RecognizerContextRecognitionEventArgs.Text Property

Gets a string that contains the recognition result text with the highest confidence.

Definition

Visual Basic .NET Public ReadOnly Property Text As String

C# public string Text { get; }

Managed C++ public: __property String* get_Text();

Property Value

System.String. The recognition result text with the highest confidence.

This property is read-only. This property has no default value.

Examples

[C#]

This C# example is from a Form Leave Site , RecognitionEventForm, that performs background recognition by calling the BackgroundRecognize method of the RecognizerContext object, theRecognizerContext, as each stroke is collected and displays the result in the ListBox control, theListBox, as they are generated.

A time stamp is used in the call to the BackgroundRecognize method. The event handler for the Recognition event, Recognition_Event, retrieves the time stamp by checking the CustomData property of the event arguments.

private Microsoft.Ink.InkCollector theInkCollector;
private Microsoft.Ink.Strokes theStrokes;
private Microsoft.Ink.RecognizerContext theRecognizerContext;

private System.Windows.Forms.ListBox theListBox;

// Event handler for the form's Load event
private void RecognitionEventForm_Load(object sender, System.EventArgs e)
{
    // Create a new ink collector and recognizer context.
    this.theInkCollector = new Microsoft.Ink.InkCollector(this.Handle);
    this.theRecognizerContext = new Microsoft.Ink.RecognizerContext();

    // Initialize the RecognizerContext object's strokes.
    this.theStrokes = this.theInkCollector.Ink.Strokes;
    this.theRecognizerContext.Strokes = this.theStrokes;

    // Attach event handlers.

    this.theRecognizerContext.Recognition +=

    InkCollectorStrokeEventArgs e)
{
    // When a new stroke is collected,
    // add it to the recognizer's strokes collection.

    // Tell the context to recognize its strokes.
    // Add a time stamp as custom data for the Recognition event.
    DateTime timeStamp = DateTime.Now;
    this.theRecognizerContext.BackgroundRecognize(timeStamp);
}

// Recognition Event Handler
private void Recognition_Event(
    object sender,
    RecognizerContextRecognitionEventArgs e)
{
    // Update the list box
    this.theListBox.Items.Clear();
    this.theListBox.Items.Add("The recognition status is: " + e.RecognitionStatus.ToString());
    this.theListBox.Items.Add("The time stamp is: " + ((DateTime)e.CustomData).ToString());
    this.theListBox.Items.Add("The recogniton text is: " + e.Text);
}

// Event handler for the form's closed event
private void RecognitionEventForm_Closed(object sender, System.EventArgs e)
{
    this.theInkCollector.Dispose();
    this.theInkCollector = null;
    this.theRecognizerContext.Dispose();
    this.theRecognizerContext = null;
