The code was designed to build a dll to log trace statements to a text file
at customer sites. At the end of the day the customers emails me the text log.
To use the LogTrace.dll in your project add LogTrace.lib to the Object/Library modules in your linker settings and include the header Trace.h to your project.
In your InitInstance() call
TraceReadINI();After that you can call Trace() like printf or TRACE
Trace("This is my string value [%s]\n", m_strMessage); //Works like printf or TRACE
|TraceStart(char *pszPathName = NULL)||A call to TraceStart() will start tracing until end of execution or TraceStop(). The log will default to the directory of the application that called it. You can over ride the default behavior by passing in your own path, file name and file name extension. The existing log is always numerically archived. If more than one instance of an application is executing, then susequent applications will have the post fix 'HMODULE' in the log entries.|
|TraceReadINI()||Reads control values from the applications ini file.
|Trace(const char *pszFormat, ...)||Works just like TRACE() or printf(). The first parameter can be any length, the sum of the additional parameters is limited to 1024 characters.|
|TraceSuspend(bool bTrueToSuspend)||When true logging is suspended until set back to false.
Default is false
|TraceStop()||The current log is closed. To continue logging, explicitly call TraceStart(). In the event of multiple programs writing to the same log, the log will not be closed. The next call to TraceStart() will append to the existing log.|
|TraceClockCapture(char* pszComment = NULL)||Captures the current clock value.|
|TraceClockDuration (char* pszComment = NULL)||Writes the number of seconds passed since the last TraceClockCapture().|
|TraceFlush(bool bForceFlush)||You can turn it off to increase performance, but if the
application fails you may not get the last several dozen statements logged written to the
Default is true.
|TraceWithTime(bool bValue)||Causes the Trace() statement to output the time of each
trace statement. The year value is not output.
Default is true.
