Help in OOP

Hello Everyone ,
I'am new to OOP and QT and i'm trying to write a simple chat program (client , server) with winsockets.
I Have an error which i don't seem to understand :

this is my code so far :

Code:

#include "pmessenger.h"
#include "ui_pmessenger.h"
SOCKET s;
PMessenger::PMessenger(QWidget *parent) : QMainWindow(parent), ui(new Ui::PMessenger)
{
    ui->setupUi(this);
    WSADATA wsadata;
    if(WSAStartup(MAKEWORD(2,2),&wsadata)!=0)
    {
         QMessageBox::critical(this,"Error","Winsock Startup Failed",0,0);
         this->close();
    }
    s = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
    if(s==INVALID_SOCKET)
    {
          QMessageBox::critical(this,"Error","Socket Creation Faild",0,0);
          WSACleanup();
          this->close();
    }
    SOCKADDR_IN server;
    server.sin_family = AF_INET;
    server.sin_port = htons(7676);
    server.sin_addr.s_addr = inet_addr("my ip is here :D");
    if(::connect(s,(sockaddr*)&server,sizeof(server))!=0)
    {
          QMessageBox::critical(this,"Error","Can't Connect",0,0);
          WSACleanup();
          this->close();
    }
    CreateThread(NULL,0,ServerMsgThread,(LPVOID)s,0,0); // the problem is in this line :(
}

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

void PMessenger::on_pushButton_clicked()
{
    QString msg = ui->plainTextEdit_2->toPlainText();
    send(s,(const char *)msg.data(),4096,0);
}

void PMessenger::AddMessege(char msg[4096])
{
    ui->plainTextEdit->appendPlainText(msg);
}

DWORD PMessenger::ServerMsgThread(LPVOID pParam)
{
      SOCKET Cs = (SOCKET) pParam;
      char data[4096];
      while(1)
      {
           if(recv(Cs,data,1024,0)>0)
               AddMessege(data);
      }
      return 0;
}

I Get the following error :

..\PMessenger\pmessenger.cpp:32: error: argument of type 'DWORD (PMessenger:: )(void*)' does not match 'DWORD (*)(void*)'

Any help would be greatly appreciated (i really don't want to move to wxWidgets because of that error)

Thanks
