Addon.Enabled Property

Visio Automation Reference

Determines whether or not an object is currently enabled. Read/write.

Version Information
 Version Added:  Visio 4.0

Syntax

expression.Enabled

expression   A variable that represents an Addon object.

Return Value
Integer

Remarks

You can get and set the Enabled property of an Event object. An Event object that is disabled does not perform its action when its event occurs.

An add-on implemented by an executable (EXE) file always reports itself as enabled. An add-on implemented by a Visio Solutions Library (VSL) file reports itself as enabled or disabled according to the enabling policy that the VSL file has registered for that add-on.

You can't tell an add-on to enable or disable itself. Visio will not send a run message to a disabled add-on. The name of a disabled add-on on a Visio menu appears dimmed.

Example

This example shows how to use the Enabled property to enable hiding or showing a toolbar. The example adds a custom toolbar to the Toolbars collection. This toolbar appears in the Visio user interface and is available while the document is active.

To restore the built-in Visio toolbars after you run this macro, call the ThisDocument.ClearCustomToolbars method.
