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.
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 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)
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
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 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. This is my first attempt. (so a chuckle or two is ok after seeing my "difficult" problem)
(This is an excel VBA Prblem) Sub justdoit() Dim s As Variant
Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.
This is my first post in the community. I am putting together a program that serves two functions:1. Takes input from TextBoxes and writes it to a text file.2. Takes the text from the text file and displays two specific strings of text in a MessageBox.This is the code for the button that writes the input to file.

When using .write method the string will be stored at the end of the text file. Is there a method that adds them on top? If not, how can I get this done without using too much memory and processor time?
I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?
I am creating a text file using a save file dialog and copying the path to the text box which file is used to write from vb.net. when i try to write i get an error "The process cannot access the file '....fileName.txt' because it is being used by other program".
The code is below
Public Sub writeInTextFile() Try Dim oWrite As New StreamWriter(TxtOutputPath.Text)
I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code: Dim di As New IO.DirectoryInfo(strPath) Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt") Dim dFiles As IO.FileInfo ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I am writing an application that must generate a plain Text file with fixed sized columns.my current code is:

I want to write a line into a text /.cfg file. the line is = name "ishtiak", i need a space between name & "ishtiak". the text "ishtiak" is loading from a textbox called textbox1. i don't want in the text box my name like this "ishtiak" it will be without "" like this ishtiak but in the text file it will add "" before & after my name.
so the question is: 1.how to add space between name & "ishtiak"? like this = name "ishtiak". 2.My textbox text will be ishtiak,but it will be written like this "ishtiak" [Code]
We have some information that we need to write (about 18KB) to a .txt file stored in one of our network drives. The file is re-written about once every 15 minutes but is read practically at least every second. We are currently using StreamWriter to write file.The file server is in remote location and the round trip ping varies from <1ms to 15ms.
The problem is, sometimes it takes as long as 6 seconds to write the contents to the file, which is definitely way too long even after we take consideration of the network speed. therefore, I am just wondering if there is any efficient way to write the file using VB.Net to improve the performance? Java has a very good tool named BufferedOutputStream, which unfortunately is not available in VB.Net (or I just have not found it).
Application log file have been created to monitor the process and following code has been used to write the log information into text file. For the first time there is no error encountered when the application runs for hours, may be 3 hours i am getting following error "An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" [code]...
I want to write some stats to a text file every time a person loads a page. But every once in awhile I am getting at 'Could Not Open File, Already in use' type of error. I can not 100% replicate this error it is very erratic. My code is
Public Sub WriteStats(ByVal ad_id As Integer) Dim ad_date As String = Now.Year & Now.Month Dim FILENAME As String = Server.MapPath("text/BoxedAds.txt")
[Code]....
how can I lock and unlock the file so I stop getting the erratic errors?
Im working on an assignment for school and i have to write my schedule to a file using input boxes, also i have to use a structured array on the assignment. Both of these i have working fine.I just have one problem, my formatting such like when i write to the file it doesnt look all nice and straight and when i read from the file its uneven also. I know its because the classnames/teachernames are different lengths but i was wondering if anyone could explain to me how to format it to make it look nicer in the text file, and when its displayed on the form in the label

How would a person read a line of a text file by the number of the line. In other words, if I wanted to get the 3rd line of the file, how could I store that third line in a variable. While I'm at it, I might as well also ask how to do the opposite, or write text to a specific line (in this case, writing over the other information on the chosen line).
I have five column in my datagridview. I want to write the contents of datagridview to the text file. let say i enter this values to the gid view
