Module Name:
snpnode.h
Abstract:
Header for the CSnapinNode class.
This is our virtual base class for an MMC Snap-in node.
As this is a template class and is all implemented inline,
there is no SnapinNode.cpp for implementation.
Author:
Original: Michael A. Maguire
Modifications: RaphiR
Changes:
Specific MSMQ support:
Default images
Default columns
Support for Extension snapins
Add a CComponentData pointer
SetIcons method
Move m_pParentNode to CSnapinItem
zvib - Add RefreshSingleResultItem
Jun 10 1999 adik Change bitmap mask to white.
Jun 14 1999 roytal used UNREFERENCED_PARAMETER to fix build wrn
Jun 24 1999 adik Handle MMCN_COLUMNS_CHANGED
Jun 30 1999 adik More detailed DPF in CSnapinNode::Notify
// //
// Sep 22 1999 yossg welcome To Fax Server //
// Oct 11 1999 yossg replace DPF with fax's DebugPrintfEx //

CSnapinNode::Notify

STDMETHOD( Notify ) (
MMC_NOTIFY_TYPE event

, IComponentData * pComponentData
, IComponent * pComponent

Parameters
event
[in] Identifies an action taken by a user. IComponent::Notify and
IComponentData::Notify can receive the following notifications for a
specific node:
MMCN_ACTIVATE
MMCN_ADD_IMAGES
MMCN_BTN_CLICK
MMCN_CLICK
MMCN_CONTEXTMENU
MMCN_DBLCLICK
MMCN_DELETE
MMCN_EXPAND

MMCN_SELECT
MMCN_SHOW
MMCN_VIEW_CHANGE
MMCN_CONTEXTHELP
See CSnapinNode::OnActivate, OnAddImages, OnButtonClick, etc. for
a detailed explanation of each of these notify events
arg
Depends on the notification type.
param
Depends on the notification type.
Return Values
S_OK
Depends on the notification type.
E_UNEXPECTED
An unexpected error occurred.
Remarks
Our IComponentData and IComponent implementations were passed a LPDATAOBJECT
which corresponds to a node. This was converted to a pointer to
a node object. Below is the Notify method on this node object, were
the node object can deal with the Notify event itself.
Our implementation of Notify is a large switch statement which delegates the
task of dealing with virtual OnXxxxxx methods which can overridden in
derived classes. As all events are dealt with this way here, you shouldn't
need to implement a Notify method for any of your derived nodes.

CSnapinNode::OnViewChange
virtual HRESULT OnViewChange(
, LPARAM arg
, LPARAM param
, IComponentData * pComponentData
, IComponent * pComponent
, DATA_OBJECT_TYPES type
)
In our implementation, this method gets called when the MMCN_VIEW_CHANGE Notify
message is sent for this node.
MMC sends this message to the snap-in's IComponent implementation so it
can update all views when a change occurs. This node data object passed
to IConsole::UpdateAllViews.
Parameters
arg
[in] The data parameter passed to IConsole::UpdateAllViews.
param
[in] The hint parameter passed to IConsole::UpdateAllViews.
Return Values
Not used.
Remarks
This notification is generated when the snap-in (IComponent or
IComponentData) calls IConsole::UpdateAllViews.

virtual HRESULT OnColumnsChanged(

, LPARAM param
, IComponentData * pComponentData
, IComponent * pComponent
, DATA_OBJECT_TYPES type
)
In our implementation, this method gets called when the MMCN_COLUMNS_CHANGED Notify
message is sent for this node.
MMC sends this message to the snap-in's IComponent implementation so it
can decide if it can accept the column changes.
If snapin refuses to accept column changes then it is upto the snapin to display a message box
explaining the user why it is unable to do so.
Parameters
arg
[in] The data parameter passed to IConsole::UpdateAllViews.
param
[in] The hint parameter passed to IConsole::UpdateAllViews.
Return Values
S_OK,
A node can override this by returning E_UNEXPECTED that
discard user changes. In such a case display a message box
explaining the user why it is unable to do so.
Remarks
This notification is generated when the snap-in (IComponent or
IComponentData) calls IConsole::UpdateAllViews.
