ADQuery Eof doesn't work? 2012/05/20 10:22 (12 Months ago)

"TADQuery *MetaQuery"

Everything works except "MetaQuery->Eof". When it gets to the last record instead of breaking out of the while statement, it repeats forever the last record??? Driving me crazy...Any sugestions? Thanks

Code:

Mod->MetaQuery->FindFirst();

 while(!Mod->MetaQuery->Eof)   //fix

{

field = Mod->MetaQuery->Fields->Fields[0]->AsString ;

item2 = Tree->Items->AddChild(item,field);

item2->ImageIndex = 7;

item2->Focused = true;



for (f=1;f<Mod->MetaQuery->Fields->Count ;f++)

{

Tree->Cells[f][item2->AbsoluteIndex]= Mod->MetaQuery->Fields->Fields[f]->AsString;

}



Mod->MetaQuery->FindNext();

}

Hello When FindNext does not found a record, then the current dataset position remains unchanged. So, staying on the last record, Eof is False. FindNext fails, position remains unchanged, Eof remains False. With FindFirst / FindNext you should use Found property instead of Eof.
With best regards, DA-SOFT Technologies Support Team
