Sample Visual Basic Procedure
-----------------------------
Sub CenterShape()
' Object reference to a shape.
Dim ShapeObject As Shape
' Holds the center of the slide.
Dim SlideCenter As Long
' Holds the center of a shape.
Dim ShapeCenter As Long
' Stores the number of shapes.
Dim lNumberOfShapes As Long
' Variable to store the selection type.
Dim lSelectionType As Long
' Variables used to build the error message.
Dim ErrorMessage As String
Dim ErrorWindowTitle As String
' Variables used to build the success message.
Dim Message As String
Dim WindowTitle As String
' Holds the number of shapes centered.
Dim count As Long
' Stores the selection type.
lSelectionType = ActiveWindow.Selection.Type
' Checks whether selection is a shape.
If lSelectionType <> ppSelectionShapes Then
Select Case lSelectionType
' The selected item is a slide.
Case ppSelectionSlides
ErrorMessage = "You have a slide selected. "
ErrorWindowTitle = "Slide Selected"
' The selected item is text.
Case ppSelectionText
ErrorMessage = "You have text selected. "
ErrorWindowTitle = "Text Selected"
' Nothing is selected.
Case ppSelectionNone
ErrorMessage = "You have nothing selected. "
ErrorWindowTitle = "Nothing Selected"
Case Else
ErrorMessage = "A problem with you selection. "
ErrorWindowTitle = "Unkown Error"
End Select
' Build the rest of the error message.
ErrorMessage = ErrorMessage & "Please select a " _
& "shape and run the macro again."
' Display the error message.
MsgBox ErrorMessage, vbExclamation, ErrorWindowTitle
' Stop the macro.
End
End If
' Calculates the center of the slide.
SlideCenter = ActivePresentation.PageSetup.SlideWidth \ 2
' Initializes the count before using it.
count = 0
' Centers each object as the loop goes through.
For Each ShapeObject In ActiveWindow.Selection.ShapeRange
ShapeCenter = ShapeObject.Width \ 2
ShapeObject.Left = SlideCenter - ShapeCenter
count = count + 1
Next ShapeObject
' Builds the success message.
WindowTitle = "Macro Completed"
Message = "Successfully centered "
If count = 1 Then
Message = Message & "1 object."
Else
Message = Message & count & " "
Message = Message & "objects"
End If
' Displays the message box.
MsgBox Message, vbInformation, WindowTitle
End Sub
