Step 1: Click Visual Basic to Cut-n-paste code into clsCInt.vb
Public Class clsCInt Public Sub Main() '**************************************************************************************** ' Purpose: Converts positive and negative numbers into Integer data type ' ' Syntax: CInt(expression) ' ' Parameter1: expression - -2,147,483,648 through 2,147,483,647; fractional parts are rounded ' ' Result: Integer - returns integer ' ' '**************************************************************************************** ' This example is from http://idealprogrammer.com Console.WriteLine("Example #1: CInt(expression)") Dim Integer1 As Integer = CInt(1.33) Console.WriteLine(Integer1) ' Returns 1 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #2: CInt(expression)") Dim Integer2 As Integer = CInt(-3.4) Console.WriteLine(Integer2) ' Returns -3 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #3: CInt(expression)") Dim Integer3 As Integer = CInt(5.5) Console.WriteLine(CInt(Integer3)) ' 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 myclsCInt As New clsCInt myclsCInt.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
