Actually, I did forget while typing that message - but it doesn't affect my response. <g>

Let me explain in some more detail. There are two types of functions here - intrinsics and externals. CInt and CStr are intrinsics - so they cannot be called by C# or any other language. Other functions like UCase are external, and can be called by other languages. To make things a little more confusing, some of our intrinsics, in some cases, may call helper functions that are in the microsoft.visualbasic namespace - and C# developers could find them and call them - though I don't think they are documented (though intellisense should still work).

I get the feeling that I just made things clear as mud. <g>
