Good Evening,
I have just signed up in hopes of finding a good explanation to my question. I would like to thank everyone in advance for any help they could give.
Problem:
I am trying to create a "Previous Record" button for a windows form.
Current Setup:
i have a File menu with 2 menu items ( OPEN , EXIT )
i have 2 labels for display purposes ( nameLabel , phoneLabel )
and i have 2 buttons ( NEXT , PREV )
i am using the StreamReader to open up and read from a txt file.
Here is the code that i have on the form.
As the code shows, i am asking the user to specify the TXT file, then the file is open and read. The first 2 lines are then assigned to the Labels.Text
My problem is i would like to setup a previous button to go "backwards" in the txt file.
Is this possible?
Thank You
Tibby

Inherits System.Windows.Forms.Form
Private phoneStreamReader As StreamReader
Private Sub fileOpenMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles fileOpenMenuItem.Click
'Open the file
Dim response As DialogResult
OpenFileDialog1.InitialDirectory = Application.StartupPath
response = OpenFileDialog1.ShowDialog()
If response <> DialogResult.Cancel Then
phoneStreamReader = New StreamReader(OpenFileDialog1.FileName)
nextButton_Click(sender, e)
End If
End Sub
Private Sub nextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nextButton.Click
Dim test As Long
If phoneStreamReader.Peek <> -1 Then
nameLabel.Text = phoneStreamReader.ReadLine()
phoneLabel.Text = phoneStreamReader.ReadLine()
End If
End Sub
Private Sub prevButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles prevButton.Click
