Public _form As CaptureCtrlForm = New CaptureCtrlForm()
Public Sub CurrentExample()
   ' reference the capture control
   Dim capturectrl As CaptureCtrl = _form.CaptureCtrl

   ' select a video device, use your device name here instead of USB
   If capturectrl.VideoDevices("Analog") Is Nothing Then
      Throw New Exception("No Analog video device available")
   End If

   capturectrl.VideoDevices("Analog").Selected = True

   ' get the video capture subtypes collection
   Dim subtypes As CaptureSubTypes = capturectrl.VideoCaptureSubTypes

   Try
      ' loop through all video subtypes
      For Each cs As CaptureSubType In subtypes
         ' set the result to what we expect
         _result = (cs Is subtypes.Current)
      Next cs
   Catch e1 As Exception
      _result = False
   End Try

   ' we'll loop on the state and pump messages for this example.
   ' but you should not need to if running from a Windows Forms application.
   Do While capturectrl.State = CaptureState.Running
      Application.DoEvents()
   Loop
End Sub
C#Copy Code
public bool _result = false;
