Answer 1

Create a Timer in Sysyem.Timers Namespace.

http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx

//Create a timer with a five second interval.

aTimer = New System.Timers.Timer(5000)

Answer 2

To create the actual timer,  the previous example is perfect.  ( the 5000 represents the interval in milliseconds )

But, to make it actually do something every 5000 milliseconds (5 seconds), you have to add the following :

aTimer.Tick += new System.EventHandler(TimerTick);

public void TimerTick(object sender, EventArgs e)

{

//Put the code to be executed here

}

Answer 3

Note that the System.Timers Timer raises the Elapsed event on a ThreadPool thread and if you want to manipulate GUI controls and component you should use the Timer's SynchronizingObject to synchronize the event with the GUI thread. Another option in this case is to use a Windows.Forms timer.

Hi

I have a WPF app with a single thread, it has a timer and some controls to paint the screen. 

the timer's callback function does not allow running any function of the main thread.

the Windows.Form.Timer does not exist.

how do I synchronize the timed out event with the main thread functions?

thank you

 

Answer 5

For anyone who has the problem with STA running in another thread when using the "System.Timers.Timer ",

you should use this  "System.Windows.Threading.DispatcherTimer" instead.
