Using Python to Automate Visio
There are lots of examples of automating office apps out there but Visio examples seem thin on the ground. I guess this is partly due to its relatively recent inclusion into the Office fold. The example below shows Visio code to create a diagram with two rectangles joined by a connector. Its written in Python and makes use of the win32com package provided by pywin32 . This is installed by default with ActivePython . I had some difficulty getting the makepy tool to see the Microsoft Visio 11.0 Type Library that showed up fine as a registered object in Visual Studio and Excel/VBA. In the end I had to explicitly point makepy at the VISLIB.DLL. That said the code below will work fine without this step as I don't make use of any of the Visio Constants. import os import win32com.client # Two lines below generated from the command: # python makepy.py -i VISLIB.DLL from win32com.client import gencache gencache.EnsureModule( '{00021A98-0000-0000-C000-000000000046}' , 0, ...
