Hello there, if anyone interested I've just uploaded my updated tuto on GDI Win graphics.

There are here many new stuff from the last one though many to do yet, including translating

it to English, but I'm getting more lazy to work on it, though surely I will keep on making

things for it. In the other hand, there're many things that I've removed from the downloable

version, that may be not in the interest of anybody.

Now you can download the entire tuto from here.

Also you can download the libs from here, but you need login first in my forum. The

registering is 100% free, but you have to provide a valid email to complete it. I did it

just for have an idea of how many times it was downloaded (at least one time for my checking

Wink ) and by who... I know, I know, you are rather shy and can't do it. Never mind, many

codes really don't need libs...

Besides, there're many new things from last one.

Oops, I must say that the libs have failed while downloading, I will check it as soon as I

can Smile

In the end... Good fun

Nice package, clear code, impressive graphics.

You have TinyCC sources, too Smile Try this example I wrote for TinyCC:
Code:
#pragma optimize("t", on)
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
 
#define title "Create HBITMAP"
#define class_name "WC"

int screen_w, screen_h;
HINSTANCE instance;
HWND window;
MSG msg;

LRESULT CALLBACK wproc(HWND w, UINT m, WPARAM wp, LPARAM lp);

HBITMAP hbmp;

#define W 0xFFFFFF  // colors: white, black, yellow
#define B 0
#define Y 0xFFFF00

unsigned bmp[] = {  // example 8x8 face image
W,W,B,B,B,B,W,W,
W,B,Y,Y,Y,Y,B,W,
B,Y,B,Y,Y,B,Y,B,
B,Y,B,Y,Y,B,Y,B,
B,Y,Y,Y,Y,Y,Y,B,
B,Y,B,B,B,B,Y,B,
W,B,Y,Y,Y,Y,B,W,
W,W,B,B,B,B,W,W };

WNDCLASSEX wc={ 48, 0, wproc, 0, 0, 0, 0, 0, 0, 0,
 class_name, 0 };

int WINAPI WinMain(HINSTANCE hi, HINSTANCE na,
 PSTR c, int na2) {
 instance=hi;
 wc.hInstance=hi;
 wc.hCursor=(HCURSOR) LoadCursor(0, IDC_ARROW);
 wc.hbrBackground=(HBRUSH) GetStockObject(WHITE_BRUSH);
 screen_w=GetSystemMetrics(SM_CXSCREEN);
 screen_h=GetSystemMetrics(SM_CYSCREEN);
 if (!RegisterClassEx(&wc) ||
  !(window=CreateWindowEx(0, class_name, title,
  WS_VISIBLE+WS_POPUP, 0, 0, screen_w, screen_h,
  0, 0, hi, 0)))
 return 1;

 hbmp=CreateBitmap(8, 8, 32, 1, bmp);

 for (;Wink {
  if (!GetMessage(&msg, 0, 0, 0))
   return msg.wParam;
  TranslateMessage(&msg);
  DispatchMessage(&msg);
 }
 return msg.wParam;
}
  
LRESULT CALLBACK wproc(HWND w, UINT m,
 WPARAM wp, LPARAM lp) {
 if (m==WM_KEYDOWN && wp==VK_ESCAPE)
  goto exit;
 else if (m==WM_PAINT) {
  HDC dc=GetDC(window), mdc=CreateCompatibleDC(dc);
  SelectObject(mdc, hbmp);
  StretchBlt(dc, 0, 0, screen_w+1, screen_h+1, mdc,
   0, 0, 8, 8, SRCCOPY);
  ReleaseDC(window, dc);
  DeleteDC(mdc);
  return 1;
 }
 if (m==WM_CLOSE) {
  exit: PostQuitMessage(0);
  return 1;
 }
 return DefWindowProc(w, m, wp, lp);
}
