Can I put a negative value in the ItemData Property?
The listbox's ItemData is initialized with positive numbers which I will not know what they are as they are initialized in the ItemData property at the time the Listbox.AddItem is executed.
Later if certain circumstances arise I want to make the value negative to indicate that this entry is not to be used until it's ItemData property becomes positive again
If yes, how do I make a positive number negative and a negative number positive?
