The MMCN_FILTER_CHANGE notification is introduced in MMC 1.2.
The MMCN_FILTER_CHANGE notification message is sent to the snap-in's IComponent implementation when the filter value for a filtered result view column has been changed.
MMC calls IComponent::Notify with the MMCN_FILTER_CHANGE notification as the event parameter when filtering has been enabled or disabled, or when the filter value of a particular column has changed.
Parameters
-
lpDataObject [in]
-
Not used (NULL).
-
arg [in]
-
Filter change code (see MMC_FILTER_CHANGE_CODE enumeration).
-
param [in]
-
Column number of changed value, if change code is MFCC_VALUE_CHANGE.
Return value
-
S_OK
-
The snap-in successfully handled the notification.
-
S_FALSE
-
The snap-in does not handle the notification.
Remarks
The snap-in receives an MMCN_FILTER_CHANGE notification with the arg parameter set to MFCC_ENABLE when the user clicks the Filtered menu item or the snap-in programmatically sets the view mode to filtered view by setting the MMC_VIEW_OPTIONS_FILTERED option in the IComponent::GetResultViewType method.
The snap-in receives an MMCN_FILTER_CHANGE notification with the arg parameter set to MFCC_DISABLE when the user or the snap-in turns off filtering.
