MMCN_SELECT

[This is preliminary documentation and subject to change.]

Sent to the snap-in's IComponent::Notify or IExtendControlbar::ControlbarNotify when an item in either the scope pane or result view pane is selected.

Parameters

For IComponent::Notify:

lpDataObject

[in] Pointer to the data object of the currently selected scope pane item.

arg

BOOL bSelec = (BOOL) HIWORD(arg);

bScope

TRUE if an item in the scope pane is selected.

FALSE if an item in the result view pane is selected.

bSelect

TRUE if the item is selected.

FALSE if the item is deselected.

param

This parameter is ignored.

For IExtendControlbar::ControlbarNotify:

arg

BOOL bScope = (BOOL) LOWORD(arg);

BOOL bSelect = (BOOL) HIWORD(arg);

bScope:

TRUE if an item in the scope pane is selected.

FALSE if an item in the result pane is selected.

bSelect:

TRUE if the item is selected.

FALSE if the item is deselected.

param

LPDATAOBJECT pDataobject = (LPDATAOBJECT)param;

pDataobject data object of the item being selected or deselected.

Remarks

When an IComponent::Notify method receives the MMCN_SELECT notification it should update the standard verbs.

When an IExtendControlbar::ControlbarNotify method receives the MMCN_SELECT notification it should update the custom toolbars. On select, it should detach unused toolbars and attach new ones as needed. On deselect, to minimize flashing, it should not detach toolbars; it is best to disable them, but doing nothing on deselect is also acceptable.

Snap-ins should have the ability to create and attach toolbars when they receive a selection notification, regardless of whether the item is in the scope pane or result pane.
