I have looked at ActiveControlList but unfortunately it wasn't a reliable way to tell the active ribbon. Specifically, I am looking for a reliable way to tell if Equation Tools ribbon is active in OneNote. Do you have any suggestions ?
The ribbon is not a normal control and can be hard to work with from plain VBA or ahks built-in COM but you can use Microsoft's Active Accessibility API
You Can use the Acc lib so you don't need to know all the dll calls
But you still need to know what parts you need, and also what to look for to really use it. You can use jethrows AccViewer it will tell you the elements Role, State, ChildCount and more, so when you have found the item you're after, you can use the Tree or path that the accViewer gives.
Word ribbon path Example: 4.3.4.1.4.1.4.1.4.1.4.13.1.1
OneNote: 4.3.4.1.4.1.4.1.4.1.4.10.1.1
Here is an example using Acc_get() to show the current ribbon Name in OneNote PP 2010 when you press F6
f6::
name := Acc_Get("Name", "4.3.4.1.4.1.4.1.4.1.4.10.1.1", 0, "Ahk_class Framework::CFrame")
tooltip % name
return
Note: that this path is for when the ribbon is pinned i.e always visible
