DirectX9 - Problems to arrange bitmap

Korowai

Hi, i properly have coded a bitmap to be drawn in a control child of a dialogue in WINAPI. Now i want to fit the bitmap, that has to be bigger than the window size, in specific coordinates, lateron i want to make controls that move the picture in the window. My problem is i really don't know where i can set the variables who arrange the picture. Here's the code (only the main, the headers are not neccessary):

#if defined(UNICODE) && !defined(_UNICODE)
#define _UNICODE
#elif defined(_UNICODE) && !defined(UNICODE)
#define UNICODE
#endif

#include

#include "Resource.h"
