'Usage
Dim instance As AnalysisStatus
Dim value As AnalysisRegion

value = instance.AppliedChangesRegion

public AnalysisRegion AppliedChangesRegion { get; }

public function get AppliedChangesRegion () : AnalysisRegion

Not applicable.

Property Value

The AnalysisRegion of the document where changes were updated.

Remarks

AppliedChangesRegion is used when the application must locate the area that changed. For example, the application might draw a special tag to click for the user to modify the analysis results.

Example

The following example is a ResultsUpdated event handler that is called when BackgroundAnalyze completes analysis. In the event handler, a Rectangle that represents the AppliedChangesRegion is drawn on an InkCanvas, theInkCanvas.

Sub theInkAnalyzer_ResultsUpdated(ByVal sender As Object, _
                                  ByVal e As ResultsUpdatedEventArgs)

    Dim status As AnalysisStatus = e.Status

    ' Draw a rectangle around the changed region.
    If status.Successful Then

        Dim bounds As Rect = status.AppliedChangesRegion.GetBounds()
        Dim box As Rectangle = New Rectangle()

        box.Width = bounds.Width
        box.Height = bounds.Height
        InkCanvas.SetTop(box, bounds.Top)
        InkCanvas.SetLeft(box, bounds.Left)

        box.Stroke = Brushes.Black
        theInkCanvas.Children.Add(box)
    End If

End Sub 'theInkAnalyzer_ResultsUpdated

void theInkAnalyzer_ResultsUpdated(object sender, ResultsUpdatedEventArgs e)
{
    AnalysisStatus status = e.Status;

    // Draw a rectangle around the changed region.
    if (status.Successful)
    {
        Rect bounds = status.AppliedChangesRegion.GetBounds();
        Rectangle box = new Rectangle();

        box.Width = bounds.Width;
        box.Height = bounds.Height;
        InkCanvas.SetTop(box, bounds.Top);
        InkCanvas.SetLeft(box, bounds.Left);
        
        box.Stroke = Brushes.Black;
        theInkCanvas.Children.Add(box);
    }

}
