As in Delphi 7 does not provide more than the corresponding version of dbexpress MySQL4.0 drive (although there is Borland's CodeCentral associated driver download, but I can not use, do not know whether it is my right way), so the use of Download MySQL 3.23.x before driving libmysql.dll, after downloading the libmysql.dll please put Delphi bin folder of the installation directory or system directory or a directory of your program, or dbexpress will not be able to find it (appear error: not load "libmysql.dll"). In addition, if the version of libmysql.dll not appear "invalid username / password" error.

I am now the emergence of this problem, I connected to a SQL-server2000, I downloaded a couple of MySQL 3.23.x driver libmysql.dll, but they appear invalid username / password, so that version right?

how to resolve, there is no better way to do this, please enlighten me master

there have been no similar errors, the driver may still not now! If dbexpmysql.dll (you can use delphi 7.1 upgrade package) version is correct, and will / MySQL / bin / libmysql.dll copied into delphi / bin directory, the connection should be able to succeed.
