View 4 RepliesHow can I remove lines from a text file at the index of a listbox's selectedindex?
View 4 RepliesI have a serious problem, I have 3 listboxes, and all three of them will get items that contain no text. My problem is that I have the same code for all three listboxes to remove "" from the listboxes except one listbox will not remove the items. I've tried countless times to remove the empty items and failed. So how do you see if a listbox's item contains no text?

OK, straight to the point.I write folder names to a file like this :
Code:
Private Sub WriteExcludeFolders()
Dim SelFolders(clbExclude.CheckedItems.Count - 1) As String
Dim i As Integer
[Code]...
[code]My program launches, I call the LoadExcludeFolds sub. This should read the contents of the textfile, and if it finds a folder listed in it, in the listbox, it should remove that item.[code]
View 7 RepliesAll I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

i have a listview box full of items, image below:
when i click a button i would like a msgbox to pop up displaying how many are alive.
How would i do this ?
Also how would i remove all items that status is "Dead"
Imports System.Collections.GenericI
mports System.Net
Imports System.IO
Public Class Form2
'Dim filename As String
Public ftpSettings As FtpClient
[Code]...
I don't know what's wrong, i can only move the 1st item but the second and so on doesn't make any changes. It remains in a listbox.
So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I want to write directly to the source file. The files I want to edit are only about 30KB
I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
Dim values As New Dictionary(Of String, Integer)()

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.
