how can I center a zoom on a clicked location?  I know this has been asked before.  But I didn't see a good answer for it.  I am using VB for developing.  I am capturing the x,y coordinates in the mouse down event and trying to use them to center the image.  Any help out there?

Please add the following code lines to your project to be able to  zoom on a clicked location:

Private Sub LEAD1_MouseDown (Button As Integer, Shift As Integer, x As Single, y As Single)

LEAD1.ScaleMode = 3
Dim xPixels, yPixels, newWidth, newHeight
xPixels = x / Screen.TwipsPerPixelX
yPixels = y / Screen.TwipsPerPixelY
newWidth = LEAD1.ScaleWidth - 60
newHeight = LEAD1.ScaleHeight - 60
LEAD1.ZoomToRect xPixels - newWidth / 2, yPixels - newHeight / 2, newWidth, newHeight

End Sub
