I'm having some more trouble with working with arrays. My assignment is to take an input file of 10 numbers and display the original array, the array reversed (1st element is last element, etc.), the average of the parallel elements (nth element of both arrays), the average of the original array, and the elements greater than the average. I know I need to load the file into an array. However, I can't seem to figure out how to reverse it, nor average the two even if I can get it reversed.

I am working on an assignment where I need to have a product list that is loaded into a list box upon the form loading. This is generated from a txt file in the /debug folder upon loading. Now my question is how do I have the product names show up in the list box when there are 3 separate parts to each product. The product, the cost, and the quantity in inventory, and all I want to show up is the product in the listbox, where the rest show up elsewhere.
CODE:
'This procedure loads the data for the array from txt file. As well as loading the Product.txt file into the system when the program loads.

I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.

I am trying to make a MVP kinda system and I am trying to define and load an array, through the system. Then read it out and it should populate a ListView1 object.I know they are set correct, because the console tells me it's set ok.I know the sample would fill with the same item (a week to be exact) every time i add an item, but that's not the point.Also, is it possible to define the array without the index, i mean now i set it with (6) so it sets 6 blocks for strings, but I would like to be more flexible. Is there a way like in php for example
$item["firstname"]
$item["lastname"]
...
ClientlistItem.vb (definition of the actual item)
Public Class ClientlistItem
Private entry(6) As String[code].......

I accomplished the task of creating a picture viewer that finds pictures in a directory,adds them to a listbox, and displays them in a picturebox at intervals using a timer. Now, I am trying to achieve a similar task using an array in a continuous timer-display fashion so that after the last image the process starts over from the first image again

I have a form that contain 30 image (load by array) and when one of the image clicked, the background of my frmMain should change to the image clicked. The program has no problem by launching the code below :
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picWallpaper1.Click
frmMain.BackgroundImage = picWallpaper1.Image
End Sub
Private Sub PictureBox2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picWallpaper2.Click
[Code] .....
But this way is not effective if I want to increase more image up to 50,60 in future the program will loaded with these code.

Okay, so I have been developing my own MP3 player recently, and now I thought I would make the player remember what songs were in the playlist when it shut down. It now remembers the playlist file that was used last, but I would still rather make it so that it remembers all the songs without saving the playlist.
I've been using a setting to save the playlist file, but when I try this:
...it doesn't work. The savedSongs is a System.Collections.ListArray. Heres the code at Form_Load I'm using at the moment.
Dim loadSongs As New System.Collections.ArrayList
loadSongs = ExperimentalPlayer.My.Settings.savedSongs
lbl_songname.Text = ""
[Code].....
Should I use some other kind of variable to save the filepaths? Well, the other option is that I use a text file for that, but I'd rather make it like this.

have a lot of experience with LINQ, but should your verb be attached to the array?
data.Tables("people").LoadDataRow(parsed(int1, 1), True) S/B
data.Tables("people").LoadDataRow(person.parsed(in t1, 1), True)
