Saving

Document.Save

If the document or template hasn't been saved before, this method will display the Save As dialog box and prompt the user to save the file.

Application.ActiveDocument.Save 
ActiveDocument.Save 
Application.Documents("document.doc").Save 
Documents("document.doc").Save 
objDocument.Save 

If the user presses the Cancel button on the SaveAs dialog box then an error will be generated.
To prevent this error you must catch the error and ignore it by using an On Error .. Command.

Document.Saved

This property indicates if there are any unsaved changes in the document
It can also be set as a way of getting a document to close without a "do you want to save changes" prompt
Changing the property to True will flag the document as clean and disable the save button

End if
