如何将相对鼠标移动发送到另一台电脑

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电脑。迄今为止非常好，运作良好。

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，则会发生由窗口api触发的第二个鼠标事件，即将鼠标移回。

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，并把鼠标移动到左上角的方向。我只希望接收仅负增量，但这种情况发生：

Answer 1

得到了我的解决方案，基于箱子的方法。 MouseSimulator.Position只是做：

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

HookManager_MouseMoveExt是我的回调。 MouseEventExtArgs只是扩展MouseEventArgs，增加了像增量一样的功能。

 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); 
     }

我不知道，你正在试图做什么的细节，但为什么不尝试裁剪光标移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该修剪框的中心。所以你每次都要从相同的屏幕点计算相对移动。

这就是PC模拟器Bochs所做的（几乎 - 它不会将光标剪切到窗口）。

我实际上不能回答你的问题，但你知道开源程序Synergy？

它做你正在做的事 - 也许你可以偷看提示的来源。
