  - by Frost Li

  I saw these lines in a demo project, but I couldn't understand why it did that. [self willChangeValueForKey:@"names"]; [self didChangeValueForKey:@"names"]; It called didChangeValueForKey immediately after willChangeeValueForKey. Does it make any sense? Furthermore, when should be the right time to call this two methods? Thanks a lot!! :)

• Decorator Design Pattern Use With Service Objects (wSingleton)

  - by Dustin

  I'm working on a project where I need to add some functionality to a service object and using a decorator to add it in seems like a good fit. However, I've only ever used decorators with simple beans, never on a singleton like a service object. Has anyone ever done this before and what are the pros and cons? In this case I don't think creating a subclass will work so a decorator seems to be a good fit. What are your thoughts on doing this?

• Porting from MS Access

  - by lacqui

  I've recently been given a MS Access .mdb database file and asked to make it usable in a Linux system. What I'm looking for is a way to convert the Access database to an open-source database such as MySQL or PostGres. I don't have MS Office, and it's a one-time project for a volunteer organization so I don't want to spend money if it's avoidable. I'm running Vista x64, and have a Linux virtualbox, so something usable in either one will be good.
