Minimalist Windows programming

#include <stdio.h> int main ()
{PRINTFSS ("Hello world\n");   return 0; }

Countless people know this code, but the number of the following code is slightly less than the above.

#include <windows.h>

int main ()

{

MessageBox (NULL, "Hello World", "window", MB_OK);

return 0;

}

After these two pieces of code will display a DOS window, the following code brings you into the Windows environment, there is no DOS window what happened.

#include <windows.h>

int WINAPI WinMain (hinstance hins,hinstance prehins,lpstr Show)

{

MessageBox (NULL, "Hello World", "window", MB_OK);

return 0;
}

In this way, you write one of the simplest Windows programs, but there is only one message box, there is no real sense of the window.

#include <windows.h>

Message handler function
Lresult CALLBACK winporc (HWND hwnd,uint msg,wparam wparam,lparam);

int WINAPI WinMain (hinstance hins,hinstance phins,lpstr Show)
{
HWND hwnd;
MSG msg;
Wndclass Wnd;

ZeroMemory (&wnd,sizeof (WNDCLASS));
Wnd.hbrbackground = (hbrush):: Getstockobject (Dkgray_brush);
Wnd.hinstance = Hins;
Wnd.lpfnwndproc = WINPORC;
Wnd.lpszclassname= "Test";
Wnd.style = Cs_vredraw|cs_hredraw;

if (!::registerclass (&wnd))
{
return 0;
}

hwnd =:: CreateWindow ("Test", "Test", ws_overlapped| Ws_sysmenu,0,0,100,100,null,null,hins,null);
 if (hwnd==null)
 {
  return 0;
 }
 
 showwindow (hwnd,show );
 updatewindow (HWND);
 
 while (TRUE) {
  if (::P eekmessage (&msg,null,0,0,pm_remove)) {
    if (Msg.message = = wm_quit) {
    break;
   }  
  ::translatemessage (&MSG);
  ::D ispatchmessage (&msg);
  }
 }
    return 0;
}

Lresult CALLBACK winporc (HWND hwnd,uint msg,wparam Wparam,lparam)
{
Switch (msg) {
Case Wm_destroy:
PostQuitMessage (0);
Break
Default
Break
}
return::D Efwindowproc (Hwnd,msg,wparam,lparam);
}
