[RESOLVED] Need more help understanding Classes

[Barrabutus]

Hi Guys

As I said in my prior post I am trying to get to grips with Classes and how to use them "efficiently", So bearing this in mind I decided to create a small class driven application.

I am struggling to understand how I can "use" this new instance of this user somewhere else.


Test Data was
Name : Joe
username : JoeBloggs
Password : JoesPassword

Then

Name : John
Username : JohnDoe
Password : JohnsPassword


Now this updates the listbox with Joe and John in each row.

The Form Code is. 3 Textboxes, 1 Button , 1 Listbox, 2Labels.

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If (txtName.Text = "") Then
            MsgBox("ERROR ENTER CLASS NAME")
        Else
            'Create a new user object. I tried to create a "unique" object name by passing the txtName.text value but it throws errors getName is not member of string..
            'Dim txtName.text As New user
 
            Dim newObject As New user
            newObject.setDetails(txtUsername.Text, txtPassword.Text, txtName.Text)
            lstUsers.Items.Add(newObject.getName())
        End If
    End Sub

    Private Sub lstUsers_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstUsers.SelectedIndexChanged
        Dim users As user
        users.getLogins(lstUsers.SelectedItem)
    End Sub
End Class

Which is handled by this class.

Public Class user
    Dim name As String
    Dim username As String
    Dim password As String
    Public Sub setDetails(ByVal argusername As String, ByVal argpassword As String, ByVal argName As String)
        name = argName
        username = argusername
        password = argpassword
    End Sub

    Public Function getName()
        Return name
    End Function

    Public Function getLogins(ByVal userObject As Object)
        Form1.Label1.Text = username
        Form1.Label2.Text = password
        Return Nothing

    End Function

End Class

Now this works and updates the listbox with the new instance of the user but how can I use that instance from the listBox control to retrieve that users details??

Many Thanks Barra.
