MFC四种方法编写多线程

news 2025/7/2 14:08:15

本文以四个demo为例，对MFC的多线程进行学习。学习的过程中写了四个demo，将其做成笔记，发布在csdn上面。

mfc多线程demo1

volatile BOOL m_bRun;
CEdit* edit;
void ThreadFunc(){CTime time;CString strTime;m_bRun = true;while(m_bRun){time = CTime::GetCurrentTime();strTime = time.Format("%H:%M:%S");//::SetDlgItemText(AfxGetMainWnd()->m_hWnd,IDC_EDIT1,strTime);edit->SetWindowText(strTime);Sleep(1000);}}void CmfcMultiThread02Dlg::OnBnClickedButton1()
{// 作死卡死edit = &m_list;hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)ThreadFunc,NULL,0,&ThreadID);btn1.EnableWindow(FALSE);btn2.EnableWindow(TRUE);
}void CmfcMultiThread02Dlg::OnBnClickedButton2()
{// TODO: 在此添加控件通知处理程序代码m_bRun = FALSE;btn1.EnableWindow(TRUE);btn2.EnableWindow(FALSE);
}

mfc多线程demo2

volatile BOOL m_bRun;
CEdit* edit;
void ThreadFunc(int n){int i ;for( i = 0;i< n;i++){Sleep(1000);}}void CmfcMultiThread02Dlg::OnBnClickedButton1()
{// 作死卡死UpdateData(TRUE);  int n=2;  hThread=CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)ThreadFunc, (VOID*)n, 0, &ThreadID);  btn1.EnableWindow(FALSE);  WaitForSingleObject(hThread,INFINITE);  btn2.EnableWindow(TRUE);  }void CmfcMultiThread02Dlg::OnBnClickedButton2()
{// TODO: 在此添加控件通知处理程序代码m_bRun = FALSE;btn1.EnableWindow(TRUE);btn2.EnableWindow(FALSE);
}

mfc多线程demo3

struct threadInfo{UINT	 nMilliSecond;CProgressCtrl* pctrlProgress;
};
threadInfo info;
UINT ThreadFunc(LPVOID lpParam){threadInfo* pInfo = (threadInfo*)lpParam;for(int i = 0;i < 100;i++){int nTemp = pInfo->nMilliSecond;pInfo->pctrlProgress->SetPos(i);Sleep(nTemp);}return 0;}
void CmfcMultiThread02Dlg::OnBnClickedButton1()
{// 作死卡死UpdateData(TRUE);  info.nMilliSecond = 50;info.pctrlProgress = &progress1;hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)ThreadFunc, &info, 0, &ThreadID);}

mfc创建线程数统计demo4

volatile BOOL m_bRunFlag = TRUE;
DWORD WINAPI threadFunc(LPVOID threadNum){while(m_bRunFlag){Sleep(3000);}return 0;}
void CmfcMultiThread02Dlg::OnBnClickedButton1()
{// 作死卡死DWORD threadID;btn1.EnableWindow(FALSE);long nCount = 0;while(m_bRunFlag){if(CreateThread(NULL,0,threadFunc,NULL,0,&threadID) == NULL){m_bRunFlag = false;break;}else{nCount++;}}UpdateData(FALSE);Sleep(5000);btn1.EnableWindow(TRUE);CString tempPort;tempPort.Format(_T("%d"), nCount );m_list.SetWindowText(tempPort);m_bRunFlag = TRUE;
}

mfc创建线程进度条

struct threadInfo{UINT nMillSecond;CProgressCtrl* pctrlProgress;}info;UINT ThreadFunc(LPVOID lpParam){threadInfo* pInfo = (threadInfo*) lpParam;for(int i = 0;i< 100;i++){int nTemp = pInfo->nMillSecond;pInfo->pctrlProgress->SetPos(i);Sleep(nTemp);}return 0;}
void CmfcMultiThread02Dlg::OnBnClickedButton1()
{// 作死卡死UpdateData(TRUE);info.nMillSecond = 10;info.pctrlProgress = &progress1;pThread = AfxBeginThread(ThreadFunc,&info);
}
