Creating 16bit DLL with MSVC 1.5 using CVI functions

[jtelles]

I have created c files under CVI using some functions from "userint.h". When attempting to create a DLL in MSVC 1.5, I recieve the L20209 error. I've checked to ensure that userint.h and all necessary headers are included. I've also sucessfully created a .LIB from MSVC and incorporated it into the project before building the DLL. The L2029 error indicates a unresolved external error for the GenericMessagePopup function from CVI. I've also set the MSVC complier, linker and resource options according to the NI tutorial.

Hello,

Unfortunately I do not have any information about MSVC 1.5, or access to that particular version of the software. I suspect the issue may be that the CVI DLLs are Win32 and that version of the compiler is 16-bit only. The question is really if that version of the MSVC environment is capable of calling these particular DLLs. You may be able to find some information on this through Microsoft.
