Compiling a CIN with VC++ 6.0, I'm trying to use extension .cpp instead of ..c. It's interesting .c file works but .cpp doesn't work with the same project settings except the different extension.
CIN's don't support C++ code, just C code. The cpp extension is for C++ files. When you are compiling, in most compilers, naming the code file .cpp tells the compiler to use the C++ compiler and .c tells the compiler to use the C compiler. Your error is resulting because you are using the C++ compiler.
You can use *.cpp files and LabView supports C++ as well. Rename the generated *.c file into *.cpp and include this file in your VC++ project. Declare your function in a Header-file (*.h) separately and describe the interface as extern "C"
#ifdef __cplusplus extern "C" { #endif
CIN MgErr CINRun(int32 *hWnd);
#ifdef __cplusplus } #endif

Hi, I'm encountering the same method and I tried the above method but it doesn't seem to work. Could someone explain the part about .cpp vs. .c files again? Also, Chemo, did you manage to find a solution to your problem? Thanks!
