title: Hosting a flash app in a WindowsFormsHost in a Surface application and .CallFunction
body: <p>I'm working on adding a Flash app to a Surface application. It looks to be working just fine (overlaying the Flash app with an almost transparent Surface window to catch the Contacts).</p>
  
  <p>However, if I want to call a Flash function in my SWF (using .CallFunction), I get a E_FAIL exception. It is suggested that a callback function in the SWF might be missing for the defined function, but, although I can't check since the SWF isn't mine, I think that's not the case.</p>
  
  <p>Does anybody have a suggestion why these E_FAIL exceptions might happen?</p>
  
  <p>Thanks,</p>
  
  <p>Bart</p>
