The RoBoIO lib for VC2005 has been compiled with STDCALL standard so that ones are able to call RoBoIO lib in VB6 or VB.NET. You can find many tutorials on internet that explain how to call C++ lib with following STDCALL in VB:)

Visual basic with the C++ DLLs

I haven't heard about that.

However it should be possible since they are C style DLLs. (provided you write the function definitions yourself)

If you're running VB6 or earlier the only thing is that the DLL needs to be compiled with STDCALL standard and not the CDECL standard.
Info and workarounds for that are available here http://support.microsoft.com/kb/153586

For VB.Net I am not sure but I believe it should also be possible and most likely this limitation of calling conventions does not apply.

Has anyone been able to use Visual Basic with the C++ DLL to control anything?
