Thanks for your reply Hilmar. From the previous posts in this thread I came up with a simple solution for my prob.

x =1 
FOR EACH oControl IN Thisform.Controls
    IF UPPER(Thisform.Controls(x).Baseclass)=UPPER("commandbutton")
    	Thisform.cambianombre(x)  &&& just a sample method where you
                                  &&& can do anything you want with the 
                                  &&& control(s) that meet the criteria
    ELSE
    	IF UPPER(Thisform.Controls(x).Baseclass)=UPPER("container")
	   Thisform.llamada(oControl) &&& sample method to do whatever
                                      &&& you want to do with a control
                                      &&& inside a container placed on
                                      &&& the form
    	ENDIF 
    Endif
	x=x+1
NEXT 

I know this method has some flaws, for instance it's not fully recursive and you have to handcode the baseclass of the controls you want to cicle through.
