Request for example Java program
I'm looking for a "Hello world" type example in Java that I can modify and play with. The example code should accept a string argument, display it on a pop-up window. The pop-up window needs to have a button for closing the window. Thanks. —Preceding unsigned comment added by 173.49.11.61 (talk) 00:03, 30 October 2009 (UTC)


 * You want a JFrame example. This is Sun's JFrame tutorial. Once you can make the window open/shut, you want a JLabel tutorial.  The JLabel will be placed inside the JFrame and contain the text.  This is Sun's JLabel tutorial. --  k a i n a w &trade; 02:28, 30 October 2009 (UTC)

Bitdefender uninstalled, but Windows is reporting that its turned off
I've uninstalled Bitdefender, but Windows XP is telling me that its reporting its turned off, even though I've restarted my computer. Do I have to edit some registries or something? The application is gone; I uninstalled it from the Control Panel, so I don't get why Security Center is reporting that it is turned off.--Lucky9109 (talk) 02:07, 30 October 2009 (UTC)


 * This is an off-the-cuff idea only, but how about if you were to install some other (perhaps free) antivirus software, and then take a look at what Security Center states? Maybe the uninstaller doesn't deal with Security Center at all (unsurprising) and maybe Security Center isn't smart enough to distinguish between "off" and "no longer present" (slightly more surprising; I would have thought they would have tested this with all antivirus products that it bothers to recognize).

Someone else's media files on my iTunes: wtf?
Something very strange is occurring on my PC at the moment. I'm staying in a hotel, using a PC that is wireless-enabled, but this particular room is not wi-fi enabled and I'm connected to the net via a cable. I do not have any kind of Bluetooth enabled. I have no idea if any of that's relevant, but I thought I'd mention it just in case. Anyway, on my iTunes there's a whole bunch of media files that don't belong to me, which are certainly not on my hard drive, but which I can watch and listen to through iTunes just fine. On the left hand side of iTunes, under "Shared", it says "[name of person I've never heard of]'s Library". Normally, right-clicking a song title leads me to where the file is saved, but that option is not available to me with these files. A regular search of the hard drive for the song titles brings up nothing. This is freaking me out a little: how on earth can I have access to someone else's media files? And how can I stop someone else having access to mine? --Richardrj talkemail 06:36, 30 October 2009 (UTC)
 * iTunes automatically discovers other iTunes instances on the local network (typically every computer behind the same router) and allows every iTunes to stream (but not download) music from any other instance on the local net. See ITunes. You can disable this sharing via preferences. There also used to be add-ons that would allow you to download the shared files (one of them is myTunes), but I don't know if those still work. By default, nothing is stored on your drive, the music is delivered over the network on demand. --Stephan Schulz (talk) 10:35, 30 October 2009 (UTC)
 * Cool, I never knew any of that stuff. Thanks for the explanation. --Richardrj talkemail 12:35, 30 October 2009 (UTC)

Windows 7 classic start menu
How can I get the windows classic start menu in Windows 7. I hate this new look.


 * There are several third-party apps that will do this. ---—  Gadget850 (Ed)  talk 11:14, 31 October 2009 (UTC)

Beginners programming
I'd like to learn a programming language for my own amusement. Could anybody point me in the direction of a good, free online tutorial & compiler to download, if necessary? The fun to be had is in understanding and applying the logic of a language. I've googled a little, but got lost in the options. I've pretty much no experience. Thanks Stanstaple (talk) 18:35, 30 October 2009 (UTC)


 * Good for you. This is becoming a Computing desk FAQ; it was asked twice on October 27 (search for "language" on this page).  I'll repeat myself that the article Educational programming language may be of interest to you; and I'll go ahead and recommend you learn some variety of BASIC even though SteveBaker hates it.  Comet Tuttle (talk) 20:42, 30 October 2009 (UTC)


 * If you're interested in learning Java (one of the more difficult first languages, but still suitable for dedicated beginners), you'll find a complete tutorial brought to you by Sun. It's very well organized, and outlines exactly what you need to download to get started.--el Aprel (facta-facienda) 20:49, 30 October 2009 (UTC)


 * I'm not a heavy Python (programming language) user, but I think it's a fine first language. Here is a whole page of first-timer tutorials.  The Wikibooks one here looks pretty good.  Please come on back to this desk with the inevitable questions you'll have as you get going.  --Sean 14:05, 31 October 2009 (UTC)


 * Thanks all- Stanstaple (talk) 19:00, 2 November 2009 (UTC)

Stable Motherboard on high temperature
Hello there, Currently I am looking for a motherboard which will be stable on high temperature (36* C or more) and also no freezing or lock up. I have come up with several motherboards in choice.


 * XFX 750i SLI
 * Asus P5 Q P45
 * Asus P5 Q3 P45
 * Gigabyte EP45T UD3R
 * Gigabyte EP43 UD3L

So far I have found the above boards within my budget. Which one I should go for? I am using C2Q 9400 CPU.Thank you--119.30.36.41 (talk) 22:28, 30 October 2009 (UTC)
 * I would recommend a P45 motherboard over a P43. Also it appears you've got some DDR3 and some DDR2 motherboards in there. The DDR3/DDR2 issue was discussed about 2 weeks ago, I suggest you search the archives. Specifically since you apparently live in Bangladesh I would recommend you start comparing 2x2GB DDR2 and DDR3 RAM prices where you live since I'm doubtful anyone here has any idea what the price situation is like there Nil Einne (talk) 08:26, 1 November 2009 (UTC)

IE Tab
Does the IE Tab extension for Firefox render pages using the current version you have installed on your PC, or does it have an internal version of IE which could be different from the version I have installed. I ask because some sites throw errors when viewed with IE Tab, but not with IE natively, and I'm wondering if it has to do with versions of IE. anonymous6494 23:22, 30 October 2009 (UTC)


 * It uses your current version for the rendering. If you have IE Tab installed, go to the Tools menu in Firefox, then select the IE Tab Options item. Note the "External Application" where you can specify which application to use. But the default is Internet Explorer. Also on the IE Tab page on mozdev.org, they list as a requirement that you have "Internet Explorer > 4.0".


 * I don't know why some pages throw errors under IE Tab. Could it have something to do with IE's "compatibility view"? –RHolton ≡ – 13:08, 31 October 2009 (UTC)


 * I have IE 7, so it isn't compatibility view. Thanks! anonymous6494 15:24, 2 November 2009 (UTC)
