        Dim Short1 As Short = CShort(1.33)
 
        Console.WriteLine(Short1) ' Returns 1
 
        'write blank line to make output easier to read
        Console.WriteLine()

        myclsCShort.Main()
 
 
 
    End Sub
 
End Module

Prerequistes:

  1. Install Visual Basic (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

Notes:

  • Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
  • You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.vb
