Spellex SDK for ActiveX - Technical Support
Product: Spellex ActiveX
Problem: The contents of the window referenced by the TextControlHWnd property are not updated when the ShowContext property is set to True.
Solution: This behavior is by design. When ShowContext is True, the context window is the window that is updated during checking. Spellex ActiveX will update either the context window or the window referenced by the TextControlHWnd property, but not both. If you need to update both, you can catch Spellex ActiveX events and highlight and replace words as described in the Spellex ActiveX Programmer's Guide under "How to highlight misspelled words" and "How to update the checked document."
Alternatively, you can obtain the corrected text through the Text property when the spelling check is finished, and copy the text to the original control.
