Automation classes... Help!

Hi guys,
I am experimenting with the automation classes but I have some questions:

- Is it possible to do a search for an element by using wildcards in
findfirst/findall?
e.g. I would like to search for "TestWindow*" which would then return either
the first window it finds or all windows that match that ciriteria.
(TestWindow1,TestWindow2,...)

- The treescope defines ancestors & parent, but where can I use these? I
only get invalidparam when I try to use them in findfirst/findall. So how
can I get the parent of a control without using win32?

- Is there any way to control a window without having to use it's name? A
control is simple because it has an automation ID, but the automationd id of
a window is always empty so the best I can use to describe it, is using the
name. But the problem with that is that it isn't very useable when trying
another language of the application.

PS: I use the January CTP.

Best Regards,
Nick
