Dan,
Be VERY careful if you are going to write to the Reserved/Properties/Methods memos, it's very easy to get VFP confused to the point that it won't load the class/form.
>Wow. That's very cool. It even distinguishes between properties and methods by placing a * in front of the name for methods. Just tested adding a property in the Reserved3 field and setting a value in the properties field. It adds a lot of design time possibilities.
