how to detect whether is a user is logged in or not from IE Toolbar
-
Hi I have developed an IE toolbar in ATL,COM,WTL and without using MFC.This toolbar is for a particular site.This is having a sign in button on clicking which user will be navigated to sign in page of our site.After signing in the toolbar will be changed,means it will be having some extra buttons on it.when the user will click logout,the toolbar will be back to its previous state.Means this is like yahoo toolbar.Upto this part I have made it perfect.I have done MySql database connectivity from my toolbar.Now the problem what I am facing is that: if any user logs in our site and then he dose not do anything in the site for 20 minutes his session expires,means nothing will work in the site after idle 20 minutes,the user needs to sign in again.Now in that moment also I need to change the toolbar(I need to get the the toolbar in signed out state).How can I do it?Can anybody plz help me with some sample code?
