程序运行到下面这段代码的时候，
void CRemotePlaybackDlg::OnDestroy()
{
     
    vector<H264_DVR_FILE_DATA*>::iterator p=m_pstrFileVector.begin();
     if ( p )
     {
         H264_DVR_FILE_DATA* pData = (*p);
         delete pData;
         pData = NULL;
     }
     
    ClearResult();
     ClearMapResult();
     KillTimer(1);
     CDialog::OnDestroy();
 }
系统提示“if （p）”这里出现提示“类型的条件表达式是非法的”这样的错误，如下：
error C2451: “std::_Vector_iterator<_Ty,_Alloc>
with
1>        [

求高手来帮忙解答一下
