Step 1: Click Visual Basic to Cut-n-paste code into clsCSByte.vb
Public Class clsCSByte Public Sub Main() '***************************************************************************************** ' Purpose: Converts positive and negative numbers into SByte data type ' ' Syntax: CSByte(expression) ' ' Parameter1: expression - -128 through 127; fractional parts are rounded. ' ' Result: SByte - Signed Byte ' ' '**************************************************************************************** ' This example is from http://idealprogrammer.com Console.WriteLine("Example #1: CSByte(expression)") Dim Long1 As Long = CSByte(1.33) Console.WriteLine(Long1) ' Returns 1 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #2: CSByte(expression)") Dim Long2 As Long = CSByte(-3.4) Console.WriteLine(Long2) ' Returns -3 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #3: CSByte(expression)") Dim Long3 As Long = CSByte(5.5) Console.WriteLine(CSByte(Long3)) ' Returns 6 'Prevent console from closing before you press enter Console.ReadLine() End Sub End Class |
Step 2: Click Visual Basic to Cut-n-paste code into Module1.vb
Module Module1 Sub Main() Dim myclsCSByte As New clsCSByte myclsCSByte.Main() End Sub End Module |
Prerequistes:
- Install Visual Basic (Express or Standard Edition)
- Install SQL Server Express
- Download Northwind and pubs Database
- Attach Northwind Database to Databases in Sql Express
- 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
