步骤3 添加菜单响应函数 Class Name Objects IDs Messages 1. CThreadTestView ID_THREAD_START COMMAND 2. CThreadTestView ID_TREEAD_OTHER COMMAND 9.1 void CThreadTestView::OnThreadStart() { HWND hWnd = GetSafeHwnd(); AfxBeginThread(TreadProc, hWnd, THREAD_PRIORITY_NORMAL); } void CThreadTestView::OnThraedOther() { CDlgThread dlg; dlg.DoModal(); }
9.1 步骤4编写线程函数 1.在视类中添加两个成员变量。并在构造函数中初始化 class CThreadTestview: public Cview C Thread TestView: C Thread Testviey m strMessage="没有线程启动"; public: m itime =0 CString m strMessage int m iTime;
步骤4 编写线程函数 1. 在视类中添加两个成员变量。并在构造函数中初始化 9.1 class CThreadTestView : public CView { …… public: CString m_strMessage; int m_iTime; …… } CThreadTestView::CThreadTestView() { m_strMessage = "没有线程启动"; m_iTime = 0; }
9.1 步骤5在视中输出信息 void CThread Testview:: On DraW(CDC pDc) CThread TestDoc' pDoc GetDocumento ASSERT VALID(pDoc); lI TODO: add draw code for native data here char ch Number[6: itoa(m iTime, chNumber, 10); pDC->Textout(30, 30, m strMessage) pDC->Textout(30, 50, ch Number)
步骤5 在视中输出信息 9.1 void CThreadTestView::OnDraw(CDC* pDC) { CThreadTestDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); // TODO: add draw code for native data here char chNumber[6]; itoa(m_iTime, chNumber, 10); pDC->TextOut(30,30, m_strMessage); pDC->TextOut(30,50,chNumber); }
2.线程函数 9.1 UINT TreadProc(LPVOID param) CThreadTestApp"pApp=(cThreadTestApp ")AfX GetAppo CMain Frame *pAin Frame =(CMain Frame *)pApp->GetMainWnd(; CThreadTestView pView =(CThreadTestview ")pAin Frame->GetActiveViewO pview> m-strMessage="启动了一个线程!"; while(pview->m_iTime 20) . Sleep (1000) pView->m iTime ++ pView->Invalidate pView->m iTime =0; pview> m strMMessage="线程结東!"; return 0;
2. 线程函数 9.1 UINT TreadProc(LPVOID param) { CThreadTestApp *pApp=(CThreadTestApp *) AfxGetApp(); CMainFrame *pMainFrame = (CMainFrame *)pApp->GetMainWnd(); CThreadTestView *pView = (CThreadTestView *) pMainFrame->GetActiveView(); pView->m_strMessage = "启动了一个线程！"; while(pView->m_iTime < 20) { ::Sleep(1000); pView->m_iTime ++; pView->Invalidate(); } pView->m_iTime =0; pView->m_strMessage = "线程结束！"; return 0; }
