Select items from combobox

Hello.
I have 3 items in a combobox and for the first one , when i select it i want to receive an error message. How is that possible?

You've got to process the messages sent correctly.

SendMessage(ID, CB_ADDSTRING, 0, (LPARAM) _T("Text1"));
SendMessage(ID, CB_ADDSTRING, 0, (LPARAM) _T("Text2"));
SendMessage(ID, CB_ADDSTRING, 0, (LPARAM) _T("Text3"));

There are 3 items, Text1,2,3 to the specified ID. So how can i do to call Text1 or Text2? I mean, when i select Text1 from combobox i receive an error message.

use messagebox to display the message

and use ON_CBN_SELCHANGE to fire the messagebox
