c++键盘加速器功能不起作用

Question

我一直在接受如何制作键盘加速键的培训，但是当我尝试时，它不起作用..这是代码:

资源文件::

    #include "resource.h"

    IDM_MAINMENU MENU
    BEGIN
        POPUP "&File"
        BEGIN
            POPUP "&Program"
                BEGIN

                MENUITEM "LED O&N", IDM_PROGRAM_LED_ON
                MENUITEM "LED O&FF", IDM_PROGRAM_LED_OFF
                MENUITEM "LED &BLINK", IDM_PROGRAM_LED_BLINK

                END
            MENUITEM SEPARATOR
            MENUITEM "E&xit", IDM_FILE_EXIT
        END
        POPUP "&Help"
        BEGIN
            MENUITEM "&Info", IDM_INFO
        END

    END


    app_icon   ICON "untitled.ico"

    IDA_ACCEL_TABLE ACCELERATORS
    BEGIN
       "x", IDA_CTRL_X, CONTROL, VIRTKEY
    END

头文件:

        #define  app_icon              1
        #define  IDM_MAINMENU          2
        #define  IDM_FILE_EXIT         3
        #define  IDA_ACCEL_TABLE       4
        #define  IDD_DIALOG            5
        #define  IDA_CTRL_X            6
        #define  IDM_PROGRAM_LED_OFF   7
        #define  IDM_PROGRAM_LED_BLINK 8
        #define  IDM_PROGRAM_LED_ON    9
        #define  IDM_INFO              10

主 .exe 文件::

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

        LRESULT CALLBACK WinProc(HWND hWnd,UINT message,WPARAM wParam,LPARAM lParam);

        int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShowCmd){


        window win;
        MSG msg;
        HMENU hMenu;
        hMenu = LoadMenu(hInst, MAKEINTRESOURCE(IDM_MAINMENU));
        HACCEL hAccel;
        hAccel = LoadAccelerators(hInst, MAKEINTRESOURCE(IDA_ACCEL_TABLE));

        win.cbClsExtra = NULL;                             //Additional parameters
        win.cbWndExtra = NULL;                            //Additional parameters
        win.hbrBackground = (HBRUSH)COLOR_WINDOW ;                        //Sets background color for the window
        win.hCursor = LoadCursor(NULL, IDC_ARROW);      //The cursor that will appear in the window
        win.hIcon = LoadIcon(hInst, MAKEINTRESOURCE(app_icon));                              //Icon for the window
        win.hInstance = hInst;                        //Handle to the application instance
        win.lpszClassName = "Window Class";          //The unique name of the window class
        win.lpszMenuName = NULL;                    //Used for menus
        win.style = NULL;                          //The look and feel of the window
        win.lpfnWndProc=(WNDPROC)WinProc;         //The callback procedure (more on that later)

        RegisterClass(&win);
        HWND hwnd = CreateWindow("Window Class", "Atmel Microcontroller Programmer", WS_OVERLAPPEDWINDOW, 550, 300, 350, 260, NULL, hMenu, hInst, NULL);
        ShowWindow(hwnd, SW_SHOWNORMAL);

        while(GetMessage(&msg, NULL, 0, 0)){


            if(!TranslateAccelerator(hwnd, hAccel, &msg)){
                TranslateMessage(&msg);
                DispatchMessage(&msg);
            }

        }

        return 0;

        }

        LRESULT CALLBACK WinProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam){

        switch (message){

        case WM_CREATE:{

            CreateWindow("BUTTON", "LED on", WS_VISIBLE | WS_CHILD | WS_BORDER, 20, 20, 70, 50, hWnd, (HMENU)1, NULL, NULL);
            CreateWindow("BUTTON", "LED off", WS_CHILD | WS_VISIBLE | WS_BORDER, 125, 80, 70, 50, hWnd, (HMENU)2, NULL, NULL);
            CreateWindow("BUTTON", "LED blink", WS_CHILD | WS_VISIBLE | WS_BORDER, 240, 140, 70, 50, hWnd, (HMENU)3, NULL, NULL);
            break;

        }

        case WM_COMMAND:{

        if(wParam == 1){

            system("avrdude");


        }

        if(wParam == 2){

            system("avrdude");


        }

        if(wParam == 3){

            system("avrdude");


        }

        if (wParam == IDA_CTRL_X){

            MessageBeep(message);

        }

            break;
        }

        case WM_DESTROY:{

            PostQuitMessage(0);
            return 0;
            break;

        }

        default:{

            return DefWindowProc(hWnd, message, wParam, lParam);

        }
        }


        }

这是我一直在使用的所有文件，但还有一个头文件，我在其中定义了一些小东西并添加了注释以供我记住，但它太大了，我定义的最重要的东西是消息MessageBox 和窗口为 WNDCLASS

我知道阅读所有这些内容需要付出很多努力，但我真的需要帮助，非常感谢大家。 =D

是的，如果你问我正在尝试从计算机制作一个程序来控制我将用微 Controller 制作的电路，但我还没有做十六进制程序或电路，这就是我开始的。

我相信你的错误在这里:

if (wParam == IDA_CTRL_X){
    MessageBeep(message);
}

当WM_COMMAND 的消息源是加速器时，wParam 的高位字是1，低位字是加速器标识符。如果是菜单，则高位字是 0，低位字是菜单标识符。 (参见 reference。)

所以你要做的是:

switch (message)
{
    case WM_COMMAND:
       wmId    = LOWORD(wParam);
       wmEvent = HIWORD(wParam);

       switch(wmId)
       {
         case IDA_CTRL_X:
            MessageBeep(message);
            break; 
       }
    break;
}
