Macro to initialize GDI+ in VC6.0 MFC projects

Introduction

I have started to use GDI+ with MFC in VC++ 6.0 and got tired of always having to remember to add the GDI+ startup code and header and library files to my project. So I decided to write a simple VS macro that would do all this for me.

What's added?

In stdafx.h file the following lines are added:

// GdiPlus -- Added by the GdiPlus macro

#include <gdiplus.h>

using namespace Gdiplus;
#pragma comment (lib, "Gdiplus.lib")

In the <AppName>.h header file the following lines are added:

// GdiPlus -- Added by the GdiPlus macro

protected:
    ULONG_PTR m_gdiplustoken;

And if the application's ExitInstance() function is not already declared, a declaration is also added in the virtual functions section.

// GdiPlus -- Added by the GdiPlus macro

public:
virtual int ExitInstance();

In the <AppName>.cpp source file, the following lines are added to the InitInstance() function.

// GdiPlus -- Added by the GdiPlus macro

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

And, in the ExitInstance() function, which is added if it is not already present, the following lines are added:

// GdiPlus -- Added by the GdiPlus macro

GdiplusShutdown(m_gdiplusToken);

How to install

Simply save the GdiPlus.dsm file in your <Visual Studio>/Common/MSDev98/Macros/ folder. Then, in Dev Studio, select the Tools menu, Macro dialog. On the Macro dialog click the Options button to show an extra four buttons. Click the Loaded Files button to bring up another dialog. Scroll down the list of macro files until you find GdiPlus. Select the check box for GdiPlus and Bob's your uncle.

That's it! I hope someone finds this useful because I sure do!
