I doubt there're any problems using extern for that but you could also use AfxGetApp(), i think that is the preferred method.

You may declare it wherever you need, for instance suppose you application class name is CMyApp then you probably have, in your MyApp.cpp source file some lines like the following

/////////////////////////////////////////////////////////////////////////////
// The one and only CMyApp object
CMyApp theApp;

if you need it inside, say, MyView.cpp, then you write, somewhere at the top of the file

// this is MyView.cpp source file
//
#include "MyApp.h"
extern CMyApp theApp;

If you need to reach it globally in your project then just declare it (i.e. write extern CMyApp theApp;) inside your main header file, MyApp.h (that in turn is usually included by all of the source files). :)
