_EnumChildWindows
Enumerate controls/children of a Window

This code enumerates all controls/children of a given Window and returns them in an array.
Example code is included.

*small change 9/15/2010:

• removed a #include line from the example code posted here (not required)

*update 3/28/2010:

• Control ID is now retrieved. Unfortunately the indexing was reworked (sorry). But at least now I believe all the relevant information needed is retrieved.
• Parameters to the function now have a slightly different meaning. Basically, this was done to allow searching for controls with an empty-string for a Title. All defaults are now 0, so a call can be made like this to find all Controls with a 'Button' classname:
  _EnumChildWindows($hWnd,0,0,"Button")

; Important to wait for the window to fully 'create' itself before getting child windows!
; Note that other processes that become activated somewhere between _WinWaitEx and this will cause WinWaitActive() to wait for manual activation
;WinWaitActive($hWnd)   ; bad idea in busy environment
WinActivate($hWnd)  ; this seems to be a better alternative, the window seems fully created after this is called in my tests

If @Error Then Exit ProcessClose($iCalcPID)

; Find specific items [Certain versions of Calc won't return any text]
For $i=1 to $aEnumList[0][0]
    Switch $aEnumList[$i][3]

While I provide this source code freely, if you do use the code in your projects, all I ask is that:

• If you provide source, keep the header as I have put it, OR, if you expand it, then at least acknowledge me as the original author, and any other authors I credit
• If the program is released, acknowledge me in your credits (it doesn't have to state which functions came from me, though again if the source is provided - see #1)
• The source on it's own (as opposed to part of a project) can not be posted unless a link to the page(s) where the code were retrieved from is provided and a message stating that the latest updates will be available on the page(s) linked to.
• Pieces of the code can however be discussed on the threads where Ascend4nt has posted the code without worrying about further linking.

dude u rock.

[wakillon]

Where can I find the needed include _WinWaitEx.au3 ?
I don't find it on your website...

[Ascend4nt]

wakillon, sorry - that was a remnant from the example before it was modified. It's not required for the code to run, but I realized I left that '#include' statement in there. It's removed now, however, and should run. The code in the ZIP file on my site shouldn't have it either.

Thanks for pointing it out.
