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 am stuck on an easy problem I'm sure, but for the life of me i cannot figure it out. I need to read a sequential file into a listbox. 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 have a situation where i get a list of directories link for files in a listbox. let say i hav 5 links of diectories of a file in the listbox. how do check each directories for their md5 in the listboxt and have the value of the retrieve md5 in another new list box. i want to create a md5 file checker or scanner. need all the expert help on this cause i have been coding this program a month ago using visual basic 2010 express. i need a list of working code on my failing program...
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 want make a program like a login tool game..in login tool program..i put a button and WebBrowser page..then i want make a my button and WebBrowser read link or target in ini file or inf file...how to make it?
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
[Code]....
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'm trying to make a program that can read .mp3 data (Such as Artist, Album, Year, Track number, etc), but I need to be able to do two things that I have no clue how to do:
1. Read starting from a specified string (E.G, On one line it states: [code]
2. Read until a specified string (E.G, On the previously stated line,I need to read starting from what I said, up until.
webpart vb.bet 2010 not visual webpart I want to grab the selectindexchanged, and run the code after button click. I only really need is the SelectedItem.Text
here's how I did it in VB.net asp page.
Protected Sub listbox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Click_button
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.
I'm using vb 2010 express and composing a program that is using english and hebrew. The problem is the hebrew characters are not showing up in vb when reading the file I stream to. I would like for it to show exactly how I have it written in the text file.
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 have a .dat file in my resource folder that has 1 line in it. I need to read that 1 line into a string so i can use it in my program. Then I need to write another string into a new .dat file into my resource folder.
Im trying to make a game launcher, and I want to have it first see if there are updates. I know this is a really simple problem, but I can't figure it out. This is the code. I want it to read the link.txt and version.txt in the same folder instead of C:/ Oh and make it so it unzips the update into the same folder, and replaces the old files for the new ones.
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?
Currently I'm using this code to read from a txt file, but there is two problem with it.
Dim x As Long = 0 Dim SR As New System.IO.StreamReader("D:A.txt") Dim line As String Do
[code]....
It prints out the content of the txt file twice & I would like to read line by line and store the line in a string.In vb 6.0 I used a socket to create a server & client chat app.Is there some other possibilitys than to use a C4F P2P toolkit for Vb 2008?
