l want set a SetParent in my WPF application,
but when l try to do that. it doesn’t work, l try it on the .net 8
the program where l want to set is calc.exe.

private void MainWindow_Loaded(object sender, RoutedEventArgs e)
   {
       Process process = Process.Start("calc.exe");
       // Find the handle of the external window
       IntPtr externalWindowHandle = process.MainWindowHandle;

       if (externalWindowHandle != null)
       {
           // Reparent the external window into the WPF application
           SetParent(externalWindowHandle, new WindowInteropHelper(this).Handle);
       }
       else
       {
           MessageBox.Show("External window not found.");
       }


   }

l am expecting the view of calc.exe appear inside my wpf view
