    : Exactly what are yout trying to do? First, you need to add a reference to the excel object library. After that, you can access the excel object model. But here's a lil code to help you get started:

    Dim oExcel As Excel.Application
    Dim oDoc As Excel.Workbook
    Dim oWorksheet As Excel.Worksheet

    oExcel = New Excel.Application
    oExcel.Visible = False
    'oExcel.WindowState = XlWindowState.xlMinimized

    oDoc = oExcel.Workbooks.Open(FileName) 'FileName is the full path and
    'name of the excel document.Ex:
    '"C:File.xls"
    For i = 1 To oDoc.Worksheets.Count
    oWorksheet = oDoc.Worksheets.Item(i) 'Loop through each worksheet
    'Now that you have a reference to the worksheet,
    'you can access the properties and methods
    'of a worksheet to retrieve the data that is needed.
    Next

    Hope this helps>>>

    Why do I get this message
    Type Excel.Aplication not defined
    I've added the Excel 11.0 object Library from the Add Reference box
    is there still something missing?

    This is a Cut and Paste of all the code, I cannot see anything out of the ordinary do you. I am using Visual Studio 2005 with the MSDN Object Libraries installed.

    Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim oExcel As Excel.Application
    Dim oDoc As Excel.Workbook
    Dim oWorksheet As Excel.Worksheet

    oExcel = New Excel.Application
    oExcel.Visible = False
    'oExcel.WindowState = XlWindowState.xlMinimized

    oDoc = oExcel.Workbooks.Open("C:handicap060926.xls") 'FileName is the full path and
    'name of the excel document.Ex:
    '"C:File.xls"
    'For i = 1 To oDoc.Worksheets.Count
    'oWorksheet = oDoc.Worksheets.Item(i) 'Loop through each worksheet

    End Sub
    End Class

    And this is the frist of 4 errors I get.

    Hello,
    i want to know that where the file (Excel Object Library) is located and also can MS Access also have a object Library, if yes then please note the location of the file. I want to access MS Access's Menus from VB.Net.
    Thanks in advance.
