Gan,

You don't need the value of n, use a FOR EACH/ENDFOR loop. It's in the help file and it will iterate through a collection without telling it how many items are in the collection.

FOR EACH oCont IN Thisform.Controls
    oCont.Name = oCont.Name + "123"
ENDFOR

Ed is right in that you must recursively process such objects as Grids, PageFrames, Pages, Containers, etc. because they contain objects inside of themselves.
