The service that compiles the instructions for shipping operates on a batch of orders rather than processing each order individually. You could use a Timer to start the batch processing every 30 minutes. Timer class has the same resolution as the system clock. This means that the Elapsed event will fire at an interval defined by the resolution of the system clock if the Interval property is less than the resolution of the system clock.
For more information, see the Interval property. When AutoReset is set to false , a System. Timer object raises the Elapsed event only once, after the first Interval has elapsed. To keep raising the Elapsed event regularly at the interval defined by the Interval , set AutoReset to true , which is the default value.
The Timer component catches and suppresses all exceptions thrown by event handlers for the Elapsed event. This behavior is subject to change in future releases of the. NET Framework.

Note, however, that this is not true of event handlers that execute asynchronously and include the await operator in C or the Await operator in Visual Basic. Exceptions thrown in these event handlers are propagated back to the calling thread, as the following example illustrates. For more information on exceptions thrown in asynchronous methods, see Exception Handling. If processing of the Elapsed event lasts longer than Interval , the event might be raised again on another ThreadPool thread. In this situation, the event handler should be reentrant.
The event-handling method might run on one thread at the same time that another thread calls the Stop method or sets the Enabled property to false. This might result in the Elapsed event being raised after the timer is stopped. The example code for the Stop method shows one way to avoid this race condition. Even if SynchronizingObject is not null , Elapsed events can occur after the Dispose or Stop method has been called or after the Enabled property has been set to false , because the signal to raise the Elapsed event is always queued for execution on a thread pool thread.
One way to resolve this race condition is to set a flag that tells the event handler for the Elapsed event to ignore subsequent events. If you use the System. Timer class with a user interface element, such as a form or control, without placing the timer on that user interface element, assign the form or control that contains the Timer to the SynchronizingObject property, so that the event is marshaled to the user interface thread.
For a list of default property values for an instance of Timer , see the Timer constructor. Be aware that. NET includes four classes named Timer , each of which offers different functionality:.
Initializes a new instance of the Timer class, and sets all the properties to their initial values. Initializes a new instance of the Timer class, and sets the Interval property to the specified number of milliseconds. Gets or sets a Boolean indicating whether the Timer should raise the Elapsed event only once false or repeatedly true.
Gets the IContainer that contains the Component. Gets a value that indicates whether the Component is currently in design mode. Gets or sets a value indicating whether the Timer should raise the Elapsed event. Gets the list of event handlers that are attached to this Component. Gets or sets the interval, expressed in milliseconds, at which to raise the Elapsed event. Gets or sets the site that binds the Timer to its container in design mode. Gets or sets the object used to marshal event-handler calls that are issued when an interval has elapsed.
Begins the run-time initialization of a Timer that is used on a form or by another component.
Releases the resources used by the Timer. Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. Releases all resources used by the Component. Releases all resources used by the current Timer. Ends the run-time initialization of a Timer that is used on a form or by another component. Retrieves the current lifetime service object that controls the lifetime policy for this instance.

Returns an object that represents a service provided by the Component or by its Container. Gets the Type of the current instance. Creates a shallow copy of the current Object. Creates a shallow copy of the current MarshalByRefObject object. Starts raising the Elapsed event by setting Enabled to true. Stops raising the Elapsed event by setting Enabled to false. Returns a String containing the name of the Component , if any. This method should not be overridden. Occurs when the component is disposed by a call to the Dispose method.

KB Diamond Member Jan 9, Nov 8, 4, 4 I haven't done the compact framework, but System. Timer exists in the Compact framework and should work if it is in there. Also you can try this one: Jul 23, 0 0. Use this when you need to perform periodic background tasks on another thread. This actually dispatches a request for callback in the originating thread's message queue. Meaning the thread that sets the timer is guaranteed to be the thread that executes the callback! This also means that only one thread is doing all the work.
This is a wrapper around System. If your understanding of threads is competent, I would suggest not using a timer for a server application. I have always experienced timers not "going-off" when the server is quite busy. I usually end up using an endless loop on a background thread, do all my work, and then call Thread. Sleep , thus allowing other threads to do their work. Hope this helps. I didn't notice before that you were using the compact framework.
