VC怎么捕获Windows Media Player的编码器异常

VC如何捕获Windows Media Player的编码器错误？
有时候播放文件的时候，Windows   Media   Player经常提示“视频或音频编码器错误”，我如何才能捕获到这个错误信息呢？谢谢

ON_EVENT(CDetailDlg, IDC_MP, 5501 /* Error */, OnErrorMp, VTS_NONE)
void OnErrorMp()
{
CWMPError theWMPError=m_myPlayer.GetError();
CWMPErrorItem theWMPErrorItem=theWMPError.GetItem(0);
TRACE(_T( "\nErrCode:%d ErrDesc:%s\n ErrURL:%s\n "),
theWMPErrorItem.GetErrorCode,
theWMPErrorItem.GetErrorDescription(),
theWMPErrorItem.GetCustomUrl());
}
