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 Strict
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.
