Loading A Text File into a Array into a Listbox

May 8th, 2008

I am usually not keen for asking for help in these kind of situations but I am really stumped when it comes to this, all I really need is a good step in the right direction and I should be (hopefully) fine.

I am currently writing an airplane seating program for my VB class. What I am trying to do is load a text file into an array and then out put it into the list box.

Help with Code Tags

Language Syntax (Toggle Plain Text)

        Dim seat(15, 6) As Double
        Dim sr As IO.StreamReader = IO.File.OpenText("plane.txt")
        For row As Integer = 0 To 6
            For col As Integer = 0 To 15
                seat(row, col) = CDbl(sr.ReadLine)
            Next
        Next
        listSeat.Items.Clear()
        listSeat.Items.Add("ABC DEF")
        Do While sr.Peek <> -1
            listSeat.Items.Add(sr.ReadLine)
        Loop
        sr.Close()
    End Sub

The setup for the txt file is like this:

... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...
... ...

When I execute the program I get a InvalidCastException which said {"Conversion from string "V.. ..." to type 'Double' is not valid."}

The "V.. ...." is from the txt file, from this error from what I am trying to comprehend is that its trying to convert the whole line to double, but I am not sure on how to go about going fixing this small problem, because If i can figure this out then I can figure out the rest of my problem.

Thanks in advanced
