Consider using EventLog Class.

EventLog lets you access or customize Windows event logs, which record information about important software or hardware events. Using EventLog, you can read from existing logs, write entries to logs, create or delete event sources, delete logs, and respond to log entries. You can also create new logs when creating an event source.

I know this question is mighty old, but I spent a good deal of time today building a solution to this so I thought I would share:

        Dim myEventLogEntryCollection As EventLogEntryCollection = New EventLog("Application", System.Environment.MachineName).Entries

        Dim myEventLogEntryArray(myEventLogEntryCollection.Count - 1) As EventLogEntry

        myEventLogEntryCollection.CopyTo(myEventLogEntryArray, 0)

        Dim QueryLog As System.Linq.IQueryable(Of EventLogEntry) = myEventLogEntryArray.AsQueryable

        QueryLog = QueryLog.Where(Function(i As EventLogEntry) i.Source = "MyParticularSourceName")

        For Each Entry As EventLogEntry In QueryLog

            '... your code goes here

        Next

        myEventLogEntryCollection = Nothing
        myEventLogEntryArray = Nothing

Hope it helps others!

You could use additional software called "Log Parser"

Comes with an API you can use, check the help file once installed :)

  • A sample code using log parser would make your answer extremly helpful. Even though I'd rather use internal System.Diagnostics to read the log - Somebody else might find this useful. If you update i will +1 – Piotr Kula Oct 24 '12 at 12:10
