You can use the ItemsSelected property to return a reference to the hidden ItemsSelected collection. This hidden collection can be used to access data in the selected rows of a multiselect list box control.
Remarks
The ItemsSelected collection is unlike other collections in that it is a collection of Variants rather than of objects. Each Variant is an integer index referring to a selected row in a list box or combo box.
Use the ItemsSelected collection in conjunction with the Column property or the ItemData property to retrieve data from selected rows in a list box or combo box. You can list the ItemsSelected collection by using the For Each...Next statement.
For example, if you have an Employees list box on a form, you can list the ItemsSelected collection and use the control's ItemData property to return the value of the bound column for each selected row in the list box.
Tip To enable multiple selection of rows in a list box, set the control's MultiSelect property to Simple or Extended.
The ItemsSelected collection has no methods and two properties, the Count and Item properties.
