I have a C# application runing on my PC and Mysql server on the web. When I am using the Mysqldirect.net and connect it to my local host ther is no problem. but when I am trying to connect my application to remote mysql server on the web. I get an error message like:
access denied for user:"[email protected]'(using password:YES) . I am sure I have a right user name and password , I dont know why i get such error. If anyone know please let me know.
many thanks.

Check if you can connect to database server using standard console client (mysql.exe). If you can do it send us connection parameters you've specified in command-line.
