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