   ByVal e As UserStateEventArgs _
)

'Usage
 
Dim instance As ComponentBase

protected virtual void OnUserState( 
   UserStateEventArgs e
)

protected: virtual void OnUserState( 
   UserStateEventArgs* e
)

protected:
virtual void OnUserState( 
   UserStateEventArgs^ e

Parameters

e: A UserStateEventArgs object that contains the user information.

If the Synchronizing property is set, this method invokes UserState asynchronously on the UI thread. If the Synchronizing property is null, this method invokes UserState on the executing thread.

OnUserState allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class, but marshaling is not provided.

Note to Inheritors: When overriding OnUserState in a derived class, be sure to call the base class OnUserState method, so that registered delegates receive the event.

See the SynchronizingObject property for information on updating UI controls in your event handler.
