'DataSet1' is not declared. It may be inaccessible due to its protection level.

Question

Hello,
I am sorry if this has been asked elsewhere but i can't seem to find an answer that will help me.
I am using visual studio 2013 and a data connection database from Microsoft access called RFID.mdb (which i made by editing the sample Northwind.mdb file)
I have followed the Microsoft tutorials on how to connect a database and make a data set and i know have the database and dataset in the solution explorer,
All i simply want to do is load the data i have from a text file into this database, i can load the data from the text file but i cannot seem to get the data into the data set so i can add it to the data base.
The error i get is on
'RFIDDataSet1' is not declared. It may be inaccessible due to its protection level. On line 24 and 29.
I have tried removing the "1" as suggested and this gave me "Reference to a non-shared member requires an object reference."
I am not sure what i am doing wrong or what could be wrong, could anyone offer some help?
I am using visual basic.
Code:
Imports System.IO
Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim fileReader As String
        fileReader = My.Computer.FileSystem.ReadAllText("C:\gobetwino\Project\testlog.txt")
        MsgBox(fileReader)
        If File.Exists(fileReader) Then
            Dim iofile As New StreamReader(fileReader)
            Dim ioline As String
            Dim DandT, Reader, Id
            ioline = iofile.Readline
            While Not ioline = ""
                Dim mysplit = Split(ioline, ";")
                DandT = mysplit(0)
                Reader = mysplit(1)
                Id = mysplit(2)
                Dim newImportRow As RFIDDataSet.ImportRow
                newImportRow = RFIDDataSet.Import.NewImportRow()
                newImportRow.DateTime = DandT
                newImportRow.ReaderNum = Reader
                newImportRow.TagNum = Id
                RFIDDataSet1.Import.Rows.Add(newImportRow)
            End While
        End If
    End Sub
End Class
Error lines:
newImportRow = RFIDDataSet1.Import.NewImportRow()
RFIDDataSet1.Import.Rows.Add(newImportRow)

Answer 1

I already have a dataset when I connected the database.
In my solution window I have:
RFID.mbd (which has a single table called "Import" with the sections "DateTime", "ReaderNum" & "TagNum")
RFIDDataSet.xsd
What I am mainly trying to do is load the data from the text file "testlog.txt" to the database RFID.mdb.
I have been following the Microsoft tutorial and it said to use a dataset.
Thus my code currently now looks like this:
Imports System.IO
Public Class Form1
Dim RFIDDataSet As New RFIDDataSet
Dim ImportTableAdapter As New RFIDDataSetTableAdapters.ImportTableAdapter()
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim fileReader As String
fileReader = My.Computer.FileSystem.ReadAllText("C:\gobetwino\Project\testlog.txt")
ImportTableAdapter.Fill(RFIDDataSet.Import)
MsgBox(fileReader)
If File.Exists(fileReader) Then
Dim iofile As New StreamReader(fileReader)
Dim ioline As String
Dim DandT, Reader, Id
ioline = iofile.Readline
While Not ioline = ""
Dim mysplit = Split(ioline, ";")
DandT = mysplit(0)
Reader = mysplit(1)
Id = mysplit(2)
Dim newImportRow As RFIDDataSet.ImportRow
newImportRow = RFIDDataSet.Import.NewImportRow()
newImportRow.DateTime = DandT
newImportRow.ReaderNum = Reader
newImportRow.TagNum = Id
RFIDDataSet.Import.Rows.Add(newImportRow)
End While
MsgBox("Update successful")
End If
End Sub
End Class
I am not sure if what I am doing is correct because the program now shows the results in the message box instead of "Update Successful".
Does this help in finding out what I am doing wrong when trying to load the data from my text file into a dataset which I then plan to use to update the database RFID.mdb
