PaintMaxPasses example for Visual Basic
Note: Also works with Access 95 and 97.
This example includes two procedures. First, a button click starts a multi-pass paint effect; then LEAD's PaintNotification event changes the direction of the effect on each pass.
Private Sub StartEffect_Click()
Lead1.AutoRepaint = False
Lead1.PaintEffect = EFX_EFFECT_WIPE_L_TO_R 'Set the Effect
Lead1.PaintMaxPasses = 5 '5 total passes
Lead1.PaintPass = 1 'Start with pass number 1
Lead1.PaintNotificationDelay = 200 ' Delay 200 milliseconds between passes
Lead1.Load "c:\lead\images\image1.cmp", 0, 0, 1 'Load the image
Lead1.AutoRepaint = True
End Sub
Private Sub Lead1_PaintNotification(ByVal uPass As Integer, ByVal uType As Integer)
'If the first pass is complete
If ((uType = EFX_NOTIFY_IMAGE) And (uPass > 0)) Then
'Toggle the effect from left_to_right to right_to_left
If Lead1.PaintEffect = EFX_EFFECT_WIPE_L_TO_R Then
Lead1.PaintEffect = EFX_EFFECT_WIPE_R_TO_L
Else
Lead1.PaintEffect = EFX_EFFECT_WIPE_L_TO_R
End If
End If
End Sub
