救命啊，error C2440: 'type cast': cannot convert from '' to 'void (__stdcall *)

我定义了一个类,需要在类中使用定时器,由于没有使用MFC,因此使用的windows底层接口。



#include <winsock2.h>

#include <windows.h>

#include <queue>

#include <stdio.h>



using namespace std;



class CVCTComTask  

{

public:

	int AudmComTask();

public:

	HANDLE			m_MsgHandle;

	HANDLE			m_tmHandle;

	int			m_TpaRecvTimer;

	int			m_TpaHandShakeTimer;

	int			m_TpaSendAddrTimer;

public:

	DWORD WINAPI winVctMsgTask(LPVOID lpParameter);

	int TimerTask();

	int RecvTimer();	

	int SendTimer();

	int HartTimer();

        int ReceiveMessage(MESSAGE& NewMsg);

};

//CVCTComTask.cpp--------------------------------------

int CVCTComTask::AudmComTask()

{

	m_MsgHandle = CreateThread(NULL, 0,(LPTHREAD_START_ROUTINE )VctMsgTask,NULL, 0, NULL);

	m_tmHandle = CreateThread(NULL, 0,(LPTHREAD_START_ROUTINE )TimerTask,NULL, 0, NULL);

	return 1;

}



int  CVCTComTask::VctMsgTask()

{

	MESSAGE		stMsg;

	int flag = 0;

	while (1)

	{

		flag = 0;

		flag = ReceiveMessage(stMsg);

		if (1 == flag)

		{

			continue;

		}

		

		//processMsg(stMsg);

		memset(&stMsg, 0, sizeof(stMsg));

		Sleep(1);

	}

	return 0;

	return 1;

}



int CVCTComTask::TimerTask()

{

	

	MSG			msg;

	printf("Start Get Timer!!!\n");

	/* 收包 定时器*/

	

	m_TpaRecvTimer = SetTimer(NULL, 1, 50, (TIMERPROC)RecvTimer);

	

	m_TpaSendAddrTimer = SetTimer(NULL, 2, 10000, (TIMERPROC)SendTimer);

	while(GetMessage(&msg,NULL,0,0))

	{

		if (1 == m_hflag)

		{

			m_TpaHandShakeTimer= SetTimer(NULL,3,500,(TIMERPROC)HartTimer);	

			m_hflag = 0;

		}

		TranslateMessage(&msg);

		DispatchMessage(&msg);

		Sleep(1);

	}

	return 1;

}

出现了5个这样的错误。
error C2440: 'type cast' : cannot convert from '' to 'void (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,unsigned long)'
程序中希望实现创建两个线程，一个用于接收定时器消息，一个用于接收队列消息。
但在线程的创建以及定时器的启动时出现错误。
