Same problem, you can't create (and are obviously not creating) an OS in VB.Net 2008.
All you're doing is piggy backing on the existing OS by calling the Win API.
Perhaps you should reframe what you are trying to achieve?

Maybe he won the bid to create that Windows XP-like OS for $20-100.

I did once write a DOS which took many hundreds of hours, written in C. Not as functional as DOS 6.0 was at the time, but it was a neat college project.
A windows operating system on the otherhand takes tens of millions of development hours, usually encompassing thousands of developers.
Thus to do what you propose you'll need to:
(a) Let's optimistically assume it'll take 1m man hours. So working 16/7/365 you should be finished in 2180 ish sort of time frame. You are in good health I hope?
(b) Skilz in C/C++ and assembler. Make sure you know which hardware configuration you're going to target. Which CPU family were you thinking of?
(c) The BIOS is your friend for simple stuff, be prepared to write an awfull lot of assembler when it doesn't do what you need.
(d) Intimate knowledge of hardware, you will need to write all the device drivers you know. You think that mouse you're using just magically works?
(e) Ever written a windowing system yourself? This nice caract I have here flashing as I type doesn't come free you know. You'll even have to code the loop to do that.
(f) This is perhaps the hardest .. understand that writing a Windows application in .Net that calls the Win API is not remotely similar to the monumental and derranged task of writing your own OS, since it's patently and painfully OBVIOUS to all that it's running on an OS and the calling that damn OS' shutdown method ... seeesh.

You'll have to ask Infragistics that question. Click here[^]. When you paid for the controls, you also paid for support. You DID pay for the controls, correct?

I doubt very much that anyone could create a smartphone with vb.net, although you could write a program in vb.net for one. 
In all seriousness, there are entire books written on this subject. Try Googling VB.NET Windows Mobile[^], see what you get.

Okay, so I'm trying to make a program that refers to a table of prices for various items. The problem I am having is being able to easily retrieve data from the CSV file... I can read from it, but I want to store it to an easy-to-use lookup table so that I can pull whatever kind of information I want at any given time.
To test this, I tried to make a program that consists only of a listbox, which upon loading of said program would be populated with the names of all of our items. But so far, I cannot figure out how to store this data.
I tried using a multidimensional string array, but for some reason my code isn't working. It seems like the program gets to a certain point in my code and stops doing what it's supposed to do, and the functions end and I'm staring at my form.
Can anyone help me with this? I would really appreciate it!
Imports System.IO
Imports System.Data.OleDb
Public Class Form1
Dim ITEM_FILE_PATH As String = ""
Dim ITEM_FILE As String = ""
Dim ITEM_LIST As String(,)
Dim ITEM_LINE As String()
Dim fs As FileStream
Dim sR As StreamReader
Dim frstComma As Integer = 0
Dim thisLine As String = ""
Dim NumLines As Integer = 0
Private Sub ReadCSVFile()
ITEM_FILE_PATH = Application.StartupPath & "\All_Item_Prices.csv"
fs = New FileStream(ITEM_FILE_PATH, FileMode.Open)
sR = New StreamReader(fs)
sR.ReadLine()
'ITEM_FILE = sR.ReadToEnd
While sR.EndOfStream = False
thisLine = sR.ReadLine
NumLines += 1
'MsgBox(thisLine)
frstComma = InStr(thisLine, ",")
thisLine = thisLine.Substring(frstComma, thisLine.Length - frstComma)
frstComma = InStr(thisLine, ",")
thisLine = thisLine.Substring(frstComma, thisLine.Length - frstComma)
frstComma = InStr(thisLine, ",")
thisLine = thisLine.Substring(frstComma, thisLine.Length - frstComma)
'MsgBox(thisLine)
Dim COMMAS As String = ",,"
For i As Integer = 2 To 6
'MsgBox(COMMAS)
thisLine = Replace(thisLine, COMMAS, "")
'MsgBox(thisLine)
COMMAS &= ","
Next
'ITEM_FILE &= thisLine & vbNewLine
'For iC As Integer = 0 To thisLine.Split(",").Count
' ITEM_LINE(iC) = thisLine.Split(",")(iC)
'Next
MsgBox(thisLine)
MsgBox(thisLine.Split(",").Count)
For iC As Integer = 0 To thisLine.Split(",").Count
ITEM_LIST(iC, NumLines) = thisLine.Split(",")(iC)
MsgBox(ITEM_LIST(iC, NumLines))
Next
End While
sR.Close()
fs.Close()
'MsgBox(ITEM_FILE)
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ReadCSVFile()
For iCount As Integer = 0 To NumLines
MsgBox(iCount)
MsgBox(ITEM_LIST(0, iCount))
Next
End Sub
End Class
Any help? Thanks in advance!

I think you need to use a DataTable.
Create a DataTable and add columns as necessary, then read your csv file line by line, and for each line create a new row, move your data to each column within the row, then add the row to the DataTable.
You can now use a DataView to filter and sort your data, and you can bind the DataTable to controls such as ListBox, DataGrid etc. You can even write the data back to an XML file.

Steven has the right of it - use a datatable and dataview. However if possible store the data as XML then you can read/write it with 1 line:
dataset.ReadXML(sfileName)
saves all that crap reading in the CSV. Only issue it that it is not human readable but you can always output to CSV if required.

So, I followed your advice and tried going with a data table. However, my code is just plain not producing results.
I frequently ask my code to msgbox me values here and there to see what's going on, and the last batch of code I posted, as well as this one, seems to ignore these msgbox requests, or the code is somehow not executing. I'm not getting a message box.
Below is the sub that I run when the form loads:
Private Sub ReadCSVToDataTable()
'http://vbcity.com/forums/topic.asp?tid=119121
'Dim dt As New DataTable 'class level
'in a method
Dim constr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\;Extended Properties=""text;HDR=Yes;FMT=Delimited"""
Dim conn As New OleDbConnection
conn.ConnectionString = constr
Dim cmd2 As New OleDbCommand
cmd2.Connection = conn
cmd2.CommandText = "Select * From All_Item_Prices.csv"
Dim da As New OleDbDataAdapter(cmd2)
Try
da.Fill(dt)
Catch ex As OleDbException
MessageBox.Show(ex.Message)
End Try
Dim row0col1 As String = dt.Rows(0).Item(1).ToString
'In the above code, the following assumptions were made:
'1) file is located in F:\ directory
'2) file name is testA.txt
'3) the file is a comma delimited file
'4) the file does not contain a header row
'MsgBox(dt.Rows(1))
End Sub
Any ideas?

Ah sorry you got the wrong handle on the solution I proposed.
1. Read in the CSV file as you are doing now.
2. Move it to a datatable
3. Use the data in your app
4. Write the datatable to an XML file
Discard the CSV file
Replace 1 with read XML file into the datatable from now on. CSV is great for transporting large loads of data (XML is NOT) but XML is easier to work with.

But... I can't move the data to a Datatable. That's my problem. It isn't working.
Is there something wrong with my code? I tried doing it that way, and also reading the file line by line as previously suggested. The data stops being read after like, the third column. And I don't know why.

Your existing code puts the data into a list of items, can you successfully create a datatable based on the first row from the CSV file?
Can you load any data into the table?
Is the file a well formed CSV file?
Have you stepped through the process using debug to identify the error?

I haven't really figured out all of the debugging tools yet, to be honest. I'll have to try the step through thing (when I get time, tomorrow probably).
And I can load any data into a datatable, I've done it before. The CSV was an Excel spreadsheet that I exported, so I think it's well-formed.
But what could cause the code to just stop executing at a certain point? I have it clearly setup as a For loop to run until 114 or something, and it stops at like, 3.
