The following example uses three image controls to animate a butterfly image across a form. The Hidden1 image control contains a picture of a butterfly with its wings up and the Hidden2 image control contains a picture of the same butterfly with its wings down. Both image controls have their Visible property set to False (0). The TimerInterval property is set to 200. Each time the Timer event occurs, the picture in the image control Visible1 is changed by using the PictureData property of the hidden image controls, and the visible image control is moved 200 twips to the right. The visible image control is moved back to the left side of the form when its Left property value is greater than the width of the form stored in the public variable gfrmWidth. The value of gfrmWidth is set to Me.Width in the form's open event.
Private Sub Form_Timer()
Static intPic As Integer
Select Case intPic
Case Is = 1
Me!Visible1.PictureData = Me!Hidden1.PictureData
Case Is = 2
Me!Visible1.PictureData = Me!Hidden2.PictureData
Case Else
End Select
If intPic = 2 Then intPic = 0
intPic = intPic + 1
If (Me!Visible1.Left > gfrmWidth) Then Me!Visible1.Left = 0
Me!Visible1.Left = Me!Visible1.Left + 200
End Sub
