PlaySound Question
in [MFC]

From: Jack on 26 Jun 2010 09:23 Hi, I want to play a wave file when I click on a button #include <MMSystem.h> .... int CDialog::OnBtnClick(...) { PlaySound("123.wav", NULL, SND_FILENAME); } But PlaySound and SND_FILENAME identifiers are not found. Any ideas? Thanks Jack

Any ideas? > Thanks > Jack The documentation for PlaySound says: Header: Declared in Mmsystem.h; include Windows.h That means you are supposed to include Windows.h, not mmsystem.h Also note that the next line of the documentation says you must link to Winmm.lib. Add that filename in 'Additional Dependencies' in the linker section of the project properties. -- Scott McPhillips [VC++ MVP]
From: Joseph M. Newcomer on 26 Jun 2010 16:00 Where did the #include <mmSystem.h> appear? Before or after the #include "stdafx.h"? If before, then this is treated as an ill-formed comment and has no effect! Sadly, you only gave the #include as if it is the ONLY #include in your application, which I doubt. Context matters. joe ..

Any ideas? To add to what Scott and Joe already pointed out, you may want to use _T("...") decorator for "123.wav" string literal, or else you may have some other error in Unicode builds (after you fix the #incldude thing).
