splitting a string into 2?

hi...i've managed to upload a .txt file into a comboBox and now i'm trying split each line into 2 ,1st part of line goes to comboBox where the 2nd part goes to lbl.text....so far , i can get 1st part shown in comboBox but the 2nd part nowhere to be found..here the code~:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim ProductSplit(2) As String
Dim sw As StreamWriter
Dim sr As StreamReader
Dim fileName As String = "E:\...ProductList.txt"
Dim i As Integer
If (File.Exists(fileName)) Then
sr = File.OpenText(fileName)
Do While (sr.Peek <> -1)
LineOfProduct = sr.ReadLine
ProductSplit = Split(LineOfProduct, ",")

cobProduct.Items.Add(ProductSplit(0))
lblUnitPrice.Text = ProductSplit(1)


Loop

Else
MsgBox("file does not exist")
End If
sw.writerLine(fileName)

sw.Close()

also there are 2 other things i'd like to help me out with plezase
1- an error on sw.writerLine(fileName) it says writerLine is not part of system.io.steamwriter.??
2- how do u get indexes or items selected when u select one of them in 2 or 3 listboxes, for instance u want to remove an item u select it, and automaticly its quantity and price get selected as well??
Thank u people in advance..u've been great

Is your code giving you an error? If so where at?

Also you shouldn't specific the number of elements of the array if you are going to use it with split, change:
Dim ProductSplit(2) As String
TO:
Dim ProductSplit() As String

As for Q#2 there is no WriterLine there is a WRITELINE (no R). Although you haven't declared an instance of the streamwriter or given it a stream to work with. What is this part suppose to do?

As for syncing up multiple listboxs you should put the data in to a class and then all of it will be in one place and easier to sync.

Try something like this:

VB Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
   Dim ProductSplit() As String 
   'Dim sw As StreamWriter 
   Dim fileName As String = "E:\...ProductList.txt" 
 
   If (File.Exists(fileName)) Then 
      Dim sr As StreamReader= File.OpenText(fileName) 
      Do While (sr.Peek <> -1) 
         LineOfProduct = sr.ReadLine 
         ProductSplit = String.Split(LineOfProduct, ",") 
   
         cobProduct.Items.Add(ProductSplit(0)) 
         lblUnitPrice.Text = ProductSplit(1) 
      Loop 
      sr.Close
   Else 
      MsgBox("file does not exist") 
   End If 
'sw.writerLine(fileName) 
'sw.Close()

As for a class this should get you started:

VB Code:

Public Class Product
  Private _ProductName as string
  Private _UnitPrice as Single
  Private _Quanity as Short
 
  Public Property ProductName as string
    Get
        return _ProductName
    End Get
    Set(Value as String)
        _ProductName=Value
    End Set
  End Property
 
  Public Property UnitPrice as Single
    Get
        return _UnitPrice 
    End Get
    Set(Value as Single)
        _UnitPrice =Value
    End Set
  End Property
 
  Public Property Quanity as Short
    Get
        return _Quanity 
    End Get
    Set(Value as Short)
        _Quanity =Value
    End Set
  End Property
 
   Public Sub New()
      MyBase.New
   End Sub
 
   Public Sub New(Name as string,UnitPrice as single)
     _ProductName=Name
     _UnitPrice=UnitPrice
     _Quanity=0
  End Sub
 
   Public Sub New(Name as string,UnitPrice as single,Quanity as short)
     _ProductName=Name
     _UnitPrice=UnitPrice
     _Quanity=Quanity
  End Sub
 
End Class
 
'then instead of loading the individual data you'd load it into a class and bind the class to the different UI parts.
 
Private Products as ArrayList
 
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
   Dim ProductSplit() As String 
   'Dim sw As StreamWriter 
   Dim fileName As String = "E:\...ProductList.txt" 
 
   If (File.Exists(fileName)) Then 
      Dim sr As StreamReader= File.OpenText(fileName) 
      Do While (sr.Peek <> -1) 
         LineOfProduct = sr.ReadLine 
         ProductSplit = String.Split(LineOfProduct, ",") 
   
         dim itm as New Product(ProductSplit(0),CType(ProductSplit(1),Single))
         Products.Add(itm)
      Loop 
      sr.Close
      cobProduct.DataSource=Products
      cobProduct.DisplayMember="ProductName"
      lblUnitPrice.Text=Products(0).UnitPrice
   Else 
      MsgBox("file does not exist") 
   End If 
'sw.writerLine(fileName) 
'sw.Close() 
 
 
[color=red]THEN IN THE COMBO CHANGE EVENT YOU CAN SET THE OTHER ITEMS EASILY[/color]
    Private Sub cobProduct_SelectionChangeCommitted(ByVal sender As Object, ByVal e As System.EventArgs) Handles cobProduct.SelectionChangeCommitted
        If Not cobProduct.SelectedItem Is Nothing Then
           dim cur as Product=CType(cobProduct.SelectedItem,Product)
           lblUnitPrice.Text=cur.UnitPrice
        End If
    End Sub
