Parameters

active

TRUE (non-zero) to activate the subscription. FALSE (0) to deactivate the subscription. If the client deactivates the subscription, then the server will no longer send event notifications to the client based on that subscription, and has no responsibility to buffer or maintain the event notifications. Thus event notifications may be lost. Even if the subscription is inactive, the Refresh method will still function. In effect, this allows a client to obtain current condition states from time to time (by invoking Refresh) without the need to process event notifications in “real time”.

activeDefined

Must be TRUE for the 'active' property argument to be processed.

_bufferTime

bufferTimeDefined

Must be TRUE for the 'bufferTime' property argument to be processed.

_maxSize

maxSizeDefined

Must be TRUE for the 'maxSize' property argument to be processed.

_clientSubscription

revisedBufferTime

The buffer time that the server is actually providing, which may differ from bufferTime.

revisedMaxSize

The maximum number of events that the server will actually be sending in a single OnEvent callback, which may differ from dwMaxSize.

Target Platforms: Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows 7, Windows Server 2008 family
