I use Zeos Database Objects to connect to MySQL with good result.
You can download from Torry http://www.torry.net/pages.php?id=547.

I installed the package, and I get an old version of libmysql.dll which makes dbExpress works, but I get invalid login name/password message, and I'm sure that I'm entering the correct user name and password.
I test it with local and remote database and I get the same error

Have you checked for case-sensitivity on the username / password ?
And also if the user is written like user@localhost or user@mydomain.com (those users has to have access rights in MySQL as well)
MySQL recoginizes the user as user@....

Check this manual http://www.mysql.com/documentation/mysql/bychapter/manual_MySQL_Database_Administration.html#User_Account_Management
for managing user accounts and privilages.

shell> mysql --user=root mysql
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP
    ->     ON bankaccount.*
    ->     TO 'custom'@'localhost'
    ->     IDENTIFIED BY 'obscure';
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP
    ->     ON expenses.*
    ->     TO 'custom'@'whitehouse.gov'
    ->     IDENTIFIED BY 'obscure';
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP
    ->     ON customer.*
    ->     TO 'custom'@'server.domain'
    ->     IDENTIFIED BY 'obscure';
The three accounts can be used as follows:

The first account can access the bankaccount database, but only from the local host.
The second account can access the expenses database, but only from the host whitehouse.gov.
The third account can access the customer database, but only from the host server.domain.
