You should look at the messages related to change of selection in the 
dialog box.  If I recall right, it's EN_SELCHANGE, or something like that.
When you get it, then you can do whatever.  The actual message you get is
the control's ID (forgive me if this is not quite right; I'm doing it from
memory) with  the notification message in a parameter.  Or maybe it's
WM_COMMAND with the ID in wParam and the notification in lParam.  In any
event, it's the standard notification message, and the selection change
notification is the ticket.
