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); 16 } 17 DWORD WINAPI CTestProgressDlg::Thread1(LPVOID lpParam) 18 { 19 CTestProgressDlg *pDlg = (CTestProgressDlg*)lpParam; 20 for(int i = 0;i < 10000;i++) 21 { 22 pDlg->m_progress1.SetPos(i); 23 } 24 return 0; 25 } 26 DWORD WINAPI CTestProgressDlg::Thread2(LPVOID lpParam) 27 { 28 CTestProgressDlg *pDlg = (CTestProgressDlg*)lpParam; 29 for(int i = 0;i < 10000;i++) 30 { 31 pDlg->m_progress2.SetPos(i); 32 } 33 return 0; 34 } 35 DWORD WINAPI CTestProgressDlg::Thread3(LPVOID lpParam) 36 { 37 CTestProgressDlg *pDlg = (CTestProgressDlg*)lpParam; 38 for(int i = 0;i < 10000;i++) 39 { 40 pDlg->m_progress3.SetPos(i); 41 } 42 return 0; 43 } 44 45 void CTestProgressDlg::OnBnClickedBtnPause() 46 { 47 // TODO: 在此添加控件通知处理程序代码 48 SuspendThread(m_hThread1); 49 SuspendThread(m_hThread2); 50 SuspendThread(m_hThread3); 51 } 52 53 void CTestProgressDlg::OnBnClickedBtnContinue() 54 { 55 // TODO: 在此添加控件通知处理程序代码 56 ResumeThread(m_hThread1); 57 ResumeThread(m_hThread2); 58 ResumeThread(m_hThread3); 59 }
