StreamReader/Writer - Loads An Entire Text File Into A Streamreader Variable
Jul 9, 2009I'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.

Streamreader Limits - The Streamreader Works Fine Until The File Is More Than 100,000 Bytes Long?
Apr 19, 2011I 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?

Feb 15, 2012I am making a simple application that will be able to store competition data into a text file that I have given a custom extension to on saving. Here is an example of the format that i have saved the data in.
Code:

[Type]Teams[Type]

When i open the file, i want to redisplay the data in separate text boxes. Later on in the project i want to be able to search within the file for headings for example;
if "[Heat1]" is present then get all text between [Heat1] and [Heat1]
i am currently able to use the streamreader and open file dialog to retrieve the entire string of text fromthe however i am not sure how to go about getting the text between the headings I have used.
StreamReader / Writer To / From A Text File?
Sep 28, 2010I've Googled this for a long time but I haven't come across an answer...or I didn't realize it if i did. I need to create an advanced clipboard that will allow you to save 50 phrases for later use. It will have 5 tabs, 10 phrases on each tab with a button next to each phrase to copy. So, the user will open the program; click the appropriate tab then click the button next to a phrase to copy it to the computer's clipboard so they can paste it somewhere else.

Looping Through A Text File Using StreamReader Causes A "Cannot Access A Disposed Object."
Feb 15, 2012I have the following basic code to read a text file from a StreamReader:
Using sr As New StreamReader(FileData)
Dim line As String = String.Empty
Do
'Error occurs on the next line after looping
'past the *last* line in the file...sometimes
line = sr.ReadLine()
'Some code here to parse and process the line
Loop Until (line Is Nothing) OrElse (line = String.Empty)
End Using
I tried changing the Do Loop to Do While Not sr.EndOfStream I tried checking If sr.ReadLine IsNot Nothing and a few other things but I keep getting the Cannot access a disposed object. Object name: 'SslStream' error after all 105 lines have successfully been read and processed. This code has been working for a couple of years, but there seems to be some issue with certain files (recently) that is causing this problem.
I opened the file and I didn't see anything out of the ordinary. No extra blank lines, funny characters or anything of the like. Just a normal file with 105 properly formatted lines. So even know there is something about this file causing the error, I need to obviosly handle this programatically.
What can I do to prevent the sr.ReadLine() line of code from throwing that exception that I have not yet tried?UPDATE Upon reading the last line of the file, the 'EndOfStream' property on the StreamReader goes immdeatly to: EndOfStream: {"Cannot access a disposed object.Object name: 'SslStream'."} It never toggles to 'True'. This makes checking for this condition problematic.
I think I have figured out why this issue only occurs sometimes: if I add in a blank line to the file at the end, none of this ever occurs. It is only when the last line of the file contains data. Still, I should be able to handle this programatically. Telling the vendor supplying the file to always add a blank line at the end should not be the solution.
