Generate A Strong Name Key File

I am a Newbie to programming and databases and would like to create a simple program for doing full text searching on a SQL database.

I have downloaded and installed Visual Basic 2005 Express, Web Developer 2005 Express, and SQL Server 2005 Express. I have watched several hours of video tutorials and done numerous tutorials. I feel I am making progress and having a lot of fun. My machine is running XP home edition.

I have found the following resource that looks like a good place for me to start with creating a full text search program:

€œSQL Server 2005 Books Online
Item Finder Sample
http://msdn2.microsoft.com/en-us/library/ms160844.aspx

However I am stuck at the beginning with trying to €œgenerate a strong name key file.€? I don€™t know how to €œopen a command prompt€? (I did confess to being a Newbie!!). I searched the database for this forum and found a relevant thread stating that €œSQLCMD is the command-line utility for SQL Server and is included with SQL Server 2005 Express Edition.€? I found the SQLCMD program on my computer but when I opened it, it does appear to provide the options listed below in the tutorial (i.e., €œclick start,€? €œPoint to all programs,€? etc.).

Initially here is what I need based on the first section of the tutorial:

Building the Sample

If you have not already created a strong name key file, generate the key file using the following instructions.

To generate a strong name key file

Open a Microsoft Visual Studio 2005 command prompt. ClickStart, point toAll Programs, point toMicrosoft .NET Framework SDK 2.0, and then clickSDK Command Prompt.

-- or --

Open a Microsoft .NET Framework command prompt. ClickStart, point toAll Programs, point toMicrosoft .NET Framework SDK 2.0, and then clickSDK Command Prompt.

Use the change directory command (CD) to change the current directory of the command prompt window to the folder where the samples are installed.
Note:
To determine the folder where samples are located, click theStartbutton, point toAll Programs, point toMicrosoft SQL Server 2005, point toDocumentation and Tutorials, and then clickSamples Directory. If the default installation location was used, the samples are located in <system_drive>:Program FilesMicrosoft SQL Server90Samples.

At the command prompt, run the following command to generate the key file:
sn -k SampleKey.snk

Important:
For more information about the strong-name key pair, see "Security Briefs: Strong Names and Security in the .NET Framework" in the .NET Development Center on MSDN.

How do I complete this initial step of generating a strong name key file for the tutorial? I guess I am missing something simple and once I get past this I will be able to complete the tutorial. Any help will be greatly appreciated.
