_WordAttach Cannot attach using handle in Win7

[AutoitMike]

In Win XP I am able to attach to a Word document using the window's handle.

In Win 7, 64 bit, it fails to attach. @Error is encountered.

Code:

$Handle=WinGetHandle("[ACTIVE]") ;which is a Word document window

$WordApp=_WordAttach($Handle,"HWND")

If @error then

MsgBox(0,"","An Error was encountered")

EndIf

I can , however, attach using text:

$WordApp=_WordAttach("Text in the Document", "Text")

However, I would like to know if there is a fix for this, work around, or a newer version of AutoIt

Thanks

I have been on vacation. Did you find a solution to this problem?

Yes, using title and text, but the handle mode is my preferred method. (this is in the first post)

I know this is an old topic but I think I tracked down this issue. I do not know how to "fix" it but i have a workaround. 

The function _WordAttach() calls the function __WordGetHWND() which ends up failing on my computer. I tracked it down to the line:

If Not $oWordErrorHandler.number = 0 Then Return SetError($_WordStatus_ComError, 0, 0)

If you commend out this line, it seems to "fix" the issue. 

$oWordErrorHandler.number seems to be a "random" 8 digit number. (im sure there is some logic behind what the number is, so it is probably not actually random) If the function is called more than once, (more than one word window open) it returns the same number but if you run a new instance of your application it is different. 

At this point debugging this is way over my head.

Why do you need to use the window handle to attach to Word? Wouldn't the document title or filename be a better choice?

The Word UDF of AutoIt 3.3.8.1 was completely rewritten for the next version. It is already implemented in the latest beta. It lifts the limitations but is incompatible with the current version.

_Word_Attach then no longer supports HWND as parameter.
