1. CairngormEvent is specific to Cairngorm framework, so all kind of fun you get with Cairngorm, will 'actually be a fun' only if u play with CairngormEvent. For instance, if you want to map an event with a command inside the controller, you can do it only with a CairngormEvent (since Command and Controller are Cairngorm-specific entities). In an enterprise application, you always have a top-level framework and an application level framework. Cairngorm basically can help you in building the top-level framework, but for application-specific stuff, you need some kind of non-cairngorm events, which you can use to some simple stuff like - passing values between components, sending a notification for any user gesture, etc. This can be done by Flex Events/Custom Events.
Also, when dispatching events from components, try dispatching a Custom / Flex event. This makes sure that the component is loosely coupled. There is also a syntax difference between them, when you dispatch the event. 2. Try using ASyncToken, while making service calls. This helps you in tracking the result. (Let me know if you require any code/samples for this). You can also dispatch events on getting results. Add an listener for the events, and you can know the dispatcher. 3. ??????????????? 4. HTTPService and WebServices- both gets you data from any backend. There are many reasons as to why one should go for HTTPService or WebService. For a general case, Google would be able to help u out more. You can post a specific use-case, for which you can ask this question. 5. ??????????????? :) Hope this helps.. (Not the question marks for sure.. ;)) -Gaurav On Tue, Aug 10, 2010 at 7:43 PM, bikramjit singh <[email protected]>wrote: > 1.i found...cairngorm we get from cairngorm class ...and event from event > class.....both have diff dispatcher method... > but can we use simple event in cairngorm....we can dispach simple event to > controller and register with command..why we go with cairngorm...can anybody > plz explain me this.......and whts the difference....can we use simple event > in cairngorm framework > > 2.one more confusion in my mind...like if we are using synchronized method > in java side...and we r calling throungh remote object...like we have > hundred client....every client hv access the same method so they hv to wait > until first will done with his work because method is synchronized...its > take too much time.like every client hv to wait because lock is acquired by > other client...how we can resolve this probem.... > 3.if method is not sychronized....then i can send multiple request..through > remote object....because using remote object we can send multiple > request...because they are asynhronous... > 4.like i know we use remote object to get java data from datbase using > java classes....we configure java classes in remote config. xml...and from > front end we call middle tier with help of blazeds......i am confuse with > when we use http and webservices...and how can we decide which one is best > for our project. > > 5.i knw in java we have to call garbage collector we can call by > system.gc...in flex we can call like go in profiling and then we have a > button garbage collector.... > like we have any prograaming line in mxml or action script like we call > like we call in java system.gc > > > > Please help me here how i can resolve these problem > > thanks. > > -- > You received this message because you are subscribed to the Google Groups > "Flex India Community" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<flex_india%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/flex_india?hl=en. > -- You received this message because you are subscribed to the Google Groups "Flex India Community" group.
