But you can access this value with a recordset object (ADO). You will be
incurring in extra work because SQL Server has to parse and create an
execution plan for the statement every time you use it. Also, the interface
(ADO) has to create a recordset because you are returning the value using a
SELECT statement.

dim oRst as adodb.recordset
dim oConn as adodb.connection

set oConn = new adodb.connection

' set connection properties and open it
...

strSQL = "INSERT INTO dbo.CompanyData (CompanyName, Address1)
VALUES (" & strCompanyName & ", " & strAddress1 & ") "
strSQL = strSQL & "SELECT SCOPE_IDENTITY() as newIdent"

set oRst = oConn.execute strSQL
...

Here are a couple of articles where to read about ADO Best Practices.
