Hi everybody!
I have a problem with the TComboBox component.
I've got a sorted ComboBox. To know which item is selected (because the
combobox is sorted), I first assign each item a ID through the Perform
method:

ComboBox->Items->Clear();
for (i=0; i<N; i++)
{
  pos = ComboBox->Items->Add(Name[i]);
  ComboBox->Perform(LB_SETITEMDATA,pos,i);
}

Then, when a button is pressed, I read the ID number of the selected item:

number = ComboBox->Perform(LB_GETITEMDATA,ComboBox->ItemIndex,0);

However, this last command always return 0! (whereas the value of
ComboBox->ItemIndex is correct). I really can't understand why, because I do
the same thing with a TListBox component, and it works!
Can someone tell me what is wrong?

Thank you
Zlika
