_IEcreateEmbedded source problem...

[Brickoneer]

Hey guys, I've got yet another question. I searched around and can't seem to find anyone else with the same problem. Basically, I have an embedded IE object, I have it navigate to a page, and want to read the source. When I try and read the source, IE.au3 gives me an error.

Here is a reproducer:

#include <IE.au3>
#include <String.au3>
#include <GUIConstants.au3>

$hwnd = GUICreate("test", 500, 500, -1, -1, -1)
Opt("GUIOnEventMode", 1)
$oIE = _IECreateEmbedded()
GUICtrlCreateObj($oIE, 10, 30, 500 - 20, 500 - 40)
GUISetState()
_IENavigate($oIE, "about:blank")
Sleep(1000)
_IEDocWriteHTML($oIE, '<frameset id=mainset cols="10,10">' _
         & '<frame name=frame1 src="http://www.google.com">' _
         & '<frame name=frame2 src="http://www.google.com">')
_IEAction($oIE, "refresh")
Global $Frame = _IEFrameGetObjByName($oIE, "frame1")
$framesrc = _IEDocReadHTML($Frame) ;This seems to be the line that makes the error.
While 1
    Sleep(1000)
WEnd

The error is:

CODE

C:\PROGRA~1\AutoIt3\Include\IE.au3 (2214) : ==> The requested action with this object has failed.:

Return $o_object.document.documentElement.outerHTML

Return $o_object.document^ ERROR

Is there no .outerHTML in a embedded IE? what am I doing wrong?

Many thanks!

Use _IEErrorHandlerRegister() -- you should see an Access is denied error at the console.

This is a cross-site frame secuity restriction. You cannot access the google frame from script because its parent frame is not on google.com

Sorry, this is one of the areas where making the browser object secure from hackers limits its functionality.

I ran into this problem myself. Dale is correct on this one.

Thanks for the very informative reply!

I assume you mean it is seeing the GUI as a parent frame, and triggering the cross-site security restrictions?

Is there any way around this? If not, doesn't that mean an embedded IE browser using frames is almost impossible to automate/manipulate?

many thanks,

No, it's seeing the frameset of your local HTML as the parent. Your local HTML/frameset is not from google, so putting google frames inside it makes it cross-site.

Simply create two embedded browser objects and they will very scriptable:

#include <IE.au3>
#include <String.au3>
#include <GUIConstants.au3>

$hwnd = GUICreate("test", 600, 500, -1, -1, -1)
Opt("GUIOnEventMode", 1)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Quit")
$oIE_1 = _IECreateEmbedded()
$oIE_2 = _IECreateEmbedded()
GUICtrlCreateObj($oIE_1, 10, 10, 285, 480)
GUICtrlCreateObj($oIE_2, 305, 10, 285, 480)
GUISetState()
_IENavigate($oIE_1, "http://www.autoitscript.com", 0)
_IENavigate($oIE_2, "http://www.google.com", 1)
ConsoleWrite(_IEDocReadHTML($oIE_2) & @LF)

While 1
    Sleep(20)
WEnd

Func _Quit()
    Exit
EndFunc
