Hi,
I am using flash builder 4 and would like to create a login system using flash builder 4 as the front end and php as the back end.  i found a tutorial that i found on the website but getting this error when i try to run it:
 "'HTTPService' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.      Login.mxml      /Login/src      line 27      Flex Problem"

However, i am not sure where i saved the php file is wrong or not as you see i saved the php file under this root ="C:\wamp\www\mylogin.php"
Pls help thanks

I'm not able to pass comment on your code, but I can suggest alternate ways of logging in using flex - try here - http://activeden.net/searches?term=login&type=files&categories=flex&sidebar_redirect=true

I cannot help with the Adobe Flex or Flash part, but I can show you the principles of a simple PHP authentication system.  I have an article here at EE that teaches the basics.  Please read it over and post back with any questions.  The only differences would be to replace the HTML forms with your Adobe equivalents.

Best of luck with your project, ~Ray

@karinos57: The grade of "C" is the worst possible grade you can give at EE.  I really meant it when I said, "Please read it over and post back with any questions."  But instead of posting back with questions, you wrote, "i am not gonna get the solution" and gave a bad grade.  How can we help you if we can't  have any dialog?

The activeden.net links looked pretty good to me.

i did not mean just to give u bad grades but there was no solution for almost 2 weaks and i thought you guys were only experts on php and not flex so i have decided to close it.  i have to buy the code from the activeden.net  and i thought they were going to show me how to do it but it is not free.  thanks anyway for all your efforts.

"Not free" is kind of relative, right?  If a script costs $100 and I can buy it or spend a day of my life writing the "new wheel" version of it, I am not going to write new code when I could buy it.  For me that would be the path of least cost and least resistance. The expression, "time is money" means to say that these are fungible commodities.  

Anyway, best of luck with the project. ~Ray
