Structures, Classes, Enums, Oh My!

[Paul]

I have a situation that I want to work but don't know the proper way to
handle it.

I want to create a User Defined "Type" (structure, class or
enumeration). I'm not sure what it should be or where it should
reside. I'll use Enum for this example.

Currently in a Public Module:
----------------------------
Public Enum MyUserDefinedType
A = 1
B = 2
C = 3
End Enum


I have a class with a public method.

Currently in a MyTestClass.vb class:
-----------------------------------

Public Class MyTestClass

Public Sub MyObjectsSub1(ByVal P1 As MyUserDefinedType)
... blah, blah, blah
End Sub

End Class

The syntax error I get in the class for using MyUserDefinedType as the
type for P1 is:

'P1' cannot expose a Friend type outside of the public class
'MyTestClass'.

I want my class to be able to use the MyUserDefinedType, but I want my
other code (forms, other modules, etc.) to also be able to use
MyUserDefinedType. Anyone have any thoughts on this?

Any help would be greatly appreciated.

Paul,
| Currently in a Public Module:

Ah! There's the Rub!!!

I suspect you defined your module as "Module SomeModule" instead of "Public
Module SomeModule" as the default visibilty on modules is Friend.

As you noted Enums are Types just like Modules & Classes. Seeing as Enums
are Types, I normally define them at file level instead of inside a Module
or Class.

When I'm defining an Enum, I normally add a new Class to my project to give
me the file, then I simply delete the Class definition & add the Enum
definition.

Hope this helps
Jay
