Hi!

Create a container class. Put a control inside it and give it some name. Create a form. Put the object of that container class on the form. Try to change the name of the control inside of the container. VFP will not allow this becaus ethat control is part of the class.

In your case all is the same - object inside f the form is really a part of the form class (form is also a container), so you cannot change its name.

By the way, changing of the control name is needed very rarely. I wondered, why you need to do this?
