Remarks

The writing box provides a margin of error to users who write outside the drawn box. Use the DrawnBoxTop, DrawnBoxLeft, DrawnBoxBottom, and DrawnBoxRight properties to set the drawn box.

The WritingBoxBottom property throws an ArgumentOutOfRangeException if you try to set it to a value less that AnalysisRegion.MinXY or greater than AnalysisRegion.MaxXY.

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
theGuide.DrawnBoxTop = guideBoxTop
theGuide.DrawnBoxRight = guideBoxRight
theGuide.DrawnBoxBottom = guideBoxBottom

theGuide.Midline = midline;

theGuide.WritingBoxLeft = guideBoxLeft - WRITINGBOXMARGIN;
theGuide.WritingBoxTop = guideBoxTop - WRITINGBOXMARGIN;
theGuide.WritingBoxRight = guideBoxRight + WRITINGBOXMARGIN;
theGuide.WritingBoxBottom = guideBoxBottom + WRITINGBOXMARGIN;
