problem in client and server model of tcp in qt

hi,

i like to implement simple client -server model of qt. but unfortunately i dint get proper output. its totally runtime error. please help me to find out..

here my server code which will receive the output once connected with client :

code:

#include "widget.h"
#include "ui_widget.h"
#include "QtNetwork/qabstractsocket.h"
#include "QtNetwork/qtcpserver.h"
#include "QtNetwork/qtcpsocket.h"
#include "QtNetwork/QHostAddress"
#include "QMessageBox"
#include "QDebug"
#include "QDataStream"
#include "stdio.h"
Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{
ui->setupUi(this);
int s;
serversocket=new QTcpServer();


client=new QTcpSocket();
serversocket->listen(QHostAddress::Any,5639);

QObject::connect(serversocket,SIGNAL(newConnection ()),this,SLOT(memberofserver()));

}

Widget::~Widget()
{
delete ui;
}


void Widget::memberofserver()
{

QTcpSocket *client = serversocket->nextPendingConnection();
QObject::connect(client,SIGNAL(disconnected()),cli ent,SLOT(deleteLater()));
QDataStream in(client);
in.setVersion(QDataStream::Qt_4_0);
QString data;
in >> data;
ui->text1->setText(data);
}


here my client code which will send data to server once it got connected :

code :

#include "widget.h"
#include "ui_widget.h"
#include "QMessageBox"
#include "QAbstractSocket"
#include "QTcpSocket"

Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{

ui->setupUi(this);

client1=new QTcpSocket(this);
client1->connectToHost("ipaddr...",5639);
if(client1->state()==QAbstractSocket::ConnectedState)
QMessageBox::information(this,tr("client"),tr("suc cessfullyconnected"));
else
QMessageBox::information(this,tr("server"),tr("uns uccessfulcompletion"));

client1->write("heysuper",20);
}

Widget::~Widget()
{
delete ui;
}



please help me to find out soon

thanks in advance,
shakthi

Code:

---

//In server
serversocket = new QTcpServer(this); // set a parent to server (good practice)
//client = new QTcpSocket(); //memory leak
 
//In client
if(client1->state() == QAbstractSocket::ConnectedState)
//you cannot expect to establish connection immediatly, either use waitForConnected() to wait or connect to connected() signal and then write data
