SendInput到chrome窗口：CTRL + n不起作用

Question

我正在尝试向Chrome发送一些键盘输入并让它打开一个新窗口

int NewWindow(const char *url)
{
    HWND chrome = FindWindow(L"Chrome_WidgetWin_1", NULL);
    if (chrome == NULL)
    {
        puts("Can't find chrome window");
        return -1;
    }

    if (! SetForegroundWindow(chrome))
    {
        puts("Can't move chrome to foreground");
        return -2;
    }

    INPUT *inputs = new INPUT[2];

    inputs[0].type           = INPUT_KEYBOARD;
    inputs[0].ki.wVk         = VK_CONTROL;
    inputs[0].ki.wScan       = 'n';
    inputs[0].ki.dwFlags     = KEYEVENTF_UNICODE;
    inputs[0].ki.time        = 0;
    inputs[0].ki.dwExtraInfo = GetMessageExtraInfo();

    inputs[1].type           = INPUT_KEYBOARD;
    inputs[1].ki.wVk         = VK_CONTROL;
    inputs[1].ki.wScan       = 'n';
    inputs[1].ki.dwFlags     = KEYEVENTF_UNICODE | KEYEVENTF_KEYUP;
    inputs[1].ki.time        = 0;
    inputs[1].ki.dwExtraInfo = GetMessageExtraInfo();  

    int keystrokes_sent = SendInput(2, inputs, sizeof(*inputs));
    fprintf(stderr, "Send %d keystrokes\n", keystrokes_sent);
    delete [] inputs;

    return 0;  
}

当我执行它时，chrome窗口被移动到前景但没有任何改变。

有什么想法吗？我正在使用版本58.0.3029.110
