title: Capture event for fingerprint reader in no active application
body: <p>I have an application that validates users through a fingerprint reader. The validation is done in a method that i subscribed to manage the event, it looks like this.</p>
  
  <p>FingerprintVerificationControl.OnComplete+=new DPFP.Gui.Verification.VerificationControl._OnComplete(FingerprintVerificationControl_OnComplete);</p>
  
  <p>Everything goes well while i'm woriking with the application, i mean, when it has the focus, but, i have put it in the system tray using a notifyicon control and associating it with a contextmenu control to restore and close the app; so when it is in the system tray (is not the active application) i have no response from the fingerprint to manage the validation; the event of read the finger of the user does not fires.</p>
  
  <p>My question is, what is the best way to manage that? Is it possible?. I found that i can do it if i make a windows service, other sites say that with Win32 API, others have examples but with keyboard events like presss key and so on. Any idea? any idea would be thank.</p>
