Bitmap object

[szcygan]

I have wrote this code below, it is supposed to create the bitmap object from the file. It's building ok, but when running the object has no data about the picture. Even worse - the pixel color pixelKolor doesn't change after GetPixel method... why??

#include <GdiPlus.h>
using namespace Gdiplus;

wfile = L&quot;D:\\are0.bmp&quot;;
Bitmap bitmapa(wfile, useIcm);
Color pixelKolor(100,100,100,100);
int h = bitmapa.GetHeight();
int w = bitmapa.GetWidth();
bitmapa.GetPixel(100,120,&pixelKolor);
alfa = pixelKolor.GetAlpha();

thnx

Ok... I've got it. The following was missing... whatever that is:

GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
