Externally refreshing category tree

[paulr00001]

I am looking for a way to programmatically cause a refresh of Categories in XnViewMP.

I change metadata externally, and just need to "Refresh" the displayed Categories. Executing View/"Update catalog from files" works, but I'd like to do this automagically.

Would I need to use something like AutoHotkey or is there a better way?

Would updating the sqlite DB instead of metadata in files work any better? (With this method, I still need to View/"Update files from catalog" to see the updates.)

Any tips/tricks/advice?

Regards,
Paul.
