Contains the number of items in the list portion of a ComboBox or ListBox control. Not available at design time; read-only at run time.
Remarks
Example
The following example creates a list box. The source of the items that appear in the list box items is an array; the array is specified with the RowSourceType and RowSource properties.
ListCount is used to cycle through all of the items specified by the List property of the ComboBox or ListBox.
The MultiSelect property for the list box is set to true (.T.), allowing you to make multiple selections from the list box. The ListCount property is used within a FOR ... ENDFOR loop to display the item or items you choose in the list box. The Selected and List properties are used to determine the items you chose.
