本文展示了一个使用C++在Windows环境下创建并控制线程的例子。通过创建两个工作线程，演示了如何设置线程优先级、挂起及恢复线程运行等操作。

#include "iostream"
#include "windows.h"
using namespace std;

class CWorkerThread{
public:
	CWorkerThread(LPCTSTR m_szName):m_szName(m_szName),m_hThread(INVALID_HANDLE_VALUE){
		m_hThread=CreateThread(
			NULL,
			0,
			ThreadProc,
			reinterpret_cast<LPVOID>(this),
			0,
			NULL
			);
	}

	virtual ~CWorkerThread(){CloseHandle(m_hThread);}

	virtual void WaitForCompletion(){
		WaitForSingleObject(m_hThread,INFINITE);
	}

	virtual void SetPriority(int nPriority){
		SetThreadPriority(m_hThread,nPriority);	
	}

	virtual void Suspend(){
		SuspendThread(m_hThread);
	}

	virtual void Resume(){
		ResumeThread(m_hThread);
	}

protected:
	static DWORD WINAPI ThreadProc(LPVOID lpParam){
		CWorkerThread *pThis=
			reinterpret_cast<CWorkerThread*>(lpParam);

		pThis->DoStuff();
		return (0);
	}

	virtual void DoStuff(){
		for(int n=0;n<10;n++){
			cout<<"Thread"<<m_szName<<"ID:"<<GetCurrentThreadId()<<",count"<<n<<endl;
		}
	}

protected:
	HANDLE m_hThread;
	LPCTSTR m_szName;
};

void main(){
	CWorkerThread wtA("A");
	CWorkerThread wtB("B");

	wtA.SetPriority(THREAD_PRIORITY_LOWEST);

	wtB.Suspend();

	wtA.WaitForCompletion();
	wtB.Resume();
	wtB.WaitForCompletion();

	cout<<"Both threads complete."<<endl;

	getchar();
}
