How to close instance of an XML DOCUMENT?

Word 2007,how to automatically increase number?

• For instance, if you have document that starts whit lets say: document no 1, how to make, that when you close and open that document again it increases to: document no 2, and when opened again to document no 3 etc... I know how to make it in excel, but have no clue for word... Big thx in advance to anyone who can help

• Answer:

  There is no built-in unique document numbering feature in Word, but one could be cobbled together with a special Word template that contained some Visual Basic for Applications (VBA) code. The code would run whenever a new document was created from the template, and would increment a template variable or property, then assign it to the new document. Other than that, sorry, no.
