I would like to create a control to do something like this:
accept a numeric value (>0 and <=3899) in the textbox, convert it to a
Roman Numeral and display it in a label. Write functions called from
the Leave event of the textbox to validate the entry in the textbox and
convert it to Roman.
The entry of an invalid value in the textbox should result in the entry
going away, the textbox becoming yellow and getting focus. Valid
entries should turn the textbox green and the control itself medium
seagreen and display the Roman Numeral in the label.
anyone have any ideas how this would be done?
