问题 Is there a way to save an application state for save files in AIR for the desktop (Flex /AS3)? Thanks 回答1: You need to make sure all your classes are serializable, then serialize them and save them to a file when exiting the application.

You would similarly want a light text color for selection and a dark text color for deselected. I know I could do this

I can log in fine through a browser, and when only using ROR. However, when I try it through my Flex4 application, it will fail the first time but work the second time. What is happening, is inside the user_sessions_controller.rb I have a call to self.current_user.to_xml; The first time I call the create action, the current

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago .

It's worth noting, however, that Flex 4 is still in development, and they don't even consider it beta

问题 I'm a complete newbie to Flex, so apologies for my dumbness. I've searched for an answer but haven't found anything that seems to be doing the trick. What I'm trying to do: port this example http://www.adobe.com/devnet/air/flex/articles/flex_air_codebase_print.html to Flash Builder 4. All seems to be fine but for one thing.
