RichTextEdit controls
The SelectedTextLength property specifies the length of text you want to highlight in a selected text string.
Typically you use this property to obtain the length of a misspelled word that is flagged after passing the selected text string to a supported ActiveX spell checking control.
See the chapter on implementing rich text in Application Techniques for more information about spell checking text in RichTextEdit controls.
The SelectedTextLength property cannot be set in a design-time painter.
The SelectedTextLength property takes a long value. The following code in a MixedCaseWord or ReplaceWord event for the Wintertree Software WSpell ActiveX control causes a word flagged by the control to be highlighted for its entire length, beginning with the word’s offset position in the text string that you are spell checking:
string strword
strword = wspell.object.MisspelledWord
rte_1.SelectedStartPos = wspell.object.WordOffset
rte_1.SelectedTextLength = Len(strword)
