Greetings!

I tried to play an mp3 using MCI function, play(). But Visual C++ 6.0 doesn’t recognize the function. Below is what I have written.
Code:
#define _WIN32_WINNT 0x0501 
#define WINVER 0x0501
#include "stdafx.h"

DWORD Play(LPSTR lpstrAlias) 
{ 
    char    achCommandBuff[128]; 
    wsprintf(achCommandBuff, "play ", lpstrAlias); 
    return mciSendString(achCommandBuff, NULL, 0, NULL); 
} 

int main(int argc, char* argv[])
{	
	Play("C:\\Program Files\\Britannica\\2002\\multimedia\\mp3\\oharp00004u2.mp3");
	return 0;
}
What are the means of fixing this problem?
Thanks.
