Question

我需要一些资源文件的帮助。我不理解我在这些文件中犯的错误。

  

resource.h第5行错误：数字常量之前的unqualified-id，resources.rc第6行注意：in   扩展宏观＆＃39; IDI_MYICON＆＃39;

main.cpp中：

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

const char g_szClassName[] = "myWindowsClass";

//Windows procedure

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch(msg)
    {
    case WM_CREATE:
        {
            HMENU hMenu, hSubMenu;
            HICON hIcon, hIconSm;

            hMenu = CreateMenu();

            hSubMenu = CreatePopupMenu();
            AppendMenu(hSubMenu, MF_STRING, ID_FILE_EXIT,"E&xit");
            AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu,"&File");

            hSubMenu = CreatePopupMenu();
            AppendMenu(hSubMenu, MF_STRING, ID_STUFF_GO, "&Go");

            SetMenu(hwnd, hMenu);

            hIcon = (HICON)LoadImage(NULL, "menu_two.ico", IMAGE_ICON, 32, 32, LR_LOADFROMFILE);
            if(hIcon)
                SendMessage(hwnd, WM_SETICON, ICON_BIG, (LPARAM)hIcon);
            else
                MessageBox(hwnd, "Could not load large icon!", "Error", MB_OK | MB_ICONEXCLAMATION);
            hIconSm = (HICON)LoadImage(NULL, "menu_two.ico", IMAGE_ICON, 16, 16, LR_LOADFROMFILE);
            if(hIconSm)
                SendMessage(hwnd, WM_SETICON, ICON_SMALL, (LPARAM)hIconSm);
            else
                MessageBox(hwnd, "Could not load small icon!", "Error", MB_OK | MB_ICONEXCLAMATION);
        }
        break;
    case WM_COMMAND:
        switch(LOWORD(wParam))
        {
        case ID_FILE_EXIT:
            PostMessage(hwnd, WM_CLOSE, 0,0);
            break;
        case ID_STUFF_GO:

            break;
        }
        break;
    case WM_CLOSE:
        DestroyWindow(hwnd);
        break;
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    default:
        return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)

    }

    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    //The Message Loop
    while(GetMessage(&Msg, NULL, 0, 0) > 0)
    {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }

    return Msg.wParam;
}

resource.h中：

#include "resources.rc"

#define ID_FILE_EXIT 4001
#define ID_STUFF_GO 9002
#define IDI_MYICON 9008

resources.rc：

#ifndef _RESOURCES_RC_
#define _RESOURCES_RC_

#include "resource.h"

IDI_MYICON ICON "menu_two.ico"

IDR_MYMENU MENU
{
    POPUP "&File"
    {
        MENUITEM "E&xit", ID_FILE_EXIT
    }
}
#endif //_RESOURCES_RC_

Answer 1

resource.h文件不应该#include resources.rc文件。
