Ever had the need for an application framework? You know, the kind where you need navigation at the top, a panel on the left and/or right for something, and a status block at the bottom. Then, the center/main part would be a module-like... specific to the app you're in? Kinda like Miscrosoft's Office Outlook works... tasks/mail/calendar aren't in seperate windows, they are all in the same application (tasks doesn't open in a new window).
This is a module like framework. Developer Express has a nice article about a framework they built with source code. The first half is generic.. not using their components. The latter half is using their components. The first part is what interested me. Very cool.
