Creating DLL's in Visual C++, for use in VB
I am creating some DLL's in Microsoft's Visual C++ for use in VB.
I can compile and create the DLL's, however, when I try to register them using regsvr32.exe or try to access them in VB using the DECLARE method, the system can't find a DLL entry point.
Do I need to explicitly create this in the VC++ code, or is there a setting I need to use - which I do not know about,

You should note that VB uses _stdcall calling convention for functions in DLLs
Is this a Standard DLL or a DLL that exports some com compliant interface ??

Have U defined UR exported functions in .def file in the dll? if not so add them and try

I believe, if I'm not mistaken, that you may also need to make sure that your references in VB are updated to include the dll so that VB knows what kind of objects you are using...
You don't need a DEF file to export functions
You do need the def file to set theexported names correctly for VB to find them
There is an alternative for def file:
extern "C"
extern "C"

Remember to declare the functions in the DLL as EXPORT.
