Quickly Add 10000 records to Access 2000

I am currently developing a VB6 program where, at one point, I need to add 10000 records to a table. Right now what I am doing is basically:

dim rs as new adodb.recordset

rs.Open "select * from TABLE1", sConnection, adOpenKeyset, adLockOptimistic

For i = 1 to 10000
   rs.addnew
   rs(0).value = "blah"
   rs(1).value = "blah blah"
   rs.update
Next i

This method is proving to be very very slow. Is there any other way to do this? Maybe some kind of batch import? Any suggestions/ideas will be welcome.

The batch addition of records is possible.
Approximately so:

Dim rstTitles As ADODB.Recordset
  Set rstTitles = New ADODB.Recordset
   rstTitles.CursorType = adOpenKeyset
   rstTitles.LockType = adLockBatchOptimistic
   rstTitles.Open "select * from TABLE1", sConnection, , , adCmdTable
   rstTitles.MoveFirst
   '
   Do Until rstTitles.EOF
        rstTitles(0).Value = "blah"
        rstTitles(1).Value = "blah blah"
   Loop
   If MsgBox("Save all changes?", vbYesNo) = vbYes Then
      rstTitles.UpdateBatch
   Else
      rstTitles.CancelBatch
   End If

End Sub

try this

Private Sub Command1_Click()
Dim rs As New ADODB.Recordset
sConnection = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\TestDb.mdb;Persist Security Info=False"
rs.Open "select * from TABLE1", sConnection, adOpenKeyset, adLockOptimistic

x = Timer
For i = 1 To 10000
  rs.AddNew Array("field1", "field2"), Array("blah", "blah blah")
  rs.Update
Next i

MsgBox (Timer - x)
End Sub

seeing your code it seems duplicate values is not a problem. in that cae you can try the following.

add one record manually
then run the following code

dim intCount as integer
dim strSQL as string
for intCount = 1 to 12
    strSQL = "insert into Table1 Select * from Table1"
    sconnection.execute strSQL
next intCount

by the time u comeout of for loop you should have about 16000 records in your table.

ibrahim-darahem, you are relatively new to this site so I would ask you to please read the guidelines on comments vs answers at the bottom of this page and on http://www.experts-exchange.com/jsp/cmtyQuestAnswer.jsp

It is not considered good practice to lock questions in this way, as this places these questions in the locked section and reduces the visibility of the question to other experts. It also tends to put pressure on the questioner to accept the proposed answer. In future, please do not post "answers" except in trivial questions which have one and only one answer such as what is 1+1. I know that is a bit simplistic but I am sure you get the idea.

If you continue to post answers, you will a) get some far more severe reactions from less tolerant experts, b) run the risk of your account being referred to customer services who may consider suspending your account.

Having said that I hope that you continue to contribute to this site and that your experience proves useful to many others in future.

Try this:

for i = 1 to 10000
  sConnection.Execute "INSERT INTO Table1(field1,field2) VALUES('blah','blah   blah')"
next

'If you want the no. i, to be used to identify the records, you can use it in the field values, here. Note that SQL queries execution is faster than recordsets usage.
