The following example demonstrates how to set up an InkCanvas to recognize application gestures.

' Add this code to the contstructor or OnLoaded method.
If (inkCanvas1.IsGestureRecognizerAvailable) Then

    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture

    Dim gestures() As ApplicationGesture = _
                        {ApplicationGesture.Down, _
                         ApplicationGesture.ArrowDown, _
                         ApplicationGesture.Circle}

    inkCanvas1.SetEnabledGestures(gestures)
End If


...


Sub inkCanvas1_Gesture(ByVal sender As Object, _
    ByVal e As InkCanvasGestureEventArgs) Handles inkCanvas1.Gesture

    Dim gestureResults As ReadOnlyCollection(Of GestureRecognitionResult)
    gestureResults = e.GetGestureRecognitionResults()

    ' Check the first recognition result for a gesture.
    If gestureResults(0).RecognitionConfidence = _
       RecognitionConfidence.Strong Then

        Select Case gestureResults(0).ApplicationGesture
            Case ApplicationGesture.Down
                ' Do something.
            Case ApplicationGesture.ArrowDown
                ' Do something.
            Case ApplicationGesture.Circle
                ' Do something.
        End Select

    End If

End Sub 'inkCanvas1_Gesture
