Saved Property [Visio 2003 SDK Documentation]
Determines whether a document has any unsaved changes.
boolRet = object.Saved
object.Saved = boolExpression
boolRet Boolean. True if the document has no unsaved changes; otherwise, False.
object Required. An expression that returns a Document object.
boolExpression Required Boolean. True to indicate the document is saved; False to indicate unsaved changes.
Use caution when setting the Saved property for a document to True. If you set the Saved property to True and a user, or another program, makes changes to the document before it is closed, those changes will be lost—Microsoft Office Visio does not provide a prompt to save the document.
A document that contains embedded or linked OLE objects may report itself as unsaved even if the document's Saved property is set to True.
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the Saved property to determine whether a document has any unsaved changes. It also shows how to set the Saved property. Before running this macro, change path to the location where you want to save the drawing, and change filename to the name you'd like to assign the file.

Set vsoShape = vsoPage.DrawOval(4, 7, 5, 9) 'Use the Saved property to verify that the document changed 'since the last time is was saved. 'Saved returns False (0) Debug.Print ThisDocument.Saved 'Use the Save method to save any new changes. ThisDocument.Save 'Use the Saved property again to verify that 'the document was saved.

Set vsoShape = vsoPage.DrawRectangle(1, 1, 7, 7) 'Set the Saved property to True. 'Setting the Saved property to True does not save the document. ThisDocument.Saved = True 'Close the document and then reopen it. Note that 'the rectangle was not saved.
