Once you've selected Event Procedure, click on the 3 dots next to the dropdown box, and you should appear in the Form's Code window, place the cursor below the line for Private Sub Command1_Click() and above the Line for End Sub as shown below
Private Sub Command0_Click()
' cursor should be here
End Sub
Then add the following code depending on which version of Access you have
(Be sure to change the name of the Table from TableNameGoesHere to the actual name of your table)
For Access 97
Dim db As DAO.database, rst As DAO.Recordset
Dim intI As Integer
Set db = CurrentDb
Set rst = db.OpenRecordset("TableNameGoesHere"

With rst
For intI = 1 To 10000
rst.AddNew
rst.Update
Next intI
End With
MsgBox "Done"
For Access 2000
Dim rst As New ADODB.Recordset
Dim intI As Integer
rst.Open "TableNameGoesHere", CurrentProject.Connection, _
adOpenKeyset, adLockOptimistic
With rst
For intI = 1 To 10000
rst.AddNew
rst.Update
Next intI
End With
MsgBox "Done"
Then close the Code window, open the form and click on the command button.
