When I'm calling my INSERT sp, I get the following error from VB6 sp4 program:

Run-time error '-214717867'
[Microsoft][ODBC Sql Server Driver]Optional Feature not implemented.

Here's my code:

Dim lngRecordsAffected
Dim objCommand As New Command

objCommand.ActiveConnection = gstrConnectString
objCommand.CommandText = "sp_insert_ListOrder"
objCommand.CommandType = adCmdStoredProc

objCommand.Parameters.Append _
objCommand.CreateParameter("MailingOrderID", adInteger, _
adParamInput, , lngMailingOrderID)
objCommand.Parameters.Append _
objCommand.CreateParameter("ListID", adInteger, _
adParamInput, , lngListID)

etc...

objCommand.Execute lngRecordsAffected

The error is called on the last line. TIA.
