As many have said, you can alter the VFP base classes. You need to subclass them and use these.

To move to the second part of your question, about implimenting this in your application. Since you will have to make the required changes to your baseclass obviously recompiling itsn't going to change anything.

You will have to change the class on your forms. You can do this by opening the .scx file as a table and updating the records so that the objects are based on your base class rather than VFP's.

Once you have done that your changes will be reflected in the application.
