I too had this problem
I overcame it by using the requery() method on the ADOTable - however, this
would loose my place in the database so i used a bookmark to save it.. The
code looked a little bit like this:
void TForm1::DB_Refresh()
{
TBookmark SavePlace;
TExecuteOptions myOptions;
myOptions << eoAsyncFetch ;
// get a bookmark so that we can return to the same record
SavePlace = ADOTable1->GetBookmark();
// Re run the query
ADOTable1->Requery(myOptions);
// Now return to where we were before
ADOTable1->GotoBookmark(SavePlace);
ADOTable1->FreeBookmark(SavePlace);
}
