Using an ActiveX spell checking control

ActiveX controls
can be used to spell check text in a RichTextEdit control. The supported
ActiveX spell checking controls include VSSpell from ComponentOne
and WSpell from Wintertree Software.

You can use the SelectedStartPos and SelectedTextLength properties
of the RichTextEdit control to highlight the current position of
a misspelled word in a text string that you are parsing with a supported
ActiveX spell checking control. The following procedure uses an
ActiveX control to spell check the entire text of the current band
of a RichTextEdit control.
