VB.NET Tutorial 42 - Reading Text Files (Visual Basic 2008/2010)

This is a pretty simple and short tutorial that will teach you how to take the text from a text file and write it into a textbox using StreamReader. I probably should have created this tutorial a long time ago but never really thought about it.

For more information, check out the website:

@JasonBoomGames code w/e button you were gonna code and then click on the FORM's properties, under Misc you will see "accept button". whatever u select as accept button will run when the user presses enter.

nice tutorials, is there much to adding a browse button?

@ShayAxelod22 you split them with a : or some symbol and 0 would be the first text before the symbol and 1 would be the etc so you split the stuff with your symbol and make new strings using .split(0) or something like that

Hey, great tutorial but I have a few questions...
1. is there a way to only read the first line of the text file, then in a new textbox read the second line?
2. is it possible to keep the file location the same every time so the user does not have to type it in?
any help would be awesome, thanks

Hi this is a really great tutorial like all of your's are, but I'm curious what would I have to change if I want it to automatically read the same file path every time? See I wrote a script for our domain controller that writes the logon name/machine name/IP address to a text file on a network share. So I want a vb program that once opened constantly reads that text file? If another user logs on and adds a line to the file, I want to see it live. Or I could write them as individuall files? Help!

@8o8inSquares I've got them to be in the textbox but I don't really know how to use them

[oinSquares]

How do I read variables from the text file like:
var1=85
var2=stringLol

and use them?

if i want to read file containing nos in two columns and want to save the nos in a[i] and b[i] line by line ....how to do it?

[darkstars]

You'd need to pull the file, then read it. Really simple actually, Just look up FTP Visual Basic. Its as simple as requesting the file with the FTP credentials. I used that method as a makeshift update system. It pulled a file from the server, checked its version, and deleted it. That way I don't need to integrate live applications and server crap.

how do you make this support url files?
