Question

我捕捉到Windows鼠标移动事件并计算相对鼠标移动以将其发送到另一台PC。到目前为止一切顺利，效果很好。

但是，如果我在发送鼠标坐标（客户端）的屏幕上阻止鼠标移动或到达屏幕的一侧，则会出现第二个鼠标事件，它会被鼠标点击，然后将鼠标按回来。 / p>

我的第一个想法是记录相对运动并忽略每个“倒置”运动。但我正在寻找一种更好的方法。

首先我打电话：

Cursor.Position = new Point(0, 0);

    void HookManager_MouseMoveExt(object sender, MouseEventExtArgs e)
    {
        Logger.Log(String.Format("Pos: {0} {1} Delta: {2} {3}", e.X, e.Y, e.DeltaX, e.DeltaY), LogLevel.Info);

        if (hasControl)
            server.MouseMove(e.DeltaX, e.DeltaY, true); // send the coordinates to the client

        e.Handled = true; // Don't move the mouse
    }

现在我启动应用程序并将鼠标移动到左上方向。我只想收到负增量，但这种情况会发生：

Answer 1

我实际上无法回答您的问题，但您是否了解开源计划Synergy？

它会做你想要做的事情 - 也许你可以看一下提示的来源。

Answer 2

我不确定你要做什么的具体细节，但为什么不尝试将光标剪切到屏幕的一小部分并使其不可见。然后，每次检测到移动时，将客户端的光标移回到该剪切框的中心。所以你每次都在同一个屏幕上计算相对运动。

这就是PC模拟器的Bochs（几乎 - 它不会将光标剪切到窗口）。

Answer 3

根据box方法得到我的解决方案。 MouseSimulator.Position就是这样做：

        Cursor.Position = new Point(value, Y);

HookManager_MouseMoveExt是我的回调。 MouseEventExtArgs只是扩展了MouseEventArgs，增加了增量等功能。

        private bool ignoreNext = false;
        void HookManager_MouseMoveExt(object sender, MouseEventExtArgs e)
        {
            // Should we block all mouse interactions?
            if (Block) {
                e.Handled = true;
                return;
            }

            // Return if we should ignore the nex, because we made a big jump
            if (ignoreNext) {
                ignoreNext = false;
                return;
            }

            if (hasControl) 
            {
                // Lock the mouse to 100,100 : 200,200 and flip back to 150,150 if out of bounds
                if (e.X < 100 || e.X > 200 || e.Y < 100 || e.Y > 200) // Box leaved
                {
                    // If we leave the box, we set the position to the center 
                    // and set the event to handled otherwise the mouse is free
                    MouseSimulator.Position = new System.Drawing.Point(150, 150);
                    e.Handled = true;
                    ignoreNext = true;
                }

                // We moved fine, send the delta to the server
                // The MouseSimulator.Position change will not be visible yet.
                server.MouseMove(e.DeltaX, e.DeltaY, true);

            }

            Logger.Log(String.Format("Pos: {0} {1} Delta: {2} {3}", e.X, e.Y, e.DeltaX, e.DeltaY), LogLevel.Info);
        }
