uhm yes i guess i use a function in a class to test the connection but after QApplication

int main(int argc, char *argv[])
{
 
    QApplication a(argc, argv);
	Q_INIT_RESOURCE(resources);
    CMain w;
 
   if( !w.createConnection() )
		return 1;
    w.show();
    a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
 
}

int main(int argc, char *argv[])
{
	
    QApplication a(argc, argv);
	Q_INIT_RESOURCE(resources);
    CMain w;
	
   if( !w.createConnection() )
		return 1;
    w.show();
    a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
    
}

QCoreApplication is responsible for plugin loading, so if you won't create QCoreApplication or QApplication plugins won't be accessible.

Have you seen any references to MySQL DLLs in Dependency Walker?

Yes i got all references in my release directory and the mysql dll but no luck

QCoreApplication is responsible for plugin loading, so if you won't create QCoreApplication or QApplication plugins won't be accessible.

so i must use QCoreApplication instead of QApplication?

QApplication inherits QCoreApplication.

ok i made the plugin through make and by configure but no success loading it by Qt any ideas?

[chaosgeorge]

Oh my wtf hmfs this at least!!!!!!!!!!!!!! i got it!!!!!!!!!!! the problem was... uhm i dont know what it was but i reinstalled mysql, "mingw-ized" the libs "make-ized" the libs to build the plugin "make-installed" the plugin and taratatannn Qt loaded the driver !!!!!! the last option is what worked at least damn o well now i have to solve connection problems to my remote server LOL thanks everyone

uhm wtf uhm it looks like it only works in the visual studio command prompt environment in qt command prompt it loads the driver but i get the driver not loaded error right after any ideas? by the way i used nmake instead of make

[wysota]

You are missing some environment variables (from MySQL?) and you probably mixed up two different builds - MSVC (nmake) one and MinGW (make) one.

[chaosgeorge]

Uhm what environment variables could be? and doesn't matter how i build the program (nmake or make) it just works from any cmd window but qt's cmd window, do i have to add env vars to qt's cmd? how?
