PPT: For Each Loop Doesn't Find All Shapes on a Slide (163532)

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.

RESOLUTION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. 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
