giving error as error C3861: '_beginthreadex': identifier not found
beginthreadex working fine without MFC code.

#include <process.h>

Usually AfxBeginThread() is used in MFC. Are you sure you need _beginthreadex()? All your parameters seem like defaults.
You might want to check the order of your #includes and the contents of stdafx.h and/or check your include directories. You also need to include <process.h> after stdafx.h. That might fix it.
