ActiveX Listbox events do not fire

Hi there,

I've got a form in an Excel VBA program that contains listboxes displaying user selections. When these listboxes are emptied, I want to disable a commandbutton on the form to prevent the user from continuing without having selected an item. Correspondingly, I want to enable this commandbutton as soon as something is written to the listbox again. All adding/deleting of items in the listbox is handled by the code.
I thought this was easy to achieve using events, but neither the listbox_change event nor the listbox_afterupdate event fires when an item is added to or removed from the listbox. Why not? What kind of event should I use?

best regards,
Einar

wait...
what's addin stuff to your listbox ? I mean, listbox is populated via code isn't it ? you dpn't need an even for it...
also, only for the sake of checking everything, is the event handler turned on?

Application.EnableEvents = True

Fernando,

I could write code in each and every routinge that manipulates the contents of the listbox, but it would be a whole lot easier to write it once and for all in an event handler.
....as far as I know, the application.enableevents property does not affect ActiveX-events. It is only applicable to events of objects inherent to Excel.

There is no event specifically related to adding an item to a listbox, so I would agree that the code adding the item should call whatever you want triggered.

Thanks guys,

VBA seems to be unable to handle this, so let's close the thread.
