public EventThrottler(
	ISynchronizeInvoke synchronizingObject,
	int interval,
	IEqualityComparer<TEventArgs> eventArgsComparer
)

Public Sub New ( 
	synchronizingObject As ISynchronizeInvoke,
	interval As Integer,
	eventArgsComparer As IEqualityComparer(Of TEventArgs)
)

Parameters

synchronizingObject

Type: System.ComponentModelISynchronizeInvoke
The synchronizing object. If null, the EventThrottled event might be raised by a different thread, as the System timer used for queue processing is using a threadpool in that case. If the handler has to run on the same thread as the UI, specify a UI object as synchronizingObject, e.g. a form object or control object on which this throttler is used.

interval

Type: SystemInt32
The interval, in milliseconds. If smaller than 100, it's set to 500

eventArgsComparer

Type: System.Collections.GenericIEqualityComparerTEventArgs
The event args comparer. Can be null, in which the default equality comparer is used.
