We will not write your application for you. Well I will, at my hourly rate, contact me off list if you want to hire me. If you want any more help from me you will need to show what you are doing. To start with, post your login HTTPService declaration code and your result handler code.

[flexcoders] Re: geting info of a user who has loged in
I use PHP and WebORb for PHP so anything I show will use that.
Please do not ask for a tutorial using something else.
There should be enough here for you to extrapolate for use with any
language.
This is a quick and dirty example that hard codes things. In a real
application
I would loosely couple everything with events.
My Flex project is set up with a couple of folders called components and
ValueObjects.
The main Application file (login_example.mxml):
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute xmlns:view=components.*
applicationComplete=doApplicationComplete()
mx:Script
![CDATA[
import ValueObjects.UserCredentials;
import components.*;
import mx.managers.PopUpManager;
import mx.core.IFlexDisplayObject;
private var myLoginForm:IFlexDisplayObject;
private function doApplicationComplete():void
{
myLoginForm = PopUpManager.createPopUp(this, login,
true);
}
public function
doLogin(userCredentials:UserCredentials):void
{
viewstack1.selectedChild = admin;
admin.userCredentials = userCredentials;
}
]]
/mx:Script
mx:ViewStack x=0 y=26 id=viewstack1 width=100%
height=100%
view:Home id=home/
view:Admin id=admin/
/mx:ViewStack
/mx:Application
This has a view stack for each view - Admin and Home. There are also a
couple of functions.
doApplicationComplete is called on applicationComplete event and
instantiates the login
window. doLogin is called from the login component if login is
successful. It poulates the
userCredentials variable of the Admin component.
==
components/Home.mxml:
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;

This is just a container for the background of the login window at
startup.

[flexcoders] Re: geting info of a user who has loged in
For simplicity's sake, I would add a public var to your Admin component and populate it with pop.username_txt.text: viewstack1.selectedChild = admin; admin.username = pop.username_txt.text; In your Admin component's creationComplete handler, you would have another RemoteObject call to gather user data for the user that was passed above. I would recommend reading some tutorials about how to use ColdFusion and Flex (I don't use ColdFusion - I use PHP): http://flexcf.com/tutorials http://www.adobe.com/devnet/coldfusion/articles/data_app.html http://www.adobe.com/devnet/flex/articles/coldfusionflex_part1.html http://tutorial512.easycfm.com/ --- In flexcoders@yahoogroups.com, stinasius stinas...@... wrote: hi this is my the login code functionality am using that i got from flex cookbook example and works perfect.

yes i have implemented the login functionality and its working. nw i am faced with the issue of showing the details of the logged in user. any help?
Re: [flexcoders] Re: geting info of a user who has loged in
If you implemented le login functionality, then you should have some mechanism (httpservice, rpc ...) to exchange data with the server to send login info and get a response back. Just use the same mechanisms to send a request and get the data back.

[flexcoders] Re: geting info of a user who has loged in
yes just pass the info back to the httpservice
maybe this example will help you
http://blog.flexexamples.com/2007/10/29/passing-parameters-to-an-httpservice/
you call the httpservice upon login button clicked
login.send();
and then the httpservice provider passes the login to your backend code
