ConnDB è in un'altro file così strutturato:

*********************************
using System;
using System.Data.Odbc;

namespace Connessione

public class ConnDB
{
private string sStringaConn;

public void OpenConnDB(string sDataBase){
sStringaConn = "DRIVER={Gupta SQLBase};DataBase="+sDataBase+";Uid=pippo;Pwd=pipp o;";
Conn = new OdbcConnection(sStringaConn);
Conn.Open();
}
public void CloseConnDB(){
Conn.Close();
}
public void SQL_Insert(string sInsert){
OdbcCommand myInsert = new OdbcCommand(sInsert,Conn);
myInsert.Prepare();
myInsert.ExecuteNonQuery();
}
public void SQL_Update(string sUpdate){
