Question

Here is my code: I create a shape in a slide powerpoint. Microsoft.Office.Interop.PowerPoint.Shape rectangle = curSlide.Shapes.AddShape(Microsoft.Office.Core.MsoAutoShapeType.msoShapeRoundedRectangle slideWidth - 110 slideHeight - 60 100 50); Sequence objSequence = curSlide.TimeLine.InteractiveSequences.Add(1); Effect pEffect_start = objSequence.AddEffect(rectangle MsoAnimEffect.msoAnimEffectTransparency MsoAnimateByLevel.msoAnimateLevelNone MsoAnimTriggerType.msoAnimTriggerOnShapeClick 1); I can add an animation to shape but with a sound I can not. I want add a sound in this shape when animation run so the sound is play. How can I do that?
