View 5 RepliesListbox 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.

Directory Items TO Listbox Items?
Mar 17, 2009I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".
UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).

VS 2005 Check Grid Items If Checked ListBox Items Checked?
Aug 21, 2009Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

Loop Through All Selected ListView Items
Oct 7, 2011I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.
For i As Integer = 0 To ListView1.Items.Count - 1
Dim ftp As New FTPclient(host.Text, username.Text, password.Text)
ftp.FtpDelete(ListView1.SelectedItems(i).Text)
Next
Some info:
The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.

VS 2005 Erasing Items In A Collection Using A Loop?
Jul 1, 2009I often use a for/next loop to cycle through a collection to find a particular member of that collection based on some criteria. This works fine in every case except one: when I want to then erase the very member of the collection I just found. For example, if I wanted to give the heave-ho to every obect in a collection class that has a member veriable Color equal to Red:
[Code]...
The problem is once the collection class member is erased it makes to loop invalid because taking out the member reduces the total count of the collection in the middle of the loop. Eventually I get a "Index is out of range" error.This circumstance has bothered me every so often; I bet more experienced programmers have a different type of loop system that works better than this when you want to erase a collection member.
