VS 2008 Find And Replace A String Within A Text File?

Dec 25, 2011

I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.

Open A Large Text File / Find And Replace A String

Nov 1, 2009

I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

Search For A Formatted String In A Text File?

Sep 21, 2009

The format I need is a group of numbers in a text file and it looks like this and it will always look like this:xxxx x xxxxxxxx xxxxxxxxx x xxxxxxxxxxx xxxx x

The problem is that it can be anywhere in a text file so I cannot search by a particular line.

How can I search for this type of string format in a text file?

Search Text File To See If String Is Present

Apr 10, 2012

So I am trying to create a Win App to make copying files using Robocopy easier and eventually other tasks. Basically what I have so far is a Button that calls the Sub Robcopy_EXE. There is a tab on the form with 100 check boxes, one for each terminal, that will be designated by the user and a check box to determine if you want a detailed report or not from Robocopy. I also have a text box for the user to input the first 3 octets of the site IP Address. The check boxes and Input field are used to create string "Terminal_input" which is what runs Robocopy in CMD. Robocopy logs its progress to a text file that I have labeled "Status.txt". That is as far as I have gotten.

Read Text File / Search For String Then Add To Line And Write Back?

Nov 18, 2010

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.

Search And Replace A Very Large File

Dec 6, 2010

I have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?

My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.

Replace A String Twice With OldValues Having Same Text Within?

Apr 26, 2010

I am trying to take a block of text and scan it for specific text (name) and turn it into a URL, specifically:

Block of text:

Chairman Joe Smith has announced a new plan to decrease expenditures by outsourcing the planning of the new dining hall. Smith states the current project managers do not have excess time to commit to this new project and this will be less costly than hiring a new or contract project manager.

Now what I am trying to do is take any instances of Chairman Joe Smith, or Joe Smith, or Smith, or Chairman Smith and put that in a link to his profile/bio. Using any string methods that I know of (string replace, string builder, add text to before and after a matching string) I would run into the problem when scanning for Smith and then any of the other names.[code]...

Why Can't Do String.Replace() On A IO.File.ReadAllText() String

Jul 11, 2009

I am using System.IO.FIle.ReadAllText() to get the contents of some template files that I created for email content. Then I want to do a Replace on certain tokens within the files so I can add dynamic content to the template.Here is the code I have, it seems to me like it should work just fine...

Dim confirmUrl As String = Request.ApplicationPath & "?v=" & reg.AuthKey
Dim text As String = IO.File.ReadAllText( _
ConfigurationManager.AppSettings("sign_up_confirm_email_text").Replace("~", _

[code].....

For some reason I cannot get the %%LINK%% and %%NAME%% Replace() calls to work properly. I checked to see if it was encoding-related, so I made each file UTF-8. And also used the forced encoding overload of ReadAllText(String, Encoding) and still no dice.
