Tabbing With 2 Embedded IE Windows (Part 2)

[user52]

continued from http://www.autoitscript.com/forum/index.php?showtopic=36890

here's a snippet of the code i'm using:

expandcollapse popup

#include <guiconstants.au3>
;~ #include <ie.au3>
#include <IET2.0.6.au3>

;~ ProcessClose("iexplore.exe")

HotKeySet("{ESC}", "_Exit")

$gui = GUICreate("", 700, 700, -1, -1, 0)
$Label_1 = GuiCtrlCreateLabel("", 10, 10, 670, 650)

_IEErrorHandlerRegister()

;setup ie win
    $oIE1 = _IECreate("about:blank",0,0,1,0)
    $oIE1.AddressBar = 0
    $oIE1.MenuBar = 0
    $oIE1.StatusBar = 0
    $oIE1.ToolBar = 0
    $uID1 = Random(1000, 100000000)
    $oIE1.document.title = $uID1
    WinWait($uID1, "", 7)
    $hoIE1 = WinGetHuID1)
    $pid1 = WinGetProcess($hoIE1)

    DllCall("user32.dll", "long", "SetWindowLong", "hwnd", $hoIE1, "int", -16, "long", $WS_POPUP)
    DllCall("user32.dll", "int", "SetParent", "hwnd", $hoIE1, "hwnd", $gui)
;move
    $pos = ControlGetPos($gui, "", $Label_1)
    If IsArray($pos) Then
        WinMove($hoIE1, "", $pos[0], $pos[1], $pos[2], $pos[3])
    EndIf
;show   
    GuiSetState()
    $oIE1.visible=1

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit

    Exit
EndFunc

Windows 2000/XP: When you change the parent of a window, you should synchronize the UISTATE of both windows. For more information, see WM_CHANGEUISTATE and WM_UPDATEUISTATE.

i was looking at the SetParent() function and was wondering how to synchronize the UISTATE of both windows.

thanks

I'm not sure what the value of $hwnd should be, but this is similar to the code you should probably be using to do this:

#include <misc.au3>

$WM_CHANGEUISTATE = 0x127
$WM_UPDATEUISTATE = 0x128

_SendMessage($hWnd, $WM_CHANGEUISTATE)
_SendMessage($hWnd, $WM_UPDATEUISTATE)

$hwnd should probably be replaced with the Gui handle, but I'm thinking it could be the IE control instead, or the containing shell object, or the containing document embedding object.

It would be cool if you get this working nicely. I've had some trouble embedding two+ IE objects. The problem is the last IE object to be added to the GUI steals all of the accelerator key events from the other IE objects, and the cursor focus. So you can't click on the first IE object and tab around, it just jumps to the second IE object and tabs there. Very frustrating, but I thought it was due to an internal AutoIt limitation. Some of my research into workarounds pointed to some kind of window message to indicate the currently active IE object, but I could never find it.

thank you lod3n

i finally got the ie windows not to take away the focus of the gui. it was just a matter of setting $WS_CHILD right after setting it's parent using "SetParent".

An application can use the SetParent function to set the parent window of a

pop-up, overlapped, or child window. The new parent window and the child

window must belong to the same application.

If the window identified by the hWndChild parameter is visible, the system

performs the appropriate redrawing and repainting.

For compatibility reasons, SetParent does not modify the WS_CHILD or

WS_POPUP window styles of the window whose parent is being changed.

Therefore, if hWndNewParent is NULL, you should also clear the WS_CHILD bit

and set the WS_POPUP style after calling SetParent. Conversely, if

hWndNewParent is not NULL and the window was previously a child of the

desktop, you should clear the WS_POPUP style and set the WS_CHILD style

before calling SetParent.

Windows 2000 or later: When you change the parent of a window, you should

synchronize the UISTATE of both windows. For more information, see

WM_CHANGEUISTATE and WM_UPDATEUISTATE.

Looks like I wrote something similar to this already:

Nice to see I'm not the only one having the problem.

Nice solution, however I only understand half of your code for getting this Tab-problem working and my problem is slightly different. I want to attach one IE window on each of two tabs.

Here is the code im currently using. Is it possible to realize that?

#include <guiconstants.au3>
#include <IE.au3>
$oIE1 = _IECreateEmbedded()
$oIE2 = _IECreateEmbedded()

$main_window = GUICreate("Testwindow", @DesktopWidth/2, @DesktopHeight/2, 0, 0, $WS_CAPTION + $WS_SYSMENU + $WS_MAXIMIZEBOX + $WS_MINIMIZEBOX + $WS_VISIBLE + $WS_CLIPSIBLINGS)
GUISetState(@SW_MAXIMIZE, $main_window)
$mainpos_array = WinGetPos($main_window)
$main_tab = GUICtrlCreateTab(10, 10, 90, 50)
$main_tab1 = GUICtrlCreateTabItem("Tab1")
$GUIoIE1 = GUICtrlCreateObj($oIE1, 10, 30, $mainpos_array[2] - 30, $mainpos_array[3] - 125)
GUICtrlCreateTabItem("")
$main_tab2 = GUICtrlCreateTabItem("Tab2")
$GUI_oIE2 = GUICtrlCreateObj($oIE2, 10, 30, $mainpos_array[2] - 30, $mainpos_array[3] - 125)
GUICtrlCreateTabItem("")
GUICtrlSetState($main_tab1, $GUI_SHOW)
GuiSetState()

_IENavigate($oIE2, "http://images.google.com/", 0)

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            GUIDelete()

WEnd
