RESOLVED: Learning databases, problem with tutorial: VB.NET 2005

[Og_ofthejungle]

I'm trying to get the hang of .NET databases, after having a decent grasp of them in VB 5.0. It's a new animal, though, so I'm starting with a fresh mindset.

I found this tutorial by Mendhak,
http://www.vbforums.com/showthread.p...8-Tutorial-%29
but when I try it, I get an error

Error 2 Name 'conn' is not declared. ...

which seems to refer to the line in the tutorial

conn.connectionstring = "provider=microsoft.jet.oledb.4.0;datasource=c:\sample.mdb;user=Admin;password=;"

so I inserted this line just above it:

Dim conn As New OleDbConnection 'trying to declare "conn" to clear an error

Which clears that error, but on trying to run/debug (page 2 of tutorial) I get an error which highlights the line

da.Fill(ds)

The entire code section looks like this:

Imports System.Data.OleDb
Public Class Form1
Dim ds As New DataSet
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim conn As New OleDbConnection 'trying to declare "conn" to clear an error
conn.ConnectionString = "provider=microsoft.jet.oledb.4.0;datasource=c:\sample.mdb;user=Admin;password=;"
Dim strsql As String = "select employeeID, FirstName, LastName, Location from tbl_master"
Dim da As New OleDbDataAdapter(strsql, conn)
da.Fill(ds)
If ds.Tables(0).Rows.Count > 0 Then
TextFirst.Text = ds.Tables(0).Rows(0).Item("FirstName").ToString()
TextFirst.Text = ds.Tables(0).Rows(0).Item("LastName").ToString()
TextFirst.Text = ds.Tables(0).Rows(0).Item("Location").ToString()
TextFirst.Text = ds.Tables(0).Rows(0).Item("EmployeeID").ToString()
End If
End Sub
End Class

I did download the sample.mdb file, and placed it at c:\sample.mdb, as I have referenced it above.

Any advice or comments would be welcome.
