorer normally and load the page no error prompt is displayed (or any indication of the error for that matter) and I can't jump in and debug the problem.</p>
<p>I've tried making the site the page is served from a trusted site in Internet Explorer. This causes the error prompt to be displayed for the page, but clicking yes doesn't do anything and the browser just sits and hangs.</p>
<p>Similarly I can only successfully attach to an existing Internet Explorer process from Visual Studio to debug JavaScript if Internet Explorer was run as an administrator.</p>
<p><strong>How can I successfully debug JavaScript with Visual Studio when running Internet Explorer with UAC enabled?</strong></p>

<p>What is a good way to set up a single container div with some border images surrounding it (in my case only on the left, bottom, and right sides)? I have it centered at the top of the page, overlapping everything else (so like that OSX-style slide-down dialog).</p>
<p>Here's the basic layout:</p>
<p><img src="https://i.stack.imgur.com/HoGAj.jpg" alt="alt text"></p>
<p>Here's what I've got so far (can I avoid a static width/height for the content?):</p>
<p><strong>HTML:</strong></p>
<pre><code><div class="contentbox">
<div class="contentbox-wrapper" style="width: 400px">
<div class="contentbox-mid" style="height: 200px">
<div class="contentbox-w"></div>
<div class="contentbox-content">
Content Box Test
</div>
<div class="contentbox-e"></div>
</div>
<div class="contentbox-bottom">
<div class="contentbox-sw"></div>
<div class="contentbox-s"></div>
<div class="contentbox-se"></div>
</div>
</div>
</div>
</code></pre>
<p><strong>CSS:</strong></p>
<pre><code>.contentbox {
width: 100%;
position: fixed;
z-index: 2;
}
.contentbox-wrapper {
width: 300px;
margin-left: auto;
margin-right: auto;
}
.contentbox-mid {
height: 100px;
}
.contentbox-w {
width: 30px;
height: 100%;
background: transparent url("../../images/contentbox_w.png");
float: left;
}
.contentbox-content {
width: auto;
height: 100%;
background: #e8e8e8;
float: left;
}
.contentbox-e {
width: 30px;
height: 100%;
background: transparent url("../../images/contentbox_e.png");
float: left;
}
.contentbox-bottom {
width: 300px;
height: 30px;
}
.contentbox-sw {
width: 30px;
height: 30px;
background: transparent url("../../images/contentbox_sw.png");
float: left;
}
.contentbox-s {
height: 30px;
background: transparent url("../../images/contentbox_s.png");
margin-left: 30px;
margin-right: 30px;
}
.contentbox-se {
width: 30px;
height: 30px;
background: transparent url("../../images/contentbox_se.png");
float: right;
position: relative;
bottom: 30px;
}

<p>Does this pattern:</p>

</code></pre>
<p>Actually return control to the UI from within a loop? When are you supposed to use it? Does it work equally well in all browsers?</p>

<p>The <code>PropertyGrid</code> control is very useful for editing objects at run-time. I'm using it as follows:</p>
<pre><code>Form form = new Form();
form.Parent = this;
form.Text = "Editing MyMemberVariable";
PropertyGrid p = new PropertyGrid();
p.Parent = form;
p.Dock = DockStyle.Fill;
p.SelectedObject = _MyMemberVariable;
p.PropertyValueChanged += delegate(object s, PropertyValueChangedEventArgs args)
{
_MyMemberVariable.Invalidate();
};
form.Show();
</code></pre>
<p>As you can see, I'm using the <code>PropertyValueChanged</code> notification to figure out when to update <code>_MyMemberVariable</code>. However, <code>_MyMemberVariable</code> is a class that I didn't write, and one of its members is a <code>Collection</code> type. The <code>PropertyGrid</code> calls the Collection Editor to edit this type. However, when the Collection Editor is closed, I do not get a <code>PropertyValueChanged</code> notification.</p>
<p>Obviously, I could work around this problem by using <code>ShowDialog()</code> and invalidating <code>_MyMemberVariable</code> after the dialog is closed. </p>
<p>But I'd like to actually get <code>PropertyValueChanged</code> events to fire when collections have been edited. Is there a way to do that without modifying <code>_MyMemberVariable</code> (I don't have access to its source code)? </p>

<p>I've noticed, using visual studio 2003, that I can "comment out" my comments to make them no longer be comments. This one needs an example:</p>
<p>If I have:</p>
<pre><code>/*
int commented_out = 0;
*/
</code></pre>
<p>I can comment out the /* and */ with // and code within the /* and */ is no longer "commented out" (the text changes to non-comment color <strong>and</strong> the compiler treats it as code once again). Like so:</p>
<pre><code>///*
int commented_out = 0;
//*/
</code></pre>
<p>I've found this is true for msvc 2003, is this normal C++ behavior or is it just a fluke that works with this compiler?</p>

<p>I'm looking for a .NET library that will allow creation of a Word document. I need to export HTML based content to a Word doc (97-2003 format, not docx).</p>
<p>I know that there are the Microsoft Office Automation libraries and Office interop, but as far as I can tell, they require that you have office actually installed and they do the conversion by opening word itself. But I don't want to have the requirement of having office installed for the conversion to work.</p>
<p>Edit: Converting to RTF may even work, if possible.</p>

<p>I was wondering if there is a way to implement an action listener for a Jbutton without a name. For example, I have the following for loop that creates a button for each letter of the alphabet.</p>
<pre><code>for (int i = 65; i < 91; i++){
alphabetPanel.add(new JButton("<html><center>" + (char)i));
}
</code></pre>
<p>Is there a way that I can add an action listener for each of those buttons without getting rid of my for loop and hard coding each JButton and then creating an action listener for each? </p>
<p>Thanks in advance,</p>

<p>I'm writing my first Windows CE app using the .NET Compact Framework v3.5.<br>
I need the app to be able to do an HTTP POST to a URL.<br>
It appears that the .NET CF does not have System.Web.<br>
So, I could use some guidence on how to accomplish and HTTP Posts using the .Net CF.
Thanks,
Greg</p>

<p>Simple question, hopefully an easy way and just want to verify I'm doing it the correct / efficient way.</p>
<p>I have a class T object, which is typically put into a vector that is created in my main() function. It can be any kind of data, string, int, float.. etc. I'm reading from a file... which is inputted from the user and passed onto the function. Here is my basic read in function:</p>
<pre><code>template <class T, class U>
void get_list(vector<T>& v, const char *inputFile, U)
{
ifstream myFile;
T object;
myFile.open("inputFile")
while(!myFile.eof())
{
myFile >> object;
insert(v, object, U)
}
}
</code></pre>
<p>insert is just another function that will go through and insert the data into my data structure. I just want to make sure this is the best way to pass that data on if it will even work.</p>

<p>I'm trying to design a homepage for an MVC site that has two different views, based on if the user is logged in or not.</p>
<p>So image the default (not logged in) view is showing general, nonspecific info. If i'm logged in, the view is showing mostly personal stuff instead.</p>
<p>What's the best practice to handling this? Don't forget, we also need to unit test this.</p>
<p>Thanks heaps!</p>

<p>I have a system which sits on a web server and generates files on the fly in response to HTTP requests. This is currently implemented as an HTTPHandler.</p>
<p>Once the files are generated, they don't change very often, so I'd like to implement a cache.</p>
<p>Ideally, I'd like the web server to look at the cache folder and serve the files directly from there without <strong>any</strong> of my code having to execute (web servers are designed to be good at serving files after all, so if I can keep out of the way of that so much the better!).</p>
<p>What I'd like to then do is hook into the server's "file not found" event as an opportunity to create the file, drop a copy in the cache folder for the next time it's requested and also return it to the user instead of the "file not found" message.</p>
<p>This way, repeat requests for files will be lightening fast and my code will only get called in 'exceptional' cases.</p>
<p>So - the question is - how do I wire my code into the "file not found" event in as unobtrusive and lightweight way as possible?</p>
<p>Thanks</p>

<p>For large <code>n</code> (see below for how to determine what's large enough), it's safe to treat, by the central limit theorem, the distribution of the sample mean as normal (gaussian) but I'd like a procedure that gives a confidence interval for any <code>n</code>. The way to do that is to use a Student T distribution with <code>n-1</code> degrees of freedom.</p>
<p>So the question is, given a stream of data points that you collect or encounter one at a time, how do you compute a <code>c</code> (eg, <code>c=.95</code>) confidence interval on the mean of the data points (without storing all of the previously encountered data)?</p>
<p>Another way to ask this is: How do you keep track of the first and second moments for a stream of data without storing the whole stream?</p>
<p>BONUS QUESTION: Can you keep track of higher moments without storing the whole stream?</p>

<p>I'm using a logging module that can have reporting enabled/disabled at runtime. Calls generally go something like:</p>
<pre><code>WARN(
"Danger Will Robinson! There are "
+ boost::lexical_cast<string>(minutes)
+ " minutes of oxygen left!"
);
</code></pre>
<p>I'm using an inline function for WARN, but I'm curious as to how much optimization is going on behind the scenes -- evaluation of the arguments throughout the entire program would be costly. The <code>WARN</code> function goes something like this:</p>
<pre><code>bool WARNINGS_ENABLED = false;
inline void WARN(const string &message) {
if (!WARNINGS_ENABLED) {
return;
}
// ...
}
</code></pre>
<p>Given that constructing the string argument has no side-effects, will the compiler optimize it out? Is a certain level of optimization required (<code>-Ox</code> in <code>g++</code> for some <code>x</code>)?</p>

<p>I'm a new to MSBuild and wanted to play around with it a bit, but I just cannot figure out why this isn't working.</p>
<p>So my solution has two projects: "Model" and "BuildTasks". BuildTasks just has a single class:</p>
<pre><code>using Microsoft.Build.Utilities;
namespace BuildTasks
{
public class Test : Task
{
public override bool Execute()
{
Log.LogMessage( "FASDfasdf" );
return true;
}
}
}
</code></pre>
<p>And then in the Model.csproj I've added this:</p>
<pre><code> <UsingTask TaskName="BuildTasks.Test" AssemblyFile="$(SolutionDir)src\BuildTasks\bin\BuildTasks.dll" />
<Target Name="AfterBuild">
<Test />
</Target>
</code></pre>
<p>I've set up the build order so "BuildTasks" gets built before "Model". But when I try to build Model I get this error:</p>
<blockquote>
<p>The "BuildTasks.Test" task could not
be loaded from the assembly
C:\WIP\TestSolution\src\BuildTasks\bin\BuildTasks.dll.
Could not load file or assembly
'file:///C:\WIP\TestSolution\src\BuildTasks\bin\BuildTasks.dll'
or one of its dependencies. The system
cannot find the file specified.
Confirm that the <UsingTask>
declaration is correct, and that the
assembly and all its dependencies are
available.</p>
</blockquote>
<p>This file definitely exists, so why can't MSBuild find it?</p>
<p>I've even tried hard-coding "C:\WIP\TestSolution" in place of "$(SolutionDir)" and get the same error. However, if I copy that .dll to my desktop and hard-code the path to my desktop, it <em>DOES</em> work, which I can't figure out why.</p>
<p><strong>EDIT</strong>: I don't have the path wrong. I modified the Debug/Release builds for BuildTasks to output the .dll to just the bin folder since I didn't want Debug/Release to have different paths.</p>

<p>We have a My_list class that has a list of pointers to Abstract_things. To optimize on memory usage, all derived Things use one memory pool that is established with the "new and delete" stereotype. In order to size the pool properly during the initization of the application, the builder figures out which Thing is the biggest and sizes the pool based on that. </p>
<p>The design dilemma is that if a new Thing is added to the model, (represented with the red Thing_4), the designer has to know to go over to Builder to adjust the logic. I have observed that it was hard enough for our team to remember to do this (about half our Things weren’t considered in the Builder). I’m very concerned that future generations will overlook this.</p>
<p>My question is how can I improve this? It would be wonderful if in the act of creating a Thing_4 class, all that max_size stuff automagically got handled. I can’t think of a way though.</p>
<p>Note: Reviewing my picture I realize there's a mistake. The last line in the code-box should read Abstract_thing::set_max_pool_size(max_size, max_number).</p>
<p>Edit: I can't figure out how to display a picture. Everything looks good in the preview window, but when published it's not there. Any help?</p>
<p>Edit: To give a little bit more background, this is part of a design for an embedded application in a safety-critical system. We are allowed to allocate memory off the heap when the application is initializing, but after we exit that initialization phase, NO dynamic memory can be allocated. Attempting to do so crashes the application. Therefore, we program to the largest sizes and the maximum number of instances we use. Having one pool that contains enough space for all derived objects is the better approach over having a pool for each derived object.</p>

<p>It seems that everybody knows you're supposed to have a clear distinction between the GUI, the business logic, and the data access. I recently talked to a programmer who bragged about always having a clean data access layer. I looked at this code, and it turns out his data access layer is just a small class wrapping a few SQL methods (like ExecuteNonQuery and ExecuteReader). It turns out that in his ASP.NET code behind pages, he has tons of SQL hard coded into the page_load and other events. But he swears he's using a data access layer.</p>
<p>So, I throw the question out. How would you define a data access layer?</p>

<p>I'm attempting to utilize <a href="http://en.wikipedia.org/wiki/VBScript" rel="nofollow noreferrer">VBScript</a> to connect pull the <code>physicalDeliveryOfficeName</code> attribute in <a href="http://en.wikipedia.org/wiki/Active_Directory" rel="nofollow noreferrer">Active Directory</a> by providing the email address. </p>
<p>I know how to do it with a common name like the following:</p>
<pre><code>Set MyUser = GetObject ("LDAP://cn=" & uname & ",ou=" & strname & ",DC=bobdom,DC=net")
</code></pre>
<p>However only the email address is available. How to do this? I've even tried </p>
<pre><code>Set MyUser = GetObject ("LDAP://mail=" & uname & ",ou=" & strname & ",DC=bobdom,DC=net")
</code></pre>
<p>and that doesn't work. </p>

<p>What is the correct way to convert ASP.NET SOAP-based web services to JSON-based responses?
...And then call these from jQuery?</p>
<p>What are "best practices" when integrating jQuery based AJAX and ASP.NET?
Articles? Books?</p>

<p>In PHP, I can write:</p>
<pre><code>$vname = 'phone';
$$vname = '555-1234';
print $phone;
</code></pre>
<p>... And the script will output "555-1234".</p>
<p>Is there any equivalent in Perl?</p>
<p>Is there any way to constrain <code>$phone</code> to the scope of the local block, as if I'd written <code>my $phone</code>? Using <code>my $$vname</code> gives me "Can't declare scalar dereference in my at ..." errors.</p>

<p>Something that confuses me, but has never caused any problems... the recommended way to dispatch an event is as follows:</p>
<pre><code>public event EventHandler SomeEvent;
...
{
....
if(SomeEvent!=null)SomeEvent();
}
</code></pre>
<p>In a multi-threaded environment, how does this code guarantee that another thread will not alter the invocation list of <code>SomeEvent</code> between the check for null and the invocation of the event?</p>

<p>I'm relatively new to programming and I have to write a function that reads in input from the user and to fill two arrays then compare them. I guess what I'm confused on is how to read in both arrays.</p>
<p>This is what I'm supposed to do,</p>
<p>Write a table_diff function that compares two arrays of integers and returns the subscript of the first place they differ. If the arrays are the same, the function should return -1 ex:</p>
<p>345 & 345 --> -1 (same)</p>
<p>345 & 346 --> 2 (differ at index 2)</p>
<p>1234 & 123 --> 3 (differ at index 3)</p>
<p>This is what I have, any help is appreciated! </p>
<pre><code>while((r = scanf("%i", &value)) != 1 && ptra < endptra)
{
*ptra ++ = value;
if (r==1)
printf("No room after reading values\n\n");
else if(r != EOF)
printf("invalid char");
}
while((r = scanf("%i\n", &value))!= 1 && ptrb < endptrb){
*ptrb ++ = value;
if (r==1)
printf("No room after reading values\n\n");
else if(r != EOF)
printf("invalid char");

<p>I have some shapefile (demographic/heat map data in the USA, such as crime in New York) data imported into a sql server 2008 database, field data type: <em>Geography</em>.</p>
<p>How can i get this data, from a <em>select</em> query, in a format which i can then display on google maps or microsoft virtual earth?</p>
<p>thanks!</p>
<p>Edit 1: So far, the best solution has been to use a (free) 3rd Party dll (<a href="http://www.codeplex.com/SharpMap" rel="nofollow noreferrer">SharpMap</a>). I'm hoping someone might suggest some sql tricks in sql2008 to return it in a compatible format ...</p>

<p>How can you express X of Y are true, in boolean logic? a rule like 2 of the following must be true (A, B, C, D, E, F)
is it a form of multiplcation or set operations?<br>
the end result is all the permutations like AB OR AC OR AD, if you said 3 of following it is like ABC, ABD, ABE, etc.. so it is like (A,B,C)^2?</p>
<p>thanks!</p>

<p>I'm working on a school project and I'm getting some weird errors from Xcode. I'm using TextMate's Command+R function to compile the project. Compilation seems to work okay but linking fails with an error message I don't understand. </p>
<p>ld output:</p>
<blockquote>
<p>ld: duplicate symbol text_field(std::basic_istream >&)in /path/final/build/final.build/Release/final.build/Objects-normal/ppc/generics.o and /path/final/build/final.build/Release/final.build/Objects-normal/ppc/main.o
collect2: ld returned 1 exit status</p>
</blockquote>
<p>Below is my file io_functions.cpp This is the only declaration of text_field in the entire project. </p>
<pre><code>#include <string>
#include <iostream>
#include <iomanip>
using namespace std;
#ifndef ENDF
#define ENDF '|'
#define ENDR '\n'
/**

string text_field(istream &in){
string s;
getline(in, s, ENDF);
return s;
}
long long_field(istream &in){
return atol(text_field(in).c_str());

int int_field(istream &in){
return atoi(text_field(in).c_str());
}
double double_field(istream &in){
return atof(text_field(in).c_str());
}
#endif
</code></pre>
<p>What is going wrong? For a number of reasons I don't want to post my project's entire source. </p>

<p>I'm quite confused about the basic concepts of a Hash table. If I were to code a hash how would I even begin? What is the difference between a Hash table and just a normal array? </p>
<p>Basically if someone answered this question I think all my questions would be answered:
If I had 100 randomly generated numbers (as keys), how would I implement a hash table and why would that be advantageous over an array?</p>
<p>Psuedo-code or Java would be appreciated as a learning tool...</p>

<p>I was wondering if someone would be able to help me write a CQL query for NDepend that will show me all the methods in my form class that handle the form events. So I would like to be able to find all the methods that look like this:</p>
<pre><code>Private Sub AddFolderButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddFolderButton.Click
</code></pre>
<p>I have had a look through some of the options but I can't really find anything that does what I need.</p>
<p>I have only just started using NDepend, so I haven't really got used to it yet, but I do know one thing how the hell did I live without it all this time.</p>

<p>Currently we have a DLL that checks whether a username/password is a valid Windows user using the Windows API LogonUser method. We need to enhance it so it checks whether the user belongs to a specified group as well. Is there a Windows method that does that?</p>
<p>Given a Windows username and password, find out whether the user belongs to a specified group.</p>

<p>I'm writing C# code that needs to connect to COM events. I implemented the use of
IConnectionPointContainer and IConnectionPoint thus:</p>
<pre><code> IConnectionPointContainer connectionPointContainer = internalGenerator as IConnectionPointContainer;
if (connectionPointContainer == null)
{
Debug.Fail("The script generator doesn't support the required interface - IConnectionPointContainer");
throw new InvalidCastException("The script generator doesn't support the required interface - IConnectionPointContainer");
}
Guid IID_IScriptGeneratorEvents = typeof(IScriptGeneratorCallback).GUID;
connectionPointContainer.FindConnectionPoint(ref IID_IScriptGeneratorEvents, out m_connectionPoint);
m_connectionPoint.Advise(this, out m_cookie);
</code></pre>
<p>The problem is that when the COM server is actually implemented in .Net (say, C#), after .Net creates it, it handles it as a .Net object, not a COM object. Since the .Net object doesn't implement the IConnectionPointContainer interface, I get null when trying to cast the object to that interface.</p>
<p>Any idea how can i workaround this?
I can of course implement IConnectionPointContainer by myself in the C# COM server, however I would like a simpler solution, which I can easily explain to other developers which need to implement the COM server.</p>
<p>P.S I must use IConnectionPointContainer as the COM server may be implemented in non-.Net (C++, Java).</p>
<p>Thanks,
Inbar</p>

<p>I was wondering if there was some kind of J tool in the java swing library that opens up a file browser window and allows a user to choose a file. Then the ouput of the file would be the absolute path of the chosen file.</p>
<p>Thanks in advance,</p>

<ul>
<li><p>How do I utilize a ?: operator in the SELECT clause of a LINQ query? If this can't be done, how can I emulate one? The goal is to get a CASE block in my select clause. As you might suspect, I'm getting an error: <em>Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.</em></p></li>
<li><p>Is this the proper way, or a sufficient way, to say "from a inner join i on a.ipid=i.id inner join u on i.uid=u.id"? If not, please provide one. Thanks.</p>
<pre><code>var query =
from a in db.tblActivities
from i in db.tblIPs
from u in db.tblUsers
select new {
u.UserName == null
? i.Address
: u.UserName,
a.Request,
a.DateTime };
</code></pre></li>

<p>I know this question had been asked more than a few times, but so far I haven't been able to find a good solution for it.</p>
<p>I've got a panel with other control on it.<br>
I want to draw a line on it and on top of all the controls in the panel</p>
<p>I came across 3 types of solutions (non of them worked the way I wanted) :</p>
<ol>
<li><p>Get the desktop DC and Draw on the screen.<br>
This will draw on other applications if they overlap the form.</p></li>
<li><p>Overriding the panel's "CreateParams":</p></li>
</ol>
<p>=</p>
<pre><code>protected override CreateParams CreateParams {
get {
CreateParams cp;
cp = base.CreateParams;
cp.Style &= ~0x04000000; //WS_CLIPSIBLINGS
cp.Style &= ~0x02000000; //WS_CLIPCHILDREN
return cp;
}
}
</code></pre>
<p>//NOTE I've also tried disabling WS_CLIPSIBLINGS</p>
<p>and then drawing the line OnPaint().
But... Since the panel's OnPaint is called before the OnPaint of the controls in it,
the drawing of the controls inside simply paints on top of the line.<br>
I've seen someone suggest using a message filter to listen to WM_PAINT mesages, and use a timer, but I don't think this solution is either "good practice" or effective.<br>
What would you do ? Decide that the controls inside have finished drawing after X ms, and set the timer to X ms ?</p>
<hr>
<p>This screen shot shows the panel with WS_CLIPSIBLINGS and WS_CLIPCHILDREN turned off.<br>
The Blue line is painted at the Panel's OnPaint, and simply being painted on by the textboxes and label.<br>
The Red line is painted on top only because it's not being painted from the panel's OnPaint (It's actually painted as a result of a Button being clicked)<br>
<img src="https://i73.photobucket.com/albums/i201/sdjc1/temp/screen3.png" alt="alt text"></p>
<hr>
<p>3rd: Creating a transparent layer and drawing on top of that layer.<br>
I've created a transparent control using:</p>
<pre><code>protected override CreateParams CreateParams {

</code></pre>
<p>The problem is still, putting the transparent control on top of the Panel and all its controls.<br>
I've tried bringing it to the front using: "BringToFront()" , but it didn't seem to help.<br>
I've put it in the Line control's OnPaint() handler.<br>
Should I try putting it somewhere else ??<br>
- This also creates issue with having another control on top of the panel. (catching the mouse clicks etc..) </p>
<p><strong>Any help would be greatly appreciated!</strong></p>
<p>**EDIT:
The black line is a sample of what I was trying to do. (used windows paint to paint it)</p>

<p>I just read <a href="https://stackoverflow.com/questions/72271/no-newline-at-end-of-file-compiler-warning">this post</a> about why new-line warnings exist, but to be honest my team has people working on several different platforms and with several different editors (everyone uses what bests suites them), so the warning has become ubiquitous, and since its not really a warning worth taking care of it's become noise and makes finding serious warnings a hassle. </p>
<p>Many times important warnings have gone unnoticed because, people got used to having a gazillion useless warnings pass by, so they obviously just stop looking at them carefully, and with reason IMHO. One could say in our case GCC is crying wolf too much for anyone to take it seriously anymore, which is a bad attitude but its just human nature. </p>
<p>Right now we compile with <code>-Wall</code>, because we want warnings, but is there a counter flag to avoid the new-line warnings?</p>
<p><strong>Note:</strong> I Looked through the manual a bit but didn't find the answer in any place obvious so I gave up.</p>
<p><strong>Note:</strong> In response to Robert Gamble's totally reasonable solution, our code is cross-platform and we have people and builds on Linux, Solaris and Windows, so the new-line... is not under consensus. And Somebody's compiler is always going to cry-wolf. Because there are over 40 developers, and other non programmer staff as well.</p>

<p>In standard php or source code based projects we easily keep all of the code in SVN and each developer can checkout their own copy and collaborate on the same code. </p>
<p>When developing a Drupal site however, much of the work is in "setup". Besides the theme and modules you don't really have any "source code". How do you run multiple instances of the same site so developers can all work at the same time yet share their work?</p>
<p>Example Scenario:</p>
<p>We launch an initial version of a Drupal site with content type "X" created. We also initially launch a view on the site that lists all the nodes of type "X" in chronological order. The client starts using the site, add content, menu items etc.</p>
<p>The next release is planned to add user search ability to that view. The setup for that is contained in the database though. We can copy down the production database to our development version to get the latest data while we work on changing the view. During that time however the client can still be updating the site, making our dev database out of sync. When we are ready to push the new view to production, is there an easier way to do it other than manually repeat the steps to set it up on the production install?</p>

<p>I remember from way back at university using a switch with 'binary search' or 'binary switch'. Something like that, My google foo is broken today. Anyway it goes down like this: You define an array of possible options (Strings usually), some magic happens, and those options in the array become the cases in the switch happens. I do remember that they had to be in alphabetical order for this to work. Can you help me remember the magic? Even a name of what I should be looking at would be fantastic.</p>

<p>Is there a way to have a function return a editable reference to some internal data. Here's an example I hope helps show what I mean.</p>
<pre><code>class foo
{
public int value;
}
class bar
{
bar()
{
m_foo = new foo();
m_foo.value = 42;
}
private m_foo;
foo getFoo(){return m_foo;}
}
class main
{
int main()
{
bar b = new bar();
b.getFoo().value = 37;
}
}
</code></pre>
<p>The return of getFoo() according to "==" is the same as the internal m_foo until I try to edit it. In c/c++ I'd return a reference or pointer.</p>

<p>Ok, this is driving me nuts.</p>
<p>I've done just about everything I can to enable step through debugging of stored procedures of a sql server 2005 database.</p>
<p><a href="http://arjunachith.blogspot.com/2007/05/debugging-stored-procedures-debug.html" rel="noreferrer">http://arjunachith.blogspot.com/2007/05/debugging-stored-procedures-debug.html</a></p>
<p><a href="http://msdn.microsoft.com/en-us/library/zefbf0t6(vs.71).aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/zefbf0t6(vs.71).aspx</a></p>
<p>My currents setup:</p>
<ol>
<li>visual studio 2008 SP1</li>
<li>SQL server 2005 express database (yes you can debug on this)</li>
<li>DEV database on my localmachine with "root" login as sysadmin</li>
</ol>
<p>All I want to do is right click on a stored proc in my server explorer in VS 2008 and see "step into stored procedure". I've done all I can and I can't see that.
I'm just trying to access a local database on my local machine, I've created an account</p>

<p>We need to start adding internationalisation to our program. Thankfully not the whole thing yet, just a few bits, but I want the way we do it to scale up to potentially cover the whole program. The thing is, our program is based on plugins, so not all strings belong in the same place.</p>
<p>As far as I understand it, Java's <code>ResourceBundle</code> work like this. You create a class that extends <code>ResourceBundle</code>, called something like <code>MyProgramStrings</code>, and also language-specific classes called <code>MyProgramStrings_fr</code>, <code>MyProgramStrings_es</code> etc. Each of these classes maps keys (strings) to values (any object). It's up to each of these classes where to get its data from, but a common place for them is a properties file.</p>
<p>You look up values in two stages: first you get the correct bundle, then you query it for the string you want.</p>
<pre><code>Locale locale = Locale.getDefault(); // or = new Locale("en", "GB");
ResourceBundle rb = ResourceBundle.getBundle("MyProgramStrings", locale);
String wotsitName = rb.getString("wotsit.name");
</code></pre>
<p>However, what we need is to combine the results of several locales into a single resource space. For example, a plugin needs to be able to override a string that's already defined, and have that new value returned whenever code looks up the string.</p>
<p>I'm a little lost in all this. Can anybody help?</p>
<hr>
<p><strong>Update:</strong> David Waters asked:</p>
<blockquote>
<p>I have put my answer at the bottom but I would be interested in hearing how you solved this problem.</p>
</blockquote>
<p>Well, we haven't got very far yet - long term WIBNIs always fall victim to the latest crisis - but we're basing it on the interface that a plugin implements, with the convention that resources have the same fully qualified name as the interface.</p>
<p>So an interface <code>UsersAPI</code> may have various different implementations. A method <code>getBundle()</code> on that interface by default returns the equivalent of <code>ResourceBundle.get("...UsersAPI", locale)</code>. That file can be replaced, or implementations of UsersAPI can override the method if they need something more complicated.</p>
<p>So far that does what we need, but we're still looking at more flexible solutions based on the plugins.</p>

<p>If you have a particular line of C code in mind to examine in the machine output, how would you locate it in objdump output. Here is an example</p>
<pre><code>if (cond)
foo;
bar();
</code></pre>
<p>and I want to see if bar was inlined as I'd like.
Or would you use some alternative tool instead of objdump?</p>

<p>I have this PHP script that I wrote to automatically follow users that post messages with certain terms. It works 100% of the time on a bunch of test accounts but then does not work on the account I'd like to use it with. </p>
<p>I've checked the account's API rate limit and it's well within the boundaries. I've also verified that the username and password are correct. If I change nothing else but the username and password to another account it will work, but when changed back (correctly) to the main account nothing happens. I am totally baffled. Has anyone ever come across this?</p>
<p>I'm including the two files used below. If there's any other info that would be helpful, let me know and I'll provide it if I can. Thanks!</p>
<p>Index.php </p>
<pre><code><?php
$url = "http://search.twitter.com/search.atom?q=SEARCHTERM&show_user=true&rpp=100";
$search = file_get_contents($url);
$regex_name = '/\<name\>(.+?) \(/';
preg_match_all($regex_name,$search,$user);
for($i=0;$user[1][$i];$i++)
{
$follow = $user[1][$i];
include("follow.php");
}
?>
</code></pre>
<p>Follow.php</p>
<pre><code><?php
define('TWITTER_CREDENTIALS', 'username:password');
$url = "http://twitter.com/friendships/create/".$follow.".xml";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_USERPWD, TWITTER_CREDENTIALS);
$result= curl_exec ($ch);
curl_close ($ch);
?>
</code></pre>
<p>Quick update on this: Turns out the problem was on Twitter's end--the account in question had tighter than normal API limits imposed for some reason. I'm not marking any responses as the answer since it was a rather idiosyncratic instance.</p>

<p>I'm looking for an alternative, since I find emacs difficult to use. I'd rather use an editor that supports all the usual shortcuts I'm used to, such as arrow keys to move the cursor around, CTRL+SHIFT+RightArrow to select the next word, etc.</p>
<p>Basically, I don't want to have to relearn all my familiar shortcuts just so I can use emacs.</p>
<p>Can anyone recommend a suitable editor?</p>
<p>Another thing - Notepad++ supports LISP syntax coloring, but it doesn't have an integrated LISP console like emacs does. Would it be fine to just have a Notepad++ window and a Command Line window open, side-by-side, and use the command-line whenever I want to run my program?</p>

<p>I'm going to try out turbogears however I'm on windows vista.
however due to firewall proxy problems, it seems i can't download .egg files which is required for setup turbogears to get installed in my windows environment.
I do have a bootable, or I can make a bootable Linux USB, I can try cygwin but I am not sure where to start with cygwin, so I was wondering what would solve my firewall / proxy problem of installing something like turbogears.</p>
<p>if it's possible, is there some non-online version of turbogears that i could just download from visiting a site and then somehow importing that non-online version into my python environment?</p>
<p>thanks so much!:)</p>

<p>What is the best way to give the user feedback for a color selection?<br>
I have a dialog with a "Select Color" push button which pops a <code>QColorDialog</code>. After the selection is made I want to show the user the color selected.<br>
Usually I do this using a <code>QLabel</code> and changing it's background color in the palette. This method is cumbersome and I think not very portable. </p>
<p>Is there a standard way of doing this?</p>

<p>Does anyone have a good way of implementing something like a sequence in SQL server?</p>
<p>Sometimes you just don't want to use a GUID, besides the fact that they are ugly as heck. Maybe the sequence you want isn't numeric? Besides, inserting a row and then asking the DB what the number is just seems so hackish.</p>

<p>Suppose that I have a Java class with a static method, like so:</p>
<pre>
class A
{
static void foo()
{
// Which class invoked me?
}
}
</pre>
<p>And suppose further that class A has an arbitrary number of subclasses:</p>
<pre>
class B extends A { }
class C extends A { }
class D extends A { }
...
</pre>
<p>Now consider the following method invocations:</p>
<pre>
A.foo();
B.foo();
C.foo();
D.foo();
...
</pre>
<p>My question is, how can method <code>foo()</code> tell which class is invoking it?</p>

<p>I'm following several tutorials and references trying to get my kernel set up. I've come across some unfamiliar code in a tutorial that isn't explaining it at all. It's code that I'm told maps the <code>16 IRQs (0-15)</code> to ISR locations <code>32-47</code>:</p>
<pre><code>void irq_remap(void)
{
outportb(0x20, 0x11);
outportb(0xA0, 0x11);
outportb(0x21, 0x20);
outportb(0xA1, 0x28);
outportb(0x21, 0x04);
outportb(0xA1, 0x02);
outportb(0x21, 0x01);
outportb(0xA1, 0x01);
outportb(0x21, 0x0);
outportb(0xA1, 0x0);
}
</code></pre>
<p>The code for <code>outportb()</code> is as follows, but I already have a clear grasp of what its doing:</p>
<pre><code>void outPortB(unsigned short port, unsigned char data)
{
__asm__ __volatile__ ("outb %1, %0" : : "dN" (port), "a" (data));
}
</code></pre>
<p>I should mention that this is on x86 architecture in protected mode. This source code works fine and I understand what it does, but I don't understand how it does it. Can someone explain to me what's going on here, so that in case I need to expand on this I will know what I'm doing?</p>

<p>Consider two tables transaction and category each having their own ID and information.</p>
<p>A transaction can have more than one category, I have read creating a 3rd table to link transaction and category using their IDs is best. But what would you call this table, assuming you would have many like it?</p>
<p>transactionCategories is the best I'm coming up with, is there anything better?</p>

<p>Of course, the immediate answer for most situations is <strong>"yes"</strong>, and I am a firm believer that a process should correctly cleanup any resources it has allocated, but what I have in my situation is a long-running system daemon that opens a fixed number of file descriptors at the startup, and closes them all before exiting.</p>
<p>This is an embedded platform, and I'm trying to make the code as compact as possible, while not introducing any bad style. But since file descriptors are closed before exit anyway, does this file descriptor cleanup code serve any purpose? Do you always close all your file descriptors?</p>

<p>I'm building an ORM library with reuse and simplicity in mind; everything goes fine except that I got stuck by a stupid inheritance limitation. Please consider the code below:</p>
<pre><code>class BaseModel {
/*
* Return an instance of a Model from the database.
*/
static public function get (/* varargs */) {
// 1. Notice we want an instance of User
$class = get_class(parent); // value: bool(false)
$class = get_class(self); // value: bool(false)
$class = get_class(); // value: string(9) "BaseModel"
$class = __CLASS__; // value: string(9) "BaseModel"
// 2. Query the database with id
$row = get_row_from_db_as_array(func_get_args());
// 3. Return the filled instance
$obj = new $class();
$obj->data = $row;
return $obj;
}
}
class User extends BaseModel {
protected $table = 'users';
protected $fields = array('id', 'name');
protected $primary_keys = array('id');
}
class Section extends BaseModel {
// [...]
}
$my_user = User::get(3);
$my_user->name = 'Jean';
$other_user = User::get(24);
$other_user->name = 'Paul';
$my_user->save();
$other_user->save();
$my_section = Section::get('apropos');
$my_section->delete();
</code></pre>
<p>Obviously, this is not the behavior I was expecting (although the actual behavior also makes sense).. So my question is if you guys know of a mean to get, in the parent class, the name of child class.</p>

<p>I am working on a WPF application that opens and displays XPS documents. When the application closes, the specification is the application should delete the opened XPS document for clean up. However, when opening a certain XPS document, the application throws an exception that the file is still in use when it tries to delete it. It is a little weird because it only happens when opening a particular XPS document and only when you have moved beyond the first page. </p>
<p>Some of the codes I used are shown below:</p>
<p>For opening the XPS Document:</p>
<pre><code>DocumentViewer m_documentViewer = new DocumentViewer();
XpsDocument m_xpsDocument = new XpsDocument(xpsfilename, fileaccess);
m_documentViewer.Document = m_xpsDocument.GetFixedDocumentSequence();
m_xpsDocument.Close();
</code></pre>
<p>For navigating the XPS document:</p>
<pre><code>m_documentViewer.FirstPage();
m_documentViewer.LastPage();
m_documentViewer.PreviousPage();
m_documentViewer.NextPage();
</code></pre>
<p>For closing the DocumentViewer object and deleting the file:</p>
<pre><code>m_documentViewer.Document = null;
m_documentViewer = null;
File.Delete(xpsfilename);
</code></pre>
<p>It's all pretty basic and it works with the other documents that we tested. But with the particular XPS document, an exception pops up saying that the file to be deleted is still being used. </p>
<p>Is there something wrong or missing from my code? </p>
<p>Thanks!</p>

<p>I am using UIActivityIndicatorView to showing user that there is something going on, let them wait. But UIActivityIndicatorView looks small, do not have background color, and not very obvious to the user. While in iPhone SDK's UIImagePickerController, it uses the similar mechanism, but with the black background as well as some text besides the indicator.</p>
<p>I am wondering whether there is any existing component to do that task, or I have to implement my own class to perform that task.</p>
<p>Any suggestion are highly welcome, thanks in advance.</p>

<p>I have a Windows application (VS2005/C#) which comes in two versions, Enterprise and Pro. In the Pro version, some of the features and menus are disabled. Currently, I'm doing this by commenting out the disabling code to create the Enterprise version, then I copy each executable file to another location. Obviously this process is fraught with peril... :)</p>
<p>I would like to have two folders for my two executable files, and visual studio should put the code to disable the features in the pro version, and put each in their correct folders. I have installer projects that would pick up the files from there and make the installers for the two versions. That part is already working, but I'm manually copying the two executables into the right folders before I build the installers. So it sucks...</p>
<p>What I'd like to do is something like this:</p>
<pre><code>#ifdef PROVERSION
part1.disable();
part2.disable();
#endif
</code></pre>
<p>Is this possible with Visual studio???</p>
<p>Note, my overall goal is to automate the process of creating the two installers.</p>

<p>I need help writing the following method:</p>
<pre><code>def get_new_location(current_location, target_location, distance_travelled):
...
...
return new_location
</code></pre>
<p>where all locations are (lat,long)</p>
<p>I realize that there are different models for the earth (WGS-84, GRS-80, ...) which take into account the fact that the earth is an ellipsoid. For my purposes, this level of precision is not necessary, assuming a perfect sphere is good enough.</p>
<p><strong>UPDATE</strong></p>
<p>I'm fine tuning my question taking into account some of the responses.</p>
<p><code>benjismith</code> argues that my question cannot be answered because there is more than one shortest path between points on the globe. He has a lot of backing in the form of votes, so I guess there's something I don't understand, because I disagree.</p>
<blockquote>
<p>The midpoint between any two locations
on a sphere is a circular arc.</p>
</blockquote>
<p>I concede that this is true when two points are at complete opposites. By this I mean that both points, while remaining on the surface of the sphere, could not be any further away from each other. In this case there are infinite number of equidistant paths joining both points. This, however, is an edge case, not the rule. In all other cases, the vast majority of cases, there is a single shortest path.</p>
<p>To illustrate: if you were to hold a string which passed through two points, and pulled it tight, would there not be only one possible path on which the string would settle (except the edge case already discussed)?</p>
<p>Now, prior to asking the question, obtaining the distance between two points and the heading was not a problem.</p>
<p>I guess what I should have asked is if the following is valid:</p>
<pre><code>def get_new_location(current_location, target_location, percent_traveled):
new_location.lon = (1-percent_traveled)*current_location.lon+percent_traveled*target_location.lon
new_location.lat = (1-percent_traveled)*current_location.lat+percent_traveled*target_location.lat
return new_location
</code></pre>
<p>If I were to follow this path, would I be following the great-circle, the rhumb line, ... or would I be completely off?
(I know these terms now because of Drew Hall's answer.)</p>

<p>Given the following simple example:</p>
<pre><code> List<string> list = new List<string>() { "One", "Two", "Three", "three", "Four", "Five" };
CaseInsensitiveComparer ignoreCaseComparer = new CaseInsensitiveComparer();
var distinctList = list.Distinct(ignoreCaseComparer as IEqualityComparer<string>).ToList();
</code></pre>
<p>It appears the CaseInsensitiveComparer is not actually being used to do a case-insensitive comparison. </p>
<p>In other words <strong>distinctList</strong> contains the same number of items as <strong>list</strong>. Instead I would expect, for example, "Three" and "three" be considered equal.</p>
<p>Am I missing something or is this an issue with the Distinct operator?</p>

<p>I am looking to parse INSERT and UPDATE MySQL SQL queries in PHP to determine what changes where made from what original data. Now this would be pretty easy to create, but I want to see if there are any existing libraries in PHP to do this.</p>
<p>Basically what I have is a table with all of the above queries that have been run on a database. I have already separated out the table name and type of query. I am looking to create a full change log for user viewing based on this data, so I need to get the values of the original INSERT and then changes that are made in each UPDATE. In the end I need field name and new value and with the record id(s). I'll do the rest of the checking/beautifying, including the column name to human readable and if a field value hasn't actually changed.</p>
<p>At the moment, I probably don't need to do multiple table UPDATE's, but it would be useful.</p>
<p>What libraries are there to do this?</p>

<p>DDL for Database Tables:</p>
<pre><code> Users:
id - int - identity
name - varchar - unique
PCs:
id - int - idnetity
name - varchar - unique
userid - FK to Users
Apps:
id - int - identity
name - varchar
pcid - FK to PCs
</code></pre>
<p>I created a DataContext using the Linq To SQL designer in Visual Studio 2008.</p>
<p>I want to perform this query:</p>
<pre><code>select
users.name,
pcs.name,
apps.name
from
users u
join pcs p on p.userid = u.id
join apps a on a.pcid = p.id
</code></pre>
<p>I was told in another thread where I posted an answer that the following was incorrect and that it created a cross-join.</p>
<pre><code>var query = from u in db.Users // gets all users
from p in u.PCs // gets all pcs for user
from a in p.Apps // gets all apps for pc
select new
{
username = u.Name,
pcname = p.Name,
appname = a.Name
};
</code></pre>
<p>When I execute this query I get the correct results. A cross-join with two records in each table should return 8 records but my query correctly returns the two records.</p>
<p>Am I lucky, or is the person telling me that I'm wrong confused?</p>

<p>I'm writing a wrapper class for a command line executable. This exe accepts input from <code>stdin</code> until I hit <code>Ctrl+C</code> in the command prompt shell, in which case it prints output to <code>stdout</code> based on the input. I want to simulate that <code>Ctrl+C</code> press in C# code, sending the kill command to a .NET <code>Process</code> object. I've tried calling <code>Process.Kill()</code>, but that doesn't seem to give me anything in the process's <code>StandardOutput</code> <code>StreamReader</code>. Might there be anything I'm not doing right? Here's the code I'm trying to use:</p>
<pre><code>ProcessStartInfo info = new ProcessStartInfo(exe, args);
info.RedirectStandardError = true;
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
info.UseShellExecute = false;
Process p = Process.Start(info);
p.StandardInput.AutoFlush = true;
p.StandardInput.WriteLine(scriptcode);
p.Kill();
string error = p.StandardError.ReadToEnd();
if (!String.IsNullOrEmpty(error))
{
throw new Exception(error);
}
string output = p.StandardOutput.ReadToEnd();
</code></pre>
<p>The output is always empty, even though I get data back from <code>stdout</code> when I run the exe manually.</p>
<p><strong>Edit</strong>: This is C# 2.0 by the way.</p>
