Property/Method Descriptions for COM Libraries

If you create a COMClass, I've noticed that the values in the XML Summary tag do not show in the object browser of VB6/VBA when you reference the resulting tlb file. Is there a way to have these valu开发者_JAVA百科es show up?


No, 12 years of IntelliSense evolution prevents this from working. The XML documentation comments generates an .xml file that IntelliSense can pick up.

In VB6/A, documentation is present in the type library with the helpstring attribute. For example:

[
  odl,
  uuid(2334D2B1-713E-11CF-8AE5-00AA00C00905),
  hidden,
  dual,
  nonextensible,
  oleautomation
]
interface IVBDataObject : IDispatch {
    [id(0x00000001), helpstring("Clears all data and formats in a DataObject object."), helpcontext(0x00033693)]
    HRESULT Clear();
    // etc...
};

Getting the same from your [ComVisible] class library requires the [Description] attribute. Note this answer for a quirk about the way it works for properties.
