Max File Size For File.ReadAllLines?

Mar 31, 2010

I need to read and process a text file. My processing would be easier if I could use the File.ReadAllLines method but I'm not sure what is the maximum size of the file that could be read with this method without reading by chunks. I understand that the file size depends on the computer memory. But are still there any recommendations for an average machine?

Pick Random Word From .txt File And Display In TextBox (VB Express 2010)

Jan 15, 2012

I need to have two pieces of software, made in vb where one encrypts the contents of a .txt file, and the other decrypts it, and then picks one word at random and displays it each time a button is pressed, but never displays the same word. Or, if there was a way to hard code it into the program as there is only 5 words that would be better.

Pull A Random Word From A Text File And Check Against User Input?

Apr 19, 2011

I need to pull a random word from a text file in my resource folder (visual Studio 2010) and then have a user enter a letter to see if it is in the word. Yes, Hangman game. There is more, but right now I need to pull from that text file for a start. I know what I have is not even close to right under "Get Word Button", but I'm kind of confused about the process.

Public Class hangMan
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim word As New Random
End Sub

IO.File.ReadAllLines ANSI Characters (ASCII > 127)?

Feb 14, 2012

I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. " (Ascii 196), (Ascii 246) and (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem. OBS: This is already solved, found the answer by myself:

Dim myEncoding As Encoding = System.Text.Encoding.GetEncoding(1252) ' Windows-1252
Dim strLibrary As String() = IO.File.ReadAllLines(FileName, myEncoding)
Problem was to find right character set, which was Windows-1251 (ISO-8859-1)

Use ReadAllLines Method To Read A File And Print A Line Containing A Particular String?

Jun 29, 2010

I have a text file (CSV) approx 100k lines (8Mb). I want to search the entire file for a particular string eg, "apple" and for all lines containing the string to be printed in a text box. have successfully done this using streamReader to parse the CSV and check each element against the search word eg. apple. This has proven to be very very slow and I have read that the "ReadAllLines" method is much faster.

File I/O And Registry :: Random Access File Larger Than Text File?

Jan 7, 2009

For reference the first 16 digits of Pi are:

File Access - When Open The File With Something Like Notepad, It Shows Random Ascii Chars?

Oct 19, 2011

Years ago when coding with VB6 and earlier, I used a file open command to create, read, and write a file that made it easy to store useful information.I believe it was binary and you wrote/read the data to a specific line in the file. When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

File I/O And Registry :: Random File IO In VB 2008?

Feb 28, 2012

I have managed to learn a little of VB 2008 but I'm still struggling. I managed to convert one VB6 program to VB .net but all the file IO in it is sequential access.I'm trying to convert a VB6 program to .net. This program uses almost entirely random file IO.In one of the books I have, I found an example which, with a minor mod worked. I tried using that code to modify my program and it does not work. In my code, the FileGet results in the obj containing null strings. Yet in the sample program using the same structure, the obj contains actual data.The file is being opened because the record count is calculated correctly [iUpper = LOF(F_Trk) / TrkLen].

I used a Type in VB6 which I converted to a Structure in VB 2008. The function in which the problem occurs is below as well as the Structure declaration and the Function it calls (PAB) which is a derivation of the PathAddBackslash API call.Is there an easier, more efficient way to achieve the same results in VB .NET?[code].....[code]......

VS 2008 Add The Word To A Text File And Create A Folder With The Word As Its Name?

Apr 25, 2009

The following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.

1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.

2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.

However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?

Imports System.IO
Public Class Form1
Dim pathlist As String = "M:Visual Studio 2008ProjectsEnvironment and Conservation GlossaryEnvironment and Conservation GlossaryGlossary List.txt"

Label To Display A Word For 5 Seconds And Then Move Down The List In A Text File And Display The Next Word?

I have a label that is supposed to display a word for 5 seconds and then move down the list in a text file and display the next word.I'm oddly able to make it work in random mode, but not going down the list in order.. random would be ok if used words didn't come up again.

Code:
Dim DurHold As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath & "FlashWords.txt")
Dim DurDelimiters() As String = {vbNewLine}
Dim DurTextLines() As String = DurHold.Split(DurDelimiters, StringSplitOptions.RemoveEmptyEntries)

Create A XML File With A Random Name?

I have some really sloppy code that creates an XML file with a random name. The random name (SessionID) is passed into the Sub, but the sub checks IF File.Exists first. If it does exist, it creates a new randoms file name based on System.Random (has to be done this way because it is also a SessionID).

How To Add To An Existing Random File

Jan 19, 2010

Im creating a login system that allows staff to clock in using a 5 digit code. Staff members can also use the "add an employee" function to add a new employee to the Random File.The problem is, everytime i try to create a new employee and hit the save button, the new record writes over the existing records, one by one, everytime the programme is stopped and started up again.

My Question is: How can i get the new record to be saved, without deleting existing records,

Here is the save buttons click method:FileOpen(fileNumber, "C:employee.dat", OpenMode.Random, OpenAccess.Write) 'open the file with Write Access
myEmployee.name = txtNewName.Text 'adds the name
myEmployee.id = txtNewID.Text 'adds the ID
FilePut(fileNumber, myEmployee, n) 'save to the file
FileClose(fileNumber)
