Assembly: Microsoft.VisualBasic.Compatibility (in Microsoft.VisualBasic.Compatibility.dll)
In Visual Basic 6.0, the ListBox and ComboBox controls use a List property to store list items and an ItemData property to optionally store an Integer associated with each list item. In Visual Basic 2008, the ListBox and ComboBox controls use the Items property to store list items, and the ItemData property is no longer supported.
When a Visual Basic 6.0 application is upgraded to Visual Basic 2008, the upgrade tools create a ListBoxItem class for each item in a ListBox or ComboBox control. The SetItemData and GetItemData functions can then be used to enable any code that references the ItemData property.
Functions and objects in the Microsoft.VisualBasic.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic 2008. In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.
