Upgrade code from VB6 to VB.NET

[solartorch]

Hi guys,

I used to use VB6 to program. Now I'm trying to upgrade to VB.NET.
My idea of this small program is this
1, read data from Excel
2, draw rectangle using the data

Follows my code

Option Explicit

  Dim X1 As Integer
  Dim X2 As Integer
  Dim Y1 As Integer
  Dim Y2 As Integer
  
  

Private Sub Form_Load()

Dim oXLApp As Excel.Application         'Declare the object variables
Dim oXLBook As Excel.Workbook
Dim oXLSheet As Excel.Worksheet

  Set oXLApp = New Excel.Application    'Create a new instance of Excel
  Set oXLBook = oXLApp.Workbooks.Open("D:\New Folder\Book1") 'Open an existing workbook

  Set oXLSheet = oXLBook.Worksheets(1)  'Work with the first worksheet
  
Dim my_variable As String
my_variable = "hello"
oXLSheet.Cells(2, 1).Value = my_variable

X1 = oXLSheet.Cells(1, 1).Value
Y1 = oXLSheet.Cells(1, 2).Value
X2 = oXLSheet.Cells(1, 3).Value
Y2 = oXLSheet.Cells(1, 4).Value

oXLApp.Visible = True                'Show it to the user
  Set oXLSheet = Nothing               'Disconnect from all Excel objects (let the user take over)
  Set oXLBook = Nothing
  Set oXLApp = Nothing


End Sub


Private Sub Form_Resize()
Me.Scale (0, 0)-(200, 200)
Me.Cls
Me.Line (X1, Y1)-(X2, Y2), vbYellow, BF
Me.CurrentX = X1
Me.CurrentY = Y1
Me.Print "CW1"

End Sub

Could anyone tell me what's the modification I should carry out? I'm using Visual Studio 2005 Professional Edition now
Any help will be very appriciated.
