SQLITE database problem

Hi,

I am having a problem with SQLITE.

[CODE]
if (QSqlDatabase::isDriverAvailable("QSQLITE")) // this works fine, returns true
{
db = QSqlDatabase::addDatabase("QSQLITE"); //but this statement does not work
QMessageBox::information(0, tr("Test "), "It works!"); // never reached this statement
}
[/CODE]

When the program executes the addDatabase, the simulator hangs then crashes. It always exit with the code -1073741819.

I have included Qt += sql in pro file and included the whole QtSql package in my file. I am using Qt 4.7.3

How do I go about this?

Thank you very much

I am sure that the program enters the if statement. I have run some tests that verified that QSqlDatabase::isDriverAvailable("QSQLITE") returns true

That's apparently a Windows access violation. Does the object "db" exist? How is it declared?

You are right. "db" was not initialized properly. Thanks!
