This code produces a messagebox containing an OpenGL error inside a message box

I use this for debugging purposes only, not for my main error detection from within my programs. It's very easy to 'drop' into code, but it creates a horrible mess for a user.

(requires < window.h >)

GLenum errorCode;

  if(errorCode = glGetError()!= GL_NO_ERROR)
	{
		::MessageBox(NULL, (char *)gluErrorString(errorCode),
		  "OpenGL Error",MB_ICONERROR | MB_OK);
	}
