[AGENT++] Need help about Logging to file

[lsq]

Hi all,

I'm using Agent++ 3.5.12，build it to a dll,
In my MFC program，I want log to a file.

The codes I use are as below:

	strLogFile=".\\file.txt";
	pfile=fopen(strLogFile,"a");

	
#ifndef _NO_LOGGING
	((AgentLogImpl*) DefaultLog::log())->set_dest(pfile);
	DefaultLog::log()->set_filter(ERROR_LOG, 5);
	DefaultLog::log()->set_filter(WARNING_LOG, 5);
	DefaultLog::log()->set_filter(EVENT_LOG, 5);
	DefaultLog::log()->set_filter(INFO_LOG, 5);
	DefaultLog::log()->set_filter(DEBUG_LOG, 6);
#endif
.....

		LOG_BEGIN(EVENT_LOG | 1);
		LOG("main: SNMP listen port");
		LOG(port);
		LOG_END;

But I got a Access Violation at "LOG_END;"

When I trace into the dll, it stop at "AgentLog& AgentLogImpl::operator+=(const LogEntry* log)"
it was "fprintf(logfile, "%s\n", log->get_value())" where the violation happens

Is here someone can help me to solve the problem?
