>I have a screen that contains a page frame. Depending on the data that is read, the page frame adjusts the number of pages it contains (pagecount). When a new page is added I would like to add some code to the activate method of the page. How do I do this inside a program on the fly. TIA

You can't add code on the fly, but you could use a sub-classed page that will have that code added.
