VS 2010 Reading Raw Text (?) As String To Manipulate?
Feb 29, 2012
I am not sure if this makes sense or not,but I need to process raw text(without any encoding?) that I retrieved from a file recovery application "PhotoRec"
With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.Here is what I am using to process the file:
[code]...
I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "currentbyte".So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

How do you manipulate a text file once you have opened it with Streamreader? I can get the streamreader to open the file and display it in a text/listbox but i cant do things like split and join to it.... It has no effect on the text file when viewed.
This is how i am setting up my string array:
Dim fileName As String = "C: est.txt"
Dim objReader As New System.IO.StreamReader(fileName)
how do I manipulate objReader as a string?

I'm making a program that can read a game music file and able to add some texts after it.So far, this is my code:
For Each foundFile As String In My.Computer.FileSystem.GetFiles("E:O2ChinaMusic", _
FileIO.SearchOption.SearchTopLevelOnly, "*.ojn")
Dim fileName As String = IO.Path.GetFileNameWithoutExtension(foundFile) 'Filename[code]....
My problem is for example, the game music file's title is "Puberty", as you can see, my code is:
StrItm(1) = title & " INPUT TEXT HERE"
but the only one that appear is the word "Puberty" AND NOT "Puberty INPUT TEXT HERE".

still pretty new to programming in general, but I have most of the basics figured out.I stumbled across this problem today, though. I wanted to try making a simple encoder/decoder. However, I am having trouble getting characters from a string.
I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:
For i = 0 To textToConvert.Length - 1
letterList(i) = textToConvert.Chars(i)
Next i
Upon running my program, I get an out of range exception for the middle line above. Am I doing something wrong?

I've been trying to fix this problem for days, but I haven't been able to successfully apply any of the code that I've found to my project the way it is right now. Maybe I'll need to change the way it reads the file altogether.
Anyway, I'm trying to read through a text file line by line, reading each line into its own string.

I am trying to write a code that will byte swipe data in a string.
The conversion should take a 16 characters string, and swipe the first to characters with the last two, then characters three and four with character thirteen and fourteen and so on, in this format if the input string is
A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.
I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like
Dim byte1 As String = Left(MyString, 14)I get an
error saying - Public ReadOnly Property Left As Integer has no parameters and its return type cannot be indexed.

I can write a 1-d string array to file with:
Dim test() As String = {1, 2, 3, 4, 5}
File.WriteAllLines("C:MyFile.txt", test)
but can't see how to write a 2-d array to file.
I've tried this:
Dim test(,) As String = {{1, 2, 3, 4, 5}, {34, 22, 12, 33, 55}}
Dim myfile = File.CreateText("C:MyFile.txt")
Dim row, col As Integer

I'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:
CreateString += TextBox1.Text + TextBox2.Text + TextBox3.Text... (etc)
I have thought about creating a For Next loop which would go something like:
For i As Integer = 0 To intNoTextBoxes
CreateString += TextBox(i).Text
Next
But this really doesn't work. I also found something saying that something similar to this would work:
For i As Integer = 0 To intNoTextBoxes
CreateString += Me.Controls.Item("TextBox" & i.ToString).Text
Next
But that didn't work either.

I have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.

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 trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

I'm having trouble with an infragistics ultragrid using vb.net. I currently have a cell with the value "inner", however I want to be able to display a completely different string for that cell without losing the value. I understand that the cell has two properties, one value property and one text property. The text property is read-only so I cannot simply assign a new string to that.
