Answer 1

When I set ExportToFile() function's last parameter to kFullUI ,
I get one Export JPEG window and
then error :-
"exind1.rtf" is already open by "^2".
You don't have permission to change the file.
After showing this message
one progress bar is shown and after that SVG options window is shown.
then one progress bar is shown and then one window of Adobe Indesign Tagged Text Options is displayed . When I click on Okof this window.
Rtf file is created without containing ant data.
Please give some solution for exporting indesign document to RTF format.
