MFC四种方法编写多线程

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

cpp 复制代码

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);
}

cpp 复制代码

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

cpp 复制代码

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

cpp 复制代码

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

cpp 复制代码

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);
}
