When I respond to SC_MOD_INSERTCHECK with an empty SCI_CHANGEINSERTION
(thanks for this addition to Scintilla, BTW!) to veto the input, it works
correctly when there is no selection. However, when there's selected text,
the selection gets deleted instead of vetoing the input. How can I get it
to work correctly for selected text as well?


Best regards,

Jari Williamsson

I've also been looking at this recently, as I am implementing a patch to
allow vetoing of any kind of modification to the document.

What you describe is a limitation of the code as it currently stands. I
hope to submit a patch to scintilla-interest either by the end of this week
or early next week with the new modification veto code. I would be
extremely grateful if you would provide feedback on it and let me know of
any problems.
