Summary

This chapter covered a lot. You saw how to consume a Web service from a Web application and how to hook that same application up to your original components. You examined how to handle client-side rules without code and received a little lesson on regular expressions. You gained some insight on what Web page developers must go through as opposed to what a Windows forms developer must go through. But mostly you have gained the insight that a well-coded data-centric component can save you a lot of headaches and that displaying business errors is pretty easy once you figure out how to report the errors to the user.

In addition, you learned how to store database credentials in the registry and how to retrieve those credentials in a secure manner. You examined a host of security issues that allow you to determine what possible security issues you might face on a particular project and how to get around some of them.

In the next chapter you will globalize and localize both your Windows forms application and your Web forms application so that you will have hands-on experience with how to modify an application to accommodate different languages.
