Are arrays of objects possible ?

I have an object
Public Class Plateobj Public Order As String Public Row As String Public Column As String End ClassI want to create an array of the Plateobj'sDim plateinfo() As PlateobjAnd then refrence them as followplateinfo(0).Order = "One"But I get the following error "Object refrence not set to an instance of an object" I guess I am doing something daft, any clues welcome Ta Very Much -

Kevin, Thanks tried that and still get the same error (on the initalise). Geoff
try this
'declare the array dim plateInfo() as Plateobj 'set its bounds redim plateInfo(10) 'initialze the array item plateinfo(0) = new Plateobj() 'now work with it plateInfo(0).order = "One" -
try this
'declare the array dim plateInfo() as Plateobj 'set its bounds redim plateInfo(10) 'initialze the array item plateinfo(0) = new Plateobj() 'now work with it plateInfo(0).order = "One"Are the objects in the area always going to be Plateobj? If so you should consider using Generics. Kinds Pseudo Code... in C#, List LobjList = new List(); LobjList.Add(new Plateobj()); LobjList[0].order = "One;
