When I add an image to the imagelist, the con shows up. That's fine Let's say that I added 4 images (four items to the listview) then remove one item from the listview. From there, the next item I add will adopt the previous image added. How can I keep this from happening?
I've got a list view that opens items inside a folder and displays them. I want to know if there is a way to have the list view display the icons as well, maybe using shell32 or an imagelist. Here's the code:
Imports System.IO
Imports System.Xml
Imports System.Runtime.InteropServices
Imports Microsoft.VisualBasic
Public Class cv7import

Here's two images, of how it looks and how I want it to look.

How can i set an icon from imagelist to the property of .icon of TrayIcon?When I write TrayIcon.Icon = ImageList.Images(n) or ImageList.Images.Item(s) they give me an error with incompatability of image and icons format!How can I set different icons to TrayIcon from ImageList? Or there is a different component to do that?
View 2 RepliesI'm trying to figure out how I can change a ListView's "Large ImageList" to another one at runtime. For example I have it attached to my Icons_64x64 ImageList right now but would want an option to switch it to Icons_128x128 at runtime. Hope that makes sense and someone has an idea out there. I haven't been able to come up with anything at all.

I tried this way and couldn't success.
I have been trying to create a listview in detail mode which has 2 images (a light is on and one with the light off which represents a boolean value) I have gotten some code which populates the Listview during runtime but i have tried various ways to get the images into this without any success, google has been particularly useless and most examples seem to involve creating an array for each row(great if you have all the data in the first place, my project will perform like a log, it will show an Id, a Name and then 2 colums which should have on/off icons in them.
This is my sample code which works by creating a ListViewItem, adding the items for the row and then adding it. When i did this on my project however it showed nothing in the view (presume i need to refresh it after each add?)

Private Sub Form1_Load(ByVal sender As System.Object, _

but the problem is that he don't print the icons.And this I never have to test until nowI can add anything like a color and other stuff but I do not know how to solved this.

I am trying my hand at .Net 2010. I played around with vb6 for years but now it has come time to do .Net. So I am making a Explorer type app where I have a treeview on the left and a listview on the right. I have all that working fine I now want to add icons to the files listed in the listview. My app calls function in a class file and it populates the listviewHow do you add (dynamically) the icons from the files shown? Below is the function in the class file I have, not the form file.
Public Function ListFoldersFiles(ByVal path As String, ByVal lvTemp As ListView, Optional ByVal sExtFilter As String = "*.*")
' Create a reference to the current directory.

I'm a VB beginner. The following image comes from a Mac application that I've developed. This window lists all visible files and their icons for a particular folder.

The issue I'm running into is that 1 folder I have has 812 files in it and it takes a good 20 seconds or more to load the files with their Extracted icons.
Furthermore, I ran into one instance where a .pdf file was given a system icon (sort of like the icon a .bat file would receive with the two gears) instead of the Adobe PDF icon.
So, my questions are: 1) Is there a better way to load files so that it will be able to get the icons and display them in the Listview faster?
2) Is there a better way of getting associated icons since the VS built in option seems fallible.
I am trying to add icons to a listview that would contain a list of programs added by the user. I am pulling my hair out over this. I had the solution a few days ago and then I decided to go in another direction and then cleared my browser history. I have searched for that code for awhile now to no avail.

I want display many items in a Listview.Each Item gets a own icon.Item 1 to 32768 = Icon is visible in ListviewItem32769to 65536 = Icon is not visible in ListviewItem65537to ... = Icon is visible in ListviewI think it swaps in 32768 steps.Here is my code:
Dim tmpIcon As Icon = GetIcon("...")

I have created a project that uses a listview associated to an imagelist (LargeImagelist, I have set the size as 100 x 75 and 32 bit depth), that displays information from a database along with an image from the image list. My listview is set to tilemode so that I can control the size of the tiles to get two columns of six. The image list is populated when the form is loaded from all the images in a specific folder, this part is working appropriately as I can get a picturebox working consistently that references an image from the imagelist.

I need to obtain a list of desktop icons and add them to a ListView. I'm currently doing this:
[code]...
It points to the direct path the icons should be located under the user profile. However, for some reason I've yet to determine, not all of the icons are in this directory.
I have a program where I'm trying to clone icons in a folder and represent the files in a listview on a form. I've tried using msdn, google and F1 help to figure this out, but I don't seem to be getting it.Here's the code I have so far, but I'm getting error that object not set to an instance of the object.

I have a list view control and for each item I set to display an icon it will change the icons for the other items that already have icons, to the most recently added icon.
Here is my code.

Dim fileandparam As String = IconsInfo(ext).ToString

Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.
