Thanks sir..here's another problem:err:..i'm trying to use the report viewer ,i also made a design for the report,then i clicked 'add new data source',chose the database,but when im choosing the database objects an error appeared- something like this sir-Could not get column information for database object named ('my database' name',table name'). Is there a conflict on my ODBC 5.3 ansi driver?I also installed the mysql-connector-net 6.9.8..
