Borland C++ sub windows

[Challenge]

Mi-am cumparat si eu o carte de programare sub windows pentru C++ ... cartea mi se pare destul de buna, dar am o problema.Nu stiu ce compilator folosesc ei (cei care au scris cartea) pentru ca mie in Borland C++ 4.5 nu imi gaseste windows.h (header necesar) iar in Borland C++ 5.02 imi da exact eroarea asta: "Unresolved external '_main' referenced from ...\C++\BC5\LIB\COX32.obj"

Codul este acesta (care din cate am inteles trebuia sa imi faca o fereastra de windows simpla, fara butoane sau alte controale) :

Cod:

#include

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
void FillAndRegisterClass(LPSTR, HINSTANCE);
HWND CreateApplication(LPSTR, HINSTANCE, int);

void FillAndRegisterClass(LPSTR szClassName, HINSTANCE hInstance)
{
WNDCLASSEX wndclass;

wndclass.cbSize = sizeof(wndclass);
wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH)
GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szClassName;
wndclass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);

RegisterClassEx(&wndclass);
}

HWND CreateApplication(LPSTR szClassName, HINSTANCE hInstance, int nCmdLine)
{
HWND hwnd;
hwnd = CreateWindow (
szClassName,
"Fereastra",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL) ;

ShowWindow (hwnd, nCmdLine);
UpdateWindow(hwnd);
return hwnd;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR szCmdLine, int nCmdShow)
{
static char szClassName[] = "Fereastra";
MSG msg;

FillAndRegisterClass(szClassName, hInstance);
CreateApplication(szClassName, hInstance, nCmdShow);
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
switch (iMsg)
{
case WM_CREATE :
return 0;

case WM_PAINT :
return 0;

case WM_CLOSE :
DestroyWindow(hwnd);
return 0;

case WM_DESTROY :
PostQuitMessage (0);
return 0;
}
}

(am postat si codul ca sa fiu sigur ca nu este de la el)

Ma poate ajuta cineva?

Incearca Dev-C++ (http://www.bloodshed.net/devcpp.html). Cand deschizi proiectul, selecteaza ca limbaj C (sau c++, nu cred ca o sa conteze) si Windows Application.
M-am uitat peste codul acela si nu imi creeaza fereastra (imi apare numele executabilului in Processes). Asa ca adauga urmatoarea chestie. In loc de:

Cod:

LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
    switch (iMsg)
    {
        case WM_CREATE :
            return 0;

        case WM_PAINT :
            return 0;

        case WM_CLOSE :
            DestroyWindow(hwnd);
            return 0;

        case WM_DESTROY :
            PostQuitMessage (0);
            return 0;
    }
}

Pune:

Cod:

LRESULT CALLBACK WndProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
    switch (iMsg)
    {
        case WM_CREATE :
            return 0;

        case WM_PAINT :
            return 0;

        case WM_CLOSE :
            DestroyWindow(hwnd);
            return 0;

        case WM_DESTROY :
            PostQuitMessage (0);
            return 0;
        default: return DefWindowProc (hwnd,iMsg,wParam,lParam);
    }
    return 0;
}

Bafta !

Si as mai avea o intrebare... Dev-cpp e acealsi lucru cu MinGW? Sau Dev-cpp e un IDE pentru MinGW?

[AnaKonD]

Dev-CPP este un IDE care are integrat (daca optezi pentru asta) compilatorul MinGW. Dar am vazut ca se poate utiliza si alt compilator daca vrei.

Bafta!

Bun am luat Dev-CPP si am testat codul, tot aia (ma rog, de data asta alta eroare): "[Linker error] undefined reference to 'GetStockObject@4'"    

Stie cineva ce sa ii mai fac?  :/

Uita-te la optiunile de link-editare si vezi daca apare Gdi32.lib. Daca nu, adaug-o

@Challenge: Ai selectat windows application ?
File -> New -> Project si selectezi C Project si Windows Application !

Mersi vladiii , ramand dator !
