C 自定义全局热键

我正在尝试为我的应用程序获取用户定义的全局热键。这是我的申请代码

user.rc

CONTROL         "", IDC_MHOTKEY, HOTKEY_CLASS, WS_TABSTOP, 91, 86, 68, 14

函数.cpp

    WORD wHotKey = SendDlgItemMessage(hwnd, IDC_MHOTKEY, HKM_GETHOTKEY, 0, 0);
    GLOBAL_HOTKEY= wHotKey;
    RegisterHotKey ( NULL, TURN_OFF_HOTKEY, HIBYTE(LOWORD(wHotKey)) , wHotKey);

   if ( messages.message == WM_HOTKEY && ( HIWORD ( messages.lParam ) == GLOBAL_HOTKEY) )
                        alert("Coming only for Single Key");

main.cpp

    WORD wHotKey = SendDlgItemMessage(hwnd, IDC_MHOTKEY, HKM_GETHOTKEY, 0, 0);
    GLOBAL_HOTKEY= wHotKey;
    RegisterHotKey ( NULL, TURN_OFF_HOTKEY, HIBYTE(LOWORD(wHotKey)) , wHotKey);

   if ( messages.message == WM_HOTKEY && ( HIWORD ( messages.lParam ) == GLOBAL_HOTKEY) )
                        alert("Coming only for Single Key");

此代码运行良好，仅当用户选择一个键，而当用户选择多个组合键（如CTRL+F8）时，此代码不起作用。

您需要将虚拟键与wHotKey值隔离开来：

RegisterHotKey ( NULL, 
    TURN_OFF_HOTKEY,  
    HIBYTE(LOWORD(wHotKey)),          // Modifiers
    LOBYTE(LOWORD(wHotKey))           // Virtual key
);

---

您需要将虚拟密钥从wHotKey值中隔离出来：

RegisterHotKey ( NULL, 
    TURN_OFF_HOTKEY,  
    HIBYTE(LOWORD(wHotKey)),          // Modifiers
    LOBYTE(LOWORD(wHotKey))           // Virtual key
);
