1. You need to create an Excel Application object e.g.
Dim xlApp As Excel.Application
Set xlApp = CreateObject("Excel.Application")
2. To open a particular workbook, you need to use the Open
method of the Workbooks Collection e.g.
Dim xlBook As Excel.Workbook
Set xlBook = xlApp.Workbooks.Open {filename}
The {filename} needs to be replaced with the file of your
choice with the full path.
Don't forget to include the Excel Object librarry wthin the
References.
Hope This Helps
