[Dev-C++] Simplequestions

[Yohaan <jsh...@ho...>]

I asked a question a bit ago through the list, however my terminology is no=
t correct. so in order to be able to pursue the learning process and focus =
thoughts, a rephrasing of the questions appears to be in order. Following i=
s the simpwin code from dev 4.9.9.2 :        /* Creation of a simple Window=
s API program */#include <windows.h>/*  Declare Windows procedure  */LRESUL=
T CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);/*  Make the class =
name into a global variable  */char szClassName[ ] =3D "WindowsApp";int WIN=
APIWinMain (HINSTANCE hThisInstance,         HINSTANCE hPrevInstance,      =
   LPSTR lpszArgument,         int nFunsterStil){    HWND hwnd;            =
   /* This is the handle for our window */    MSG messages;            /* H=
ere messages to the application are saved */    WNDCLASSEX wincl;        /*=
 Data structure for the windowclass */    /* The Window structure */    win=
cl.hInstance =3D hThisInstance;    wincl.lpszClassName =3D szClassName;    =
wincl.lpfnWndProc =3D WindowProcedure;      /* This function is called by w=
indows */    wincl.style =3D CS_DBLCLKS;                 /* Catch double-cl=
icks */    wincl.cbSize =3D sizeof (WNDCLASSEX);    /* Use default icon and=
 mouse-pointer */    wincl.hIcon =3D LoadIcon (NULL, IDI_APPLICATION);    w=
incl.hIconSm =3D LoadIcon (NULL, IDI_APPLICATION);    wincl.hCursor =3D Loa=
dCursor (NULL, IDC_ARROW);    wincl.lpszMenuName =3D NULL;                 =
/* No menu */    wincl.cbClsExtra =3D 0;                      /* No extra b=
ytes after the window class */    wincl.cbWndExtra =3D 0;                  =
    /* structure or the window instance */    /* Use Windows's default colo=
r as the background of the window */    wincl.hbrBackground =3D (HBRUSH) CO=
LOR_BACKGROUND;    /* Register the window class, and if it fails quit the p=
rogram */    if (!RegisterClassEx (&wincl))        return 0;    /* The clas=
s is registered, let's create the program*/    hwnd =3D CreateWindowEx (   =
        0,                   /* Extended possibilites for variation */     =
      szClassName,         /* Classname */           "Window App",       /*=
 Title Text */           WS_OVERLAPPEDWINDOW, /* default window */         =
  CW_USEDEFAULT,       /* Windows decides the position */           CW_USED=
EFAULT,       /* where the window ends up on the screen */           544,  =
               /* The programs width */           375,                 /* a=
nd height in pixels */           HWND_DESKTOP,        /* The window is a ch=
ild-window to desktop */           NULL,                /* No menu */      =
     hThisInstance,       /* Program Instance handler */           NULL    =
             /* No Window Creation data */           );    /* Make the wind=
ow visible on the screen */    ShowWindow (hwnd, nFunsterStil);    /* Run t=
he message loop. It will run until GetMessage() returns 0 */    while (GetM=
essage (&messages, NULL, 0, 0))    {        /* Translate virtual-key messag=
es into character messages */        TranslateMessage(&messages);        /*=
 Send message to WindowProcedure */        DispatchMessage(&messages);    }=
    /* The program return-value is 0 - The value that PostQuitMessage() gav=
e */    return messages.wParam;}/*  This function is called by the Windows =
function DispatchMessage()  */LRESULT CALLBACKWindowProcedure (HWND hwnd, U=
INT message, WPARAM wParam, LPARAM lParam){    switch (message)            =
      /* handle the messages */    {             case WM_DESTROY:          =
  PostQuitMessage (0);       /* send a WM_QUIT to the message queue */     =
       break;        default:                      /* for messages that we =
don't deal with */            return DefWindowProc (hwnd, message, wParam, =
lParam);    }    return 0;}1. a) Why when this code is a source file, does =
the window opened contain both the 'command console' style of window and th=
e window described by the code? b)What part of the linking and compiling pr=
ocess is the default window? c)2. In the array  hwnd =3D CreateWindowEx the=
 twelfth element appears to be the 'window creation data' does this allow m=
e to call a .rc from this element? 3. Is the message  switch function where=
 the messages are handled?These are obviously very basic questions, yet by =
the very asking I have seen a new manner of approach which could be fun. so=
 thanks and take care....
