Get A Bunch Of Lines From A Text File (they Will Be Filenames Eventually) Which Are Split By New Lines And Puts Each One Into An Array?
Jun 22, 2010
I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

reading a text file into an array after a certain line in the text file, at the moment i am trying to do it using the method below: but i am having trouble thinking about how i can copy everyother line and also how i can count through the array the i = 0 and i = i + 1 are there while "i".
In a line what i would like to do:I need to copy everyother line for a known amount of lines that appears after the line " I FT I KT I " in a text file, but i do not know the position of this first line in the file.

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

I am trying to turn data in a text file seperated by spaces into a 2D array.
It is for a math game. The data is statistics based on the performance of the user. One line looks like this "John Doe 0 0 1 3 0 6 0 22"
I need to put the line into an array and then be able to search by name to display the results. I keep getting extra spaces in the input of the array so the data isnt where it should be. It seems that the first entry works correctly, but appended lines do not enter correctly.
Sub ResultsToFile()
Dim FILE_NAME As String = "C:\Student_Results.txt"
Dim RecordString As String = NameForm.PlayerFirstName & " " &

I need assistance with posting lines from a text file (test scores) into an array. From there, I'll have to average the test scores, find the standard deviation (without using the built in function) and assign grades based on the test scores' deviation. I have already written the code for the user to search and upload a text file. And I should be able to do the standard deviation of the array, if someone can help give me an example of how to send the text file to array and average the lines of the array without using the built in math functions.

As you will see from the code below I need to be able to tell before the array runs how many members of the array there are or else the program will crash. How can I redim the array depending on how many lines are in the text file (RECORDS.txt)

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Is there a way to make an array from all the lines within a file?
For instance, value 1 of array is line 1 of file, etc.
I found a way on Google, but for some reason if a line says something like: http://domain.com/file/file.exe
It will cut off the line to something like: http://domain.com/file/fi

I'm working on a program that when you click a button called new it pops up a new form asking for you to enter a directory location. If the directory exists it saves it into this file:
"C:WindowsSettingsButtonVariableSaves.ini"
I already have working code that saves each directory entered into the ini file on its own line.
Now in this code I'm trying to call each variable back from the ini file when form1_loads and set it to an array called ary() so later I can set the first 10 saved within the array.
So later:
button1.text = ary(1)
button2.text = ary(2)
and so on to
button10.text = ary(10)
and the reason I set the array to record all lines even if theres more than 10 because I want to be able to add more buttons later on.
Here's my current code for saving lines to an array:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FILE_NAME As String = "C:WindowsSettingsButtonVariableSaves.ini"

I want to read each line from a txt file, but instead of using a for, while etc loop i will let the web browser do it (document completed). I want to increment the next line and let the loop continue till its finished.
Just say the data was inside a textbox, i'd do Textbox1.Lines(count) for line one, then i'd do count += 1 and when the web browser has completed, it would start again and repeat the process.
So how do i read the lines from a txt file into an array without looping? And allows me to specify the line number?

I have a Richtextbox with many lines. The data is as follow:
[Z=100, A=10, B=20, C=100]
[Z=100, A=33, B=50, C=255]
I want to split the lines to 3 new Richtextboxes, with the A, B and C values + the line number. Should maybe not be so hard, but I got stuck.
This code extracts the A, but obvious only the first line.
Dim values As String
values = RtbAll.Text
Dim Rawdata As String() = Nothing
Rawdata = values.Split(","c)
Dim s As Integer
For s = 0 To Rawdata.GetUpperBound(0)
RtbRed.Text = (Rawdata(1) & Environment.NewLine)
Next s
