December, 2024, two months later
On and off I have been looking a bit more at all this VBA windows API stuff, and got a few insights, comments etc., in a few places such as here
2024:

http://www.eileenslounge.com/viewtop...321838#p321838 It works by ensuring that the 'Clear All' button is displayed on the screen, then searching through the windows hierarchy find the window that represents the panel that contains the button, then obtains the Accessibilty COM interface for that button (by looking for what control with an Accessibility interface is at a specific point, first ensuring that nothing unexpected is covering that point), and then uses that Accessibility interface to invoke the (default) action the button(hopefully the 'Clear All' button).

It's just a different route to the same thing - the 'small' code walks through the relevant part of the application's accessibility hierarchy instead of having to search for relevant windows, and ends up at the same point - an Accessibility COM interface to the 'Clear All' button (well, depending on the version of Office ...)

http://www.eileenslounge.com/viewtop...322075#p322075 …. window from a programmers perspective: …. Parent-Child Relationships: Windows can have hierarchical relationships. A parent window can host multiple child windows, organizing the interface within a main container. This setup is commonly seen in forms containing controls such as buttons, text boxes, or custom graphics elements. ……the Windows API provides us with tools (Win32 API functions such as FindWindow and FindWindowEx)) that let us walk that hierarchy, but they do NOT give us tools to jump direct to any window we want.

But here’s the thing – not every window we see is necessarily a Windows window (by which I mean one that is managed by the OS), and that means the standard functions cannot walk the tree.

This is the root cause of the difference in methodology between ‘big’ and ‘small’ code examples you've been looking at

One is trying to walk the classic hierarchy – and runs into trouble when it hits NetUIHWND, because that is the bottom of the barrel, there are no children. (Which is why Spy+ and all the Spy+ workalikes such as WinSpy fail here – there’s no more hierarchy for them to walk and display)

The other recognises this problem, and works on the fact that the Ribbon interface maintains its own hierarchy, and that hierarchy is sort of exposed by the Accessibility interface (iAccessible). So, instead of walking down the classic windows tree, we walk down the hierarchy presented to the iAccessible interface. It has the same limitations - there is no way to jump direct to a specific element in the hierarchy; you have to use the functions provided by the oleacc dll. (Accessibility can also be used to walk the classical windows hierarchy)
