Documents.BeforeDocumentSaveAs Event (Visio)
Occurs just before a document is saved by using the Save As command.
The BeforeDocumentSaveAs event fires when a document is saved to either a native format (for example, VSD or VDX) or a non-native format (for example, HTM or BMP). It does not fire when a document is saved to DWG, DXF, and DGN formats. To save a document in a non-native format programmatically, you must use the Export method of the Page object. Note that when you call the SaveAs method, Microsoft Visio fires first the BeforeDocumentSaveAs event and then the DocumentSavedAs event. Calling the Export method, however, fires the BeforeDocumentSaveAs event but not the DocumentSavedAs event that follows it in response to the SaveAs method.
The BeforeDocumentSaveAs event is one of a group of events for which the EventInfo property of the Application object contains extra information.
If the BeforeDocumentSaveAs event is fired because a save was initiated by a user or a program, the EventInfo property returns the following string:
If it fires because Visio is saving a copy of an open file (for autorecovery or to include as a mail attachment), the EventInfo property will return one of the following strings:
If the event is fired for autorecovery purposes, the name of a recovery file in this format: "/autosavefile=C:\TEMP\~$2VSO2FD.vsd"
If the event is fired because a document copy is being made to send as a mail attachment, the name of an attachment file in this format: "/mailfile=C:\TEMP\~$2VSO2FD.vsd"
If you are using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
If you are handling this event from a program that receives a notification over a connection by using the AddAdvise method, the vMoreInfo argument to VisEventProc designates the document index: "/doc=1".
