Querying Elements Inside iframe & TabPanel

As it's quite fairly new to me because I've never did Javascript extensively, thus it is difficult for me at first to code it. My recent task required me to extract information from a web page displayed within an iframe, and then create an XML to represent it.

The approach is pretty straightforward after searching the Internet for solutions. All I need is to get the ID of the iframe, and then create an object inside Javascript to point to that iframe using getElementById, and finally invoke the Javascript function of the web page displayed within the iframe.

But then the other task is how to get the list of iframe IDs? There are several iframe elements that will be created dynamically and each of them is going to be an element within an AJAX TabPanel, which in turn will be created dynamically also inside an AJAX TabContainer. If it's just normal HTML element, then it's very straightforward; but with the TabPanel object, I need to find a way to extract only the active viewing tab.

After much searching on the Internet, I found out that it's still possible to extract information from the TabPanel using Javascript. There are predefined functions that can be used directly to refer to each individual or all TabPanel inside the TabContainer. So, without much trouble as well I've finally able to get it done.

Yahoo! Messenger voice call & video call disabled, why?

Was trying to help my colleague to troubleshoot her laptop, where the Yahoo! Messenger voice chat & video chat are disabled even though the setup of the sound & video are all correctly configured.  Yet, it will still throw the error message "Your computer is not connected to the network", which is quite amazingly considered that the wireless network is working plus the Skype is able to make the call. After several finding on the Internet and on some help site, non of the solutions are able to solve the problem.  Then I recalled the other colleague is also using the same laptop and her Yahoo! Messenger is able to use video call & voice call.  I was guessing the whole time of what could be the possible cause that hers is working but not this one.  Then a thought came to my mind, could it be the firewall? The firewall is correctly configured, so what else inside there that is blocking the connection?  The other security software that's installed is the Trend

Sport's Injuries - Treatment for bruises

I have a knock on both my legs last Sunday during a Futsal session. I have a knock on my lower right shin, while sprain my left ankle. It is not a pleasant experience at all to have both legs injured. It is very painful and totally immobilized me. What's important right now is to get it treated. I have tried to elevate both my legs in order to not let the blood concentrated at the injured spot, plus put ice at the injured area. I have even consulted with a doctor regarding the injuries, and am thankful that there's nothing wrong with my right shin. Still, it's not healing that well because the swelling has not resided. Since I'm living alone, it will be hard for it to heal because I need to be mobilize all the time. With the help of the Internet, I'm trying to surf for information that could help to provide first-aid treatment. The following are my finding from the Internet and from family tradition treatment: Elevate the injured leg. Apply ice for about 30

Reserve word in JQuery

I was wondering myself about this the other day when I was trying to resolve an issue where the JQuery AJAX async callback doesn't trigger the session state timeout routine of the .NET properly. I was getting a lot of issues with it particularly because I set a parameter name in the JQuery AJAX call to be "jquery". This actually will cause the JQuery AJAX failed to work. So after I tried to change the parameter to another name, then it works. I was thinking to myself, it could be that the word jquery is a reserved word, so I tried to see if I could find any reference to the reserved keyword in JQuery, but can't find any. So, ought to write it down here to have a reference to remember that I have faced this issue before.
