MMCN_PRELOAD message
The MMCN_PRELOAD notification is introduced in MMC 1.1.
The MMCN_PRELOAD notification message is sent to the snap-in's IComponentData implementation if the snap-in returned TRUE when MMC called IDataObject::GetDataHere with the CCF_SNAPIN_PRELOADS format.
Parameters
-
lpDataObject [in]
-
A pointer to the data object of the static node of the snap-in being preloaded.
-
arg [in]
-
HSCOPEITEM of the static node of the snap-in being preloaded.
-
param
-
Not used.
Return value
-
S_OK
-
The snap-in successfully handled the notification.
-
S_FALSE
-
The snap-in does not handle the notification. MMC then performs a default operation for the notification.
Remarks
When a console file is saved, MMC calls IDataObject::GetDataHere on each loaded snap-in using the CCF_SNAPIN_PRELOADS clipboard format. If the snap-in handles the CCF_SNAPIN_PRELOADS clipboard format and returns TRUE, MMC calls the IComponentData::Notify method of the snap-in with the MMCN_PRELOAD notification when the snap-in's parent is first selected. If a preload is not requested, MMC does not load a snap-in until the snap-in's static node is selected. Until then MMC displays a cached icon and name for the snap-in's static node.
The preloaded snap-in can handle this notification by performing any actions required before it displays its static node or its child items (for example, a dynamic name for an item based on context such as a file name or computer name).
