Global Enum question


B

BobRoyAce

I have a module that defines, among other things, an Enum:

--- MODULE CODE BEGINS ---
Namespace OMEGA.GRP
Module Globals
...
Public Enum FileProcessingStatus
None
Processing = 1
Completed = 2
Failed = 3
End Enum
...
End Module
End Namespace
--- MODULE CODE ENDS ---

Then, in a class module file, I have:

--- CLASS CODE BEGINS ---
Public Class clsFileProcessor
...
Private _ProcessingStatus As FileProcessingStatus
...
Public ReadOnly Property ProcessingStatus() As FileProcessingStatus
Get
Return _ProcessingStatus
End Get
End Property
...
End Class
--- CLASS CODE ENDS ---

This will not compile...get error message:
'ProcessingResult' cannot expose type
'OMEGA.GRP.Globals.FileProcessingStatus' outside the project through
class 'clsInputfeedFileProcessor'. C:\...\Classes
\clsInputfeedFileProcessor.vb

I have only a single project within the solution. I addition, when I
remove the Namespace declaration in the first quoted module, the error
message still occurs.

What am I doing wrong here and how do I fix it? The bottom line is
that I would like to define some global Enums that can be used
throughout the various forms and classes of the application.

Note that this will implicitly mark the module as 'Friend', which is less
visible than 'Public'.
Public Enum FileProcessingStatus
None
Processing = 1
Completed = 2
Failed = 3
End Enum
...
End Module
End Namespace
--- MODULE CODE ENDS ---

Then, in a class module file, I have:

--- CLASS CODE BEGINS ---
Public Class clsFileProcessor
...
Private _ProcessingStatus As FileProcessingStatus
...
Public ReadOnly Property ProcessingStatus() As FileProcessingStatus
Get
Return _ProcessingStatus
End Get
End Property
...
End Class
--- CLASS CODE ENDS ---

This will not compile...get error message:
'ProcessingResult' cannot expose type
'OMEGA.GRP.Globals.FileProcessingStatus' outside the project through
class 'clsInputfeedFileProcessor'. C:\...\Classes
\clsInputfeedFileProcessor.vb

I suggest to remove the module completely. Enumerations are types, so you
do not need to nest them inside modules.
