visual studio - OpenGL ES Tutorial - 'Winmain': function cannot be overloaded

Question

I'm trying to learn OpenGL ES with the "OpenGL ES Training Course" (An OpenGL ES tutorial). I use OPENGL-ES 1.1 WINDOWS PC EMULATION with visual studio 2010. I'm trying to compile the 'hello triangle' program and get an error:

'WinMain': function cannot be overloaded

EDIT: I have only one definition of WinMain in the project: The one in the 'hello triangle' source code (which I didn't write).

Could anyone tell me what's going on?

Answer 1

It sounds like you have two definitions of WinMain, or perhaps a prototype and a definition that disagree.
