Imports Microsoft.Office.Interop.Excel

Public Class TransferTool

Private Sub btn_PrevData_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btn_PrevData.Click
Dim wkbk As New Microsoft.Office.Interop.Excel.Workbook
wkbk.Open(Me.txt_ImportFile.Text)

strWrkBkNm = wkbk.Item(1).Name
wkbk.Close()
wkbk = Nothing

Gives an unspecified error, does anyone know why this will not run? Do I
need to install something?

Thanks,
Paula

Here is the error I receive:

Retrieving the COM class factory for component with CLSID
{00020819-0000-0000-C000-000000000046} failed due to the following error:
80040154.

Paula,

I think you need to change

Dim wkbk As New Microsoft.Office.Interop.Excel.Workbook
to
Dim wkbk As New Microsoft.Office.Interop.Excel.Workbooks

Note that this is plural "workbookS" not singular "workbook".

Just as a stylistic note, I would also change

Imports Microsoft.Office.Interop.Excel
to
Imports Excel = Microsoft.Office.Interop.Excel

Chip,

Thanks for your help.
If I add the s then I get an error telling me that the New keyword cannot be
used on an interface.

Then I take out the New and get this error at runtime:
Object reference not set to an instance of an object.

Any further advice?
Paula
