动态改变鼠标速度 [英] Dynamically changing Mouse speed

问题描述

伙计们，我有一个C#Winforms应用程序，该窗体内部有一个面板.我想做的是，每当鼠标指针进入该面板时，我都希望将鼠标的移动速度降低50％.一旦指针移到该面板之外，我想使鼠标速度恢复正常的100％速度.如何在C#中完成此操作?

Guys, I have a C# Winforms application with a panel inside the form. What I want to do is, whenever the mouse pointer enters this panel, I want to slow the movement speed of the mouse by 50%. Once the pointer moves outside this panel, I want to speed of the mouse to resume normal 100% speed. How can I accomplish this in C#?

这是文章中的代码:

using System;
using System.Runtime.InteropServices;

namespace MouseSpeedSwitcher
{
    class Program
    {
        public const UInt32 SPI_SETMOUSESPEED = 0x0071;

        [DllImport("User32.dll")]
        static extern Boolean SystemParametersInfo(
            UInt32 uiAction, 
            UInt32 uiParam, 
            UInt32 pvParam,
            UInt32 fWinIni);

        static void Main(string[] args)
        {
            SystemParametersInfo(
                SPI_SETMOUSESPEED, 
                0, 
                uint.Parse(args[0]), 
                0);
        }
    }
}
