_IEAttach crashes

[StandardUser]

Good day,

I try to use _IEAttach with $s_mode = HTML:

#include <IE.au3>
Dim $oIE
While IsObj($oIE) = 0
        $oIE = _IEAttach("...some html...", "HTML")
        If IsObj($oIE) Then
 ;do some stuff
    EndIf
Sleep(1000)
Wend

If the web page I want to attach to is already present, it works fine. But if the page is just loading, the script crashes at that moment:

C:\Program Files\AutoIt3\Include\IE.au3 (456) : ==> Variable must be of type "Object".:
If StringInStr($o_window.document.body.innerHTML, $s_string) > 0 Then
If StringInStr($o_window.document.body^ ERROR
->00:03:54 AutoIT3.exe ended.rc:1
>Exit code: 1   Time: 8.053

If I use other attach modes(Title, URL, Text, etc.) it also works fine. What could be the problem? I would greatly appreciate any help, as its really driving me nuts

That's not a crash, just an error, and your script continues executing. The $o_window.document.body is not a retrievable object until the page is done loading.

Seems pretty simple: Don't try to attach by that mode before it's loaded.

Edit: More accurately, it doesn't have to be a crash. Add _IEErrorHandlerRegister().

Thanks a lot, you made my day I really forgot about _IEErrorHandlerRegister. It now prevents the script from exiting. However I think, it is not a good solution to make a buggy script work properly, but I see no other method

Why must you use only "HTML" mode for _IEAttach()? Either find it another way and _IELoadWait(), or do it in a loop (with proper error handling) until you get the one you want.

The page I want to attach to is only distinguishable by its HTML, no other attach mode is reliable, anyway, thanks for your help again!
