I wouldn't do it if I were you, because if your dataset is large, then you are increasing the number of rows without any real need and also you are running a risk of an inconsistency (your layout heavily de... | 41,387 |
<p>I'm getting near completely different objects from the same WSDL file when I try to Add a Web Reference depending if I am using Express or Pro version of the vs2008 .NET IDE.</p>
<p>1) Why is this happening? I'd expect the WSDL's to act the same across platforms--clearly they are not!

<p>The real solution for this right now is to write your own contracts and proxies. I know, it's not great news, but 30 minutes of typing might save you from a world of hurt.</p>

| <p><strong>Declaration</strong></p>
<p>A prototype for a function which takes a function parameter looks like the following:</p>
<pre><code>void func ( void (*f)(int) );
</code></pre>
<p>This states that the parameter <code>f</code> will be a pointer to a function which has a <code>void</code> return type and which ... | <p>It's not really a function, but it is an localised piece of code. Of course it doesn't pass the code just the result. It won't work if passed to an event dispatcher to be run at a later time (as the result is calculated now and not when the event occurs). But it does localise your code into one place if that is all... | 3,083 |
<p>How do I create a toolbar for Excel using an XLA document?</p>
| <p>To make a toolbar, in the onload event, you are going to do something like:</p>
