Hi,


    I need to do code on log in even.
    Actually i have a shopping cart that maintains before log in through
    session id. now i need to change a status when use logs in.
    Please help.
  
   It's urgent...

Is this login through a site that is not a DotNetNuke site?

No no....

I need to implement some code on login event... means i need to do some update on my data base when use log in into DNN site.

This might be a good time to look at Dynamic Login from Datasprings. It will allow you to do all sorts of things when a user logs in. Best of all, it will not do this by modifying framework code, so you will be able to upgrade later.
