进度条的优先级比对

一共设置了三个优先级，第一个正常优先级，第二个低优先级，第三个高优先级

运行效果：

代码：

 1 void CTestProgressDlg::OnBnClickedBtnStart()

 2 {

 3     // TODO: 在此添加控件通知处理程序代码

 4     // 创建线程

 5     m_hThread1 = CreateThread(NULL, 0, Thread1, this, CREATE_SUSPENDED, NULL);

 6     m_hThread2 = CreateThread(NULL, 0, Thread2, this, CREATE_SUSPENDED, NULL);

 7     m_hThread3 = CreateThread(NULL, 0, Thread3, this, CREATE_SUSPENDED, NULL);

 8     // 设置线程优先级

 9     SetThreadPriority(m_hThread1, THREAD_PRIORITY_NORMAL);

10     SetThreadPriority(m_hThread2, THREAD_PRIORITY_LOWEST);

11     SetThreadPriority(m_hThread3, THREAD_PRIORITY_HIGHEST);

12     // 唤醒线程

13     ResumeThread(m_hThread1);

14     ResumeThread(m_hThread2);

15     ResumeThread(m_hThread3);
