Memory Leak?

[Arlen]

I think I have memory leak issue...

Every time I use _IENavigate() my Memory Ram goes up and never down.. I could reach 1gb just using this function. Which is weird..

#include <IE.au3>
#include <GUIConstantsEx.au3>
#RequireAdmin

Global $oIE = _IECreateEmbedded()
Global $Form1 = GUICreate("Form1", 920, 466, 502, 342)
GUICtrlCreateObj($oIE, 8, 72, 897, 370) ;IE OBJ
Local $Button1 = GUICtrlCreateButton("FETCH", 808, 8, 91, 57)
GUISetState(@SW_SHOW)
While 1
    Local $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            Fetch()
    EndSwitch
WEnd

Func Fetch()
For $i = 0 To 20
    _IENavigate($oIE, 'https://www.google.com/search?source=hp&ei=hzprXM_zN-zs_QbExry4CQ&q=sad&btnK=Google+Search&oq=&gs_l=psy-ab.3..35i39j0i67l9.2993.3926..4083...1.0..0.137.749.0j6......0....1..gws-wiz.....6.eVCDaXHQXYA')
Next
EndFunc

Wow that's nasty.  We probably need a way to free the memory stored in $oIE.  I sunk 40 minutes into this, different tests that didn't solve the issue.

Doesn't work:

expandcollapse popup

#include <IE.au3>
#include <GUIConstantsEx.au3>
#RequireAdmin

Global $oIE
Global $Form1
Global $Button1
Global $controlID
$Form1 = GUICreate("Form1", 920, 466, 502, 342)
While 1
    Local $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            Fetch("https://www.google.com/search?hl=en&authuser=0&ei=Km5rXPXULY2l_QbE2ICICw&q=tube+snake+boogy&oq=tube+snake+boogy&gs_l=psy-ab.3..0i13l10.59391.60854..61379...1.0..0.159.577.0j5......0....1..gws-wiz.SM0Ug2XoHUM")
    EndSwitch
WEnd

Func Fetch($URL)
    Form1Create()
    _IENavigate($oIE, $URL)
EndFunc

Func Form1Create()
    ;$Form1 = GUICreate("Form1", 920, 466, 502, 342)
    ;If IsObj($oIE) Then $oIE.quit; = 0;$oIE.quit
    $oIE = 0
    GUICtrlDelete($controlID)
    GUICtrlDelete($Button1)
    GUIDelete($Form1)
    $Form1 = GUICreate("Form1", 920, 466, 502, 342)
    $oIE = _IECreateEmbedded()
    $controlID = GUICtrlCreateObj($oIE, 8, 72, 897, 370) ;IE OBJ
    $Button1 = GUICtrlCreateButton("FETCH", 808, 8, 91, 57)
    GUISetState(@SW_SHOW)
EndFunc

 

Because_IECreateEmbedded() doesn't seem to have functions to IE.quit.  You could try using this Example code instead: https://www.autoitscript.com/forum/topic/99234-iecreate2/

Your code works for me. But no hope for Microsoft to fix this any time soon..

I notice that the Memory Leak is caused by the URL?

;This won't leak for me
$URL = 'https://www.google.com/search?hl=en&authuser=0&ei=Km5rXPXULY2l_QbE2ICICw&q=tube+snake+boogy&oq=tube+snake+boogy&gs_l=psy-ab.3..0i13l10.59391.60854..61379...1.0..0.159.577.0j5......0....1..gws-wiz.SM0Ug2XoHUM'

;But this one will always leak
$URL2= 'https://www.google.com/search?source=hp&ei=hzprXM_zN-zs_QbExry4CQ&q=sad&btnK=Google+Search&oq=&gs_l=psy-ab.3..35i39j0i67l9.2993.3926..4083...1.0..0.137.749.0j6......0....1..gws-wiz.....6.eVCDaXHQXYA'

Yes, from what I read, memory leak appears only on certain pages or with certain data.

I was still having a memory leak with my code.  I was only trying to show the methods I had tried using to remove leak.  Nothing worked for me.

I put too much time into it.  I think you should try to use the: iecreate2

[Xandy]

And free the memory before loading a new URL.  But there is no method I know to free the memory with: _IECreateEmbedded().  The help file claimed that deleting the GUI host would free the memory but in my example it does not.
