When I did this I found that
- All the exported functions needed to be "stdcall".
- VB must refer to the DLL functions using the exact same case (very
un-VB!) otherwise it won't find them.
Here is what the VB code looked like (vb stands for something else, not
visual basic, in the context of our application)
'vbdriver.dll must be in search path -- best to place in %WinSys%
Declare Function vbGetDllVersion Lib "vbdriver.dll" () As Integer
And the DLL declaration of vbGetDllVersion was:
function vbGetDllVersion : integer; stdcall;
(and it was exported of course)
Hope that helps
Mike
