I'm having a bit of a play with .NET CF 3.5 and I'm going insane trying to figure out how to write a line of text to a file...I've seen the System.IO.StreamWriter function but I dont know if thats what I want, or if its relevant to what I'm trying to do.

i need to code a program to help me in my everyday job, i own my own business and this will help me with my sales. its a very simple program, and i cant figure out how to get my multiple textboxes to write to a new .txt file. i can only get it to do 1 line at a time. I have textboxes. named txtDate, txtCarrier, txtLocation, txtDateEmpty, txtDestination, txtQuote, txtPhone, txtFax, txtEmail.I want the "txtDate" textbox to be autofilled with the current date and time of the user input, which is started on the next textbox.the rest of the textboxes are going to be user input. then when the user is done entering data into the multiple textbox's they would click a button "add" or something to that sort.then those text box entries including the "txtDate" would be written to a new .txt file.in this format, Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email "all on the same line.and when the "add" button is clicked, the multiple textbox fields clear all the data previously entered.and is ready for another user input.
after the 2nd set of user input is entered, and "add" button is pressed,it would add(append) another line to same txt file previously written. example: Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email " "Date2 - Carrier2 - Location2 - DateEmpty2 - Destination2 - Quote2 - Phone2 - Fax2 - Email2 "
then the previously filled text boxes would be empty again, and ready for input 3. and with this you would be able to add countless lines over and over of user input.ok, also when the program launchesI want a msg txt box to pop up and ask. "Where is the Load Origin?" then the user would input data and click enterAnother Msg box would pop up and ask "Where is the Destination?"Next "Pick Up Date" then "Deliver Date" and last would be "Notes" and all that data that was entered into the msg box's will Be at the top of the txt file like a header .

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

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

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.

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.

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.

Basically, I'm creating an application which takes a list of words in .txt format, such like this:
Abc
Def
Ghi
Jkl
mno
What I want to be able to do is modify the words, one by one, so that I end with
Abc1
Def1
Ghi1
Jkl1
mno1
or whatever the user wants.
I created this app in C++ to get the logic, since I am more confident with that

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?

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

I've already used arrays and a random number to generate a sentence with the pattern KLAC, but I need to write this to a text document and then do it again. I have succeeded to write the first sentence, but the second will not register.This represents essentially everything I've tried. (I haven't included the arrays because they're pretty long.)
repeat:
Dim rndNo As New Random()
Dim chosen_aword = aword(rndNo.Next(0, aword.Length))
