    Linker Error

    Hi,
    I have a VC 6 project with a few C source code files,and one c++ source
    file. When I refer to any function in the c++ file from the C file, i get a
    Linker error saying that "error LNK2001: unresolved external symbol
    _AddPicture" ( AddPicture) is the name of the function that i am referring
    to. Function Protoypes and header files have been defined correctly.

    Thanks and Regards
