Hi !

Could you please post the exact error message you get (it includes an error code, like C1234 for example) and a line number, and is it a compilation error (I guess it is) or a linking error ?

A wild guess (because you did not provide much info to work with), you are trying to compile this code as a "console" project and not as a "Win32 Application" project.

Use MessageBox instead of messageBox. And then pick up a book on C/C++ and find out why those are different.
