ASP Page error message

[pjha21]

Hi,

I am very new to asp. While studying about ASP, I found an online tutorial giving the below code. When I tried the same the error appears and I am not able to send my query from a form to database.

Can someone please help me in understanding the same.

Error:
ADODB.Connection error '800a0e79'

Operation is not allowed when the object is open.

/add_to_guestbook.asp, line 11

Code:
<%
'Dimension variables
Dim adoCon 'Holds the Database Connection Object
Dim rsAddComments 'Holds the recordset for the new record to be added
Dim strSQL 'Holds the SQL query to query the database
'Create an ADO connection object
Set adoCon = Server.CreateObject("ADODB.Connection")
'Set an active connection to the Connection object using a DSN-less connection
adoCon.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("guestbook.mdb")
'Set an active connection to the Connection object using DSN connection
adoCon.Open "DSN=guestbook"
'Create an ADO recordset object
Set rsAddComments = Server.CreateObject("ADODB.Recordset")
'Initialise the strSQL variable with an SQL statement to query the database
strSQL = "SELECT tblComments.Name, tblComments.Comments FROM tblComments;"
rsAddComments.CursorType = 2
'Set the cursor type we are using so we can navigate through the recordset
'Set the lock type so that the record is locked by ADO when it is updated
rsAddComments.LockType = 3
'Open the recordset with the SQL query
rsAddComments.Open strSQL, adoCon
'Tell the recordset we are adding a new record to it
rsAddComments.AddNew
'Add a new record to the recordset
rsAddComments.Fields("Name") = Request.Form("name")
rsAddComments.Fields("Comments") = Request.Form("comments")
'Write the updated recordset to the database
rsAddComments.Update
'Reset server objects
rsAddComments.Close
Set rsAddComments = Nothing
Set adoCon = Nothing
'Redirect to the guestbook.asp page
Response.Redirect "guestbook.asp"
%>

Any help will be highly appreciated.

Thanks

'Set an active connection to the Connection object using a DSN-less connection
adoCon.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("guestbook.mdb")

'Set an active connection to the Connection object using DSN connection
adoCon.Open "DSN=guestbook"


You are opening a connection, then attempting to open the connection again. adoCon.Open should only happen once.
