Then put the username into a session on login:

Session("usernamen") = login1.Username

Then it doesn't matter from or how you access your default2.aspx. There you just readout the session to get the user:

 Dim yourUser as Membershipuser = Membership.GetUser(Session("username"),True)

hi

i have problem again :)

i have added code.. it is below.. and it works.. but it is work for one user... new problem is when second user login, button1(insert button) work for second user... also first user click button1, see email and username of seconduser . but first user should see email and username of first user....i open two exploerer and i have tryed it.. but this code Dim yourUser As MembershipUser = Membership.GetUser(Request.QueryString("user"), True) work for each user... first user see email and username of first user .. also second user see email and username of second user in the same time. but session ("username") doesnt work same time for each user... it shows username and email of last user login :)

'Response.Redirect(String.Format("default.aspx?user={0}", Login1.UserName))

End Sub

'TextBox4.Text = Membership.GetUser(LoginStatus1.UniqueID).ToString

' TextBox4.Text = User.Identity.IsAuthenticated.

If Request.QueryString Is Nothing Then

Exit Sub

End If

Dim yourUser As MembershipUser = Membership.GetUser(Session("username").ToString, True)

Dim userGuid As System.Guid = DirectCast(yourUser.ProviderUserKey, Guid)

End Sub

You can use Application("user") if you want to try that. Maybe this works for you

hi 

application ("username") work like session ("username") :)

i see email and username of last user login :)

Last idea I have is to use a cookie and check this one each time 

cookie ?? what is it ?? could you write to me how i check cookie ? :)

cookies are small files which are saved on the client machine. Their you save for examples your password files to automatically login your page.

So how to set and read them:
