C++ AfxBeginThread

计算从1+2+3...+100000=?

关键点

CWinThread*
AfxBeginThread(

AFX_THREADPROC
pfnThreadProc,

LPVOID
pParam,

int
nPriority
=
THREAD_PRIORITY_NORMAL,

UINT
nStackSize
=
0,

DWORD
dwCreateFlags
=
0,

LPSECURITY_ATTRIBUTES
lpSecurityAttrs
=
NULL

);

UINT MyFunction( LPVOID pParam );

实现过程

class CMfc01Dlg : public CDialog

{

    // Construction

public:

    CMfc01Dlg(CWnd* pParent = NULL);    // standard constructor

    CWinThread *m_sumProc;

    // Dialog Data

    

    UINT SumPro(LPVOID pParam)

    {

        CMfc01Dlg *pDlg=(CMfc01Dlg*)pParam;

        __int64 nSum=0;

        char pszText[128]={0};

        for (UINT i=1;i<100000;i++)

        {

            nSum+=i;

            memset(pszText,0,128);

            wsprintf(pszText,"累计到%d的结果为%I64d",i,nSum);

            pDlg->m_listbox1.AddString(pszText);

        }

        return 0;

    } 

    

    void CMfc01Dlg::OnButton1() 

    {

        // TODO: Add your control notification handler code here

        m_sumProc=AfxBeginThread(SumPro,this,0,0,0,NULL);

}

void CMfc01Dlg::OnClose() 

{

    // TODO: Add your message handler code here and/or call default

    

    if (SumPro!=NULL)

    {

        DWORD dwExit=0;

        BOOL bRet=GetExitCodeThread(m_sumProc->m_hThread,&dwExit);

        if (dwExit==STILL_ACTIVE)

        {

            m_sumProc->ExitInstance();

            delete m_sumProc;

        }

    }

    

    CDialog::OnClose();

}
