How to detach from _IEAttach ?

[tonycst]

If attached _IEAttach closes, script exits with <IE.au3> related error

Is there a way to detach ?

_IEQuit ( ByRef $oObject ) is not good. It will close the internet browser and i dont want that. I just want to detach from it so my script wont crash if attached window closes or disappears.

 

Thanks

Can you elaborate because I don't quite understand what you are saying?  

Post your code or a simple reproducer to demonstrate the issue you are attempting to resolve.

        If WinExists($WorkingWindowTitle) = 0 Then ExitLoop
        If _IEPropertyGet($IE, "busy") = 1 Then
            If WinExists($WorkingWindowTitle) = 0 Then Exit ;exit before crush occures inside loadwait function.
            $Wait = _IELoadWait($IE);not sure if timeout solves the crash
            If $Wait = 1 Then
                ConsoleWrite(@CRLF & "_IELoadWait passed. BEEP is next.")
                SoundPlay($BeepSound,1)
            EndIf
        EndIf

    If WinExists ($ErrorWinTitle) = 1 Then _BeeperCloseErrorWindow()
WEnd
Func _BeeperCloseErrorWindow()
    SoundPlay($BeepError, 1)
EndFunc   ;==>_BeeperCloseErrorWindow

I do attach before the loop

In the loop i constantly monitor page busy status so i can play a sound every time page refreshes and loads.

This is for inventory receiving. Each item received updates the page, so i monitor the page to get busy and loaded so i know it was updated.

As soon as the page Title changes or window closes, script crashes because _IEPropertyGet($IE, "busy") does not get any value from $IE = _IEAttach($WorkingWindowTitle, "Title").

 

I dont think i want to run $IE = _IEAttach($WorkingWindowTitle, "Title") in the same loop, do i ?

after you make that call to wait, don't you need to check for @error > 0, see the help file for return codes

https://www.autoitscript.com/autoit3/docs/libfunctions/_IEPropertyGet.htm

https://www.autoitscript.com/autoit3/docs/libfunctions/_IELoadWait.htm

check and post msgbox for errors and post back with what you find

and maybe you do want that inside the loop. I can't test to find out, but you would break if error, else attach.

I dont know how to use @error sorry. Its response would not matter to me anyway.
All i know is that $Wait = _IELoadWait($IE) crashes because attached $IE = _IEAttach("Transfer", "Title") no longer exist. It cant check none existent page. Adding exitloop before _IELoadWait, but once _IELoadWait started to wait, not much i can do.

 

 

I found another issue that prevents me from getting this script to work as expected.

I found that the error messages that pop on the screen (from the web page) i am trying to close, show up AFTER page is fully loaded.

Those messages pop in the middle of page loading process.

So when i use $Wait = _IELoadWait($IE), script is paused and waiting for the page to load. Its before the page loaded i get those warning and now i have no idea how to get the $Wait = _IELoadWait($IE) to work in a loop rather then pausing the script.

 

 

So i guess what i need is to figure out how to check for page from becoming busy to done (done loading) in a loop without pausing the script with  _IELoadWait($IE).
Is it even possible ?

Here is what i have.

$IE = _IEAttach($WorkingWindowTitle, "Title")
While 1
    If WinExists($WorkingWindowTitle) = 0 Then Exit ;exit before crush occures inside loadwait function.
    If _IEPropertyGet($IE, "busy") = 1 And _IELoadWait($IE) = 1 Then ;Page went into loading something
        ConsoleWrite(@CRLF & "_IELoadWait passed. BEEP is next.")
        SoundPlay($BeepSound,1)
    EndIf
WEnd

I get a messages from the page in the middle of page loading, so i cant detect that window and close it because script at that point is stuck waiting for page to load completely.

Any way to catch error messages that pop on the screen while page is not yet loaded ?
