I am writing a CSV File from a Database. I am stuck in writing lines which become greater then 1024 bytes collectively. It write line terminator after 1024 bytes and thus adds the remaining string to new line which obviously results what I don't want. Is there any way so that I increase the line length limit to some reasonable amount of bytes?

I have a block of HTML which I want to write to a file. It contains about 30 lines and it's difficult to escape all the double-quotes in individual WriteLine statements. In PERL, I can do something like the following to write inline HTML and print everything upto <<OUTFILE to outfile as-is, is that possible in VB .Net 2008?
print <OUTFILE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD><TITLE>GSC Signature</TITLE>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type>
<META name=GENERATOR content="MSHTML 9.00.7930.16406"></HEAD>
<BODY><<OUTFILE
I could save the HTML in a template file and copy it into a new file each time, but that's not very flexible.

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'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))

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

I want to build a macro which adds a ; to every line end, which hasn't already got one and is not empty or a { or }. I use C# in Visual Studio 2010 Professional so I probably need a VB Macro. I need it because I have to migrate Unittest from VBS to C# (Don't ask why). So I got thousands of lines like foo="53" bazz=1337 I do not care if support is dropped, I should be done in some weeks. Also if there is one ; put in to much, i still review the code later.

I'm working on a console application that needs to write a line until a certain value is met and than do the same backwards until another value is met.
The line need to be 51 spaces wide, start and end with the pipe ("|") character and have a cross ("X") character in between.
I can only define both the characters once.
The result needs to be something like this:
|X_________X|
|_X_______X_|
|__X_____X__|
|___X___X___|
|____X_X____|
|_____X_____|
And then from the last line on, go back to form a big X on the screen and start over again, going over and over until a key is pressed.

Is it possible to create a windows application in VB to take form input of a text box and put that to a sharepoint server as new list item?I want an exe that when ran, opens to a form with a text box or two and a submit button, that creates a new list item on a sharepoint list.I am using VS 2005 , code in VB. All my google searches come up with stuff that seems to run on the sharepoint server itself, not a program i hand out to people to run from the desktops.I've tried so many permiations of what i found through google searchs and my brain just hurts atm. I'm new to VB + VS, my background is in VBA on Excel, and i have an solution that works in vba, but causes headaches due to macro security etc.
