Question

我正在尝试创建一个空窗口，它在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风格，然后转为正常，然后再次悬停，然后正常。在www.amazon.com上，当我模拟悬停链接时（“今日特卖”），链接闪烁。

我认为有一种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mouseevent一起使用。等待最好的解决方案〜 orz

当我真正悬停链接时，上面是间谍++日志。并且模拟与真实消息相同

Answer 1

这是因为IE调用WindowFromPoint（）来获取前台窗口，如果结果不是你的IE窗口，它就知道你的鼠标不在那里。一种可能的解决方案是挂钩API。

Answer 2

您的代码没有任何问题。问题在于Windows发送消息的方式。

当您移动鼠标时，Windows会将消息发送到屏幕上的每个窗口。因此，无论何时将WM_MOUSEMOVE消息发送到IE窗口句柄，Windows本身都会发送另一条消息，告知鼠标不在那里。

所以这是一场小小的比赛......

如何从一个窗口到另一个窗口模拟mousemove事件？
