since you already create a separate thread for the editing - just fire it off, and send the main app a msg - like here: desktop/source/app/officeipcthread.cxx:289 (you'll probably replace STATIC_LINK with LINK, DECL_STATIC_LINK with DECL_LINK, and IMPL_STATIC_LINK_NOINSTANCE with IMPL_LINK) PostUserEvent adds an event into the main app msg queue, which then gets processed like any other input (mouse, keyboard) in the LibO mainloop. Also: just using osl_executeProcess() avoids idly spinning until the external app is finished. Your thread just blocks then. HTH, -- Thorsten
