MMCPropertyChangeNotify function (mmc.h)
The MMCPropertyChangeNotify function enables a snap-in property sheet to notify its IComponent or IComponentData interface that an item's properties have changed.
Property sheets run in a different thread than their IComponent and IComponentData server; therefore, if param is a COM interface pointer, it must be marshaled. Asynchronously calling this function notifies the IComponent or the IComponentData associated with the property page whose properties have changed.
Syntax
HRESULT MMCPropertyChangeNotify(
[in] LONG_PTR lNotifyHandle,
[in] LPARAM param
);
Parameters
[in] lNotifyHandle
A value that specifies the handle used to route the notification message to the appropriate IComponent or IComponentData.
[in] param
User-defined. Can be used freely.
Return value
This callback function can return one of these values.
Remarks
This is the handle passed to IExtendPropertySheet2::CreatePropertyPages.
A call to MMCPropertyChangeNotify causes an MMCN_PROPERTY_CHANGE notification to be sent to the snap-in.
The param value that is passed to MMCPropertyChangeNotify is, in turn, forwarded to the snap-in as the param argument to MMCN_PROPERTY_CHANGE.
