Cursor Position Stop Manually at Specific Point

Hi. try this method:
1- add using System.Runtime.InteropServices;
2- handle event of Mouse when you change the cursor position
3- create a If block and your condition must be cursor position.
4-when cursor is near to your favorite area then call following method:

[DllImport("user32.dll")]
        private static extern bool SetCursorPos(int xCoordinate, int yCoordinate);

xCoordinate and yCoordinate must be any point, out of limited area.
i hope this help you.
good luck
