Setting WPF Dialog owner from within WinForms application

I had some WPF dialog that I need to show from older WinForms application, or more precisely from some WinForms UserControl. The problem was to set Owner of that dialog, GetWindow() didn’t work (of course) and leaving dialog without an owner, made it possible to disappear when user switch from application to application. And I didn’t want to show it in task bar either.

Thankfully, there is a very easy way, which, for some reason, I didn’t find quite fast – use WindowInteropHelper class. Here is an example:

   1: MyWpfDialog dialog = new MyWpfDialog();
   2:  
   3: //remember, this is WinForms UserControl and its Handle property is
   4: //actually IntPtr containing Win32 HWND.
   5: new System.Windows.Interop.WindowInteropHelper(dialog).Owner = this.Handle;
   6: dialog.ShowDialog();
