for modification?

Hi MJ,

If it is a fixed array you can do making a shared class as this

Public Class mySample
Private Shared myRealArray As Integer() = {1, 2, 3}
Public Shared Property MyArray() As Integer()
Get
Return myRealArray
End Get
Set(ByVal Value As Integer())
myRealArray = Value
End Set
End Property
End Class

Now you can use everywhere that array by
mySample.myArray(2) = 4

But have a look at arraylist also, because this is not such a nice example,
I did try to answer your question exactly as you was asking. If you want to
redim your array, you have to add a method to your class. (public shared Sub
or function)

I hope this helps,

Hi,

In addition to Cor's comments you need to make a public array in a
module to make available through the project.

Public myArray() As Integer = {1, 2, 3}

Sorry for trying correctiong you, but I think you did want to say

Place the array declaration in a module or a class (declared as
'Shared'), for example:

\\\
Public Module Globals
Private m_MyArray() As Integer

Public Property MyArray() As Integer()
Get
Return m_MyArray
End Get
Set(ByVal Value As Integer())
m_MyArray = Value
End Set
End Property
End Module
///

Access the array with 'Globals.MyArray'.
 
I thought that as well Cor.

I prefer your method to create a Class rather than declaring an array in the
Module

MJ,

You might also want to create an isChanged event in the class to
notify the other form when one changes it.
 
OHM,
I prefer the shared variable in a Class (Cor's example) as well, as its
better "encapsulated". Other developers know that the array is coming from
that class, where as with a Module the array could be coming from any number
of modules.

I normally only use Modules for truly global functions, such as Math
functions. However even then sometimes I will make a class with only Shared
functions.

erm. Thats what I said !

OHM,
Yes I was agreeing with you & Cor!

I did not mean to confuse you, it was more re-iterate what you stated, plus
add a caution of using modules in general...
