347,274 | <p>I have written a <a href="http://osirisdevelopment.com/BatteryBar" rel="nofollow noreferrer">toolbar</a> that runs on the taskbar. Unfortunately, after it is installed, the user has to enable it manually. Is there a way to tell explorer to open (or close) a given toolbar?</p>
<p>I would like for the installer, NSIS, to turn on the toolbar when the installation is complete (I realize that a plugin would be necessary).</p>
<p>I also want to know if it's possible to automatically enable a toolbar for all users, for example in a corporate environment where multiple users would share a PC.</p>

347,281 | <p>After trying to setup my site for Google Webmaster Tools I found that my Custom ASP.NET 404 page was not returning the 404 status code. It displayed the correct custom page and told the browser that everything is OK. This is consider a soft 404 or false 404. Google doesn't like this. So I found many articles on the issue but the solution I want didn't seem to work.</p>
<p>The solution I want to work is adding the following two lines to the code behind Page_Load method of the custom 404 page.</p>
<pre><code>Response.Status = "404 Not Found";
Response.StatusCode = 404;
</code></pre>
<p>This doesn't work. The page still returns 200 OK. I found however that if I hard code the following code into the design code it will work properly.</p>
<pre><code><asp:Content ID="ContentMain" ContentPlaceHolderID="ContentPlaceHolderMaster" runat="server">
<%
Response.Status = "404 Not Found";
Response.StatusCode = 404;
%>
... Much more code ...
</asp:content>
</code></pre>
<p>The page is using a master page. And I am configuring custom error pages in my web.config. I would really rather use the code behind option but I can't seem to make it work without putting a the hack inline code in the design / layout.</p>

347,286 | <p>So I'm having a path issue on OS X Leopard. It seems OS X is adding other paths that I'm not stating and it's messing with my path priority. I only have a <code>.bash_login</code> file, I don't have a <code>.bashrc</code> or a .profile file. My <code>.bash_login</code> file is as such:</p>
<pre><code>export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"
</code></pre>
<p>When I run export this is the path it returns:</p>
<pre><code>PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin"
</code></pre>
<p>Any ideas on what could be putting /usr/bin in there and how I could get <code>/usr/local/bin</code> to be a higher priority.</p>
<p>I'm tagging this for Rails too because that's what I'm working on right now... it seems the Mac built-in Ruby, Rails, and Gems are taking priority over the one I have installed at <code>/usr/local/bin</code>, figured maybe you fellow Rubyists could help too.</p>

347,294 | <p>So I'm trying to take a bilinear interpolation algorithm for resizing images and add in alpha values as well. I'm using Actionscript 3 to do this, but I don't really think the language is relevant.</p>
<p>The code I have below actually works really well, but edges around "erased" regions seem to get darker. Is there an easy way for it to not include what I can only assume is black (0x00000000) when it's finding its average?</p>
<p>Code:</p>
<pre><code>x_ratio = theX - x;
y_ratio = theY - y;
x_opposite = 1 - x_ratio;
y_opposite = 1 - y_ratio;
a = getPixel32(x, y);
be =getPixel32(x + 1, y);
c = getPixel32(x, y + 1);
d = getPixel32(x + 1, y + 1);
alph = (t(a) * x_opposite + t(be) * x_ratio) * y_opposite + (t(c) * x_opposite + t(d) * x_ratio) * y_ratio;
red = (r(a) * x_opposite + r(be) * x_ratio) * y_opposite + (r(c) * x_opposite + r(d) * x_ratio) * y_ratio;
green = (g(a) * x_opposite + g(be) * x_ratio) * y_opposite + (g(c) * x_opposite + g(d) * x_ratio) * y_ratio;
blue = (b(a) * x_opposite + b(be) * x_ratio) * y_opposite + (b(c) * x_opposite + b(d) * x_ratio) * y_ratio;
</code></pre>

<pre><code>a = getPixel32(x, y);

347,298 | <p>I have a c++ program that is using the openMPI library to pass messages between different processors. It is a parallel program that uses a genetic algorithm to get a good solution for the traveling salesperson problem. I am trying to set up the MPI environment on my two dual processor computers at my house so that I can run it.
When I first created this program a year ago, I was able to run it fine on a cluster that was not set up by me. The problem that I am having now is that whenever I run it, all the processes are saying that they are of rank 0. If I have 3 nodes, instead of them being nodes 1, 2, and 3, they are all node 0. If anyone knows what is going on, I would sure appreciate some help. Thanks.</p>

347,325 | <p>I need to get a file into memory in my app from a secured web location. I have the URL of the file to capture, but can't seem to get the security issue resolved. Here's the code from the <a href="http://groovy.codehaus.org/Simple+file+download+from+URL" rel="nofollow noreferrer">Cookbook samples page</a>:</p>
<pre><code>def download(address)
{
def file = new FileOutputStream(address.tokenize("/")[-1])
def out = new BufferedOutputStream(file)
out << new URL(address).openStream()
out.close()
}
</code></pre>
<p>and here's my "memory" version of the same function which should return a byte array of the file's contents:</p>
<pre><code>def downloadIntoMem(address)
{ // btw, how frickin powerful is Groovy to do this in 3 lines (or less)
def out = new ByteArrayOutputStream()
out << new URL(address).openStream()
out.toByteArray()
}
</code></pre>
<p>When I try this against an unsecured URL (pick any image file you can find on the net), it works just fine. However, if I pick a URL that requires a user/password, no go. </p>
<p>All right, done a bit more work on this. It seems that the Authenticator method <strong>does</strong> work, but in a round-about way. The first time I access the URL, I get a 302 response with a location to a login server. If I access that location with an Authenticator set, then I get another 302 with a Cookie and the location set back to the original URL. If I then access the original, the download occurs correctly.</p>
<p>So, I have to mimic a browser a bit, but eventually it all works.</p>
<p>Making this a community wiki, so others can add other methods.</p>
<p>Thanks!</p>

347,338 | <p>Is releasing objects on a programs exit/close needed?</p>
<p>In other words, let us say for the sake of argument, you have a button that closes your application, but right before you close you display an image, and then you close the application.</p>
<p>Do you need to release that image view before you close the application? Will the memory automatically be freed when the program exits, or if you don't release it will the memory stay somehow "active"?</p>
<p>I understand that you "should" release it, my question is about the technical side of it, and what happens behind the scenes.</p>

347,377 | <p>Both Session.Clear() and Session.Abandon() get rid of session variables. As I understand it, Abandon() ends the current session, and causes a new session to be created thus causing the End and Start events to fire.</p>
<p>It seems preferable to call Abandon() in most cases, such as logging a user out. Are there scenarios where I'd use Clear() instead? Is there much of a performance difference?</p>

347,396 | <p>I'm using the Accessibility API to detect when a certain application opens windows, closes windows, when the windows are moved or resized, or made main and/or focused. However the client app seems to move a window to front without an Accessibility API notification being
fired.</p>
<p>How can my application detect when another application brings a window to front, without making it key?</p>
<p>I'm hoping to find a solution that works on OS X 10.4 and 10.5</p>
<p>More info:
I'm using these statements at the moment. They work fine when the user manually selects a window to bring it to front. But it doens't work when the app itself is bringing the window to the front.</p>

<a href="http://www.timkjaerlange.com/wip/co2penhagen/" rel="nofollow noreferrer">http://www.timkjaerlange.com/wip/co2penhagen/</a></p>
<p>I got a problem with this unordered list. IE seems to add extra top-margin for every li-element, making my navigation look like a flight of stairs:
<a href="http://dl.getdropbox.com/u/228089/ie-prob.jpg" rel="nofollow noreferrer">http://dl.getdropbox.com/u/228089/ie-prob.jpg</a></p>
<p>I'm using conditional comments to target IE. I tried:</p>
<pre><code>ul#mainnav li { top-margin: 0;}
</code></pre>
<p>But that doesn't do anything. I wish there was a Firebug-style plugin for IE, that would make it easier to sort out problems like these.</p>
<p>Any ideas regarding what could be causing this problem?</p>

347,439 | <p>I have a mouseenter and mouseleave event for a Panel control that changes the backcolor when the mouse enters and goes back to white when it leaves.</p>
<p>I have Label control within this panel as well but when the mouse enters the Label control, the mouseleave event for the panel fires.</p>
<p>This makes sense but how do I keep the backcolor of the Panel the same when the mouse is in its area without the other controls inside affecting it?</p>

347,441 | <p>I want to clear a element from a vector using the erase method. But the problem here is that the element is not guaranteed to occur only once in the vector. It may be present multiple times and I need to clear all of them. My code is something like this:</p>
<pre><code>void erase(std::vector<int>& myNumbers_in, int number_in)
{
std::vector<int>::iterator iter = myNumbers_in.begin();
std::vector<int>::iterator endIter = myNumbers_in.end();
for(; iter != endIter; ++iter)
{
if(*iter == number_in)
{
myNumbers_in.erase(iter);
}
}
}
int main(int argc, char* argv[])
{
std::vector<int> myNmbers;
for(int i = 0; i < 2; ++i)
{
myNmbers.push_back(i);
myNmbers.push_back(i);
}
erase(myNmbers, 1);
return 0;
}
</code></pre>
<p>This code obviously crashes because I am changing the end of the vector while iterating through it. What is the best way to achieve this? I.e. is there any way to do this without iterating through the vector multiple times or creating one more copy of the vector?</p>

347,449 | <p>I'll be using the <a href="http://www.codeplex.com/MSFTDBProdSamples/Release/ProjectReleases.aspx?ReleaseId=4004" rel="nofollow noreferrer">AdventureWorks Database</a> to illustrate my problem.</p>
<p>I need to show for a particular customer a list of OrderDate with the most Orders.</p>
<p>My intial attempt was as follows:</p>
<pre><code>SELECT CustomerID, OrderDate, COUNT(1) Cnt
FROM Sales.SalesOrderHeader
WHERE CustomerID = 11300
GROUP BY CustomerID, OrderDate
ORDER BY Cnt DESC
</code></pre>
<p>This will get us the following result:</p>
<pre><code>CustomerID OrderDate Cnt
----------- ---------- ----
11300 2003-11-22 00:00:00.000 2
11300 2004-01-28 00:00:00.000 2
11300 2004-02-18 00:00:00.000 2
11300 2004-02-08 00:00:00.000 2
11300 2004-02-15 00:00:00.000 1
11300 2004-03-11 00:00:00.000 1
11300 2004-03-24 00:00:00.000 1
11300 2004-03-30 00:00:00.000 1
11300 2004-04-28 00:00:00.000 1
11300 2004-05-03 00:00:00.000 1
11300 2004-05-17 00:00:00.000 1
11300 2004-06-18 00:00:00.000 1
...
</code></pre>
<p>Not exactly what I wanted, as the result should only show all records where Cnt = 2, like so:</p>
<pre><code>CustomerID OrderDate Cnt
----------- ---------- ----
11300 2003-11-22 00:00:00.000 2
11300 2004-01-28 00:00:00.000 2
11300 2004-02-18 00:00:00.000 2
11300 2004-02-08 00:00:00.000 2
</code></pre>
<p>I'm stuck because I can't wrap my mind around two problems:</p>
<p>1) A customer might have more than one OrderDate with the same Cnt value. This means I can't do something like TOP 1 to get the desired result.<br>
2) Because the number of Orders for each customer may be different, I cannot use the following SQL statement:</p>
<pre><code>SELECT CustomerID, OrderDate, COUNT(1) Cnt
FROM Sales.SalesOrderHeader
WHERE CustomerID = 11300
GROUP BY CustomerID, OrderDate HAVING COUNT(1) > 1
ORDER BY Cnt DESC
</code></pre>
<p>This will work for getting the right result for this customer, but will definitely be wrong if the next customer has only one Order for a particular day.</p>
<p>So, either the query is impossible in this situation, or I am approaching the query in the wrong way. Any ideas on this problem is appreciated. </p>
<p>Also, since this will be a query in a stored procedure, any ideas on solving this in T-SQL will be acceptable.</p>
<p>UPDATE: Thanks to <a href="https://stackoverflow.com/questions/347449/sql-statement-help-select-list-of-customerid-orderdate-with-the-most-records-in#347460">Mehrdad</a>, I've been introduced to <a href="http://msdn.microsoft.com/en-us/library/ms190766(SQL.90).aspx" rel="nofollow noreferrer">Common Table Expressions</a>, and Life is Good®. :) </p>

<hr>
<pre><code>class Program
{
public static string[] E = { "i", "go", "school", "to", "at" };
public static string[] A = { "Je", "vais", "ecole", "a", "a" };

Regex Expression = new Regex(@"[a-zA-Z]+");
MatchCollection M = Expression.Matches(s);
foreach (Match x in M)
str = str + " " + TranslateWord(x.ToString());
return str;
}
public static string TranslateWord(string s)
{
for (int i = 0; i < E.Length; i++)
if (s.ToLower() == E[i].ToLower())
return A[i];
return "Undefined";
}
</code></pre>
<hr>
<p>here I want to enter the the whole string and the code should translate it with the number, now i know how to do the word (by spliting them and translate) but what about the numbers)</p>
<pre><code> static void Main(string[] args)
{
string str = "I go to school at 8";
Console.WriteLine(Translate(str));
}

347,497 | <p>I am writing a web-framework for Python, of which the goal is to be as "small" as possible (currently under 100 lines of code).. You can see the current code <a href="http://github.com/dbr/pyerweb/tree/master" rel="nofollow noreferrer">on github</a></p>
<p>Basically it's written to be as simple to use as possible. An example "Hello World" like site:</p>
<pre><code>from pyerweb import GET, runner
@GET("/")
def index():
return "<strong>This</strong> would be the output HTML for the URL / "
@GET("/view/([0-9]+?)$")
def view_something(id):
return "Viewing id %s" % (id) # URL /view/123 would output "Viewing id 123"
runner(url = "/", # url would be from a web server, in actual use
output_helper = "html_tidy" # run returned HTML though "HTML tidy"
</code></pre>
<p>Basically you have a function that returns HTML, and the GET decorator maps this to a URL.</p>
<p>When <code>runner()</code> is called, each decorated function is checked, if the URL regex matches the request URL, the function is run, and the output is sent to the browser.</p>
<p>Now, the problem - outputting headers. Currently for development I've just put a line before the <code>runner()</code> call which does <code>print Content-type:text/html\n</code> - this is obviously a bit limiting..</p>
<p>My first ideas was to have the functions return a dict, something like..</p>
<pre><code>@GET("/")
def index():
return {
"html": "<html><body>...</body></html>",
"headers": {"Location":"http://google.com"}
}
</code></pre>
<p>I really don't like this - having to return a dict with a specifically named key isn't nearly as nice as just returning a string..</p>
<p>I could check if the returned data is a dict, if so use <code>returned_data['html']</code> as the output, if it's a string, there is no custom headers to be sent... but this means to go from no headers (which would be the case a huge majority of the time) to headers, you'd have to change the return function from <code>return my_html</code> to <code>return {'html':my_html}</code> which isn't very elegant either..</p>
<p>After writing this, I discovered "Sinatra" - a similar-in-use Ruby library, and looked at how it dealt with headers:</p>
<pre><code>get "/" do
content_type 'text/css', :charset => 'utf-8'
end
</code></pre>
<p>This seems like it could be nice enough in Python:</p>
<pre><code>@GET("/")
def index():
header("location", "http://google.com")
</code></pre>
<p>To implement this, I was considering changing how the functions are executed - instead of simply using the return value, I would change <code>sys.stdout</code> to a StringIO, so you could do..</p>
<pre><code>def index():
print "<html>"
print "<head><title>Something</title></head>"
print "<body>...</body>"
print "</html>
</code></pre>
<p>..without having to worry about concatenating a bunch of strings together. The upshot of this is I could have a separate stream for headers, so the above <code>header()</code> function would write to this.. Something like:</p>
<pre><code>def header(name, value):
pyerweb.header_stream.write("%s: %s" % (name, value))
</code></pre>
<p>Basically, the question is, how would you output headers from this web-framework (mostly in terms of <em>use</em>, but to a lesser extent implementation)?</p>

<p>Basically whats happening in the sample below is that an exception is thrown in the <code>DoWork</code> event handler of a <code>BackgroundWorker</code>. The <code>RunWorkerCompleted</code> event handler rethrows a new exception with the original as the inner exception.</p>
<p>Why does the inner exception show up in the <code>ThreadException</code> event handler and not the acutal exception being thrown? If I do not provide an inner exception in the <code>RunWorkerCompleted</code> event handler, the correct exception will show up.</p>

BackgroundWorker worker = new BackgroundWorker();

worker.DoWork += new DoWorkEventHandler(worker_DoWork);
worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
worker.RunWorkerAsync();
}
void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if (e.Error != null)
{
throw new Exception("worker_RunWorkerCompleted", e.Error);

347,528 | <p>I'm fairly new to ASP.NET MVC, and I'm having a little trouble with scripts... in particular, I want to use jQuery in most pages, so it makes sense to put it in the master page. However, if I do (from my <code>~/Views/Shared/Site.Master</code>):</p>
<pre><code><script src="../../Scripts/jquery-1.2.6.js" type="text/javascript"></script>
</code></pre>
<p>Then that is literally what goes down to the client - which of course only works if our current route happens to have the right number of levels. Starting with <code>~/Scripts/...</code> doesn't work. Starting with <code>/Scripts/...</code> would only work if the project was at the site root (which I don't want to assume).</p>
<p>I have one working approach (I'll post below) - but: am I missing something?</p>
<p>I'd rather not have to involve a script-manager, as that seems to defeat the simplicity of the ASP.NET MVC model... or am I worrying too much?</p>
<p>Here's the way I can get it working, which works also for non-trivial virtuals - but it seems over-complicated:</p>
<pre><code><script src="<%=Url.Content("~/Scripts/jquery-1.2.6.js")%>" type="text/javascript"></script>

347,551 | <p>Given a file tree - a directory with directories in it etc, how would you write a script to create a diagram of the file-tree as a graphic file that I can embed in a word processor document.
I prefer vector (SVG, EPS, EMF...) files.
The tool must run on Windows, but preferably cross-platform.
The tool may be commercial but preferably free.</p>
<p>Update 2012-02-20.
The question was related to a documentation sub project. I had to explan where files (in particular resources and configuration files) reside.
I ended up with using dos tree command. I both screen grabbed the result (for short folders) AND for longer folders I redirected to a text file, which I then edited. For example if a subfolder contained 20 similarly typed files that individually were not important to the point I was making, I left just two and replaced the rest with one ... line. I then printed out the file to console again and screen grabbed it.
Before screen grabbing I had to modify foreground color to black and background color to white, to look better and save ink in a document should that be printed.</p>
<p>It is very surprising that there is no better tool for it. If I had time, I'd write a Visio Extension or may be some command line that produces SVG. SVG being HTML5 substandard, would even allow painless inclusion into online documentation.</p>
<p>Update 2017-10-17.
I am sorry that this question was removed as not belonging to SO. So I have re-worded it. I need a script - not a WYSIWYG tool. So any scripting language or library is ok. So it is a code - writing question, and I believe belongs to SO. </p>

347,553 | <p>With the JavaFX 1.0 release I am trying to layout some SwingButton instances in a HBox such that they are aligned to the right. A lot of the tutorials on the net (admittedly pre 1.0 release) talk about layout classes (FlowPanel et. al) which dont seem to be in this release. Whats the simplest way to achieve this seemingly simple task?</p>

347,564 | <p>I have a problem with simple c++ programs... </p>
<p>I would like to install a program, but always have the error like "c++ compiler is unable to create executables"...</p>
<p>Now I tried to compile a simple "hello world" program, but I get errors as I would if I compile a c++ program with a c compiler ("`cout' undeclared"... although I included iostream)...</p>
<p>Now I am not sure, if g++ does not work on my machine?</p>
<p>Does anyone know about how to fix this problem?</p>
<p>Thank you very much in advance...<br>
Chris</p>
<hr>
<p><em>Added</em> In response to Pax's answer:</p>
<p>Well, I think, my code is okay, I can compile it on another machine, and I use the namespace std...</p>
<p>So, it's not possible, that the configuration of g++ is mismatched or something like that...?</p>

347,572 | <p>I'm new to iPhone and Apple development and working on my first application. It simple with only a TableView and a "detail view" when an item in a table is selected.</p>
<p>What I want to do is change the background color of the cell in the TableView based on some action taken in my "detail view".</p>
<p>When the application initially loads I customize the colors in <code>-cellForRowAtIndexPath:</code> method, but when user navigates back from my detail view that function is not called, so my table view doesn't have the colors updated. The only way to get that refreshed now is to exit the application and start it up again. (I persist their selection with NSUserDefaults.)</p>
<p>Obviously, I want the table view to be refreshed when they come back form the detail view, but I don't know how to get a reference to a cell and in which method to do that. I'm assuming it should go in <code>-viewDidAppear</code>, since that is called everything the view is shown.</p>

347,574 | <p>This is a follow-up to a <a href="https://stackoverflow.com/questions/347109/how-do-i-concisely-implement-multiple-similar-unit-tests-in-the-python-unittest">previous question</a> of mine.</p>
<p>In the previous question, methods were explored to implement what was essentially the same test over an entire family of functions, ensuring testing did not stop at the first function that failed.</p>
<p>My preferred solution used a metaclass to dynamically insert the tests into a unittest.TestCase. Unfortunately, nose does not pick this up because nose statically scans for test cases.</p>
<p>How do I get nose to discover and run such a TestCase? Please refer <a href="https://stackoverflow.com/questions/347109/how-do-i-concisely-implement-multiple-similar-unit-tests-in-the-python-unittest#347175">here</a> for an example of the TestCase in question.</p>

347,592 | <p>The title pretty much says it all. I'm using a TClientDataset to store an array of objects, and one of the objects has a member defined as a <strong>set of</strong> an enumerated type. As I understand it, Delphi sets are bitfields whose size can vary from 1 to 32 bytes depending on how much data they contain, and Delphi doesn't define a TSetField. What sort of field should I use to load this value into?</p>

347,606 | <p>I was curious as to what other shops are doing regarding base application frameworks? I look at an application framework as being able to provide additional or extended functionality to improve the quality of applications built from it.</p>
<p>There are a variety of out of the box frameworks, such as Spring (or Spring.NET), etc. I find that the largest problem with these being that they are not a la carte. Basically, they have too much functionality and unless every piece of that functionality is the best implementation available, chances are that you will end up using a patchwork of multiple frameworks to accomplish these tasks - causing bloat and confusion. This applies to free and commercial systems, in my opinion.</p>
<p>Of course, writing is largely re-inventing the wheel. I don't think it is without merit, though, as it provides the most customizable option. Some things are just too large to develop, though, and seem to be poorly implemented or not implemented at all in this case because of the hesitation to commit to the upfront costs of development.</p>
<p>There are a large variety of open source projects that address individual portions of a could-be application framework as well. These can be adopted or assimilated (obviously depending upon license agreements) to help frame in a comprehensive framework from diverse sources.</p>
<p>We approached the situation by looking at some of the larger concerns in our applications across the entire enterprise and came up with a list of valid cross-cutting concerns and recurring implementation issues. In the end, we came up with hybrid solution that is partially open source, partially based on existing open source options, and partially custom developed.</p>
<p>A few examples of things that are in our framework:</p>
<ul>
<li>Exception and event logging providers. A simple, uniform means by which every application can log exceptions and events in an identical fashion with a minimal coding effort. Out of the box, it can log to a SQL Server, text file, event viewer, etc. It contains extensibility points to log to other sources, as well.</li>
<li>Variable assignment enforcement. A generic class that exposes extension methods based upon the object type, using a syntax that is inspired by JUnit. For example, to determine if myObject is not null, we can do a simple Enforce.That(myObject).IsNotNull(); or determine if it is a specific type by doing a simple Enforce.That(myObject).IsOfType(typeof(Hashtable)); Enforcement failures raise the appropriate exception, both reducing the amount of code and providing consistency in implementation.</li>
<li>Unit testing helpers. A series of classes, based upon reflection that can automatically test classes and their properties. (Inspired by <a href="http://www.codeplex.com/classtester" rel="nofollow noreferrer">Automatic Class Tester</a> from CodePlex) but written from the ground up. Helps to simplify the creation of unit tests for things that are traditionally hard or time-consuming to test.</li>
</ul>
<p>We have also outright adopted some other functionality, as is. For example, we are using <a href="http://postsharp.org" rel="nofollow noreferrer">PostSharp</a> for AOP, <a href="http://code.google.com/p/moq" rel="nofollow noreferrer">moq</a> for mocking, and <a href="http://code.google.com/p/autofac/" rel="nofollow noreferrer">autofaq</a> for DI.</p>
<p>Just wondering what other people might have done and what concerns your framework addresses that you did not find tooling that you were satisfied with? As for our experience, we are definitely reaping the benefits of the new framework and are content with the approach that we have taken.</p>

347,675 | <p>I have a class like this:</p>
<pre><code>public class myClass
{
public List<myOtherClass> anewlist = new List<myOtherClass>;
public void addToList(myOtherClass tmp)
{
anewList.Add(tmp);
}
}
</code></pre>
<p>So I call "addToList" a hundred times, each adding a unique item to the list. I've tested my items to show that before I run the "addToList" method, they are unique. I even put a line in to test "tmp" to make sure it was what I was expecting.</p>
<p>However, when I do this (lets say myClass object is called tmpClass):</p>
<pre><code>int i = tmpClass.anewList.Count();
for (int j = 0; j<i; j++)
{
//write out each member of the list based on index j...
}
</code></pre>
<p>I get the same exact item, and it's the last one that was written into my list. It's as if when I add, I'm overwriting the entire list with the last item I've added. </p>
<p>Help? This makes no sense.
I've also tried List.Insert, where I'm always inserting at the end or at index 0. Still no dice. Yes, I'm doubly source my indexing is correct and when I do my test I'm indexing through each of the elements.</p>
<p>:)</p>
<p>UPDATE:
Okay, I tried this and still had the same problem:</p>
<pre><code>foreach(myOtherClass tmpC in tmpClass.anewList)
{
Console.WriteLine(tmpC.theStringInMyClass.ToString());
}
</code></pre>
<p>and still for each of the 100 items, I got the same string output... I'm sure I'm doing something completely stupid, but I don't know what yet. I'm still 100% sure that the right string is getting passed in to begin with.</p>

347,690 | <p>Does any of you have a clue how to alter the contents of <code>Security.framework/TrustStore.sqlite3</code>. It seems as if the iPhone uses it to store trusted CA certificates. I really want my iPod touch to trust my custom certificate. Beside that, does anyone of you know an app (win32) to edit sqlite3 database files (except sqliteman, this one always crashes for me).</p>

347,703 | <p>I made an array in PHP which holds a bucnh of unix timestamps.</p>
<p>I'm trying to make a function that will return an array containing the indexes of the 3 largest numbers in that array.</p>
<p>For instance, if the largest numbers are located at indexes 3,5 and 8</p>
<p>And if the largest is 5, second largest is 8 and smallest of the three is number 3, I want an array that holds the values (5,8,3) in that order.</p>
<p>And frankly, I don't have a clue how to pull this off. Does anybody know how to do this?</p>

<p>Does anyonew know if this is possible? </p>
<p>I've investigated using <code>CALayer</code> and have run through all the pragmatic programmer Core Animation podcasts, but I'm still no clearer on how to create this kind of transform on an iPhone.</p>
<p>Any help, pointers or example code snippets would be really appreciated!</p>

347,724 | <p>I have a Page with a UserControl on it. If the user presses Esc while anywhere on Page I want to handle.</p>
<p>I thought this would be as easy as hooking up the PreviewKeyDown event, testing for the Esc key, and then handling it. However, when I placed I breakpoint in the event handler I found it was never getting called. I thought perhaps the UserControl might be getting hit, so I tried PreviewKeyDown there... same result.</p>
<p>Does anyone know the proper place to test for a KeyDown or PreviewKeyDown on a Page object?</p>

347,798 | <p>I need to change an element's ID using jQuery. </p>
<p>Apparently these don't work:</p>
<pre><code>jQuery(this).prev("li").attr("id")="newid"
jQuery(this).prev("li")="newid"
</code></pre>
<p>I found out that I can make it happen with the following code:</p>
<pre><code>jQuery(this).prev("li")show(function() {
this.id="newid";
});
</code></pre>
<p>But that doesn't seem right to me. There must be a better way, no? Also, in case there isn't, what other method can I use instead of show/hide or other effects? Obviously I don't want to show/hide or affect the element every time, just to change its ID.</p>
<p>(Yep, I'm a jQuery newbie.)</p>
<p><strong>Edit</strong><br>
I can't use classes in this case, I must use IDs.</p>

347,804 | <p>I'm building a web application that guides my users through the configuration and installation of an application. It builds a set of configuration files dynamically, then sends them in an archive (.ZIP file) along with an installer for the application. The web page is generated from a linux shell script (sorry), and for security reasons, I'd prefer the file be sent directly from the script, rather than as a link, so the user can't access it directly.</p>
<p>Here's the process: Once the user has entered some information, and the files have been generated, I want to display a page with instructions, then start the download automatically, without asking the user to click a "download this file" link:</p>
<pre><code>#!/bin/bash
echo_header_and_instructions # Standard HTML
<Magic HTML tag to start transfer> # ??? What goes here???
command_to_stream_the_files # Probably 'cat'
echo_end_tags # End the page.

347,812 | <p>Is there a way to be <strong>sure</strong> that a page is coming from cache on a production server and on the development server as well?</p>
<p>The solution <strong>shouldn't</strong> involve caching middleware because not every project uses them. Though the solution itself might <strong>be</strong> a middleware.</p>
<p>Just checking if the data is stale is not a very safe testing method IMO.</p>

internal abstract void SomeOtherMethod();

347,851 | <p>The project I'm working on has two type of accounts, "<code>people</code>" and "<code>companies</code>". </p>
<p>I hold a single "<code>users</code>" table with all the accounts and just the basic info needed for login (email, pass, etc), and two other tables "<code>user_profiles</code>" (regular people) and "<code>company_profiles</code>" (companies) that hold more specific columns for each type, both of the tables linked to the general "<code>users</code>" table via a "<code>profile_user_id</code>" column.</p>
<p>But, whenever I want to list users that can be both people and companies, I use :</p>
<p>"<code>select user_id, user_type, concat_ws('', concat_ws(' ', user_profiles.profile_first_name, user_profiles.profile_last_name), company_profiles.profile_company_name) as user_fullname</code>".</p>
<p>When I list these users I know whether they're people or companies by the "<code>user_type</code>". </p>
<p>Is my approach using <code>concat_ws</code> the right (optimal) one? I did this instead of <code>select</code>-ing every <code>*_name</code> to avoid returning more columns than necessary.</p>
<p>Thanks</p>
<p>EDIT: the query above continues like: <code>from users left join user_profiles on ... left join company_profiles on ...</code></p>

347,918 | <p>I would like to generate some JavaScript on the server side in ASP.Net MVC. Is there a view engine that supports this? Ideally I would like to be able to get JavaScript from an url like: </p>
<pre><code>http://myapp/controller/action.js
</code></pre>
<p>I've looked at the MonoRail project, and they seem to have this feature, but it's very lacking in documentation, and I can't find any ports to ASP.Net MVC.</p>
<p><strong>Edit:</strong> The idea is to be able to render a page both as standard HTML by using a url like:</p>
<pre><code>http://myapp/controller/action
</code></pre>
<p>and as js (specifically an ExtJS component) by using the first url in the question. There would be only a single action in the controller, but two views: one for HTML and one for JS.</p>
<p><strong>Edit 2:</strong> I basically wanted to achieve the same result as <a href="http://www.pagebakers.nl/2007/06/05/using-json-in-cakephp-12/" rel="nofollow noreferrer">router extension parsing/request handling</a> in CakePHP.</p>

<p>Are there any models or design patterns that are commonly used in this case? A little bit of sample code would be greatly appreciated. Thank you!</p>

347,954 | <p>How can I do a script to catch strings as input and open them on a Firefox document? Each link would go to a different window or tab. Any ideas would be much appreciated.</p>
<p>I just want to be able to take some links and open them. For example I have 50 Links. And copying and parsing those 50 Links take a really long time and also a lot of work. If I can just write a script to read those links and let the computer do the work, it will be very helpful for me. I just don't know how to write that or where because it does not sound too hard (just gotta know how to). Thanks for any suggestions. </p>

347,969 | <p>My question is whether or not Flex's fcsh can be called from within a PHP script. Here is the background:</p>
<p>I have been created a simple process that creates a simple quiz/tutorial by converting a text file into a .mxml file and compiling to a .swf file using the mxmlc compiler. This works well from the command line, but I wanted to make the process easier by creating a web-interface to do this. My initial attempts with PHP's exec() function have not worked. The Python scripts I use to create the .mxml file work fine (using exec()), but I have not been able to get the mxmlc compiler to work.</p>
<p>After searching on the Web and on this site, I believe that using fcsh (instead of mxmlc) may be the way to go. Using fcsh would certainly compile the .mxml file faster (after the first run), and I think that fcsh can be launched as a service that might be able to be called from PHP.</p>
<p>On the other hand, maybe I am approaching this the wrong way. Would it be better to write a Flex application that calls fcsh and avoid using PHP?</p>
<p><strong>Edit:</strong> Using fcshctl as hasseg suggested in his answer below worked very well. Thanks Ali.</p>

348,021 | <p>By means of a regular expression and Greasemonkey I have an array of results that looks like:<br>
<code>choice1, choice2, choice3, choice3, choice1, etc..</code></p>
<p>My question is how do I tally up the choices so I know how many times choice1 is in the array, choice2 is in the array, etc. if I do not know exactly how many choices there are or what they are.</p>
<p>The ultimate goal is to create a Greasemonkey script that stores the number of votes each choice gets over multiple pages (probably using gm_setvalue although I'm open to other ideas.)</p>

348,022 | <p>I'm trying to implement a Load / Save function for a Windows Forms application.</p>
<p>I've got following components:</p>
<ul>
<li>A tree view</li>
<li>A couple of list views</li>
<li>A couple of text boxes</li>
<li>A couple of objects (which holds a big dictionarylist)</li>

<p>I want to implement a way to save all of this into a file, and resume/load it later on.</p>
<p>What's the best way to do this? </p>
<p>I think XML serialization is the way to go, but I'm not quite sure how, or where to start. Or will it require a really complex solution to be able to do this?</p>

348,109 | <p>Is hashing a password twice before storage any more or less secure than just hashing it once?</p>
<p>What I'm talking about is doing this:</p>
<pre><code>$hashed_password = hash(hash($plaintext_password));
</code></pre>
<p>instead of just this:</p>
<pre><code>$hashed_password = hash($plaintext_password);
</code></pre>
<p>If it is less secure, can you provide a good explanation (or a link to one)?</p>
<p>Also, does the hash function used make a difference? Does it make any difference if you mix md5 and sha1 (for example) instead of repeating the same hash function?</p>
<p>Note 1: When I say "double hashing" I'm talking about hashing a password twice in an attempt to make it more obscured. I'm not talking about the <a href="http://en.wikipedia.org/wiki/Double_hashing" rel="noreferrer">technique for resolving collisions</a>.</p>
<p><strong>Note 2: I know I need to add a random salt to really make it secure. The question is whether hashing twice with the same algorithm helps or hurts the hash.</strong></p>

<pre><code>LastTimeIDidTheLoop = new Date();

348,196 | <p>I'm trying to create a Python script that opens several databases and compares their contents. In the process of creating that script, I've run into a problem in creating a list whose contents are objects that I've created.</p>
<p>I've simplified the program to its bare bones for this posting. First I create a new class, create a new instance of it, assign it an attribute and then write it to a list. Then I assign a new value to the instance and again write it to a list... and again and again...</p>
<p>Problem is, it's always the same object so I'm really just changing the base object. When I read the list, I get a repeat of the same object over and over. </p>
<p>So how do you write objects to a list within a loop?</p>
<p>Here's my simplified code</p>
<pre><code>class SimpleClass(object):
pass
x = SimpleClass
# Then create an empty list
simpleList = []
#Then loop through from 0 to 3 adding an attribute to the instance 'x' of SimpleClass
for count in range(0,4):
# each iteration creates a slightly different attribute value, and then prints it to
# prove that step is working
# but the problem is, I'm always updating a reference to 'x' and what I want to add to
# simplelist is a new instance of x that contains the updated attribute
x.attr1= '*Bob* '* count
print "Loop Count: %s Attribute Value %s" % (count, x.attr1)
simpleList.append(x)
print '-'*20
# And here I print out each instance of the object stored in the list 'simpleList'
# and the problem surfaces. Every element of 'simpleList' contains the same attribute value
y = SimpleClass
print "Reading the attributes from the objects in the list"
for count in range(0,4):
y = simpleList[count]
print y.attr1
</code></pre>
<p>So how do I (append, extend, copy or whatever) the elements of simpleList so that each entry contains a different instance of the object instead of all pointing to the same one?</p>

348,236 | <p>I'm working on an AJAXy project (Dojo and Rails, if the particulars matter). There are several places where the user should be able to sort, group, and filter results. There are also places where a user fills out a short form and the resulting item gets added to a list on the same page.</p>
<p>The non-AJAXy implementation works fine -- the view layer server-side already knows how to render this stuff, so it can just do it again in a different order or with an extra element. This, however, adds lots of burden to the server.</p>
<p>So we switched to sending JSON from the server and doing lots of (re-)rendering client-side. The downside is that now we have duplicate code for rendering every page: once in Rails, which was built for this, and once in Dojo, which was not. The latter is basically just string concatenation.</p>
<p>So question part one: is there a good Javascript MVC framework we could use to make the rendering on the client-side more maintainable?</p>
<p>And question part two: is there a way to generate the client-side views in Javascript and the server-side views in ERB from the same template? I think that's what the Pragmatic Programmers would do.</p>
<p>Alternatively, question part three: am I completely missing another angle? Perhaps send JSON from the server but also include the HTML snippet as an attribute so the Javascript can do the filtering, sorting, etc. and then just insert the given fragment?</p>

348,256 | <p>I want to match a block of code <em>multiple</em> times in a file but can't work out the regular expression to do this. An example of the code block is:</p>
<pre><code>//@debug
...
// code in here
...
//@end-debug (possibly more comments here on same line)
</code></pre>
<p>Each code block I'm trying to match will start with <code>//@debug</code> and stop at the end of the line containing <code>//@end-debug</code></p>
<p>I have this at the moment:</p>
<pre><code>/(\/{2}\@debug)(.|\s)*(\/{2}\@end-debug).*/
</code></pre>
<p>But this matches one big block from the first <code>//@debug</code> all the way to end of the line of the very last <code>//@end-debug</code> in the file.</p>
<p>Any ideas?</p>

348,260 | <p>I am writing a Firefox extension. I would like to search the current webpage for a set of words, and count how many times each occurs. This activity is only performed when the user asks, but it must still happen reasonably quickly.</p>
<p>I am currently using indexOf on the BODY tag's innerHTML element, but am finding it too slow to run repeatedly in the following manner:</p>
<pre><code>function wordcount(doc, match)
{
var count = 0;
var pos = 0;
for(;;)
{
len=doc.indexOf(match, pos);
if(len == -1)
{
break;
}
pos = len + match.length;
count++;
}
return count;
}
var html = content.document.body.innerHTML.toLowerCase()
for(var i=0; i<keywords.length; i++)
{
var kw = keywords[i];
myDump(kw + ": " + wordcount(html, kw));
}
</code></pre>
<p>With 100 keywords, this takes approximately 10 to 20 seconds to run. There is some scope to reduce the number of keywords, but it will still need to run much quicker.</p>
<p>Is there a more obvious way to do this? What is the most efficient method? I have some ideas, but am reluctant to code each up without some idea of the performance I can expect:</p>
<ul>
<li>Navigate the DOM rather than using
innerHTML. Will this be likely
quicker or slower? It would have the
benefit of only searching textual
content.</li>
<li>Loop through the document word by
word, accumulating a count of each
word's occurence simultaneously.
With this method I would have to do
a bit more work parsing the HTML.</li>
</ul>
<p><em>Edit: Turns out that the slowest part was the myDump function writing to the error console. Duh! Nevertheless, there some interesting more efficient alternatives have been presented, which I am intending to use.</em></p>

348,266 | <p>I'm writing a basic planet viewer OpenGL Perl application, just for fun.
I have the basics working, with the glorious planet, implemented through a <code>gluSphere()</code>, rotating with the classic earth texture map applied.</p>
<p>Now, what if I want to apply a second texture map through OpenGL (say, the "earth clouds")?</p>
<p>Of course, I can mix the two texture maps myself in PhotoShop or some other graphic application, but is there a way through OpenGL API?</p>
<p>I tried loading the two textures and generating the mipmaps but the planet is shown with only the first texture applied, not the second.</p>

348,268 | <p>I have a procedure that is run for a lot of items, skipping over certain items who don't meet a criterion. However, I then go back and run it for some of the individuals who were missed in the first pass. I currently do this by manually re-running the procedure for each individual person, but would ideally like a solution a little more hands off.</p>
<p>Something my boss suggested might be effective would be creating a List (as in Data -> Lists) that contains the names of the items in question, and then iterating over the list. Sadly, my help-file fu seems to be failing me - I don't know whether I just don't know what to look for, or what.</p>
<p>Running the "Generate Macro" command shows that the VBA to create a list in the first place is along the lines of
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$1"), , xlYes).Name = "List1"</p>
<p>Unfortunately, I can't seem to figure out how to then do stuff with the resulting list. I'm looking to making a loop along the lines of</p>
<pre><code>For Each ListItem in List
Run the procedure on the text in ListItem.Value
Next ListItem
</code></pre>
<p>Any suggestions?</p>

348,282 | <p>I'm working on a site with multiple subdomains, some of which should get their own session.</p>
<p>I think I've got it worked out, but have noticed something about cookie handling that I don't understand. I don't see anything in the docs that explains it, so thought I would see if anyone here has some light to shed on the question.</p>
<p>If I just do:</p>
<pre><code>session_start();
</code></pre>
<p>I end up with a session cookie like this:</p>
<p>subdomain.example.net</p>
<p>However, if I make any attempt to set the cookie domain myself, either like</p>
<pre><code>ini_set('session.cookie_domain', 'subdomain.example.net');
</code></pre>
<p>or like</p>
<pre><code>session_set_cookie_params( 0, "/", "subdomain.example.net", false, false);
</code></pre>
<p>I end up with a cookie for .subdomain.example.net (note the opening dot), which I believe means "match all subdomains (or in this case sub-subdomains).</p>
<p>This seems to happen with all my cookies actually, not just session. If I set the cookie domain myself, it automatically has the dot prepended, meaning this domain and all subs of it. If I don't set the domain, then it gets it right by using only the current domain.</p>
<p>Any idea what causes this, and what I can do to control that prepending dot?</p>
<p>Thanks!</p>

348,304 | <p>I am developing a State Machine Workflow using C# and WF in visual studio 2008. On one of my states I need to wait for multiple events to happen until the workflow can transition to the next state. As an example think of a unanimous voting scenario. I cannot find a way to do this. Does anyone have a solution or workaround for this problem? </p>

348,305 | <p>I have a program that needs to do a <strong>compile time checkable</strong> map from one known set of values to another known set of values:</p>
<pre>
in out
------------
8 37
10 61
12 92
13 1/4 109
15 1/4 151
etc
</pre>
<p>This would be easy if the inputs were either integers or evenly spaced. I'm going to be iterating over the rows but also want to be able to do lookups in a readable manor.</p>
<p>My current thought (that I'm not liking) is to define an enum like</p>
<pre><code>enum Size
{
_8,
_10,
_12,
_13_25,
_15_25,
// etc
}
</code></pre>
<p>and then set it up for 2 lookups.</p>
<p>Any better ideas?</p>
<p><strong>Edit:</strong> My primary concern is limiting what I can <em>try</em> to look up. I'd like stuff to <em>not even compile</em> if the code might try and look up something that is invalid.</p>
<p>The set is small and iteration times are almost totally irrelevant. </p>
<p>I haven't seen anything that gains me anything over the enum so for now I'm going with that. OTOH I'll keep watching this question.</p>
<p><code>*</code> Note: I'm not worried about catching issues with pointers and what not, just straight forward code like for loops and variable assignments.</p>
<hr>
<p><strong>The nitty grity</strong>: I over simplified the above for clarity and generality. I actually have a table that has 3 non-integer, non-uniform axes and one non-numeric axis. And at this point I'm not sure what directions I'm going to need to enumerate it in.</p>
<p>a few links to give a flavor of what I'm looking for:</p>
<p><a href="http://www.boost.org/doc/libs/1_37_0/boost/units/systems/si.hpp" rel="nofollow noreferrer">Boost::SI</a> and my <a href="http://www.dsource.org/projects/scrapple/browser/trunk/units" rel="nofollow noreferrer">D version</a> of <a href="http://www.dsource.org/projects/scrapple/browser/trunk/units/constants.d" rel="nofollow noreferrer">the</a> same <a href="http://www.dsource.org/projects/scrapple/browser/trunk/units/types.d" rel="nofollow noreferrer">idea</a></p>
