FileClose(1)

I would like to know how I can read the file line by line and then add all results into an array list.

Reading Text File Line By Line, With Resetting Position To Beginning Of File

Jun 23, 2011

I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.

I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.

I've seen other examples, where it works, but you must open it a different way -- with a file number.

Imports System.IO
Dim I as Integer
Dim LineText as String

VS 2008 Reading Text File Line By Line - Put Into Text Boxes

Sep 21, 2009

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text

Dec 19, 2008

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?

In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:

Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine

[CODE]...

However, I can't find any methods that will allow me to do this.

Comparing Text File Records Line By Line?

May 14, 2009

I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

Search A Text File Line By Line - VB08

Apr 8, 2010

I just joined this forum as I've been looking for a nice and serious VB forum for a long time

I'm having troubles making a program to search a text file line by line for a specific string.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")

[Code]...

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.

now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost

for a "Readnextline" command or something like that?

VS 2008 How To Read Text File Line By Line

Sep 19, 2010

Ok, I saw this code on the net

Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)

[Code]...

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

Parsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?

Feb 7, 2011

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)

In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles txtMassTrackingNo.TextChanged

Append Text To Each Line In An Array?

Jan 1, 2011

Say I've got a variable that contains multiple words, each one separated by a newline. What I'm trying to do is add specific text to the end of each line in that variable.

For example, say the variable contains...

alpha
bravo
charlie
etc
etc.

And say the text I want to append is "newtext"

So then I'd like the output to look like...

alpha newtext
bravo newtext
charlie newtext
etc
etc

What I tried to do is to split that variable into an array (separated by newline), and then use a For Each to append the newtext to each line in the array. But it's obvious I haven't messed around with VB in a long time, as something is wrong with my logic. Here's what I've got...

Dim Text_Array() As String
Dim OriginalText As String
Dim OutputText As String

[Code]....
