I'm working on a program to read event log entries from several remote servers...its basically to automate some daily checks we doMy code works but is very slow as the event logs can have up to 60,000 entries in them.I only need to check the logs from the specified date but when i run this it appears to check from the oldest entry to the newest. does anyone know how to reverse the order it looks in? or to save the index it checked from yesterday to a file and only check newer entries next time it's run (obviously i know how to save a number to a file and read it back.. i just mean in terms of the eventlog API stuff!!!)
Dim elevent As New System.Diagnostics.EventLog("Application", currentserver)

View 2 RepliesI am working on creating a web app that will query event logs on internal servers for events using a specific ID. Since most of the servers are running Windows Server 2003, I cannot use the preferred System.Diagnostics.Eventing.Reader method that I was hoping to use.
I've seen the mention of using WMI, but would like to avoid this if possible. I have dabbled with the System.Diagnostics class but cannot seem to get it working when running on a server. It is able, when testing locally, to query my event log, but displays nothing when put on the final server. There is no error that is displayed after the program is ran.
I have a vb.net app that crashes after runnung for 6 hours. There is no error message. Application just stops running. No error noted in log. No flags in event logs. Is there a feature in vb.net that may cause this. Application uses excel 2003

View 3 RepliesI've created an Event Log Source for my application name during the installation process (the end-users are not local admins) and the app writes any error messages to the Application event log.I now want to retrieve the error from the Application log and display them in a grid in my app.
The issue is that it takes more than 30 seconds to retrieve all of the entries,regardless of any filtering I perform in my WMI query. My query is:
"SELECT * FROM Win32_NTLogEvent Where Logfile = 'Application' And Sourcename = 'myApp' And TimeGenerated > '" + DateTime.Now.AddDays(-14).ToString("yyyyMMdd") + "'"
Initially I only filtered on the SourceName but it took 30+ seconds to retrieve about 100 records from 40,000 in the Application log. I added the TimeGenerated filter thinking it would reduce the query time but it was the same.
I tried using the ReturnImmediately enumerationoption property, which does return quickly, but when iterating through the collection it takes over 30 seconds to display the relevant entries.The benchmark I am working against is the speed at which the Windows Event Viewer opens the Application Log and applies a filter on the SourceName. This takes at most 5 seconds to redisplay the filtered list. However, I note that working on Vista, when I open Event Viewer, UAC prompts for admin elevation whereas my code will be reading from the Application log using standard user rights.
I want to search the windows security event log to determine if a certain user has logged in.I am using the system.diagnostic.eventlog class but struggling to display user name/ID information of the logged in account. From looking at the security log I can see that event ID 4624 display logon info. Here is my code so far:
Dim eventLogApp As New System.Diagnostics.EventLog("Security")
Dim eventLogEntry As System.Diagnostics.EventLogEntry
Dim eventCntr As Integer = 1
For Each eventLogEntry In eventLogApp.Entries

Im using VB2008 and im trying to write a little app to basically poll the local event log for an error from an certain application.I consider myself a noob in vb although i have written a few applications.I dont have any code to show you as i have no idea where to start!! So to sum up what i want my app to do is:
1. poll the local event log
2. if it finds an "error" within that hour from this certain app then email me (i have the email code)
I am able to query/read the "Application" event log using System.Management classes in VB.net 2005 (win xp)But I have problem reading the "Message" / "description" of my custom event log.I am getting a System.NullReferenceException{"Object reference not set to an instance of an object."} while reading the "Message" / "Description of the event log while it is reading the others properties.Also when I use System.Diagnostics.EventLog and read all the Events on by one I am able to read the message/description of my custom event log. Why is that the System.Management classes can't read the my custom event log messages while the System.Diagnostics.EventLog classes can read them.The reason I want to use System.Management classes is bcoz I can query my custom event log where as with System.Diagnostics.EventLog classes I have to read the whole event log.
