Module control 

Form control support for Excel worksheets.

Excel uses legacy VML (Vector Markup Language) drawing parts for form controls such as buttons, check boxes, option buttons, spin buttons, scroll bars, group boxes, and labels. This module generates the VML markup needed to add form controls and parses existing VML to read them back.
