ADOX中判断表的存在！

ADOX::TablesPtr m_pTable = m_pCatalog->GetTables(); 
    bool bExist=FALSE;
    long x = m_pCatalog->Tables->Count;
  for (int i=0;i<x;i++)
   {
   if (m_pCatalog->Tables->Item[(long)i]->Name == _bstr_t(_T("officers")))
    bExist = TRUE;
   }
   if(!bExist)
   {

        //do what you want to do.
       }
