After conversion to VB Public Shared Event Idle(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly

Question

I have converted my Face Recognition App to VB and it is giving an error which I am unable to resolve...

 Public Sub initialise_capture()
    grabber = New Capture()
    grabber.QueryFrame()
    'Initialize the FrameGraber event
    If parrellelToolStripMenuItem.Checked Then
        Application.Idle += New EventHandler(AddressOf FrameGrabber_Parrellel)
    Else
        Application.Idle += New EventHandler(AddressOf FrameGrabber_Standard)
    End If
End Sub

In C# it working fine but in VB its not working. Please help me resolve this problem as I am novice to .NET
