This is not really the group to ask this question - as it doesn't have anything to do with python.NET.
But other then that I can answer your question I think :-)
You say a "C++ DLL". First thing is you need to make sure that your functions are correctly exported in an 'unmangled' form.
What I do for this is the following:
// create a macro DLLEXPORT for those methods you want to export
#define DLLEXPORT extern "C" __declspec(dllexport)
// the following may be optional - but can make things easier
#define VB __stdcall
// add the macro to your function prototypes
DLLEXPORT int VB InitDialogFromFile (char const *const fileName);
// in the CPP file define your function as you would normally do
int VB InitDialogFromFile(char const * const fileName)
You may also need to create a .def file
; Declares the module parameters for the DLL.
DESCRIPTION 'Description of your DLL'
// the following line can be used to rename exports
//InitDialogFromFile_renamed = InitDialogFromFile
Once you add that to the project - it will make sure that no mangling happens (sometimes even after doing extern "C" you still get a leading underscore!)
