title: WPD equivalent of WIA DeviceDlg
body: <p>I'm adding Windows Portable Devices (WPD) support to an app that currently uses Windows Image Acquisition (WIA). WIA provides a handy picture selection dialog via IWiaItem::DeviceDlg.</p>
  
  <p>I can't find a WPD equivalent. Is there one, and, if not, what is the preferred technique to allow users to select items? I don't have to write my own dialog, do I?</p>
