Примеры

In this example, each Stroke object in the provided Strokes collection is examined. If a Stroke object contains all of the extended properties in the provided ExtendedProperties collection, the Stroke is modified to display in a different color.

Private Sub HighlightLikeStrokes(ByVal ep As ExtendedProperties, ByVal theStrokes As Strokes)
    If ep.Count > 0 Then
        For Each theStroke As Stroke In theStrokes
            Dim containsCount As Integer = 0
            For k As Integer = 0 To ep.Count
                If theStroke.ExtendedProperties.Contains(ep(k)) Then
                    containsCount += 1
                End If
            Next
            ' If all the extended properties are there, color the stroke blue
            If containsCount = ep.Count Then
                theStroke.DrawingAttributes.Color = Color.PowderBlue
            End If
        Next
        mInkOverlay.AttachedControl.Invalidate()
    End If
End Sub

private void HighlightLikeStrokes(ExtendedProperties ep, Strokes theStrokes)
{
    if (ep.Count > 0)
    {
        foreach (Stroke theStroke in theStrokes)
        {
            int containsCount = 0;
            for (int k = 0; k < ep.Count; k++)
            {
                if (theStroke.ExtendedProperties.Contains(ep[k]))
                {
                    containsCount++;
                }
            }
            // If all the extended properties are there, color the stroke blue
            if (containsCount == ep.Count)
            {
                theStroke.DrawingAttributes.Color = Color.PowderBlue;
            }
        }
