[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

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

Hope This helps Someone

' 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
