RE: [flexcoders] Newbie SOA question (maintaining login state)
I'd be interested in hearing more about this. Isn't there a 'normal' way to do this with flex? Maintaining login state would seem to be a basic requirement for web apps. Just curious. Tracy Spratt wrote: I have a lot to learn about security, and had difficulty wading through all of the levels and options, so I devised my own programmatic solution. When a user logs in from the Flex app (md5 hash on the password), I create a sessionId, store it in a hashtable in the .net app, and pass it back to the Flex app. The Flex app sends this token with each call. The server checks the passed in session id and compares the timestamp to the current time. If it is within the timeout period specified, it updates the timestamp and authorizes the call. If authorization fails, the user must log in again. I am certainly open to a better approach.

So basically, the user logs in, then stores a login token internally on the Flex side so that each web service call can be authenticated as being made by someone who has already logged in to the system. Does anyone have any ideas on how to approach this? My initial approach was to cache the user's username/password and authenticate on each web service call (Direct Authentication). I was told, for obvious reasons, that this is insecure method and requires database hit each call. I am trying to implement WSE 3.0 enabled web services on the .NET side. Is this an SSO problem, or should I be using STS/Brokered Authentication approach? We just started our upgrade to VS2008, so maybe I should just pursue WCF methods instead? Any experiences with this would be greatly appreciated.

[flexcoders] How to open a flex project that was created elsewhere?
I've downloaded a sample flex application, how do I open it in the flex builder 3 IDE? There is no 'Open Project' menu option, only New...Flex Project and so forth? -- View this message in context: http://www.nabble.com/How-to-open-a-flex-project-that-was-created-elsewhere--tf4923183.html#a14088912 Sent from the FlexCoders mailing list archive at Nabble.com.
Re: [flexcoders] How to open a flex project that was created elsewhere?
Maybe that works in Flex 2, but the menu options in Flex 3 beta 2 are different. Import, then Flex Project, but it want a zip file. The project I'm working with isn't in zip format, it's a folder inside a zip that contains other stuff...iow it's does not seem to be a 'flex project archive'.

RE: [flexcoders] Flex for database apps; compare to .net
I'm pretty new to .net also, so I suppose flex data services would be about the same learning curve. FDS, would it have any advantages over taking a .net approach? I seem to recall that FDS/LCDS has two way update notification/synching services or something of that order, which I took to mean that the flex ui would be updated passively if changes are made to the viewed data by another user? Would that be hard to emulate in .net, or would fluorine or WebOrb be able to help with that? Fluorine would connect flex and the .net side. But I'm not clear what the .net methods that you describe are exactly? Would they be a set of classes that call sprocs in the sql server db, either built manually or as generated by an ORM? I'm not clear on the limitations of the free version of LCDS, and what it costs if you need to go beyond the limitations of the free version? Samuel R. Neff wrote: Flex does not talk to a database directly (except with AIR but I gather you're talking about a web app). Flex talks to a back end which then can talk to a database.

Re: [flexcoders] Flex for database apps; compare to .net
Thanks, I'll focus on 3.0, though being new to flex and with the docs for 3.0 somewhat thin now, not sure what I'll be able to figure out. I hope adobe provides some straightforward db oriented tutorials, web services play only a minor role in most of my fellow developer's workload, db interaction is where it's at. I'd appreciate anyone else's input on these subjects.

It looks to me like opportunity to map the same objects on both sides of the data tier (http://flex.sys-con.com/read/418939.htm#) could give us the best of both worlds - the advantage of sproc-based data-managment filtered by .net assemblies feeding the Flex's rich UI.
