About does not function reliably and often moves the mouse in unpredictable vectors.

I had a deep study on C++ sample source and found all the location(mean x,y) changed to device location such as int x = static_cast((0xFFFF * (center.x + position.x)) / screen_width); This means the X and y which is passed to the two function MoveMouseTo and MoveMouseBy are not correctly or unclear. So I did some change, it works perfectly. here is my change: Point point = ConvertDevicePoint(x, y); mouseStroke.X = point.X; mouseStroke.Y = point.Y; The function ConvertDevicePoint code is the following: private static Point ConvertDevicePoint(int x,int y) { int SH = Screen.PrimaryScreen.Bounds.Height; int SW = Screen.PrimaryScreen.Bounds.Width; return new Point(0xFFFF * x / SW, 0xFFFF * y / SH); } Then it works.

Thanks a lot for your code and help me a lot.

You succeed to simulate left and right click? The keyboard works great in contrast to the mouse that doesn't work at all.

Yes，it works correctly by the way aboved

I try your solution but, it still move the mouse to wrong location, for example: I have 2 monitors 1920x1080, if I use MoveMouseto(1300,700) - that is definitely inside the 1st monitor but it move the mouse to 2nd monitor and even wrong coordinate rather than 1300, 700.

Im repying to aswer my own question. If you have 2 monitors that have same resolution and their position (in side window display setting) is placed same row, like 2 x 1920*1080 You may want to try to devide the 0xFFFF by 2. if 2 monitor is placed same row then in the X, devide 0xFFFF by 2, and keep 0xFFFF of the Y. if 2 monitor is placed same column then in the Y, devide 0xFFFF by 2, and keep 0xFFFF of the X. You may want to make further maths if your case is 2 monitors have different res, or more than 2 monitors,... etc

It's up to your main monitor, please make sure the master and slave monitor is correct.
