They fire because something specific happened. If it happens, the event fires. :-) Before you can move from a control dBASE has to check to see if the next control can accept focus. The when event handler decides if the target control can accept focus so the when event for the CBN control fires before focus actually leaves CBM. The act of leaving CBM can (and will) trigger events for CBM after CBN when has fired. In any case CBM onChange should fire immediately you select a new entry in CBM whether you move to a new control or not. onChange will fire for each item as you scroll down the list. onChangeCommitted, on the other hand, will only fire if you click on the item or press enter. onChangeCommited doesn't fire if you scroll down to an item and then press tab. This could cause problems. :-( Mervyn. | |
