MySql Driver not loaded

[eekhoorn12]

Hey all

I have a problem with mysql connection. When i try to connect to a mysql database i get the error "driver not loaded".

I use the following code:

#include <QApplication>
#include <QLabel>
#include <QSqlDatabase>
#include <QSqlError>
#include <QMessageBox>
 
bool createConnection()
{
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setHostName("***********");
    db.setPort(3306);
    db.setDatabaseName("wachtrij");
    db.setUserName("root");
    db.setPassword("");
    if (!db.open()) {
        QMessageBox::critical(0, QObject::tr("Database Error"),
                              db.lastError().text());
        return false;
    }
    return true;
}
 
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel;
    if(createConnection() != false)
    {
	    label->setText("Database connected");
	}
	else
	{
		label->setText("Database failed to connect");
	}
    label->show();
    return app.exec();
 
}

#include <QApplication>
#include <QLabel>
#include <QSqlDatabase>
#include <QSqlError>
#include <QMessageBox>

bool createConnection()
{
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setHostName("***********");
    db.setPort(3306);
    db.setDatabaseName("wachtrij");
    db.setUserName("root");
    db.setPassword("");
    if (!db.open()) {
        QMessageBox::critical(0, QObject::tr("Database Error"),
                              db.lastError().text());
        return false;
    }
    return true;
}


int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel;
    if(createConnection() != false)
    {
	    label->setText("Database connected");
	}
	else
	{
		label->setText("Database failed to connect");
	}
    label->show();
    return app.exec();
    
}

To copy to clipboard, switch view to plain text mode 

I had a problem with compiling the code but that is solved.
I followed these instructions: http://wiki.qtcentre.org/index.php?t...ws_using_MinGW
and when i want to compile i ad QT += sql to the .pro file

I've searched trough this forum and other forums but couldn't find the solution.

I am using Qt 4.3 and mingw on windows xp

I hope you can help me.
