AfxBeginThread函數創建進程

 

 

MFC使用AfxBeginThread()函數創建線程
CWinThread *AfxBeginThread(AFX_THREADPROC pfnThreadProc,LPVOID pParam,int       nPriority=THREAD_PRIORITY_NORMAL,UINT nStackSize=0,DWORD             dwCreateFlags=0,LPSECURITY_ATTRIBUTES lpSecurityAttrs=NULL)
CWinThread *AfxBeginThread(CRuntimeClass *pThreadClass,int                nPriority=THREAD_PRIORITY_NORMAL,UINT nStackSize=0,
               dwCreateFlags=0,LPSECURITY_ATTRIBUTES lpSecurityAttrs=NULL)
pfnThreadProc：表示線程函數指針，函數原型是
      UINT ControllingFunction(LPVOID pParameter);
pParam:線程函數的參數
nPriority線程的優先級
nStackSize堆棧大小
dwCreateFlags線程創建標記
lpSecurityAttrs安全屬性
pThreadClass派生於CWinThread類的運行時類對象

示例：

 

UINT Multilp(LPVOID  pThreadParam)
{
 CMutilThread1Dlg *pdlg=(CMutilThread1Dlg *)pThreadParam;
  CString s2;
   s2="";
  for(int i=1;i<=9;i++)
  {
  
   for(int j=1;j<=9;j++)
   {
    s2="";
    s2.Format("%d*%d=%d",i,j,i*j);
    pdlg->m_table.AddString(s2);
   }
  }
  return 0;
}
UINT Tital(LPVOID pThreadParam)
{
 CMutilThread1Dlg *pdlg=(CMutilThread1Dlg *)pThreadParam;
 CString s;
 s="";
 _int64 count=0;
 for(UINT i=1;i<=1000;i++)
 {
  s.Empty();
  count+=i;
  s.Format("累計到%d結果是%d",i,count);
  pdlg->m_total.AddString(s);
 }
 return 0;
}

void CMutilThread1Dlg::OnStart()
{
  m_ptable=AfxBeginThread(Multilp,this,0,0,0,NULL);
  m_ptotal=AfxBeginThread(Tital,this,0,0,0,NULL);
}

void CMutilThread1Dlg::OnCancle()
{
 DWORD exit=0;
 if(m_ptable!=NULL)//判斷是否爲空
 {
  BOOL ret=GetExitCodeThread(m_ptable->m_hThread,&exit);//獲取線程退出代碼
  if(exit==STILL_ACTIVE) //如果進程仍在進行
  {
   m_ptable->ExitInstance();//退出進程
   delete m_ptable;
  }
 }
  exit=0;
 if(m_ptotal!=NULL)//判斷是否爲空
 {
  exit=0;
  BOOL ret=GetExitCodeThread(m_ptotal->m_hThread,&exit);//獲取線程退出代碼
  if(exit==STILL_ACTIVE) //如果進程仍在進行
  {
   m_ptotal->ExitInstance();//退出進程
   delete m_ptotal;
  }
 }
 CDialog::OnCancel();
 
}
