QQ对战平台登录器

好不容易有个周末，想联机打一把魔兽。可QQ对战平台上我想进去的几个房间都是人满为患，没办法，只好写个工具挤房间了。

原理很简单，就是调用keybd_event和mouse_event来不停的发鼠标点击（房间登录）和回车消息（登录失败确认）。代码如下：

class QQGameLoger
{
    void TryLogIn()
    {
        ClickKey(Keys.Enter);
        ClickLeftMouse();
    }

    bool enabled = false;
    public bool Enabled
    {
        get
        {
            return enabled;
        }
        set
        {
            if (value)
                Start();
            else
                Stop();
        }
    }

    public void Start()
    {
        if (enabled)
            return;

        enabled = true;
        System.Threading.ThreadPool.QueueUserWorkItem(x =>
        {
            try
            {
                while (true)
                {
                    if (!Enabled)
                        break;

                    System.Threading.Thread.Sleep(200);
                    TryLogIn();
                }
            }
            catch (Exception)
            {
                enabled = false;
            }
        });
    }

    public void Stop()
    {
        enabled = false;
    }

    void ClickKey(Keys key)
    {
        const int ExtendKey = 0x1;
        const int KeyUp = 0x2;
        keybd_event(key, 0x45, ExtendKey, 0);
        keybd_event(key, 0x45, ExtendKey | KeyUp, 0);
    }


    [DllImport("user32.dll")]
    static extern void keybd_event(Keys key, byte bScan, uint dwFlags,
     uint dwExtraInfo);

    [DllImport("user32.dll")]
    static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData,
     int dwExtraInfo);

    [Flags]
    public enum MouseEventFlags
    {
        LEFTDOWN = 0x00000002,
        LEFTUP = 0x00000004,
        MIDDLEDOWN = 0x00000020,
        MIDDLEUP = 0x00000040,
        MOVE = 0x00000001,
        ABSOLUTE = 0x00008000,
        RIGHTDOWN = 0x00000008,
        RIGHTUP = 0x00000010
    }

    void ClickLeftMouse()
    {
        mouse_event((uint)MouseEventFlags.LEFTDOWN, 0, 0, 0, 0);
        mouse_event((uint)MouseEventFlags.LEFTUP, 0, 0, 0, 0);
    }
}

整个代码用.net实现，虽然调用api不如c++来得直接，但是要节省不少设计和调试时间。整个工具从设计到调试完成也没花多少时间，大部分时间花在查询和实验api的用法上了。

使用这段代码也很简单，只要把鼠标放在想登陆的房间上，注册个全局快捷键来调用start和stop即可。这个功能也集成在我以前写的魔兽鼠标限定的小工具上了。
