im try using data reader on class but it doesnt work correctly. Here is my Class :<br/>
<pre class="prettyprint lang-vb Imports System.Data.OleDb
Public Class ClassDB
Protected myCMD As New OleDbCommand
Protected myCON As New OleDbConnection
Protected myDR As OleDbDataReader
Public Sub Connect()
Try
myCON = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:Database FileDatabase.mdb;Persist Security Info=True")
myCON.Open()
Catch ex As Exception
End Try
End Sub

Public Function ExDataReader(sqlString As String) As OleDbDataReader
Try
myCMD = New OleDbCommand(sqlString, myCON)
myDR = myCMD.ExecuteReader
Catch ex As Exception
End Try
Return myDR
End Function

Public ReadOnly Property GetDR
Get
Return myDR
End Get
End Property
End Class[/code]
and then i use that class to fill my list view <br/>
<br/>
<pre class="prettyprint lang-vb
Public Class Form1

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
Dim myLV As ListViewItem
With ListView1
.Clear()
.GridLines = True
.View = View.Details
.Columns.Add("ID")
.Columns.Add("Nick")
.Columns.Add("Phone")
.Columns.Add("Mail")
.Columns.Add("Address")
End With

Dim myObject As New ClassDB

myObject.Connect()
Do While myObject.ExDataReader("SELECT * FROM MasterMember").Read
myLV = ListView1.Items.Add(myObject.GetDR.Item(0).ToString)
myLV.SubItems.Add(myObject.GetDR.Item(1).ToString)
myLV.SubItems.Add(myObject.GetDR.Item(2).ToString)
myLV.SubItems.Add(myObject.GetDR.Item(3).ToString)
myLV.SubItems.Add(myObject.GetDR.Item(4).ToString)
Loop

End Sub
End Class[/code]
