Permission denied error during linking

[bashamehboob]

hai ,

what's my problem is close one form and open another after some time interval.
i have written following code as follows.



#include "ui_Screen3.h"
#include "ui_Screen5.h"
#include <QApplication>
#include <QObject>
#include <QTableWidgetItem>
#include <QTableWidget>
#include <QTimer>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWidget *window = new QWidget;
QWidget *window1 = new QWidget;
QTimer *timer = new QTimer;
Ui::Form1 ui;
Ui::Form ui1;
ui.setupUi(window);
ui1.setupUi(window1);

window1->show();


QObject::connect(timer, SIGNAL(timeout()), window1, SLOT(hide()));
timer->start(1000);
QObject::connect(window1, SIGNAL(hide()), window, SLOT(show()));
return app.exec();
}


i was gettting following error

The error says you have a permission problem. Check that you don't already have a release\new.exe file, and that if you do, it is not read-only.

Make sure that your application isn't running when you link a new version.
