I am making a program for work, i have it partly coded, unfortunately i don't have a wifi connection for my laptop right now which makes it hard to add my code here. What i am trying to do is have the user pull in a text file from anywhere on the computer using a open file box that pops up, i got that part, to make sure that is working i have a textbox that reads the data of that text file, it gets pulled in fine using a stream reader. Now what i need to do is search the text file for certain values, and depending on the selected item in the listbox which is on another form, change that value in the text file, im guessing i will need to use a stream writer, and ive seen examples used based on the file location(C:....) but in my case im not sure how to do it.

Hex(D1) is my column Terminator and need to replace it with ",".
I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:
Code:
Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click

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.

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.

My original example could be solved using other methods. This example is more representative of the actual problem:

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

I have a richtextbox in a form that opens a text file line by line.
Each line contains texts that is to be imported elsewhere and is delimited by commas.
The first two fields are dates and are fine. The remaining fields are all text and need quotations inserting.

How can I replace character/word in text (loaded to richboxtext) but only for those which are not on the "block" list ?
Dim str As String = RichTextBox2.Text
RichTextBox3.Text = str.Replace("1"c, "A"c)
But I want add list of words which should be excluded. I thought that I can do something like :
Dim str As String = RichTextBox2.Text
If Regex.IsMatch(RichTextBox2.Text, "shows") Then
Else
RichTextBox3.Text = str.Replace("%"c, " "c)
End If
RichTextBox3.Text = str.Replace("1"c, "A"c)
Dim str2 As String = RichTextBox3.Text
RichTextBox3.Text = str2.Replace("2"c, "B"c)
But it's not working as it will just skip replace of % for whole text and I want just just exclude particular word from list from being replaced...

I am trying to open up a text file that contains some text. I have 3 text boxes on my screen. What I need to figure out is how to replace multiple words (1 in each textbox) with text it finds in the txt file.
I can do this by using the single find / replace feature but I'm trying to be able to fill out the 3 textboxes and then click my find / replace button to have my Regex find each predefined word and replace it with what is in the text boxes.
Here is my code to get the find / replace one word at time feature. I've tinkered with this to just add more variables to my Regex but it doesn't seem to work.

First it might sound like an ordinary task but keep reading it isn't. I can't figure out how to find a phrase in a text file, and replace it with something else. Tried lots of things but always ending up with empty hands.
Suppose there's a text file in this order:
valueabc=6000.0000
valuettt=200.0000
valuexyz=7000.0000
I want to;
1) Find the phrase (e.g. valueabc) by scanning the whole text,
2) Replace the number that starts after "=" and ends before ".", namely "6000" in the middle with any number value i want.
I don't need the parts before "=" and after ".", only the number in the middle.

I need to develop a small application which can do a batch find and replace on all xml files within a folder. Example:
<cardHolderName>
<firstName>Geraldine</firstName>
<middleName>
[Code].....
I want to replace ALL <firstName) tags to John and all <lastName> tags to Smith to protect sensitive date. In addition, there will be other tags such as address, ss number and phoneNumber.
NOTE: There may be multiple instances of <firstName> within the file. 1000 xml files with all replacing names, address etc. with the same fixed name such as John Smith These will be used for testing and to prevent sensitive data from being leaked
There is no doubt that I can do this the long and dirty way. (I am working on).
