> Another question is why i can't open application.uidesign, > symbian_ua_guiContainer.uidesign and > symbian_ua_guiSettingItemList.uidesign through carbide.c++ v1.3(Express Ed) 1. Express Edition doesn't support GUI design and On device debuging. see http://www.forum.nokia.com/main/resources/tools_and_sdks/carbide_cpp/ 2. If you have problem loading udesign file under DEV, PRO or OEM edition please make another separate import \pjsip-apps\src\symbian_ua_gui\group\bld.inf, this may brake directory location structure, but you can load .uidesign file for editing. Hope this will help. atik
