3- Open “Network and Internet”
4- Open “Network and Sharing Center”
5- Click “setup a new connection or network”
6- Setup “create an ad hoc network”

So, you thought that you have by now become comfortable with the Surface Area Configuration Tool in SQL Server 2005 and are ready to do the configuration once you install SQL Server 2008.  Well, the tool does not exist anymore in SQL Server 2008 and has been added to the deprecated feature list. As you will recall, we used to use SAC for doing configuration for services & connections as well as for features.

So, how can you go about making configuration changes via the GUI?  It has been divided up into different tools now:

Instance and Database Engine Features:

This will now be done through SSMS (SQL Server Management Studio).  Right click on the instance and select Facets as shown in the image below:


Once you select it, the next screen that you will get is this one:

And you can pick and choose what you want to confgure.  Surface Area configuration is one of the facets.

Another thing that you would note at the bottom right hand side is “Export Current State as Policy” – using this, one can then use that policy across the group in order to have a consistent environment.

by in .NET, C#, Console, Hacks, Security, Windows

one of the most famous topics is how we can know the current user credential like

user name, Groups, Authentication Type   (I hope to find a way to know password :-) )

check this code

Console.WriteLine("AuthenticationType =" + WindowsIdentity.GetCurrent().AuthenticationType);
Console.WriteLine("Name ="+WindowsIdentity.GetCurrent().Name);
Console.WriteLine("Groups :");
foreach (IdentityReference ir in WindowsIdentity.GetCurrent().Groups)
{
          Console.WriteLine(ir.Translate(typeof(NTAccount)).ToString());
}

and this a another way to get Windows Identity

WindowsPrincipal p = Thread.CurrentPrincipal as WindowsPrincipal;
(p.Identity as WindowsIdentity)

and for ASP.Net

HttpContext.Current.User.Identity

Puzzle Game using WPF

After Spending my weekend to Read about WPF

The Windows Presentation Foundation (or WPF), formerly code-named Avalon, is a graphical subsystem in .NET Framework 3.0 (formerly called WinFX), which uses a markup language, known as XAML, for rich user interface development. WPF is included with Windows Vista and Windows Server 2008, and is also available for Windows XP Service Pack 2 or later, and Windows Server 2003. It provides a consistent programming model for building applications and provides a clear separation between the user interface and the business logic. A WPF application can be deployed on the desktop or hosted in a web browser. It also enables rich control, design, and development of the visual aspects of Windows programs. It aims to unify a number of application services: user interface, 2D and 3D drawing, fixed and adaptive documents, advanced typography, vector graphics, raster graphics, animation, data binding, audio and video. Although Windows Forms will continue to be widely used, and Microsoft has created only a few WPF applications, the company promotes WPF for line-of-business applications. Future Microsoft software will be built on WPF; for example, the code editor in Visual Studio 2010 has been rebuilt on WPF.

it is really interesting technology and it will change the way to Design GUI for Standalone and Websites Solutions.

I have to read more about its concepts and how it is really work to make my Small Puzzle Game
