codice:
<WebMethod()> _
Public Function RestituisciDataReader(ByVal Strsql As String) As Odbc.OdbcDataReader
Conn.ConnectionString = Strconn
Conn.Open()
Dim res As Odbc.OdbcDataReader
Dim Com As New Odbc.OdbcCommand
Dim i As Integer
Com.CommandType = CommandType.Text
Com.CommandText = Strsql
Com.Connection = Conn
res = Com.ExecuteReader
res.Read()
