Aliens prevent this code from working (resource files)?

[kikelinus]

I tried to make a simple window that has menus and an icon using resource files. I compiles ok, and says that there are no errors, but the window class cannot be registered. I think I did something wrong while linking the menu and icon in the resource file to the program itself.

Can someone please tell me where my mistake is?
Thanks.
(I am using Visual c++ 6.)

Change you main.cpp file's content to this:

#include <windows.h>
#include "resource.h"

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                   PSTR szCmdLine, int iCmdShow)
{
    static TCHAR szAppName[]= TEXT("HelloWin");
    HWND        hwnd;
    MSG            msg;
    WNDCLASS    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 =  MAKEINTRESOURCE(IDR_MENU);

    wndclass.lpszClassName = szAppName;

    if (!RegisterClass (&wndclass))
    {
        MessageBox(NULL, TEXT("This program requires Windows NT!"), 
                    szAppName, MB_ICONERROR);
        return 0;
    }

hwnd = CreateWindow(szAppName,                        // window class name
                    TEXT("The Hello Program"),        // window caption
                    WS_OVERLAPPEDWINDOW,            // window style
                    CW_USEDEFAULT,                    // initial x position
                    CW_USEDEFAULT,                    // initial y position

                    NULL,                            // window menu handle
                    hInstance,                        // program instance handle
                    NULL);                            // creation parameters

ShowWindow(hwnd, iCmdShow) ;
UpdateWindow(hwnd);

while (GetMessage (&msg, NULL,0,0))
{
    TranslateMessage(&msg);
    DispatchMessage(&msg);

    return msg.wParam;

    case WM_PAINT:
        hdc = BeginPaint(hwnd, &ps);

                
        EndPaint(hwnd,&ps);
        return 0;

    case WM_DESTROY:
