On what line of code does the error occur?

(PS: I edited your post and added [highlight=vb]your code goes in here[/highlight] - it makes code so much easier to read.)

[akhileshbc]

When you have finished with the database and wants to open a new connection, you have to close the connection first.

Example:

Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset

Set cn = New ADODB.Connection
cn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
      "Data Source= " & App.Path & "\database.mdb"
    cn.Open
Set rs = New ADODB.Recordset
    rs.Open "settings", cn, adOpenKeyset, adLockPessimistic, adCmdTable 

'// Here you will do the necessary coding.eg. searching, filling Listbox, etc.)

'// Now we have to close it
rs.close

'// now opening another table
    rs.Open "mytable", cn, adOpenKeyset, adLockPessimistic, adCmdTable 

'// rest of the code

'// now close all the connections and empty everything from the memory

rs.Close
cn.Close
Set rs = Nothing
Set cn = Nothing

...

If your error is happening at lines 11 or 30 then I would try putting rsgrade.Close at lines 25 and 44.
