Public Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim fName As String = "Simon"
      Dim mName As String = "Jake"
      Dim lName As String = "Harrows"

      ' we want to simply quickly add this person's name together

      ' because we want a name to appear with a space in between each name, 
      ' put a space on the front of the middle, and last name, allowing for
      ' the fact that a space may already be there
      mName = " " + mName.Trim()
      lName = " " + lName.Trim()

      ' this line simply concatenates the two strings
