PPT2000: For Each Loop Doesn't Find All Shapes on a Slide (222734)

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.

For additional information, click the following article number to view the article in the Microsoft Knowledge Base: As the following sample Visual Basic procedure demonstrates, you can replace the For Each...Next statement with a Do...Loop statement (including While) 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
