<p><strong>Edit:</strong> This was accidentally posted twice. Original: <a href="https://stackoverflow.com/questions/243900/vb-net-importing-classes">VB.NET Importing Classes</a></p>

<p>I've seen some code where a <em>Class</em> is imported, instead of a namespace, making all the static members/methods of that class available.  Is this a feature of VB?  Or do other languages do this as well?</p>

<p>TestClass.vb</p>

<pre><code>public class TestClass
    public shared function Somefunc() as Boolean
        return true
    end function
end class
</code></pre>

<p>MainClass.vb</p>

<pre><code>imports TestClass

public class MainClass
    public sub Main()
        Somefunc()
    end sub
end class
</code></pre>

<p>These files are in the App_Code directory.  Just curious, because I've never thought of doing this before, nor have I read about it anywhere. </p>

Having written the MyBlogLog plugin (the original one, that is) I found that the Wordpress Hooks list (can't remember the link offhand) was incredibly useful, as was the sample code from the Codex and WP Install files. Reading through other developer's plugins is also a good way to learn, as you can see how they implemented things and use those techniques to save yourself some R&D time.
What are you looking to create, anyways?
Edit:
I posted a comment with this, but just in case it gets lost...
For your specific needs, you're going to want to store data and be able to manage and retrieve it so creating a custom database table in your plugin is something you will want to do. See this codex link:
http://codex.wordpress.org/Creating_Tables_with_Plugins
Then you can just add your management code into the admin screens using the techniques found on this Codex page:
http://codex.wordpress.org/Adding_Administration_Menus
If you want to display the items on a page, you can either write yourself a custom PHP WP Page template to query the DB directly:
http://codex.wordpress.org/Pages#Page_Templates
Or just add a hook filter on your plugin to write the results to the page based on a keyword you specify:
