Notes

• This class allows you to manage ABL windows along with .NET forms in an ABL session. It allows ABL windows to participate in the session form chain (starting with SESSION:FIRST-FORM and ending with SESSION:LAST-FORM) and to be referenced by form-oriented ABL elements such as the ACTIVE-FORM system reference. However, all program interaction with ABL windows must still be accomplished using ABL window attributes, methods, and events on the window handle (specified by the ProWinHandle property). For information on using ABL windows along with .NET forms in your application, see Use .NET Classes in ABL Applications.
• ABL does not create an instance of this class for the ABL default window, as the default window is typically not used in a GUI application.
• ABL handles all creation and destruction for instances of this class. Therefore, instances of this class never appear on the session object chain, and their NEXT-SIBLING property and PREV-SIBLING property (inherited from the Progress.Lang.Object class) are always set to the Unknown value ( ? ).
• For information on the public class members inherited from the System.Object class, refer to the .NET Framework class library.
