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

Iím using ImageAnimator class with a GIF animation that was designed with Animation Shop 3 to play or loop only once. When using the code below the animation starts looping repeatedly.

Does anyone know the right code to play this GIF animation one time only?

Thanks

Andy

This is the code Iím using:
Code:
'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
