首先建立一个MyThread的基类，提供基本的功能：

#pragma once
#include <Windows.h>

class MyThread
{
public:
	MyThread();
	virtual ~MyThread();

	bool Start();
	bool Join();
	bool Detach();
	DWORD Self();

private:
	static DWORD WINAPI Run(PVOID pObj);
	virtual DWORD RumImpl() = 0;

protected:
	static bool m_running;
	static bool m_detached;

private:
	DWORD  m_tid;
	HANDLE m_HANDLE;
};

#include "MyThread.h"
#include <cstdio>
#include <cstdlib>

bool MyThread::m_running = false;
bool MyThread::m_detached = false;

MyThread::MyThread()
: m_tid(0)
, m_HANDLE(NULL)
{

}

MyThread::~MyThread()
{
	if (m_running)
	{
		WaitForSingleObject(m_HANDLE, INFINITE);
		m_running = false;
	}

	if (NULL != m_HANDLE)
	{
		CloseHandle(m_HANDLE);
	}
}

bool MyThread::Start()
{
	if (NULL != m_HANDLE)
	{
		printf("Thread opened.\n");
		return false;
	}

	m_HANDLE = CreateThread(NULL, 0, Run, this, 0, &m_tid);
	if (NULL == m_HANDLE)
	{
		printf("CreateThread Error.\n");
		return false;
	}
	return true;
}

bool MyThread::Join()
{
	WaitForSingleObject(m_HANDLE, INFINITE);
	return true;
}

bool MyThread::Detach()
{
	return CloseHandle(m_HANDLE);
}

DWORD MyThread::Self()
{
	return m_tid;
}

DWORD WINAPI MyThread::Run( PVOID pObj )
{
	m_running = true;
	MyThread* lpThread = (MyThread*)pObj;
	return lpThread->RumImpl();
}

然后，定制自己的AllenThread：

#pragma once
#include "mythread.h"

class AllenThread :
	public MyThread
{
public:
	AllenThread();
	virtual ~AllenThread();

	virtual DWORD RumImpl();
};

#include "AllenThread.h"

#include <cstdio>

AllenThread::AllenThread(void)
{
}

AllenThread::~AllenThread(void)
{
}

DWORD AllenThread::RumImpl()
{
	printf("Yes.It's Allen's Thread.\n");
	m_running = false;
	return 0;
}

写的还很粗糙，之后慢慢完善。
