VS 2008 StreamReader Reading Certain Lines From Text File

Aug 15, 2010

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

Reading/Writing Specific Lines Of A Text File?

Apr 21, 2009

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.

Delete Lines From A Csv Using Streamreader Or Streamwriter?

Aug 14, 2010

I am writing a click event to delete an item selected from a list view which will utlimately be deleted from the csv file the information is coming from.Currently I am having streamreader read each line and then replace the selected line with a blank line. This creates blank lines in my csv files. Is there a way to delete a line using sr or sw without creating blank lines?Or is there a way to have them read/write a file skipping any empty lines?

Using StreamReader To Read Lines From Textbox?

Dim file as system.IO.StreamReader

Listbox And Streamreader - Select More Than One And Have The Whole Of The Lines Loaded?

Using Visual Studio 2008

I have a Listbox where i use OFD to list selected text filenames, can be multiple and from different drives

I would like to be able to select more than one and have the whole of the lines loaded. I have tried many approaches, 'For each line' for example, but cant get my head around it. Another issue is that i would only like to see the textfile name in the listview box instead of path and filename.

Asp.net - StreamReader ReadLine Is Reading Every Other Line?

I am looping through a text file and reading and then parsing each line.. then, inserting into a sql server. The problem is, I am getting every other line. Any thoughts? I read another post on here that is similar and it says that that person was calling the ReadLine twice... which makes sense. I just cannot spot where it is happening.

Why Is Streamreader Not Reading Entire File

Jul 2, 2010

I'm having an issue with the streamreader. I had it working but I've changed something and it has stopped.

I have it in a Do While loop reading line by line, but it doesn't finish reading. It reads about 27 lines out of 4000, then stops.

I changed the contents of the file it was reading, but it's still just save as a txt notepad file.

I also changed how I tell it which file to open (UserSelection.T2) however it does open the file just doesn't finish reading it.

Doesn't kick back any errors, it just doesn't read the entire file.

Dim FSO As Object
Dim File As Object
FSO = CreateObject("Scripting.FileSystemObject")

Streamreader Limits - The Streamreader Works Fine Until The File Is More Than 100,000 Bytes Long?

Apr 19, 2011

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

StreamReader/Writer - Loads An Entire Text File Into A Streamreader Variable

Jul 9, 2009

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.

There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.

Display Specific Lines From A .rtf?

Oct 2, 2011

At the moment I'm using:

For Each book In books
result.Add(File.ReadAllText(book).Substring(0, 500))
Next
Return result

to display the first 500 characters of an rtf file I'm drawing from in earlier code, but I'm now wanting to specify line - for example lines 4 - 20.I can't find any way to get this to work as when I change the above code to:

For Each book In books
result.Add(File.ReadLines(book).Substring(4, 24))
Next
Return result

I get massive issues stating "Substring is not a member of 'System.Collections.Generic.IEnumberable(Of String)" I feel like I'm literally 1 line of code away from this being fixed but cannot get my head around it.
