[Tutorial]Convert Bits 2 Bytes

Convert Bits to Bytes and Bytes to Bits

In this tutorial we will learn how to make a Program to convert bytes to bits and Vice versa,

As always , create a new vb.net project
Name it ConvertBits (or whatever you like)
On your form you are going to add

2 Texboxes
2 Radio Controls
1 CheckBox
1 Label
2 Buttons

Arrange them however you like (you can use the below image for guidance)

Set the Text for the following controls to

Radio Control 1 - To Bits
Radio Control 2 - To Bytes
CheckBox - Abbreviated
Button 1 - Convert
Button 2 - Exit

Change the name of your label to lblbit

It should look something like this

As always here is the code, I have noted everything you will need to know in order to learn from this example

Code:

Option Strict On
Imports System.Convert

Public Class Form1
    'True = Bytes to bits
    'False = bits to Bytes

    Dim objBitByte As New Converter()

    Private Sub ButtonX1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX1.Click
        If CheckBox1.Checked = False Then
            'Unabbreviated output
            TextBox2.Text = objBitByte.Convert(CLng(TextBox1.Text), RadioButton1.Checked)
        Else
            'Abbreviated output
            TextBox2.Text = objBitByte.Format(CLng(objBitByte.Convert(CLng(TextBox1.Text), RadioButton1.Checked)), RadioButton1.Checked)
        End If
    End Sub

    Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
        Me.Close()

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub

    Private Sub RadioButton2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton2.CheckedChanged
        'Change lblBit to display "Bytes" when converting to bits
        If RadioButton1.Checked = True Then
            lblbit.Text = "Bytes"
        End If
    End Sub

    Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged
        'Change lblBit to display "bits" when converting to Bytes
        If RadioButton2.Checked = True Then
            lblbit.Text = "bits"
        End If
    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        If Not IsNumeric(TextBox1.Text) Then
            TextBox1.Clear()
        End If
    End Sub
End Class
Public Class Converter

#Region "Methods"

End Function in Region may give errors, pay no mind to it.

' As always you may have to change the control names to make this work for your program
' Didn't include the source for this one yet, I will sometime soon
' Just in a rush this morning

Is there any difference between a radiobutton and a checkbox? just wondering

In a sense, though the outcome can be achieved using either or.

*radiobuttons only allow one decision
checkboxs allow the selction of mulitiple options.

Example:

RadioButton
-----------
Gender = o Male o Female
Animal = o Cat o Dog

CheckBox
--------
Favorite programming languages
o Visual Basic o C++ o Assembly

here you can select all 3
