Download Dell Service Tag Finder: Source | Executable

This is was possible using Windows Management Instrumentation and if you are interested in pulling other information from your computer I recommend you read up on it. For this example I used the Win32_BIOS Class, but you can find all the WMI Classes here.

Preview of Source:

        String dellServiceTag;

        private void Form1_Load(object sender, EventArgs e)
        {
            //Load Service Tag
            ManagementClass wmi = new ManagementClass("Win32_Bios");
            foreach (ManagementObject bios in wmi.GetInstances())
            {
                dellServiceTag = bios.Properties["Serialnumber"].Value.ToString().Trim();
            }
            Display.Text = dellServiceTag;
        }

Notes:

This application requires the .NET Framework or you may receive application errors.

The service tag is pulled from the BIOS so if you ever had your motherboard replaced and the service tag was not reset it will be blank.

using System.Threading;

    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        { 

            bool createdNew = true;
            using (Mutex mutex = new Mutex(true, "SignleInstance", out createdNew))
            {
                if (createdNew)
                {
                    Application.EnableVisualStyles();
                    Application.SetCompatibleTextRenderingDefault(false);
                    Application.Run(new Form1());
                }
            }

        }
    }

Download Single Instance Application Source Code

I still don’t get why in Visual Studio in VB.NET one could click make single instance application, but that same feature doesn’t exist in C#? Don’t all .NET languages just get compiled to the CIL in the end?

LyricWiki is a free site which is a source where anyone can go to get reliable lyrics for any song, from any artist, without being hammered by invasive ads.

At this point you are probably thinking to yourself the same thing I did “Great, but where do I start?” So today I am writing a step by step tutorial on how to use Lyric wiki in your .NET program.

Creating a simple lyric demo program:

Step 1: Create the Form

Open visual studio and setup your form to look similar to mine.

Adding the web service:

Because LyricWiki offers a web service, you will want to add it to your program as a web reference. Right click on your solution and select add a web reference, or in .net 3.5 add a service reference -> then go to advance and add a web reference. The service’s URL is http://lyricwiki.org/server.php?wsdl you will want to add it like below if you press go you should see the available methods.

Adding a Web Reference

Writing the code:

Double click on your button on the form and let’s right some code to handle the lookup.

Add this to the top of your code:

using LyricsLookup.org.lyricwiki;

Then add this to the button clicked method:

private void LyricsButton_Click(object sender, EventArgs e)

{

LyricWiki wiki = new LyricWiki();

LyricsResult result;

string artist = artistTextBox.Text;

string song =   SongTextBox.Text;

if(wiki.checkSongExists(artist,song))

{

result = wiki.getSong(artist, song);

Encoding iso8859 = Encoding.GetEncoding("ISO-8859-1");

LyricsRichTextBox.Text = Encoding.UTF8.GetString(iso8859.GetBytes(result.lyrics));

}else{

StatusLabel.Text = "Lyrics not found in database";

}

}

Then run and test.
