dynamic monitor application ，how to chang shape‘s text？for example ，a box’s text .

• Cast the shape to a suitable class that has a text property, e.g. Box, RectangleBase or CaptionedShape:
  Box box = (Box)shape;
  box.Text = "New Text";
• Use the ICaptionedShape interface that all shapes with text implement:
  ICaptionedShape captonedShape = (ICaptionedShape)shape;
  captionedShape.SetCaptionText(0, "New Text");
