<p>I'd like to do something like this</p>
<blockquote>
<pre><code>raiserror(concat('Error in case @isFishy =', @isFishy, ' @isSmarmy=', @isSmarmy, ' @isTasty = ', @isTasty), 10, 1)
--or
raiserror('Error in case @isFishy =' + @isFishy + ' @isSmarmy=' + @isSmarmy + ' @isTasty = ' + @isTasty, 10, 1)
</code></pre>
</blockquote>
<p>But it just isn't working. How do I accomplish this? I'm in SQL Server 2005.</p>

<p>I know how to find out the current domain name in PHP already, the problem is when I put this code into a file and then include it from another server it shows the domain name of where the file is located. Is there any way for it to find out the domain or the site containing the include() code?</p>

<p>I have one user who gets an error message when he closes his browser. This only happens when he has visited a page which contains my applet. It seems to have been registered as a bug at Sun but that was many years ago. He is using Java 1.6 and IE7.</p>
<p>Has anyone seen this before and know a solution or work-around?</p>

<p>I'm trying to decode a WBXML encoded SyncML message from a Nokia N95.
My first attempt was to use the python pywbxml module which wraps calls to libwbxml. Decoding the message with this gave a lot of <unknown> tags and a big chunk of binary within a <Collection> tag. I tried running the contents of the <Collection> through by itself but it failed. Is there something I'm missing?</p>
<p>Also, does anyone know of a pure python implementation of a wbxml parser? Failing that a command line or online tool to decode these messages would be useful -- it would make it a lot easier for me to write my own...</p>

<p>In eclipse 3.4 I'm trying to do some performance tests on a large product, one of the included libraries is the vecmath.jar (javax.vecmath package) from the Java3D project. Everything was working fine and then when trying to run it yesterday I get this exception/error not long after starting it up:</p>
<pre><code>java.lang.UnsupportedClassVersionError: javax/vecmath/Point2f (Unsupported major.minor version 49.0)
</code></pre>
<p>Which I believe means that I'm trying to load a java 1.5 class file into a 1.4 jvm which is unsupported. However when I went to the class file to check this I saw this in the eclipse class file viewer:</p>
<pre><code>Compiled from Point2f.java (version 1.2 : 46.0, super bit)
</code></pre>
<p>So the class loader says it is version 49.0 but the class file says its 46.0. I've tried cleaning and fully rebuilding the project, I've confirmed that the compiler version for the project is 1.4, the JRE is 1.4 and for the run configuration the 1.4 jvm is selected. I'm totally stuck on this, does anyone have any idea what might be causing this?</p>
<p>Thanks</p>
<p>===EDIT===</p>
<p>It turns out that a version of java3d which was incompatible with java 1.4.2 had been installed in C:\Program Files\java\j2re1.4.2_18\lib\ext. I installed a newer version of Java3D to play around with in java6 and i guess it installed the libs in all my JREs even the ones which were incompatible.</p>

<p>I'm not talking about algorithmic stuff (eg use quicksort instead of bubblesort), and I'm not talking about simple things like loop unrolling.</p>
<p>I'm talking about the <em>hardcore</em> stuff.

<p>I could write myself a helper class that does this when given a functor, but I was wondering if there's a better approach, or if there's something already in the standard library (seems like there should be).</p>
<p>Answers I've found on StackOverflow are all for C# which doesn't help me.</p>
<p>Thanks</p>

<p>What I want to do is an outer join to a table, where I exclude records from the joined table based on matching a constant, however keep records from the main table. For example:</p>
<pre><code>SELECT a.id, a.other, b.baz
FROM a
LEFT OUTER JOIN b
ON a.id = b.id
AND b.bar = 'foo'
</code></pre>
<p>Expected results:</p>
<pre>
id other baz
-- ---------- -------
1 Has foo Include
2 Has none (null)
3 Has foobar (null)
</pre>
<p>I can't get the same results by putting it in the filter condition. If I use the following:</p>
<pre><code>SELECT a.id, a.other, b.baz
FROM a
LEFT OUTER JOIN b
ON a.id = b.id
WHERE (b.bar IS NULL OR b.bar = 'foo')
</code></pre>
<p>I get these incorrect results:</p>
<pre>
id other baz
-- -------- -------
1 Has foo Include
2 Has none (null)
</pre>
<p>Where it excluded records of A that happen to match a record of B where bar = 'foobar'. I don't want that, I want A to be present, but B to be nulls in that case.</p>
<p>Table B will have multiple records that need excluding, so I don't think I can filter this on the Crystal side without doing a lot of messing around to avoid problems from duplicate records from table A.</p>
<p>I cannot use a SQL command object, as the third party application that we are running the reports from seems to choke on SQL command objects.</p>
<p>I cannot use views, as our support contract does not permit database modifications, and our vendor considers adding views a database modification.</p>
<p>I am working with Crystal Reports XI, specifically version 11.0.0.895. In case it makes a difference, I am running against a Progress 9.1E04 database using the SQL-92 ODBC driver.</p>
<p>The sample tables and data used in the examples can be created with the following:</p>
<pre><code>CREATE TABLE a (id INTEGER, other VARCHAR(32));
CREATE TABLE b (id INTEGER, bar VARCHAR(32), baz VARCHAR(32));
insert into A (id, other) values ('1', 'Has foo');
insert into A (id, other) values ('2', 'Has none');
insert into A (id, other) values ('3', 'Has foobar');
insert into B (id, bar, baz) values ('1', 'foo', 'Include');
insert into B (id, bar, baz) values ('1', 'foobar', 'Exclude');
insert into B (id, bar, baz) values ('1', 'another', 'Exclude');
insert into B (id, bar, baz) values ('1', 'More', 'Exclude');
insert into B (id, bar, baz) values ('3', 'foobar', 'Exclude');
</code></pre>

<p>As soon as I change its position property it tries to animate to the new position and flickers all over the place:</p>
<pre><code> layer.position = CGPointMake(x, y)

<p>How can I move <code>CALayers</code> instantly? I can't seem to get my head around the Core Animation API.</p>

<p>I am having trouble understanding how the System Registry can help me convert a DateTime object into the a corresponding TimeZone. I have an example that I've been trying to reverse engineer but I just can't follow the one critical step in which the UTCtime is offset depending on Daylight Savings Time.</p>
<p>I am using .NET 3.5 (thank god) but It's still baffling me.</p>
<p>Thanks</p>
<p>EDIT: Additional Information: This question was for use in a WPF application environment. The code snippet I left below took the answer example a step further to get exactly what I was looking for. </p>

<p>I have SQL query, which is working nice on Oracle and MSSQL. Now I'm trying this on PostgreSQL and it gives a strange exception: <code>org.postgresql.util.PSQLException: ERROR: missing FROM-clause entry for table "main"</code></p>
<p>Here is the query: </p>
<pre><code>SELECT *
FROM "main" main
INNER JOIN "something_link" something_link ON main."id" = something_link."mainid"
INNER JOIN "something" somehting ON something_link."somethingid" = something."id"
INNER JOIN "type" type ON something."typeid" = type."id"
</code></pre>
<p>This is quite simple query and I can't see why it is not working on Windows XP SP2, PostgreSQL 8.3?</p>

<p>We have an intranet asp.net web application which uses the OOTB ASP.net membership and role providers. </p>
<p>Now we are planning to expose the application to internet, by moving the web server to the DMZ as represented in the following (crappy) text diagram</p>
<pre>
External Internal
internet --- Firewall --- Web server --- Firewall --- App Server --- Database
DMZ Intranet
</pre>
<p>Now the problem is that the asp.net membership and role providers on the web server cant connect to the sql server because of the internal firewall.</p>
<p>Have you ever faced such a scenario before? Will you recommend opening up ports in the internal firewall so that the webserver can directly connect to the SQL server? What other alternatives do I have (otherthan wring a custom provider myself)?</p>

<p>Anyone know how to get the position of a node using XPath?</p>
<p>Say I have the following xml:</p>
<pre><code><a>
<b>zyx</b>
<b>wvu</b>
<b>tsr</b>
<b>qpo</b>
</a>
</code></pre>
<p>I can use the following xpath query to select the third <b> node (<b>tsr</b>):</p>
<pre><code>a/b[.='tsr']
</code></pre>
<p>Which is all well and good but I want to <strong>return</strong> the ordinal position of that node, something like:</p>
<pre><code>a/b[.='tsr']/position()
</code></pre>
<p>(but a bit more working!)</p>
<p>Is it even possible?</p>
<p><strong>edit</strong>: Forgot to mention am using .net 2 so it's xpath 1.0!</p>
<hr />
<p><strong>Update</strong>: Ended up using <a href="https://stackoverflow.com/users/207/james-sulak">James Sulak</a>'s <a href="https://stackoverflow.com/questions/226405/find-position-of-a-node-using-xpath#227080">excellent answer</a>. For those that are interested here's my implementation in C#:</p>
<pre><code>int position = doc.SelectNodes("a/b[.='tsr']/preceding-sibling::b").Count + 1;
// Check the node actually exists
if (position > 1 || doc.SelectSingleNode("a/b[.='tsr']") != null)
{
Console.WriteLine("Found at position = {0}", position);
}
</code></pre>

<p>Is there a way in C# or .NET in general to create an attribute on a method which triggers an event when the method is invoked? Ideally, I would be able to run custom actions before and after the invocation of the method.</p>
<p>I mean something like this:</p>
<pre><code>[TriggersMyCustomAction()]
public void DoSomeStuff()
{
}
</code></pre>
<p>I am totally clueless how to do it or if it possible at all, but <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.conditionalattribute.aspx" rel="noreferrer">System.Diagnostic.ConditionalAttribute</a> might do a similar thing in the background. I am not sure though.</p>
<p><strong>EDIT</strong>: I forgot to mention that due to the circumstances of my specific case, performance is not really an issue.</p>

<p>When I first load data into a Silverlight DataGrid control, how can I make the screen look exactly as if the user had just clicked the header of the first column? In other words, the data should be sorted in ascending order according to that column's values, AND the little sort arrow should be displayed in the first column's header.</p>
<p>Assuming that's possible, can I also make it look as if the user had clicked the first column and then shift-clicked the second? In other words, can I programatically apply a two-part sort and have the screen look as if the user had done it?</p>

<p>I have a custom control that exposes a property. When I set it using a fixed value, everything works correctly. But if I try to set its value using the <%= %> tags, it goes a little whacky:</p>
<pre><code><cc:CustomControl ID="CustomControl" runat="server" Property1='<%= MyProperty %>' />
<%= MyProperty %>
</code></pre>
<p>When this gets rendered, the <%= MyProperty %> tag underneat the custom control is rendered as I expect (with the value of MyProperty). However, when I step into the Render function of the CustomControl, the value for Property1 is literally the string "<%= MyProperty %>" instead of the actual underlying value of MyProperty.</p>

<p>I've been reading up on this subject for a while. Suddenly the day has come where this solution is a necessity, not just a dream.</p>
<p>Through my reading, I've seen the popular differences being (file based, memcached, shared memory (mm), sql table, and custom).</p>
<p>The original idea we thought of was using a ZFS or AFS mounted on each of the application servers (LAMP boxes), and pointing the <code>session.save_path</code> php.ini setting to a directory from that mounted path.</p>
<p>I'd like to hear of success stories.</p>

<p>Someone at work just asked for the reasoning behind having to wrap a wait inside a synchronized.</p>
<p>Honestly I can't see the reasoning. I understand what the javadocs say--that the thread needs to be the owner of the object's monitor, but why? What problems does it prevent? (And if it's actually necessary, why can't the wait method get the monitor itself?)</p>
<p>I'm looking for a fairly in-depth why or maybe a reference to an article. I couldn't find one in a quick google.</p>
<p>Oh, also, how does thread.sleep compare?</p>
<p>edit: Great set of answers--I really wish I could select more than one because they all helped me understand what was going on.</p>

<p>I am trying to write a query for SQL Server 2005 but I can't figure out how to do it. I have a table with the following fields:</p>
<p><strong>MessageID int<br/>
CategoryID int<br/>
Priority tinyint<br/>
MessageText NVARCHAR(MAX)<br/></strong></p>
<p>I need a query that will return * for each row that has the highest priority within a Category. For example, if I had the following data:</p>
<p><strong>MessageID, CategoryID, Priority, MessageText</strong><br/>
1, 100, 1, Error #1234 occurred<br/>
2, 100, 2, Error #243 occurred<br/>
3, 100, 3, Error #976 occurred<br/>
4, 200, 4, Error #194 occurred<br/>
5, 200, 1, Error #736 occurred<br/>
6, 300, 3, Error #54 occurred<br/>
7, 300, 2, Error #888 occurred<br/></p>
<p>then the result would be:</p>
<p><strong>MessageID, CategoryID, Priority, MessageText</strong><br/>
3, 100, 3, Error #976 occurred<br/>
4, 200, 4, Error #194 occurred<br/>
6, 300, 3, Error #54 occurred<br/></p>
<p>Notice that it returns one row per category, and that it is the row which had the highest priority for that Category.</p>
<p>Can anyone tell me how I can write this query?</p>

<p>How do you solve the problem with soft hyphens on your web pages? In a text there can be long words which you might want to line break with a hyphen. But you do not want the hyphen to show if the whole word is on the same line.</p>
<p>According to comments on <a href="http://www.thefutureoftheweb.com/blog/breaking-long-urls" rel="noreferrer">this page</a> <code><wbr></code> is a non standard "tag soup invented by Netscape". It seems like <code>&shy;</code> <a href="http://www.cs.tut.fi/~jkorpela/shy.html" rel="noreferrer">has its problems with standard compliance as well</a>. There seems to be <a href="http://www.quirksmode.org/oddsandends/wbr.html" rel="noreferrer">no way to get a working solution for all browsers</a>.</p>
<p>Which is your way for handling soft hyphens and why did you choose it? Is there a preferred solution or best practice?</p>
<p><hr>
See related SO Discussion <a href="https://stackoverflow.com/questions/904/in-html-how-to-word-break-on-a-dash">here</a>.</p>

<p>Here's a silly fun question:</p>
<p>Let's say we have to perform a simple operation where we need half of the value of a variable. There are <em>typically</em> two ways of doing this:</p>
<pre><code>y = x / 2.0;
// or...
y = x * 0.5;
</code></pre>
<p>Assuming we're using the standard operators provided with the language, which one has better performance?</p>
<p>I'm guessing multiplication is typically better so I try to stick to that when I code, but I would like to confirm this. </p>
<p>Although personally I'm interested in the answer for <strong>Python</strong> 2.4-2.5, feel free to also post an answer for other languages! And if you'd like, feel free to post other fancier ways (like using bitwise shift operators) as well.</p>

<p>I'm betting that someone has already solved this and maybe I'm using the wrong search terms for google to tell me the answer, but here is my situation.</p>
<p>I have a script that I want to run, but I want it to run only when scheduled and only one at a time. (can't run the script simultaneously) </p>
<p>Now the sticky part is that say I have a table called "myhappyschedule" which has the data I need and the scheduled time. This table can have multiple scheduled times even at the same time, each one would run this script. So essentially I need a queue of each time the script fires and they all need to wait for each one before it to finish. (sometimes this can take just a minute for the script to execute sometimes its many many minutes)</p>
<p>What I'm thinking about doing is making a script that checks myhappyschedule every 5 min and gathers up those that are scheduled, puts them into a queue where another script can execute each 'job' or occurrence in the queue in order. Which all of this sounds messy. </p>
<p>To make this longer - I should say that I'm allowing users to schedule things in myhappyschedule and not edit crontab. </p>
<p>What can be done about this? File locks and scripts calling scripts?</p>

<p>I have the following regex that does a great job matching urls: </p>
<pre><code>((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)`
</code></pre>
<p>However, it does not handle urls without a prefix, ie. <strong>stackoverflow.com</strong> or <strong>www.google.com</strong> do not match. Anyone know how I can modify this regex to not care if there is a prefix or not?</p>
<hr>
<p>EDIT: Does my question too vague? Does it need more details?</p>
<hr>
<pre><code>(((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\)))?[\w\d:#@%/;$()~_?\+-=\\\.&]*)
</code></pre>
<p>I added a ()? around the protocols like <strong>Vinko Vrsalovic</strong> suggested, but now the regex will match nearly any string, as long as it has valid URL characters.</p>
<p>My implementation of this is I have a database that I manage the contents, and it has a field that either has plain text, a phone number, a URL or an email address. I was looking for an easy way to validate the input so I can have it properly formatted, ie. creating anchor tags for the url/email, and formatting the phone number how I have the other numbers formatted throughout the site. Any suggestions?</p>

<p>Say I have a form like:</p>
<pre><code>class GeneralForm(forms.Form):
field1 = forms.IntegerField(required=False)
field2 = forms. IntegerField(required=False)
</code></pre>
<p>And I want to show it twice on a page within one form tag each time with a different prefix e.g.,:</p>
<pre><code>rest of page ...
<form ..>
GeneralForm(data,prefix="form1").as_table()
GeneralForm(data,prefix="form2").as_table()
<input type="submit" />
</form>
rest of page ...
</code></pre>
<p>When the user submits this, how do I get the submitted form back into two separate forms to do validation, and redisplay it?</p>
<p><a href="http://docs.djangoproject.com/en/dev/ref/forms/api/#prefixes-for-forms" rel="noreferrer">This was the only documentation</a> I could find and it's peckish.</p>

<p>I seem to remember reading that it's possible to declare taglib directives such as:</p>
<pre><code><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
</code></pre>
<p>in web.xml. This eliminates the need to duplicate this directive in every JSP file where the taglib is used. Could someone tell me <em>how</em> these directives can be added to web.xml?</p>

<p>In Django templates, is there a variable in the context (e.g. <code>{{ BASE\_URL }}</code>, <code>{{ ROOT\_URL }}</code>, or <code>{{ MEDIA\_URL }}</code> that one can use to link to the <code>home</code> url of a project?</p>
<p>I.e. if Django is running in the root of a project, the variable (let's call it R) <code>{{ R }}</code> in a template would be <code>/</code>. If the root url is a sub-folder <code>http://host/X/</code> the variable <code>{{ R }}</code> would be <code>/X/</code> (or <code>http://host/X/</code>).</p>
<p>It seems painfully simple, but I can't find an answer. :) Thank you!</p>

<p>I am trying to make a view slide from top to bottom. This is not a big deal, I used <code>CABasicAnimation</code> for this. The problem is when I want to remove the view. I use this animation.</p>
<pre><code>CABasicAnimation *animation;
animation = [CABasicAnimation animationWithKeyPath:@"position"];
[animation setDelegate:self];
animation.toValue = [NSValue valueWithCGPoint:CGPointMake(self.view.layer.position.x, 0 - self.view.bounds.size.height / 2)];
animation.fromValue = [NSValue valueWithCGPoint:self.view.layer.position];
animation.autoreverses = NO;
animation.repeatCount = 0;
animation.duration = 0.25;
animation.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut];
[self.view.layer addAnimation:animation forKey:@"moveX"];
</code></pre>
<p>Which animates the view perfectly. But, after the animation finishes, my view appears again. So I added this line :</p>
<pre><code>[self.view removeFromSuperview];
</code></pre>
<p>Which removes the view, but with no animation. So I decided to add the remove code to this delegate:</p>
<pre><code>-(void) animationDidStop:(CAAnimation *) animation finished:(bool) flag
</code></pre>
<p>So now, the animation works, the view disappears, but sometimes, I can see the view appear and disappear faster, is like after the animation, the view appears, then the <code>animationDidStop</code> delegate is called, and the view disappears, obviously this is awful. What am I doing wrong?</p>

<p>I am not very good with Regex but I am learning.</p>
<p>I would like to remove some html tag by the class name. This is what I have so far :</p>
<pre><code><div class="footer".*?>(.*?)</div>
</code></pre>
<p>The first .*? is because it might contain other attribute and the second is it might contain other html stuff.</p>
<p>What am I doing wrong? I have try a lot of set without success.</p>
<h3>Update</h3>
<p>Inside the DIV it can contain multiple line and I am playing with Perl regex.</p>

<p>I've been spoiled by Visual studio 2008 and Eclipse and have to do a little maintainence work on a VB6 app.</p>
<p>Does anyone know of an alternative/ updated IDE for VB6?</p>
<p>A rewrite is not an option I'm just fixing a couple of bugs and it's a big codebase.</p>

<p>What's the best way to initialize an array in PowerShell?</p>
<p>For example, the code</p>
<pre><code>$array = @()
for($i=0; $i -lt 5;$i++)
{
$array[$i] = $FALSE
}
</code></pre>
<p>generates the error</p>
<pre><code>Array assignment failed because index '0' was out of range.
At H:\Software\PowerShell\TestArray.ps1:4 char:10
+ $array[$ <<<< i] = $FALSE

<p>So I have xml that looks like this:
</p>
<pre class="lang-html prettyprint-override"><code><todo-list>
<id type="integer">#{id}</id>
<name>#{name}</name>
<description>#{description}</description>
<project-id type="integer">#{project_id}</project-id>
<milestone-id type="integer">#{milestone_id}</milestone-id>
<position type="integer">#{position}</position>
<!-- if user can see private lists -->
<private type="boolean">#{private}</private>
<!-- if the account supports time tracking -->
<tracked type="boolean">#{tracked}</tracked>
<!-- if todo-items are included in the response -->
<todo-items type="array">
<todo-item>
...
</todo-item>
<todo-item>
...
</todo-item>
...
</todo-items>
</todo-list>
</code></pre>
<p>How would I go about using .NET's serialization library to deserialize this into C# objects? </p>
<p>Currently I'm using reflection and I map between the xml and my objects using the naming conventions.</p>

<p>Website started life originally under IIS 6 and the site worked great there. Now after relocating to a new server running W2K8S, everything but mail delivery from the website now works great under IIS 7.</p>
<p>Researched briefly on the Web to see if anybody had a good resolution, but no avail... Not even a glimmer of hope on Microsoft's own support site.</p>
<p>Here are the steps taken so far on the new W2K8S box:</p>
<ul>
<li>Added the feature for SMTP under the Server Manager</li>
<li>Enabled SMTP e-mail for the site itself in IIS 7 Manager to deliver e-mail to SMTP server local host, unsuccessful</li>
<li>Enabled SMTP e-mail for the root site in IIS 7 Manager (not sure if that needs to be on to enable sites) to deliver e-mail to SMTP server local host, unsuccessful</li>
</ul>
<p>After failing those basic setups, I wanted to be sure I can actually talk from/to the serveron port 25. And I can successfully telnet from/to the server in question to a test e-mail on port 25 get a HELO, etc. So I do not believe it is a firewall config issue.</p>
<p>The IIS 7 setup test was performed with both anonymous and Windows authentication - no luck either way.</p>
<p>Manually checked Web Config file and it reflects correct entry for the server to use the localhost.</p>
<p>Read the manual and no luck there either... :-/</p>

<p>I have a web service in C# and would like to have a nested inner class, that abstracts away the session collection, something like this: </p>
<pre>
<code>
public class Service : System.Web.Services.WebService
{
[WebMethod]
public string Foo(string ticket)
{
SessionPool.getSession(ticket);
}
private class SessionPool
{
public static Session getSession(string ticket)
{
// this is what i want to do, but I can't access Context
return (Session)Context.Session[ticket];
}
}
}
</code>
</pre>
<p>Is it possible to access the HTTP context of the WebService class via a nested class? If not, is there way I can store the reference to it?</p>

<p>I've got a ant <code>build.xml</code> that uses the <code><copy></code> task to copy a variety of xml files. It uses filtering to merge in properties from a <code>build.properties</code> file. Each environment (dev, stage, prod) has a different <code>build.properties</code> that stores configuration for that environment.</p>
<p>Sometimes we add new properties to the Spring XML or other config files that requires updating the <code>build.properties</code> file.</p>
<p>I want ant to fail fast if there are properties missing from <code>build.properties</code>. That is, if any raw <code>@...@</code> tokens make it into the generated files, I want the build to die so that the user knows they need to add one or more properties to their local build.properties.</p>
<p>Is this possible with the built in tasks? I couldn't find anything in the docs. I'm about to write a custom ant task, but maybe I can spare myself the effort.</p>
<p>Thanks</p>

<p>I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an <code>id</code> attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome.</p>
<p>Edit:</p>
<ul>
<li><p><strong>If the GreaseMonkey script is out of scope, how are you referencing the elements later?</strong> They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached.</p></li>
<li><p><strong>Can't you just use a custom property on the element?</strong> Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work.</p></li>
<li><p><strong>Wait, can you or can you not modify the document?</strong> I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question.</p></li>
<li><p><strong>Can you not use closures?</strong> Closuses did turn out to work, although I initially thought they wouldn't. See my later post.</p></li>
</ul>
<p>It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."</p>

<p>I have a requirement to export the results of a SQL query to excel. I am currently exporting it into 2007 format, but everything I have found will only run in a x86 enviroment. The web site where the export is to take place is running on a x64 version of IIS.</p>
<p>Changing IIS to run x86 is not an option. My current solution is to save the export request to a DB, and write a windows service that can run in x86 and use that service to process the request.</p>
<p>I have started to look at the Open XML Format SDK 2.0 as a possible better solution. </p>
<p>Has anyone got any experence that would lend to a native .NET solution.</p>
<p>FYI: My budget is $0.00 so buying a tool is a no-go.</p>

<p>I was running some dynamic programming code (trying to brute-force disprove the Collatz conjecture =P) and I was using a dict to store the lengths of the chains I had already computed. Obviously, it ran out of memory at some point. Is there any easy way to use some variant of a <code>dict</code> which will page parts of itself out to disk when it runs out of room? Obviously it will be slower than an in-memory dict, and it will probably end up eating my hard drive space, but this could apply to other problems that are not so futile.</p>
<p>I realized that a disk-based dictionary is pretty much a database, so I manually implemented one using sqlite3, but I didn't do it in any smart way and had it look up every element in the DB one at a time... it was about 300x slower.</p>
<p>Is the smartest way to just create my own set of dicts, keeping only one in memory at a time, and paging them out in some efficient manner?</p>

<p>QA tester was reading HTML/JS code to write a functional test of a web form, and saw:</p>
<pre><code>if (form_field == empty)
{
...do stuff for empty field
}
else if (form_field != empty)
{
...do stuff for non-empty field
}
else
{
...do stuff that will never be done
}
</code></pre>
<p>After a couple embarrassing attempts, tester realized that they couldn't trigger the alert strings hidden in the third block.</p>
<p>Things I'm wondering are if this Is this problem more or less language specific (can non-JS people learn lessons here?) and are there legitimate reasons code ended up this way?</p>
<p>How can I find/address the problem?</p>

<p>When you are monitoring the TFS build from Visual Studio (2008 or 2005), you can see where it is up to.</p>
<p>The issue is that I have some Post-Build custom steps I would like the developer to be able to see directly throught the UI. Those steps take some times and we can also get a "timing" of the build step.</p>
<p>Any idea how to have it displayed?</p>

<p>I have a struts2 application with a single page that may show one of a number of values stored in a database. The application is for a school with many departments and each department has many programs. The department page is accessed using a url like this</p>
<pre><code>department.action?id=2
</code></pre>
<p>and the DepartmentAction will load the Department with id = 2 for display. All this is fine if the user is just browsing around the site but it gets uncomfortable if I want to provide a link to say the Engineering department in the newspapers. The link will have to be www.myschooldomain.com/department.action?id=2. I see a number of problems with this.</p>
<p>First, it is not user friendly. Second, it is prone to be broken because the departments are dynamically maintained and the id for a department could change without warning making the link unstable.</p>
<p>I would prefer to print a url like this: www.myschooldomain.com/department/engineering and have that somehow go to department.action?id=2.</p>
<p>My thoughts so far: create an action that will parse the url for the department name at the end then look it up by name. Maybe I could add a friendlyurl field to the database for each department.</p>
<p>But the question is: Is there a better way to do this in struts2?</p>
<p>Thanks.</p>
<p><strong>Update (May 2009):</strong> I just happened to stumble back over this question and thought that I would say what I did to solve it. </p>
<p>I created a new package in the struts.xml called departments. In this package there is only one action mapped to *. So it catches all requests to mydomain.com/departments/anything.html.</p>
<p>In the action class I simply parse the url and look for the part between departments/ and .html and that is the name of the department so I can do a lookup in the database for it. This has been working fine for almost 5 months now and I have implemented it for other areas of the site.</p>

<p>I have downloaded Privoxy few weeks ago and for the fun I was curious to know how a simple version of it can be done.</p>
<p>I understand that I need to configure the browser (client) to send request to the proxy. The proxy send the request to the web (let say it's a http proxy). The proxy will receive the answer... but how can the proxy send back the request to the browser (client)?</p>
<p>I have search on the web for C# and http proxy but haven't found something that let me understand how it works behind the scene correctly. (I believe I do not want a reverse proxy but I am not sure).</p>
<p>Does any of you have some explication or some information that will let me continue this small project?</p>
<h2>Update</h2>
<p>This is what I understand (see graphic below).</p>
<p><strong>Step 1</strong> I configure the client (browser) for all request to be send to 127.0.0.1 at the port the Proxy listen. This way, request will be not sent to the Internet directly but will be processed by the proxy.</p>
<p><strong>Step2</strong> The proxy see a new connection, read the HTTP header and see the request he must executes. He executes the request.</p>
<p><strong>Step3</strong> The proxy receive an answer from the request. Now he must send the answer from the web to the client but how???</p>

<p>We have a netbeans project that has an xsd that we use to create a wsdl and we use the wsdl to create a webservice. Since we are using types in our xsd jaxb is used and one of our webservice methods looks like this: </p>
<pre><code>public void someMethod( org.netbeans.xml.schema.line.Line x )...
</code></pre>
<p>So that leaves us a problem with subversion since the Line objects are generated by netbeans. So we want to do is either tell netbeans to place the files inside of the project? Or tell netbeans that we will generate the jaxb code and that they should use our classes when the webservice calls are processed? How can we accomplish one of these, what are some other alternatives?</p>

<p>After discussing with a newly arrived developer in my team, I realized that there are still, in C++, habits of using C constructs because they are supposed to be better (i.e. faster, leaner, prettier, pick your reason).</p>
<p><strong>What are the examples worth sharing, showing a C constructs, compared to the similar C++ construct?</strong></p>
<p>For each example, I need to read the reasons the C++ construct is as good as or even better the original C construct. The aim is to offer alternatives to some C constructs that are considered somewhat dangerous/unsafe in C++ code (C++0x valid only answers are accepted as long as clearly marked as C++0x only).</p>
<p>I'll post below an answer (struct inline initialization) as an example.</p>
<p><em>Note 1: Please, one answer per case. If you have multiple cases, please post multiple answers</em></p>
<p><em>Note 2: <s>This is not a C question. Do not add the "C" tag to this question.</s></em> <em>This is not supposed to become a fight between C++ and C. Only the study of some constructs of the C subset of C++, and their alternative in other C++ "toolkits"</em></p>
<p><em>Note 3: This is not a C-bashing question. I want reasons. Boasting, bashing, and unproven comparisons will be downmodded. Mentioning C++ features without a C equivalent could be considered out of topic: I want the put side by side a C feature against a C++ feature.</em></p>

<p>I'm working on a C++ prettyprinter and would like to show the results of the prettyprinter by comparing code before and after running it. Does anyone know where I can find some ugly C++ code to run through the prettypretty? Ideally the code would come from some open source software.</p>

<p>I want to create a simple bit of JS code that creates an image element in the background and doesn't display anything. The image element will call a tracking URL (such as Omniture) and needs to be simple and robust and work in IE 6 =< only. Here is the code I have:</p>
<pre><code>var oImg = document.createElement("img");
oImg.setAttribute('src', 'http://www.testtrackinglink.com');
oImg.setAttribute('alt', 'na');
oImg.setAttribute('height', '1px');
oImg.setAttribute('width', '1px');
document.body.appendChild(oImg);
</code></pre>
<p>Is this the simplest but most robust (error free) way to do it?</p>
<p>I cannot use a framework like jQuery. It needs to be in plain JavaScript.</p>

<p>I am currently trying to create an Exception handler built into my windows service that, on an unhandled exception, sends a message to another program. I have built the method and gotten the communication working, but it seems that every time my program throws the error, (I have a raise call in the code to force it.) windows catches it instead and the Handler isn't called. Can anyone explain what I am doing wrong?.</p>
<p>Simplified Code to explain:</p>
<pre><code>procedure unhandled();
begin
raise Exception.Create('Unhandled');
end;
procedure ExceptionHandler(ExceptObject: TObject; ExceptAddr: Pointer);
begin
WriteLn('Display: ' + Exception(ExceptObject).Message);
//send Message Here
end;
</code></pre>
<p>I call this code to run it:</p>
<pre><code>WriteLn('Starting');
ExceptProc := @ExceptionHandler;
unhandled();
</code></pre>
<p>I would expect the output to be:</p>
<blockquote>
<p>Starting<br/>
Display: Unhandled</p>
</blockquote>
<p>but all it does is display:</p>
<blockquote>
<p>Starting</p>
</blockquote>
<p>Then windows returns a command prompt after about 5 seconds.</p>
<p>Why isn't the handler being properly called?</p>
<p>P.S. I've been running these tests in a console app for testing.</p>
<p>EDIT:</p>
<p>Here's some more information:</p>
<p>Apparently when you have an assigned ExceptProc, your program shouldn't throw the normal runtime 217 error. I'm guessing this is what windows is catching, From what I can see however, my program is throwing that runtime error, and I can't get an ErrorProc to catch it either.</p>

<p>I find it curious that the most obvious way to create <code>Date</code> objects in Java has been deprecated and appears to have been "substituted" with a not so obvious to use lenient calendar.</p>
<p>How do you check that a date, given as a combination of day, month, and year, is a valid date?</p>
<p>For instance, 2008-02-31 (as in yyyy-mm-dd) would be an invalid date.</p>

<p>I came across a code snippet like this:</p>
<p><code>Timestamp expiryDate = Timestamp.valueOf(dateStr + " " + "23:59:59.000"); </code></p>
<p>Here dateStr is a string entered by the user in a form, in the format yyyy-mm-dd. Now the behavior of Timestamp.valueOf is such that it converts non-existent dates into appropriate proper dates. Say 31st June 2008 into 01st July 2008. </p>
<p>How can I check in Java if the dateStr string is in fact a valid date ? I know I can manually do the check, but what I would like to know is whether any method is already available to do the same.</p>

<p>I've been working with code synthesis xsd to generate an xml tree to ensure constinency of the xml output to the original xsd.</p>
<p>After initial testing, everything looked ok but when I tried entering invalid values (correct type, but outside the defined range), the values were allowed.</p>
<p>Although the xml is well formed and conforms to the types set in the xsd, it is not a valid xml wrt the schema.</p>
<p>Has anybody else used this tool and/or come up across this problem?</p>

<p>If I have hundreds/thousands of client computers WCP'ing to my server, should I respond with a '200 OK' type message stating that I received the data and stored it in the db successfully?</p>
<p>Is this already built-into WCF?</p>

<p>I can't seem to grok the concept of "loose coupling." I suppose it doesn't help that the word "loose" usually has a negative connotation, so I always forget that loose coupling is a <em>good</em> thing.</p>
<p>Will somebody please show some "before" and "after" code (or pseudocode) that illustrates this concept?</p>

<p>What is the best way to sync up two lists each of which may contain items not in the other? As shown the lists are not sorted - although if necessary sorting them first would not be an issue.</p>
<pre><code>List 1 = a,b,c,e
List 2 = b,e,c,d
</code></pre>
<p>Using the lists above, I'm looking for a solution that will write out to a spreadsheet in two columns:</p>
<pre><code>a
b b
c c
d
e e
</code></pre>

<p>I have a Google Map that suddenly stopped working for no apparent reason (I hadn't touched the code for months, but the wrapper code from our CMS may have changed without Corporate telling me).</p>
<p><a href="http://www.democratandchronicle.com/section/builder" rel="nofollow noreferrer">http://www.democratandchronicle.com/section/builder</a></p>
<p>(sorry about the nasty HTML outside the map, most of that comes from our corporate parent...)</p>
<p>I've narrowed it down to this part of my <code>drawMarker</code> function:</p>
<pre><code>GEvent.addListener(marker, 'click', function() {
marker.openInfoWindowHtml(html, { maxWidth: 500 });
});
</code></pre>
<p>Of note:</p>
<ul>
<li><code>alert(html);</code> displays the correct HTML for the infowindow.</li>
<li>The HTML in the html variable is indeed valid.</li>
<li>The click event is firing (confirmed by <code>alert('test');</code> within it)</li>
<li>Another map I host on the same site <a href="http://www.democratandchronicle.com/garagesales" rel="nofollow noreferrer">works fine</a>, despite similar code.</li>
<li>No JavaScript errors in Firebug or IE that I can see.</li>
</ul>
<p>I've been bashing my head against this for a while. What am I missing?</p>

<p>I have an <code>IList<T></code> that I need to sort, and I would rather not copy the list if possible. I've noticed that <code>ArrayList</code> has an <code>Adapter</code> static method that wraps the passed list without copying it, but this takes an <code>IList</code> and I have an <code>IList<T></code>. Is it safe to cast from a <code>System.Collections.Generic.IList<T></code> to a <code>System.Collections.IList</code> and just use the <code>Adapter</code> method?</p>
<p>Note that this is .Net 2.0, so LINQ is not an option.</p>

<p>I've used several apps now that launch the itunes store directly from the app. I'm even using some on my 2.1 iPod 2G.</p>
<p>I know there's a bug in 2.1 that prevents appstore links from working in safari, but somehow people are launching the appstore directly, not even through safari.</p>
<p>How do you do this? Is it an undocumented openURL feature?</p>

<p>If I have two UIColors, what's the best way to draw an even gradient between them over an arbitrarily-sized area?</p>
<p>I am guessing you would create a UIView subclass and use the CG drawing methods in the drawRect method. I just don't know which ones, or if there are any pitfalls to watch out for, like performance. Has anyone done this?</p>

<p>In Java, given a timestamp, how to reset the time part alone to 00:00:00 so that the timestamp represents the midnight of that particular day ?</p>
<p>In T-SQL, this query will do to achieve the same, but I don't know how to do this in Java.</p>
<p><code>SELECT CAST( FLOOR( CAST(GETDATE() AS FLOAT ) ) AS DATETIME) AS 'DateTimeAtMidnight';</code></p>

<p>I have two tables Institutions and Results and I want to see if there are any results for institutions that way I can exclude the ones that don't have results.</p>
<p>Can I get better performance using a JOIN or using EXISTS?</p>
<p>Thank you,<br>

<p>I am wondering what server control people generally use for surrounding and separating blocks of related controls and content in a Web Forms scenario. Often times I need to surround a block of HTML and related Server controls with a 'panel' that I can show or hide based upon some UI logic in the code behind. I am usually faced with either using a Panel, however this doesn't work if I need to surround multiple TR's in a table for example because the Panel renders as a div which is invalid inside a Table tag. In this situation I usually just set each TR to runat server and show/hide each of them individually, but there must be a better way. I have seen the PlaceHolder control used for this scenario, but wanted to know if anyone does this or has any other suggestions.</p>

<p>I typically use extension methods very sparingly. When I do feel compelled to write an extension method, I sometimes want to overload the method. My question is, what are your thoughts on extension methods calling other extension methods? Bad practice? It feels wrong, but I can't really define why.</p>
<p>For example, the second CaselessIs method calls the first:</p>
<pre><code>public static bool CaselessIs(this string s, string compareTo)
{
return string.Compare(s, compareTo, true) == 0;
}
public static bool CaselessIs(this string s, IEnumerable<string> compareTo)
{
foreach(string comparison in compareTo)
{
if (s.CaselessIs(comparison))
{
return true;
}
}
return false;
}
</code></pre>
<p>Would it be more appropriate to not do this? The downside would be that it violates DRY.</p>
<pre><code>public static bool CaselessIs(this string s, string compareTo)
{
return string.Compare(s, compareTo, true) == 0;
}
public static bool CaselessIs(this string s, IEnumerable<string> compareTo)
{
foreach(string comparison in compareTo)
{
if (string.Compare(s, comparison, true) == 0)
{
return true;
}
}
return false;
}
</code></pre>

<p>I'd love to create a "back" left-arrow-bezel button in a <code>UIToolbar</code>.</p>
<p>As far as I can tell, the only way to get one of these is to leave <code>UINavigationController</code> at default settings and it uses one for the left bar item. But there's no way I can find to create one as a <code>UIBarButtonItem</code>, so I can't make one in a standard <code>UIToolbar</code>, even though they're very similar to <code>UINavigationBar</code>s.</p>
<p>I could manually create it with button images, but I can't find the source images anywhere. They have alpha-channel edges, so screenshotting and cutting won't get very versatile results.</p>
<p>Any ideas beyond screenshotting for every size and color scheme I intend to use?</p>
<p><strong>Update:</strong> PLEASE STOP dodging the question and suggesting that I shouldn't be asking this and should be using <code>UINavigationBar</code>. My app is Instapaper Pro. It shows only a bottom toolbar (to save space and maximize readable content area), and I wish to put a left-arrow-shaped Back button in the bottom.</p>
<p>Telling me that I shouldn't need to do this <strong>is not an answer</strong> and certainly doesn't deserve a bounty.</p>

<p>I have ListView with Grouping Items. Grouping uses custom GroupStyle (Expander). I would like to have check box which will Expand and collapse all groups when. It works fine untill I click manually on the group header and expand or collapse that group. After clicking that particular group stops to respond on check box selection. Looks like binding is broken after user manually clicks on the group.</p>
<p>Please advise what I am doing wrong.</p>
<p>Thanks a lot.</p>
<p>Sincerely,
Vlad.</p>

<p>I'm wonder what the best way to convert a byte array (length 4) to an integer is in vb.net? I'm aware of BitConverter, but it seems like quite a waste to do a function call to do something that should be able to be done by copying 4 bytes of memory. Along the same lines, what about converting a single/double from it's binary representation to an single/double variable.</p>

<p>I have somewhat of a staging server on the public internet running copies of the production code for a few websites. I'd really not like it if the staging sites get indexed. </p>
<p>Is there a way I can modify my httpd.conf on the staging server to block search engine crawlers? </p>
<p>Changing the robots.txt wouldn't really work since I use scripts to copy the same code base to both servers. Also, I would rather not change the virtual host conf files either as there is a bunch of sites and I don't want to have to remember to copy over a certain setting if I make a new site.</p>

<p>I am trying to dynamically load the contents of a div tag with a .cfm page that contains a cfchart in png format. When the user clicks on a link, I am using the load function to put the .cfm page into the div.</p>
<pre><code>$("#bank").bind("click", function(){
$("#chartx").load("bank.cfm");
});
</code></pre>
<p>I can get this to come up perfectly in Firefox, but not in IE6. It gives no error messages.</p>

<p>Is it possible to use the asp templating engine (With the partial code-behind class, dynamic <% ... %> blocks and such) to generate non HTML? I want to have a clean and maintainable way to generate code dynamically. (Specifically, I want to generate LaTeX code populated with values from a database.) </p>
<p>Currently my LaTeX templates are resource strings with placeholders that I string.replace with the database values. This solution rapidly became very difficult to maintain and clean. I'd really like to use the dynamic blocks from aspx markup, but I'm not sure a) whether aspx will throw a fit when the output isn't HTML, or b) how to actually render the result into a .tex file.</p>
<p>The generating code itself is located in a C# .dll. We're using .NET 3.5</p>
<p>Is this possible? Thanks in advance. </p>

<p>I have need to write an application which uses a speech recognition engine -- either the built in vista one, or a third party one -- that can display a word or phrase, and recognise when the user reads it (or an approximation of it). I also need to be able to switch quickly between languages, without changing the language of the operating system.</p>
<p>The users will be using the system for very short periods. The application needs to work without the requirement of first training the recognition engine to the users' voices.</p>
<p>It would also be fantastic if this could work on Windows XP or lesser versions of Windows Vista.</p>
<p>Optionally, the system needs to be able to read information on the screen back to the user, in the user's selected language. I can work around this specification using pre-recorded voice-overs, but the preferred method would be to use a text-to-speech engine.</p>
<p>Can anyone recommend something for me?</p>

<p>I am a support engineer and our company's product allows XSLT transforms to customize outputs.</p>
<p>I made a xsl transform for this purpose. It works well for source files of typical size (several 100k), but occasionally a really huge (10M) source file will come by. In such case, the output is not generated even if I let it grind several days.</p>
<p>The SW engineering team tested it and discovered that for the transform and large source file in question is indeed very slow (>days), if our product is compiled to use the transform engine in .Net 1.1, but if they compile it with .Net 2.0, it is plenty fast (about 1-2 minutes).</p>
<p>The long term solution obviously is, wait for the next release.</p>
<p>For the short term I am wondering the following:
1) Is XSLT flexible enough that there are more efficient and less efficient ways to acheive the same result? For example, is it possible that the way I structured the xsl, the transform engine has to iterate from the beginning of the source file many many times, taking longer and longer as the next result piece gets farther and farther from the beginning? (Schlemiel the Painter), or
2) Is it more dependent on how the transform engine interprets the xsl?</p>
<p>If 2 is the case, I don't want to waste a lot of time trying to improve the xsl (I am not a big xsl genius, it was hard enough for me to achieve what little I did...).</p>
<p>Thanks!</p>

<p>I have a console application that require to use some code that need administrator level. I have read that I need to add a Manifest file myprogram.exe.manifest that look like that :</p>
<pre><code><?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel level="requireAdministrator">
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
</code></pre>
<p>But it still doesn't raise the UAC (in the console or in debugging in VS). How can I solve this issue?</p>
<h2>Update</h2>
<p>I am able to make it work if I run the solution in Administrator or when I run the /bin/*.exe in Administrator. I am still wondering if it's possible to have something that will pop when the application start instead of explicitly right click>Run as Administrator?</p>

<p>I am working on interactive SVG/AJAX interfaces where elements are created and repositioned on-the-fly by users. I'd like to support the ability for users to export their current view to a PNG image and/or an SVG document. I'd really like the SVG document to be as simple as possible (without a lot of nested transforms). Is there any framework that already supports this?</p>
<p>I'm currently asking my users to use the Ctrl+Alt+PrntScrn technique, and I don't want to ask them to install any software/plugins. </p>
<p>The server-side code is implemented in PHP right now, if that helps. I've already implemented the ability to generate a PNG image from the "original" document (before the client makes any modifications) using ImageMagick.</p>

<p>I've spent most of the day making what are basically some housekeeping changes to the codebase of one of our projects (replacing all <code>System.out.println()</code> calls with log4j).</p>
<p>I'm kind of curious how many lines of code I've updated with this set of changes.</p>
<p>Is there anyway with <code>cvs diff</code> or another command to get an accurate count of how many lines have changed?</p>
<p>I've tried</p>
<pre><code>cvs diff -b -B -R
</code></pre>
<p>to get all of the changes in the working directory (and recursively the subdirectories), but for each file changed it also prints out file/version information, which makes just counting the lines of output useless.</p>
<p>Any ideas?</p>

<p>I need to convert a Word document into HTML file(s) in Java. The function will take input an word document and the output will be html file(s) based on the number of pages the word document has i.e. if the word document has 3 pages then there will be 3 html files generated having the required page break.</p>
<p>I searched for open source/non-commercial APIs which can convert doc to html but for no result. Anybody who have done this type of job before please help.</p>
<p>Thanks</p>

<p>As a followup to my <a href="https://stackoverflow.com/questions/227143/java-what-is-javaawtcomponentgetname-and-setname-used-for">question about the java.awt.Component.getName() property</a>, I'm wondering if there is a way of squirreling an arbitrary object somewhere in a Component, similar to the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.control.tag.aspx" rel="nofollow noreferrer">tag property in .NET</a>? This would be really handy for any code that does work to a component but doesn't necessarily know what that component is.</p>
<p>For example, say I'm trying to implement an application-wide help system that knows to look at any component currently pointed to by the mouse, reach into that component and pull out it's help text and display it in it's own pane on the screen (no, I don't want to use a tooltip). My answer currently is to use the Name (getName()/setName()) to store the help text, and this will work, but the Name has to be a string. If I wanted to get fancier and store anything other than a string, I think I'd be stuck.</p>

<p>I am interested in making a Google Talk client using Python and would like to use the Twisted libraries Words module. I have looked at the examples, but they don't work with the current implementation of Google Talk.</p>
<p>Has anybody had any luck with this? Would you mind documenting a brief tutorial?</p>
<p>As a simple task, I'd like to create a client/bot that tracks the Online time of my various Google Talk accounts so that I can get an aggregate number. I figure I could friend the bot in each account and then use the XMPP presence information to keep track of the times that I can then aggregate.</p>
<p>Thanks.</p>

<p>I know how to find a method in java using a fixed string,</p>
<pre><code>someClass.getMethod("foobar", argTypes);
</code></pre>
<p>but is there a way to use a regular expression rather than a fixed string to find a method on a given class? </p>
<p>An example of the usage might be if I wanted to find a method that was called either "foobar" or "fooBar". Using a regular expression like "foo[Bb]ar" would match either of these method names.</p>

<p>My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers.</p>
<p>I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches.</p>
