What This VBA Code Does

This code allows you to lock and unlock the Aspect Ratio of a shape or picture in PowerPoint.  This can come in handy when you are resizing an image and you want to keep the same dimension ratio to prevent your image from looking disproportionate.

  'By Object Name (Turn off Lock)
    ShapeName = "Title 1"
    ActiveWindow.Selection.ShapeRange(ShapeName).LockAspectRatio = msoCFalse
On Error GoTo 0

Exit Sub

Select_Object:
  MsgBox "No object is selected"
  Exit Sub
