EXTENSION_SNAPIN_DATACLASS
Adds a data member to the snap-in extension data class for an ISnapInItemImpl-derived class.
EXTENSION_SNAPIN_DATACLASS(
dataClass
)
Parameters
- dataClass
[in] The data class of the snap-in extension.
Remarks
This class should also be entered into a snap-in extension data class map. Start your snap-in extension data class map with the BEGIN_EXTENSION_SNAPIN_NODEINFO_MAP macro, add entries for each of your snap-in extension data types with the EXTENSION_SNAPIN_NODEINFO_ENTRY macro, and complete the map with the END_EXTENSION_SNAPIN_NODEINFO_MAP macro.
Example
class CMyExtSnapinExtData :
public CSnapInItemImpl<CMyExtSnapinExtData>,
public CMySnapinBase
{
public:
CMyExtSnapinExtData() {}
};
class CMyExtSnapin :
public CComObjectRoot,
public CSnapInObjectRoot<1, CMyExtSnapin>,
public IComponentDataImpl<CMyExtSnapin, CMyExtSnapin>
{
public:
CMyExtSnapin() {}
BEGIN_COM_MAP(CMyExtSnapin)
END_COM_MAP()
EXTENSION_SNAPIN_DATACLASS(CMyExtSnapinExtData)
BEGIN_EXTENSION_SNAPIN_NODEINFO_MAP(CMyExtSnapin)
EXTENSION_SNAPIN_NODEINFO_ENTRY(CMyExtSnapinExtData)
END_EXTENSION_SNAPIN_NODEINFO_MAP()
};
