I want to add files with its icon to a listview control. So I used the below code.But the files names are with its full path. I want to get only the file name without full path and extention. How to modify this code?

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 ext As String = Strings.Right(e.Item.Text, 4)
Dim fileandparam As String = IconsInfo(ext).ToString

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 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?)
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load

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'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.Runtime.InteropServices
Imports Microsoft.VisualBasic
Public Class cv7import

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.

If (File.GetAttributes(f) And FileAttributes.Hidden) <> FileAttributes.Hidden And (File.GetAttributes(f) And FileAttributes.System) <> FileAttributes.System Then

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("...")
ImageList1.Images.Add(tmpIcon)
tmpIcon.Dispose()

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'm developing an application that extracts all the icons of a .exe file or a .ico file. the ExtractAssociatedIcon in System.Drawing.Icon only do this for the first icon which is 16x16. I would be able to extract the other formats like 64x64 or 128x128. I know that there is a Windows API that may help me, but i don't know how to call its methods or even how to use that.

I am trying to do the same with files in a specified directory:
vb.net
[Code].....
When I use this code, I get an error stating: "'MainModule' is not a member of 'System.IO.FileInfo'." If I remove the very first line of the sub that specifies the directory, that error obviously goes away.
So, is there another method of extracting the icon? Or must I declare the directory in another way?

View 1 RepliesWhen I open a form in my application and I maximize it, the Icon and the ControlBox are merged in the menu of the MDI parent where I open the form in. That is perfectly normal.
But when I close that form and open an other and also maximize it, I get two icons and two control boxes in my menu. When I close that form and open an other again and maximize it on it's turn, I get 3 icons and 3 control boxes in my menu. When I close the maximized form shouldn't the icon and the controlboxes dissapear?
I have 3 forms, one frmMain - main form, second is frmUserType- childform, and the last frmCreateUserType. In the main form I have a menu item to open my frmUserType, In this form I have a button to open another form which is my frmCreateUserType, In this form I have a button to add records then update the listview in frmUserType. The problem is the listview will not access with my add button control in frmCreateUserType. I tried not to used mdiparent declaration for my frmMain and frmUserType as children and it works, so meaning that the problem is showing my frmUserType as childform?I am using vb.net 2008

I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?
View 4 RepliesI have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?
I have been able to associate a listview control with an imageview control to display images. There are a couple of things, I would like to do.
