The following command:

    Dim ef1 As New ExcelFile

gives me the error:

    User defined type not defined.

I added the excel library 8.0.  It worked on a different computer using the 9.0 library.  should I be adding more components or references? and what is the different between 8.0 and 9.0?
Thanks

This type doesn't exist in the 8.0 version!

try
dim xl As Excel.Application
xl.Workbooks.Open "PathAndFileNameAsString"
this should offer up most properties and methods used.

The way glenrichmond put it is the way to do it, but you have to declare it like this:
Dim xl as New Excel.Application

If you don't you'd have to set the xl variable later on, which is not what you'd want.

So the proper way to declare an excel file that will work in both excel library 8.0 and 9.0 is this?:

dim xl As New Excel.Application
xl.Workbooks.Open "PathFileNameAsString"

if i don't put "new" will it open an existing excel file or it is declaring the variable xl as a new excel object?

where can i find a list of these methods you mention?
ie.  xl.Cells(R, C).Value =...

If you don't put the "New", you need a syntax like this:
dim xl As Excel.Application
set xl = new Excel.Application
-or-
set xl=CreateObject("Excel.Application")

Try not to put the New on the declaration line.

"where can i find a list of these methods you mention? "
You may look the help file but an easy way I find command of Excel, Word, ... is to record macros!

I am sorry. I wasn't sure which one to choose.

I knew how to declare an excel object both ways.  I just didn't know exactly what was happening and what was the difference between both types of declarations.  I guess the answer I was looking for was an understanding of the commands and what was the difference of the 8.0 and 9.0

I hope there is no hard feelings.
