Advanced: How to Create/Generate a New GUID using Vb.Net, C# and Vb.Script

Globally Unique Identifier or GUID is a 128-bit integer (16 bytes) that is used by some software applications across all computers and networks in order to provide a reference number which is unique or to identify a particular component. Because of this there's a very low probability that any two or more component has the same value.

GUID is also used in Windows Registry.

Example:

Internet Explorer {871C5380-42A0-1069-A2EA-08002B30309D}

Network {F02C1A0D-BE21-4350-88B0-7367FC96EF3C}

Computer {20D04FE0-3AEA-1069-A2D8-08002B30309D}

Vb Script

Set TypeLib = CreateObject("Scriptlet.TypeLib")
NewGUID = TypeLib.Guid
WScript.Echo(left(NewGUID, len(NewGUID)-2))
Set TypeLib = Nothing

C#

private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("GUID: {" + Guid.NewGuid().ToString()+ "}");
}

Visual Basic .Net 2008

Private Sub GenerateNewGUID()
Dim xGUID As String = System.Guid.NewGuid.ToString()
MessageBox.Show("{" & xGUID & "}")
End Sub

So, What's the use of this GUID to us? Sooner or later, As you study more and more about Registry Customizations... I'm sure you'll be reading this article again.
