We're stumped.

We'd like to create an enumeration like MS does with SqlOleDbType but
for cursor types (in this case). We would like to be able to write
this:

    Public CursorType Cursor
    {
        set {m_cursorType = value;}
        get {return m_cursorType;}
    }

Where CursorType is defined as:

    enum CursorType : int
    {
        wait = 1,
        arrow = 2,
        crosshair = 3
    }

Therefore this can be called as:

    Object.CursorType = CursorType.wait;

The problem is that the enum has to be defined in a class, such as:

    class Globals
    {
        public enum CursorType : int
        {
            wait = 1,
            arrow = 2,
            crosshair = 3
        }
    }

So we have to use the syntax:

    Object.CursorType = Globals.CursorType.wait;

The problem is that we'd like to get rid of the "Globals." prefix. This
could be solved by allowing the enum to be defined at the namespace
level, but we can't do this.

Does anyone know how we can do this or if this is even doable?

Of course, by adding a..

using YourNamespace.Globals;

..to your code, you do "hide" the Globals namespace just like MS does with
SqlOleDbType. That's what I've accepted as the only way to do that.

(by the way, Globals seems far too generic a description. Surely
YourCompanyName.Cursors would be better for that?)

Why can't you define your enum in the namespace? - enums can be declared in
namespaces legally:

using System;

namespace test
{
enum CursorType : int
{
        wait = 1,
        arrow = 2,
        crosshair = 3
}
}

works just fine. It there some design issue you have with this?

Great, we'll give it a try.

And yes, we are prefixing namespaces with a company name and a level or
two more before we actually get to a class name. I shortened what we
are doing for this example.

Thanks again!

That actually worked fine and is exactly what we need. We must have
been doing something wrong before. Thanks!
