Wow Dug, you present it so elegantly. I will think it through some more, as
you said it is time consuming and I may want to take a different approach to
solving my problem.

Using hierarchical position to find a window is a bit time-consuming if you're
trying to get to it, but a bit less if you're just trying to identify a window
you already have.
GetWindowHierarchyX(hwnd) and GetWindowHierarchyY(hwnd) will give you an idea
where a window can be found in the hierarchy, provided you already have a
window handle. The trick here, though, is that you need the GetWindowHierarchyX
value for each level from that window up to the top, if you want to find the
window again later.
I say it's time-consuming to find the window later because there's no function
in JAWS scripting to go straight to the nth window at a level, so you have to
loop once for each level until you get to the right window for that level.
In physical terms, it's like this: I'm hiding out on a leaf.
GetWindowHierarchyY tells you I'm four branch splits from the tree trunk, and
getWindowHierarchyX tells you I'm the third leaf on my branch. The problem is,
you don't know where my branch is on the branch it comes from, or where that
one is on the one it comes from, etc. You need something like, "Go to the
second branch from the trunk, then the fifth branch from that one, then the
second branch from that, and then the third leaf on that one." This takes a bit
of doing in JAWS.

Thanks Dug for responding. I do get what you are saying. I was hoping I could
maybe find the descendent window by its position in the hierarchy and then grab
its handle from there. This may not have been clear from my original request.
Maybe this is more clear. Its may be just to cumbersome to be practical as
well.

What I'm about to say is honestly not meant to sound flippant, but I'm still
afraid it might:
Most any search tactic will require that you know what you're looking for, so
I'm having trouble identifying specifically what is troubling you.
FindDescendantWindow requires a control ID. I find useful and unique control
IDs rather scarce these days, so I usually use FindWindow instead, as it can
search by window class name, window name, or both at once. If your application
sports unique and consistent control Ids, you can use findDescendantWindow to
good advantage though.

Hi, I have been trying to figure out how to find a specific descendent window
based on higharchy but haven't clude in yet. FindDescendentWindow requires
that you know what you are looking for so this does not work for me.
Can any one point me in the right direction?
Thanks
