mcisendstring里面先open了，然后play
play ="play.....+notify";
hwnd=this->m_hWnd;
mciSendString(play, NULL, 0, hwnd);
响应函数
LRESULT CLrsfMusicDlg::OnMCINotify(WPARAM wParam, LPARAM lParam)
{
/*if (MCI_NOTIFY_SUCCESSFUL == wParam)
{
MessageBox(L"播放完毕",L"提示");
}*/
//MCI_NOTIFY_SUCCESSFUL == wParam
MessageBox(L"播放完毕", L"提示");
return FALSE;
}
可就是不弹出消息框啊！
不懂mfc消息传递机制，是哪里写错了
