COM 库的属性/方法描述

问题描述

如果您创建 COMClass，我注意到当您引用生成的 tlb 文件时，XML 摘要标记中的值不会显示在 VB6/VBA 的对象浏览器中.有没有办法显示这些值?

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 values show up?

推荐答案

不，12 年的 IntelliSense 发展阻止了它的工作.XML 文档注释会生成一个 IntelliSense 可以提取的 .xml 文件.在 VB6/A 中，文档存在于具有帮助字符串属性的类型库中.例如:

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...
};

从 [ComVisible] 类库中获取相同的内容需要 [Description] 属性.请注意this answer，了解它对属性的工作方式.

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.
