I made a post earlier, but it seems to have been deleted or moved?
i pmed ComSec he said my question was within forum regulations, so not to sure why it was moved or deleted
I am looking for, a way to replace all instances of "String1" with "AlteredString1" in a text file "List.txt"
"String1" should show up in List.txt 2 times, so i am looking for outside code that can do this, i have used google over the last 2 days, and i did find one example code that did exactly this
i thought i had added it to my favorites so i could go back and look at it, but when i came back the next morning it was not in my favorites.
ive been looking and trying differnt search strings in google but i cant seem to find that code again.
Thank you in Advance

You'd have to use the streamreader and streamwriter classes. Don't have my Visual Studio installed at the moment so I can't make an example now, but you can find all the info you need here:
Streamreader:

Streamwriter:

Good luck!
edit: maybe if I have the time I'll have a look at it tomorrow fellow 'MW-dude'

Here are my 2 favorites options:
1. Open Notepad, use the search, replace function.
2. Learn the power of regular expression, that can be easily done in perl

hope it help, your post was not really clear to me.
i'll try and explain a bit better, i am already using the SreamReader and StreamWriter to read from files and write to other files
heres a clearer representation of my situation,

so as you can see, i have 2 files, one file has the before string, and the second file has the after string
i am already using the StreamReader and StreamWriter to read the first string file, then im using the Streamwriter to write out the new file with the new altered names
i want to go into the MasterFile.txt and find all instances of the first string in String1.txt and repalce it with the first string in NewStrings.txt, and find the 2nd string in String1.txt and replace it wiht the second string in NewStrings.txt
and i want to keep doing this until i run out of strings in String1.txt or NewStrings.txt, but either or, since they should contain the same number of lines(strings)
hmm..Here is the solution.
Write this statement on top on your project.
Imports Microsoft.VisualBasic
Use the Stream Reader class and read the text file to a string variable.
The use the Replace Function and voila...
Example.
YourString=Replace(YourString,"text to search for","Text to replace with",1)
'Where YourString is the variable the has the contents of the text file.

VN.net can't replace entire strings. (ore it just didn't work for me)
| CODE |
| Private Sub makenormallistIPlist() txtInputIPlist.Text = "" Dim dTelip As Double Dim stext As String Dim sFile As String For Each sFile In ofdIPlist.FileNames Dim slijn As String FileOpen(1, sFile, OpenMode.Input) Do Until EOF(1) slijn = LineInput(1) if slijn = "string 1" then stext = stext & "altered text" & vbCrLf else : stext = stext & slijn & vbCrLf end if Loop FileClose(1) Next txtInputIPlist.Text = txtInputIPlist.Text & stext End Sub |
that replaces strings from a file and outputs it to a txtbox.
the code might notw work, i just ripped it out a x-scan parser i made. but it should give you a good example
i forgot, you need to import "Imports System.IO"
ok thx final beta, will try that out soon, need to work out a previous flaw first,
