我捕获 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。到目前为止一切顺利,效果很好。
但是,如果我阻止发送鼠标坐标(客户端)的屏幕上的鼠标移动或到达屏幕的一侧,则 Windows api 会触发第二个鼠标事件,该事件会将鼠标弹回。
我的第一个想法是记录相对运动并忽略每一个“倒转”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将鼠标移动到左上角方向。我只想接收负增量,但会发生这种情况:
