Phone Book In Vb

[ashblynn02]

I am trying to create a phone book program in Visual Basic. I have so many phone numbers, I thought this would be a neat way to handle the overflow lol. I want it to read the information from a text file with the following data: First name, last name, home phone, cell phone, and e-mail address (with each item of data on its own line, so that each person listed will have five lines with no blank lines between individuals) If any data is missing or does not exist its corresponding line is to be blank.

I want it to be where the data can be searched in many different ways. An individual may be called up by sequence number, and the user is also to be able to browse the names with First, Last, Next, and Previous buttons. And I'm guessing a find button to find the next occurrence which matches the text entered in the search text box.

So far I have whats below, my main problem is that my first name ends up coming in twice and then everything gets pushed down one thing so my email address isn't on there...Can someone please help me :)

Thanks:)

You are getting the first name twice because of this:
FirstName(Count) = Temp.Trim
LastName(Count) = Temp.Trim
Try this:
FirstName(Count) = Temp.Trim
Temp = DataFile.ReadLine
LastName(Count) = Temp.Trim

Yep that worked!!! Now I am trying to have two buttons first and last. So when I am down in the line it will either go to the very first entry or go to the very last entry. How would you do that... so far this is what I have and they are not working!!

{ Private Sub BtnFirst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFirst.Click
If Index > Count Then
Index = Index - Count + 1
DisplayData()
End If
End Sub


Private Sub BtnLast_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnLast.Click
If Index < Count Then
Index = Index + Count - 1
DisplayData()
End If
End Sub
}

can you help me here at all?

THanks :)
