I have a managed assembly that gets called via COM Interop. Like a VBScript client, a Perl client, and so on.
The classes are decorated with
[ClassInterface(ClassInterfaceType.AutoDual)]
[GuidAttribute("ebc25cf6-9120-4283-b972-0e5520d0000E")]
[ComVisible(true)]
Then of course I do the regasm thing, and all the methods work just fine.
But there are also enum types in the assembly. I'd like to use symbolic names COM applications, for the enum values.
How do I expose the enums via COM interop? Do I just need to add these attributes?
[GuidAttribute("ebc25cf6-9120-4283-b972-0e5520d0000E")]
[ComVisible(true)]
And then, how do I reference those symbolic names in VBScript? I don't see the enum types in OleView. (Should I?) I see all the other types in OleView.
VBScript and other late-bound clients use IDispatch to call methods on objects. As such, these languages don't have access to type information in the typelib -- they just create an object from a GUID, get an IDispatch pointer back, and start calling methods by name.
I'm unsure of the COM interop part of the question, but even if the enums did show in OleView, you wouldn't be able to use them directly.
However, if you are able to publish the enums in the typelib, I wrote a tool eons ago that can generate a script file (vbs or js) containing all the enums from a typelib as constants.
