... | <p>Since you're using dynamic arrays, <code>array of</code>, then you should use SetLength to specify the length of the array, which can be done dynamically.</p>
<p>ie. like this:</p>
<pre><code>SetLength(Data, 100);
</code></pre>
<p>This will not reserve 100 bytes, but will reserve enough space to hold 100 elements... | <p>Also note that In Delphi variables of a dynamic array type are stored as a pointer (in DotNet-speak you would call this a reference-type).</p>
<p>Unless you cast this variable to a pointer, the compiler won't let you do the allocation yourself. You should use SetLength() like lassevk mentioned already.</p>

<p>Is there any sort of free control which does what the Occupation field does on <a href="http://monster.ca" rel="nofollow noreferrer">http://monster.ca</a>?

I just learned about the <a href="http://www.braintrove.com/article/18" ... | <p>It is just a mock up of a drop down control.<br>
The down arrow is an image, all the remainder is made of divs, the drop down list itself being a big div with overflow containing lot of controls with JavaScript to manage all of this (like collapsing sections).</p>

<p>I'm developing an idea for a web application that would be well suited to one of the popular MVC frameworks out there right now, but torn between which to go with.

<p>We have found that as far as maintainability as quickest turn around time to complete our projects are concerned, Ruby on Rails (or MERB) offers the best solutions. I'm a .Net guy too, but the other guys here seem to think that it's much easier wr... | <p>A colleague of mine has been working with Django for quite a while now, and did an exploration of ASP.NET MVC recently. His conclusion was that ASP.NET MVC wasn't quite ready for prime time as compared with Django as of about a month ago (preview 4 release).</p>

<p>What is a good site to check current web usage statistics -- particularly Java version, OS, browser. I have been trying to figure out Google Zeitgeist because it supposedly has this information, but I can't find it.</p>

<p>I want to develop a windows application. If I use native C++ and MFC for user interface then the application will be very fast and tiny. But using MFC is very complicated. Also If I use C# then the application will be slower than the native code and It reqiures .NET framework to run. But developing GUI is very easy ... | <p>"fast" and "slow" are subjective, especially with today's PC's. I'm not saying deliberately make the thing slow, but there isn't <em>nearly</em> as much overhead in writing a managed application as you might think. The JIT etc work very well to make the code execute very fast. And you can also NGEN for extra start-u... | <p>Choice of a language or tool should be dictated by the functional and performance requirements of your project and expertise. If performance is a real consideration for you and you have done some analysis to prefer C++ over C#, then you have a decision already.

<p>Is there a way to search Microsoft Visual SourceSafe 6.0d for all files tagged with a specific label?</p>
| <p>AJ had the right idea, but you just need to use the "dir" command instead of get:</p>
<pre><code>ss dir -v"LABEL" $\PROJECT -R
</code></pre>
<p>This will output each file with version that is at that label in the format of:</p>
<pre><code>someFile.c;23
someOtherFile.h;3
<filename>;<version>
</code></p... | <p>You can get by label.<br>
This may not be the same as searching by label. </p>
<p>Sourcesafe accepts a label as a valid version number, so it's the same syntax: </p>
<pre><code>ss get -V"my label" $\myproject -R
</code></pre>
<p>this will get everything labelled <code>my label</code> from the <code>myproject</c... | 32,861 |
<p>I'm looking for a straightforward example / tutorial for implementing a JAX-WS (soap1.1 and soap1.2) web service based on wsdl definition using spring, axis2 and tomcat.</p>
<p>hint anyone ?</p>
<p>-- Yonatan </p>
| <p>There is no such thing as "straightforward" in the world of SOAP. Any example and tutorial is bound to be complex due to the overengineered nature of this beast.</p>
<p>If you can choose your technologies, I'd recommend putting axis aside, and using Tomcat 6 + Java 6 + Metro. <a href="https://metro.dev.java.net/" r... | <p>The NetBeans IDE is good place to start. Enable the Axis2 Support in NB plug-ins. You can create a JAX-WS based Web Service from the WSDL (assuming you are using contract first) and the JAX-WS based WS client too. If you dont like what NetBeans generates or its deployment strategy, you can still build upon the code ... | 26,647 |
