Don't ask people to reply by private email. Most Forum regulars believe solving problems should be a public, transparent process during which a first try at an answer can and should be corrected if someone more knowledgeable notices that it is incomplete or incorrect. Also, they get some of their reward for being respondents from being seen to be competent and knowledgeable by their peers (not to mention the possibility of collecting some of those precious Duke Dollars).
In addition, begging (e.g. "pleaaaaaaaaaaasee") is extremely unbecoming. It's especially annoying when it's coupled with vagueness about the actual problem. Go read the finj - mini-howto. If you have trouble writing the code, come back with specific questions.

I have altered your code. Just a little bit. take a look.
Please do changes accordingly. And better use NetBeans IDE for developing a swing application.

trying to veiw videos from a website that requires me to download firefox and silverlight.My imac osx 10.5.8 will now download firefox. firfx tells me my mac is not compatible with ffox Please help me ? Thank you
There is a version of Firefox 4 available for PPC Macs:
TenFourFox 4.0.1 Firefox 4 For PowerPC Browser Released
Version 4.0.1 of TenFour Fox, FloodGap's port of Firefox 4 for Power PC
Macs that supports both Mac oS X 10.4 and 10.5. has been released.
Mozilla.org dropped support for OS 10.5 after Firefox 3.6 and for Power
PC with the fourth beta of Firefox 4.
TenFourFox uses almost all the same code as Firefox 4 and has nearly all
the same features, including faster JavaScript, WebM video, and HTML 5
and CSS 3 support, as well as new and emerging Web features, but with
the code needed to keep your Power Mac functional and fast. Out of beta
and it's ready for action, versiob 4.0.1 is a performance, security and
stability update incorporating Mozilla's Firefox 4.0.1 plus AltiVec acceler
-ation for WebM and browser graphics, and G5 JavaScript acceleration.
For more information, visit:
http://www.floodgap.com/software/tenfourfox/
Source: from http://www.applelinks.com - posted April 25, 2011)
Now for the intersting bit: TenFourFox, like Firefox, does not support most plug-ins. Unless you are prone to headaches (in which case don't) you can read about that here:
http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported
But there is a workaround!
Open TenFourFox and type in the address bar: about:config (no spaces) and click return. This gives you a warning that it might harm the application. Ignore that and click on 'I'll be careful, I promise' and you get the config file that you can edit - with great care.
Look/search (scroll down) for: tenfourfox.plugins.enabled
Set it to true. (Double click it to toggle it)
Now close TenFourFox, open it again, and Flash will now work, as it now uses the plug-ins that Safari has stored.
With SilverLight, Microsoft attempted to create their own version of what a replacement for Flash could be - but not to universal acclaim. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this new Silverlight stuff, you can download the plug-in from here (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards) if you are using a PPC Mac, but even this will not work with Safari 4. Version 2 only works with Intel Macs and does work with Safari 4/5. The solution is to download and install the latest version of Flip4Mac, which now includes a Silverlight component:
http://dynamic.telestream.net/downloads/download-flip4macwmv.htm
But the latest news is that Microsoft will probably abandon Silverlight in favour of HTML5:

i can't turn off find my ihone, always show "there was a problem when canceling the registration of this iphone with icloud" please help me. i can't restore my iphone before turn off find my iphone
If you are the original owner of the phone and know the Apple ID and password that were used to activate it originally, and if you have an existing backup to restore from, you can force it into recovery mode (which will completely erase it) and restore it as explained here: If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support. When you do you will encounter activation lock, and will have to provide the ID and password used to activate it originally in order to activate it again. If you can't, you won't be able to activate and use it.

cont contact apple server error please help with ipad touch 4. im just fed up with apple please help me because why is it only apple with these kind of problems?
If you mean updae server
Update Server
Try:
- Powering off and then back on your router.
- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- For one user uninstalling/reinstalling iTunes resolved the problem
- Try on another computer/network
- Wait if it is an Apple problem
Otherwise what server are you talking about -
