compare two tables using this module?

P: n/a
In the article "Delete Duplicate Records From Access Tables"
By Danny Lesandrini writes the following:

This final suggestion is the most flexible and accurate. Given any
table, it generates a recordset of appropriate fields (excluding memo
and binary image fields) and dynamically loops through the fields'
collection to perform the recordset compare.

In this example, two recordsets are used, one being a clone of the
other. When a duplicate is found, it is deleted from the first
recordset and the next record is examined. When it has determined that
the records do not match, both recordsets are advanced. The code for
this solution is shown below. Copy and paste it into an Access module
and try it.
Sub DeleteDuplicateRecords(strTableName As String)
' Deletes exact duplicates from the specified table.
' No user confirmation is required. Use with caution.
Dim rst As DAO.Recordset
Dim rst2 As DAO.Recordset
Dim tdf As DAO.TableDef
Dim fld As DAO.Field
Dim strSQL As String
Dim varBookmark As Variant

Set tdf = DBEngine(0)(0).TableDefs(strTableName)
strSQL = "SELECT * FROM " & strTableName & " ORDER BY "
' Build a sort string to make sure duplicate records are
' adjacent. Can't sort on OLE or Memo fields,though.
For Each fld In tdf.Fields
If (fld.Type <> dbMemo) And _
<> dbLongBinary) Then
strSQL = strSQL & fld.Name & ", "
End If
Next fld
' Remove the extra comma and space from the SQL
strSQL = Left(strSQL, Len(strSQL) - 2)
Set tdf = Nothing

Set rst = CurrentDb.OpenRecordset(strSQL)
Set rst2 = rst.Clone
Do Until rst.EOF
varBookmark = rst.Bookmark
For Each fld In rst.Fields
If fld.Value <> rst2.Fields(fld.Name).Value Then
GoTo NextRecord
End If
Next fld
GoTo SkipBookmark
rst2.Bookmark = varBookmark
End Sub

How do I put this into a access project so I can compare two tables?
