VS 2010 Getting A Button To Read From Xml File Or Listbox?
Nov 29, 2011
I'm trying to get a random line of text to appear in a messagebox upon button click, I want the listbox to be closed while the action is to be performed.
I can do it when the listbox is open but not when closed, here is what happens if I try to do it when it's closed
and the message "InvalidArgument=Value of '0' is not valid for 'SelectedIndex'."
I tried reading it straight from the .xml file the data is stored on, but that didn't go so well either.

I can read the file into the textbox but i want to format the data in the listbox. for example i want to PadLeft(10), delete the excess commas, and give a heading for each column. here is the code i have and attached is the text file.
Imports System.IO
Public Class Form1
Private Sub exitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton.Click

I am making a program, obviously, and I require some assistance. I found an explanation on how to read information from a Text file and have modified it for my needs. Here is my (modded) version:
Public Function GetInfo(ByVal playlistname As String) As String
On Error Resume Next
Dim PlaylistInfo As String
Dim ReadInfo As System.IO.StreamReader = System.IO.File.OpenText(My.Settings.OpenPlaylistName)
PlaylistInfo = ReadInfo.ReadToEnd
[Code] .....
I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.

[code]My program launches, I call the LoadExcludeFolds sub. This should read the contents of the textfile, and if it finds a folder listed in it, in the listbox, it should remove that item.[code]

I figured a fix using if statements which lets me click the button without issues, except just 1; it doesn't read from the listbox. here's the code i'm working with
Private Sub Button5_Click(sender As System.Object, e As System.EventArgs) Handles Button5.Click
Dim a As New Random

I need it to be able to read from the listbox while it is closed, instead it just thinks that nothing is in the listbox, but when the form with the listbox is open, it reads from it perfectly, what shall I do?

I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?

I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub
Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile
But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.

My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.

I created an application that I use when deploying packages which allows users to postpone it from running until they are ready. There are two text boxes that contain restart warning messages.
Is there a way I could use an external file such as an INI where I could place a different message? If the app could read the messages in the text file at runtime and place them in the appropriate text box, it could make this app a little more flexible.
As it is now, if managers want the message changed, I have to change it in the source and recompile. That is not a good way of accomplishing the change.

I'm trying to do is read a text file from a certain line to the end of the file. For example, say the text file is:
Hello
Everyone
My Name
Is Tyler
I would like to be your friend. Would you be mine? I like dogs, cats, and basically any animal. I play the tuba and am in a band at college. I go to UMass. Do u like UMass?
(none of the above info is true FYI)
My code would look like this:
Dim hello as string= io.file.readlines(c:/text.txt)(0)
Dim everyone as string= io.file.readlines(c:/text.txt)(1)
Dim myname as string= io.file.readlines(c:/text.txt)(2)
Dim istyler as string= io.file.readlines(c:/text.txt)(3)
But say I wanted it to read from line 4 to the end of the file? The entire description I would want to save as one variable. How would I do this?
