_IEAction($fileField, "click") is blocking further execution

[mgeorg]

Hi everybody,

I'm trying to automate uploading files via a internet explorer form. To do that I click the field where you can enter the path to the file with

_IEAction($fileField, "click")

which actually opens a window, where I can manually select the file to upload. However it blocks the further execution of my code.

It would be great is someone here could tell me, how I can load the "upload file" window from IE without blocking further execution or give me a hint about some other way, to upload a file via internet explorer form. (Other ways of file upload are not possible in my environment, because of security issues.)

Thanks in advance,

- Michael

as far as i remamber automating type='file' will not work with _IE coz ie8+ are construtced not to support something like that (upload spam-viruses and something similar wos the reason)

Hello bogQ,

thanks for your feedback. Wouldn't it be possible to introduce some kind of parallelism into the script to, e.g. with ChildProc.au3 (see ) to handle the popup window, even so the main program flow is blocked?

Sadly, yet I don't really understand how that ChildProc is working.

Using a separate thread to handle the upload window was indeed successful.

Following code enables automated upload of a file at $fullFilePath (at least for german windows - for english you would need to replace "Datei zum hochladen auswählen" by the english title of the upload window.

;new thread to handle upload window after blocking browse call
$uploadWindowThreadStart = DllCallbackRegister('AdditionalUploadWindowThread', 'int', 'ptr')
If $uploadWindowThreadStart == 0 Then
MsgBox(0x10, "Error", "DllCallbackRegister failed")
Exit
EndIf

Func AdditionalUploadWindowThread($void)
While True
     $uploadWindowHandle = WinGetHandle("Datei zum Hochladen auswählen")
If ($uploadWindowHandle = 0) Then
     Sleep(1500)
     Else
     ControlSend($uploadWindowHandle, "", "[CLASS:Edit; INSTANCE:1]", $fullFilePath)
     ControlClick($uploadWindowHandle, "", "[CLASS:Button; INSTANCE:2]")
     ExitLoop
     EndIf
WEnd
EndFunc


;start thread that handles file upload popup and press browse button
DllCall("kernel32.dll", "hwnd", "CreateThread", "ptr", 0, "dword", 0, "long", DllCallbackGetPtr($uploadWindowThreadStart), "ptr", 0, "long", 0, "int*", 0)
_IEAction($fileField, "click")

Hi Dale,

thank you, I guess your solution is much better than mine, because you don't need a separate thread this way.

Anyway, to get the solution with a separate thread running stable, I needed to remove the while loop from the additional thread and instead using the following code:

Func AdditionalUploadWindowThread($void)
  $uploadWindowHandle = WinGetHandle("Datei zum Hochladen auswählen")
  If ($uploadWindowHandle <> "") Then
  ConsoleWrite("got handle for upload window" & @CRLF)
  ControlSend($uploadWindowHandle, "", "[CLASS:Edit; INSTANCE:1]", $fullFilePath)
  ControlClick($uploadWindowHandle, "", "[CLASS:Button; INSTANCE:2]")
  Else
   Sleep(1000)
   $uploadWindowHandle = WinGetHandle("Datei zum Hochladen auswählen")
   If ($uploadWindowHandle <> "") Then
   ControlSend($uploadWindowHandle, "", "[CLASS:Edit; INSTANCE:1]", $fullFilePath)
   ControlClick($uploadWindowHandle, "", "[CLASS:Button; INSTANCE:2]")
   EndIf
  EndIf
EndFunc

Can anyone in here explain to me, why the program gets stuck sometimes, if I use a while loop with a sleep command instead of executing the same commands again in the else path?
