Q: How to create a worker thread?
A: There are several ways to create a worker thread:

• '_beginthread()' (C run-time library)
• '_beginthreadex()' (C run-time library)
• 'CreateThread()' (Win32 API)
• 'CreateRemoteThread()' (Win32 API)
• 'AfxBeginThread()' (MFC)

The following samples will show the creation of a thread using the three functions '_beginthreadex()', 'CreateThread()' and 'AfxBeginThread()'.

1. '_beginthreadex()'
   
   class CFoo
   {
   public:
   CFoo()
   {
   m_uiThreadID = 0;
   m_ulThreadHandle = 0;
   }
   bool Create()
   {
   m_ulThreadHandle = _beginthreadex(0,
   0,
   ThreadFunc,
   this,
   0,
   &m_uiThreadID);
   if(!m_ulThreadHandle)
   {
   // Could not create thread
   return false;
   }
   return true;
   }
   private:
   unsigned int m_uiThreadID;
   unsigned long m_ulThreadHandle;
   static unsigned int __stdcall ThreadFunc(void *pvParam);
   };
2. 'AfxBeginThread()'
   
   class CMyDialog : public CDialog
   {
   public:
   CMyDialog(CWnd* pParent = NULL)
   : CDialog(CMyDialog::IDD, pParent)
   {
   m_pThread = 0;
   }
   bool Create()
   {
   m_pThread = AfxBeginThread(ThreadFunc, this);
   if(!m_pThread)
   {
   // Could not create thread
   return false;
   }
   return true;
   }
   private:
   CWinThread *m_pThread;
   static UINT ThreadFunc(LPVOID pvParam);
   };
