Public Enum ADVF
For data advisory connections, assures accessibility to data.
For data advisory connections (DAdvise(FORMATETC, ADVF, IAdviseSink, Int32) or Advise(Object, Int32)), this flag requests the data object not to send data when it calls OnDataChange(FORMATETC, STGMEDIUM).
Requests that the object make only one change notification or cache update before deleting the connection.
Requests that the object not wait for the data or view to change before making an initial call to OnDataChange(FORMATETC, STGMEDIUM) (for data or view advisory connections) or updating the cache (for cache connections).
This value is used by DLL object applications and object handlers that perform the drawing of their objects.
Synonym for ADVFCACHE_FORCEBUILTIN, which is used more often.
For cache connections, this flag updates the cached representation only when the object containing the cache is saved.
