MMCN_SNAPINHELP message
The MMCN_SNAPINHELP notification message is sent to the snap-in's IComponent implementation when the user requests help about the snap-in.
MMCN_SNAPINHELP is only sent to snap-ins that do not support HTML Help by implementing the ISnapinHelp2 interface.
Be aware that snap-ins that provide Help should implement ISnapinHelp2.
If a snap-in does not support HTML Help (ISnapinHelp2), when that snap-in's scope or result item is selected, MMC places a special menu item for it under the console's Help menu. The item is named "Help on <snap-in name>". If the user clicks this menu item, MMC sends the MMCN_SNAPINHELP notification to the snap-in. The snap-in should respond by that displays whatever Help information it has.
