I am reading a file from the default location. I request a file by name only using an InputBox. If the User types a file that does not exist I get an exception error. I want to be able to handle the problem by outputting to a list box that the file was not found. My Code is something like:
sr = IO.File.OpenText(fileName)
IF fileName <> "found"
Handle issue
Else
Continue Code
I want to run a check to make sure the file does exist in the default location but not sure how to get it done. I had seen the Public Shared Function FileExists but I am not quite sure how to make it work.
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?

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.

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()

The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

Could not find file 'c:usersandrew l millspaughdocumentsvisual studio 2010ProjectsAJoperatingsystemv1.0AJoperatingsystemv1.0inDebug

It points to Application
Does anyone know the reason as to why I get this message when I run my program?

I was able to code a sub that opens a StreamReader and Writer. The Reader reads a *.txt file and the Writer modifies it line by line as it's entered into the memory then writes it to a temporary file which is then copied over the file that the Reader read.
The problem is that the StreamReader and Writer seem to fail to close.At first when I tested it I would get an error stating:
Object reference not set to an instance of an object
I put breakpoints in the sub to figure out where it's erroring out and it's erroring out when it does sr.close() and sw.close() (Reader/Writer.close())Here's the code for the sub. Maybe someone can tell me what I did wrong.

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.
I have a fairly straight forward peice of code that just tries to set the default saved directory for a standard .net save dialogue to a specific folder. If that folder doesn't exist, it sets it to the desktop. This works fine for everyone but one user who is getting the following error: Could not find special directory 'Desktop' How is that even possible?

I'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.

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.
