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 {

 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
