IDataSource.Delete()

Description:

The Delete method deletes an event (entry) from the event log database.

This method can be called both synchronously and asynchronously.

Syntax:

For synchronous calls:

result = so.IDataSource.Delete(criteria);

For asynchronous calls:

result = so.IDataSource.Delete(criteria, callback);

Arguments:

• criteria:

  This is an object that specifies which event to delete from the log event database. For more information about the object properties and how to define them, see section Criteria for deleting an event.

• callback:

  The callback argument is the name of the method that is executed when an asynchronous Delete call has results or status information to return. You must define this method separately. Follow the instructions in section Defining the callback handler for an asynchronous method to define the callback method.

  This argument is used only with an asynchronous Delete call.

Return value:

If synchronous, the Delete method returns an error code and an error message.

If asynchronous, the method returns an object that contains a transaction ID for the callback instance, an error code, and an error message (see the following table). When the asynchronous call has completed, callback returns an object that contains an error code and an error message (see Table: Callback return value).
