I am trying to call a dll function from Visual Basic and am getting
a "Undefined function" message. The DLL is being generated using
Borland BCC compiler with -WD option. VB finds the DLL, it just can't
find the functions in the DLL. Does anyone know what's wrong?

=====================dll.cpp follows=======================

#include <windows.h>
#include <dos.h>
 
int FAR PASCAL LibMain
	(HANDLE hInstance	// DLL instance handle
	,WORD wDataSeg		// DS register value
	,WORD cbHeapSize	// size of local heap
	,LPSTR lpCmdLine	// far pointer to command line loading DLL
	)
{
	return 1;
}
 
unsigned char Myin(int portid)
{
	return inportb(portid);
}
 
unsigned int Myinw(int portid)
{
	return inport(portid);
}
 
int FAR PASCAL WEP(int nParameter)
{
	return 1;
}

I voted for Bush once.  As it's turning out, once was once too often.
