I am using a connection object from code and a DataEnvironment in a VB application
Set CON = New ADODB.Connection
CON.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\AA.MDB;Persist Security Info=False"
CON.Open
Set RS = New ADODB.Recordset
If RS.State = 1 Then RS.Close
RS.ActiveConnection = CON
RS.CursorType = adOpenKeyset
RS.LockType = adLockPessimistic
RS.CursorLocation = adUseClient
RS.Open "Select * from emp"
It gives a error at last line
error :- No value given for one or more required parameters.
Sometimes it gives error
Operation is not allowed when the object is closed.
