        Process PR = Process.Start(psi);

        // true if the associated process has reached an idle state:
        PR.WaitForInputIdle(); 

        //System.Threading.Thread.Sleep(3000);

        IntPtr hwd = PR.MainWindowHandle;

        // loading exe to the wpf window:
        SetParent(PR.MainWindowHandle, _pnlSched.Handle);  

    }
    catch (Exception ex)
    { 
        //Nothing...
    }
  }
}

Have you checked out Window Style to make notepad borderless (if you wish), and also tried setting notepad's main window's state to maximized? — Warty, Dec 08 '13 at 21:34

Would the following sites help you...http://stackoverflow.com/questions/4743213/application-that-can-open-program-in-full-screen or http://stackoverflow.com/questions/14799691/wpf-maximizing-borderless-window-by-taking-in-account-the-user-taskbar — bucketblast, Dec 08 '13 at 21:49
See GetWindowLong and SetWindowLong (you'll have to p/invoke). As for resizing the inner window, you might have to do that in your Form's resize events - I want to say that WinAPI doesn't natively support Dock = Fill, though it's been too long for me to remember. — Warty, Dec 08 '13 at 21:50

Using System.Diagnostics

ProcessStartInfo strtInf = new ProcessStartInfo("notepad.exe");
strtInf.WindowStyle = ProcessWindowStyle.Maximized;
Process.Start(strtInf);

If you want that the file open with

You add this just after

strtInf.Arguments = "E:\\Tableaux\\atelier.sql";
Process.Start(strtInf);
