Problem using the if...else structure in main.cpp

ommz

Im trying to use the if else structure to control which form is shown before the main window. The app first checks if a file named add.txt is present then shows thecorrect form. Here's my code:

@
//a continuation of the main.cpp

if (0 == access ("C:/Microsoft/add.txt",0))

(MainWindow z;
z.show();
}

else {
window2 y;
y.show();
}

return a.exec();
}
@

However, the window just blinks and runs in the background with no UI. How do I make it run correctly by showing the UI??

[EDIT: code formatting, please wrap in @-tags, Volker]

Both z and y are declared inside the block where you call show on them. Once you leave that block they are going out and are destroyed.

I would rewrite it as something like:
@
//a continuation of the main.cpp

MainWindow *z = 0;
window2 *y = 0;

if (0 == access ("C:/Microsoft/add.txt",0))
z = new MainWindow();
z->show();
} else {
y = new window2();
y->show();
}

return a.exec();
}
