I am already using RegEx to do most of my work now. What would the RegEx expression look like to replace the block above with nothing?

I have an application that uses the following code to write a number of user inputed variables to a text file on a seperate line per variable..What I can figure out despite hours of googling, is how to reverse the process, and load the data from the text file to re-populate the variables.

How to write some value in certain line in ini file??Below is my code..
WritePrivateProfileString("UsefulBih", "MEDIA", "MYRC010,MYRD010,MYRC050,MYRF050,MYRC100,MYRC050,MYRF050,MYRF010,MYRF020,MYRF100", "c:ih.ini")
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.

View 4 RepliesI 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>

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 .
