PostMessage无法正确使用击键

Question

因此，基本上，我具有此功能，该功能每隔（在此处插入数字）毫秒释放一次W键，并且在按住W键时可以正常工作，但是由于某种原因，有时它在释放它后不会再次按该键，我真的不确定为什么会这样。是的，我也尝试过SendMessage。

我还需要PostMessage或SendMessage，因为我发送给它的进程没有注册SendInput击键。 SendInput会容易得多，但根本无法正常工作。这是我的代码：

struct extraKeyInfo
{
    unsigned short repeatCount;
    unsigned char scanCode;
    bool extendedKey, prevKeyState, transitionState;

    operator unsigned int()
    {
        return repeatCount | (scanCode << 16) | (extendedKey << 24) |
            (prevKeyState << 30) | (transitionState << 31);
    }
};

while (true)
{
    if (wtap_check && ((GetAsyncKeyState(87) & 0x8000) == 0x8000))
    {
        if (click_check && mouse_down)
        {
            extraKeyInfo lParam = {};
            //lParam.scanCode = MapVirtualKey(tagKBDLLHOOKSTRUCT::vkCode, MAPVK_VK_TO_VSC);

            lParam.repeatCount = 1;
            lParam.prevKeyState = true;
            lParam.transitionState = true;

            PostMessage(hwnd_outra_win, WM_KEYUP, (WPARAM)0x0057, lParam);

            std::this_thread::sleep_for(std::chrono::milliseconds(insertnumberhere));

            lParam.repeatCount = 0;
            lParam.prevKeyState = false;
            lParam.transitionState = false;

            //SendMessage(hwnd_outra_win, WM_KEYUP, 0, MAKELPARAM(x, y));
            PostMessage(hwnd_outra_win, WM_KEYDOWN, (WPARAM)0x0057, lParam);

            std::this_thread::sleep_for(std::chrono::milliseconds(insertnumberhere)));
        }
    }
}
