HELLO EVERYONE

first.. i have a database...

dbName: Database
tblName: tblUser
FieldNames: UserID, UserPassword, UserType

example:

alc14647, 12345, admin
bti12345, 67890, user
ggt09876, 45673, editor
blah blah blah

my question is... how do i enabled or hide ex.[buttons or lables]
if the user type is logged in?

i have a SEPARATE LOG IN PAGE, and a MASTER PAGE for my layout and the other page is selected MASTER PAGE for the CONTENTS

ex. admin can see or enable to use a certain buttons or lables
and the user can only use or see a specific labels or buttons after log in,

my buttons or labels are

LABEL1
LABEL2
LABEL3
LABEL4
LABEL5
LABEL6
LABEL7
LABEL8
LABEL9

all the labels can see the ADMIN in the MASTER PAGE note[that labels is isn't the ContentPageHolder, i put it in the OUTSIDE]
and the other user can SEE that labels on their SPECIFIC type,

this my CODE for my SEPARATED Log in page and it's in the same project located also[hope you'v gonna get it^_^]

Imports System.Data.OleDb

Partial Class _Default
    Inherits System.Web.UI.Page
    Dim cn As New OleDbConnection
    Dim cmd As New OleDbCommand
    Dim dr As OleDbDataReader

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        txtUsername.Focus()
        Label1.Text = ""
        Try
            With cn
                If .State = Data.ConnectionState.Open Then .Close()
                .ConnectionString = "Provider=microsoft.jet.oledb.4.0;data source=" &; Server.MapPath("data\database.mdb")
                .Open()
            End With
        Catch ex As Exception
            MsgBox(ex.Message.ToString)
        End Try
    End Sub

Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click
        If txtUsername.Text = "" Or txtPassword.Text = "" Then Exit Sub
        With cmd
            .CommandText = "Select * from tbluser Where userid = '" & Trim(txtUsername.Text) & "' and passid = '" Trim(txtPassword.Text) &"' "
            .Connection = cn
            dr = .ExecuteReader
        End With

        If dr.HasRows Then
            Session("name") = txtUsername.Text 'it will display o the other page, it depends
            Response.Redirect("Main.aspx") 'my main.aspx is connected to my MASTER PAGE and all the other page
        Else
            Label1.Text = ("ERROR! " & txtUsername.Text)
