' Clear the analyzer's cache for each stroke that is moving.
Dim theStroke As Microsoft.Ink.Stroke
For Each theStroke In Me.selectedStrokes
    Me.theInkAnalyzer.ClearStrokeData(theStroke)
Next theStroke

// Update the analyzer's dirty region to include the original
// bounding box of the strokes that are moving.
this.theInkAnalyzer.DirtyRegion.Union(
    this.selectedStrokes.GetBoundingBox());

// Clear the analyzer's cache for each stroke that is moving.
foreach (Microsoft.Ink.Stroke theStroke in this.selectedStrokes)
{
    this.theInkAnalyzer.ClearStrokeData(theStroke);
