I don't use the code to prevent moving to different pages (I did in other projects, but don't have the code for that available). I use it to dynamically refresh labels and other controls to different contents when the page switches. Nothing spectacular, so nothing really to post. Here's a simple example:

* pageframe init
*
* use this for uienabler class (code in refresh method)
*
LOCAL oPage
FOR EACH oPage IN this.Pages
  oPage.NewObject("uienabler","uienabler","mylibrary")		&& uienabler causes refresh of page when pages switched
ENDFOR

*
* use this for uienabler method code (forces first page displayed to refresh correctly)
*
this.ActivePage = this.ActivePage  && or it can be proper hierarchy in the form.Init

* UIEnabler class/UIEnable code
LPARAMETERS lEnable
IF lEnable
  this.Parent.Refresh()		&& force refresh of parent (usually Page)
ENDIF
