EnableRaisingEvents Property

EventLog.EnableRaisingEvents Property

Gets or sets a value indicating whether the EventLog receives EntryWritten event notifications.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public:
property bool EnableRaisingEvents {
	bool get ();
	void set (bool value);
}
/** @property */
public boolean get_EnableRaisingEvents ()

/** @property */
public void set_EnableRaisingEvents (boolean value)

public function get EnableRaisingEvents () : boolean

public function set EnableRaisingEvents (value : boolean)

Not applicable.

Property Value

true if the EventLog receives notification when an entry is written to the log; otherwise, false.

Exception typeCondition

InvalidOperationException

The event log is on a remote computer.

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.

NoteNote:

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

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.
   }
}


import System.*;
import System.Diagnostics.*;
import System.Threading.*;

class MySample
{
    public static void main(String[] args)
    {
        EventLog myNewLog = new EventLog();
        myNewLog.set_Log("MyCustomLog");
        myNewLog.add_EntryWritten(new EntryWrittenEventHandler(
            MyOnEntryWritten));
        myNewLog.set_EnableRaisingEvents(true);
        Console.WriteLine("Press \'q\' to quit.");

        // Wait for the EntryWrittenEvent or a quit command.
        while (Console.Read() != 'q') {
            // Wait.
        } 
    } //main

    private static void MyOnEntryWritten(Object source, EntryWrittenEventArgs e)
    {
        Console.WriteLine("Written: " + e.get_Entry().get_Message());
    } //MyOnEntryWritten
} //MySample
