Hello

I am sorry to have to say this but VWG team members are not there to tell you how to code your app. If you need some general programming advice then in my opinion you should post in the public forum.  When you post in the commercial forum, a VWG must answer in the next 24 hour. So when you post non related VWG question, they still have to answer you because of the 24h SLA but I guess their precious time must be used to answer VWG related question first. In my opinion, posts in commercial forum should be related to specific VWG questions.  All other questions must be post in the public forum so anybody can answer you.

Google is also a very good friend when you need some programming advice

Just a thought

Hi Derek,

The general answer to the timer overhead question is that it depends on how many timers you have, how rapidly you need them to fire and how much delay you have while processing the server side request, or polling in your case.

Having a timer that fires every 5 seconds does not add much overhead, but having a timer firing 10 times per second does. So, this is something you will need to experiment with and decide what fits your scenario.

You are correct that there are ways to implement server push technologies, called Comet, but this has not been implemented into Visual WebGui yet, although it is on the plan. You can find one user contributed solution posted on the resources section and you will find a link to that code sample, as well as some general info and other links on the Wiki Comet page.

If your polling for new data takes considerable amount of time, you might also look into implementing something similar to Asynchronous loading of contents ... code sample I posted a while ago on the wiki.

Hope this helps,

Palli
