How do I populate ADO recordset with no connection.

I am using VBasic v6, ADO, and Access.

I need to pass a data record to an existing subroutine, that
I did not write.

The subroutine expects the record in the form of a
recordset object, with a single record.

I have my field values that have been computed outside of
any database.  A database with the proper table does not
exist and no connection.  I need to get my values into a
Recordset object.  I want to do something like the following.

-----

    dim RecSet as ADODB.Recordset
    dim name_list(1) as String
    dim value_list(1) as String

    name_list(0) = "Field_0"
    name_list(1) = "Field_1"
    value_list(0) = "val_0"
    value_list(1) = "val_1"

    Set RecSet = new ADODB.Recordset
    RecSet.CursorLocation = adUseClient
    Call RecSet.Open(, , adOpenStatic, adLockBatchOptimistic)
    Call RecSet.AddNew(name_list, value_list)

Alternately, instead of the "AddNew" method I could do something
like:

    ' Declare and initialize an ADODB.Field object
    Dim field_0 as ADODB.Field
    Set field_0 = new ADODB.Field
    ' Initialize the name and value properties of field_0
    Call RecSet.Fields.Append field_0

-----

This does not work.  The following Open fails.

    Call RecSet.Open(, , adOpenStatic, adLockBatchOptimistic)

Instead of adOpenStatic, I have also tried adOpenForwardOnly.

The documentation for the Open method says that Source (1st parm)
and ActiveConnection (2nd parm) are optional.  But Open() still
throws an error.  The error message says that I need a connection.
If, experimentally, I give a valid connection to an irrelevant
database, then I get an error about the missing source (first parm).

And AddNew throws an error, if I try to execute AddNew without
the Open.


So the question is, "How do I populate a recordset with data when
I have no connection to a database?"

This will work:

Private Sub Command1_Click()
Dim RecSet As ADODB.Recordset

   Set RecSet = New ADODB.Recordset
   RecSet.CursorLocation = adUseClient
   RecSet.CursorType = adOpenStatic
   RecSet.LockType = adLockBatchOptimistic
   RecSet.Fields.Append "Field_0", adVarChar, 50
   RecSet.Fields.Append "Field_1", adVarChar, 50
   RecSet.Open
   Call RecSet.AddNew(Array("Field_0", "Field_1"), Array("val_0", "val_1"))

    MsgBox RecSet.RecordCount
End Sub
