In VFP, there usually isn't any need to do this. If you want to affect all TextBoxes on a form, you can do ThisForm.SetAll('ReadOnly', .T., 'textbox') (or 'txtMySubClass', if you've been subclassing everything. If you want to affect only a few (say, an address box you want to pop in and out), you can put the controls in a Container control and do ThisForm.cntAddress.SetAll('Visible', .T.).

That give you some ideas, or am I missing your point?
