Reading files line by line

[Expfighter]

This tutorial is for when you would like to make a cracker or something like that, and would like to read any file, putting content in a listbox or something

Ill be using:
VB.NET
Visual Studio 2013 Express (Other versions should be fine too)
A listbox for the contents
A .txt file (can be any extension)

Step 1
Create a new project
File > New Project Or Start menu > Create new project

Step 2
Make your layout / program
Im putting down a listbox and a button for opening the file

 

Step 3
Code your button to open a file
Drag a "OpenFileDialog" into your form, when you have a openfiledialog double click your button to open its code
This should be the code for your button:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    OpenFileDialog1.ShowDialog()
End Sub

Double click OpenFileDialog1 (In Form1's Design Tab)
Put this code in:
Replace (dot) with a dot, because MPGH thinks im trying to post links

'Create a streamreader (To read the file)
Dim streamreader As System(dot)IO.StreamReader = New System(dot)IO.StreamReader(OpenFileDialog1.FileName)
'Create a variable that keeps track of which line we are at
Dim line As Integer
'Let our user know were ready to load his file (Pure for information)
MessageBox.Show("Your file will be loaded!", "Info", MessageBoxButtons.OK, MessageBoxIcon.None, MessageBoxDefaultButton.Button1)
'Keep doing content till variable line is the same value as the amount of lines in the document
Do Until line = System(dot)IO.File.ReadAllLines(OpenFileDialog1.FileName).Length
        'Add the current line to the listbox
        ListBox1.Items.Add(streamreader.ReadLine())
        'Add 1 up to line
        line = line + 1
Loop

To Moderators: If you can edit this thread, just replace the (dot)'s with a real dot and remove the alert

Step 4
Test it out!
Hit that start button, and see what it does!
