VS 2008 - Loop Inside ListView And Its Columns Sub Items
Apr 22, 2011
I need to loop inside listview and its columns Sub Items. I'm currently using this.
For Each item As ListViewItem In ListView1.Items
For Each si As ListViewItem.ListViewSubItem In item.SubItems
Next
Next
But it over loops on the items causing the code to produce incorrect tasks.

I'm gathering a list of files within a directory and then adding them to a ListView:
VB.NET
For Each f In Directory.GetFiles()
Dim lvi As New ListViewItem
lvi.Text = f.Name
[code]....
The exclusion list works great, but it duplicates each item in the ListView several times. How many depends on how many items that it excludes.
I understand why it's happening, but I can't figure out a way around it. I have to loop through the items in the ArrayList so that I can compare them to the other items.

I have a class that add extra information about a column for linq2sql (see code below) right now, I have to explicitly tell what column I want that info on, how would you put that code with a loop on every column in every table from a dbml file? I was doing my test on a very very small DB, now I have to implement it on a much more bigger database and I really don't want to do it manually for every tables/columns it will take hours.
how it's being used:
Partial Class Contact ''contact is a table inside a dbml file.
Private _ContactIDColumn As ExtraColumnInfo
Private _ContactNameColumn As ExtraColumnInfo
Private _ContactEmailColumn As ExtraColumnInfo
[Code]....

I 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.

I'm trying to set something up where the user can sort each column by clicking on the header... i've looked at some other examples and they seem pretty longwinded..so far i have the below...
VB
Private Sub resultsListView_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles resultsListView.ColumnClick
Dim oldsort As SortOrder
[code]....
which works fine... but only for the first column in the list view.Is there a way of specifying which column to sort based on which is clicked?

I am currently using a recursive search to get all of the files in a directory as well as in all subdirectories of that directory. At the moment (as a temporary solution to make sure the script worked) I have all files with their respective directories listed in a listview (2 separate columns).

I have a listvew that is setup like:
[COLUMNHEADER1] [COLUMNHEADER2] [COLUMNHEADER3]
[CHECKBOX] Graham
[CHECKBOX] Greg
[CHECKBOX] David
What i was trying to do is put text in [COLUMNHEADER3] besides each of the names, so if "Graham's" details exist then put "PASSED" beside the name "Graham" and "FAILED" if it's failed, i'm not sure how to access the 3rd columns details to put that in is it:
formname.listview1.subitems("")

ok in vb6 i would use this to check all items in a listview.
[Code]...
Now Here's my confusion. And i spotted at least one other person on here who was asking the same thing about this.But got no real clear answer that i could see. as a test to compare i tried his suggestion and loaded the same listview up in both a vb6 app and a vb.net app..The list i used was quit large so the comparison would be very through..my list was in the 80,000 lines range tho..yeah talk about overkill The vb6 app checked/unchecked the items within a matter of milliseconds..the vb.net took an extremely long time tho..well not extreme but was very noticeably slower about doing the loops.

I call the following
VB.Net
Public Sub LoadXML(ByVal file As String, ByVal ListViewName As ListView)
Dim XMLfile As New XmlTextReader(file)
[Code].....
However, no errors are shown, the items are not added to the ListView. Also, if i check the values of "artist", it is populated, as are the rest. It just, for some reason, does not add to a listview on another form.

I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

I have a listview that I add items to by loading from a file, and that works fine. I then edit the items or add new ones, and on form dispose, the file is supposed to be saved containing the listview items, but when I step through this process, mylistview.items.count is said to be zero, which I know is not true because I can see the items right on my screen, I added them myself.[code]I use this same method for saving and loading to and from listboxes, and it works fine.

I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:
[CODE]...
How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?
