EventLog Constructor

Initializes a new instance of the EventLog class.

Overload List

Initializes a new instance of the EventLog class. Does not associate the instance with any log.

[Visual Basic] Public Sub New()

[C#] public EventLog();

[C++] public: EventLog();

[JScript] public function EventLog();

Initializes a new instance of the EventLog class. Associates the instance with a log on the local computer.

[Visual Basic] Public Sub New(String)

[C#] public EventLog(string);

[C++] public: EventLog(String*);

[JScript] public function EventLog(String);

Initializes a new instance of the EventLog class. Associates the instance with a log on the specified computer.

[Visual Basic] Public Sub New(String, String)

[C#] public EventLog(string, string);

[C++] public: EventLog(String*, String*);

[JScript] public function EventLog(String, String);

Initializes a new instance of the EventLog class. Associates the instance with a log on the specified computer and creates or assigns the specified source to the EventLog.

[Visual Basic] Public Sub New(String, String, String)

[C#] public EventLog(string, string, string);

[C++] public: EventLog(String*, String*, String*);

[JScript] public function EventLog(String, String, String);

Example

[Visual Basic, C#, C++] The following example writes an entry to an event log, "MyNewLog", on the local computer, using the source "MySource".

[Visual Basic, C#, C++] Note   If "MySource" does not already exist, the WriteEntry method creates it before writing to the event log.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of the EventLog constructor. For other examples that might be available, see the individual overload topics.

    // Write an entry to the log.        
    myLog->WriteEntry(String::Format( S"Writing to event log on {0}", myLog->MachineName ));
