Is there a way to execute a function every few secs

Question

I am looking for a function that does something similar to JavaScript's SetInterval() method, basically execute a function every few seconds/millisecs. And keep executing the function until the time interval is cleared. Looks like the roTimeSpan can be used to execute a function after certain time interval but how to make it run continuously until the time interval is cleared?

You can't use roUrlTransfer in the render thread.&nbsp; You will have to use a task that gets run when the timer fires.

In your xml file, define a timer which will repeat every 4 seconds:&lt;Timer&nbsp; &nbsp; id = "SessionRegisterRetryTimer"&nbsp; &nbsp; repeat = "true"&nbsp; &nbsp; duration = "4"/&gt;&nbsp;in your brs file:&nbsp;m.sessionRegisterRetryTimer = m.top.findNode("SessionRegisterRetryTimer")m.sessionRegisterRetryTimer.observeField("fire", "SessionRegisterRetry")&nbsp;where you need to start the timer:&nbsp;m.sessionRegisterRetryTimer.control = "start"&nbsp;then, in the&nbsp;SessionRegisterRetry function, you do what you have to do. In this case it will be called every 4 seconds, after the first call.&nbsp;function SessionRegisterRetry()&nbsp; &nbsp; print "called sSessionRegisterRetry function"end function&nbsp;&nbsp;
