I know this sounds kinda boring, but.... In you're opinion, what is the best way to read/write?

I'm using:

Code:
Sub LoadFile(sFileName as String)
Dim Temp as String
Open App.Path & "\vector\" & sFileName For Input As #1
   Input #1, Temp
Close #1
End Sub
Anyway, you get the Idea. So, how would I maximize my code If I wanted to Read/Write the Data From a User-Defined Type?

This is what it's probably going to be:
Code:
Option Explicit

Public Enum vgfNodeType
   vgfLine = 0
   vgfPolyLine = 1
   vgfFilledPoly = 2
   vgfInline = 3
End Enum

Public Type RGBInfo
   R As Single
   G As Single
   B As Single
End Type

Public Type Node
   NodeType as vgfNodeType
   FilledColour As RGBInfo
   LineColour As RGBInfo
   LineStart() As POINTAPI
   LineEnd() As POINTAPI
   AntiAliased As Boolean
End Type
(by the way, I have POINTAPI defined as well)

So, my question is, what would be the best method for writing and reading the Node UDT?
