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

Dim SizeW As Integer = 30
Dim SizeH As Integer = 30

'Set to -1 if none of the buttons are clicked, can give a function/sub code for this

'This will execute command 0 code below

'will be to serialize map to xml
