Examples

The following example handles an EntryWritten event.

#using <System.dll>

using namespace System;
using namespace System::Diagnostics;
using namespace System::Threading;
ref class MySample
{
public:
   static void MyOnEntryWritten( Object^ /*source*/, EntryWrittenEventArgs^ e )
   {
      Console::WriteLine( "Written: {0}", e->Entry->Message );
   }

};

int main()
{
   EventLog^ myNewLog = gcnew EventLog;
   myNewLog->Log = "MyCustomLog";
   myNewLog->EntryWritten += gcnew EntryWrittenEventHandler( MySample::MyOnEntryWritten );
   myNewLog->EnableRaisingEvents = true;
   Console::WriteLine( "Press \'q\' to quit." );
   
   // Wait for the EntryWrittenEvent or a quit command.
   while ( Console::Read() != 'q' )
   {
      
      // Wait.
   }
}

using System;
using System.Diagnostics;
using System.Threading;

class MySample{

    public static void Main(){

        EventLog myNewLog = new EventLog();
        myNewLog.Log = "MyCustomLog";

        myNewLog.EntryWritten += new EntryWrittenEventHandler(MyOnEntryWritten);
        myNewLog.EnableRaisingEvents = true;

        Console.WriteLine("Press \'q\' to quit.");
        // Wait for the EntryWrittenEvent or a quit command.
        while(Console.Read() != 'q'){
            // Wait.
        }
    }

    public static void MyOnEntryWritten(Object source, EntryWrittenEventArgs e){
        Console.WriteLine("Written: " + e.Entry.Message);
    }
}

Option Explicit

Imports System.Diagnostics
Imports System.Threading

Class MySample
    Public Shared Sub Main()
        
        Dim myNewLog As New EventLog()
        myNewLog.Log = "MyCustomLog"
        
        AddHandler myNewLog.EntryWritten, AddressOf MyOnEntryWritten
        myNewLog.EnableRaisingEvents = True
        
        
        Console.WriteLine("Press 'q' to quit.")
        ' Wait for the EntryWrittenEvent or a quit command.
        While Char.ToLower(Convert.ToChar(Console.Read()))<>"q"
            ' Wait.
        End While 
    End Sub
    
    Public Shared Sub MyOnEntryWritten(source As Object, e As EntryWrittenEventArgs)
        Console.WriteLine(("Written: " + e.Entry.Message))
    End Sub
End Class

Remarks

The EnableRaisingEvents property determines whether the EventLog raises events when entries are written to the log. When the property is true, components that receive the EntryWritten event will receive notification any time an entry is written to the log that is specified in the Log property. If EnableRaisingEvents is false, no events are raised.

Note

You can receive event notifications only when entries are written on the local computer. You cannot receive notifications for entries written on remote computers.
