Thank you. It now compiles. And it works perfectly on my machine. However it still generates an error whenever I show it to somebody else:

this application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

My code:

#include <Windows.h>
#include <tchar.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
				   LPSTR lpCmdLine, int nShowCmd)
{
	MessageBox(NULL, _T("Hello!"), 
		_T("Hello World"), MB_OK | MB_ICONINFORMATION);
	if (MessageBox(NULL, _T("I'm learning to use C++ to write native Windows programs.  Cool, isn't it?"),
		_T("Cool, No?"), MB_YESNO | MB_ICONQUESTION) == IDYES)
		MessageBox(NULL, _T("You know it!"), _T("Sweet!"), MB_OK);
	else MessageBox(NULL, _T("Jerk."), _T("Grrr"), MB_OK);
	return 0;
}
