Question:
How do I get a ComboBox to drop down its list box in code?


Answer:
Send the ComboBox a CB_SHOWDROPDOWN message, passing a 1 (true) in
the WParam parameter to drop the list down, or a 0 (false) to hide it.

procedure TForm1.Button1Click(Sender: TObject);
begin
  SendMessage(ComboBox1.Handle,
              CB_SHOWDROPDOWN,
              1,
              0);
  ComboBox1.SetFocus;
end;
