给你一个封装好的 class, 转到 c++builder 下很容易
#pragma once
#include "Delegate.h"
class CExThread
{
CWinThread* m_pThread;
BOOL m_bThreadAlive;
BOOL m_bStopThread;
static UINT Start(LPVOID pParam);
public:
CDelegate m_Delegate;
CExThread(void);
~CExThread(void);
bool Run();
void Stop();
};
#include "stdafx.h"
#include "exthread.h"
CExThread::CExThread(void)
{
m_pThread = NULL;
m_bThreadAlive = FALSE;

}

}

}
