Embed an application within a WPF Window

I'm working in Visual Studio 2015, in C # and WPF technology. I need to embed to a window of my program, another window system of a third party system, such as Notepad.

I found the answer here (sorry the site is in spanish) but it only works with Windows Form.

This is my code.

//get the third party window
public static IntPtr getWindow(string titleName)
{
   Process[] pros = Process.GetProcesses(".");
   foreach (Process p in pros)
      if (p.MainWindowTitle.ToUpper().Contains(titleName.ToUpper()))
         return p.MainWindowHandle;
      return new IntPtr();
}

//Get my own window
IntPtr ptr = new WindowInteropHelper(this).Handle;

//a window embedded within the other
[DllImport("user32.dll")]
        public extern static IntPtr SetParent(IntPtr hWnChild, IntPtr hWndNewParent);

As I said, that works for Windows Forms, but in WPF doesn't work.

Here is the code, the problem was that you need to set position, width, height and repaint the child window in the new parent window.

public void CapturarApp()
        {
            hWndApp = ScreenFuntion.getWindow("Notepad");
            if (hWndApp.ToInt32() > 0)
            {
                ProgramsEncrustForm.MoveWindow(hWndApp,
                    0, 0,
                    Int32.Parse(Width.ToString()),
                    Int32.Parse(Height.ToString()), 1);
                ProgramsEncrustForm.SetParent(hWndApp, new WindowInteropHelper(this).Handle);
            }
            else
            {
                hWndApp = IntPtr.Zero;
            }
            this.Show();
        }

And here is the method to move and repaint the window

[System.Runtime.InteropServices.DllImport("user32.dll")]
public extern static int MoveWindow(IntPtr hWnd, int x, int y,
    int nWidth, int nHeight, int bRepaint);
