GDIPlus use preparations

GDIPlus use

stdafx.h add the following code:

#include <comdef.h> // initialize it com port 
#include " GdiPlus.h " 
a using  namespace Gdiplus;
 #pragma the Comment (lib, "gdiplus.lib")

Starts to initialize:
(.h) added in a statement app's category:

ULONG_PTR m_gdiplusToken;

InitInstance () where, in DoModal () function earlier, adding: // If there is no usingnamespace Gdiplus; we should add Gdiplus in front ::

GdiplusStartupInput gdiplusStartupInput;
GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);

Overload ExitInstance, added GdiplusShutdown (m_gdiplusToken);

int CxxxApp :: the ExitInstance () 
{ 
    // the TODO: add this special code and / or calls the base class 
    GdiplusShutdown (m_gdiplusToken);
     return the CWinApp :: the ExitInstance (); 
}
