 ADOQtmp->Close();
 ADOQtmp->SQL->Clear();
 ADOQtmp->SQL->Add("select * from t1 ") ;
 ADOQtmp->Open();
 ADOQtmp->Append();
 ADOQtmp->FieldByName("f1")->AsInteger=4;//breakpoint
 ADOQtmp->FieldByName("f2")->AsInteger=4;
 ADOQtmp->Post();

when I point the mouse to the breakpoint, the popup message told me:
ADOQtmp->FieldByName("f1")->AsInteger = E2122 function call terminated by
unhandled exception 0fxeedfade at address ....
so i think it is because some kind of hide bug.

thanks for help.
