You shouldn't need any - it's an API call

>Where does the code go
Where you want a beep <g>

Seriously, just to clarify: you say the VB example works and the C# does not ? What happens with the C# version?

What platform are you targeting - maybe not all support the MessageBeep() API call?

If all else fails you could, of course, import the VisualBasic dll:

using Microsoft.VisualBasic;
MessageBeep(x);

It might give you better cross-platform support but the DLL size may be a factor....
