export to excel using vb.net 2005

Hi,

I have attached the code in question. I'm trying to export the dataset into excel. I have used this code in the past and it seems to work well. The trouble I'm having is that the pc I am currently using to develop on does not have excel installed. I have the excel.exe file and have tried adding it to the references of the project but it says its not a valid coms object. How can I get this to work please?

Many Thanks
Lee
Dim xlApp As New Excel.Application
        Dim xlWB As Excel.Workbook = xlApp.Workbooks.Add
        Dim xlWS As Excel.Worksheet = xlWB.Worksheets.Add
        xlWS.Name = dt.TableName
        'add the headers
        For c As Integer = 0 To dt.Columns.Count - 1
            xlWS.Cells(1, c + 1).Value = dt.Columns(c).ColumnName
        Next
        'add the values
        For r As Integer = 0 To dt.Rows.Count - 1
            For c As Integer = 0 To dt.Columns.Count - 1
                xlWS.Cells(r + 2, c + 1).Value = dt.Rows(r)(c)
            Next
        Next
        xlWB.SaveAs(FilePath)
        xlWB.Close()
        xlApp.Quit()
        MsgBox("Export Complete", MsgBoxStyle.Information, "Complete")

You have a couple of workarounds if you don't have Excel fully installed:
1. instead of a real Excel file, create a .csv file which is only a text file in which you separate each field with a delimiter (like a coma or a tab). this format is recognized by Excel
2. Ues 3rd party products like http://www.aspose.com/categories/file-format-components/aspose.cells-for-.net-and-java/default.aspx

Without excel it wont work.
And you dont have to add a reference to the excel.exe, but to the Microsoft Excel Object Library.

Hi check this post I made today.
The last  code snippet is the best way to read to a excel file. Fast too!
You do need to file to run in excel..... excel.exe or something like.... XL5EN32.OLB
