IE browser error window not being detected

[Champak]

AutoIt Window Info sees the window, but WinExists can't.

I've tried the following and neither are seeing it:

If WinExists("Internet Explorer", "Internet Explorer has encountered a problem and needs to close.") Then
        MsgBox(0,0,"test")
        ControlClick("Internet Explorer", "Internet Explorer has encountered a problem and needs to close.", 1001)
    EndIfoÝ÷ Ù©Ýjëh×6    If WinExists("Internet Explorer", "If you were in the middle of something, the information you were working on might be lost") Then
        MsgBox(0,0,"test")
        ControlClick("Internet Explorer", "If you were in the middle of something, the information you were working on might be lost", 1001)
    EndIf

Attached are the images of what is happening. Any ideas/workarounds?

Did you verify the Title with AU3Info? I see it on screenshot, but maybe that's graphical and the real title is not displayed...?

If that doesn't help, go with class (i.e. "[CLASS:#32770]") and the text, instead of the title.

[Champak]

Yes I did verify the title. And going with class doesn't work either.

Interesting. If that is the active window, run this and see what you get:

Sleep(30000); You've got 30 sec to make the error popup active

$hWin = WinGetHandle("[ACTIVE]")
$sTitle = WinGetTitle($hWin)
$sText = WinGetText($hWin)
        
$tBuffer = DllStructCreate("char Buffer[256]")
$pBuffer = DllStructGetPtr($tBuffer)
$iBuffer = DllStructGetSize($tBuffer)
$avRET = DllCall("user32.dll", "int", "GetClassNameA", "hwnd", $hWin, "ptr", $pBuffer, "int", $iBuffer)
$sCLASS = DllStructGetData($tBuffer, "Buffer")

$iExists = WinExists("[CLASS:" & $sCLASS & "]")

$sMsg = "HWND = " & $hWin & @CRLF & _
        "Title = " & $sTitle & @CRLF & _
        "Text = " & $sText & @CRLF & _
        "Class = " & $sCLASS & @CRLF & _
        "Exists = " & $iExists & @CRLF & @CRLF
For $n = 0 To UBound($avRET) - 1
    $sMsg &= "$avRET[" & $n & "] = " & $avRET[$n] & @CRLF
Next

MsgBox(64, "Window", $sMsg)

Edit1: Updated code to get CLASS also.

Edit2: Oops. Raw DLL call was not required to get class. There is a UDF already: _WinAPI_GetClassName()

Here is the result...same info as the info window.

Here is the result...same info as the info window.

Try: WinWait("[CLASS:#32770; TITLE:Internet Explorer]")

[Champak]

Are you saying that to test to see if the same thing happens, or to use it in place of "Exists"? Because "Wait" wont work for what I'm doing, the "Exists" is going in the main loop.

Just a dumb typo on my part: I meant use that match string in WinExsists().

[Champak]

So here is what my tests have shown.

1/ The problem happens either during navigate or loadwait

2/ The winExists is not being seen in the loop because the function is not ending and going back to the loop.

3/ This only happens when the DebugBar toolbar is open...even when the window is hidden.

So I believe I would have to put the WinExists() in the LoadWait() function itself in the While loops. Is that correct?...not able to test it now.

No. If the problem is blocking of the script then use the $f_wait = False option and so your script can continue while it loads/navigates the page. Do your own non-blocking check for "busy" with _IEPropertyGet() or maybe _IELoadWait($oIE, 0, 100), in the same loop you watch for the popup with.

[Champak]

I don't know if this is what you meant, but this is what I did. I replaced the _IELoadWait() with a function call to the following:

Func _LoadWait_ErrorTEST()
    _ConsoleWrite(">!!!!! LOAD WAIT")

    $Timeout = 0
    Do 
        Sleep(1000)
        $Timeout += 1
        ;If WinExists("[CLASS:#32770; TITLE:Internet Explorer]") Then   
        If WinExists("Internet Explorer", "Internet Explorer has encountered a problem and needs to close.") Then
            _ConsoleWrite("! IE Error Window Pop Up ===========================================")
            ControlClick("[CLASS:#32770]", "Internet Explorer has encountered a problem and needs to close.", 1001)
        EndIf
        $busy = _IEPropertyGet ( $oIE, "busy" )
        ConsoleWrite("- busy loading: " & $busy & @CRLF)
    Until $busy = 0 Or $Timeout = 60
    
EndFunc

If this is what you meant(or something like it), it doesn't work. It is getting stuck at the _IEPropertyGet() WHEN that pop up window shows up; and again, the window only pops up when the debugbar is open in the toolbar in IE.

It seems the only way to fix this is to have a helper app look for this pop up window and close it so the main app can continue...or do you have another suggestion.

I meant more like this (_IEPropertyGet() was probably a bad suggestion on my part):

Func _LoadWait_ErrorTEST()
    _ConsoleWrite(">!!!!! LOAD WAIT" & @LF)

    $iTimer = TimerInit()
    While 1
        Sleep(500)
        If WinExists("Internet Explorer", "Internet Explorer has encountered a problem and needs to close.") Then
            _ConsoleWrite("! IE Error Window Pop Up ====================================")
            ControlClick("[CLASS:#32770]", "Internet Explorer has encountered a problem and needs to close.", 1001)
        EndIf
        If _IELoadWait($oIE, 250, 250) Then 
            ConsoleWrite("IE done loading: " & Round(TimerDiff($iTimer) / 1000) & "sec" & @LF)
        ElseIf TimerDiff($iTimer) >= 60000; 60sec timeout           
            ConsoleWrite("60sec timeout expired!" & @LF)
            ExitLoop
        Else
            ConsoleWrite("IE busy loading: " & Round(TimerDiff($iTimer) / 1000) & "sec" & @LF)
        Else
    WEnd
EndFunc  ;==>_LoadWait_ErrorTEST

This should check every 1sec for about 60secs.

[Champak]

Nope. That's a no go as well .
