The data below are limited and simplified but contain information concerning resource, timestamp, state-type, and event_ID. I achieved the desired transformation documented below with loops. My question is, can this be done without loops, in a "vectorised" way? Goal: From this, I want to detect when an error occurs and I want to track it till it ends. It ends when the `State

问题 I want to write these values in the security event log: Console.WriteLine("Level: {0}", eventInstance.LevelDisplayName); Console.WriteLine("Date: {0}", eventInstance.TimeCreated); Console.WriteLine("Forrás: {0}", eventInstance.ProviderName); Console.WriteLine("Event id: {0}", eventInstance.Id); Console.WriteLine("Task: {0}", eventInstance.TaskDisplayName); string sSource; string sLog; string sEvent; sSource = eventInstance.ProviderName; sLog = "Security"; sEvent = eventInstance

问题 I have a function that keeps track of events that happen through out the script. In an effort to use my resources effectively, I decided to compress the data that it generates. However, I keep getting this error: Unknown error type: [2] gzuncompress() [function.gzuncompress]: data error Here's the function: function eventlog($type, $message){ // Types: account,run,queue,system // Set up file name/location $eventfile = '/myprivatedirectory/'.date('Ymd').$type.'.log'; if(file_exists($eventfile)

问题 I want to programmatically create a custom Eventlog view in a C# application. This is how to create a custom Eventlog view with the help of the Eventlog application from Microsoft Windows: I searched the class System.Diagnostics.EventLog for a method that does the same as the button found in the Eventlog Application from Microsoft. Sadly, i couldn't find any functionality that covers my needs. Has anyone ever programmatically created a custom Eventlog view in C# or knows a way that works? 回答1

问题 I am trying to use the ETW functions without success to read the file: C:\Windows\System32\winevt\Logs\Microsoft-Windows-Diagnostics-Performance%4Operational.evtx In order to capture boot time events.

问题 How can i read the windows event log by particular Source, Date time and category?? 回答1: Consider using EventLog Class. EventLog lets you access or customize Windows event logs, which record information about important software or hardware events.

问题 I've gone to some lengths to improve the error handling in my webservice - in particular, showing the StackTrace as in this example: catch (Exception ex) { EventLog log = new EventLog(); log.Source = g_EventSource; StringBuilder msg = new StringBuilder("Exception in UpdateRecord method has been logged:"); msg.Append(Environment.NewLine); msg.Append("passedURL="); msg.Append(passedURL); msg.Append(Environment.NewLine); msg.Append(ex.Message); msg.Append(Environment.NewLine); msg.Append(ex

问题 Has anyone written an event log that uses Isolated Storage in Silverlight 3? Any suggestions on implementing one? Specific questions: Should I keep a stream writer open, or should I open,write, and close for each entry? How should I remove items from the log atomically? 回答1: I heard clog from codeplex is pretty good although it targets wcf, i read on codeproject about about a log4net approach that works for silverlight, although both of these log 2 wcf services, im sure with a bit of tweaking
