屬性值
型別:System.Double
實際繪製在手寫板螢幕上,而且是使用者書寫所在之矩形的底端座標。
備註
繪製方塊的界限是視覺提示,可指定書寫的所在位置。使用者通常會在各行界限內書寫。繪製方塊是由 DrawnBoxTop、DrawnBoxLeft、DrawnBoxBottom 及 DrawnBoxRight 屬性指定。這些屬性僅供辨識器使用。設定這些屬性的動作本身並不會在顯示器上繪製視覺線索。您必須使用應用程式或控制項繪製視覺線索。
另一個矩形 (即書寫方塊) 是實際上會發生書寫的不可見的方塊。書寫方塊大於繪製方塊,當使用者在繪製方塊行外繪製筆墨時,可提供容錯邊界。書寫方塊是由 WritingBoxTop、WritingBoxLeft、WritingBoxBottom 和 WritingBoxRight 屬性指定。
如果您嘗試將 DrawnBoxBottom 屬性設定為小於 AnalysisRegion.MinXY 或大於 AnalysisRegion.MaxXY,這個屬性會擲回 ArgumentOutOfRangeException。

Dim guideBoxBottom As Double = 50
Dim guideBoxLeft As Double = 0
Dim guideBoxRight As Double = 600
Dim WRITINGBOXMARGIN As Integer = 10
' Find the midline of the guide box.
Dim midline As Double = (guideBoxBottom - guideBoxTop) / 2 + guideBoxTop
theGuide.Rows = 1
theGuide.Columns = 0
theGuide.Midline = midline
theGuide.WritingBoxLeft = guideBoxLeft - WRITINGBOXMARGIN
theGuide.WritingBoxTop = guideBoxTop - WRITINGBOXMARGIN
theGuide.WritingBoxRight = guideBoxRight + WRITINGBOXMARGIN
theGuide.WritingBoxBottom = guideBoxBottom + WRITINGBOXMARGIN
theGuide.DrawnBoxLeft = guideBoxLeft
