.NET Forum / Languages / C# / November 2006programmatically export the event log
Is there some way to export an event log to a .evt file? I ask because what we're trying to set up is a really easy way for a user to email the contents of our event log back to us in the event of some problem. Emailing isn't a big deal, the SmtpClient class is a breeze, and working with the EventLog class hasn't been a problem up to now. However, I can't find any functionality that exports logs. If I was in a particularly masochistic mood, I could always read the entries in the log one at a time and build a CSV file, but firstly, importing a CSV file into the event log viewer doesn't seem to work, and secondly, there's no reason I should have to do that much work to get something like this. Anybody have an answer? Lee Crabtree Hello Lee, why not to mail the copy of .evt file? LC> Is there some way to export an event log to a .evt file?

The BackupLogFile function consistently gives me an "Access Denied" exception, and the Copy function gives me a .evt file that I can't open in the Windows Event Viewer. Manually copying the actual log file gives me a file that also doesn't open in the Event Viewer. However, if I go into the Event Viewer and save a log file through the context menu, I can open the resulting log file just fine. What on EARTH is going on here?

Using "BackupEventLog" in WMI you'll need to enable the 'required' privilege by setting the EnablePrivileges to true. Say that eventLog refers to your eventlog ManagementObject instance, then you'll have to enable the required secuity privilege (in this case - SeBackupPrivilege) like this: eventLog.Scope.Options.EnablePrivileges=true; Willy. > Is there some way to export an event log to a .evt file?

What about grabbing and sending the actual log file on the machine? These are stored in %windir%\system32\config.  SignatureTom Porterfield Seriously? Rock and roll! I thought they were buried in some deep crevasse, guarded by a great Sphinx that eats anyone who can't answer his fiendish riddle. Thanks.

Actually, I've run into a problem with this. Grabbing the actual file is out, as it's in use (obviously) by the system. So I genned up a quick temp file, did a copy into it, and emailed that. The emailing worked just fine, but for some reason, the log file is always corrupted. Any clues? Lee Crabtree >> Is there some way to export an event log to a .evt file?
