Class Browser Properties

  • Artículo

The following properties are associated with the Class Browser. For more information, see How to: Customize the Class Browser and Class Browser Window.

Note

Properties marked as "Reference only" or "Internal use only" are maintained internally and used by the Class Browser. Avoid changing the value of reference-only properties; you might cause errors in the Class Browser.

    Returns the alias of the work area within the Class Browser data session associated with the selected class in the class list. By default, the Class Browser private data session opens at least two table aliases: BROWSER and METADATA. The BROWSER alias is for Browser.dbf and is shared for all instances. The METADATA alias is for the class library (.vcx) or form (.scx) open in the Class Browser. If more than one file is open, the METADATA alias is incremented once for each open file.
