| <p>First off, in Actionscript you don't need to explicitly mark a method to be overridden as virtual as you do in C#, the compiler will do this for you. This is why the keyword doesn't show up in any docs because it is irrelevant from the developers perspective.</p>

<p>I have a xml blob that's checked against a schema in sql 2005. My website uses xsl to transform and display the blob. How do I add a hyperlink to the xml (in any node) without the sql 2005 schema complaining a node was found in the wrong place? Or the xsl thinking that the hyperlink is a valid xml node?</p>

This way, live data isn't tainted, and your code looks identical.

For example, point of sale systems in a supermarket: cashiers are trained on the production point of sale terminals.</p>
<p>The key is to carefully identify the test or training data. I wouldn't say that there's any explicit best practice for how to model this i... | 20,150 |
<p>What avenues are there for using an XSD to generate message instances? I seem to remember reading about generating classes from XSD, but can't find anything specific now. I know you can generate classes and datasets from XSD, but I'm looking for a pattern for automating the actual generation of the messages.</p>
... | <pre><code>xsd /c yourschema.xsd > yourschema.cs
</code></pre>
| <p>You can also create an XSD from XML samples with xsd.exe. Start the visual studio command prompt and use it to create an xsd from an xml sample. Then you can, as leppie shows, use xsd.exe to create a typed data set from that XSD. I wouldn't recommend doing this blindly, but it can certainly help when using a thir... | 22,598 |
<p>I know the Html.Button has been moved to the Microsoft.Web.Mvc namespace, but I really miss the generic versions that used to exist in the early Previews. </p>
<p>All I want the Html.Button to do is to hit an action in my controller, but I'd rather not write the JavaScript in the onClickMethod argument.</p>
<p>In ... | <p>The problem with the generic versions is that filters are allowed to change the actual name of the action away from the name of the method (like the [ActionName] attribute).</p>
| <p>Yes, they really screwed up with Html.Button and Html.CheckBox in CTP5. I hope they return to the previous behaviour.</p>
