enum System.Runtime.InteropServices.ComTypes.ADVF

Assembly: System.Runtime.InteropServices

Specifies the requested behavior when setting up an advise sink or a caching connection with an object.

Values

ADVF_NODATA

For data advisory connections ( <see cref="M:System.Runtime.InteropServices.ComTypes.IDataObject.DAdvise(System.Runtime.InteropServices.ComTypes.FORMATETC@,System.Runtime.InteropServices.ComTypes.ADVF,System.Runtime.InteropServices.ComTypes.IAdviseSink,System.Int32@)" /> or <see cref="M:System.Runtime.InteropServices.ComTypes.IConnectionPoint.Advise(System.Object,System.Int32@)" /> ), this flag requests the data object not to send data when it calls <see cref="M:System.Runtime.InteropServices.ComTypes.IAdviseSink.OnDataChange(System.Runtime.InteropServices.ComTypes.FORMATETC@,System.Runtime.InteropServices.ComTypes.STGMEDIUM@)" /> .

ADVF_PRIMEFIRST

Requests that the object not wait for the data or view to change before making an initial call to <see cref="M:System.Runtime.InteropServices.ComTypes.IAdviseSink.OnDataChange(System.Runtime.InteropServices.ComTypes.FORMATETC@,System.Runtime.InteropServices.ComTypes.STGMEDIUM@)" /> (for data or view advisory connections) or updating the cache (for cache connections).

ADVF_ONLYONCE

Requests that the object make only one change notification or cache update before deleting the connection.

ADVFCACHE_NOHANDLER

Synonym for <see cref="F:System.Runtime.InteropServices.ComTypes.ADVF.ADVFCACHE_FORCEBUILTIN" /> , which is used more often.

ADVFCACHE_FORCEBUILTIN

This value is used by DLL object applications and object handlers that perform the drawing of their objects.

ADVFCACHE_ONSAVE

For cache connections, this flag updates the cached representation only when the object containing the cache is saved.

ADVF_DATAONSTOP

For data advisory connections, assures accessibility to data.
