yeap just realized that. So far I've been using cookies but i ran across a few more problems.

This is part of my code from the button. Basically A means admin and B means employee.

If str1 = txt1 And str2 = txt2 And txt3 = "A" Then
Response.Cookies("ckusername").Value = 1
Response.Cookies("ckusername").Expires=DateTime.Now.AddDays(1)
Response.Redirect("admin.aspx")


ElseIf str1 = txt1 And str2 = txt2 And txt3 = "B" Then
Response.Cookies("ckusername").Value = 2
Response.Redirect("employee.aspx")
End If


I'm trying to get it so that it will only an admin to access a certain page or vise versa only if they got the correct value. On the admin page that I want employees to stay out I've added this code to the form load.

Dim objckusername As HttpCookie
objckusername = Request.Cookies("ckusername")
If objckusername.Value = 1 Then
//continue loading page

ElseIf objckusername.Value = 2 or objckusername.Value = NOTHING Then
Response.Redirect("main.aspx") //back to login page
End If

This code seems to be working fine after I log in as the employee and try to get into the admin page cause it kicks me back to the main page as it should cause i don't have the correct value in my cookie.

The problem right now is that say I choose to skip login and type the direct web address to say the admin page without logging in, instead of getting redirected back to main I get an error.
