• .NET Development Method to encrypt/decrypt passwords not working

  I had a post asking the best way to encrypt and decrypt passwords and I got a great response from David. He said to go to http://blogs.msdn.com/shawnfa/archive/2005/11/10/491431.aspx for help. I did, and came up with the following code (C#): public static string Encrypt( string data, string password) { if ( String .IsNullOrEmpty(data)) throw new ArgumentException ( "No data given" ); if ( String .IsNullOrEmpty(password)) throw new ArgumentException ( "No password given" ); // setup the encryption algorithm Rfc2898DeriveBytes keyGenerator = new Rfc2898DeriveBytes (password, 8); ...Show All

• Visual Studio Express Editions Power control of windows: How to reboot and wake from hibernate/standby?

• Visual Basic Is it possiable to create a C/C++ Style Macro VB.NET???

  Does any one know if it is possible to create a C/C++ style macro that can be used through the namespace as needed Example: The code below will be used in several classes throughout the namespace. I guess I could develop a base class to inherit from; however, some of the classes will need to inherit from other classes so the base class solution will not work. Your thoughts… # Region "Registry - Properties" Private mRegisrtyRoot As RegistryHive Private mRegistryControl As Boolean <Description("The root location that the controls attributes will be stored..."), D ...Show All

• SQL Server SQL Impesonate Logon Problem

    Hi. I am currently working on an ASP.NET application which has to log on to SQL using a specific windows user account. As far as I am aware the only way to do this is by adding the Integrated Security=true ; property to the connection string. If you specify a user id and password then it will try to log you in as a SQL user. Is this all correct   To be able to login to the SQL server we explicitly call the LogonUser function from the   advapi32.dll then open a SQL Connection using the Integrated Security=true property. When you look at SQL Profiler it seems that there is two logon calls made when the conne ...Show All
