TreeView Data Save > TextFile

Mar 11, 2010

I've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)

Write To A Textfile From Listbox?

Aug 28, 2011

It may seem noobish but, I've been try forever! I've been postponing a database project for like 3 years and I finally come to some solutions except for when it deletes an Item from the list. On form load, the listbox generates data from a text file (we'll call text1) which has data in it. For every line of data in that text file (text1), there is a text file (text2) in a 2nd folder.

For example, there may be, in text1, a line named "Hi". In the 2nd folder there is a text file named "hi.txt" Another line (say the next line under 'Hi') is written as "Hello world", there will be a file in the second folder called hello world.txt"

May seem confusing but it works well. My problem is making that 1st text file that has ALL of the data that loads into the listbox, be rewritten over with the new data in the listbox OR remove a certain line of from the text file.

Read Contents Of Textfile Into Listbox?

May 15, 2009

I'm trying to place the contents of a text file (just a list of names) into a list box when the form loads.

My code currently looks like this:

Imports System.IO
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

[Code].....

I can get the names into the list box, but they're all on one line. I thought about using a For...Next loop to read the contents of the text file, but I got into all sorts of trouble; do I need an array with that method? So I've got back to the code I originally had.

Reading Strings In Textfile And Adding Them In A Listbox?

Jan 6, 2012

I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox

Here is my

scorelist = New ArrayList
reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")

Save Textbox To Textfile With Proper VbNewLine?

Dec 16, 2009

when you have a textbox and you save the contents to a file : My.Computer.FileSystem.WriteAllText(SaveFileDialog1.FileName, TextBox1.Text, False, System.Text.Encoding.ASCII) and you open the file in notepad, you will see instead of multiple lines one long line and where the vbNewLine should be, a small square symbol.

the simple reason is: even if you write a vbNewLine or vbCrLf to your textbox, it will be reduced to vbLf so when writing the textbox.text to a textfile it only writes the vbLf where you would like to have a vbCrLf

so all you have to do is replace the vbLf with vbNewLine :

My.Computer.FileSystem.WriteAllText(SaveFileDialog1.FileName, Replace(TextBox1.Text, vbLf, vbNewLine), False, System.Text.Encoding.ASCII)

Visual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?

Jan 7, 2012

I've got the following txt file:

[code]...

Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:

[code]...

Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...

My questions are:

1) How to add the semicolon in the listbox as seperator of the columns

2) How to align the 4 columns in the listbox (as I have an array Item(3) )

Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
