SetParent

[JohnOne]

I'm having an issue trying to set an IE window's parent similar as in >this post, I thought it would be pretty simple to be honest but the IE window does not appear to be set as child to my GUI.

I get no errors either, can anyone spot my mistake?

//Create an Internet Explorer kiosk window
    //hWnd is my gui
    HINSTANCE IEKIOSK = ShellExecuteA(hWnd, "open",
        "C:\\progra~1\\intern~1\\iexplore.exe",
        "-k http://www.google.com",
        "",
        SW_SHOW);

    HWND IEWIN = NULL;

    do{IEWIN = FindWindowA("IEFrame", "http://www.google.com/ - Google - Windows Internet Explorer");
    Sleep(100);
    }while(! IEWIN);
    Beep(700,100);
    
    if(! SetParent(IEWIN,hWnd)){
        MessageBoxA(NULL, "Funtion failure", "Error", MB_OK);
    };
        
    MoveWindow(IEWIN,0,0,400,300,true);

Hi,

Do you want it in autoit? if so, try this :

#include <GUIConstantsEx.au3>
#include <Constants.au3>
#include <WinAPI.au3>

Opt("WinTitleMatchMode", 2)

;Create an Internet Explorer kiosk window
ShellExecute("C:\\progra~1\\intern~1\\iexplore.exe", "-k http://www.google.com")

Local $hIEWIN = 0

Do
    $hIEWIN = WinGetHandle("[CLASS:IEFrame;TITLE: - Google - Windows Internet Explorer]")
    Sleep(100)
Until $hIEWIN > 0

Beep(700, 100)

Local $hGUI = GUICreate("MyGUI")
GUISetState(@SW_SHOW, $hGUI)

If _WinAPI_SetParent($hIEWIN, $hGUI) = 0 Then
    MsgBox($MB_OK, "Funtion failure", "Error")
EndIf

;~ WinMove($hIEWIN, 0, 0, 400, 300)

While GUIGetMsg() <> $GUI_EVENT_CLOSE
    Sleep(10)
WEnd

Edit: Added indents.

Br, FireFox.

Thanks FireFox, but my problem is that, when I convert that code to C++ it does not work.

Or perhaps more specifically, the IE window does not pseudo embed into the window I create in c++ (hWnd).

The _WinAPI_SetParent() is basically just a DllCall to C++ Setparent and my expectations were that it would do exactly the same as what it does in AutoIt.

It seems very odd that it does not.

EDIT:

I have used a few different ways of starting IE, including CoCreateInstance, CreateProcess, ShellExecuteEx and simply retrieving the handle of an already running IE window. All without success.

Can you send me your project in a packed file?

[JohnOne]

Certainly, but it's part of a larger project so I'll just make a new one with the necessary code.

Give me a few minutes.

[JohnOne]

Here is project

http://www.filedropper.com/ieembed

EDIT: not quite a few minutes, but had a pop in from a pal in the middle, so I had to stop cause he was mocking me for being a big daft science cowboy.

EDIT2: I could not be bothered to put a button in so I just shamefully recycled the exit from file menu to run the function

The ShellExecute fails and it avoids the MessageBox to be displayed, I can see that with breakpoints.

You can't get a partial title with the FindWindow function, you will need to use the EnumWindows function and check the titles (which I can't get to work).

I have tested directly with the handle of the IE kiosk window and the rest of the script is OK.

I don't code in C++, I will be glad if someone points out what's wrong :

expandcollapse popup

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam);
void myFunc1(HWND);

void Embed(){
    /*
    HINSTANCE IEKIOSK = ShellExecute(
            hWnd, 
            L"open", 
            L"C:\\Progra~1\Intern~1\\iexplore.exe",
            L"-k http://www.google.com/",
            L"",
            SW_SHOW);
    //??does not work
    if (!IEKIOSK) {
        MessageBox(NULL, L"Function ShellExecute Failed", L"Boooooo!", MB_OK);
        exit(0);
    }
    */
    EnumWindows(EnumWindowsProc, NULL);
}

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
    LPTSTR title = (LPTSTR)""; LPTSTR class_name = (LPTSTR)"";

    GetClassName(hwnd, class_name, sizeof(class_name));
    GetWindowText(hwnd, title, sizeof(title));

    printf("%d", lstrcmpi(class_name, (LPTSTR)"IEFrame")); //??access violation

    //if(lstrcmpi(class_name, (LPTSTR)"IEFrame") && lstrcmpi(title, (LPTSTR)"Google - Windows Internet Explorer")) {
    if((int)hwnd==0x002003D8) { //handle of the IE kiosk wnd
        myFunc1(hwnd);
        return FALSE;
    }

    return TRUE;
}

void myFunc1(HWND wnd) {
    Beep(700,150);

    if (!SetParent(wnd, hWnd)){
        MessageBox(NULL, L"Function Setparent Failed", L"Boooooo!", MB_OK);
    }

    MoveWindow(wnd, 0, 0, 400, 400, TRUE);
}

Br, FireFox.

Sorry, I already had a normal IE window open just for testing and Findwindow was working fine to get window handle.

The Shellexecute was not working because I left out an escaping backslash in the path somehow.

Are you saying that the IE window embeds into the created window for you?

[FireFox]

Are you saying that the IE window embeds into the created window for you?

Yes. Try without the MoveWindow function.

[JohnOne]

Weird, Does not embed for me, I've tried rebooting on a number of occasions, and on two different computers 

[FireFox]

Well, I edited a few lines in the IEEMBED file. I don't know if it affects the rest of the program.

Try it: http://www.mediafire.com/download/rlcnzm4dv7apqwk/IEEMBED.zip

[JohnOne]

Is that different from what you posted above, because I tried that?

[JohnOne]

FireFox. Thank you kindly. Your code works, but I can not immediately see what you have changed other than where you call the function.

Can you give an explanation if you have the time?

[FireFox]

I removed the local declaration of hWnd in the InitInstance function, otherwise it overrides? the global one which is then not set.

Well spotted and thanks again, been cracking me up for a couple of days now.

[FireFox]

You're welcome

Last week I'm also having the same problem. In this answer useful for me.I will  try  to  use the same method the error is to be clear.
