title: OpenFileDialog: Select Multiple Files Using a Check Box
body: <p>Is there an option to make check boxes appear beside files when multiselecting files using an openfiledialog?</p>
  
  <p>I know that there is a Windows option to change this, but is there a way to temporarily change this for my specific openfiledialog?</p>
  
  <p>Or alternatively is there a way to change the Windows setting? I was thinking I could check to see if its already set to show the check boxes, and if it is I do nothing, otherwise I change it and when the dialog closes I change it back. </p>
