This snippet is how you can do it procedurally:

SET CLASSLIB TO 'C:\PROGRAM FILES\MICROSOFT VISUAL FOXPRO 7\FFC\_CONTROLS.VCX' ADDITIVE

* This works
oFM = CREATEOBJECT( 'myTestForm' )
oFm.AddObject( 'oSize', '_resizable' )
oFM.AddObject( 'oGd', 'grid' )
oFM.oGd.Visible = .T.
oFM.Show(1)

DEFINE CLASS myTestForm As Form 
	PROCEDURE Resize
		IF TYPE( 'this.oSize' ) = 'O' AND NOT ISNULL( this.oSize )
			this.oSize.AdjustControls()
		ENDIF 
	ENDPROC 
ENDDEFINE 

Note that in the form class definition I call the oSize.AdjustControls object whenever the resize method of the form is invoked. Also, the filepath to the _controls.vcx may be different with your installation. The grid is for demonstration purposes only.
