>>>Hi everybody,

You can add specific code to the button

... when button active the page
this.parent.Addobj(this.name+"effect","shapeYellow",this)
* shapeYellow bind it to the button ( move, anchor, .... )
* deactivate
this.parent.removeobject(this.name+"effect")

unfortunately the VFP OOP model is not very flexible,
and this code contaminates the Parent object because a button doesn't allow AddObject.
