ComponentData.cpp
|
|
|
|
Abstract:
|
|
|
|
The CComponentData class implements several interfaces which MMC uses:
|
|
|
|
The IComponentData interface is basically how MMC talks to the snap-in
|
|
to get it to implement the left-hand-side "scope" pane.
|
|
|
|
The IExtendPropertySheet interface is how the snap-in adds property sheets
|
|
for any of the items a user might click on.
|
|
|
|
The IExtendContextMenu interface what we do to add custom entries
|
|
to the menu which appears when a user right-clicks on a node.
|
|
|
|
The IExtendControlBar interface allows us to support a custom
|
|
iconic toolbar.
|
|
|
|
See ComponentData.cpp for implementation.
|
|
|
|
Note:
|
|
|
|
Much of the functionality of this class is implemented in atlsnap.h
|
|
by IComponentDataImpl. We are mostly overriding here.

// This is a big hack to work around a atlsnap.h bug: Atlsnap.h
|
|
// can't support extending multiple nodes. So we basically just

// copied EXTENSION_SNAPIN_NODEINFO_ENTRY() here. We need to change

// this after the atlsnap.h fix -- MAM: 08-06-98 -- yeah right

|
//
|
|
// The following statements are copied from atlsnap.h and then changed
|
|
// to support multiple extending node
|
|
//
|
|
// IsSupportedGUID will also set the m_enumExtendedSnapin flag in side m_##dataClass object
|
|
// which, in our case, is CMachineNode
