Is that right ?

int index_test = 0;
for(Vector<TownLs>::Iterator q = ls_town->Begin(), e = ls_town->End(); q != e; q++)
{
TownLs temp = *q;
if(temp.getName() == "Pancevo")
break;
index_test++;
}
PromptOK(AsString(index_test)); // index

//desc: ls_town is pointer (Vector<TownLs>)

Better method, any?

Thanks.

Hi exdatis,

You can write it without the ugly iterators as

int index_test;
for(index_test = 0; index_test < ls_town->GetCount(); index_test++){
	if((*ls_town)[index_test].getName()=="Pancevo") break;
}
PromptOK(AsString(index_test));

There are probably even better/faster solutions, but those would depend on how TownLs class looks like...

Best regards,
Honza

EDIT:Oups, I missed that ls_town is a pointer Embarassed

Corrected now Wink

Thank You!
That's right!
//
TownLs is a simple,
id and town_name, ... (db.table) ,couple methods.
and Vector* is arg for others (fill drop_grid in some form/class).
index, just for update(
if(*q.GetId() == int_town_id) break;
), append is easy.
//
Is that ok?
