Terminating a console app

I have a small console app that will do some post install file & text proccessing. I need it to be self terminating & I need it to NOT show a console while running. I tried a.quit() & a.exit() to terminate, but neither one worked. I'm not sure how to supress the console window. The app will run on Win.

Any help is appreciated.

Thanx,

Ed

Code:

---

#include <QTextStream>
#include <QString>
#include <QFile>
 
QTextStream cout(stdout, QIODevice::WriteOnly);
QTextStream cerr(stderr, QIODevice::WriteOnly);
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QString str1, str2;
    QFile file("fixPath.txt");
    if(file.open(QIODevice::ReadOnly))
    {
        QTextStream in(&file);
        while (not in.atEnd())
        {
          str1 = in.readLine();
          cout << str1 << endl;
        }
        file.close();
      }
 
    return a.exec();
}

Suppressing the console window: Does

Code:

---

CONFIG -= console

in your Pro file do it for you? Of course, you have to have somewhere for your cout and cerr streams to go.

If you don't enter the event loop, i.e. don't call QCoreApplication::exec(), then the program just runs straight through to completion.

This is a common problem. You need to let the program enter the event loop.
To quit, you can use a timer with a singleshot for about 100ms and call the slot quit().

Thank you for the answers. I'm learning & relearning a little at a time.
