SUMMARY
This article contains a sample Microsoft Visual Basic for Applications macro (Sub procedure) that finds all objects in the active presentation and applies an entry custom animation to each one. The macro randomly chooses which animation effect to apply to each object.

Dim SlideObject As Slide Dim ShapeObject As Shape Dim HoldRandomValue As Byte Dim EffectList(1 To NumEffects) As Long Dim TotalChanges As Long

' Used for error trapping. On Error Resume Next Err.Clear

' Initialize the counters. TotalChanges = 0

' Set up the Effect list. SetUpEffectList EffectList

' Outer loop goes through every slide in the Active presentation. For Each SlideObject In Application.ActivePresentation.Slides

' Inner loop goes through every shape in the presentation. For Each ShapeObject In SlideObject.Shapes

With ShapeObject.AnimationSettings

' This property must be set to True for any of the ' other properties of the AnimationSettings object ' to take effect. .Animate = msoTrue

' Assign a random animation to the object. Randomize HoldRandomValue = Int((NumEffects * Rnd) + 1)

' Assign a random animatation to the object. .EntryEffect = EffectList(HoldRandomValue) If Err.Number <> 0 Then MsgBox "An error occured. Try runnning the macro " _ & "again.", vbCritical, "Error" End If

' Increment the object count. TotalChanges = TotalChanges + 1 End With

Next ShapeObject

Next SlideObject

' See whether any objects were changed. If TotalChanges = 0 Then MsgBox "No objects available. No changes were made " _ & "to the presentation.", vbInformation, "No Objects" Else

' Set up the message box. If TotalChanges = 1 Then MsgBox "One object was given a random custom animation.", _ vbInformation, "Random Custom Animation" Else MsgBox "Suscessfully applied a custom animation to all " _ & "objects.", vbInformation, TotalChanges _ & " Objects Animated" End If
