setup MS Excel globally?

[dtvonly]

Hi. In VB6 I can declare excel components globally in a VB module then call it in the Form:

Public Sub Setup_MSEXCEL()
    Set xlApp = New Excel.Application
    Set xlWB = xlApp.Workbooks.Add
    Set xlWS = xlWB.Worksheets("sheet1")

In VB.NET I tried this:

Dim XL as Excel.Application
Dim WB as Excel.Workbook
Dim Sheet as Excel.Worksheet

Should this be in a public class or a module?

I tested my code by placing one button on the form to CREATE_EXCEL.
This caused an error since the private button routine did not "see" that Excel does exist.

How do I setup MS Excel globally so that any private sub can access it? By the way, I had already added the reference to Excel library.

If possible, please attach short code.
