Jerry,

You can put in the init of the listbox something like

Bindevent(this, 'AddItem', thisform, 'CheckCombo', 1)
Bindevent(this, 'AddListItem', thisform, 'CheckCombo', 1)
Bindevent(this, 'RemoveItem', thisform, 'CheckCombo', 1)
Bindevent(this, 'RemoveListItem', thisform, 'CheckCombo', 1)
Bindevent(this, 'RowSourceType', thisform, 'CheckCombo', 1)
Bindevent(this, 'RowSource', thisform, 'CheckCombo', 1)

Then you create a CheckCombo method in your form with

thisform.ComboBox.Enabled = (thisform.ComboBox.ListCount > 0)

Of course if you are subclasing the listbox, the CheckCombo should be a method of the class.

Not sure if I forgot another event that might change the ListCount


[Update]
I forgot you need an lparameters in the CheckCombo method in order to successfully bind to the first 4 events
