Hi

Perhaps this have nothing with the mysql, but yes if you compiled your
application in release or debug mode.

If you compile as debug mode you've use all qt dlls with 'd'. qtcore4d.dll

I think that this problem can be this.

I've problems similar problems when I compile application in release mode under window$

use Dependency Walker to check what dlls do you need

I used release mode..

I checked out with dependency walker.. I don't know what do solver the error..

I attached the screen shot image of dependency walker.

Use debug mode! Do the test and see what happens.
I think that is not going to happen in this mode.

man, where do you have that MySQL database you want to connect? If it is not on the same machine as application runs than "localhost" is not a valid host

[addu]

How do i solve this issue ?
i tried with my system ip address instead of localhost ..

Please help me

Thanks

a) is your database at the same PC your application is supposed to run?
b) is your mysql daemon (or however that is called in win) up and running
c) recheck path to your database

I think your database driver should be in a subdirectory:

sqldrivers/qsqlmysql4.dll

you should only require:

mingwm10.dll
QtCore4.dll
QtGui4.dll
QtSql4.dll

as well as the appropriate database driver already mentioned in the sqldrivers subdirectory for a standard sql gui program, all these should be placed in the same directory as the executable program.
