GDI+ and Fat API

[mmscg]

I am trying to figure out how to call a GDI+ Flat Api function, but cannot get anything working.

Here is my code:

#include <windows.h>
#include <objidl.h>
#include <gdiplus.h>
#include <GdiplusFlat.h>
using namespace Gdiplus;
#pragma comment (lib,"Gdiplus.lib")

VOID OnPaint(HDC hdc)
{
	Graphics graphics(hdc);
	Pen      pen(Color(255, 0, 0, 255));
	//graphics.DrawLine(&pen, 0, 0, 200, 100);
	GdipDrawLine(&graphics, &pen, 0, 0, 200, 0); //Flat Api version
}

Here I am trying to call only one flat function GdipDrawLine.

Any suggestions?
