As usual:

TADODataSet *rs = new TADODataSet(NULL);
try
{
  rs->Connection = frmFrame->adoConnection;
  //This may be set in designer or on connection-related code.
  rs->Connection->LoginPrompt = false;
  rs->CommandText = sql;
  rs->Open();
  try
  {
    ..
  }
  __finally
  {
    rs->Close();
  }
}
__finally
{
  delete rs;
}
