Document.Stat Property (Visio)
Returns status information for an object. Read-only.
If an object is a reference to an entity in a document, and if that document closes, the Stat property returns a value in which the visStatClosed bit is set.
If an object is a reference to an entity that has been deleted, the Stat property returns a value in which the visStatDeleted bit is set.
A Component Object Model (COM) object, such as a Microsoft Visio Document object, lives as long as it is held (pointed to) by a client, even if the object is logically in a deleted or closed state.
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the Stat property to check the status of a Document object. Executing the macro prints 0 (visStatNormal) and then 8 (visStatClosed) in the Immediate window.
