>I don't think so, because once you start the Designer, you wrapper would have finished. You'd need some kind of event handler for when the designer closed.

no you don't, as I already said: we can set obj.DesignMode=.t. as default value and in Init() this.Designmode=.f., as the Init() only runs at runtime.

This led me to the solution of that partial problem, so was helpful, thanks!
