Pablo,
>Give me you suggests for convincing my boss to attend any DEVCON.
Idea exchange with your VFP peers in a setting that is both challenging technically (you will learn lots) and encouraging (you will build a network of close friends).
The classes cover a range of topics from beginner to very advanced, and are focused on making the language (and you) productive. You get a CD with white papers and code samples, from people who are (most of them) real developers with a depth of experience.
You can pick and choose the sessions that make most sense for the projects you are working on, or for filling in areas of knowledge where you do not yet have sufficient experience. You will learn of the lastest directions in Microsoft's product plans and strategies, and be able to talk with the VFP development, support and marketing people.
The exchange of ideas in between classes, during mealtimes, and throughout the conference, will help you to "bounce ideas" off of many VFP developers and will stimulate creative thinking, tempered with practicality born of experience.
It gives you a chance to get out of the day-to-day routine of work and learn in a fun, relaxed and exciting setting. You will go back home a happier developer, and therefore much more productive.
See ya there next year?
