    Probably little bit strabeg question:

    Is it possible to run some external WinForms exe in DocumentWindow?

    Thank you.

    Hi Oleg,

    Thank you for contacting us.

    It appears that this is possible and you just need to use some methods from user32.dll. For example:
    private void radButton1_Click(object sender, EventArgs e)
        DocumentWindow document = new DocumentWindow();
        document.Text = "New Document";
        Process p = Process.Start("notepad.exe");          
        Thread.Sleep(500); //time is needed for the process starting
        SetParent(p.MainWindowHandle, document.Handle);
        SetWindowLong(p.MainWindowHandle, GWL_STYLE, WS_VISIBLE);         
        MoveWindow(p.MainWindowHandle, 0, 0, document.Width, this.Height, true);
    [DllImport("usesome r32.dll")]
    static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
    [DllImport("user32.dll", SetLastError = true)]
    private static extern bool MoveWindow(IntPtr hwnd, int x, int y, int cx, int cy, bool repaint);
    [DllImport("user32.dll", EntryPoint = "SetWindowLongA", SetLastError = true, CallingConvention = CallingConvention.Cdecl)]
    private static extern long SetWindowLong(IntPtr hwnd, int nIndex, long dwNewLong);
    private const int GWL_STYLE = (-16);
    private const int WS_VISIBLE = 0x10000000;

    Please let me know if there is something else I can help you with.
