I am creating a toolbar in ATL,COM and WTL, not using MFC.Now I want to add the
feature of changing the toolbar depending on sign in and sign
out.after sign in if the user is a registered one then he should see
some buttons which are not present at the time when the user is not
signed in.Means I want to add the feature which is already present in
yahoo toolbar.But how to do it?How can I trap whether user is signed
in or not?
