Visual Basic untuk aplikasi

Visual Basic for applications adalah implementasi dari visual basic 6 (event-driven programming) microsoft dan Integrated Development Environment (IDE) nya yang terasosiasi.

Visual basic untuk aplikasi memungkinkan kamu untuk membuat user-defined function (udf) yaitu fungsi buatanmu sendiri, mengotomatisasi proses-proses dan mengakses API Windows dan fungsi low-level lainnya melalui DLL-DLL.

(sumber: http://en.wikipedia.org/wiki/Visual_Basic_for_Applications)


Visual basic untuk aplikasi memperluas kemampuan Word, Power Point, Excel ke taraf yang menyenangkan.

You want your software connect to the microsoft office programs?

Use COM and namespace
Because microsoft office contain code and dll

namespaces

What namespaces do they easier to organize the classes.

One namespace several different classes

The most basic concept of fluid

Instantiate object

Instatiating an object to a class is copying class's properties, copying class's method, copying class's sub module.
Contoh:
 Public Class Class1
    Public horizontal As Integer
    Public vertical As Integer

    Sub widen(ByVal scale As Integer)
        horizontal = horizontal + scale
        vertical = vertical + scale
    End Sub
End Class

Module Module1

    Sub Main()
        Dim square_a As Class1
        'next step, instatiate object square_a to class1
        square_a = New Class1
        square_a.horizontal = 1
        square_a.vertical = 1
        Console.WriteLine(square_a.horizontal & " " & square_a.vertical)
        square_a.widen(3)
        Console.WriteLine(square_a.horizontal & " " & square_a.vertical)
        Console.ReadLine()
    End Sub

End Module

Class

Untuk apa/bisa digunakan untuk apa?

Class bisa digunakan sebagai panduan pengisian. Seperti ngisi data di microsoft excel
Contoh perhatikan rani, sori perhatikan data berikut ini:

Nama	Umur	Suku	Status
Saya
Kamu
Dia

Begimana caranya?
1. Pertama defenisikan class
Public Class Orang
    'properties
    Public Umur As Integer
    Public Suku As String
    Public Status As String

End Class
 
2. Masukin saya sebagai orang, trus define(dim) umur saya, suku saya, status saya. Tampilkan status saya
Module Module1

    Sub Main()
        Dim saya As New Orang
        saya.Umur = 29
        saya.Suku = "Batak"
        saya.Status = "Belum Menikah"
        Console.WriteLine(saya.Status)
        Console.ReadLine()
    End Sub

End Module

Don't easily give up on your brain

Something may be difficult to grasp at first but should be easy enough if you stick at it.

Apa perbedaan sub procedure dengan function?

Simple, sub tidak return value, function return value.

Terminologi programming

Modules = class with super power
Class =
- is the blueprint
- container of related method
Contoh:
console
Object is an instance of a class

Looping

Components

Looping's components: (a = b x c)
(a) what to be looped(b)
(b) how many times (c)
- Unknown
- Known
= 
(c) result
(d) exit condition or stop condition

Which one?
If you know what to be looped and how many times you loop and what to be looped, you can use for.
If you don't know how many times you loop but know what to be looped and the what result you want, you can use while.

For: a, b, c
While: d

Examples
Python looping
- Python For
Example (Python)
>>> for i in range (0,2):
    print i

  
0
1
- Python While
 Example (Python):
>>> x=1
>>> while x < 3:
    x = x + 1
    print x

  
2
3

C Looping
- For
Usage: for (start counter; end counter; how to get to end counter)

Example:

- While
 This the most basic loop in C.
check first, do last.

Example:



- do..While
do.. While loop is just like while except the condition to test is behind
do first, check later

Preposition

AT / IT / ON

Syarat property

Property access must assign to the property
or use its value

Access-list technology
block certain packet with label ....
permit certain packet with label ....

Access-list standard: if you want examine only layer 3 use this type
Access-list extended: if you want to examine packet's at layer 3 (network, transport, application) and above use this type

NAT
translate certain packet with label ....
don't translate certain packet with label .....

Visual Basic

Creating ur first visual basic program
Notepad + command line compiler

Array
Create an array

Dim number(0 to 2) as integer
    number(0) = 1
    number(1) = 2


Function
Create function/method

1.Function that return a method but not take parameter
function sandirahasia() as String
    return "Aloha!"
end function

2. Function that return an output and take parameter

function sandirahasia2(ByVal name as String) as String
    return "Aloha" & name
end function


Call our function
Style 1:
sub main()
    dim my_string = sandirahasia() as String
    console.writeline(my_string)
end sub

Style2:
sub main()
    console.writeline(sandirahasia())
end sub

Style1 and style 2 the result is the same

While

Contoh 1: While sederhana

Module Module1

    Sub Main()
        Dim perutgue As Integer = 0
        While perutgue < 10
            perutgue = perutgue + 1
        End While
        Console.WriteLine("Gue kenyang!")
        Console.ReadLine()
    End Sub
End Module

If

Module Module1

    Sub Main()
        Dim lampu = Console.ReadLine()
start:
        If lampu = "merah" Then
            Console.WriteLine("Berhenti")
        ElseIf lampu = "kuning" Then
            Console.WriteLine("Hati-hati")
        ElseIf lampu = "hijau" Then
            Console.WriteLine("Maju")
        End If
        Console.ReadLine()
        If jawab == "y" Then GoTo start
        else console.readline()
        End if

    End Sub

End Module

Server application and client application

Server application
The application will "listen" on a designated port.
When client makes a connection request, the server can then accept request and thereby complete the connection.
Once the connection is complete, the client and server can freely communicate with each other.

Windows programming with C

Hungarian notation used for naming variables.
Hungarian notation requires that a variable be prefixed with an abbreviation of its data type.
Example:
putting letter "P" in front of a data type, or "p" in front of variable usually indicates that the variable is a pointer.

The letter LP stands for "long pointer"

Handle
Handle = a unique identifier
A handle is actually a pointer to a pointer to a memory location.
Handles are unsigned integers that Windows uses internally to keep track of objects in memory.

HWND
What is?
data types that keep tracks of the various object that appear on the screen.

How?
