获取ACCESS2000数据库中所有表的名称

  调用方法:
  
  CString strFileName;
  TCHAR FileName[MAX_PATH];
  TCHAR bigBuff[2048] = _T(""); // maximum common dialog buffer size
  TCHAR szFilter[] = _T("Text Files (*.mdb)|*.mdb|All Files (*.*)|*.*||");
  CFileDialog dlg(TRUE, NULL, NULL,
  OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT, szFilter);
  
  // Modify OPENFILENAME members directly to point to bigBuff
  dlg.m_ofn.lpstrFile = bigBuff;
  dlg.m_ofn.nMaxFile = sizeof(bigBuff);
  
  if(IDOK == dlg.DoModal() )
  {
  strFileName = dlg.GetPathName();
  lstrcpy(FileName,strFileName);
  OpenSchemaX(FileName);
