Creating CMFCDesktopAlertWnd Control in Visual C++ - c++

Question

MSDN contains an example for creating a desktop alert window:
http://msdn.microsoft.com/en-us/library/bb983515.aspx
The sample code starts with the following declaration.
CMFCDesktopAlertWnd* pPopup = new CMFCDesktopAlertWnd;
When I use it in my code, the compiler complains
'CMFCDesktopAlertWnd' : no appropriate default constructor available
This is the complete source code of my application.
(I created an empty Win32 project in Visual Studio and set
the Use MFC in a Shared DLL option on the Property | General page.)
#include <afxwin.h>
#include <afxDesktopAlertDialog.h>
class Notifier : public CWinApp
{
public:
virtual BOOL InitInstance();
};
BOOL Notifier::InitInstance()
{
CMFCDesktopAlertWnd* pPopup = new CMFCDesktopAlertWnd;
return TRUE;
}
Notifier myApp;
What am I doing wrong?
The effect is the same in VS Express 2008 and the full version of VS 2010.

Answer 1

Are you using VS 2008 SP1? (The service pack is important)
Are you including the proper headers in stdafx.h? More specifically, you need
#include < afxext.h >
#include < afxcontrolbars.h >
to be able to use MFC Next (feature pack) classes.
It won't work on VS Express anyway because that doesn't include MFC.
