键盘坏了一个键怎么办\c++全局快捷键

笔记本m坏了，所以找个不常用的键当转移键，按下转移键时将其拦截，模拟按下我们需要的按键。我这里用了右alt做转移键：

bool flag = TRUE;
LRESULT CALLBACK KeyboardProc(int nCode, WPARAM wParam, LPARAM lParam) {
    if (nCode == HC_ACTION) {
        KBDLLHOOKSTRUCT* p = (KBDLLHOOKSTRUCT*)lParam;
        if (p->vkCode == 165) { //右边的alt是165
            if (flag){
                keybd_event('M', 0, 0, 0); // Press the 'A' key
                keybd_event('M', 0, KEYEVENTF_KEYUP, 0);
                flag = !flag;
            }else{
                flag = TRUE;
            }
            return 1;
        }
    }
    return CallNextHookEx(NULL, nCode, wParam, lParam);
}

int main() {
    HHOOK hook = SetWindowsHookEx(WH_KEYBOARD_LL, KeyboardProc, GetModuleHandle(NULL), 0);

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

    UnhookWindowsHookEx(hook);
    return 0;
}
