中
m_pOwner- >AddToListBox(strBuffer);
}//结束while
m_pOwner- >PostMessage(WM_CLOSE, 0, 0L);
return 0;
}

3在CMutexesDlg的头文件中加入如下成员变量：
CString m_strNumber;//线程所要操作的资源对象
CMutex m_mutex;//用于同步机制的互斥量
CCounterThread* m_pCounterThread;//指向计数线程的指针
CDisplayThread* m_pDisplayThread;//指向显示线程的指针
首先在对话框的初始化函数中加入如下代码对对话框进行初始化：
BOOL CMutexesDlg::OnInitDialog()
{
……
//初始化进程优先级组合框并置缺省为NORMAL
CComboBox* pBox;
pBox = (CComboBox*) GetDlgItem(IDC_PRIORITYCLASS);
ASSERT(pBox != NULL);
if (pBox != NULL){
pBox- >AddString(_T("Idle"));
pBox- >AddString(_T("Normal"));
pBox- >AddString(_T("High"));
pBox- >AddString(_T("Realtime"));
pBox- >SetCurSel(1);
}
//初始化显示线程优先级组合框并置缺省为NORMAL
pBox = (CComboBox*) GetDlgItem(IDC_DSPYTHRDPRIORITY);
ASSERT(pBox != NULL);
if (pBox != NULL){
pBox- >AddString(_T("Idle"));
pBox- >AddString(_T("Lowest"));
pBox- >AddString(_T("Below normal"));
pBox- >AddString(_T("Normal"));
pBox- >AddString(_T("Above normal"));
pBox- >AddString(_T("Highest"));
pBox- >AddString(_T("Timecritical"));
pBox- >SetCurSel(3);
}
//初始化计数线程优先级组合框并置缺省为NORMAL
pBox = (CComboBox*) GetDlgItem(IDC_CNTRTHRDPRIORITY);
ASSERT(pBox != NULL);
if (pBox != NULL){
pBox- >AddString(_T("Idle"));
pBox- >AddString(_T("Lowest"));
pBox- >AddString(_T("Below normal"));
pBox- >AddString(_T("Normal"));
pBox- >AddString(_T("Above normal"));
pBox- >AddString(_T("Highest"));
pBox- >AddString(_T("Timecritical"));
pBox- >SetCurSel(3);
}
//初始化线程挂起复选框为挂起状态
CButton* pCheck = (CButton*) GetDlgItem(IDC_PAUSE);
pCheck- >SetCheck(1);
//初始化线程
m_pDisplayThread = (CDisplayThread*)
AfxBeginThread(RUNTIME_CLASS(CDisplayThread),
THREAD_PRIORITY_NORMAL,
0,
CREATE_SUSPENDED);
m_pDisplayThread- >SetOwner(this);

m_pCounterThread = (CCounterThread*)
AfxBeginThread(RUNTIME_CLASS(CCounterThread),
THREAD_PRIORITY_NORMAL,
0,
CREATE_SUSPENDED);
m_pCounterThread- >SetOwner(this);
……
}
然后填加成员函数：
void AddToListBox(LPCTSTR szBuffer);//用于填加列表框显示
该函数的实现代码为：
void CMutexesDlg::AddToListBox(LPCTSTR szBuffer)
{
CListBox* pBox = (CListBox*) GetDlgItem(IDC_DATABOX);
ASSERT(pBox != NULL);
if (pBox != NULL){
int x = pBox- >AddString(szBuffer);
pBox- >SetCurSel(x);
if (pBox- >GetCount() > 100)
pBox- >DeleteString(0);
}
}
---- 然后利用ClassWizard 填加用于调整进程优先级、两个线程优先级以及用于复选线程挂起的函数。
---- 调整进程优先级的代码为：

void CMutexesDlg::OnSelchangePriorityclass()
{
DWORD dw;
//取焦点选项
CComboBox* pBox = (CComboBox*)
GetDlgItem(IDC_PRIORITYCLASS);
int nCurSel = pBox- >GetCurSel();
switch (nCurSel)
{
case 0:
dw = IDLE_PRIORITY_CLASS;break;
case 1:
default:
dw
