How should the brute-force database be supplemented?

From: FireFOX s BLOG

For example, I understand everything.

Program code:
Set Conn = Server. createObject ("ADODB. Connection ")
Conn. ConnectionString = "Provider = Microsoft. Jet. OLEDB.4.0; Data Source =" & Server. MapPath (AccessFile)
Conn. Open


Change
Program code:
On error resume next
Set Conn = Server. createObject ("ADODB. Connection ")
Conn. ConnectionString = "Provider = Microsoft. Jet. OLEDB.4.0; Data Source =" & Server. MapPath (AccessFile)
Conn. Open
If Err Then
Err. Clear
Set Conn = Nothing
Response. Write "database connection error. "
Response. End
End If
