Deleting Item From TXT File Based On ListBox Content
Jan 23, 2012I am trying to delete an item from a text file based on if an item appears in a listbox but keep getting an error " Index was out of range. Must be non-negative and less than the size of the collection." The line it is returning the error on is the the first IF statement of the below text.
Code:
Dim Lines As new List(Of String) (IO.File.ReadAllLines("Carl.txt"))
For i As Integer = 0 To Lines.Count -1
If Lines(i).Contains (listBox1.text) Then
Lines.RemoveAt(i)
End If
Next
IO.File.WriteAllLines("carl.txt", Lines.ToArray)
End If
Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)
Apr 28, 2009I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

Oct 14, 2009I want to append a text file with items from a listbox. I tried to search for a code to do that, but couldn't find anything(most likely I don't know what I am looking for). But I wrote this code and got it to work, but after looking at the code, it looks sloppy and I'm sure could have bugs I didn't catch....my question is, is there a better code than the one I made, or will my code work fine.

Save Items In A Listbox To A Text File?
May 27, 2009I've been trying to figure out how to do this correctly for some time now, and I have seen no insight. I'm trying to successfully save all of the items in a listbox without saving items that are not there. What I mean by saving items that are not there is when it saves, it seems that blanks magically appear in the text file.Here is a sample of my current code to save.
[Code]...
I'm not completely sure if it's the loading or the saving that's causing problems, but what would happen is it would add a blank item to the listbox that I do not want.Here's a picture before the listbox is saved, look to the bottom left.Now here is what it looks like after: (notice the red oval)Does any one have any idea what could be wrong?If you want me to attach the text file, just ask.

.net - Deleting Items From A Listview Through The Use Of Checkboxes?
Apr 18, 2012My program takes a checkboxed item and depending on the serial number that is present on the item on the invoice, subtracts one from the amount list I have the following in a listview on a details page which I added with the following code:
Item - Low Socks(pink)
Serial # - 34-75-860
Price - 5.89
Amount - 12
[Code]...
Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2 since there is one item and three subitems to that one item.
