Mathew,

>Three questions?

You should probably have posted this as two separate messages.... to keep threads coherent.

>1. Is there a limit in VFP for the number of new methods you can create?

I do not know of any limit to the number of methods you can add to any given subclass. If there is a limit, no good class design would ever come close to hitting it. Classes should have well defined operation. You shouldn't have just one class that does everything under the sun, Have several small classes that each do their own little thing.

I'm not sure I'm following your question. VFP does not allow multiple inheritance. A form can contain any number of objects derived from any number of classes. When you add methods in the designer these methods can only be added to the outermost entity. If you have a form class that you've already dropped a class into, you can not add methods to that contained class. You have to go back to the class itself and add the method.

>3. How can I enabled and disabled toolbar buttons based on user's selection?

You can provide whatever logic you need to set the Enabled property of the objects in the toolbar.
