       for(int i = 0; i < 10; i++)
       {
           // Insert column 1 value into each error.
           table.Rows[i].RowError = "ERROR: " 
               + table.Rows[i][1];
       }
       // Get the DataSet for the table, and test it for errors.
       DataSet dataSet = table.DataSet;
       TestForErrors(dataSet);
   }

   private void TestForErrors(DataSet dataSet)
   {
       // Test for errors. If DataSet has errors, test each table.
       if(dataSet.HasErrors)
       {
           foreach(DataTable tempDataTable in dataSet.Tables)
           {
               // If the table has errors, then print them.
               if(tempDataTable.HasErrors)

           }
           // Refresh the DataGrid to see the error-marked rows.
           dataGrid1.Refresh();

   private void PrintRowErrs(DataTable table)

           }
       }
   }

    If dataSet.HasErrors
        Dim tempDataTable As DataTable
        For Each tempDataTable in dataSet.Tables
            ' If the table has errors, then print them.
            If(tempDataTable.HasErrors) Then
