มีปัญหาเรื่องการสร้างรายงานด้วย Crystal Report + VB2008

		strSQL.Append(" SELECT a.CustomerID,a.Name,a.Email,a.Budget, ");
		strSQL.Append(" b.CountryName,c.Date,c.Used ");
		strSQL.Append(" FROM customer a  ");
		strSQL.Append(" LEFT JOIN country b ON a.CountryCode =  b.CountryCode ");
		strSQL.Append(" LEFT JOIN audit c ON a.CustomerID = c.CustomerID ");
		strSQL.Append(" WHERE a.CustomerID = '" + this.txtCustomerID.Text + "' ");

		objConn.ConnectionString = strConnString;
		var _with1 = objCmd;
		_with1.Connection = objConn;
		_with1.CommandText = strSQL.ToString();
		_with1.CommandType = CommandType.Text;
		dtAdapter.SelectCommand = objCmd;

		dtAdapter.Fill(ds, "myDataReport");
		dt = ds.Tables[0];
