Interface Newbie

[Mike Hildner]

I have this interface:

Module Interface_Module
    Public Interface ISleuthMobile
        Function GetName() As String
    End Interface
End Module

The module is in it's own project, named "SleuthInterface". Another project in this solution is called "Skids". In Skids, I added a reference to SleuthInterface, because I want Skids to implement SleuthInterface.

In Skids, I import SleuthInterface with no problem:

Imports SleuthInterface
 
Public Class Skids
    Inherits System.Windows.Forms.Form
    Implements isleuthmobile
...

My problem is, the class cannot see ISleuthMobile. If you saw the above code, there's a squiggly line under "isleuthmobile" (I usually write my code to not match the case, because of the visual feedback IntelliSense gives you).

Looks like I'm missing something really basic, but heck if I can figure it out.

Any help is much appreciated,
Mike

Why put the interface in a module? That adds the module name to the namespace. I'd suggest removing the Module:

Public Interface ISleuthMobile
        Function GetName() As String
    End Interface

An interface is just like a class or module and doesn't need to be encapsulated in anything else. Otherwise you'd have to import SleuthInterface.Interface_Module to reach it but as stated there is no need for it to be in the module.

To be honest, I'm not really sure why I'm doing it this way. This is my first attempt at trying to make an extensible application.

The way I understand it, my container application needs to see the interface, as does my (or someone else's) plugins. That way, I can iterate over some dlls in a "Plugins" directory, and load the plugins into my app.

So I thought I needed to make the interface as a stand-alone thing - ready to be used by whoever makes a plugin.

BTW - I really don't know what I'm doing

nm = Never mind

He answered the question, but probly realised it didnt help.

Making my module "Public" seems to have fixed that problem.

Anybody around here ever make an extensible application? The idea is really cool, I'm slowly getting there, probably doing all sorts of stuff wrong
