C++ ListBox Control.
The C++ System.Windows.Forms.ListBox control enables you to display a list of items from which the user can select one or multiple items from the list. The default is for the ListBox to list the items vertically however setting the multicolumn property to true the items are listed horizontally. The control is typically used to display data from a database. The items listed within the ListBox cannot be edited directly.
