SYMPTOMS
========

When you use a For Each...Next statement to loop through and remove all shapes
on a specified slide, some shapes are not deleted. For example, the following
code does not delete all the shapes on a slide.

     For Each shapeObject In ActivePresentation.Slides(1).Shapes
   
        shapeObject.Delete
   
     Next shapeObject

CAUSE
=====

When you use a For Each...Next statement in a Microsoft Visual Basic for
Applications procedure, the procedure keeps track of each shape that it finds.
When it finds the first shape, it knows that the next shape is the second shape
on the slide. However, when it finds the first shape and then deletes it, the
next shape becomes the first shape on the slide. Consequently, each subsequent
shape on the slide is assigned a new position.

As the following sample Visual Basic procedure demonstrates, you can replace the
For Each...Next statement with a Do...Loop statement (including the While
keyword) to remove all the shapes on a slide.

     Sub DeleteAllShapes()

        ' Delete every shape on slide 1.
        With ActivePresentation.Slides(1)
           While (.Shapes.Count > 0)
              .Shapes(1).Delete
           Wend
        End With

     End Sub
