Hello!
Recently, I was creating app that works with Mysql database. I think you also need to copy proper libmysql.dll connector library to your system directory (c:\windows\system32) / app exe directory. Also. For your information whether you noticed or not, in object inspector of mysql56 component there is a field dedicated for port if not mistaken. Try these out, if does not help, wud be happy to help. Since my program is running without problems now.
With respect,
Omirbay
