<p>Jquery has a great language construct that looks like this:</p>
<pre><code>$(document).ready(function() {
$("a").click(function() {
alert("Hello world!");
});
});
</code></pre>
<p>As you might guess this, once the document has loaded, binds a custom function to the onClick event of all <strong><em>a</em></strong> tags.</p>
<p>The question is, how can I achieve this same kind of behavior in Prototype?</p>

<p>I'm trying to find a source control for my own personal use that's as simple as possible. The main feature I need is being able to read/pull a past version of my code. I am the only developer. I've looked at a lot of different version control systems, but they all seem way more complicated than I need. I need one that's simple, runs under Windows, and doesn't expose itself to the network.</p>
<p>Specifically, the version control system should <em>not</em> require exposing an HTTP interface, it should interact with the local filesystem only. It just needs to be a version control system geared for one guy and one guy only. Graphical UI is a plus.</p>
<p>Does anyone know of software would satisfy what I'm looking for?</p>
<p>Thanks!</p>
<p>-Mike</p>

<p>In Oracle, the number of rows returned in an arbitrary query can be limited by filtering on the "virtual" <code>rownum</code> column. Consider the following example, which will return, at most, 10 rows.</p>
<pre>SELECT * FROM all_tables WHERE rownum <= 10</pre>
<p>Is there a simple, generic way to do something similar in Ingres?</p>

<p>I'm using JavaScript to hide an image and show some text thats hidden under it. But, when the text is shown if you scroll over it, it fires the mouseout event on the container, that then hides the text and shows the image again, and it just goes into a weird loop.</p>
<p>The html looks like this:</p>
<pre><code><div onmouseover="jsHoverIn('1')"
onmouseout="jsHoverOut('1')">
<div id="image1" />
<div id="text1" style="display: none;">
<p>some content</p>
<p>some more content</p>
</div>
</div>
</code></pre>
<p>And the javascript (It uses scriptaculous):</p>
<pre><code>function jsHoverIn(id) {
if(!visible[id]) {
new Effect.Fade ("image" + id, {queue: { position: 'end', scope: id } });
new Effect.Appear ("text" + id, {queue: { position: 'end', scope: id } });
visible[id] = true;
}
}
function jsHoverOut (id) {
var scope = Effect.Queues.get(id);
scope.each(function(effect) { effect.cancel(); });
new Effect.Fade ("text" + id, {queue: { position: 'end', scope: id } });
new Effect.Appear ("image" + id, {queue: { position: 'end', scope: id } });
visible[id] = false;
}
</code></pre>
<p>This seems really simple, but i just cant wrap my head around it.</p>

<p>My company is looking to start distributing some software we developed and would like to be able to let people try the software out before buying. We'd also like to make sure it can't be copied and distributed to our customers' customers.</p>
<p>One model we've seen is tying a license to a MAC address so the software will only work on one machine.</p>
<p>What I'm wondering is, what's a good way to generate a license key with different information embedded in it such as license expiration date, MAC address, and different software restrictions?</p>

<p>I need to find out time taken by a function in my application. Application is a MS VIsual Studio 2005 solution, all C code. </p>
<p>I used thw windows API GetLocalTime(SYSTEMTIME *) to get the current system time before and after the function call which I want to measure time of.
But this has shortcoming that it lowest resolution is only 1msec. Nothing below that. So I cannot get any time granularity in micro seconds. </p>
<p>I know that time() which gives the time elapsed since the epoch time, also has resolution of 1msec (No microseconds) </p>
<p>1.) Is there any other Windows API which gives time in microseconds which I can use to measure the time consumed by my function?</p>

<p>Is it possible to extract all of the VBA code from a Word 2007 "docm" document using the API?</p>
<p>I have found how to insert VBA code at runtime, and how to delete all VBA code, but not pull the actual code out into a stream or string that I can store (and insert into other documents in the future).</p>
<p>Any tips or resources would be appreciated.</p>
<p><strong>Edit</strong>: thanks to everyone, <a href="https://stackoverflow.com/users/3655/aardvark">Aardvark</a>'s answer was exactly what I was looking for. I have converted his code to C#, and was able to call it from a class library using Visual Studio 2008.</p>
<pre><code>using Microsoft.Office.Interop.Word;
using Microsoft.Vbe.Interop;
...
public List<string> GetMacrosFromDoc()
{
Document doc = GetWordDoc(@"C:\Temp\test.docm");
List<string> macros = new List<string>();
VBProject prj;
CodeModule code;
string composedFile;
prj = doc.VBProject;
foreach (VBComponent comp in prj.VBComponents)
{
code = comp.CodeModule;
// Put the name of the code module at the top
composedFile = comp.Name + Environment.NewLine;
// Loop through the (1-indexed) lines
for (int i = 0; i < code.CountOfLines; i++)
{
composedFile += code.get_Lines(i + 1, 1) + Environment.NewLine;
}
// Add the macro to the list
macros.Add(composedFile);
}
CloseDoc(doc);
return macros;

<p>Recently I was talking to a co-worker about C++ and lamented that there was no way to take a string with the name of a class field and extract the field with that name; in other words, it lacks reflection. He gave me a baffled look and asked when anyone would ever need to do such a thing.</p>
<p>Off the top of my head I didn't have a good answer for him, other than "hey, I need to do it right now". So I sat down and came up with a list of some of the things I've actually done with reflection in various languages. Unfortunately, most of my examples come from my web programming in Python, and I was hoping that the people here would have more examples. Here's the list I came up with:</p>
<ol>
<li><p>Given a config file with lines like<br>
x = "Hello World!"<br>
y = 5.0<br>
dynamically set the fields of some <code>config</code> object equal to the values in that file. (This was what I wished I could do in C++, but actually couldn't do.)</p></li>
<li><p>When sorting a list of objects, sort based on an arbitrary attribute given that attribute's name from a config file or web request.</p></li>
<li><p>When writing software that uses a network protocol, reflection lets you call methods based on string values from that protocol. For example, I wrote an IRC bot that would translate<br>
<code>!some_command arg1 arg2</code><br>
into a method call <code>actions.some_command(arg1, arg2)</code> and print whatever that function returned back to the IRC channel.</p></li>
<li><p>When using Python's __getattr__ function (which is sort of like method_missing in Ruby/Smalltalk) I was working with a class with a whole lot of statistics, such as late_total. For every statistic, I wanted to be able to add _percent to get that statistic as a percentage of the total things I was counting (for example, stats.late_total_percent). Reflection made this very easy.</p></li>
</ol>
<p>So can anyone here give any examples from their own programming experiences of times when reflection has been helpful? The next time a co-worker asks me why I'd "ever want to do something like that" I'd like to be more prepared.</p>

<p>So if I have a method of parsing a text file and returning a <strong>list</strong> <em>of a</em> <strong>list</strong> <em>of</em> <strong>key value pairs</strong>, and want to create objects from the kvps returned (each list of kvps represents a different object), what would be the best method?</p>
<p>The first method that pops into mind is pretty simple, just keep a list of keywords:</p>
<pre><code>private const string NAME = "name";
private const string PREFIX = "prefix";
</code></pre>
<p>and check against the keys I get for the constants I want, defined above. This is a fairly core piece of the project I'm working on though, so I want to do it well; does anyone have any more robust suggestions (not saying there's anything inherently un-robust about the above method - I'm just asking around)?</p>
<h1>Edit:</h1>
<p>More details have been asked for. I'm working on a little game in my spare time, and I am building up the game world with configuration files. There are four - one defines all creatures, another defines all areas (and their locations in a map), another all objects, and a final one defines various configuration options and things that don't fit else where. With the first three configuration files, I will be creating objects based on the content of the files - it will be quite text-heavy, so there will be a lot of strings, things like names, plurals, prefixes - that sort of thing. The configuration values are all like so:</p>
<pre><code>-
key: value
key: value
-
key: value
key: value
-
</code></pre>
<p>Where the '-' line denotes a new section/object.</p>

<p>In my specific example, I'm dealing with a drop-down, e.g.:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><select name="foo" id="bar">
<option disabled="disabled" selected="selected">Select an item:</option>
<option>an item</option>
<option>another item</option>
</select></code></pre>
</div>
</div>
</p>
<p>Of course, that's pretty nonsensical, but I'm wondering whether any strict behaviour is defined. Opera effectively rejects the 'selected' attribute and selects the next item in the list. All other browsers appear to allow it, and it remains selected.</p>
<p><strong>Update:</strong> To clarify, I'm specifically interested in the initial selection. I'm dealing with one of those 'Select an item:'-type drop-downs, in which case the first option is really a label, and an action occurs <code>onchange()</code>. This is <em>fairly</em> well 'progressively enhanced', in that a submit button is present, and only removed via JavaScript. If the "select..." option were removed, whatever then were to become the first item would not be selectable. Are we just ruling out <code>onchange</code> drop downs altogether, or should the "select..." option be selectable, just with no effect?</p>

<p>I am sure a responsive UI is something that everyone strives for and the reccomended way to do stuff is to use the BackgroundWorker for this. </p>
<p>Do you find it easy to work with ? Do you use it often ? Or do you have your own frameworks for lengthy tasks and reporting process.</p>
<p>I have found that I am using it quite a lot and even using its delegates wherever I need some sort of progress reporting.</p>

<p>In my application I have a window which I popup with small messages on it (think similar to tooltip). This window uses the layered attributes to draw alpha backgrounds etc.</p>
<p>If I have several of these windows open at once, and I click one with my mouse, when they disappear they cause my application to lose focus (it switches focus to the app behind the current one).</p>
<p>How do I stop any interaction in my window?</p>

<p>I created a few mediawiki custom tags, using the guide found here</p>
<p><a href="http://www.mediawiki.org/wiki/Manual:Tag_extensions" rel="nofollow noreferrer">http://www.mediawiki.org/wiki/Manual:Tag_extensions</a></p>
<p>I will post my code below, but the problem is after it hits the first custom tag in the page, it calls it, and prints the response, but does not get anything that comes after it in the wikitext. It seems it just stops parsing the page.</p>
<p>Any Ideas?</p>
<pre><code>if ( defined( 'MW_SUPPORTS_PARSERFIRSTCALLINIT' ) ) {
$wgHooks['ParserFirstCallInit'][] = 'tagregister';
} else { // Otherwise do things the old fashioned way
$wgExtensionFunctions[] = 'tagregister';
}
function tagregister(){
global $wgParser;
$wgParser->setHook('tag1','tag1func');
$wgParser->setHook('tag2','tag2func');
return true;
}
function tag1func($input,$params)
{
return "It called me";
}
function tag2func($input,$params)
{
return "It called me -- 2";
}
</code></pre>
<p>Update: @George Mauer -- I have seen that as well, but this does not stop the page from rendering, just the Mediawiki engine from parsing the rest of the wikitext. Its as if hitting the custom function is signaling mediawiki that processing is done. I am in the process of diving into the rabbit hole but was hoping someone else has seen this behavior.</p>

<p>When connecting to remote hosts via ssh, I frequently want to bring a file on that system to the local system for viewing or processing. Is there a way to copy the file over without (a) opening a new terminal/pausing the ssh session (b) authenticating again to either the local or remote hosts which works (c) even when one or both of the hosts is behind a NAT router?</p>
<p>The goal is to take advantage of as much of the current state as possible: that there is a connection between the two machines, that I'm authenticated on both, that I'm in the working directory of the file---so I don't have to open another terminal and copy and paste the remote host and path in, which is what I do now. The best solution also wouldn't require any setup before the session began, but if the setup was a one-time or able to be automated, than that's perfectly acceptable. </p>

<p>We have an Apache ANT script to build our application, then check in the resulting JAR file into version control (VSS in this case). However, now we have a change that requires us to build 2 JAR files for this project, then check both into VSS.</p>
<p>The current target that checks the original JAR file into VSS discovers the name of the JAR file through some property. Is there an easy way to "generalize" this target so that I can reuse it to check in a JAR file with any name? In a normal language this would obviously call for a function parameter but, to my knowledge, there really isn't an equivalent concept in ANT.</p>

<p>Is there an open-source alternative to MATLAB's <a href="https://www.mathworks.com/help/optim/index.html;jsessionid=95cd06964ab253598de29e7d0a80" rel="nofollow noreferrer"><code>fmincon</code></a> function for constrained linear optimization? I'm rewriting a MATLAB program to use Python / <a href="https://numpy.org/" rel="nofollow noreferrer">NumPy</a> / <a href="https://scipy.org/" rel="nofollow noreferrer">SciPy</a> and this is the only function I haven't found an equivalent to. A NumPy-based solution would be ideal, but any language will do.</p>

<p>Had an interesting discussion with some colleagues about the best scheduling strategies for realtime tasks, but not everyone had a good understanding of the common or useful scheduling strategies.</p>
<p>For your answer, please choose one strategy and go over it in some detail, rather than giving a little info on several strategies. If you have something to add to someone else's description and it's short, add a comment rather than a new answer (if it's long or useful, or simply a much better description, then please use an answer)</p>
<ul>
<li>What is the strategy - describe the general case (assume people know what a task queue is, semaphores, locks, and other OS fundamentals outside the scheduler itself)</li>
<li>What is this strategy optimized for (task latency, efficiency, realtime, jitter, resource sharing, etc)</li>
<li>Is it realtime, or can it be made realtime</li>
</ul>
<p>Current strategies:</p>
<ul>
<li><a href="https://stackoverflow.com/questions/49962/task-schedulers#74894">Priority Based Preemptive</a></li>
<li><a href="https://stackoverflow.com/questions/49962/task-schedulers#50056">Lowest power slowest clock</a></li>

<p>I have tried <code>=COUNTIF(D3:D9,CELL("color",D3))</code> with no success (Where <code>D3</code> is red).</p>

<p>Occasionally a program on a Windows machine goes crazy and just hangs. So I'll call up the task manager and hit the "End Process" button for it. However, this doesn't always work; if I try it enough times then it'll usually die eventually, but I'd really like to be able to just kill it immediately. On Linux I could just <code>kill -9</code> to guarantee that a process will die.</p>
<p>This also could be used for writing batch scripts and writing batch scripts is programming.</p>
<p><strong>Is there some</strong> program or <strong>command that comes with Windows that will always kill a process?</strong> A free third-party app would be fine, although I'd prefer to be able to do this on machines I sit down at for the first time.</p>

<p>I have a weird bug involving Flash text and hyperlinks, htmlText in a TextField with <code><a></code> tags seem to truncate surrounding space:</p>
<p><a href="https://i.stack.imgur.com/FDA7a.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FDA7a.gif" alt="output"></a></p>
<p>Once I place my cursor over the text, it "fixes" itself:</p>
<p><a href="https://i.stack.imgur.com/YFbSR.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YFbSR.gif" alt="output with mouseover"></a></p>
<p>Here is the HTML in the textField:</p>
<pre><code><p>The speeches at both the <a href="http://www.demconvention.com/speeches/" target="_blank">Democratic National Convention</a> last week and the <a href="http://www.gopconvention2008.com/videos" target="_blank">Republican National Convention</a> this week, have been, for me at least, must see TV.</p>
</code></pre>
<p>When I disable the styleSheet attached to it, the effect still occurs, but placing my mouse over it does not fix the spacing. I am using "Anti-alias for readability", and have embedded the all Uppercase, Lowercase, Numerals, and Punctuation. I will also point out that if I change the rendering setting to "Use Device fonts" the bug goes away.</p>
<p>Any thoughts?</p>

<p>The .Net generated code for a form with the "DefaultButton" attribute set contains poor javascript that allows the functionality to work in IE but not in other browsers (Firefox specifcially). </p>
<p>Hitting enter key does submit the form with all browsers but Firefox cannot disregard the key press when it happens inside of a <textarea> control. The result is a multiline text area control that cannot be multiline in Firefox as the enter key submits the form instead of creating a new line. </p>
<p>For more information on the bug, <a href="http://www.velocityreviews.com/forums/t367383-formdefaultbutton-behaves-incorrectly.html" rel="noreferrer">read it here</a>.</p>
<p>This could be fixed in Asp.Net 3.0+ but a workaround still has to be created for 2.0. </p>
<p>Any ideas for the lightest workaround (a hack that doesn't look like a hack =D)? The solution in the above link scares me a little as it could easily have unintended side-effects.</p>

<pre><code>widget.setBackground( );
</code></pre>
<p>Except I have no idea how to create the color Object in SWT?</p>

<p>I know it is not recommended, but is it at all possible to pass the user's password to scp?</p>
<p>I'd like to copy a file via scp as part of a batch job and the receiving server does, of course, need a password and, no, I cannot easily change that to key-based authentication.</p>

<p>I would like to use an add-in like simple-modal or the dialog add-in in the UI kit. However, how do I use these or any other and get a result back. Basically I want the modal to do some AJAX interaction with the server and return the result for the calling code to do some stuff with.</p>

<p>I would like to compare two collections (in C#), but I'm not sure of the best way to implement this efficiently.</p>
<p>I've read the other thread about <a href="https://stackoverflow.com/questions/43500/is-there-a-built-in-method-to-compare-collections-in-c">Enumerable.SequenceEqual</a>, but it's not exactly what I'm looking for.</p>
<p>In my case, two collections would be equal if they both contain the same items (no matter the order).</p>
<p>Example:</p>
<pre><code>collection1 = {1, 2, 3, 4};
collection2 = {2, 4, 1, 3};
collection1 == collection2; // true
</code></pre>
<p>What I usually do is to loop through each item of one collection and see if it exists in the other collection, then loop through each item of the other collection and see if it exists in the first collection. (I start by comparing the lengths).</p>
<pre><code>if (collection1.Count != collection2.Count)
return false; // the collections are not equal
foreach (Item item in collection1)
{
if (!collection2.Contains(item))
return false; // the collections are not equal
}
foreach (Item item in collection2)
{
if (!collection1.Contains(item))
return false; // the collections are not equal
}
return true; // the collections are equal
</code></pre>
<p>However, this is not entirely correct, and it's probably not the most efficient way to do compare two collections for equality.</p>
<p>An example I can think of that would be wrong is:</p>
<pre><code>collection1 = {1, 2, 3, 3, 4}
collection2 = {1, 2, 2, 3, 4}
</code></pre>
<p>Which would be equal with my implementation. Should I just count the number of times each item is found and make sure the counts are equal in both collections?</p>
<hr>
<p>The examples are in some sort of C# (let's call it pseudo-C#), but give your answer in whatever language you wish, it does not matter.</p>
<p><strong>Note:</strong> I used integers in the examples for simplicity, but I want to be able to use reference-type objects too (they do not behave correctly as keys because only the reference of the object is compared, not the content).</p>

<p>If any of you have worked with a cool tool for viewing/querying the SQL Transaction logs, please let me know. This should show all the transactional sql statements which are committed or rolled back.</p>
<p>For Database files, if it has some additional graphical capabilities like showing the internal Binary Tree structure of the indexes, that will be awesome but I guess I am asking for too much huh..</p>

<p>I understand the value of the three-part service/host/client model offered by WCF. But is it just me or does it seem like WCF took something pretty direct and straightforward (the ASMX model) and made a mess out of it? </p>
<p>Is there an alternative to using SvcUtil's command line step back in time to generate the proxy? With ASMX services a test harness was automatically provided; is there a good alternative today with WCF? </p>
<p>I appreciate that the WS* stuff is more tightly integrated with WCF and hope to find some payoff for WCF there, but geeze, otherwise I'm perplexed. </p>
<p>Also, the state of books available for WCF is abysmal at best. Juval Lowy, a superb author, has written a good O'Reilly reference book "Programming WCF Services" but it doesn't do that much (for me anyway) for learning now to use WCF. That book's precursor (and a little better organized, but not much, as a tutorial) is Michele Leroux Bustamante's Learning WCF. It has good spots but is outdated in place and its corresponding Web site is gone. </p>
<p>Do you have good WCF learning references besides just continuing to Google the bejebus out of things?</p>

<p>So my site uses <a href="http://mjijackson.com/shadowbox/" rel="nofollow noreferrer">shadowbox</a> to do display some dynamic text. Problem is I need the user to be able to copy and paste that text. </p>
<p>Right-clicking and selecting copy works but <kbd>Ctrl</kbd>+<kbd>C</kbd> doesn't (no keyboard shortcuts do) and most people use <kbd>Ctrl</kbd>+<kbd>C</kbd>? You can see an example of what I'm talking about <a href="http://mjijackson.com/shadowbox/" rel="nofollow noreferrer">here</a>. </p>
<p>Just go to the "web" examples and click "inline". Notice keyboard shortcuts do work on the "this page" example. The only difference between the two I see is the player js files they use. "Inline" uses the html.js player and "this page" uses iframe.js. Also, I believe it uses the mootools library. Any ideas?</p>

<p>I know that it does in PHP, and I'm pretty sure it does in Java. I haven't used the latest versions of .NET, so I won't speak for them. It seems very awkward, but I was wondering if there was an underlying reason for this.</p>

<p>I wrote a SQL function to convert a datetime value in SQL to a friendlier "n Hours Ago" or "n Days Ago" etc type of message. And I was wondering if there was a better way to do it. </p>
<p>(Yes I know "don't do it in SQL" but for design reasons I have to do it this way).</p>
<p>Here is the function I've written:</p>
<pre><code>CREATE FUNCTION dbo.GetFriendlyDateTimeValue
(
@CompareDate DateTime
)
RETURNS nvarchar(48)
AS
BEGIN
DECLARE @Now DateTime
DECLARE @Hours int
DECLARE @Suff nvarchar(256)
DECLARE @Found bit
SET @Found = 0
SET @Now = getDate()
SET @Hours = DATEDIFF(MI, @CompareDate, @Now)/60
IF @Hours <= 1
BEGIN
SET @Suff = 'Just Now'
SET @Found = 1
RETURN @Suff
END
IF @Hours < 24
BEGIN
SET @Suff = ' Hours Ago'
SET @Found = 1
END
IF @Hours >= 8760 AND @Found = 0
BEGIN
SET @Hours = @Hours / 8760
SET @Suff = ' Years Ago'
SET @Found = 1
END
IF @Hours >= 720 AND @Found = 0
BEGIN
SET @Hours = @Hours / 720
SET @Suff = ' Months Ago'
SET @Found = 1
END
IF @Hours >= 168 AND @Found = 0
BEGIN
SET @Hours = @Hours / 168
SET @Suff = ' Weeks Ago'
SET @Found = 1
END
IF @Hours >= 24 AND @Found = 0
BEGIN
SET @Hours = @Hours / 24
SET @Suff = ' Days Ago'
SET @Found = 1
END
RETURN Convert(nvarchar, @Hours) + @Suff
END
</code></pre>

<p>I have several wpf pages with update/delete/add buttons. I want to display to the user messages like "successful delete", etc. How can I best implement this so the message is defined in a single place (similar to an asp.net master page) and I can update this message from anywhere?</p>

<p>I'd like to know which libraries are used by executables on my system. More specifically, I'd like to rank which libraries are used the most, along with the binaries that use them. How can I do this?</p>

<p>I have a query that looks like this:</p>
<pre><code>public IList<Post> FetchLatestOrders(int pageIndex, int recordCount)
{
DatabaseDataContext db = new DatabaseDataContext();
return (from o in db.Orders
orderby o.CreatedDate descending
select o)
.Skip(pageIndex * recordCount)
.Take(recordCount)
.ToList();
}
</code></pre>
<p>I need to print the information of the order and the user who created it:</p>
<pre><code>foreach (var o in FetchLatestOrders(0, 10))
{
Console.WriteLine("{0} {1}", o.Code, o.Customer.Name);
}
</code></pre>
<p>This produces a SQL query to bring the orders and one query for each order to bring the customer. Is it possible to optimize the query so that it brings the orders and it's customer in one SQL query?</p>
<p>Thanks</p>
<p>UDPATE: By suggestion of sirrocco I changed the query like this and it works. Only one select query is generated:</p>
<pre><code>public IList<Post> FetchLatestOrders(int pageIndex, int recordCount)
{
var options = new DataLoadOptions();
options.LoadWith<Post>(o => o.Customer);
using (var db = new DatabaseDataContext())
{
db.LoadOptions = options;
return (from o in db.Orders
orderby o.CreatedDate descending
select o)
.Skip(pageIndex * recordCount)
.Take(recordCount)
.ToList();
}
}
</code></pre>
<p>Thanks sirrocco.</p>

<p>I can't be sure if my code is sucking, or if it's just that the browsers haven't caught up with the spec yet.</p>
<p>My goal is to simulate list markers using generated content, so as to get e.g. continuation of the counters from list to list in pure CSS.</p>
<p>So the code below, which I <em>think</em> is correct according to <a href="http://www.w3.org/TR/CSS2/generate.html#markers" rel="nofollow noreferrer">the spec</a>, is like this:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>html {
counter-reset: myCounter;
}
li {
counter-increment: myCounter;
}
li:before {
content: counter(myCounter)". ";
display: marker;
width: 5em;
text-align: right;
marker-offset: 1em;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><ol>
<li>The<li>
<li>quick</li>
<li>brown</li>
</ol>
<ol>
<li>fox</li>
<li>jumped</li>
<li>over</li>
</ol></code></pre>
</div>
</div>
</p>
<p>But this doesn't seem to generate markers, in either FF3, Chrome, or IE8 beta 2, and if I recall correctly not Opera either (although I've since uninstalled Opera).</p>
<p>So, does anyone know if markers are <em>supposed</em> to work? Quirksmode.org isn't being its usual helpful self in this regard :(.</p>

<p>Is there a good library to use for gathering user input in Linux from the mouse/keyboard/joystick that doesn't force you to create a visible window to do so? SDL lets you get user input in a reasonable way, but seems to force you to create a window, which is troublesome if you have abstracted control so the control machine doesn't have to be the same as the render machine. However, if the control and render machines are the same, this results in an ugly little SDL window on top of your display.</p>
<p><strong>Edit To Clarify</strong>:<br>
The renderer has an output window, in its normal use case, that window is full screen, except when they are both running on the same computer, just so it is possible to give the controller focus. There can actually be multiple renderers displaying a different view of the same data on different computers all controlled by the same controller, hence the total decoupling of the input from the output (Making taking advantage of the built in X11 client/server stuff for display less useable) Also, multiple controller applications for one renderer is also possible. Communication between the controllers and renderers is via sockets.</p>

<p>I've got a number of non-technical users that all share a set of project files. It would be ideal to have them using version control, but I think that both subversion and git are too technical for non-technical office staff.</p>
<p>Is there any distributed source control software that would work well for normal people?</p>

<p>We're using Mercurial where I work and I want to have a setup similar to how I used SVN:</p>
<ul>
<li>Trunk</li>
<li>Tags
<ul>
<li>Production</li>
</ul></li>
<li>Branches</li>
</ul>
<p>Since Mercurial supports branches natively, I know how to create a named branch, but I can't find any documentation on how to repeatedly merge 'Trunk' with 'Production'. </p>
<p>Quite simply, I want to have a development branch for normal work and a production branch that I routinely pull changes from the development branch into. How do I do this with Mercurial?</p>

<p>Often time I need to add a control to a dialog after the dialog has been generated via dialog template and CreateDialogIndirect. In these cases the tab order is set by the dialog template and there is no obvious way to change the tab order by including a newly created control.</p>

<p>I'm stuck trying to create a dynamic linq extension method that returns a string in JSON format - I'm using System.Linq.Dynamic and Newtonsoft.Json and I can't get the Linq.Dynamic to parse the "cell=new object[]" part. Perhaps too complex? Any ideas? : </p>
<p><strong>My Main method:</strong></p>
<pre><code>static void Main(string[] args)
{
NorthwindDataContext db = new NorthwindDataContext();
var query = db.Customers;
string json = JSonify<Customer>

query,
2,
10,
"CustomerID"
,
new string[]
{
"CustomerID",
"CompanyName",
"City",
"Country",
"Orders.Count"
});
Console.WriteLine(json);
}
</code></pre>
<p><strong>JSonify class</strong></p>
<pre><code>public static class JSonify<T>

<p>I've been reading a lot lately about the next release of Java possibly supporting <a href="http://en.wikipedia.org/wiki/Closure_%28computer_science%29" rel="noreferrer">closures</a>. I feel like I have a pretty firm grasp on what closures are, but I can't think of a solid example of how they would make an Object-Oriented language "better". Can anyone give me a specific use-case where a closure would be needed (or even preferred)?</p>

<p>I have a site I made really fast that uses floats to display different sections of content. The floated content and the content that has an additional margin both appear fine in FF/IE, but on safari one of the divs is completely hidden. I've tried switching to <code>padding</code> and <code>position:relative</code>, but nothing has worked for me. If I take out the code to display it to the right it shows up again but under the floated content.</p>
<p>The main section of css that seems to be causing the problem is:</p>
<pre class="lang-css prettyprint-override"><code>#settings{
float:left;
}
#right_content{
margin-top:20px;
margin-left:440px;
width:400px;
}
</code></pre>
<p>This gives me the same result whether I specify a size to the #settings div or not. Any ideas would be appreciated.</p>
<p>The site is available at: <a href="http://frickinsweet.com/tools/Theme.mvc.aspx" rel="nofollow noreferrer">http://frickinsweet.com/tools/Theme.mvc.aspx</a> to see the source code.</p>

<p>I'm running some <a href="http://jakarta.apache.org/jmeter/" rel="noreferrer">JMeter</a> tests against a Java process to determine how responsive a web application is under load (500+ users). JMeter will give the response time for each web request, and I've written a script to ping the Tomcat Manager every X seconds which will get me the current size of the JVM heap.</p>
<p>I'd like to collect stats on the server of the % of CPU being used by Tomcat. I tried to do it in a shell script using <code>ps</code> like this:</p>
<pre><code>PS_RESULTS=`ps -o pcpu,pmem,nlwp -p $PID`
</code></pre>
<p>...running the command every X seconds and appending the results to a text file. (for anyone wondering, <code>pmem</code> = % mem usage and <code>nlwp</code> is number of threads)</p>
<p>However I've found that this gives a different definition of "% of CPU Utilization" than I'd like - according to the manpages for ps, <code>pcpu</code> is defined as:</p>
<blockquote>
<p>cpu utilization of the process in "##.#" format. It is the CPU time used divided by the time the process has been running (cputime/realtime ratio), expressed as a percentage. </p>
</blockquote>
<p>In other words, <code>pcpu</code> gives me the % CPU utilization for the process for the <em>lifetime</em> of the process.</p>
<p>Since I want to take a sample every X seconds, I'd like to be collecting the CPU utilization of the process at the current time only - similar to what <code>top</code> would give me
(CPU utilization of the process since the last update). </p>
<p>How can I collect this from within a shell script? </p>

<p>I have a couple of solutions, but none of them work perfectly.</p>
<p><strong>Platform</strong></p>
<ol>
<li>ASP.NET / VB.NET / .NET 2.0</li>
<li>IIS 6</li>
<li>IE6 (primarily), with some IE7; Firefox not necessary, but useful</li>
</ol>
<p><em>Allowed 3rd Party Options</em></p>
<ol>
<li>Flash</li>
<li>ActiveX (would like to avoid)</li>
<li>Java (would like to avoid)</li>
</ol>
<p><strong>Current Attempts</strong></p>
<p><em>Gmail Style</em>: You can use javascript to add new Upload elements (input type='file'), then upload them all at once with the click of a button. This works, but still requires a lot of clicks. (I was able to use an invisible ActiveX control to detect things like File Size, which would be useful.)</p>
<p><em>Flash Uploader</em>: I discovered a couple of Flash Upload controls that use a 1x1 flash file to act as the uploader, callable by javascript. (One such control is <a href="http://digitarald.de/project/fancyupload/" rel="nofollow noreferrer">FancyUpload</a>, another is <a href="http://www.sitepen.com/blog/2008/09/02/the-dojo-toolkit-multi-file-uploader/" rel="nofollow noreferrer">Dojo's Multiple File Uploader</a>, yet another is one by <a href="http://www.codeproject.com/KB/aspnet/FlashUpload.aspx" rel="nofollow noreferrer">darick_c at CodeProject</a>.) These excited me, but I quickly ran into two issues:</p>
<ol>
<li>Flash 10 will break the functionality that is used to call the multiple file upload dialogue box. The workaround is to use a transparent flash frame, or just use a flash button to call the dialogue box. That's not a huge deal. </li>
<li>The integrated windows authentication used on our intranet is not used when the Flash file attempts to upload the files, prompting the user for credentials. The workaround for this is to use cookieless sessions, which would be a nightmare for our project due to several other reasons.</li>
</ol>
<p><em>Java Uploader</em>: I noticed several Java-based multiple-file uploaders, but most of the appear to cost money. If I found one that worked really well, I could arrange to purchase it. I'd just rather not. I also don't like the look of most of them. I liked FancyUpload because it interacted with html/javascript so that I could easily style and manage it any way I want. </p>
<p><em>ActiveX Uploader</em>: I found <a href="http://support.persits.com/xupload/demo1.asp" rel="nofollow noreferrer">an ActiveX solution</a> as well. It appears that ActiveX will work. I would just write my own instead of buying that one. This will be my last resort, I think.</p>
<p><strong>Resolution</strong></p>
<p>I would love to be able to use something like FancyUpload. If I can just get by the credentials prompt some way, it would be perfect. But, from my research, it appears that the only real workaround is cookieless sessions, which I just can't do. </p>
<p>So, the question is: Is there a way to resolve the issues presented above OR is there a different solution that I have not listed which accomplishes the same goal?</p>

<p>I'm developing a website. I'm using a single-page web-app style, so all of the different parts of the site are AJAX'd into index.php. When a user logs in and tells Firefox to remember his username and password, all input boxes on the site get auto-filled with that username and password. This is a problem on the form to change a password. How can i prevent Firefox from automatically filling out these fields? I already tried giving them different names and ids.</p>
<p>Edit: <a href="https://stackoverflow.com/questions/32369/disable-browser-save-password-functionality">Someone has already asked this</a>. Thanks Joel Coohorn.</p>

<p>I'm trying to implement Drag & Drop functionality with source being a TreeView control. When I initiate a drag on a node, I'm getting:</p>
<p><em>Invalid FORMATETC structure (Exception from HRESULT: 0x80040064 (DV_E_FORMATETC))</em></p>
<p>The ItemDrag handler (where the exception takes place), looks like:</p>
<pre><code>private void treeView_ItemDrag(object sender,
System.Windows.Forms.ItemDragEventArgs e)
{
this.DoDragDrop(e.Item, DragDropEffects.Move);
}
</code></pre>
<p>Does anyone know the root cause of this and how to remedy it? (.NET 2.0, Windows XP SP2)</p>

<p>I'm trying to mixin the <code>MultiMap</code> trait with a <code>HashMap</code> like so:</p>
<pre><code>val children:MultiMap[Integer, TreeNode] =
new HashMap[Integer, Set[TreeNode]] with MultiMap[Integer, TreeNode]
</code></pre>
<p>The definition for the <code>MultiMap</code> trait is:</p>
<pre><code>trait MultiMap[A, B] extends Map[A, Set[B]]
</code></pre>
<p>Meaning that a <code>MultiMap</code> of types <code>A</code> & <code>B</code> is a <code>Map</code> of types <code>A</code> & <code>Set[B]</code>, or so it seems to me. However, the compiler complains:</p>
<pre><code>C:\...\TestTreeDataModel.scala:87: error: illegal inheritance; template $anon inherits different type instances of trait Map: scala.collection.mutable.Map[Integer,scala.collection.mutable.Set[package.TreeNode]] and scala.collection.mutable.Map[Integer,Set[package.TreeNode]]
new HashMap[Integer, Set[TreeNode]] with MultiMap[Integer, TreeNode]
^ one error found
</code></pre>
<p>It seems that generics are tripping me up again.</p>

<p>I'm using <a href="http://en.wikipedia.org/wiki/Windows_Script_Host#Usage" rel="noreferrer">WScript</a> to automate some tasks, by using WScript.Shell to call external programs.</p>
<p>However, right now it does not wait for the external program to finish, and instead moves on. This causes issues because I have some tasks dependent on others finishing first.</p>
<p>I am using code like:</p>
<pre><code>ZipCommand = "7za.exe a -r -y " & ZipDest & BuildLabel & ".zip " & buildSourceDir
Set wshShell = WScript.CreateObject("Wscript.Shell")
wshShell.run ZipCommand
</code></pre>
<p>Is there a way to do this so it blocks until the shell executed program returns?</p>

<p>I'm trying to get a webservice up and running that actually requires to check whois databases. What I'm doing right now is ugly and I'd like to avoid it as much as I can: I call gwhois command and parse its output. Ugly.</p>
<p>I did some search to try to find a pythonic way to do this task. Generally I got quite much nothing - <a href="http://mail.python.org/pipermail/python-list/2000-March/028122.html" rel="noreferrer">this old discussion list link</a> has a way to check if domain exist. Quite not what I was looking for... But still, it was best anwser Google gave me - everything else is just a bunch of unanwsered questions.</p>
<p>Any of you have succeeded to get some method up and running? I'd very much appreciate some tips, or should I just do it the opensource-way, sit down and code something by myself? :) </p>

<p>I have a few controls that inherit from <code>ASP.NET buttons</code> and use <code>onserverclick</code>.</p>
<p>If the user clicks twice, the button fires two server side events. How can I prevent this?</p>
<p>I tried setting <code>this.disabled='true'</code> after the click (in the <code>onclick</code> attribute) via javascript, but that blocks the first postback as well.</p>

<p>This has been driving me crazy for a few days. Why doesn't the following work?</p>
<blockquote>
<pre><code> Dim arr(3, 3) As Integer
For y As Integer = 0 To arr.GetLength(0) - 1
For x As Integer = 0 To arr.GetLength(y) - 1
arr(y, x) = y + x
Next
Next
</code></pre>
</blockquote>
<p>Also, what if the array looked like this instead?</p>
<pre><code>{ {1, 2, 3},
{4, 5, 6, 7, 8, 9, 9, 9},
{5, 4, 3, 2}

<p>Is there a good way to adjust the size of a <code>UITextView</code> to conform to its content? Say for instance I have a <code>UITextView</code> that contains one line of text:</p>
<pre><code>"Hello world"
</code></pre>
<p>I then add another line of text:</p>
<pre><code>"Goodbye world"
</code></pre>
<p>Is there a good way in Cocoa Touch to get the <code>rect</code> that will hold all of the lines in the text view so that I can adjust the parent view accordingly?</p>
<p>As another example, look at the notes' field for events in the Calendar application - note how the cell (and the <code>UITextView</code> it contains) expands to hold all lines of text in the notes' string.</p>

<p>I have scripts calling other script files but I need to get the filepath of the file that is currently running within the process. </p>
<p>For example, let's say I have three files. Using <a href="http://docs.python.org/library/functions.html#execfile" rel="noreferrer">execfile</a>:</p>
<ul>
<li><code>script_1.py</code> calls <code>script_2.py</code>. </li>
<li>In turn, <code>script_2.py</code> calls <code>script_3.py</code>. </li>
</ul>
<p>How can I get the file name and path of <strong><code>script_3.py</code></strong>, <em>from code within <code>script_3.py</code></em>, without having to pass that information as arguments from <code>script_2.py</code>?</p>
<p>(Executing <code>os.getcwd()</code> returns the original starting script's filepath not the current file's.)</p>

<p>Let's take the code</p>
<pre><code>int a, b, c;
...
if ((a + b) > C)
</code></pre>
<p>If we add the values of a and b and the sum exceeds the maximum value of an int, will the integrity of the comparison be compromised? I was thinking that there might be an implicit up cast or overflow bit check and that will be factored into the evaluation of this expression.</p>

<p>So I was reading those Windows Vista UI guidelines someone linked to in another question, and they mentioned that you should be able to survive a switch to 120 DPI. Well, I fire up my handy VM with my app installed, and what do we get... AAAAGH!!! MASSIVE UI FAIL!</p>
<p>Everything's all jumbled: some containers aren't big enough for their text; some controls that were positioned "next to each other" are now all squished together/spread apart; some buttons aren't tall enough; my <code>ListView</code> columns aren't wide enough... eeek.</p>
<p>It sounds like a completely different approach is in order. My previous one was basically using the VS2008 Windows Forms designer to create, I guess, a pixel-based layout. I can see that if I were to stick with Windows Forms, <code>FlowLayoutPanel</code>s would be helpful, although I've found them rather inflexible in the past. They also don't solve the problem where the containers (e.g. the form itself) aren't big enough; presumably there's a way to do that? Maybe that <code>AutoSize</code> property?</p>
<p>This might also be a sign that it's time to jump ship to WPF; I'm under the impression that it's specifically designed for this kind of thing.</p>
<p>The basic issue seems to come down to these:</p>
<ul>
<li>If I were to stick with Windows Forms, what are all the tricks to achieving a font-size-independent layout that can survive the user setting his fonts large, or setting the display to 120 DPI?</li>
<li>Does WPF have significant advantages here, and if so, can you try to convince me that it's worth the switch?</li>
<li>Are there any general "best-practices" for font-size-independent layouts, either in the .NET stack or in general?</li>
</ul>

<p>How do I format a number in Java?<br />
What are the "Best Practices"?</p>
<p>Will I need to round a number before I format it?</p>
<blockquote>
<p><code>32.302342342342343</code> => <code>32.30</code></p>
<p><code>.7323</code> => <code>0.73</code></p>

<p>One of the guys I work with needs a custom control that would work like a multiline ddl since such a thing does not exist as far as we have been able to discover</p>
<p>does anyone have any ideas or have created such a thing before<br>
we have a couple ideas but they involve to much database usage </p>
<p>We prefer that it be FREE!!!</p>

<p>I have a two dimensional array that I need to load data into. I know the width of the data (22 values) but I do not know the height (estimated around 4000 records, but variable).</p>
<p>I have it declared as follows: </p>
<pre><code>float[,] _calibrationSet;
....
int calibrationRow = 0;
While (recordsToRead)
{
for (int i = 0; i < SensorCount; i++)
{
_calibrationSet[calibrationRow, i] = calibrationArrayView.ReadFloat();
}
calibrationRow++;
}
</code></pre>
<p>This causes a NullReferenceException, so when I try to initialize it like this: </p>
<pre><code>_calibrationSet = new float[,];
</code></pre>
<p>I get an "Array creation must have array size or array initializer."</p>
<p>Thank you,
Keith</p>

<p>I need to come up with an analysis of simultaneus events, when having only starttime and duration of each event.</p>
<p><strong>Details</strong></p>
<p>I've a standard CDR call detail record, that contains among others:</p>
<ul>
<li>calldate (timedate of each call start</li>
<li>duration (int, seconds of call duration)</li>
<li>channel (a string)</li>
</ul>
<p>What I need to come up with is some sort of analysys of simultaneus calls on each second, for a given timedate period. For example, a graph of simultaneous calls we had yesterday.</p>
<p>(The problem is the same if we have visitors logs with duration on a website and wish to obtain simultaneous clients for a group of web-pages)</p>
<p>What would your algoritm be?</p>
<p>I can iterate over records in the given period, and fill an array, where each bucket of the array corresponds to 1 second in the overall period. This works and seems to be fast, but if the timeperiod is big (say..1 year), I would need lots of memory (3600x24x365x4 bytes ~ 120MB aprox).</p>
<p>This is for a web-based, interactive app, so my memory footprint should be small enough. </p>
<p><strong>Edit</strong></p>
<p>By simultaneous, I mean all calls on a given second. Second would be my minimum unit. I cannot use something bigger (hour for example) becuse all calls during an hour do not need to be held at the same time.</p>

<p>I'm having a strange problem.</p>
<p>I have to use <code>GetPostBackEventRefence</code> to force a Postback, but it works the first time, after the first postback, the .NET function is not rendered... any ideas?</p>
<p>This is what I'm missing after the postback:</p>
<pre><code><script language="javascript" type="text/javascript">
<!--
function __doPostBack(eventTarget, eventArgument) {
var theform;
if (window.navigator.appName.toLowerCase().indexOf("microsoft") > -1) {
theform = document.Main;
}
else {
theform = document.forms["Main"];
}
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->
</script>
</code></pre>

<p>How do you capture the mouse events, move and click over top of a Shockwave Director Object (not flash) in Firefox, via JavaScript. The code works in IE but not in FF. </p>
<p>The script works on the document body of both IE and Moz, but mouse events do not fire when mouse is over a shockwave director object embed.</p>
<p>Update: </p>
<pre><code> function displaycoordIE(){
window.status=event.clientX+" : " + event.clientY;
}
function displaycoordNS(e){
window.status=e.clientX+" : " + e.clientY;
}
function displaycoordMoz(e)
{
window.alert(e.clientX+" : " + e.clientY);
}
document.onmousemove = displaycoordIE;
document.onmousemove = displaycoordNS;
document.onclick = displaycoordMoz;
</code></pre>
<hr>
<p>Just a side note, I have also tried using an addEventListener to "mousemove".</p>

<p>Suppose I have the following C code.</p>
<pre><code>unsigned int u = 1234;
int i = -5678;
unsigned int result = u + i;
</code></pre>
<p>What implicit conversions are going on here, and is this code safe for all values of <code>u</code> and <code>i</code>? (Safe, in the sense that even though <em>result</em> in this example will overflow to some huge positive number, I could cast it back to an <em>int</em> and get the real result.)</p>

<p>I'm designing an application which includes the need to log all incoming messages I receive from a Telnet connection. The text is largely plain though can include ANSI tags that provide text colour and formatting (16 colours, bold, underline, etc).</p>
<p>I'm would like to format my logs to store the text with formatting, date/time and potentially other meta data later. My first thoughts was all XML but this could impact my ability to write a fast search tool later. My current idea is Date/Time + text in one file with meta-data stored in another XML file, referenced by line number.</p>
<p>Is this a good solution? Also, where and how should I store the formatting commands? The original ANSI tags would disrupt the plain but having them in two different files might be awkward.</p>
<p>Additional: Thanks to some answers so far, though I should mention that most of the time the messages will be person to person communications rather than system messages. A more primitive IRC of sorts. Its up to my user to decide later (by adding meta data) which messages were important. This is the raw on the record log that filtered or edited logs might derive from.</p>

<p>I was browsing <a href="https://stackoverflow.com/questions/5119/what-are-the-best-rss-feeds-for-programmersdevelopers">this thread</a>, which has good recommendation but a bit too general for me.</p>
<p>So, if anyone has a collection of nice game programming feeds,please share them. :)</p>
<p>(both general and specific topics are welcome)</p>

<p>Is there a way to have TortoiseSVN (or any other tool) auto-add any new .cs files I create within a directory to my working copy so I don't have to remember which files I created at the end of the day?</p>

<p>What's the simplest way of blocking a thread until a file has been unlocked and is accessible for reading and renaming? For example, is there a WaitOnFile() somewhere in the .NET Framework?</p>
<p>I have a service that uses a FileSystemWatcher to look for files that are to be transmitted to an FTP site, but the <em>file created</em> event fires before the other process has finished writing the file.</p>
<p>The ideal solution would have a timeout period so the thread doesn't hang forever before giving up.</p>
<p>Edit: After trying out some of the solutions below, I ended up changing the <em>system</em> so that all files wrote to <code>Path.GetTempFileName()</code>, then performed a <code>File.Move()</code> to the final location. As soon as the <code>FileSystemWatcher</code> event fired, the file was already complete.</p>

<p>We are using VS 2008 Team System with the automated test suite, and upon running tests the test host "randomly" locks up. I actually have to kill the VSTestHost process and re-run the tests to get something to happen, otherwise all tests sit in a "pending" state.</p>
<p>Has anyone experience similar behavior and know of a fix? We have 3 developers here experiencing the same behavior.</p>

<p>I don't want to specify an account in the ODBC connection, I want to do it on the ms-access side to hide it from my users. Doing it in the ODBC connection would put me right back in to the original situation I'm trying to avoid.</p>

<p>How does Google manage to properly align the second column <em>(i.e. the ticker name)</em> in the "Get Quotes" search box suggestion drop-down in <a href="http://finance.google.com" rel="nofollow noreferrer">google finance url</a></p>
<p><strong>Example:</strong> If you enter <code>iii</code> - the second column is perfectly aligned.</p>
<p>It does not use a fixed width font - so just adding the correct numbers of spaces to the <em>ticker</em> will not work.</p>
<p>How do they do that?

<p>Do any editors honer C #line directives with regards to goto line features?</p>
<p><em>Context:</em>
I'm working on a code generator and need to jump to a line of the output but the line is specified relative to the the #line directives I'm adding.
I can drop them but then finding the input line is even a worse pain</p>

<p>I wrote a simple tool to generate a DBUnit XML dataset using queries that the user enters. I want to include each query entered in the XML as a comment, but the DBUnit API to generate the XML file doesn't support inserting the comment where I would like it (above the data it generates), so I am resorting to putting the comment with ALL queries either at the top or bottom.</p>
<p>So my question: is it valid XML to place it at either location? For example, above the XML Declaration:</p>
<pre><code><!-- Queries used: ... -->
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
...
</dataset>
</code></pre>
<p>Or below the root node:</p>
<pre><code><?xml version='1.0' encoding='UTF-8'?>
<dataset>
...
</dataset>
<!-- Queries used: ... -->
</code></pre>
<p>I plan to initially try above the XML Declaration, but I have doubts on if that is valid XML, despite the claim from <a href="http://en.wikipedia.org/wiki/Xml#Well-formed_documents:_XML_syntax" rel="noreferrer">wikipedia</a>:</p>
<blockquote>
<p>Comments can be placed anywhere in the tree, including in the text if the content of the element is text or #PCDATA.</p>
</blockquote>
<p>I plan to post back if this works, but it would be nice to know if it is an official XML standard.</p>
<p><strong>UPDATE:</strong> See <a href="https://stackoverflow.com/questions/50824/can-xml-comments-go-anywhere#50976">my response below</a> for the result of my test.</p>

<p>This is a bit hypothetical and grossly simplified but...</p>
<p>Assume a program that will be calling functions written by third parties. These parties can be assumed to be non-hostile but can't be assumed to be "competent". Each function will take some arguments, have side effects and return a value. They have no state while they are not running.</p>
<p>The objective is to ensure they can't cause memory leaks by logging all mallocs (and the like) and then freeing everything after the function exits.</p>
<p>Is this possible? Is this practical?</p>
<p>p.s. The important part to me is ensuring that no allocations persist so ways to remove memory leaks without doing that are not useful to me.</p>

<p>I have a relationship between two entities (e1 and e2) and e1 has a collection of e2, however I have a similar relationship set up between (e2 and e3), yet e2 does not contain a collection of e3's, any reason why this would happen? Anything I can post to make this easier to figure out?</p>
<p>Edit: I just noticed that the relationship between e1 and e2 is solid and between e2 and e3 is dotted, what causes that? Is it related?</p>

<p>So I have about 10 short css files that I use with mvc app.
There are like
error.css
login.css
etc...
Just some really short css files that make updating and editing easy (At least for me). What I want is something that will optimize the if else branch and not incorporate it within the final bits. I want to do something like this</p>
<pre><code>if(Debug.Mode){
<link rel="stylesheet" type="text/css" href="error.css" />
<link rel="stylesheet" type="text/css" href="login.css" />
<link rel="stylesheet" type="text/css" href="menu.css" />
<link rel="stylesheet" type="text/css" href="page.css" />
} else {
<link rel="stylesheet" type="text/css" href="site.css" />
}
</code></pre>
<p>I'll have a msbuild task that will combine all the css files, minimize them and all that good stuff. I just need to know if there is a way to remove the if else branch in the final bits.</p>

<p>I'm using <a href="http://www.helicontech.com/isapi_rewrite/" rel="nofollow noreferrer">Helicon's ISAPI Rewrite 3</a>, which basically enables .htaccess in IIS. I need to redirect a non-www URL to the www version, i.e. example.com should redirect to www.example.com. I used the following rule from the examples but it affects subdomains:</p>
<pre><code>RewriteCond %{HTTPS} (on)?
RewriteCond %{HTTP:Host} ^(?!www\.)(.+)$ [NC]
RewriteCond %{REQUEST_URI} (.+)
RewriteRule .? http(?%1s)://www.%2%3 [R=301,L]
</code></pre>
<p>This works for most part, but is also redirect sub.example.com to www.sub.example.com. How can I rewrite the above rule so that subdomains do not get redirected?</p>

<p>I liked the discussion at <a href="https://stackoverflow.com/questions/31693/differences-in-generics">Differences in Generics</a>, and was wondering whether there were any languages that used this feature particularly well.</p>
<p>I really dislike Java's <code>List<? extends Foo></code> for a <code>List</code> of things that are Liskov-substitutable for <code>Foo</code>. Why can't <code>List<Foo></code> cover that?</p>
<p>And honestly, <code>Comparable<? super Bar></code>?</p>
<p>I also can't remember for the life of my why you should never return an Array of generics:</p>
<pre><code>public T[] getAll<T>() { ... }
</code></pre>
<p>I never liked templates in C++, but that was mostly because none of the compilers could ever spit out a remotely meaningful error message for them. One time I actually did a <code>make realclean && make</code> 17 times to get something to compile; I never did figure out why the 17th time was the charm.</p>
<p>So, who actually <em>likes</em> using generics in their pet language?</p>

<p>I'm a C# developer who's fumbling in the first VB code he's written since VB6, so if I am asking a rather obvious question, please forgive me.</p>
<p>I decided to experiment with XML Literals to generate some XML code for me, instead of using XMLDocument</p>
<p>I have 2 questions, the second regarding a workaround due to my inability to figure out the first.</p>
<p>1: Ideal solution</p>
<p>I have a Dictionary of ElementName, ElementValue whose KeyValue pairs I was looping over in the hope of generating the values dynamically, but the following syntax dies a horrible death</p>
<pre><code>Dim xConnections As XElement
For Each connection As Connection In connections.AsList
For Each kvp As KeyValuePair(Of String, String) In connection.DecompiledElements
xConnections = <Connections> <<%= kvp.Key %>><%= kvp.Value %><\<%=kvp.Key %>> </Connections>
Next
Next
</code></pre>
<p>I have vague memories of the T4 syntax (the <%=%> syntax) being able to handle more complex operations (rather than direct assignment to the <%= ) and a 'Response.Write' like object to write output to, but I can't remember the details.</p>
<p>2: Cludgy workaround</p>
<p>Instead I thought of building a StringBuilder object and assigning its .ToString to the XElement, but that also failed with a conversion error.</p>
<p>I would prefer to continue using my key value pair concept in example one above, as I feel cludging together a string as in example 2 above is rather nasty, and I really should go back to using XMLDocument if instead.</p>
<p>Any thoughts or assistance greatly appreciated</p>

<p>One of the things I miss the most in ActionScript is the lack of operator overloading, in particular ==. I kind of work around this issue by adding a "Compare" method to my classes, but that doesn't help in many cases, like when you want to use things like the built in Dictionary.</p>
<p>Is there a good way to work around this problem?</p>

<p>I have 2 time values which have the type <code>datetime.time</code>. I want to find their difference. The obvious thing to do is t1 - t2, but this doesn't work. It works for objects of type <code>datetime.datetime</code> but not for <code>datetime.time</code>. So what is the best way to do this?</p>

<p>I have some HTML that is generated via a Rich Text Editor outside of my Flex application but would like to display it inside Flex. </p>
<p>The HTML is simple HTML tags, things like styles, anchors, and possibly image tags, is there a control that would let me render this HTML in flex or am I going to have to roll up my sleeves and roll my own?</p>
<p>Any ideas appreciated...Thanks.</p>

<p>How can you determine the performance consequences of your PHP code if you are not familiar with the internals? Are there ways to figure out how your code is being executed (besides simply load testing it)? I am looking for things like memory usage, the execution time for algorithms.</p>
<p>Perhaps Joel would say, "learn C, then read the internals", but I really don't have time to learn C right now (though I'd love to, actually). </p>
