Something to get you started. That just reads the current setting.

You can root around in the DOM methods on MSDN (I never did find it) or just use ControlSend():

WinActivate("[CLASS:IEFrame; TITLE:Google]", "")

ControlSend("[CLASS:IEFrame; TITLE:Google]", "", "[CLASS:Internet Explorer_Server; INSTANCE:1]", "^{+}")
Sleep(500)
ControlSend("[CLASS:IEFrame; TITLE:Google]", "", "[CLASS:Internet Explorer_Server; INSTANCE:1]", "^{+}")
Sleep(2000)

ControlSend("[CLASS:IEFrame; TITLE:Google]", "", "[CLASS:Internet Explorer_Server; INSTANCE:1]", "^{-}")
Sleep(500)
ControlSend("[CLASS:IEFrame; TITLE:Google]", "", "[CLASS:Internet Explorer_Server; INSTANCE:1]", "^{-}")

Edit: Clarity.

And for set the zoom of an internet obj created with the function _IECreateEmbedded?

[PsaltyDS]

It's still the same in most respects as a full instance of IE.

[Sbarabau]

Can you give me an example? I tried, but the zoom does not change with the obj created with _IECreateEmbedded...

There is no zoom in an IE ActiveX control (embedded) instance, even when done manually. So as far as I know you're out of luck.

Exactly as with the full IE instance, XDPI and YDPI are there for read-only reference, though:

$oIE = _IECreateEmbedded ()
GUICreate("Embedded Web control Test", 640, 580, _

        $WS_OVERLAPPEDWINDOW + $WS_VISIBLE + $WS_CLIPSIBLINGS + $WS_CLIPCHILDREN)
$GUIActiveX = GUICtrlCreateObj($oIE, 10, 40, 600, 360)
$GUI_Button_Back = GUICtrlCreateButton("Back", 10, 420, 100, 30)
$GUI_Button_Forward = GUICtrlCreateButton("Forward", 120, 420, 100, 30)
$GUI_Button_Home = GUICtrlCreateButton("Home", 230, 420, 100, 30)
$GUI_Button_Stop = GUICtrlCreateButton("Stop", 340, 420, 100, 30)

$iLogicalXDPI = $oScreen.logicalXDPI
$iLogicalYDPI = $oScreen.logicalYDPI
$iXZoom = $iXDPI / $iLogicalXDPI * 100
$iYZoom = $iYDPI / $iLogicalYDPI * 100

ConsoleWrite("$iXDPI = " & $iXDPI & "; $iYDPI = " & $iYDPI & @LF)

But there's no way to send a check to the page embedded with the command:

ControlSend("[CLASS:IEFrame; TITLE:Google]", "", "[CLASS:Internet Explorer_Server; INSTANCE:1]", "^{+}")

?

You lost me. We were talking about zoom level, and now "...there's no way to send a check to the page embedded...".

What do you mean by "send a check"? The function you posted would be for a regular instance of IE, and would change the zoom level.

For an embedded instance, you would have to change the window ID to that of the parent window containing the embedded IE control, and the zoom level wouldn't change anyway because that functionality is not there in an embedded browser instance, as far as I can tell.
