Connecting Up A Sequential Text File To A List View
Mar 13, 2012
What I am trying to do is connect a sequential text file up to a list view. It displays alright but i have a button which is to add certain details to the sequential text file, but instead of adding it in comma separated variable format, i.e. John,Murphy, etc... horizontally it adds the information vertically downwards, i.e. John
had a sequential text file loading into a list box this afternoon, opened the programme a few minutes ago and its not working! The text file was loading first name and surname onto the same line, but now it will only put the first name into it.
Private Sub frmSelection_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim Datafile() As String = IO.File.ReadAllLines("Datafile.txt") Dim query = From line In Datafile
I am trying to create a program for a voters poll, where when a caller calls in, I can enter their vote for one of the four choices in the listbox and it will be automatically added to the vote count. I got that much to work, I need to save the vote to a sequential text file, when a vote is saved. I know I am close but it is just not quite working. I only need help getting the info to save to the sequential text file. I have also included a jpeg of what the form looks like.
I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
Code: "Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008" "Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008" "Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"
I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
i'm trying to load a sequential text file into a listbox, and for some reason it won't move onto the next line? instead i get square characters instead
It appears like:
Where the square characters are, i want it to be an extra line as opposed to just that? here's the
Dim YOUREFILE As String = "C:Documents and SettingsAdministratorMy DocumentsPROJECTFILESYOURSTUDENTSCORES.TXT" Dim objReader As New System.IO.StreamReader(YOUREFILE)
I have a datagrid displaying details from a sequential text file. I need to have a button to search through this textfile and display only that line of data in my datagrid. I am using an input box to enter the persons name they wish to search for. The datafile contains several lines of info like : John, Murphy, 35, etc.
In my program i have a listbox populated with data from a sequential text file. [code] Mary, Murphy, 16, 893782, Douglas etc.From here the user selects the person they wish to see displayed in the datagrid with all all other relevant details from the text file displaying. Problem is I cannot figure out how to refer to the selected person and then get it displaying on its own in the datagrid. [code]

I started working on a product list with an array of products, these products are in a list view. You click the item and it is added to another list view and removed from the one it is curently in. I had it suggested to me and it sounded neater. I had no problems tinkering with codes and getting it opperating properly. But, What I am having trouble with is putting a cost to the product.
The idea is that the user would select products from the list and then they will be totalled together which is why it is important to be able to get the cost in there but not actually visable.Athiest advised me of a method used in combo boxes, because i was originally working with combo boxes. So I tried using that for my needs in a list view. Turns out to be a little more awkward than I thought. I get an error while trieing to add the item to my list box because I havent "declared" it.
I am new to VB and I am trying to add text from a thread to a listview in my Form1.I have tried implementing the invokerequired method but still the new text is not added to my listview.[code]The new text that I add is not displayed in the listview. I do not get any compile or runtime errors but still no new text to list box. I can add text from my Form1 class but not from the thread.
I have been looking ages on Google trying to find a solution. 2 weeks now and I cannot find it anywhere.

I have a list view with a few items in it and I would to allow the user to select the text in the subitems,but not be able to change it. I noticed you can change the items names but not the subitems.Is there a way I can do this in a listview?
I have a BindingList of transactions that I am binding to a DataGridView. The client now wants each row to have a sequential number. (1,2,3, etc).There could be hundreds of transactions. So is there an efficient way to assign a sequential number to each item in the bindingList?I know I could For/Next through and manually assign an incrementing index. But I am concerned about the performance when we process lots of transations.

I am trying to copy the values to another sheet but not in any sequence eg.A1,B2,C4,D7 ........and so on. I am trying this slick way of doing it by the code below ( found on the web) without success so far but I got a feeling I am close to the solution. I am new to any kind of Programming.

I can't find any way of loading all files with e.g (.txt) from a specific directory: C:UsersChristianDocumentsMy Logs I use Visual Basic 2008 .NET, this is how I try to get it:
1. When the form loads it should retrieve the full path and title of the files and then put them in the List View control.
2. When the user marks one file in the list view and then clicks a button the text content should be displayed in a multi line textbox.
I got my code to read a txt file and import it to a list view. (that is on the form2)so on my form i I want to grab the value of listview1 line 1 in form2 so I tried

My teacher as asked me to allow a user to input three pieces of information about a DVD (the ID, the title and the running time) and for the program to add that data to a sequential file. My textbook fails to explain it and I am at a loss as to where my book from last semester is located at the moment.
1. What is a sequential file?
2. How do I display information from it into a messge box?
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
