Is ATL / WTL required to use the _Module global variable?

Question

I am just starting a new ATL / WTL project and I was wondering if the _Module global variable is needed?

A few years ago, when I started working with WTL, it was required (at least for ATL 3.0) to define a global variable, for example:

CAppModule _Module;

For ATL to work correctly. But lately I read somewhere that this might not be needed anymore (yet the code created by the wizard still uses it). In addition, I searched through Visual C ++ include directories, and it only raised _Module in several places - primarily in the ATL COM registry entry.

So what else do I need to define a global variable for using ATL these days?

Answer 1

_Module, ATL/WTL 7. ATL/WTL _Module , . _AtlBaseModule, atlcore.h.

, WTL CAppModule CComModule. COM, .. , WTL - CComModule. _Module.

Answer 2

WTL .

stdafx.h:

extern CAppModule _Module;

:

CAppModule _Module;
