Add this method to the pageframe,
it is a horrible solution,
but without structuring the object it is better difficult to do of

MemberOrderToObject(iOrder)
IF this.Objects[m.iOrder].PageOrder=m.iOrder && MORE FREQUENTLY CASE
    RETURN this.Objects[m.iOrder]
ENDIF
Private iIndex
FOR iIndex=1 TO this.Objects
   IF this.Objects[m.iIndex].PageOrder=m.iOrder
      RETURN this.Objects[m.iOrder]
   ENDIF
NEXT

A best solution is to add the MemberIndex property to all VFP classes
and to write the whole code to manage it in
- Member.Init
- RemoveObject
- AddObject
-.....
