Reading Text File Into Listbox - Each Line Of The Textfile Is Placed On The Listbox?
Feb 12, 2012
I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file"
Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?

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")

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)

I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click
Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio

If lngLines.Contains("x") Then
lngLines = sr.ReadLine

At the moment I want to read all lines in text file to a list box but I don't add strings x, and string y to listbox, and looping in.
lngLines.Contains("y")

I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.

I've setup a TextWriterTraceListener which outputs the debug messages I've written to a file.This works fine however what I am trying to do know is output the content of this file to a textbox using a streamreader object.I originaly thought it may because I did not set the text file to allow read/write access so I changed this by setting the following:[code]

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

I'm trying to read multiple values from a registry subkey in the CurrentUser key. I need to display these values in a listbox with multiple lines. I so far can only get one of the values from the subkey. I know (or at least I think I know) that I need to list the values in a string (with a possible loop), and then just display the string to the listbox. The subkey is the TypedURLs under CurrentUserSoftwareMicrosoftInternet Explorer Typed URLs. Here is my code I have so far (I did a year of basic VB as part of my Uni course).[code]

Basically, I'm creating an application which takes a list of words in .txt format, such like this:
Abc

What I want to be able to do is modify the words, one by one, so that I end with
Abc1
Def1
Ghi1
Jkl1
mno1
or whatever the user wants.
I created this app in C++ to get the logic, since I am more confident with that

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

I am reading a txt file and displaying the contents into a listbox but it generates an empty listbox item at the bottom of the listbox. I am splitting the textfile each time it finds a new line in the txt file;
.Split(vbNewLine)
The problem there is always a blank line in the txt file at the end and so generates a blank list item. How can I remove this blank list item from the listbox? Is it best to try to remove the blank line from the txt file first or the empty list item from the listbox after the file has been read?
