Does anyone know how to play a GIF animation only once?

'Create a Bitmpap Object.
    Private WaterDropAnimation As New Bitmap("WaterDrop.gif")
    Private currentlyAnimating As Boolean = False

    'This method begins the animation.
    Public Sub AnimateImage()
        If Not currentlyAnimating Then
            'Begin the animation only once.
            ImageAnimator.Animate(WaterDropAnimation, New EventHandler(AddressOf Me.OnFrameChanged))
            currentlyAnimating = True
        End If
    End Sub

    Private Sub OnFrameChanged(ByVal o As Object, ByVal e As EventArgs)
        'Force a call to the Paint event handler.
        Me.Invalidate()
    End Sub

    Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)


        'Get the next frame ready for rendering.
        ImageAnimator.UpdateFrames()
        'WaterDropAnimation.MakeTransparent(WaterDropAnimation.GetPixel(0, 0))
        'Draw the next frame in the animation.
        e.Graphics.DrawImage(Me.WaterDropAnimation, New Point(125, 125))

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        'Begin the animation.
        AnimateImage()
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        If currentlyAnimating Then
            'Begin the animation only once.
            ImageAnimator.StopAnimate(WaterDropAnimation, New EventHandler(AddressOf Me.OnFrameChanged))
            currentlyAnimating = False
        End If
    End Sub
