Have you linked to the multimedia library, Winmm.lib, as Scott said? This library is not linked by default, you have to do it explicitly.

Just edit "stdafx.h" and add in it: #include "Mmsystem.h" Then rebuild; it should compile. If it does not link, add Winmm.lib using the IDE as suggested above by Scott (or use #pragma comment(lib, "Winmm.lib") in some source file). Giovanni

The framework insists on putting them in, just in case you ran this under Windows 4.0 (too bad the framework has not caught up with modern operating systems) **** > >// The system calls this function to obtain the cursor to display while >the user drags >// the minimized window. >HCURSOR CMFCSimple01Dlg::OnQueryDragIcon() >{ > return static_cast<HCURSOR>(m_hIcon); >} **** ditto **** > > >void CMFCSimple01Dlg::OnBnClickedSayhi() >{ > GetDlgItem(IDC_HI)->SetWindowText("Hi!"); > > > > > CUGCell cell; > cell.SetText("Hello"); > m_Grid.SetCell(0,0,&cell); > InvalidateRect(NULL, FALSE); > PlaySound("123.wav", NULL, SND_FILENAME); **** As pointed out, this should be _T("123.wav"), and you would be better off making it a resource. Check to see that the symbols are included; there might be an #ifdef or #ifndef in mmsystem.h, or where mmsystem.h is included. You would need to either define that symbol, make sure it has the right value (it might be for some antique OS), or make sure the symbol is *not* defined.
