IE UDF unexpected behavior on Windows Server

Recommended Posts

On local machine some code works just fine. On Windows Server 2012 exact same code doesn't work. I wrote a demo code, but this applies to more cases where form submit event is involved and browser logs in into user's account. 

Demo code:

#include <IE.au3>

; with 'Local' exact same result (no wonder)
Global $oIE = _IECreate("http://ukrgo.com")
_IELoadWait($oIE)
    
; maximize window
Local $ie_hwnd = _IEPropertyGet($oIE, "hwnd")
WinSetState($ie_hwnd, "", @SW_MAXIMIZE)
  
; extra safety for DOM loading etc.
Sleep(5000)
  
; authorization form
Local $oFormAuth = _IEFormGetCollection($oIE, 0)
  
; login and pass
Local $oFieldLogin = _IEFormElementGetObjByName($oFormAuth, "login")
Local $oFieldPass = _IEFormElementGetObjByName($oFormAuth, "password")
_IEFormElementSetValue($oFieldLogin, "auto56216879")
_IEFormElementSetValue($oFieldPass, "nlzdouByNDjx7AbhWcPL")
Sleep(50)
  
; form submit
_IEFormSubmit($oFormAuth)

; extra safety for DOM loading etc.
Sleep(5000)
  
; click the link
_IELinkClickByText($oIE, "Стройматериалы")


On local machine code fires last action (click) and this element is clicked. On Windows Server exact same code doesn't produce this click for some reason.

Of course, latest version of Autoit is installed inside Windows Server and is run from there, not from local machine. RDP connection is used to control server and to launch .au3 scripts there.

For me it looks like Autoit looses object handle and $oIE starts pointing nowhere (or on some other thing). But even if i try to re-initialize IE object and then call click action, still nothing happens: 

; all code before click action (see it above)
$oIE = _IEAttach("Оголошення")
_IELinkClickByText($oIE, "Стройматериалы") ; again, this action is not performed


Some strange things which might matter: 
On server UAC is turned off completely, user is admin, Enhanced security of IE is disabled.
If code is compiled as exe and run as admin same results happen.
Local machine is Windows 10.

What are the IE versions on Server and Workstation? Do you have SCITE output from the server ? It should be a warning that

_IELinkClickByText($oIE, "Стройматериалы")

Failed because it didnt find the link (i guess).

Servers have a bunch of stuff turned off by default for security and performance reasons. I don't recall what, but I've had to turn on some things to get scripts to run on them.   maybe a quick Google will do you.


IEbyXPATH-Grab IE DOM objects by XPATH IEscriptRecord-Makings of an IE script recorder ExcelFromXML-Create Excel docs without excel installed GetAllWindowControls-Output all control data on a given window.

Both are IE 11.

$oIE definitely starts pointing to some other thing rather than IE instance. Question is why this happens (what is a reason). As on workstation this is perfectly working code.

Alas, a long Google didn't help.

I'm stuck and have no ideas currently about what else can be done.

No doubt:

It may be that IE object point to another page or is not an abject at all. There are several reasons for the call to fail:

_IELinkClickByText($oIE, "Стройматериалы")

You have to run it in SCITE and see the error and warnings output.
