nItemID |
Returns an ItemID for a given Index number. |
Remarks
Applies To: ComboBox | ListBox
Each item added to a ComboBox or ListBox has two identification numbers assigned to it:
-
The nItemID, a unique identification number.
-
The nIndex, an integer corresponding to the order in which items are displayed by the control: The first item in the list corresponds to nIndex = 1.
Initially, as items are added to the control, these two numbers are identical. But as items are sorted, removed, and added, these numbers are no longer identical.
Use the IndexToItemID method to return the nItemID number for a particular item in the control when you know its nIndex number.
