I got this far opening the excel sheet:

VB Code:
  1. Dim excelsheet As New Application
  2.         Dim filepath As String
  3.         filepath = TextBox1.Text
  4.         excelsheet.Workbooks.Open(filepath)
  5.         Dim xlWsheet As Worksheet = excelsheet.Worksheets("Sheet1")
  6.         Dim r As Range = xlWsheet.UsedRange
  7.  
  8.         MsgBox(r.Cells(1, 1).Value)

I get the first row displayed on the MessageBox, however that was for testing only. How would I go about placing all values in that column into a checked List Box? I am using VS 2005
