PlaySound() with resources

Well, I can play sound from .wav files..., but it doesn't work with resources.

Code:

//sound.cpp
#include <iostream> 
#include <windows.h>
#include "res.h"
#include "data.rc"
#pragma comment(lib,"winmm")
int main() 
{ 
  PlaySound(MAKEINTRESOURCE(ID_SOUND),NULL, SND_ASYNC | SND_RESOURCE); 

}

//data.rc

#include "res.h"
ID_SOUND WAVE DISCARDABLE  "data.wav"

//res.h

#define ID_SOUND 333

It gives me the following error:

Error 1 error C2059: syntax error : 'constant' c:\documents and settings\olafs.ntworld-9ba1e5e\desktop\misc\programming\visual c++ projects\general\data.rc 2

Whats wrong with my resource? Every tutorial says exactly the same to put in there

Code:

ID_SOUND WAVE DISCARDABLE  "data.wav"

DO NOT INCLUDE RESOURCE FILES.
Just add resource files to your project, do not #include them.

Ah, thanks, now it says:
Error 1 fatal error RC1004: unexpected end of file found c:\Documents and Settings\Olafs.NTWORLD-9BA1E5E\Desktop\Misc\Programming\Visual C++ Projects\general\res.h 1

EDIT: It's all working now! Just added a empty line at the end of the header file.
Thanks maxorator.
