this can't be NULL when the non-static member function is called, can it?

Object *ptr = NULL;

void Object_Function(Object *this,int arg1,int arg2)

The CWinApp class derives from CWinThread, so for an MFC GUI app,
your required CWinApp object generally provides the first/main

Here we create a "control". That control has a message loop in its source code which was written by controls developer.

If view window has a message loop, is that mean it is created by a new thread?
