94,331 | <p>I use the recent Ganymede release of Eclipse, specifically the distro for Java EE and web developers. I have installed a few additional plugins (e.g. Subclipse, Spring, FindBugs) and removed all the Mylyn plugins. </p>
<p>I don't do anything particularly heavy-duty within Eclipse such as starting an app server or connecting to databases, yet for some reason, after several hours use I see that Eclipse is using close to 500MB of memory.</p>
<p>Does anybody know why Eclipse uses so much memory (leaky?), and more importantly, if there's anything I can do to improve this?</p>

94,361 | <p>What are the best practices for using Java's <code>@Override</code> annotation and why? </p>
<p>It seems like it would be overkill to mark every single overridden method with the <code>@Override</code> annotation. Are there certain programming situations that call for using the <code>@Override</code> and others that should never use the <code>@Override</code>? </p>

94,382 | <p>I'm using gvim on Windows.</p>
<p>In my _vimrc I've added:</p>
<pre><code>set shell=powershell.exe
set shellcmdflag=-c
set shellpipe=>
set shellredir=>
function! Test()
echo system("dir -name")
endfunction
command! -nargs=0 Test :call Test()
</code></pre>
<p>If I execute this function (:Test) I see nonsense characters (non number/letter ASCII characters).</p>
<p>If I use cmd as the shell, it works (without the -name), so the problem seems to be with getting output from powershell into vim. </p>
<p>Interestingly, this works great:</p>
<pre><code>:!dir -name
</code></pre>
<p>As does this:</p>
<pre><code>:r !dir -name
</code></pre>
<p><strong>UPDATE:</strong> confirming behavior mentioned by <a href="https://stackoverflow.com/questions/94382/vim-with-powershell#101743">David</a></p>
<p>If you execute the set commands mentioned above in the _vimrc, :Test outputs nonsense. However, if you execute them directly in vim instead of in the _vimrc, :Test works as expected.</p>
<p>Also, I've tried using iconv in case it was an encoding problem:</p>
<pre><code>:echo iconv( system("dir -name"), "unicode", &enc )
</code></pre>
<p>But this didn't make any difference. I could be using the wrong encoding types though.</p>
<p>Anyone know how to make this work?</p>

<p>Does anyone have any thoughts/experience with doing this?</p>
<p>Minor clarification:
My intention was to use Windsor to intercept 'expensive' calls and delegate to MemCacheD or Velocity (or another distributed cache) for the caching itself.</p>

94,420 | <p>So I have a form that uses infopath services via sharepoint, and after multiple attempts at attempting to fix a rendering problem (tables appear WAY too wide to be readable), I think I have found the problem : date controls.</p>
<p>It seems date controls within Infopath 2007 screw with rendering somehow. To test, I made 2 variations of a VERY simple form - one with a date control, one with a text control - and placed them inside a table.</p>
<p>When emailed, the one with the date control rendered incorrectly.</p>
<p>My question is - has anyone experienced this before? If you have time, test it out. I think it is a bug or something, but not exactly sure.</p>
<p>I am using Infopath 2007, Sharepoint 2007, and Outlook 2007.</p>
<hr>
<h2><strong>Updated Sept 19, 2008</strong></h2>
<p>Yes, web form capability is checked.
Web compatible date controls? I think so - everything looks perfect in the browser... only the email messes up.
and yes you are correct. My mistake this is Sharepoint 2007. I fixed it above.</p>
<p>If anyone has the time, try it out - it's very frustrating to have to use text boxes for dates. Especially with the 'talent' we have here. lol</p>

94,488 | <p>More specifically, when the exception contains custom objects which may or may not themselves be serializable.</p>
<p>Take this example:</p>
<pre><code>public class MyException : Exception
{
private readonly string resourceName;
private readonly IList<string> validationErrors;
public MyException(string resourceName, IList<string> validationErrors)
{
this.resourceName = resourceName;
this.validationErrors = validationErrors;
}
public string ResourceName
{
get { return this.resourceName; }
}
public IList<string> ValidationErrors
{
get { return this.validationErrors; }
}
}
</code></pre>
<p>If this Exception is serialized and de-serialized, the two custom properties (<code>ResourceName</code> and <code>ValidationErrors</code>) will not be preserved. The properties will return <code>null</code>.</p>
<p><strong>Is there a common code pattern for implementing serialization for custom exception?</strong></p>

<p>Regex:</p>
<pre><code>$ perl -nE"say $1 if m~<div[^>]*>(.*?)</div>~" lt.html

<p>And screen-scraper:</p>
<pre><code>#!/usr/bin/env python
import sys
import BeautifulSoup
soup = BeautifulSoup.BeautifulSoup(sys.stdin)
for div in soup.findAll('div'):

I can get Cobertura to run on the child projects, but it erroneously reports 0% coverage, even though the reports still highlight the lines of code that were hit by the unit tests. </p>
<p>We are using mvn 2.0.8. I have tried running <code>mvn clean site</code>, <code>mvn clean site:stage</code> and <code>mvn clean package site</code>. I know the tests are running, they show up in the surefire reports (both the txt/xml and site reports). Am I missing something in the configuration?

94,594 | <p>I'm implementing a simple service using datagrams over unix local sockets (AF_UNIX address family, i.e. <strong>not UDP</strong>). The server is bound to a public address, and it receives requests just fine. Unfortunately, when it comes to answering back, <code>sendto</code> fails unless the client is bound too. (the common error is <code>Transport endpoint is not connected</code>).</p>
<p>Binding to some random name (filesystem-based or abstract) works. But I'd like to avoid that: who am I to guarantee the names I picked won't collide?</p>
<p>The unix sockets' stream mode documentation tell us that an abstract name will be assigned to them at <code>connect</code> time if they don't have one already. Is such a feature available for datagram oriented sockets?</p>

94,610 | <p>I have a Silverlight 2 application that is consuming a WCF service. As such, it uses asynchronous callbacks for all the calls to the methods of the service. If the service is not running, or it crashes, or the network goes down, etc before or during one of these calls, an exception is generated as you would expect. The problem is, I don't know how to catch this exception.</p>
<ul>
<li><p>Because it is an asynchronous call, I can't wrap my begin call with a try/catch block and have it pick up an exception that happens after the program has moved on from that point.</p></li>
<li><p>Because the service proxy is automatically generated, I can't put a try/catch block on each and every generated function that calls EndInvoke (where the exception actually shows up). These generated functions are also surrounded by External Code in the call stack, so there's nowhere else in the stack to put a try/catch either.</p></li>
<li><p>I can't put the try/catch in my callback functions, because the exception occurs before they would get called.</p></li>
<li><p>There is an Application_UnhandledException function in my App.xaml.cs, which captures all unhandled exceptions. I could use this, but it seems like a messy way to do it. I'd rather reserve this function for the truly unexpected errors (aka bugs) and not end up with code in this function for every circumstance I'd like to deal with in a specific way.</p></li>
</ul>
<p>Am I missing an obvious solution? Or am I stuck using Application_UnhandledException?</p>
<p>[Edit]<br>
As mentioned below, the Error property is exactly what I was looking for. What is throwing me for a loop is that the fact that the exception is thrown and appears to be uncaught, yet execution is able to continue. It triggers the Application_UnhandledException event and causes VS2008 to break execution, but continuing in the debugger allows execution to continue. It's not really a problem, it just seems odd.</p>

94,612 | <p>To elaborate ..
a) A table (BIGTABLE) has a capacity to hold a million rows with a primary Key as the ID. (random and unique)
b) What algorithm can be used to arrive at an ID that has not been used so far. This number will be used to insert another row into table BIGTABLE.</p>
<p>Updated the question with more details..
C) This table already has about 100 K rows and the primary key is not an set as identity.
d) Currently, a random number is generated as the primary key and a row inserted into this table, if the insert fails another random number is generated. the problem is sometimes it goes into a loop and the random numbers generated are pretty random, but unfortunately, They already exist in the table. so if we re try the random number generation number after some time it works.
e) The sybase rand() function is used to generate the random number.</p>
<p>Hope this addition to the question helps clarify some points.</p>

94,667 | <p>How can I bind an array parameter in the HQL editor of the HibernateTools plugin?
The query parameter type list does not include arrays or collections.</p>
<p>For example:<br>

How can I bind an array to that listOfValues?</p>

94,674 | <p>How come this doesn't work (operating on an empty select list <code><select id="requestTypes"></select></code></p>
<pre><code>$(function() {

function showRequestTypes(data, textStatus) {
$.each(data,
function() {
var option = new Option(this.RequestTypeName, this.RequestTypeID);

var dropdownList = $("#requestTypes");
if ($.browser.msie) {

<p>But this does:</p>
<ul>
<li><p>Replace:</p>

94,684 | <p>We are trying to integrate tests in our daily builds using TestComplete, so far we have a machine dedicated for testing and our build script copies to this machine everything TestComplete needs for its tests (Application, Database, Test script project and source files, etc).</p>
<p>Basically we can open the TestComplete project manually and run the tests.</p>
<p>Now we want to automate that process, so how do you do it? Or how do you think would be the simplest and best way to make this automation?</p>
<p>Keeping it short, we want to automate the process of opening TestComplete after each build, run all the tests and send an email with the test results.</p>
<p>Anyone can share some experience about this?</p>
<p>Thanks.</p>

94,755 | <p>What is the best way (in C++) to set up a container allowing for double-indexing? Specifically, I have a list of objects, each indexed by a key (possibly multiple per key). This implies a multimap. The problem with this, however, is that it means a possibly worse-than-linear lookup to find the location of an object. I'd rather avoid duplication of data, so having each object maintain it's own coordinate and have to move itself in the map would be bad (not to mention that moving your own object may indirectly call your destructor whilst in a member function!). I would rather some container that maintains an index both by object pointer and coordinate, and that the objects themselves guarantee stable references/pointers. Then each object could store an iterator to the index (including the coordinate), sufficiently abstracted, and know where it is. Boost.MultiIndex seems like the best idea, but it's very scary and I don't wany my actual objects to need to be const.</p>
<p>What would you recommend?</p>
<p>EDIT: Boost Bimap seems nice, but does it provide stable indexing? That is, if I change the coordinate, references to other elements must remain valid. The reason I want to use pointers for indexing is because objects have otherwise no intrinsic ordering, and a pointer can remain constant while the object changes (allowing its use in a Boost MultiIndex, which, IIRC, does provide stable indexing).</p>

94,779 | <p>I am working on a client proposal and they will need to upgrade their network infrastructure to support hosting an ASP.NET application. Essentially, I need to estimate peak usage for a system with a known quantity of users (currently 250). A simple answer like "you'll need a dedicated T1 line" would probably suffice, but I'd like to have data to back it up.</p>
<p><a href="https://stackoverflow.com/questions/54184/best-tool-to-monitor-network-connection-bandwidth#54245">Another question</a> referenced NetLimiter, which looks pretty slick for getting a sense of what's being used.</p>
<p>My general thought is that I'll fire the web app up and use the system like I would anticipate it be used at the customer, really at a leisurely pace, over a certain time span, and then multiply the bandwidth usage by the number of users and divide by the time. </p>
<p>This doesn't seem very scientific. It may be good enough for a proposal, but I'd like to see if there's a better way.</p>
<p>I know there are load tools available for testing web application performance, but it seems like these would not accurately simulate peak user load for bandwidth testing purposes (too much at once).</p>
<p>The platform is Windows/ASP.NET and the application is hosted within SharePoint (MOSS 2007).</p>

94,884 | <p>The system I work on here was written before .net 2.0 and didn't have the benefit of generics. It was eventually updated to 2.0, but none of the code was refactored due to time constraints. There are a number of places where the code uses ArraysLists etc. that store things as objects. </p>
<p>From performance perspective, how important change the code to using generics? I know from a perfomance perspective, boxing and unboxing etc., it is inefficient, but how much of a performance gain will there really be from changing it? Are generics something to use on a go forward basis, or it there enough of a performance change that a conscience effort should be made to update old code?</p>

94,934 | <p>I'd like to create a "universal" debug logging function that inspects the JS namespace for well-known logging libraries.</p>
<p>For example, currently, it supports Firebug's console.log:</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-js lang-js prettyprint-override"><code> var console = window['console'];
if (console && console.log) {
console.log(message);
}</code></pre>
</div>
</div>
</p>
<p>Obviously, this only works in Firefox if Firebug is installed/enabled (it'll also work on other browsers with <a href="http://getfirebug.com/lite.html" rel="nofollow noreferrer">Firebug Lite</a>). Basically, I will be providing a JS library which I don't know what environment it will be pulled into, and I'd like to be able to figure out if there is a way to report debug output to the user.</p>
<p>So, perhaps jQuery provides something - I'd check that jQuery is present and use it. Or maybe there are well-known IE plugins that work that I can sniff for. But it has to be fairly well-established and used machinery. I can't check for every obscure log function that people create.</p>
<p>Please, only one library/technology per answer, so they can get voted ranked. Also, using alert() is a good short-term solution but breaks down if you want robust debug logging or if blocking the execution is a problem.</p>

94,975 | <p>I've read in one of my AI books that popular algorithms (A-Star, Dijkstra) for path-finding in simulation or games is also used to solve the well-known "15-puzzle".</p>
<p>Can anyone give me some pointers on how I would reduce the 15-puzzle to a graph of nodes and edges so that I could apply one of these algorithms?</p>
<p>If I were to treat each node in the graph as a game state then wouldn't that tree become quite large? Or is that just the way to do it?</p>

94,977 | <p>In C# and in Java (and possibly other languages as well), variables declared in a "try" block are not in scope in the corresponding "catch" or "finally" blocks. For example, the following code does not compile:</p>
<pre><code>try {
String s = "test";
// (more code...)
}
catch {
Console.Out.WriteLine(s); //Java fans: think "System.out.println" here instead
}
</code></pre>
<p>In this code, a compile-time error occurs on the reference to s in the catch block, because s is only in scope in the try block. (In Java, the compile error is "s cannot be resolved"; in C#, it's "The name 's' does not exist in the current context".)</p>
<p>The general solution to this issue seems to be to instead declare variables just before the try block, instead of within the try block:</p>
<pre><code>String s;
try {
s = "test";
// (more code...)
}
catch {
Console.Out.WriteLine(s); //Java fans: think "System.out.println" here instead
}
</code></pre>
<p>However, at least to me, (1) this feels like a clunky solution, and (2) it results in the variables having a larger scope than the programmer intended (the entire remainder of the method, instead of only in the context of the try-catch-finally).</p>
<p>My question is, what were/are the rationale(s) behind this language design decision (in Java, in C#, and/or in any other applicable languages)? </p>

95,007 | <p>I've been mystified by the R quantile function all day. </p>
<p>I have an intuitive notion of how quantiles work, and an M.S. in stats, but boy oh boy, the documentation for it is confusing to me. </p>
<p>From the docs:</p>
<blockquote>
<p>Q[i](p) = (1 - gamma) x[j] + gamma
x[j+1],</p>
</blockquote>
<p>I'm with it so far. For a type <em>i</em> quantile, it's an interpolation between x[j] and x [j+1], based on some mysterious constant <em>gamma</em></p>
<blockquote>
<p>where 1 <= i <= 9, (j-m)/n <= p <
(j-m+1)/ n, x[j] is the jth order
statistic, n is the sample size, and m
is a constant determined by the sample
quantile type. Here gamma depends on
the fractional part of g = np+m-j. </p>
</blockquote>
<p>So, how calculate j? m?</p>
<blockquote>
<p>For the continuous sample quantile
types (4 through 9), the sample
quantiles can be obtained by linear
interpolation between the kth order
statistic and p(k): </p>
<p>p(k) = (k - alpha) / (n - alpha - beta
+ 1),
where α and β are constants determined
by the type. Further, m = alpha + p(1
- alpha - beta), and gamma = g.</p>
</blockquote>
<p>Now I'm really lost. p, which was a constant before, is now apparently a function. </p>
<p>So for Type 7 quantiles, the default...</p>
<blockquote>
<p>Type 7</p>
<p>p(k) = (k - 1) / (n - 1). In this case, p(k) = mode[F(x[k])]. This is used by S. </p>
</blockquote>
<p>Anyone want to help me out? In particular I'm confused by the notation of p being a function and a constant, what the heck <em>m</em> is, and now to calculate j for some particular <em>p</em>. </p>
<p>I hope that based on the answers here, we can submit some revised documentation that better explains what is going on here. </p>

95,077 | <p>What is the best way to store string data across postback. I need to store an ID and name for multiple entities. I was thinking of using a datatable in viewstate, but would that make viewstate grow too large? I can't use a database yet because I'll be inserting a record that those other records need to be related to. So I'll just be storing them temporarily until the user submits the form.</p>

<p>I got this error:</p>
<blockquote>
<p>SQL error near line 84802: no such column: Ð</p>

<p>In that line the script is this:</p>
<blockquote>

<p>My guess is that <strong>the 'Ñ' without quotes is the problem</strong>.</p>
<p>any idea?</p>

95,106 | <p>Is there a Vim shortcut for jumping to the argument list of the current function? I often find myself needing to mess with the argument list of a function, and it's kind of annoying to have to do ?def or ?function or 10k or what-have-you until I finally get to it, then /( or t( or 5e to get to the right position in the argument list, and so on. It would be great if I could just hit ,a for example and instantly get put into insert mode at the end/beginning of the argument list.</p>
<p>Possible approaches:</p>
<ul>
<li>Folding</li>
<li>Tag support (ctags)</li>
</ul>
<p>Also, I'm using Python, so solutions based on curly braces unfortunately won't work.</p>
<p>If no such shortcut exists, I'll just write one and post it here as an answer. :-)</p>

<p>Does the tag access the ResultSet directly, or is the query result being stored in a datastructure in memory?</p>
<p>When is the connection closed?</p>

<p>Note: I've always been against running queries in the jsp, but my result set is too large to store in memory between my action and my jsp. Using this tag library looks like the easiest solution.</p>

Insert Error: Column name or number of supplied values does not match table definition.

<p>The most curious thing about this is that each of the individual statements in the trigger works on its own. It's almost as though inserted is a one-off table that infects temporary tables if you try to move inserted into one of them.</p>
<p>So what causes the trigger to fail? How can it be stopped?</p>

95,222 | <p>I found this link <a href="http://artis.imag.fr/~Xavier.Decoret/resources/glsl-mode/" rel="noreferrer">http://artis.imag.fr/~Xavier.Decoret/resources/glsl-mode/</a>, but there isn't a lot of description around it, aside that it's "simple".</p>
<p>Ideally, I'd like an extension to CcMode that can do it, or at least a mode that can handle auto-styling and has similar shortcuts to CcMode.</p>
<p>If there isn't one, any good elisp references to help me get started writing it myself would be greatly appreciated.</p>
<p>EDIT: David's response prompted me to take a closer look at glsl-mode.el, and it is in fact based on cc-mode, so it's exactly what I was looking for in the first place.</p>

95,361 | <p>I'm programming in C++ on Visual Studio 2005. My question deals with .rc files. You can manually place include directives like (#include "blah.h"), at the top of an .rc file. But that's bad news since the first time someone opens the .rc file in the resource editor, it gets overwritten. I know there is a place to make these defines so that they don't get trashed but I can't find it and googling hasn't helped. Anyone know?</p>

95,378 | <p>What is a tool or technique that can be used to perform spell checks upon a whole source code base and its associated resource files?</p>
<p>The spell check should be <em>source code aware</em> meaning that it would stick to checking string literals in the code and not the code itself. Bonus points if the spell checker understands common resource file formats, for example text files containing name-value pairs (only check the values). Super-bonus points if you can tell it which parts of an XML DTD or Schema should be checked and which should be ignored.</p>
<p>Many IDEs can do this for the file you are currently working with. The difference in what I am looking for is something that can operate upon a whole source code base at once.</p>
<p>Something like a Findbugs or PMD type tool for mis-spellings would be ideal.</p>

<p>I'm assuming that if I know the command-line statement for bringing up this prompt, it will allow me to pass in a parameter for what folder I want to be searching under.

<li>I have an Oracle database backup file (.dmp) that was created with <code>expdp</code>.</li>
<li>The .dmp file was an export of an entire database.</li>
<li>I need to restore 1 of the schemas from within this dump file.</li>
<li>I don't know the names of the schemas inside this dump file.</li>
<li>To use <code>impdp</code> to import the data I need the name of the schema to load.</li>
</ul>
<p>So, I need to inspect the .dmp file and list all of the schemas in it, how do I do that?</p>
<hr />
<p><em>Update (2008-09-18 13:02) - More detailed information:</em></p>
<p>The impdp command i'm current using is:</p>
<pre><code>impdp user/password@database directory=DPUMP_DIR
dumpfile=EXPORT.DMP logfile=IMPORT.LOG
</code></pre>
<p>And the DPUMP_DIR is correctly configured.</p>
<pre><code>SQL> SELECT directory_path
2 FROM dba_directories
3 WHERE directory_name = 'DPUMP_DIR';
DIRECTORY_PATH
-------------------------
D:\directory_path\dpump_dir\
</code></pre>
<p>And yes, the EXPORT.DMP file is in fact in that folder.</p>
<p>The error message I get when I run the <code>impdp</code> command is:</p>
<pre><code>Connected to: Oracle Database 10g Enterprise Edition ...
ORA-31655: no data or metadata objects selected for the job
ORA-39154: Objects from foreign schemas have been removed from import
</code></pre>
<p>This error message is mostly expected. I need the <code>impdp</code> command be:</p>
<pre><code>impdp user/password@database directory=DPUMP_DIR dumpfile=EXPORT.DMP
SCHEMAS=SOURCE_SCHEMA REMAP_SCHEMA=SOURCE_SCHEMA:MY_SCHEMA
</code></pre>
<p>But to do that, I need the source schema.</p>

95,600 | <p>The documentation indicates that the error: option function will make available: XHR instance, a status message string (in this case always error) and an optional exception object returned from the XHR instance (Book: JQuery in Action)</p>
<p>Using the following (in the $.ajax call) I was able to determine I had a "parsererror" and a "timeout" (since I added the timeout: option) error</p>
<pre><code>error: function(request, error){}
</code></pre>
<p>What are other things you evaluate in the error option? do you include the optional exception object?</p>
<p><strong>EDIT:</strong> one of the answers indicates all the return errors...learning more about what is of value (for debugging) in the XHR instance and exception object would be helpful</p>
<p>This is a complete $.ajax call:</p>
<pre><code>$.ajax({
type: "post",
url: "http://myServer/cgi-bin/broker" ,
dataType: "text",
data: {
'_service' : 'myService',
'_program' : 'myProgram',
'start' : start,
'end' : end
},
beforeSend: function() {
$("#loading").removeClass("hide");
},
timeout: 5000,
error: function(request,error) {
$("#loading").addClass("hide");
if (error == "timeout") {
$("#error").append("The request timed out, please resubmit");
}
else {
$("#error").append("ERROR: " + error);
}
},
success: function(request) {
$("#loading").addClass("hide");
var t = eval( "(" + request + ")" ) ;
} // End success
}); // End ajax method
</code></pre>

95,642 | <p>Long story short, I have a substantial Python application that, among other things, does outcalls to "losetup", "mount", etc. on Linux. Essentially consuming system resources that must be released when complete.</p>
<p>If my application crashes, I want to ensure these system resources are properly released.</p>
<p>Does it make sense to do something like the following?</p>
<pre><code>def main():
# TODO: main application entry point
pass
def cleanup():
# TODO: release system resources here
pass
if __name__ == "__main__":
try:
main()
except:
cleanup()
raise
</code></pre>
<p>Is this something that is typically done? Is there a better way? Perhaps the destructor in a singleton class?</p>

95,683 | <p>I have a .NET 3.5 (target framework) web application. I have some code that looks like this:</p>
<pre><code>public string LogPath { get; private set; }
public string ErrorMsg { get; private set; }
</code></pre>
<p>It's giving me this compilation error for these lines:</p>
<pre><code>"must declare a body because it is not marked abstract or extern."
</code></pre>
<p>Any ideas? My understanding was that this style of property was valid as of .NET 3.0.</p>
<p>Thanks!</p>
<hr>
<p>The problem turned out to be in my .sln file itself. Although I was changing the target version in my build options, in the .sln file, I found this:</p>
<pre><code>TargetFramework = "3.0"
</code></pre>
<p>Changing that to "3.5" solved it. Thanks, guys!</p>

<pre><code>var execBtn = document.createElement('input');
execBtn.setAttribute("type", "button");
execBtn.setAttribute("id", "execBtn");
execBtn.setAttribute("value", "Execute");
execBtn.setAttribute("onclick", "runCommand();");
</code></pre>
<p>Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run.</p>
<pre><code>execBtn.onclick = function() { runCommand() };
</code></pre>
<p><strong>BAD IDEAS:</strong></p>
<p>You can do </p>
<pre><code>execBtn.setAttribute("onclick", function() { runCommand() });
</code></pre>
<p>but it will break in IE in non-standards mode according to @scunliffe.</p>
<p>You can't do this at all </p>
<pre><code>execBtn.setAttribute("onclick", runCommand() );
</code></pre>
<p>because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do</p>
<pre><code>execBtn.setAttribute("onclick", runCommand);
</code></pre>

95,820 | <p>Let's say I have an array, and I know I'm going to be doing a lot of "Does the array contain X?" checks. The efficient way to do this is to turn that array into a hash, where the keys are the array's elements, and then you can just say <pre>if($hash{X}) { ... }</pre></p>
<p>Is there an easy way to do this array-to-hash conversion? Ideally, it should be versatile enough to take an anonymous array and return an anonymous hash.</p>

95,821 | <p>I have been playing with Haml recently and really like the way the resulting code looks to me...the developer. I'm also not too worried about a designer being able to consume or change it...we're a small team. </p>
<p>That said, beginning work on a project we believe will generate quite a bit of traffic (who doesn't?). I'm concerned that there are things I just don't know about haml. Is there anything erb can do that haml can't? Does haml have a negative effect as a project grows? Are there other things that should be considered?</p>
<p>And finally...how does Haml compare speedwise to erubis? I see that it supposedly beats erb and eruby now...</p>
<p>Thanks!</p>

95,824 | <p>I'm looking for a way to do a substring replace on a string in LaTeX. What I'd like to do is build a command that I can call like this:</p>
<pre><code>\replace{File,New}
</code></pre>
<p>and that would generate something like</p>
<pre><code>\textbf{File}$\rightarrow$\textbf{New}
</code></pre>
<p>This is a simple example, but I'd like to be able to put formatting/structure in a single command rather than everywhere in the document. I know that I could build several commands that take increasing numbers of parameters, but I'm hoping that there is an easier way. </p>
<p><strong>Edit for clarification</strong></p>
<p>I'm looking for an equivalent of </p>
<pre><code>string.replace(",", "$\rightarrow$)
</code></pre>
<p>something that can take an arbitrary string, and replace a substring with another substring.</p>
<p>So I could call the command with \replace{File}, \replace{File,New}, \replace{File,Options,User}, etc., wrap the words with bold formatting, and replace any commas with the right arrow command. Even if the "wrapping with bold" bit is too difficult (as I think it might be), just the replace part would be helpful.</p>

95,834 | <p>I have a Windows Workflow application that uses classes I've written for COM automation. I'm opening Word and Excel from my classes using COM.</p>
<p>I'm currently implementing IDisposable in my COM helper and using Marshal.ReleaseComObject(). However, if my Workflow fails, the Dispose() method isn't being called and the Word or Excel handles stay open and my application hangs.</p>
<p>The solution to this problem is pretty straightforward, but rather than just solve it, I'd like to learn something and gain insight into the right way to work with COM. I'm looking for the "best" or most efficient and safest way to handle the lifecycle of the classes that own the COM handles. Patterns, best practices, or sample code would be helpful.</p>

95,842 | <p>The name of a temporary table such as #t1 can be determined using </p>
<pre><code>select @TableName = [Name]

<p>How can I find the name of a table valued variable, i.e. one declared by</p>

<p>the purpose is to be able to get meta-information about the table, using something like</p>
<pre><code>select @Headers = dbo.Concatenate('[' + c.[Name] + ']')
from sys.all_columns c
inner join sys.tables t
on c.object_id = t.object_id
where t.name = @TableName

<p>although for temp tables you have to look in <code>tempdb.sys.tables</code> instead of <code>sys.tables</code>. where do you look for table valued variables?</p>
<hr>
<p>I realize now that I can't do what I wanted to do, which is write a generic function for formatting table valued variables into html tables. For starters, in sql server 2005 you can't pass table valued parameters:</p>
<p><a href="http://www.sqlteam.com/article/sql-server-2008-table-valued-parameters" rel="nofollow noreferrer">http://www.sqlteam.com/article/sql-server-2008-table-valued-parameters</a></p>
<p>moreover, in sql server 2008, the parameters have to be strongly typed, so you will always know the number and type of columns.</p>

95,858 | <p>I have a web application that is dynamically loading PDF files for viewing in the browser.
Currently, it uses "innerHTML" to replace a div with the PDF Object. This works.</p>
<p>But, is there a better way to get the ID of the element and set the "src" or "data" parameter for the Object / Embed and have it instantly load up a new document?
I'm hoping the instance of Adobe Acrobat Reader will stay on the screen, but the new document will load into it.</p>
<p>Here is a JavaScript example of the object:</p>
<pre><code>document.getElementById(`divPDF`).innerHTML = `<OBJECT id='objPDF' DATA="'+strFilename+'" TYPE="application/pdf" TITLE="IMAGING" WIDTH="100%" HEIGHT="100%"></object>`;
