Sort A Simple Text File Starting With The First Character And So On
Sep 21, 2009
I have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?

I recently made a simple pseudo-encryption program that changes each character into another. It is capable of encrypting and decrypting a string. This can also be done to any text file as well. The characters range from ASCII 32-254 (This on it's own may be an issue because of #127 being DEL).
Because I believed my own coding may be at fault, I attempted this with Triple Des with identical results.For Triple Des, the requirements for en/decryption was:
Encrypt: String to Byte
Decrypt: Byte to String
And to change them either direction, I used UTF8. I also attempted ASCII and UTF32, but I don't know what I should do. I am considering dropping this but I want to learn problems like this because I am currently in college and haven't started my core classes for programming yet and want the head start.
The point where I have come into a problem is attempting to do this to another file type like an image. I looked at the results from encrypting then decrypting and the results were similar, but it seems file encoding must be the culprit.

How would you select the last part of a string starting at a specific character count. For example I would like to get all text after the 3rd comma. but I get an error saying "StartIndex cannot be less than zero."
Dim testString As String = "part, description, order, get this text, and this text"
Dim result As String = ""
result = testString.Substring(testString.IndexOf(",", 0, 3))

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.
Private Sub RadioButton_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton.CheckedChanged
Dim fileReader As System.IO.StreamReader
Dim lineRead As String
If RadioButton.Checked Then

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

i am trying to create a program which will get data from the .txt file. I got to stage where program gets me the information from the .txt but i would like it to be sorted.
Here is sample of text in .txt
01:13:11 Setting up 01:13:11 Loading level 01:13:12 Now accepting input on 25565 01:13:13 Level saved! Load: 0/16
I want it to take a new line after the time so it would look like this.
01:13:11 Setting up
01:13:11 Loading level
01:13:12 Now accepting input on 25565
01:13:13 Level saved! Load: 0/16
The code in visual basic that i use now for inputing the text file.
Dim FILE_NAME As String = "C:Documents and SettingsAdministratorDesktopmcserver.TXT"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
TextBox2.Text = objReader.ReadToEnd
objReader.Close()
Why do i need it ? This is a log from command promt, this app will be for a game server.

Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....

I have a dbase.txt file with some data in it. i.e -
Institution Course StudentID
XZY ABC 2010-1111111 "the spaces between columns is one tab space"
XYZ ABC 2010-1222222
XYZ ABC 2010-1333333
I want to perform simple SQL like operation - i.e -
SELECT * FROM dbase.txt or
SELECT Institution FROM dbase.txt WHERE StudentID=2010-1111111 and an insert operation like -
INSERT dbase.txt VALUES (XYZ ABC 2010-1444444)
I have written some code which is not even closer to what I mentioned above. My program can read only the whole text file. There is a menu, but not functioning well, as well as my write function which is not working at all.
Below is my code -
Imports System.IO
Module Module1
Sub Main()
Dim intInput As Integer
Console.WriteLine("Main Menu")

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...
[4188]
LongName=
ShortName=
LauncherDirKey=

Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.
