Hi all, I am converting the pjsua application given in the pj-project as an MFC application. I am facing the following problem ?cannot convert from 'void (__thiscall Phone::* )(pjsua_acc_id)' to 'void (__cdecl *)(pjsua_acc_id)' There is no context in which this conversion is possible? Here is the my code. I am writing using Visual studio 2005 /*********** PhoneDlg.h************/ #include <pjsua-lib/pjsua.h> Phone:: public CDialog { ? void on_reg_state(pjsua_acc_id acc_id); ?. } /************ PhoneDlg.cpp ***********/ #include "PhoneDlg.h" void Phone:: on_reg_state(pjsua_acc_id acc_id) { pjsua_acc_info info; CString reg_status; pjsua_acc_get_info(acc_id,&info); reg_status=info.status_text.ptr; /** Now update the registration status on Phone?s main dialog edit control, m_userinfo is the edit control value variable on Phone?s main dialog ******/ m_userinfo=reg_status; // m_userinfo is the CString value variable for the edit-control box UpdateData(false); } BOOL Phone:: OnInitDialog() { ???????????????? pjsua_config cfg; //pjsua_config is a struct ?????????????? cfg.cb.on_reg_state = &Phone:: on_reg_state; --------------------------- ?????????????????. } if I declare the "on_reg_state" as a static function, the UpdateData(false) gives error as it cannot access the members of the class Phone. And if I dont call the "UpdateData(false)", the edit control box is not updated. If I declare the "on_reg_state" as a global function, then I can not update the status on the dialog. This problem is with other callback functions on_incoming_call, on_media_state as well. The Soft Phone is working perfect except this update problem.[?] I am badly stuck in this, please help ahong -------------- next part -------------- An HTML attachment was scrubbed...
