Loop Through All Selected ListView Items

Oct 7, 2011

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.

A first chance exception of type 'System.Net.WebException' occurred in System.dll
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.Windows.Forms.dll

VS 2008 Nested Loop Duplicating ListView Items?

Jul 29, 2010

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.

Adding Items To A Listview As Well As Checkboxes And Tag Property

Jun 14, 2011

I've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.

But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.

This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)

'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)

[Code]...

But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)

Adding Items To ListView In Separate Thread?

Jan 26, 2010

For some reason, the following code is causing me some issues. This code pulls lockout status data from AD and contains the data within a datatable. An event is raised from the threaded procedure to add the data to a listview control. For some reason one row of data gets added to the listview control and when you run the procedure gain, 2 rows of the same data gets added, and then 3 rows, etc.

This code calls the procedure "CallGetUserLockout"
GetLockoutStatusToolStripMenuItem.DropDownItems.Add("For Current User - " & User, Nothing, AddressOf CallGetUserLockout)
