I encountered a similar problem. I wanted to compile link a DLL from VC6 with
LabWindows/CVI. I found that you have to have the DLLs in the Microsoft VC5
and earlier for them to work with LabWinCVI.
To switch VC6 linker to the 5.0 compatibility mode, use the linker command
line switch:
/LINK50COMPAT
This can be added to the linker option of the project.
