How to use veriables across the application

 Try

            cnnUser = New SqlConnection(AppSettings("DbSqlPortal"))

            cmdUser = New SqlCommand("spAdminIsUserValidForLogin", cnnUser)

            cmdUser.CommandType = CommandType.StoredProcedure

            cmdUser.Parameters.Add("@UserName", SqlDbType.VarChar).Value = txtEmail.Text.Trim()

            cmdUser.Parameters.Add("@Password", SqlDbType.VarChar).Value = txtPassword.Text.Trim()

            ' cmdUser.Parameters.Add("@Password", SqlDbType.VarChar).Value = Convert.ToBase64String(hasedBytes)

            cnnUser.Open()

            drUser = cmdUser.ExecuteReader()

            If drUser.Read() Then

                

                'AndAlso (CBool(drUser("IsActive")) And CBool(drUser("IsAdmin"))) Then

                Session("LoggedInIsActive") = drUser("IsActive")

                Session("LoggedInIsAdmin") = drUser("IsAdmin")

                Session("LoggedInUserId") = drUser("UserId")

                Session("UserTypes") = drUser("UserTypes")

                LoggedInUserId = CInt(drUser("UserId"))

                Session("DistrictId") = CInt(drUser("DistrictId"))

                Session("LoggedInUserName") = drUser("Email")

                Session("LoggedInUserFullName") = drUser("FullName")
