Asp.net - StreamReader ReadLine Is Reading Every Other Line?
May 2, 2012
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.
Private Sub btnUpdateRSR_Click(sender As System.Object, e As System.EventArgs) Handles btnUpdateRSR.Click
' Get RSR File
lblStatus.Text = "Getting RSR File"
Application.DoEvents()

Am I being dense here? StreamReader.ReadLine states that: A line is defined as a sequence of characters followed by a line feed (" "), a carriage return (" ") or a carriage return immediately followed by a line feed (" ")

What I have stored in my file is values related to an account. (Just testing, not going to be used commercially). What I need is to draw the values for the username and password, by going through each new line, but .peek() doesn't seem to work for me.
My block looks as such :
public string CheckAccount(string username, string password) {
StreamReader sr;
string filename = "H:\AccountInfo.txt";
string s;
string result = "";
[Code] .....
My code doesn't read from the 2nd line onwards, it just hangs.

I am currently writing a Login Script, and I am having trouble making StreamReader read a specific line in a text file. This is what I have so far (not the entire script, just the reader lines):
Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
Dim file As String = (path + "LogDat.txt")
Dim sr As New IO.StreamReader(file)
Dim line1 As String = sr.ReadLine(1) '' Supposed to read line 1
Dim line4 As String = sr.ReadLine(4) '' Supposed to read line 4
Dim line9 As String = sr.ReadLine(9) '' Supposed to read line 9

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....

Once this reaches the then line a messagebox should display done and clear the program. What I am stuck is the random part and how to display the random line.

Retrieving strings from a serial port with ReadLine works fine as long as the line ends with a linefeed chr$(10).However if no more strings are available to be read, Do Loop or For Next hang up waiting for the linefeed which never occurs.I believe using chr$(0) in place of linefeed would still work with strings ending with a linefeed..Just that the linefeed would be output.I have the complete MSDN Library.

The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.

I'm trying to read through a large text file using StreamReader using the following code
Dim Fs As FileStream = New FileStream(Filename, FileMode.OpenOrCreate, FileAccess.Read, FileShare.Read)
Dim sr As New StreamReader(Fs)
Dim Line As String = ""

The process reads through the file and then exits the loop while only a third of the way through the file.What can I do to ensure it reads the whole file?

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 File As Object

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
