[RESOLVED] [2005] Class doesnt store values

hi all!!
wonder why my class doesn't store the values???

the class

Code:

---

Imports Microsoft.VisualBasic

Public Class Strings

    Private _user As String = ""

    Property User() As String
        Get
            Return _user
        End Get
        Set(ByVal value As String)
            _user = value
        End Set
    End Property


End Class

---

the login:

Code:

---

Sub dologin(ByVal Source As Object, ByVal E As EventArgs)

        Dim strConn As String = (ConfigurationManager.ConnectionStrings _
            ("GesQualConnectionString").ConnectionString)

        Dim MySQL As String = "Select ID, Utilizador , Pass ," & _
        "AlterarPass from Users Where Utilizador = '" & _
        TxtUser.Text & "' and Pass = '" & Uteis.GeraHash(TxtPass.Text) & "'"

        Dim MyConn As New SqlConnection(strConn)
        Dim Cmd As New SqlCommand(MySQL, MyConn)

        MyConn.Open()
        objDR = Cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)

        If Not objDR.Read() Then
            LblResposta.Text = "<h1><b>User / Pass Inválidos !</b></h1></p>"
            While objDR.Read()
                strNome = objDR("Utilizador")
                intCode = objDR("ID")
                bprimeirologin = objDR("AlterarPass")
            End While

            Session("ID") = intCode
            Session("Utilizador") = strNome

            Dim clsStrings As New Strings
            clsStrings.User = strNome

            objDR.Close()
            MyConn.Close()
        Else
            objDR.Close()
            MyConn.Open()

         
            If bprimeirologin Then
                Response.Redirect("~\MudaPass.aspx")
            Else
                Response.Redirect("~\Default.aspx")
            End If

        End If

    End Sub

---

and the call:

Code:

---

Protected Sub Page_Load(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Me.Load

        Dim ClsStrings As New Strings
        Label1.Text = ClsStrings.User


    End Sub

---

Code:

---

Dim clsStrings As New Strings

---

The above code in ur program automatically deletes the previous value. And also I can't understand what u trying to do. Because this is not declared public. Explain the code for exact answer.

thanks senthilkumartd!!!
i need to store some strings to use in other pages!
provided by the login page, such as UserName and so on!
wanted to keep them in the strings class
and get them when i want to use them

ok it is public now but still doesn't work:

Code:

---

Public Class Strings

    Private Shared _user As String = ""

    Public Shared Property User() As String
        Get
            Return _user
        End Get
        Set(ByVal value As String)
            _user = value
        End Set
    End Property


End Class

Your object for the Strings class are only stored for the life time of the dologin method. If you want to access the object with another method you will have to instantiate the object in the class level of whatever class dologin resides in. that way any method in the class that dologin reside in can access all public methods of the Strings class.

This is a surreal thread. I see a class designed to store a string. Almost redundant. And then nobody mentions session variables.

Motorui, store the username in a session variable.

Session("username") = strNome

Then in another page,

Label1.Text = Session("username").ToString()

Kudos mendhack... for something this simple, session variables is the wya to go. Even if the data was complex, creating the class, setting the properties, then STORE THE CLASS IN THE SESSION VARIABLE would be the way to go. Simply putting the data into a class doesn't make it appear on the other side. It needs to be stored and sent, jsut like anything else.

thanks all!
i will use session
sorry about this but I'm still noob!
hehehe

one more question
how to add select statement value to session??

i tried this it does the login just fine but doesn't store the user name in session:

Code:

---

Dim strConn As String = (ConfigurationManager.ConnectionStrings _
            ("GesQualConnectionString").ConnectionString)

        Dim MySQL As String = "SELECT UH ," & _
        "Utilizador, LControl, CheckIn, Placa, LostFound, Admin " & _
        " FROM Users Where Utilizador = '" & _
        TxtUser.Text & "' and Pass = '" & Uteis.GeraHash(TxtPass.Text) & "'"

        Dim MyConn As New SqlConnection(strConn)
        Dim Cmd As New SqlCommand(MySQL, MyConn)

        MyConn.Open()
        objDR = Cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)

        If Not objDR.Read() Then
            LblResposta.Text = "<h1><b>User / Pass Inválidos !</b></h1></p>"
            While objDR.Read()
                strNome = objDR("Utilizador")
                intCode = objDR("ID")
            End While

            objDR.Close()
            MyConn.Close()

        Else
            objDR.Close()
            MyConn.Open()

            Session("User") = strNome


            If bprimeirologin Then
                Response.Redirect("~\MudaPass.aspx")
            Else
                Response.Redirect("~\Default.aspx")
            End If

        End If

    End Sub

1. Don't put SQL statements in session variables. You're better off creating a stored procedure that does this SELECT for you. You simply pass the username to it.

2. You've assigned strNome in the 'if' portion of your 'if-then-else' block, but you attempt to access it in the 'else' portion. It's not going to work, since only the 'if' portion or the 'else' portion will be executed, but not both. From your code I see that Utilizador is the same as TxtUser.Text, so you should say:

Session("User") = TxtUser.Text

And do this before the if block.

i started with user name just to test it! i need to retrieve to session other
items in the database!
i will try with a stored procedure!
and post here the result
thanks
