Remarks
COM Signature
From context.idl:
HRESULT IVsUserContext::AddAttribute(
[in] VSUSERCONTEXTATTRIBUTEUSAGE usage,
[in] LPCOLESTR szName, [in] LPCOLESTR szValue
);
The IVsUserContext.AddAttribute method adds an attribute, lookup keyword, or F1 keyword to the context or subcontext bag, without overriding the values already present. Keywords are used by the Dynamic Help window to complete a lookup in the information provider, which returns a list of topics related to the keyword. The Dynamic Help window then uses the attributes in the active context to filter the list returned by the information provider. Any topics with attributes that do not match those in the active context are filtered away and are not shown in the Dynamic Help window.
To remove one or several attributes, lookup keywords, or F1 keywords from the context bag, use the RemoveAttribute method. Use the RemoveAttributeIncludeChildren method to additionally remove attributes or keywords from the associated subcontext bag or bags.
