Sorry, these forums aren't for Delphi, as it were. Delphi is an automotive company, as opposed to Borland Delphi. You might want to check the
product page for SynEdit. Apparently, there's some example code for using SynEdit components at
this website (about half way down the page).
Sorry for having to disappoint you. Maybe someone else on these forums may have the knowledge to help you, but the chances aren't as good as if you were to ask your question on a dedicated Delphi forum.
