I am doing my IT PROJECT (CV MAKER) at the moment in college and i have little bit problem with reding lines in txtbox.
Dim lines() As String = TextBox4.Text.Split(Environment.NewLine)
Try
lines(0) = " -" & lines(0)
lines(1) = " -" & lines(1)
[code].....
and all of that in one variable?PS. this text box may have up to 15 -20 lines so i need some help for those numbers.
how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.
I have the following code;
Public Sub writetofile()
' 1: Append playername
Using writer As StreamWriter = New StreamWriter("highscores.txt", True)
writer.WriteLine(PlayerName)
[code]......
I am trying to read a specific line from a text file and for some reason when I set my variable loopCounter = 1 To 5 it jumps all the way down to the word "Marty" in my text file but if I just change loopCounter = 0 To 5 it jumps to where it should be which is the letter "M" right after "25". I'm trying to get it to read "25". as this is an assignment for a VB class I'm taking. My text file is at the bottom.
Do While readFile.Peek > -1
For loopCounter = 1 To 5
readFile.ReadLine()
[Code].....
I use this code to read in a text file:
Quote:
Dim fileName As String = fileloc
Using reader As New System.IO.StreamReader(fileName)
While Not reader.ReadLine() Is Nothing
[code]....
THe problem is it reads in every other line.I assume its because its reading line one in the 'while' then the next line being stored during the loop....
when using stream reader to read text files how would i go about reading or referencing specific lines.so if i wanted to read from say line 2, 3, 4 or 10,11,12 in the textfile or what ever.

Dim lngLines As String
Dim sr As New StreamReader(opdFileAudio.FileName)
While Not sr.EndOfStream
lngLines = sr.ReadLine
If lngLines.Contains("x") Then
lngLines = sr.ReadLine

At the moment I want to read all lines in text file to a list box but I don't add strings x, and string y to listbox, and looping in.
lngLines.Contains("y")
I'm writing a program where there are text boxes and the user can enter info and append them to a text file as well as read from the text file and view the various entries in it. The problems I'm running into are that I have a button that opens an open file dialog box allowing you to select the file, and I want to get it to open the first entry of that file in the correct text boxes. the code so far looks like this
code:
I used to have this bit of code in there but there was a conflict with the .txt file being used more than once at the same time while it was in there.

Im also having trouble writing to the file and I'm not sure why. I have an "Append" button that has this code in it

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.

Does anyone know how to read individual lines off of a text file?
If the textfile looks like this:
Text1
Text2
Text3
Text4
You could make it so on timer1 it sends text1, then on the next tick text2, and so on?
It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on.(I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()
[code].....
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array.
I'm trying to read lines from a file and split them into two words contained in a two dimensional array.[code]Does anyone know why I'm getting this error?
View 1 RepliesI am working on an app now, and I need it to read text from a .txt file, but there's more. Here's what I want it to do:
Dim text as string
Find "file.txt"
text = line1 in txt file
Do something
text = line2 in txt file
Do something
text = line3 in txt file
Do something
And so on, until there are no more lines to read. I have searched, but all that I have found requires you to preprogram the amount of lines in the .txt file. I want to be able to add lines later without having to go into the code and add more.
I am new to ASP.Net and am trying to set up some content pages to work with my master page.I currently have the following text hardcoded into an asp:contentplaceholder and it works just fine.

View 2 RepliesI want to put a function that reads a text file and put it in textbox1. I used this code to read the last line

Here's what i've got so far, i've written all of the data that i'm going to put into my config file, however i'm having trouble reading the specific string values that I need from that ini file. The parts of the ini lines I want to get are the values in between the I've tried using streamreader a couple things but i'm having trouble figuring that out. I need to parse each line of the ini file to get that value in between the single quotations, so that I can set the value for my richtextbox background and text color as well as a few other things that i've set up in my notepad including tab spacing and so on. lots of these different values need to be converted from a string value to integers, and boolean values as well. (4 of them, the rest of them don't have to be changed because they are already string values when my application reads them to determine it's application load settings.
EDIT: I just noticed in the preview that this is from the version of the app where I had streamwriter write "______ value=" & Something to a file. lol some of the (')s are still in this version, so please excuse that little part. I had them in, but took them out so that I could trim data to get a value easier, but I want to use (')s hopefully when all is said and done.For example, just to restate what I want - in the ini file it will read [setting name] value='VALUE'I want to be able to "get" the string value of "VALUE" within the ini file between the 2 single quotations '

I'm trying to create a program that stores a users stats for their character (for something like an RPG). I know how to write more than one line in a text file, but I want to learn how to read and write text on specific lines of my file. I know that you can just read each new line individually in order using a StreamReader, such as
username.text = readLine.ReadLine()
userage.text = readline.ReadLine()
[Code]....
This is good for just displaying the stats and changing them from a constant interface, but I'm afraid that eventually I'll need to read/write specific lines, like reading the fourth line which might specify magic level, or writing a new money amount.
I am in the process (slow process) if learning vb.net by trying to create a simple application that will read and write (save) chosen information to a text file. The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.[code]When I start debugging mode it does not display the text until I click onto the text box and it's displaying the first line of text in the file. How do I skip the first line of text and have it display the second line (or the 6th, 24, or whatever line I need to be displayed)?Then I can start working on learning to use streamwriter

I am trying to create a For Each Loop in my program.
I have 20 lines worth of data in my RichTextBox, and I want to apply a ruleset as follows:
If Textbox1.Text.Contains(Printer(13))
Then ClassifyTextbox.Text = "Printer - Jam"
ElseIf Textbox1.Text.Contains(Printer(9)) Then ClassifyTextBox.Text = "Printer - Toner"
ElseIf Textbox1.Text.Contains(Printer(i)) Then ClassifyTextBox.Text = "Printer"
The 20 lines I have are IT related issues, e.g 'The printer has a paper jam' The Classify Textbox displays the class the issue relates to, then I have some code to send it to a text file for storage.
Each of the 20 lines are different classes, For Each Loop statement to read the first issue classify it send it, then repeat 20 times, so that my text file has 20 rows of data, but each issue has been classified due to my ruleset in the code above?
