What im try'ing to do is when a ListBox item is selected and the value has been given with a NumericUpDown box and the ''Add to orderlist'' button is clicked that it saved it to a file called "orders.txt", not at startup but when the first order is made.
Some requirements:
U can't order the same thing twice ( only edit it within the editor ).
The "orders.txt" has to open on a TextBox1 at Form2 ( the text editor ).
And the user can only change the order amount in the edit program.
Example:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")
so i figured out how to save to different lines in a txt file. and how to open it. it opens fine. every label gets the right value, but when i press a "+" button it should add a 1 to it. e.g: label1 has the value 8 after loading. i press "+" to make it 9. but instead it make label1 to 1. how should i fix that?
here's the [URL]..the code was too long for this forum so i posted the code there.

This is my code: Dim lngLines As String Dim sr As New StreamReader(opdFileAudio.FileName) While Not sr.EndOfStream lngLines = sr.ReadLine If lngLines.Contains("x") Then lngLines = sr.ReadLine [Code] .....
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've been pondering upon my idea on how to create/update a text file using each item in a listbox as lines, but I fail each time. I've searched this forum as well as my friend, Google. Still nothing.
I have a form with a listbox. I'm adding items to the listbox through a file that I saved. When I open the file, I want each line/string in the file to go in as a separate item in the listbox. I've gotten it to work so far but only with 1 string. I need to loop the part where the file is being read to be able to add all the strings that are within the file to the listbox. How do I do this? So far, this is the code I have:
VB .net Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click OpenFileDialog1.Filter =
I am very new to VB.NET, I want to create a Forms Application to load a text file that has lets say 50 lines, some of the lines are identical and those are grouped together and some same format but different make up. Have it loads it into a text box in the form, to see - but I want another button to randomize all the lines and then show that in the box, and then have a Save button to overwrite the orginal.
I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?
I am making a program that requires a textbox to be saved to a file. The problem is that I have made a custom class for a listboxitem, so I can use tags. I need to be able to save the listbox so that it keeps the 2 tags of each item.[code]...
I am currently almost done with my new program which opens, edits, and saves a certain txt file. The only problem I have right now is saving ListBox items to a txt file. If I were to update an existing text file with my program, it would keep the previous data in the txt file and save the data from the ListBox to the txt file.[code]...
I'm wondering how I can save all my listbox items to a file and load them? Each object in the listbox is a custom class and they are loaded into the listbox kinda like this[code]...
Been trying to search the internett and this forum for this commands, but I might have been searcing for the wrong word. Here is the thing.I wanna make a file at the same time as I add it to Listbox.I prefere that the file has the same name as my first label, as there will be 3 more text feelds in that text file.
I wrote this code to save the items of a listbox to a .txt file, and I don't know if I am doing it right. Tp1 is the name of the listbox, and I have this code under a public sub in my module. Here's the
Dim CC As Integer = Form1.TP1.Items.Count Dim C As Integer For C = 0 To CC

I've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.
[Code]...
I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.
Has anyone else come across this where they need to separate Listbox items that are being saved in aXML file.
My Current code stores all list box items into one Long String, I just need know the syntax to separateeach item with maybe, Pipe Delimited or something.[code]...

[code]I have one button to play all the stuff, but it needs the full path to the mp3 file to play, but I only saved the File name to the Listbox.So basically, I'm wondering how to be able to still select files in the Listbox and press Play, when the Listbox's Items do not include the full path to the actual files.I know I could just add the full path to the listbox from the beginning, but I don't think that looks good.So maybe someone can point me in the right direction, or maybe provide me some source code.
I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.
below are a few lines from my text file(10929 lines)I need to read each line and insert into MS Access. each line is a column in my table and the record changes on every 8th line or to be more specific(on every 8th line you will see a number [1,2,3,4,5,6,7,8,9.....] this is where another record starts,
