I catch the windows mouse movement events and calculate an relative mouse movement to send it to another pc. So far so good, works well.
我抓住了Windows鼠标移动事件并计算了相对鼠标移动以将其发送到另一台PC。到目前为止这么好,效果很好。
But if I block the mouse movement on the screen that is sending the mouse coordinates (the client) or reach one side of the screen, there is a second mouse event fired by the windows api, that snaps the mouse back.
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,则会出现由windows api触发的第二个鼠标事件,即将鼠标按回。
My first thought is to record the relative movements and ignore every "inverted" movement. But I'm looking for a better method.
我的第一个想法是记录相对运动并忽略每一个“倒置”运动。但我正在寻找一种更好的方法。
First I call:
首先我打电话给:
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
}
Now I start the app and move the mouse to the upper left direction. I only want to receive only negative deltas, but this happens:
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,但这种情况发生了:

I can't actually answer your question, but are you aware of the open-source program Synergy?
我实际上无法回答你的问题,但你知道开源程序Synergy吗?
It does what you're trying to do - perhaps you could take a peek at the source for hints.
它会做你想要做的事情 - 也许你可以看一下提示的来源。

I'm not sure the specifics of what you're trying to do, but why not try clipping the cursor to a small part of the screen and making it invisible. Then every time you detect movement, move the client's cursor back to the center of that clipped box. So you're calculating relative movement from the same on-screen point every time.
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。因此,您每次都要从同一屏幕上的点计算相对移动。
This is what Bochs, the PC emulator does (almost--it doesn't clip the cursor to the window).
这就是PC模拟器Bochs所做的事情(几乎 - 它不会将光标剪切到窗口)。

Got my solution, based on the box method. MouseSimulator.Position just do:
得到了我的解决方案,基于box方法。 MouseSimulator.Position就是:
Cursor.Position = new Point(value, Y);
HookManager_MouseMoveExt is my callback. MouseEventExtArgs are just extended MouseEventArgs, added features like the deltas.
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);
}
