I have created an XML file using streamWriter.. Now, i want to remove the line breaks in my XML file.. Is there a way to accomplish this task.
[Code]...
I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

I've been trying to fix this problem for days, but I haven't been able to successfully apply any of the code that I've found to my project the way it is right now. Maybe I'll need to change the way it reads the file altogether.
Anyway, I'm trying to read through a text file line by line, reading each line into its own string.
I'm trying to build an app that would search a text file for a string entered by the user, and delete the line of text containing that string. Here's the code I have. The code works, but since I'm relatively new to VB and programming as a whole, I was wondering if there's a better method out there. he strFilePath is handled by the openfilediaglog
Dim strSearch As String = Replace(MaskedTextBox1.Text, "-", "")
Dim strLine As String = Nothing
Dim strAllText As String = Nothing
