	None	Specifies that no confirmation is applied. The InkAnalyzer is free to change a context node or any of its descendants as needed.
	NodeTypeAndProperties	Specifies that the InkAnalyzer cannot change type or any properties of the specified context node.
	TopBoundary	Specifies that the InkAnalyzer will not perform operations, including adding ink or merging with other ContextNodes, that cause the TopBoundary to move beyond the current top boundary. For example:

Заметки

You can use NodeTypeAndProperties only for ContextNode objects of type InkWord and InkDrawing. Otherwise, an InvalidOperationException is thrown.

Примеры

The following example is an event handler for the MouseUp event on a Panel, theNotesPanel, which is collecting ink through an InkCollector, theInkCollector. The application has a Boolean, confirmMode, which is set by a MenuItem, confirmMenuItem. In "confirm" mode, the user clicks a word to confirm it (or to turn off confirmation if the node is already confirmed). The example converts the MouseUp mouse up event into ink coordinates, and uses HitTest and FindNodesOfType to find the appropriate nodes. After the nodes are found, Confirm is called to toggle the confirmation. Finally, the application is taken out of "confirm" mode.

Private Sub theNotesPanel_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles theNotesPanel.MouseUp
    If Me.confirmMode = True Then
        ' Translate coordinates into ink dimensions
        Dim hitPoint As New Point(e.X, e.Y)
        Dim panelGraphics As Graphics = Me.theNotesPanel.CreateGraphics()
        Me.theInkCollector.Renderer.PixelToInkSpace(panelGraphics, hitPoint)
        panelGraphics.Dispose()

        ' Find the strokes that the user selected
        Dim selectedStrokes As Strokes = Me.theInkCollector.Ink.HitTest(hitPoint, 10)

        ' Find the ink word nodes that correspond to those strokes
        Dim selectedNodes As ContextNodeCollection = _
            Me.theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, _
            selectedStrokes)

        ' Toggle the confirmation type on these nodes
        Dim selectedNode As ContextNode
        For Each selectedNode In selectedNodes
            If selectedNode.IsConfirmed(ConfirmationType.NodeTypeAndProperties) = True Then
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.None)
            Else
                selectedNode.Confirm(Microsoft.Ink.ConfirmationType.NodeTypeAndProperties)
            End If
        Next selectedNode

        Me.confirmMode = False
        Me.ConfirmMenuItem.Checked = False
