Problems with IEAttach: Return HWnd($o_object.HWnd())

Recommended Posts

Ok this started out of nothing i wasn't even coding.. just running the program. actualy i had just closed and started it again.

>"C:\Arquivos de programas\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.exe" /run /prod /ErrorStdOut /in "G:\Monsters Hive\src\Main.au3" /autoit3dir "C:\Arquivos de programas\AutoIt3" /UserParams

Here is where the code stops

$AccInfo[$i][0] = WinGetHandle($AccInfo[$i][1])

For $i = 0 To $AccCount - 1
        _GUICtrlListBox_ReplaceString($MonstersConsoleOutput, $i, $i & " - " & $AccInfo[$i][1] & ": Acquiring Internet Explorer Handle")

        $AccInfo[$i][0] = WinGetHandle($AccInfo[$i][1])

        WinSetTitle($AccInfo[$i][0], "", "Handle Acquired.")
        _GUICtrlListBox_ReplaceString($MonstersConsoleOutput, $i, $i & " - " & $AccInfo[$i][1] & ": Internet Explorer Handle acquired: ( " & $AccInfo[$i][0] & " )")
;~      WinSetState($AccInfo[$i][0], "", @SW_MINIMIZE)
    Next;==>AccountManager (Here we get the WinHandle from the array and attach to IE)

the program stops on the first FOR.

Edit: forgot to mention about the arrays:

$AccInfo[$i][1] = Title of IE Window (also account name)

$AccInfo[$i][0] = IE Window Handle

You mention _IEAttach in the title, but your code sample shows no reference to any _IE function calls.

One likely cause of such an error is that the browser is closing or is in the process of navigating to a new location or for one reason or another is not standing still. You do not provide enough information to provide any specific help, but perhaps these ideas will help you with your troubleshooting.

If this has worked and suddenly is not, another possibility is a misbehaving iexplore.exe process. In this case, logout and back in and see if the issue persists.


Edit: rewrite after remembering that _IEAttach hwnd calls _IEPropertyGet hwnd

Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?

oh sry I posted the wrong for..

For $i = 0 To $AccCount - 1
        _GUICtrlListBox_ReplaceString($MonstersConsoleOutput, $i, $i & " - " & $AccInfo[$i][1] & ": Attaching to Internet Explorer...")

        $AccInfo[$i][3] = _IEAttach($AccInfo[$i][0], "HWND")

        _GUICtrlListBox_ReplaceString($MonstersConsoleOutput, $i, $i & " - " & $AccInfo[$i][1] & ": Attaching to Internet Explorer... Done.")
        $AccInfo[$i][4] = 0
        $AccAction[$i][4] = 0
        _GUICtrlListBox_ReplaceString($MonstersConsoleOutput, $i, $i & " - " & $AccInfo[$i][1] & ": Attaching to Internet Explorer... Done.")

and after a system reboot is started working again. so i guess it was a windows bug not autoit =/

But thx for the reply

I just got exactly same error. Even it's because of the Windows OS, can we have a handler instead of just crush?

Did you try _IEErrorHandlerRegister()?
