View 4 RepliesForms :: Speed Up Loading MP3 File Info Into ListView
Apr 27, 2010It has the ability to recursively grab all .wmv and .mp3 files in any chosen folder, and add them to a playlist.When opening the playlist, my program adds all the songs to an array, then starts adding the songs to a listview, categorizing them by song, artist, album, and genre, using a dll to access the ID3v1 tags on the .mp3 file.It can successfully create playlists of thousands of songs at a somewhat okay speed, the problem is loading that into the categorized listview.It used around 75% of my friend's CPU while loading his 5k+ song playlist into the listview, and it never finished after loading it in for a couple minutes (it auto updates as it loads, because it is done in a new thread.) It never finished because his OS has a bug where, if the CPU usage is over 100% for more then a few mins, it BSOD's, but that's beside the point.
His CPU, by the way, is a quad core 2.33 GHZ processor.The listview loads thousands of songs by using a lot of CPU [low amount of RAM, less then 40MB 99% of the time], and it does it slowly. [code]I've already redone the sub once or twice to speed it up, and at the moment it's 2-3.,

[2008] Loading Data Into A ListView In WPF?
Jan 17, 2009I'm trying to build an app using WPF and I want to display a load of data from some tab delimited log files in a data grid style. I know there is no DGV control for WPF so after watching a few "forms over data" videos on the MSDN site I figured I should be able to do it using a ListView with DataGrid tags within it.So after messing about with the XAML code for a bit I managed to create my column headers in my ListView etc and I can load data into it fine if there's just one column... but obviously I need more than one column.
So I thought fine I just create my extra columns and then use ListViewItem and ListViewSubItem classes to create the content for the listview and then add them to it. However, it seems that ListViewSubItem does not even exist in WPF and the ListViewItem doesnt seem to have any way of editing separate column data. For example, if I set ListViewItem.Content = "some text" and then add that to the ListView it just sets "Some text" in all 5 of the columns I have.All of the examples on MSDN are using data bound listviews and I dont want mine to be data bound I just want to manually load it with items.

View 10 RepliesVS 2008 - How To Access Listview Data - Program That Contains A (listview) Control
Sep 22, 2009I 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?

Sep 14, 2011I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected
Dim items(0 To 3) As String
items(0) = "One"

Loading An Image Saved As Type 'Attachment' In An Access 2007 Database?
Jan 31, 2012I'm having a problem that I've spent all day researching to try and figure out. It seems that the 'Attachment' type in an Access 2007 DB file is stored as three seperate pieces of data in the one field. If you open up the Relationships view, you can see it in the table itself.
I'm trying to do a simple DVD movie database to keep track of everything I have, and who I've loaned things out to. I'm doing this in part to further my education in VB.NET and to figure out some of the things involved with interacting with databases. I haven't actually written any code yet, read on and you'll understand what's going on.
I've got an Attachment field setup in the database to hold a picture of the movie poster or DVD cover art or something like that to help identify the film, and I named it 'Art' of type 'Attachment' since that will hold an image. Looking at the table in Access I see that 'Art' is broken down into three entries: Art.FileData, Art.FileName, Art.FileType. I'd like to be able to pull the filename and file type and display those on the form, but we'll get to that later.
When I use a drag-n-drop gridview of the database into my blank VB form, the Art field just shows the filename, in my case it's 'screenshot.png' since I just dumped a screen shot in as a test. So, the gridview on the form will see the field and display the filename, which is fine. If I do another Windows form and drag-n-drop a Details View (instead of the grid view), and have the Art field in the table set to a PictureBox (in the Data Sources view, you can highlight a field and then designate it as text or picture
or date or whatever), I end up with a blank box instead of my image.
I haven't typed any code into any of the forms at this point. I'm still in the Designer trying to get the layout and stuff the way I want it, afterwhich I'll start adding buttons and methods and such to search for things, print out a nice list of the films in the database (with and without pictures) and be able to sort out a list of who I've loaned things to (like an overdue book list). But so far, by just dragging and dropping from the Data Sources into the form, Studio automatically creates the dataset and bindings and such to read from the database file, and I can see all of my test data *except* for the image in the PictureBox (it's just blank/empty).
So, if you want to see what's happening and sort this out, then you need to do the following:
1. Create an access database with a table, that table having at least one field of type 'Attachment'
2. put a picture/image into that field as a first entry
3. in Studio (or in my case Express), create a new project, which'll have a blank form in it by default
4. create your database connection by using the 'Add new data source...' wizard for your Access DB file
5. from the Data Sources, expand the table views and change the attachemnt field from the default of TextBox to a PictureBox (you may have to Customize the types to get PictureBox to show up)
6. drag and drop that whole table onto your form, which will automatically create form elements to display the data and stuff
7. Run it, you'll see the problem.
I have no idea what I need to look at or edit or change to get this PictureBox to display the image from the database. Like I said before, if I leave the type set to the default of TextBox in the Data Sources view, then the field will display the filename of the file stored in that field of the database. Having not typed any code yet, I have nothing that I've done that I can edit other than the automatically created stuff that Studio did when I dragged the table into the form.
Being completely unfamiliar with how VB.NET wants to talk to a database (SQL server, Access or otherwise) I decided to create this little program to learn how to do it. But I ran into this problem and need a little help. What I'm looking for is what I need to change in the bindingSource or TableAdapter or TableAdapterManager or BindingsNavigator or whatever resource is binding the fields on the form to the entries in the database so that the PictureBox will get the part of my 'Art' field that actually
holds the image, not the filename or the type. I don't know how to do that, and that's what I'm trying to learn. What I would like to know is how to both get the image to display in the PicutreBox and pull the filename for that image as well to display beneath it or something in the form.
And before someone starts complaining about writing the whole program for me, I must say this is one element of a large personal project and if you read my entire post here you'll see that there are many other elements that will eventually go with it. I just need some help getting this one thing to work. Multiple web searches and such point to a variety of different approaches, many of
which I've tried to implement but nothing has worked. I'd like to do this entirely in .NET with no other dependencies if at all possible, but some of what I've seen so far today suggests using Interop and other things to make this work, but those haven't panned out for me either as of yet. My ultimate goal with this whole program is to have one (albeit probably large) executable file that will encompass the entire program, and to have it all work. After that, then I'll look into things like creating my own modules
and DLL's and such to thin it out, but I'm not even close to that point yet.
