Self-Taught programmer in need of some basic help...

I'll start out by saying that I'm fairly comfortable programming in VB (2005) but, since I'm self-taught, I don't know the proper terminology for most things, so I apologize in advance if this is hard to understand.

Should be an easy question today: I have a fairly simple application and I now need to store some data to a .txt document. From what I read, it should be easy, but I can't seem to get it working right now.

If the file path of the text document was: C:\Program Files\Poop.txt, how could I write the value of a variable (let's say the variable is called "intAge") to this text document? The simplest way would be awesome.

Thank you in advance,
Cameron

Thread moved from the 'VB6 and Earlier' forum to the 'VB.Net' (VB2002 and later) forum


This way is rather simple:

Code:

---

My.Computer.FileSystem.WriteAllText("C:\Program Files\Poop.txt", intAge.ToString, False, System.Text.Encoding.Default)

---

Imports System.IO
Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim writer As StreamWriter = New StreamWriter("C:\VBForums.txt", True)
        writer.WriteLine("VBForums")
        writer.Close()

Awesome. Thank you guys so much.

Instead of making a new post, I think I'll bump this one since this is all part of one larger question...

How would I then go back into that text document, check to see what word (or number) is on line...let's say Line 25? How could I store the contents of Line 25 to a variable or how could I reference the contents of Line 25 for something like an If/Then Statement or to change the text in a Text Box to the contents of Line 25?


Thanks again for all of your continuous help,
Cameron

vb Code:

' If you wanted to get all the lines into an Array 
' Dim lines() As String = IO.File.ReadAllLines("C:\MyFile.txt")
' To view line 25 you would reference index 24 (we start from 0)
' MessageBox.Show(Lines(24))
 
' Here we create a variable by reading all lines into an array
' and referencing index 24. Line 25
Dim line As String = IO.File.ReadAllLines("C:\MyFile.txt")(24)
Me.txtMyTextBox.Text = line

Great.

So I could then do something like this?:

Code:

---

Dim line As String = IO.File.ReadAllLines("C:\MyFile.txt")(24)

If line = "UR A WINRAR" Then

'Carry Out Main Command

Else

'Carry Out Secondary Command

End If

You need to try it to see ;) But yes it will.

Thanks guys. I think I'm in business...!
