示例

下面的示例定义 AddContextNode 方法，用以处理 ContextNodeCreated 事件。事件信息将传递给文档模型对象 theDocumentModel。

此示例不提供文档模型的定义，也不演示文档模型如何处理传入的信息。

'/ <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

        /// <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 void AddContextNode(
            object sender, Microsoft.Ink.ContextNodeCreatedEventArgs e)
        {
            // Do not add unclassified ink nodes to the document model.
            if (Microsoft.Ink.ContextNodeType.UnclassifiedInk
                != e.NodeCreated.Type)
            {
                this.theDocumentModel.AddNode(e.NodeCreated);
            }
        }
