_IE_Wait_notCpuMemoryChanges() and _IE_GetPid() - as suplement for _IELoadWait()

1 post in this topic

#1 ·  Posted (edited)

From _IELoadWait() doc:

Browser scripting security restrictions may sometimes prevent _IELoadWait() from guaranteeing that a page is fully loaded and can occasionally result in untrapped errors.

In these cases you may need to avoid calling _IELoadWait() and attempt to employ other methods of insuring that the page load has completed.
These methods might include using a Sleep command, examining browser status bar text and other methods.


I would like to present an additional method.

#include <IE.au3>


Func _Example()
    Local $oIE = _IECreate("")
    Send("{TAB 12}")
    _IE_Wait_notCpuMemoryChanges($oIE, 10)
EndFunc   ;==>_Example

Func _IE_Wait_notCpuMemoryChanges(ByRef $oIE, $iSleep = 0)
    If IsObj($oIE) Then
        Local $iIEPID = _IE_GetPid($oIE)
        Local Static $iWorkingSetSize
        Local Static $iPeakWorkingSetSize
        Local $aMemory
        While 1
            $aMemory = ProcessGetStats($iIEPID)
            If UBound($aMemory) Then
                If $iWorkingSetSize <> $aMemory[0] Or $iPeakWorkingSetSize <> $aMemory[1] Then
                    $iWorkingSetSize = $aMemory[0]
                    $iPeakWorkingSetSize = $aMemory[1]
                    If $iSleep <> 0 Then Sleep($iSleep)
EndFunc   ;==>_IE_Wait_notCpuMemoryChanges

Func _IE_GetPid(ByRef $oIE)
    Local $hwnd = _IEPropertyGet($oIE, 'hwnd')
    Local $PID = DllStructCreate("int")
    Local $aCall = DllCall("user32.dll", "int", "GetWindowThreadProcessId", "hwnd", HWnd($hwnd), "dword*", DllStructGetPtr($PID))
;~  MsgBox(0, "PID", $aCall[2])
    Return $aCall[2]
EndFunc   ;==>_IE_GetPid
