I want to put a function that reads a text file and put it in textbox1. I used this code to read the last line
Textbox1.text = Io.file.readalllines("C:c.txt").last
but I want it to read the third line.
I am reading from a textfile. How can I skip a line if it's empty?
Or is it possible to delete at the beginning of ReadAllLines to remove this empy lines.
An empty line would be following:
text1
text2
"empty line"
text3

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()

This is my code:
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
[Code] .....
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

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.

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?
I 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.

Below is the code in the content place holder. Id like to have this done in the Page_Load or the pre Init.[code]
View 2 RepliesHere'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 want to put all 3 lines in a data grid view.
I have a windows form with a textbox and a button, what I am trying to do is enter a number in the textbox and when clicked on the button to cut and paste the data in to a new text file (from number 0 to the number I entered).ie, textfile 1 has 100 lines of data, I enter 25 and press OK I would like to take the first 25 lines and save them into a new text file and save the remaining lines in textfile 1 so it should be like textfile1 75 lines and textfile2 25 lines.The closest I've come to this is the following but this only deletes the one line..[code]
View 3 RepliesI want to create a little program with textboxes in it, that writes the contents of these textboxes to a file. It also needs to write some predefined lines to the files, even on the same line as where the contents of the textbox is.
Heres an example:
The file should look like this when you open it in notepad:
^1::
Send t Text from TextBox {Enter}
First I think I would need to do this:
Dim ioFile As New StreamWriter("scripting.ahk")
ioFile.WriteLine("^1::")
If I do the above it works.. But how can I write another line where the "Send t" and "{Enter}" gets written automaticly before and after the contents from the Textbox?
I have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:
1) Load the text file lines and split them into a constant and a value
2) Edit the text file lines values
The content of the text file is like this:
[Code]...
This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?

Their is a problem whenever I want to write something to a text file. Please see the attatchement to see what happens when I'm debugging. I've put the code for writing to file right at the end of the program.Here is some of the code which shows how the program writes to and reads from the file:

View 6 RepliesI 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.

View 3 RepliesI 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..

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.
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.

View 3 RepliesI 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 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....
