Hi,

I am trying to include UDP functionality in a Qt based GUI project. I am using VS2013 with VisualGDB. In the past I have not had any problems adding in includes for QLabel and other Qt libraries, but I am now! Below is the header and .cpp for a very basic object. VS2013 doessn’t report any intellisense erros, but when I go to build it says it can’t find the QUdpSocket or QHostAddress files. I have checked they are on both the destination machine and in my local cache.

#pragma once

#include <QMainWindow>
#include <QWidget>

#include <string>
#include <QUdpSocket>
#include <QHostAddress>

using namespace std;

class QUdpSocket;

class egdClass : public QWidget
{
Q_OBJECT
public:
egdClass();
~egdClass();
int send(std::string dataToGo);
QUdpSocket *udpSocket;
private:
int packetNumber;
QHostAddress destinationIP;
};

and the .cpp

#include “egdClass.h”
egdClass::egdClass()
{
udpSocket = new QUdpSocket(this);
packetNumber = 0;
destinationIP.setAddress(“192.168.1.11”);
}

egdClass::~egdClass()
{
delete udpSocket;
}

int egdClass::send(std::string dataToGo)
{
QByteArray datagram = dataToGo.c_str() + QByteArray::number(packetNumber);
udpSocket->writeDatagram(datagram.data(), datagram.size(), destinationIP, 45454);
}

Any ideas why I get this error on build?
