VC++实现多线程的调度和处理

核心提示：计数线程::Run() 函数的重载代码为：int CCounterThread::Run(){BOOL fSyncChecked;//同步机制复选检测unsigned int nNumber;//存储字符串中整数if (m_pOwner == NULL)return -1;//将同步对象同锁对象联系起来CSingleL

计数线程::Run() 函数的重载代码为：

int CCounterThread::Run()
{
BOOL fSyncChecked;//同步机制复选检测
unsigned int nNumber;//存储字符串中整数
if (m_pOwner == NULL)
return -1;
//将同步对象同锁对象联系起来
CSingleLock sLock(&(m_pOwner- >m_mutex));
while (!m_bDone)//控制线程运行，为终止线程服务
{
//取同步机制复选状态
fSyncChecked = m_pOwner- >
IsDlgButtonChecked(IDC_SYNCHRONIZE);
//确定是否使用同步机制
if (fSyncChecked)
sLock.Lock();
//读取整数
_stscanf((LPCTSTR) m_pOwner- >m_strNumber,
_T("%d"), &nNumber);
nNumber++;//加1
m_pOwner- >m_strNumber.Empty();//字符串置空
while (nNumber != 0) //更新字符串
{
m_pOwner- >m_strNumber +=
(TCHAR) ('0'+nNumber%10);
nNumber /= 10;
}
//调整字符串顺序
m_pOwner- >m_strNumber.MakeReverse();
//如果复选同步机制，释放资源
if (fSyncChecked)
sLock.Unlock();
//确定复选显示计数线程
if (m_pOwner- >IsDlgButtonChecked(IDC_SHOWCNTRTHRD))
m_pOwner- >AddToListBox(_T("Counter: Add 1"));
}//结束while
m_pOwner- >PostMessage(WM_CLOSE, 0, 0L);
return 0;
}

显示线程的::Run()函数重载代码为：

int CDisplayThread::Run()
{
BOOL fSyncChecked;
CString strBuffer;
ASSERT(m_pOwner != NULL);
if (m_pOwner == NULL)
return -1;
CSingleLock sLock(&(m_pOwner- >m_mutex));
while (!m_bDone)
{
fSyncChecked = m_pOwner- >
IsDlgButtonChecked(IDC_SYNCHRONIZE);
if (fSyncChecked)
sLock.Lock();
//构建要显示的字符串
strBuffer = _T("Display: ");
strBuffer += m_pOwner- >m_strNumber;
if (fSyncChecked)
sLock.Unlock();
//将字符串加入到列表框中
m_pOwner- >AddToListBox(strBuffer);
}//结束while
m_pOwner- >PostMessage(WM_CLOSE, 0, 0L);
return 0;
}
