Hello -
I've been trying to execute a small script from outside an ArcMap session - simply adding a layer and refreshing symbology, and nothing seems to work. The .mxd is open, and I am trying to add a newly layer and refresh the TOC by using this script from either another mxd document (as a tool), or just running it in the IDLE environment / CMD prompt. Is this not possible? The createLayerFile() creates the layer, but nothing is added or refreshed in the TOC.
However, when I add the code to the python window of the map doc I want to edit, or run it as a tool from that same map doc, it runs fine. I'd like to be able to this without having to run it from that specific map document - so I can simply open the .mxd (os.startfile), add the layer I create, and update the symbology.
Again, the tool works fine if I run it from the .mxd being edited, but I'd like to be able to do this without digging through the folder of maps I want to edit, and just open it using the script.
I hope this makes sense ... Thank you!
