I am writing a 32bit windows MFC application for NT4

I have a Third party Win3.1 16bit DLL with functions that I need to call.

Is this a valid scenario ?
If so how do I set about it ?

I have the prototypes for the functions in the dll.

Unfortunately you can't do this under NT4 - only under Win95/98
In WinNT4 only 16-bit code can call 32 bit DLL.
If you want 32 bit code to call 16 bit code trhen you can use DDE, RPC, OLE, Named Pipes, WM_COPYDATA or whatever indirect methof you want. But you can't mix 16 bit DLLs and 32 bit program in one process
