Dim Content

Dim Strings
 Strings = Len(Content)
Dim Steps
 Steps = 1
Dim OnceCut
 OnceCut = 5
Dim i,CurrentStr
For i = 1 To Strings Step OnceCut
 CurrentStr = Mid(Content,Steps,OnceCut)
 Set Rs = Server.CreateObject("Adodb.RecordSet")
  SQL = ("SELECT Content FROM [News] WHERE (ID IS NULL)")
  Conn.Open Rs,SQL,1,3
  Rs.Addnew
  Rs(0) = CurrentStr
  Rs.Update
  Rs.Close
 Set Rs = Nothing
 Steps = Steps + OnceCut
