如何使用Process类打开便利贴

本文关键字：便利贴 何使用 Process | 更新日期: 2023-09-27 18:06:05

我想用过程类打开窗口便签，我已经知道如何为计算器和油漆做这件事，但不是便签。我把便利贴地址给它，它却打不开。我用的是64位的windows。(windows) 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace main
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            System.Diagnostics.Process.Start("mspaint");
            System.Diagnostics.Process.Start("calc");
            //sticky notes
            System.Diagnostics.Process.Start("C:''Windows''System32''StikyNot.exe");
        }
    }
}

它给出一个异常文件不能被找到，但是它存在于那个位置

如何使用Process类打开便利贴

你必须从C:'Windows'Sysnative'StikyNot.exe:

打开文件
System.Diagnostics.Process.Start(@"C:'Windows'Sysnative'StikyNot.exe");

由于x64系统上的System32文件夹是合成的，所以直接调用它不起作用。您必须使用Sysnative名称将路径映射到'real' system32文件夹

此位置适用于win8.1 64位

System.Diagnostics.Process.Start(@"C:'Windows'WinSxS'amd64_microsoft-windows-stickynotes-app_31bf3856ad364e35_6.3.9600.16384_none_de0517088d429664'StikyNot.exe");

如果它不适合你，你可以在你的windows驱动器中搜索StikyNot的其他位置

如果您想进一步尝试，您可以使用下面的程序作为参考。

下面是一个示例调用。实现逻辑如下:

public void NewNote(string someText)
{
var note = new StickyNote();
note.Activate();
note.Activated += (s, e) => { note.Signal(someText); };
}

    {  
        public bool MakeNewNote { get; set; }  
        public Process StickyNoteProcess { get; set; }  
    }  
}

你还需要添加一个应用程序设置条目。

<?xml version="1.0" encoding="utf-8" ?>  
<configuration>  
  <appSettings>  
    <add key="SendKeys" value="SendInput"/>  
  </appSettings>  
</configuration>
