void CDemoDlg::GetDirList(CString sPath)
{
	WIN32_FIND_DATA FindFileData;
	sTmpPath = sPath;
	sTmpPath += "\\*.*";
	HANDLE hFind = FindFirstFile( sTmpPath, &FindFileData );
	if ( hFind == INVALID_HANDLE_VALUE )
        return;
    else {
		do {
		if ( ( FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ) )
		 {
		// if directory:
		if ( strcmp(".", FindFileData.cFileName ) && strcmp("..", FindFileData.cFileName) ) 
		{
		sTmpPath = sPath;
		sTmpPath += "\\";
		sTmpPath += FindFileData.cFileName;
		GetDirList( sTmpPath);
		}
	} 
	else // if file:
	{
	sTmpPath = sPath;
	sTmpPath += "\\";
	sTmpPath += FindFileData.cFileName;

	m_SongsList.AddString(sTmpPath);/* adding path to the list Box*/
					
            }
        } while ( FindNextFile( hFind, &FindFileData) != 0 );
			  FindClose( hFind );
    }
    return;
}

void CDemoDlg::OnLbnSelchangeListSongs()
{
    int sel;
    CString Song;
    sel=m_SongsList.GetCurSel();
    m_SongsList.GetText(sel,Song);
    PlaySound(Song,NULL, SND_FILENAME|SND_ASYNC);/* Play only .wav form music files*/

}
