Hm, the error means normaly that libmysql.dll could not be found. So is libmysql.dll in the same directory as QtCore4.dll and also is libmysql.dll the library you used to build qsqlmysql4.dll?

libmysql.dll is in MySQL's lib, and I copy to my program file.
libmysql.dll and qsqlmysql4.dll must copy to sqldrivers file??
And now libmysql.dll in the same directory as QtCore4.dll, but there also has the problem.
I don't know what you said.
