Opening movie file with a program within a program?

[nicedude80]

What I mean is, is it possible to open a .wav or whatever with the users default video player. Like this:

OpenFile(movie.wav, defaultProgram);

DefaultProgram probably being some winApi code. This program would be used on windows, so I am not worried about cross platform.

I have found out about ShellExecute, but it gives me this error:

#define ShellExecute ShellExecuteA
Error: Identifier "ShellExecuteA" is undefined

This is the code I am trying to call, with #include <shellAPI>:

ShellExecute(NULL, L"open", pathToVideo, NULL, NULL, SW_SHOW);
