357,323 | <p>I have a page that renders slowly. The trip across the net is quick. The initial load of the page is quick. You can actually see (if your machine is slow enough), the initial layout of the html components. Then some javascript stuff runs, making some of those components all ajaxy. Then finally the css gets applied.</p>
<p>I can't do anything about the javascript that's slowing everything to a crawl. So I need a throbber to tell the user to hold up, the browser is working. Is there any way to trap the browser is done rendering event? Is there even such an event? Is there another way to do this?</p>

357,328 | <p>I have four tables (A,B,C,D) where A is the parent of one to many relationships with B and C. C and D are parents to a one to many relationship with table D. Conceptually, the primary keys of these tables could be:</p>
<ul>
<li>A: Aid </li>
<li>B: Aid, bnum (with foreign key to A)</li>
<li>C: Aid, cnum (with foreign key to A)</li>
<li>D: Aid, bnum, cnum (with foreign keys to B and C)</li>
</ul>
<p>Where the 'num' columns auto increment based on each parent id in the relationship rather then on each record. I used this approach on a previous application, and it was not an issue since the creation of B and C records was done by a sequential process by generating a new 'num' value via a 'select max()' query. I was never really satisfied with the approach, but it got the job done. </p>
<p>For the specific case I am working on now, records in tables A and B are entered by users so auto-generation of id's is not an issue. In the case of tables C and D, records in these tables are being generated by multiple concurrent batch processes so their identifiers will need to be generated some how. The previous method I listed will not work do to the race condition. </p>
<p>Note that this is for an Oracle database so I will be using sequences and not auto-increment columns.</p>
<p>Given the constraints above, how you would you design tables to represent A,B,C, and D so that the relationships between the entities are properly enforced AND application code would not be required to generate any identifiers?</p>

357,353 | <p>What happens when I do the following?</p>
<pre><code>(define ((func x) y)
(if (zero? y)
((func x) 1)
12))
</code></pre>
<p>I understand that I can do this:</p>
<pre><code>(define curried (func 5))
</code></pre>
<p>And now I can use curried. What I'm curious about is in the definition of the function. Does the line</p>
<pre><code>((func x) 1)
</code></pre>
<p>create a new lambda with x as the argument, and then invoke it on 1? Or is it smarter than that and it just re-uses the existing one. (For example, if I do <code>(curried 0)</code>, the <code>((func x) 1)</code> line would be equivalent to <code>(curried 1)</code> - does PLAI Scheme do this?)</p>

357,364 | <p>Is a string actually a character array (is-a), or does it have a character array as an internal store (has-a), or is it's own object which can expose itself as a with an array of characters?</p>
<p>I am more inclined to say it is it's own object, but then why are we so inclined to always say "A string is an array of characters..."? </p>

357,370 | <p>I would like to store my FreeMarker templates in a database table that looks something like:</p>
<pre><code>template_name | template_content
---------------------------------
hello |Hello ${user}
goodbye |So long ${user}
</code></pre>
<p>When a request is received for a template with a particular name, this should cause a query to be executed, which loads the relevant template content. This template content, together with the data model (the value of the 'user' variable in the examples above), should then be passed to FreeMarker.</p>
<p>However, the <a href="http://freemarker.sourceforge.net/docs/api/index.html" rel="noreferrer">FreeMarker API</a> seems to assume that each template name corresponds to a file of the same name within a particular directory of the filesystem. Is there any way I can easily have my templates loaded from the DB instead of the filesystem?</p>
<p><strong>EDIT:</strong> I should have mentioned that I would like to be able to add templates to the database while the application is running, so I can't simply load all templates at startup into a new StringTemplateLoader (as suggested below).</p>

357,388 | <p>I would class myself as a typical small developer/independant designer and I recently purchased some new hardware for the office and thought I better organise myself better than I have in the past.</p>
<p>So I am wondering how you all organise all your files etc so that you can find them easily enough, and relate them together.</p>
<p>Currently I have a webserver running on the desktop, and I have a folders called Projects, closed projects, etc and these each contain a folder with the client/website name and it contains their web folders structure. But what do you do with all the other files, typically I receive PSD's, zip files with CSS layouts, images, content documentation, emails, logos, specs, project documentation, PDFs to upload to the site etc.</p>
<p>Do you use another single folder (my documents) with a client name for each or is there a better way to keep control of all your client folders.</p>
<p>This is aimed particularly at programmers who get lots of information/resources from clients/managers and so I think its an important programming question on how you set yourself up, because a clean setup results in better coding. </p>

357,396 | <p>I have two classes: Media and Container.</p>
<p>I have two lists <code>List<Media></code> and <code>List<Container></code></p>
<p>I'm passing these lists to another function (one at a time);</p>
<p>it can be one or another; </p>
<p>what's the proper way to check for the "template" type of the list so i can call an asssociated method depending on the list type?</p>
<p>or should i just try casting to the List<> and put Try/Catch blocks around it ?</p>
<pre><code> Object tagObj = mediaFlow1.BackButton.Tag;
if (tagObj == Media)
//do this
else if (tagObj == Container)
//do this
else
throw new Exception("Not a recognized type");
</code></pre>

357,404 | <p>I just joined a new C++ software project and I'm trying to understand the design. The project makes frequent use of unnamed namespaces. For example, something like this may occur in a class definition file:</p>
<pre><code>// newusertype.cc
namespace {
const int SIZE_OF_ARRAY_X;
const int SIZE_OF_ARRAY_Y;
bool getState(userType*,otherUserType*);
}
newusertype::newusertype(...) {...
</code></pre>
<p>What are the design considerations that might cause one to use an unnamed namespace? What are the advantages and disadvantages?</p>

357,415 | <p>I'm sure this is really simple if you know anything about binary files, but I'm a newbie on that score.</p>
<p>How would I extract the data from NASA .hgt files? Here is a description from www2.jpl.nasa.gov/srtm/faq.html:</p>
<blockquote>
<p><b>The SRTM data files have names like "N34W119.hgt". What do the
letters and numbers refer to, and what is ".hgt" format?</b></p>
<p>Each data file covers a one-degree-of-latitude by one-degree-of-longitude
block of Earth's surface. The first seven characters indicate the southwest
corner of the block, with N, S, E, and W referring to north, south, east,
and west. Thus, the "N34W119.hgt" file covers latitudes 34 to 35 North and
longitudes 118-119 West (this file includes downtown Los Angeles,
California). The filename extension ".hgt" simply stands for the word
"height", meaning elevation. It is NOT a format type. These files are
in "raw" format (no headers and not compressed), 16-bit signed integers,
elevation measured in meters above sea level, in a "geographic" (latitude
and longitude array) projection, with data voids indicated by -32768.
International 3-arc-second files have 1201 columns and 1201 rows of data,
with a total filesize of 2,884,802 bytes ( = 1201 x 1201 x 2). United
States 1-arc-second files have 3601 columns and 3601 rows of data, with a
total filesize of 25,934,402 bytes ( = 3601 x 3601 x 2). For more
information read the text file "SRTM_Topo.txt" at
http://edcftp.cr.usgs.gov/pub/data/srtm/Readme.html</p>
</blockquote>
<p>Thanks for any help! I am going to use this data in a python script, so if you could not use any language-specific tricks for any other languages, that would be awesome.</p>

357,447 | <p>I think the direct answer to the question is 'No' but I'm hoping that someone has written a real simple library to do this (or I can do it...ugh...)</p>
<p>Let me demonstrate what I am looking for with an example.
Suppose I had the following:</p>
<pre><code>class Person {
string Name {get; set;}
int NumberOfCats {get; set;}
DateTime TimeTheyWillDie {get; set;}
}
</code></pre>
<p>I would like to be able to do something like this:</p>
<pre><code>static void Main() {
var p1 = new Person() {Name="John", NumberOfCats=0, TimeTheyWillDie=DateTime.Today};
var p2 = new Person() {Name="Mary", NumberOfCats=50, TimeTheyWIllDie=DateTime.Max};
var str = String.Format(
"{0:Name} has {0:NumberOfCats} cats and {1:Name} has {1:NumberOfCats} cats. They will die {0:TimeTheyWillDie} and {1:TimeTheyWillDie} respectively
", p1, p2);
Console.WriteLine(str);
}
</code></pre>
<p>Does anyone know if theres a format for doing something like this or if someone has written a library to do it? I know it shouldn't be too hard, but I'd rather not be reimplementing the wheel.</p>

357,461 | <p>Does anyone know of any eclipe plugin that lets you easily change and use file encodings? I sometimes need to edit template files to do small tweaks, but the files are sometimes ISO, sometimes UTF8, sometimes others, so using eclipse for this leads to disaster :)</p>

357,465 | <p>Is there a way where I can add a connection string to the ConnectionStringCollection returned by the ConfigurationManager at runtime in an Asp.Net application?</p>
<p>I have tried the following but am told that the configuration file is readonly.</p>
<pre><code>ConfigurationManager.ConnectionStrings.Add(new ConnectionStringSettings(params));
</code></pre>
<p>Is there another way to do this at runtime? I know at design time I can add a connection string to the web.config; however, I'm looking to add something to that collection at run time.</p>
<p>Thanks</p>
<p>EDIT:
One of the reasons why I'm attempting to do this is due to a security requirement that prevents me from placing ConnectionStrings in the web.config (even encrypted). I would like to use elements like Membership and Profiles on my project; however, I am looking into an alternative to doing such w/o writing a custom provider. Custom Provider's aren't all that bad, but if I can find an easier solution, I'm all for it.</p>

357,470 | <p>I am in charge of providing a theme functionality for a site using a big CSS file (thousands of elements) I've just inherited.
Basically we want to allow the user to be able to change the colors on the screen.</p>
<p>Every CSS element, besides color definition also have lots of other attributes - size, font, float, etc... As well a specific color appears in various CSS elements.</p>
<p>If I use the Theme functionality of ASP.NET to have a different CSS file per theme, I have to duplicate my CSS file across all the themes, and it becomes a maintenance nightmare. </p>
<p>Optimally I would like to have a single CSS file (for maintenance) and be able to change the color attributes only.</p>
<p>What are the options here?</p>

<p>inputFile.getline(myArray, [10][10], '\n');</p>
<p>but it doesn't like having the string length in square brackets it seems, what should I do?</p>

357,491 | <p>I would like to verify that an app I am writing is running on an iPhone. What would be
perfect is this: Apple baked an SSL client certificate into each iphone which can be authenticated by a receiving server. I this the case?</p>
<p>I have not started researching this yet, I will update with anything I find.</p>
<p>UPDATE:
<a href="http://developer.apple.com/DOCUMENTATION/Security/Conceptual/SecureCodingGuide/Articles/SecuritySvcs.html" rel="nofollow noreferrer">Here</a> is some Apple documentation on certificates and keychains. So:</p>
<blockquote>
<p>In iPhone OS, Keychain Services checks an application’s signature before giving it access to a keychain, and lets an application have access only to its own keychain items (with the possible exception of items for which the application has obtained persistent references).
In iPhone OS, the user is never asked to authenticate and no Keychain Access utility is provided by Apple.</p>

357,505 | <p>I have a web forum that I have coded in Python for the App Engine platform. I have noticed that it is not being indexed well by Google and I am trying to fix that.<br>
I have used Google Webmaster to submit a sitemap with almost 400 URLs but apparently only 8 were indexed!<br>
I even get a warning stating:</p>
<blockquote>
<p>All the URLs in your Sitemap are marked as having dynamic content (the value of is "always"). Because dynamic content is difficult for search engines to crawl and index, this may impact your site's performance in search results. Check your Sitemap to make sure your site information is correct.</p>
</blockquote>
<p>One thing I am considering is the way my URLs are formed. Almost all URLs use arguments and I allocate each post, thread, forum, user etc... an ID.</p>
<p>So for example one of my forums is:</p>
<p><a href="http://silicon.appspot.com/readforum?id=2075" rel="nofollow noreferrer">http://silicon.appspot.com/readforum?id=2075</a></p>
<p>Where the forum's ID is 2075. I have heard this is bad practice so I am considering changing this but I am not sure whether it will make any difference. Could someone give me some hints in relation to how to get Google to index my <em>entire</em> site?</p>

357,560 | <p>I have potentially large files that need to be sorted by 1-n keys. Some of these keys might be numeric and some of them might not be. This is a fixed-width columnar file so there are no delimiters.</p>
<p>Is there a good way to do this with Unix sort? With one key it is as simple as using '-n'. I have read the man page and searched Google briefly, but didn't find a good example. How would I go about accomplishing this?</p>
<p>Note: I have ruled out Perl because of the file size potential. It would be a last resort.</p>

357,571 | <p>the object of the game in this case is to use a Treeview with a sitemap provider - and implement using CSS. I'm guessing the way to do this is with the CSS adapter kit. </p>
<p>I've plugged in the adapters using the DLL implementation and there i get my basic treeview but it seems to pull in all sorts of js that lets me click on nodes and such. In my case I just want to display a hierarchy with nested UL and LI's. I dont want any js clicky clicky!! </p>
<p>Is there anyway to accomplish this without having to use a seperate adapter project and rewriting the code to transform/render the treeview?</p>
<p>I'm also open to other options with the goal being a simple hierarchy on a treeview/menu, and a breadcrumb, coming out of an XML file.</p>
<p>thanks!</p>

357,578 | <p>I want to add a single model object that has been instantiated <em>once</em> in XAML, and add it to two different collections (in xaml).</p>
<p>The following code renders fine in Blend's Design Time, but I get the following errors at run time:</p>
<p><em>For "Post1"</em><br>
Object of type 'WpfBlog.Models.Tag' cannot be converted to type 'System.Collections.ObjectModel.ObservableCollection`1[WpfBlog.Models.Tag]'. Error at object 'WpfBlog.Admin' in markup file 'WpfBlog;component/Admin.xaml' Line XX Position YY.</p>
<p><em>If I comment out "Post1", I'll get this error on "Post2"</em><br>
Cannot add element to property 'Tags', because the property can have only one child element if it uses an explicit collection tag. Error at object 'System.Windows.StaticResourceExtension' in markup file 'WpfBlog;component/Admin.xaml' Line AA Position BB.</p>
<pre><code><Window.Resources>
<model:Tag x:Key="TDD" Name="TDD" ForeColor="Black" BackColor="White" />
<model:Tag x:Key="Agile" Name="Agile" ForeColor="White" BackColor="Black" />
<model:Tag x:Key="Waterfail" Name="Waterfail" ForeColor="Red" BackColor="White" />
</Window.Resources>
<Window.DataContext>
<local:AdminViewModel>
<local:AdminViewModel.AllTags>
<StaticResource ResourceKey="TDD"/>
<StaticResource ResourceKey="Agile"/>
<StaticResource ResourceKey="Waterfail"/>
</local:AdminViewModel.AllTags>

</code></pre>
<p>The following code compiles and runs fine, but two tags named "TDD" get created, so if I try to rename the tag, I have to do it for all of the posts, instead of just the one Tag object.</p>
<pre><code><Window.Resources>
<model:Tag x:Key="TDD" Name="TDD" ForeColor="Black" BackColor="White" />
<model:Tag x:Key="Agile" Name="Agile" ForeColor="White" BackColor="Black" />

<StaticResource ResourceKey="Agile"/>
<StaticResource ResourceKey="Waterfail"/>

<local:AdminViewModel.Posts>
<local:PostViewModel Title="Post1">
<local:PostViewModel.Tags>
<model:Tag Name="TDD" ForeColor="Black" BackColor="White" />
</local:PostViewModel.Tags>
</local:PostViewModel>
<local:PostViewModel Title="Post2">

</local:PostViewModel.Tags>
</local:PostViewModel>
</local:AdminViewModel.Posts>
</local:AdminViewModel>
<Window.DataContext>
</code></pre>
<p>Any ideas? I'd be able to ignore it and work around it if Blend didn't render it correctly, but it does!</p>

357,593 | <p>How come the iPhone Interface Builder doesn't let me set the X,Y coordinates of a top-level UIView? (Meaning, a view whose direct parent is a UIViewController.) The X and Y boxes on the View Size tab are grayed out. I can change the X,Y values in code at runtime, so why not in the Interface Builder?</p>
<p>Thanks.</p>

357,600 | <p>I can't find much information on <code>const_cast</code>. The only info I could find (on Stack Overflow) is:</p>
<blockquote>
<p>The <code>const_cast<>()</code> is used to add/remove const(ness) (or volatile-ness) of a variable.</p>
</blockquote>
<p>This makes me nervous. Could using a <code>const_cast</code> cause unexpected behavior? If so, what?</p>
<p>Alternatively, when is it okay to use <code>const_cast</code>?</p>

357,639 | <p>I'm trying to write a script that will create a file on the server then use <code>header()</code> to redirect the user to that file. Then, after about 10 seconds I want to delete the file. I've tried this:</p>
<pre><code>header('Location: '.$url);
flush();
sleep(10);
unlink($url);
</code></pre>
<p>But the browser just waits for the script to complete then gets redirected, but the file hes been deleted by that time. Is there someway to tell the browser "end of file", then keep computing? Or maybe have PHP start another script, but not wait for that script to finish?</p>

357,643 | <h2>Repetitive Dates:</h2>
<p>Billing cycles come in a lot of different formats, for example: "the first of the month", "third Friday of the month", or "first weekday on or after 21st day after the 13th of the month" (thanks visa!). My goal is to be able to represent these different billing cycles in one easily parsed database text field. </p>

357,648 | <p>I use Intellij Idea 7 for Java dev. My dev is 'limited' to all J2SE features plus light JSP, Servlets, and super light usage of JPA. No J2EE, no massive use of random frameworks, etc.</p>
<p>Is it worth upgrading to ver 8? "Worth it" to me means better "core functionality" in terms of speed (ESPECIALLY startup speed), memory utilization (seems like it starts having serious problems with four or more projects open), and auto bug-finding.
More frameworks supported and more languages supported (other than perhaps Haskell and C++), and more refactorings don't interest me at this time.</p>
<p>A while back, I installed a preview version of 8 and it seemed -exactly- the same as 7, as far as my needs were concerned.</p>
<p>Anyone loving the upgrade to 8, and if so, why?</p>
<p>Thanks</p>

357,656 | <p>(I'm using the <a href="http://developer.berlios.de/projects/pyprocessing" rel="nofollow noreferrer">pyprocessing</a> module in this example, but replacing processing with multiprocessing should probably work if you run <a href="http://docs.python.org/library/multiprocessing.html" rel="nofollow noreferrer">python 2.6</a> or use the <a href="http://code.google.com/p/python-multiprocessing/" rel="nofollow noreferrer">multiprocessing backport</a>)</p>
<p>I currently have a program that listens to a unix socket (using a processing.connection.Listener), accept connections and spawns a thread handling the request. At a certain point I want to quit the process gracefully, but since the accept()-call is blocking and I see no way of cancelling it in a nice way. I have one way that works here (OS X) at least, setting a signal handler and signalling the process from another thread like so:</p>
<pre><code>import processing
from processing.connection import Listener
import threading
import time
import os
import signal
import socket
import errno
# This is actually called by the connection handler.
def closeme():
time.sleep(1)
print 'Closing socket...'
listener.close()
os.kill(processing.currentProcess().getPid(), signal.SIGPIPE)
oldsig = signal.signal(signal.SIGPIPE, lambda s, f: None)
listener = Listener('/tmp/asdf', 'AF_UNIX')
# This is a thread that handles one already accepted connection, left out for brevity
threading.Thread(target=closeme).start()
print 'Accepting...'
try:
listener.accept()
except socket.error, e:
if e.args[0] != errno.EINTR:
raise
# Cleanup here...
print 'Done...'
</code></pre>
<p>The only other way I've thought about is reaching deep into the connection (listener._listener._socket) and setting the non-blocking option...but that probably has some side effects and is generally really scary.</p>
<p>Does anyone have a more elegant (and perhaps even correct!) way of accomplishing this? It needs to be portable to OS X, Linux and BSD, but Windows portability etc is not necessary.</p>
<p><strong>Clarification</strong>:
Thanks all! As usual, ambiguities in my original question are revealed :)</p>
<ul>
<li>I need to perform cleanup after I have cancelled the listening, and I don't always want to actually exit that process.</li>
<li>I need to be able to access this process from other processes not spawned from the same parent, which makes Queues unwieldy</li>
<li>The reasons for threads are that:
<ul>
<li>They access a shared state. Actually more or less a common in-memory database, so I suppose it could be done differently.</li>
<li>I must be able to have several connections accepted at the same time, but the actual threads are blocking for something most of the time. Each accepted connection spawns a new thread; this in order to not block all clients on I/O ops.</li>
</ul></li>
</ul>
<p>Regarding threads vs. processes, I use threads for making my blocking ops non-blocking and processes to enable multiprocessing.</p>

357,672 | <p>I want to dynamically create variables with dynamic names for later use in my transform, but to do this I'd need to dynamically generate XSL and then run it in the same script.</p>
<p>This is just a rough pseudo code example of what I'm looking for.</p>
<pre><code> <xsl:for-each select="//constants/constant" >
<xsl:variable >
<xsl:attribute name="name">
<xsl:value-of select="@name"/>
</xsl:attribute>
<xsl:attribute name="select">
<xsl:value-of select="@value"/>
</xsl:attribute>
</xsl:variable>
</xsl:for-each>
</code></pre>
<p>Can I use XSL to dynamically build XSL to be run later in the same script?</p>
<p>Note: our XML is transformed via a batch process running a CL XSL transform engine; so just referencing an XSL stylesheet in the XSL document isn't an option.</p>

357,752 | <p>I have a web application that uses the current version of JQuery that needs to get some JSON objects back from a REST web service. I'm using the following call to $.getJSON:</p>
<p>$.getJSON("<a href="http://localhost:17245/Service.svc/?format=json" rel="nofollow noreferrer">http://localhost:17245/Service.svc/?format=json</a>", function(data) {alert(data.id);});</p>
<p>This call works fine in IE7 and I can call the service with no problem in Fiddler. I've stepped through this in Firebug, but when Firefox gets to this line the javascript execution just seems to "die" with no error, no call back, no nothing.</p>
<p>I've also used $.ajax and have the same issue; works fine in IE, nothing in Firefox.</p>
<p>Anyone have any ideas? I'm VERY new to JQuery, so please be gentle.</p>
<p>Thanks,
James</p>

357,803 | <p>Basically what I need is an automated way to update the product version number in WiX (3.0 with Votive etc), and then get that version number into an Inno Setup "bootstrapper"</p>
<p>I pretty much have the process mostly automated, however version numbers still need to be updated manually which obviously isn't ideal, but I couldn't find how to pass in values to Inno Setup at compile time (and how to reference them), and in the WiX project I need to know how to reference the version number of a different project in the same solution in Visual Studio 2008</p>

357,804 | <p>Today I found out that putting strings in a resource file will cause them to be treated as literals, i.e putting "Text for first line \n Text for second line" will cause the escape character itself to become escaped, and so what's stored is "Text for first line \n Text for second line" - and then these come out in the display, instead of my carriage returns and tabs</p>
<p>So what I'd like to do is use string.replace to turn <code>\\</code> into <code>\</code> - this doesn't seem to work.</p>
<pre>s.Replace("\\\\", "\\"); </pre>
<p>doesn't change the string at all because the string thinks there's only 1 backslash</p>
<pre>s.Replace("\\", "");</pre>
<p>replaces all the double quotes and leaves me with just n instead of \n</p>
<p>also, using <code>@</code> and half as many <code>\</code> chars or the <code>Regex.Replace</code> method give the same result</p>
<p>anyone know of a good way to do this without looping through character by character?</p>

357,810 | <p>I am a beginner of python and have a question, very confusing for me.
If I define a function first but within the function I have to use a variable which is defined in another function below, can I do it like this? Or how can I import the return things of another function into a function?
for example:</p>
<pre><code>def hello(x,y):
good=hi(iy,ix)
"then do somethings,and use the parameter'good'."
return something
def hi(iy,ix):
"code"
return good
</code></pre>

357,814 | <p>It seems that the choice to use string parsing vs. regular expressions comes up on a regular basis for me anytime a situation arises that I need part of a string, information about said string, etc.</p>
<p>The reason that this comes up is that we're evaluating a soap header's action, <strong>after</strong> it has been parsed into something manageable via the OperationContext object for WCF and <em>then</em> making decisions on that. Right now, the simple solution seems to be basic substring'ing to keep the implementation simple, but part of me wonders if RegEx would be better or more robust. The other part of me wonders if it'd be like using a shotgun to kill a fly in our particular scenario.</p>
<p>So I have to ask, what's the typical threshold that people use when trying to decide to use RegEx over typical string parsing. Note that I'm not very strong in Regular Expressions, and because of this, I try to shy away unless it's absolutely vital to avoid introducing more complication than I need.</p>
<p>If you couldn't tell by my choice of abbreviations, this is in .NET land (C#), but I believe that doesn't have much bearing on the question.</p>
<hr>
<p><strong>EDIT</strong>: It seems as per my typical Raybell charm, I've been too wordy or misleading in my question. I want to apologize. I was giving some background to help give clues as to what I was doing, not mislead people. </p>
<p>I'm basically looking for a guideline as to when to use substring, and variations thereof, over Regular Expressions and vice versa. And while some of the answers may have missed this (and again, my fault), I've genuinely appreciated them and up-voted as accordingly.</p>

357,822 | <p>This is more an observation than a real question: MS-Access (and VBA in general) is desperately missing a tool where error handling code can be generated automatically, and where the line number can be displayed when an error occurs. Did you find a solution? What is it? I just realized how many hundreds of hours I spared since I found the right answer to this basic problem a few years ago, and I'd like to see what are your ideas and solutions on this very important issue. </p>

357,864 | <p>What is the best way of handling trying to get data from a DataReader that has more than one column with the same name?</p>
<p>Because of the amount of work involved and because we don't want to lose support from a vendor by changing the stored procedures we are using to retrieve the data, I am trying to find another way to get access to a column that shows up more than once in a datareader without having to rewrite the stored procedures.</p>
<p>Any Ideas?</p>
<p>EDIT:
Ok, the function that actually populates from a datareader is used in multiple places so there is a possibility that the function can be called by different stored procedures. What I did was to do a GetName using the index to check if it is the correct column, and if it is, then pull its value.</p>

357,903 | <p>I am creating a script on the fly to ftp some files from a remote computer. I create a file which is then called from the command line with</p>
<pre><code>ftp -s:filename proxy
</code></pre>
<p>where filename is the file I just created. The file has code similar to the following:</p>
<pre><code>anonymous@ip address
username
prompt off
binary
cd c:\destination directory
mget c:\source directory\*.*
quit
</code></pre>
<p>That doesn't work. Neither does the following:</p>
<pre><code>anonymous@ip address
username
prompt off
binary
cd c:\source directory
mput c:\destination directory
quit
</code></pre>
<p>Obviously, I'm not so good at ftp. How, in what order, where in my file do I specify the place where I want the files to be put (destination directory, and also from where the ftp process is running), and where I want the files to come from (ip address computer which has files I want). Do I need to set the directory before starting the ftp process?</p>
<p>I'm running this in an SSIS package, and I'm not using the SSIS ftp task, because I don't want a failure if no files are found. If there's nothing there, that's cool. If there is something there, I want a copy.</p>
<p>(It was working in my development area, and now, when I'm trying to get files from a server that I truely have no access to except ftp, I'm not getting anything. See <a href="https://stackoverflow.com/questions/140850/the-best-way-for-a-ssis-ftp-task-to-not-fail-when-there-are-no-files-to-copy">How to avoid SSIS FTP task from failing when there are no files to download?</a> for an earlier, related question.)</p>
<p><strong>Update:</strong>
Both of the answers below, listing lcd and cd, are correct. However, my example still failed, until I replaced the backslashes with forward slashes. In other words, my final, working result is as follows:</p>
<pre><code>anonymous@ip address
username
prompt off
binary
lcd /destination directory
cd /source directory
mget *.*
quit
</code></pre>

357,911 | <p>I have an application with several files that contain configuration parameters and other data that changes as the user uses the application. These files can change with newer versions of my software, but the user can also modify them (or they may be changed by the application itself). Basically, I'm looking for a solution to prevent the users' changes to these files from being overwritten but also a way to install the potentially updated files when the user upgrades my software. </p>
<p>With RPM on *NIX you could use the %config function to define a file as a configuration file and RPM would then rename the existing file (if it existed) and install the new one on an upgrade (maybe not ideal, but I could live with something like this for WiX).</p>
<p>I'd like to install my config files to a subdirectory or even a different name (e.g. default.cfg) and then use the <code><CopyFile></code> element in WiX to copy the files to their correct locations. This way, the default files would get removed on install and overwritten on an upgrade, but the actual user files would stay the same. Unfortunately with <code><CopyFile></code>, Windows Installer still wants to manage (and remove) the destination file.</p>
<p>I've also considered using the QtExec action in WixUtilExtension to basically do "copy default.cfg reallocation.cfg" but this wouldn't quite work and it is a bit of a hack.</p>
<p>What is the correct way to handle this?</p>

<p><strong><em>The Regex pattern is:</em></strong> <code>.*,\"<money>(.+,.+)\",?.*</code> </p>

357,963 | <p>I am developing a prototype for a game, and certain gameplay rules are to be defined in an ini file so that the game designers can tweak the game parameters without requiring help from me in addition to a re-compile. This is what I'm doing currently:</p>
<pre><code>std::ifstream stream;
stream.open("rules.ini");
if (!stream.is_open())
{
throw new std::exception("Rule file could not be opened");
}
// read file contents here
stream.close();
</code></pre>
<p>However, my stream never opens succesfully. Diving deep into the STL source during debugging reveals that _getstream() (as defined in stream.c) keeps on returning NULL, but I just can't figure out why this is. Help, anyone?</p>
<p>Edit: Rules.ini is in the same directory as the .exe file.</p>

<p>I am a beginner at Python, and I don't know how to fix the error. I am a little bit confused about <code>import "neighbours"</code> to <code>function "apply_rules"</code>, is that right way to do this?</p>

357,969 | <p>I am trying to combine some of my CSS and it is kind of an easy questions but I am kind of having some trouble, i have this code:</p>
<pre><code>h2.post-title, h2.post-title a{
display:block;
background-color:#000;
padding:3px;
color:#ffffff;
text-decoration:none;
text-transform:uppercase;
font:lighter 130% Georgia, Arial;
}
</code></pre>
<p>Do I need to have both of those selectors there? The only time I will be using the <code>h2.post-title</code> it will be a link. Any suggestions, I tried removing the first one, but it made it HUGE.</p>
<p>Thoughts?</p>

357,997 | <p>In Java you can define a new class inline using anonymous inner classes. This is useful when you need to rewrite only a single method of the class.</p>
<p>Suppose that you want create a subclass of <code>OptionParser</code> that overrides only a single method (for example <code>exit()</code>). In Java you can write something like this:</p>
<pre><code>new OptionParser () {
public void exit() {
// body of the method
}
};
</code></pre>
<p>This piece of code creates a anonymous class that extends <code>OptionParser</code> and override only the <code>exit()</code> method.</p>
<p>There is a similar idiom in Python? Which idiom is used in these circumstances?</p>

358,039 | <p>What is the meaning, and where is the Ruby documentation for the syntax of: </p>
<pre><code>Array(phrases)
</code></pre>
<p>which I found browsing the Rails source here:</p>
<pre><code># File actionpack/lib/action_view/helpers/text_helper.rb, line 109
...
119: match = Array(phrases).map { |p| Regexp.escape(p) }.join('|')
</code></pre>
<p>I thought that Array.new would normally be used to create an array, so something different must be going on here. BTW from the context around this code, the <code>phrases</code> variable can be either a string or an array of strings.</p>

358,048 | <p>I am using a third party application and would like to change one of its files. The file is stored in XML but with an invalid doctype.</p>
<p>When I try to read use a it errors out becuase the doctype contains "file:///ReportWiz.dtd"
(as shown, with quotes) and I get an exception for cannot find file. Is there a way to tell the docbuilder to ignore this? I have tried setValidate to false and setNamespaceAware to false for the DocumentBuilderFactory. </p>
<p>The only solutions I can think of are</p>
<ul>
<li>copy file line by line into a new file, omitting the offending line, doing what i need to do, then copying into another new file and inserting the offending line back in, or </li>
<li>doing mostly the same above but working with a FileStream of some sort (though I am not clear on how I could do this..help?)</li>

358,069 | <p>I just bought Visual Studio 2008 Professional and it came with SQL Server 2005 Developer Edition. I'm used to using SQL Server 2005 at work, but the Developer edition doesn't seem to come with Server Management Studio, so I'm at a bit of a loss. A few questions:</p>
<ol>
<li>What resources are there for configuring and setting up SQL Server 2005 Developer Edition?</li>
<li>What are some resources for managing databases (I know that I can have Multiple Databases with SQL Server 2005), and what 'extras' are provided by Developer Edition?</li>
<li>Are there any funky things I need to know about if I were to create a database and move it from Developer Edition to an actual deployment server?</li>
<li>Are there any other 'gotchas'?</li>
</ol>
<hr>
<p>Edit: I've answered the 'Why isn't SQL Server Management Studio showing up' question below. Resources for the other questions are still appreciated.</p>
<p>Any other insights?</p>

358,072 | <p>I have a javascript heavy app which has widgets like autocomplete dropdowns and tabs and so forth. Sometimes when dropdowns appear and disappear, or when you switch between tabs, it changes the height of the document. This can cause annoyances if the scrollbar appears and disappears rapidly, because it shifts the page. I would like to detect when a page changes its height, so I can fix the height to the maximum so far, so that if the scrollbar appears it won't disappear only a second later. Any suggestions?</p>
<p><em>Update: onresize won't work because that's for changes in the size of the viewport/window - I want changes in the length of the document. I hadn't known about the watch function, looks like it will work at least for FF, but IE doesn't support it.</em></p>

358,120 | <p>On Internet Explorer, the standard HTML file upload form also allows for direct input of the file name (instead of using the file selector dialog). This makes it possible to enter non-existing files. On other browsers (which do not let you do that) I suppose this case can still occur if you delete the file after having selected it.</p>
<p>In order to deal with bugs arising from this problem (like <a href="http://dev.fckeditor.net/ticket/2716" rel="nofollow noreferrer">this one</a>), I need to add some validation code on the server-side (which is only possible if the request actually goes to the server, of which I am not sure at this point), or on the client-side (which cannot be very straightforward, as you cannot access the actual file from the JavaScript sandbox). Other than that, the only (and possibly best) option seems to be to hide the input box with CSS magic, like GMail does for attachment files.</p>
<p>So, what happens when you try to upload a non-existing file?
Is there still a POST request being sent? Or will the browser abort, and if it does, how can I detect that?</p>

358,136 | <p>What is the most efficient way to remove duplicate items from an array under the constraint that axillary memory usage must be to a minimum, preferably small enough to not even require any heap allocations? Sorting seems like the obvious choice, but this is clearly not asymptotically efficient. Is there a better algorithm that can be done in place or close to in place? If sorting is the best choice, what kind of sort would be best for something like this?</p>

358,147 | <p>I have two computers. Both running WinXP SP2 (I don't really know ho similar they are beyond that). I am running MS Visual C# 2008 express edition on both and that's what I'm currently using to program.</p>
<p>I made an application that loads in an XML file and displays the contents in a DataGridView.</p>
<p>The first line of my xml file is:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
</code></pre>
<p>...and really... it's utf-8 (at least according to MS VS C# when I just open the file there).</p>
<p>I compile the code and run it on one computer, and the contents of my DataGridView appears normal. No funny characters. I compile the code and run it on the other computer (or just take the published version from computer #1 and install it on computer #2 - I tried this both ways) and in the datagridview, where there are line breaks/new lines in the xml file, I see funny square characters.</p>
<p>I'm a novice to encoding... so the only thing I really tried to troubleshoot was to use that same program to write the contents of my xml to a new xml file (but I'm actually writing it to a text file, with the xml tags in it) since the default writing to a text file seems to be utf-8. Then I read this new file back in to my program. I get the same results.</p>
<p>I don't know what else to do or how to troubleshoot this or what I might fundamentally be doing wrong in the first place.</p>

358,160 | <p>I've isolated the behaviour into the following test case. I'd be grateful to anyone who can tell me how to expect/verify a property set for a <code>List<T></code> property - it appears there's something going on inside <code>It.Is<T>(predicate)</code> that isn't making a whole lot of sense to me right now. Sample code will run as a console app from VS2008 - you'll need to add a reference to Moq 2.6 (I'm on 2.6.1014.1) - please try uncommenting the different ExpectSet statements to see what's happening...</p>
<pre><code>using System;
using Moq;
using System.Collections.Generic;
namespace MoqDemo {
public interface IView {
List<string> Names { get; set; }
}
public class Controller {
private IView view;
public Controller(IView view) {
this.view = view;
}
public void PopulateView() {
List<string> names = new List<string>() { "Hugh", "Pugh", "Barney McGrew" };
view.Names = names;
}
public class MyApp {
public static void Main() {
Mock<IView> mockView = new Mock<IView>();
// This works - and the expectation is verifiable.
mockView.ExpectSet(mv => mv.Names);
// None of the following can be verified.
// mockView.ExpectSet(mv => mv.Names, It.Is<Object>(o => o != null));
// mockView.ExpectSet(mv => mv.Names, It.Is<List<string>>(names => names.Count == 3));
// mockView.ExpectSet(mv => mv.Names, It.IsAny<IList<String>>());
Controller controller = new Controller(mockView.Object);
controller.PopulateView();
try {
mockView.VerifyAll();
Console.WriteLine("Verified OK!");
} catch (MockException ex) {
Console.WriteLine("Verification failed!");
Console.WriteLine(ex.Message);
}
Console.ReadKey(false);

358,168 | <p>Ok, I'm doing a bunch of RIA/AJAX stuff and need to create a "pretty", custom confirm box which is a DIV (not the built-in javascript confirm). I'm having trouble determining how to accomplish a pause in execution to give the user a chance to accept or decline the condition before either resuming or halting execution. (depending upon their answer) </p>
<p>So here's the general flow of logic I'm dealing with:</p>
<ol>
<li>User selects an item from dropdown and clicks button.</li>
<li>In client-side javascript eventhandler for button, I need to check a (this is the key) SERIES of conditions for the item they chose in dropdown. </li>
<li>These conditions could possibly result in not showing any confirmation at all or possibly only some of the conditions may evaluate to true which means I'll need to ask the user to accept or decline the condition before proceeding. Only one confirmation should be show at a time.</li>
</ol>
<p>To demonstrate the logic:</p>
<pre><code>function buttonEventHandler() {
if (condition1) {
if(!showConfirmForCondition1) // want execution to pause while waiting for user response.
return; // discontinue execution
}
if (condition2) {
if (!showConfirmForCondition2) // want execution to pause while waiting for user response.
return; // discontinue execution
}
if (condition3) {
if (!showConfirmForCondition3) // want execution to pause while waiting for user response.
return; // discontinue execution
}
...
}
</code></pre>
<p>If anybody has dealt with this challenge before and found a solution, help would be greatly appreciated. As a note, I'm also using the <b>MS Ajax</b> and <b>jQuery</b> libraries although I haven't found any functionality that may already be included in those for this problem.</p>

358,185 | <p><strong>Background:</strong><br>
I have an old web CMS that stored content in XML files, one XML file per page. I am in the process of importing content from that CMS into a new one, and I know I'm going to need to massage the existing XML in order for the import process to work properly.</p>
<p>Existing XML:</p>
<pre><code><page>
<audience1>true</audience>
<audience2>false</audience>
<audience3>true</audience>
<audience4>false</audience>
<audience5>true</audience>
</page>
</code></pre>
<p>Desired XML:</p>
<pre><code><page>
<audience1>true</audience>
<audience2>false</audience>
<audience3>true</audience>
<audience4>false</audience>
<audience5>true</audience>
<audiences>1,3,5</audiences>
</page>
</code></pre>
<p><strong>Question:</strong><br>
The desired XML adds the node, with a comma-delimited list of the other nodes that have a "true" value. I need to achieve the desired XML for several files, so what is the best way to accomplish this? Some of my ideas:</p>
<ul>
<li>Use a text editor with a regex find/replace. But what expression? I wouldn't even know where to begin.</li>
<li>Use a programming language like ASP.NET to parse the files and append the desired node. Again, not sure where to begin here as my .NET skills are only average.</li>
</ul>
<p>Suggestions?</p>

358,195 | <p>What's the best way to extract the key and value from a string like this:</p>
<pre><code>var myString = 'A1234=B1234';
</code></pre>
<p>I originally had something like this:</p>
<pre><code>myString.split('=');
</code></pre>
<p>And that works fine, BUT an equal (=) sign could be used as a key or value within the string plus the string could have quotes, like this:</p>
<pre><code>var myString = '"A123=1=2=3=4"="B1234"';
</code></pre>
<p>The string could also only have one pair of quotes and spaces:</p>
<pre><code>var myString = ' "A123=1=2=3=4" = B1234 ';
</code></pre>
<p>I'm not very good at regular expressions but I'm guessing that's the way forward?</p>
<p>What I want to end up with is two variables, key and value, in the case above, the key variable would end up being <em>A123=1=2=3=4</em> and the value variable would be <em>B1234</em>.</p>
<p>If there is no value present, for example if this were the original string:</p>
<pre><code>var myString = 'A1234';
</code></pre>
<p>Then I would want the key variable to be 'A1234' and for the value variable to be null or false - or something I can test against.</p>
<p>Any help is appreciated.</p>

358,196 | <p>I'm new to unit testing and I'm trying to figure out if I should start using more of <code>internal</code> access modifier. I know that if we use <code>internal</code> and set the assembly variable <code>InternalsVisibleTo</code>, we can test functions that we don't want to declare public from the testing project. This makes me think that I should just always use <code>internal</code> because at least each project (should?) have its own testing project. Can you guys tell me why I shouldn't do this? When should I use <code>private</code>?</p>

358,209 | <p>Greetings!</p>
<p>I have a DropDownList within a FormView which are bound to XmlDataSources:</p>
<pre><code><asp:FormView ID="MyFormView" runat="server" DataSourceID="MyXmlDataSource">
<ItemTemplate>
<h1><%# XPath("SomeNode")%></h1>
<asp:Label ID="MyLabel" runat="server" AssociatedControlID="MyDdl" Text='<%# XPath("SomeOtherNode")%>' />
<asp:DropDownList ID="MyDdl"
runat="server"
DataSourceID="MyDdlDataSource"
DataTextField="name"
DataValueField="value"
AutoPostBack="true"
OnSelectedIndexChanged="MyDdl_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
</asp:FormView>
<asp:XmlDataSource ID="MyXmlDataSource" runat="server" XPath="Root/MainSection" />
<asp:XmlDataSource ID="MyDdlDataSource" runat="server" XPath="Root/MainSection/Areas/*" />
</code></pre>
<p>In the page's codebehind, I have the following OnLoad() method as well as the method for getting the selected value dropdownlist during postback:</p>
<pre><code>private m_key;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
string xml_data;
if (!IsPostBack)
{
xml_data = GetMyXml(0); // default value
MyXmlDataSource.Data = xml_data;
MyDdlDataSource.Data = xml_data;
}
else
{
GetSelections();
xml_data = GetMyXml(m_key);
MyXmlDataSource.Data = xml_data;
MyXmlDataSource.DataBind();
}
}
private void GetSelections()
{
DropDownList l_MyDdl = FindMyControl<DropDownList>("MyDdl");
if (l_MyDdl != null)
if (!Int32.TryParse(l_MyDdl.SelectedItem.Value, out m_key))
m_key = 0;
}
</code></pre>
<p>Everything works great, up until a postback as a result of the dropdown list changing occurs. When this happens, I get the value of the selected item in the dropdown list, pass it to my GetMyXml() method with the value from the dropdown list as a parameter and then set the FormView's datasource to the newly returned XML data from GetMyXml(). I've looked at the value of "xml_data" during postback and it's definitely correct. However, the values displayed on the page the FormView (like XPath("SomeNode")) are the values from before the postback happened and not the ones returned in xml_data. Why would this happen and how would I go about resolving it? Thanks in advance.</p>

358,220 | <p>Just flicking through one of my favourite books (Ellen Ullman's The Bug) and there is a small bit where one programmer confronts another over three levels of indirection:</p>
<pre><code>***object_array = ***winarray;
</code></pre>
<p>I get the idea of double indirection - a way of passing a pointer into a function, and allowing it to point to an object created within the function.</p>
<p>But have you come across any reason to use three (or more) levels of indirection?</p>

358,240 | <p>Is there anything better than a <a href="http://en.wikipedia.org/wiki/Trie" rel="nofollow noreferrer">Trie</a> for this situation?</p>
<ul>
<li>Storing a list of ~100k English words</li>
<li>Needs to use minimal memory</li>
<li>Lookups need to be reasonable, but don't have to be lightning fast</li>
</ul>
<p>I'm working with Java, so my first attempt was to just use a Set<String>. However, I'm targeting a mobile device and already running low on memory. Since many English words share common prefixes, a trie seems like a decent bet to save some memory -- anyone know some other good options?</p>
<p>EDIT - More info - The data structure will be used for two operations</p>
<ul>
<li>Answering: Is some word XYZ in the list?</li>
<li>Generating the neighborhood of words around XYZ with one letter different</li>
</ul>
<p>Thanks for the good suggestions</p>

358,251 | <p>I have made a C# application and I am trying to figure out if I can tap into build events of cctray (cruise control tray)? I don't want to re-invent the wheel, I just want to know when my builds fail or succeed (on a client machine) so than my custom C# application may execute a specific set of routines.</p>

358,263 | <p>I have a website where all requests are redirected silently (via <code>.htaccess</code>) to <code>index.php</code> and then PHP is used to show the correct page (by parsing the <code>REQUEST_URI</code>).</p>
<p>I was wondering if it's possible to submit POST data to a fake address too?</p>
<p>I've currently got my form like so...</p>
<pre><code><form action="/send-mail" method="post">
</code></pre>
<p>And my <code>.htaccess</code> rule is...</p>
<pre><code># redirect mail posting to index
RewriteRule send-mail index.php?send-mail [NC,L]
</code></pre>
<p>My <code>index.php</code> checks <code>isset($_GET['send-mail'])</code> which works fine.</p>
<p>This however seems to drop off all the POST data that should be sent to it.</p>
<p>Is there a way to keep the post data? I don't want to use GET because it can't send as much information, though it might not be an issue with a simple inquiry form.</p>
<p>Here is my <code>.htaccess</code> for redirecting to <code>index.php</code></p>
<pre><code># serve files and dirs if they exist please, otherwise send to index
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php
</code></pre>

358,344 | <p>I was reading the great article about binding and unbinding events (because I am a js beginner using jQuery) on <a href="http://www.learningjquery.com/2008/05/working-with-events-part-2" rel="nofollow noreferrer">Karl Swedberg's blog</a>, and I became totally puzzled at this part of the code (simplified for brevity):</p>
<pre><code> function addItemUnbind() {
$Add a button but it won't have it's event added;
addItemUnbind();
});
</code></pre>
<p>Why is it that by putting the same function within itself it doesn't keep executing into an infinite loop? However, it is used to re-bind the event to the element...!?</p>

358,347 | <p>I'm writing some Java code that uses a FileReader to load data from a few input files. I'm using TDD pretty heavily, and I'd like to add some tests that ensure that I'm cleaning up properly by calling close() on the reader when I'm done with it. Unfortunately, I can't come up with a good way to test for this. Anyone have any insights?</p>
<p>Edited to add: I know I can test explicitly for the close call using mock objects, but I'd like to avoid it if possible, partly because I find they lead to somewhat brittler code, and partly because I'm curious whether it's possible to write code that can recognize the effects of not closing a file.)</p>
