Having a frustrating time trying to call a function in a DLL developed in
VC++ 4.0 from Visual Basic 4.0 (32bit). I'm getting VB error 49 (bad DLL
calling convention) from the following simple function ...

In mydll.h
#define DllExport __declspec(dllexport)
extern "C" long DllExport TestLongParam(long lParam);

In mydll.cpp
extern "C" long DllExport TestLongParam(long lParam)
{
	TRACE("TestLongParam called with %ld\n", lParam);
	return(1L);
}

The Declare in VB is
Declare Function TestLongParam Lib "MYDLL.DLL" (ByVal lParam As Long) As Long

When I call TestLongParam from VB, I get the TRACE output with the correct 
value for the passed parameter, but on return, VB gives error 49.

Can anyone sugesst what is wrong with the way I have declared the functions ?
I have played around with the __stdcall modifier, the WINAPI macro and even
tried the old obsolete FAR PASCAL with no success.

Thx
