Visual FoxPro 3.0 Undocumented Properties

MORE INFORMATION

Visual FoxPro uses tables to store data that defines different file types. For example, Form files (.scx) and Visual Class Library files (.vcx) are tables. Because these files are actually tables, you can use and browse them in the same way that you browse any .dbf file.

In a Form or Visual Class Library file, the Properties field stores the properties of objects in the Form or Visual Class Library. Some of the properties listed are hidden and used internally only, so a description of their functionality is not included in the documentation that comes with Visual FoxPro. These properties are described in the following table:

Property          Description

DoCreate          Hidden property of a form used for internal purposes
                  only. When DoCreate is encountered, form load
                  performance and memory utilization is optimized. If not
                  encountered, there is slightly more memory usage by the
                  form.

ErasePage         Used to support FoxPro 2.6 READ compatible forms. When
                  set to false (.F.), it specifies that objects remain
                  visible from other active READ levels.

ReleaseErase      Used to support FoxPro 2.6 READ compatible forms. It
                  determines whether a control remains on a form after a
                  READ terminates.

ReleaseWindows    Used to support FoxPro 2.6 READ compatible forms.
                  It specifies whether Release Windows was activated in the
                  FoxPro 2.6 Generate or Project Manager dialogs.
