Hi guys,

I am trying to make a small application for the company I work for.
The application has to be able to make a floor plan for a casino.
The casino has to create the map of where all the slot machines are located and if you double click on a certain machine pull some info for it.
So I put a picturebox and divide it in a lot of cells and create a class named CellValue and create and array of object Cell value.
The Cellvalue has some variables cellcolor, cellname, cellshape and cell Location x and y.

My issue now is that I need to save the array so I can re draw and save the map made. and tried several methods to save it using XML serialization but it doesn't do nothing :(
If I do get the array to save how can I access items in the array from outside the method? that doesn't seem to be working as well.

here is the code I have up to now

Imports System
Imports System.Collections
Imports System.Xml
Imports System.Array
Imports System.Data
Imports System.IO

Public Class Form1

    Dim SizeW As Integer = 30
    Dim SizeH As Integer = 30
    Dim Plan(SizeW - 1, SizeH - 1) As CellValue
    'array created of objects from class CellValue 
    Dim Command As Integer = -1
    'Set to -1 if none of the buttons are clicked, can give a function/sub code for this
    Dim RND As New Random
    'To randomize the colors if needed
    Public LocXY As String = ""
    Public mcid As String = ""

    Private Sub btnClear_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClear.Click
        Command = 0
        'This will execute command 0 code below
    End Sub

    Public Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
        Command = 1
        'This will execute command 1 below
    End Sub
    Private Sub btnstrdata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnstrdata.Click
        Command = 2
        'This will execute command 2 code below
        'will be to serialize map to xml

    End Sub

        'Divides the picture box size into cells p.e size =200 and there is 20 array obj each cell is 10px
        Dim P As Point = PointToClient(MousePosition)
        Dim X As Integer = (P.X - PictureBox1.Left) \ CellW
        Dim Y As Integer = (P.Y - PictureBox1.Top) \ CellH
        'Determining which cell is clicked
