Dear ADAM,
 Finally I add a Checkbox on the toolbar of the editor.
 How can I test if the box is checked:
 give me the code and their location to test; if the checkbox is checked,
 then an HTML page will be displayed in GetHtmlResult
. I tried several methods and I searched the net but I did
come to nothing because "if (isset ($ _POST [name_checkbox]" does nothing .
You are the only one who can give me the code because
you know all the code editor.
please i wait your answer.thanks a lot.
