Version Added: Word 2007
expression An expression that returns a Shape object.
Use this property with the RelativeVerticalSize property. When set to wdShapeSizeRelativeNone (-999999) (see the WdShapeSizeRelative enumeration), this property should be ignored because the shape does not use percent sizing. The height is solely determined by the Height property.
