Заметки

When you create a ContextNodeCreatedEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

Примеры

The following example defines a method, AddContextNode, that handles the ContextNodeCreated event. The event information is passed to the document model object, theDocumentModel.

This example does not provide the definition of the document model or demonstrate how it processes the information passed to it.

'/ <summary>
'/ Handles the InkAnalyzer.ContextNodeCreated event.
'/ </summary>
'/ <param name="sender">The source of the event.</param>
'/ <param name="e">The event data.</param>
'/ <remarks>
'/ Note: when this event is fired, the ContextNode has not been populated
'/ with extended and other properties. Handle the ContextNodePropertiesUpdated
'/ event to populate the corresponding ContextNode in the document model.
'/ </remarks>
Private Sub AddContextNode( _
    ByVal sender As Object, _
    ByVal e As Microsoft.Ink.ContextNodeCreatedEventArgs)

    ' Do not add unclassified ink nodes to the document model.
    If Microsoft.Ink.ContextNodeType.UnclassifiedInk _
        <> e.NodeCreated.Type Then

        Me.theDocumentModel.AddNode(e.NodeCreated)
    End If

End Sub 'AddContextNode

        private void AddContextNode(

        {

            if (Microsoft.Ink.ContextNodeType.UnclassifiedInk
                != e.NodeCreated.Type)
            {
                this.theDocumentModel.AddNode(e.NodeCreated);
