Follow the instructions in $ACE_ROOT/ACE-INSTALL.html for building + ACE with Visual C++. Do a Batch Build of ACE, and make sure that you build + the target "ACE DLL - Win32 MFC Debug". + + - We must call ACE::init() and ACE::fini() in the right places + otherwise we will get strange crashes and memory leaks + when invoking ACE_Log_Msg::instance(). + A good place to invoke these methods is in the method which overrides + CWinApp::InitInstance(). + In this example, we invoke these methods in CLog_Msg_MFCApp::InitInstance(). + + - We must set the ACE_Log_Msg singleton to use our callback with: + ACE_Log_Msg::instance()->msg_callback( &m_mfc_logger ); + ACE_Log_Msg::instance()->set_flags( ACE_Log_Msg::MSG_CALLBACK ); + + This is also done in CLog_Msg_MFCApp::InitInstance(). + + +THANKS +====== +Thanks to the following people who provided assistance on the ACE +mailing list: +Chris Hafey <chafey@stentor.com> +Don Hinton <dhinton@ieee.org> + |
