It also contains the code executed when events are raised. The code specifies the initial and terminal states of the form.

When the full time (9.84 seconds) has elapsed, the first text box displays "Until Now" and the second displays "9.84". When you click the button, the first text box displays "From Now" and the second starts to count seconds. The example also uses a form ( Form1) with a button ( Command1), a label ( Label1), and two text boxes ( Text1 and Text2). When the class raises the event, that event is fired on every class that has elected to sink events for that instance of the object. An event source can have multiple sinks for the events it generates. The class that raises an event is the event source, and the classes that implement the event are the sinks. The code illustrates all of the event-related methods, properties, and statements, including the Event statement. The following example uses events to count off seconds during a demonstration of the fastest 100-meter race. You can declare event arguments just as you do arguments of procedures, with the following exceptions: events cannot have named arguments, Optional arguments, or ParamArray arguments. ' Declare an event at module level of a class moduleĮvent LogonCompleted (UserName as String) A typical event might be declared and raised as shown in the following fragments. An event can't be declared to return a value. A syntax error occurs if an Event declaration appears in a standard module.
Data type of the argument passed to the procedure may be Byte, Boolean, Integer, Long, Currency, Single, Double, Decimal (not currently supported), Date, String (variable length only), Object, Variant, a user-defined type, or an object type.Īfter the event has been declared, use the RaiseEvent statement to fire the event. Name of the variable representing the argument being passed to the procedure follows standard variable naming conventions. Indicates that the argument is passed by reference. Indicates that the argument is passed by value. The arglist argument has the following syntax and parts: Name of the event follows standard variable naming conventions. Note that events can only be raised in the module in which they are declared. Specifies that the Event is visible throughout the project. The Event statement has these parts: Part
