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

DWORD

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();

}
