Problem with reading in data from a QTCPSocket

[Denarius]

Hello,
I'm getting data from a server in the format:
char* identifier
double timestamp
char* message
double n1
double n2
double n3

When I try to read it, i get 0 bytes.

This is my piece of code:

void MyClass::ReadData{
	while(m_TcpSocket->bytesAvailable() > 0){
		blockSize = m_TcpSocket->bytesAvailable();
		QDataStream in(m_TcpSocket);
		in.setVersion(QDataStream::Qt_4_0);
 
		QVariant value;
		QString package;
		char* id;
		double time;
		char* message;
		double n1,n2,n3;
 
		in >> id;
		in >> time;
		in >> message;
		in >> n1 >> n2 >> n3;
 
		package = id;
		value = time;
		package.append(value.toString());
 
		emit messageReady(package);
	}
}

void MyClass::ReadData{
	while(m_TcpSocket->bytesAvailable() > 0){
		blockSize = m_TcpSocket->bytesAvailable();
		QDataStream in(m_TcpSocket);
		in.setVersion(QDataStream::Qt_4_0);

		QVariant value;
		QString package;
		char* id;
		double time;
		char* message;
		double n1,n2,n3;

		in >> id;
		in >> time;
		in >> message;
		in >> n1 >> n2 >> n3;

		package = id;
		value = time;
		package.append(value.toString());

		emit messageReady(package);
	}
}

messageReady just appends the string into a textfield/browserfield.
