Winapi 如何模拟从一个窗口到另一个窗口的mousemove事件？

我试图创建一个空窗口，该窗口在WinProc中处理WM_MOUSEMOVE消息：

case WM_MOUSEMOVE:
    {
        HWND otherHwnd = HWND(0x000608FC);
        POINT pt = {LOWORD(lParam), HIWORD(lParam)};

        ClientToScreen(otherHwnd, &pt);
        PostMessage(otherHwnd, WM_TIMER, WPARAM(4096), 0);
        PostMessage(otherHwnd, message, wParam, lParam);
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y));
        SendMessage(otherHwnd, WM_SETCURSOR, WPARAM(otherHwnd), (LPARAM)MAKELONG(HTCLIENT, WM_MOUSEMOVE));
        break;
    }

我希望我可以在IE中悬停hyberlink，但结果是hyberlink只能在很短的时间内显示为悬停样式，然后它变为正常，然后再次悬停，然后正常。 在www.amazon.com上，当我模拟悬停链接（“今日交易”）时，链接正在闪烁

我认为有一个更好的方法可以做到这一点，即使IE窗口被其他一些窗口覆盖，它也可以使IE与MouseeEvent一起工作。等待最佳解决方案~ 奥兹

上面是我真正悬停链接时的spy++日志。 模拟结果与真实信息一致

您的代码没有问题。问题在于Windows发送消息的方式

当您移动鼠标时，Windows会向屏幕上的每个窗口发送消息。因此，每当您向IE windows句柄发送

WM_MOUSEMOVE

消息时，windows本身就会发送另一条消息，告诉您鼠标不在那里

---

这是一个小竞赛…

这是因为IE调用WindowFromPoint（）来获取前景窗口，如果结果不是你的IE窗口，它知道你的鼠标不在那里。一个可能的解决方案是挂接API

我无法使用spy++看到另一条消息。我试图捕捉Webbrowser的图片，并在我的空窗口中显示它，它工作了。通过我拍摄的图片，发送消息仍然使不稳定的悬停，即使我使空窗口和Webbrowser窗口处于同一位置。
