Returns a human-readable string typefor the ContextNodeBase object.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public Overrides Function ToString As String
'Usage
Dim instance As ContextNodeBase 
Dim returnValue As String 

returnValue = instance.ToString()

public override string ToString()

Return Value

Type: System.String
A human-readable string type for the ContextNodeBase object.

Remarks

For example, if the Type is InkWord, this method returns a value of "InkWordNode".

Examples

This example is a method that recursively traverses a tree of ContextNodeBase objects. It uses the SubNodes property and populates a System.Windows.Forms.TreeView by adding TreeNode objects. It then sets their Text property to ToString, adding the recognized string or shape name if appropriate.

Private Sub WalkTree(ByVal parentContextNode As ContextNodeBase, ByVal parentTreeNode As TreeNode)

    Dim cNode As ContextNodeBase

    For Each cNode In parentContextNode.SubNodes

        Dim newTNode As New TreeNode(cNode.ToString())

        If cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord AndAlso _
           cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then

            newTNode.Text = newTNode.Text + _
                ": " + CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), _
                String)

        ElseIf cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing AndAlso _
               cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName) Then 

            Dim shapeName As String = CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName), _
                String)

            If shapeName <> "" Then
                newTNode.Text = newTNode.Text + ": " + shapeName
            End If 

        End If

        WalkTree(cNode, newTNode)
        parentTreeNode.Nodes.Add(newTNode)

        ' Add the context node as a tag of the tree node
        newTNode.Tag = cNode
    Next cNode

End Sub 'WalkTree

private void WalkTree(
    System.Windows.Ink.AnalysisCore.ContextNodeBase parentContextNode, TreeNode parentTreeNode)
{
    foreach (ContextNodeBase cNode in parentContextNode.SubNodes)
    {
        TreeNode newTNode = new TreeNode(cNode.ToString());
        if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord) &&
             cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString))
        {
            // Get the recognized string
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString);
        }
        else if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing) &&
                  cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName))
        {
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName);
        }
        WalkTree(cNode, newTNode);
        parentTreeNode.Nodes.Add(newTNode);

        // Add the context node as a tag of the tree node
        newTNode.Tag = cNode;
    }
}
