You could add somthing like in the aspx even if its not a great solution:

IDOfYourControl.myintarray = new Int32[] { 1, 2, 3 };

}

The GLUT port on Nate Robin's site is from 2001 and has some incompatibilities with versions of Visual Studio more recent than that (.NET 2003 and up). The incompatibility manifests itself as errors about redefinition of `exit()`. If you see this error, there are two possible solutions:

Keyboard accelerators. Once you figure out what sorts of queries you write a lot, write utility stored procedures to automate the tasks, and map them to keyboard shortcuts.

The knuth shuffle is an insignificant change compared to the naive shuffle: Just swap with any card in the remaining (unshuffled) section of the deck instead of anywhere in the entire deck.

Yes, and no, it's not very useful in my opinion. It's not very stable, it's easy to get out of sync, and the "look how fast I generate this" advantage is virtually nil when compared to more mundane things such as code snippets.

> When I check the download page for Report Viewer 2008, it lists .NET 3.5 as a requirement.

MSFT may have placed some sort of restriction on the Report Viewer requiring .Net 3.5. In your testing, make sure you can successfully install on a machine with both no Framework at all, and only the 2.0 Framework.

I don't see any reason to believe that creating an object in the constructor will automatically dispose the object. Yes, your object will immediately go out of scope and be available for garbage collection, but that is certainly not the same as being disposed.
