hi
im unable to communication data in my application server and client, i am use windows 7,when i use windows XP is work well, can anyone help me please

my code like this
in application Server :
main:

#include <QtCore/QCoreApplication>
#include "server.h"
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
      MyServer server;
      server.listen(QHostAddress::Any, 4711);
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include "server.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
      MyServer server;
      server.listen(QHostAddress::Any, 4711);
    return a.exec();
}
