Hi I am working on a windows Application. I want to store the Passwords in SQL server 2005 in encrypted format. How to do this?

And Again how to validate the credentials with an user input

If you do not need to retrieve the password that was stored, you can use a hash version of it. When a user enters his username and password in your application, you would hash the password and compare it to the hash that you have in the database to see if it matches.
If you need to have a way to retrieve the password, you cannot use hash, you need to apply an encryption algorithm to be able to decryt it later.

You have two types of hashes you can do, MD5 or SHA1. The following method gives you a SHA1 hash string of the string it receives.

public string CreateSHA1PasswordHash(string inputString)
{
	SHA1 sha1 = new SHA1CryptoServiceProvider();  
	byte[] buffer = Encoding.UTF8.GetBytes(inputString); 
	byte[] cipher = sha1.ComputeHash(buffer);
	StringBuilder sb = new StringBuilder(cipher.Length * 2);  
	for (int i=0; i<cipher.Length; i++)  
           sb.Append(cipher[i].ToString("x2"));  
	return sb.ToString();
}

Hope this helps.

Typically, you'd use the Cryptography namespace, pick an algorithm, salt your password and pass a hash into SQL Server. Then you'd pass the user input, also salted and hashed, to a stored proc that returns if the username/password combination is valid

Hello...

Are there any possibilities to get all available domains in network ?
(Just like the login windows. The user can choose domain from DropDownList)

Thanks...

Installing a windows service on a windows 2003 server

Hi,

I have a problem installing my windows service on a windows 2003 Server, user is a administrator.
I have no problem installing the same service under Windows XP.

I get the following error message:

An exception occurred while trying to find the installers in the c:\program files\archivetool\archivetool.exe assembly.
System.Reflection.ReflectionTypeLoadException: One or more of the types in the assembly unable to load.
Aborting installation for c:\program files\archivetool\archivetool.exe.
Rolling back assembly 'c:\program files\archivetool\archivetool.exe'.
Affected parameters are:
assemblypath = c:\program files\archivetool\archivetool.exe
logfile = c:\program files\archivetool\archivetool.InstallLog

Searching internet forum I get the idea that something with the .net Framework 1.1 ( which is the framework I need to run my service) is wrong. But I checked that the newest version of the .net Framework 1.1 for windows 2003 server is installed.

Does any of you have an idea? Iam really stuck.

thanks.

I m just giving u hints

1. First of All Applly Query to Take out the records.

2.Then fill them in a particulary lable by using
lable1.text="xyz";

for(index=0; index<=4000; index++)<br />
{<br />
label1.Location.X = index;	//This Produces<br />
lable1.Location.Y = index;	//marquee effect<br />
}

Do this for each product

I'm really not sure how to respond to this, and still be polite. I think it's best that I just suggest that it's great you want to help, but while I generally disapprove of giving people full code solutions for what is obviously homework, I'd also say that if you're going to give someone code, try testing it first, the sort of person who is looking to be given code, isn't likely to be capable of debugging it.
