How To Listview1.items.addrange(arraylist1)

May 2, 2011

i was trying to paint a row of a listbox item but ppl said that listview item is much better than a listbox and has the ability to paint items, what i couldnt get it to work however is to add an arraylist to the listview what ive tried was the following:

datasplit.AddRange(progressload.Split(New Char() {"'"c}))
Dim items As New List(Of ListViewItem)
items.AddRange(datasplit.ToArray)

[code]....

Is there any easy way to add an arraylist to listview?i forget, is there a possibility to make listview order items like a listbox? i dont want from left to right then down then left to right then down... etc I want them to be top down and keep like that no matter the dimensions of the listview.

DataTable To ArrayList Using AddRange, No Zeroth Element?

Jun 5, 2011

I am trying to populate an ArrayList using the elements from a DataTable. I know I could do this using Loop, but I am trying to figure out how to using AddRange.Here's my code:SomeArrayList.AddRange(SomeDataTable.Rows.Item(0).ItemArray)

The problem is that I can pass the collection except for the Zeroth element.

This is the collection I am trying to pass to the ArrayList:
1. Dog
2. Cat
3. Bird

This is what I got 1. Cat 2. Bird

Public Sub CheckUnPw()
For Each prox As ListViewItem In ListView2.Items
For Each port As ListViewItem In ListView3.Items
For Each un As ListViewItem In ListView4.Items

[code]....

This is my thread, everything works fine. But i have a big list of proxy severs. ListView2 contains the proxy servers and ListView3 contains the ports. When a server response with nothing the proxy + port is removed from the list. But i want that if a proxy is valid that it's moved to LisView6 & 7.Now i've marked the placed where the problem occurs.

The error: Cannot add or insert the item '213.13.27.247' in more than one place. You must first remove it from its current location or clone it.Parameter name: item Removing from ListView2 & 3 goes fine but adding the same to ListView 6 & 7 goes wrong.

Moving MP3 File From Listview1 To Listview2

Jan 25, 2009

Basically what I want is when a person clicks on an Item that ends in "Mp3" in Listview1 to then Create that same File on Listview2 So far It will create the File, not show its name. and it gives the directory, but not all the way.

Heres the Code for Moving the file to listview2.
If ListView1.FocusedItem.Name.EndsWith(".mp3") Then
ListView2.Items.Add(ListView1.FocusedItem.Name.ToString, 4)
'Add SubItem Information.
Dim li As New ListViewItem
li.ImageIndex = 4
[Code] .....

I wont get anything to pop out on Listview2, even if I click anything on listview1. I have to group (left click and hold, and go over multiple items.) And if I am lucky I will get some stuff on Listview2. I got 1 item to move to listview2 but it has no name (it does not appear). Now if we move the scroll bar to the right, we will see another error, (next picture). The Directory Does not end with the Music's Name.mp3. And It does not even end in the same directory as the textbox on the bottom right corner?

VS 2008 - Linq Statement To Go Through A Dropdown Menu's Sub Items And Get What Items Are Checked

Apr 8, 2010

I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False

I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there

However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
