Embedding QuickTime 3D tour[edit]

Hi, I have one of those QuickTime 3D tour video, where the user can look at a place in virtual 3D by moving their mouse around and clicking. How do I embed it into a (x)HTML file? Thanks. Jamesino 01:04, 22 March 2007 (UTC)

If you mean QuickTime VR, then has instructions on Including QuickTime In A Web Page and Embedding a QTVR Movie in a Web Page. --Canley 07:38, 22 March 2007 (UTC)

3 monitors on Radeon 9250's[edit]

I currently have a PCI Radeon 9250 (128mb)running a 17" Relysis TE770 on my VGA output, a 17" iiyama LS704U on the DVA output (through a VGA converter - which gives an awful picture!) and a TV on the S-Video cable. What I want to do is run both the monitors as an extended desktop, but also the TV as a mirror or a further extended desktop. However, my ATI software only allows me to activate one of these secondary monitors in the "Displays" tab. To overcome this my girlfriend has invested in a Radeon AGP Radeon 9250 (128mb) (for my birthday so I can't actuall tinker about until 29th) because I read that I could enable further monitors through a second graphics card. Is this correct or will I encounter problems. CrazyFoolMrT 01:10, 22 March 2007 (UTC)

Your PCI card, and your AGP card are both DUAL HEAD video cards, this means they can only spit two outputs out at any one time, even if they have 3 sockets. Unfortunately, AGP and PCI cards don't like to work together as they use the same harware interrupt or something like that. This was asked recently here and that's the most we could come up with.. If you want to run more then 2 displays, you can get a second PCI card, or a quad head (or more) video card. Vespine 03:05, 22 March 2007 (UTC)
Thanks Vespine, but this page suggests you need an AGP and a PCI? I am confused? CrazyFoolMrT 01:11, 23 March 2007 (UTC)
You can have extended desktop on 2 monitors plus a clone of either one on a TV, but otherwise you can't do it easily. --antilivedT | C | G 04:39, 22 March 2007 (UTC)
I don't mind not being able to do it easily.... Whats the hard way? CrazyFoolMrT 01:08, 23 March 2007 (UTC)
I believe the hard way is the same as my solutions above and involve buying new hardware. Nothing you can do will make your card spit out three images if it only has two pieces of hardware that can output video. And I believe it is not possible to run a PCI card and a AGP card at the same time, that was my answer last time and no one refuted me so I still believe that. Vespine 05:51, 23 March 2007 (UTC)

Google Cache browser[edit]

Is there a site I can go to so that I can navigate through the internet using Google's cache instead of normal browsing? I would like that a lot for some specific applications. Thanks! [Mαc Δαvιs] (How's my driving?) ❖ 06:10, 22 March 2007 (UTC)

Sure thing Mac: Do a Google search for a topic or website, and just after the URL (probably green text), on the bottom line of each hit, you will see a link to "Cached" (probably pale grey-blue text). − Twas Now ( talkcontribse-mail ) 08:41, 22 March 2007 (UTC)
You can track - which is the Wayback Machine, which has old caches of webpages for the past several years - although it isn't always easy to navigate quickly. Rfwoolf 14:06, 22 March 2007 (UTC)

I mean that I want to be able to click on the "Cached" and be able to click in that cached page on links, that lead to other pages in the Google cache. [Mαc Δαvιs] (How's my driving?) ❖ 19:02, 22 March 2007 (UTC)

Offhand, I don't know of an easy way to do this. One approach would be copy the URL of the link into a Google search, then click the "Cached" version of that URL. This would require quite a bit of bouncing around, though (browser bouncing?). − Twas Now ( talkcontribse-mail ) 21:26, 22 March 2007 (UTC)
It's not perfect, but if you use Firefox then this extension will add a Google cache: shortcut (amongst others) to the right-click menu on links. There are others with similar functionality if you search the Firefox addons site for Google cache. — Matt Eason (Talk &#149; Contribs) 22:04, 22 March 2007 (UTC)

how does midi to wave converter works?[edit]

how does midi to wave converter works using with the help of pulse code modulation technique? —The preceding unsigned comment was added by Ket 31 (talkcontribs) 07:43, 22 March 2007 (UTC).

It works pretty darn well!  :-) Read about it at Synthesizer, General MIDI, and MIDI. —EncMstr 07:52, 22 March 2007 (UTC)

UNICODE website[edit]

Can any one Please Help me to Build an UNICODE website ? IF Possible please send me a piece of code.Also, instruct me for the intial setup. Its Urgent Can any one help out . —The preceding unsigned comment was added by Krishna.logic (talkcontribs) 10:56, 22 March 2007 (UTC).

Unicode is just a character encoding standard, like ASCII. Most modern web development tools support it, like Notepad, Dreamweaver and Visual Studio. — Matt Eason (Talk &#149; Contribs) 12:58, 22 March 2007 (UTC)
Hi ,
Thank's for the Reply.But i do webdesig, I am not aware of how to start building a Unicode website.So, i need to know whether to make the Unicode usage entry at the start as
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
of my building the page and just go on with the HexCode by, that will do.
Or is there anything else needed before i use the HEX Code.
Kindly guide me in this regards,
No, just set your Content-Type charset to UTF-8 and make sure you actually save the file as UTF-8 (it's in the 'Encoding' dropdown when you save a file in Notepad). You can set Dreamweaver to use UTF-8 using these instructions. — Matt Eason (Talk &#149; Contribs) 00:37, 26 March 2007 (UTC)


Is it possible to get an alert whenever a web page changes? I'd like to get alerted whenever my "my watchlist" page gets a new entry. Zain Ebrahim 12:50, 22 March 2007 (UTC)

I don't know if it can be done directly, but per-article check out WP:RSS. I think user:kylu has an RSS from her watchlist. Unfortunately, she's on wikibreak, so you might have to look at old versions of her user page to see. —EncMstr 15:40, 22 March 2007 (UTC)

Lazy Man's P2P[edit]

Is there a P2P out there, where instead of having to search for things one by one, I can just feed it a list of things I want downloaded, and it will download the closest matches? For this particular project, it would save me perhaps hours of time. 14:00, 22 March 2007 (UTC)

I guess you could use a BitTorrent search engine like isoHunt? Probably not exactly what you specified but meh. Splintercellguy 15:00, 22 March 2007 (UTC)
If you are somewhat computer savvy and are using mldonkey you can try this -- Diletante 16:00, 22 March 2007 (UTC)
Thanks. I am quite computer savvy, but I couldn't communicate with the console (running Windows XP), and the addon you gave me (MLautosearch) has a type of virus - according to my Norton Antivirus - but I think it's just overreacting over the one file that somehow communicates with the network. 19:38, 23 March 2007 (UTC)

Executing An .exe file[edit]

I downloaded the game fifa street for pc which is a single exe file but when i click on it a command prompt window pops up and stays for 2 seconds and then closes itself. I tried doing this a lot of times but the same thing repeats. Is there anything i can do and what is going on i mean what happens to it? —The preceding unsigned comment was added by (talk) 15:53, 22 March 2007 (UTC).

Here's how:
  1. Explicitly open a command window.
  2. Drag-n-drop the .exe file into that window; it's full path will appear in the command window as if you'd typed it in.
  3. Press {Return}; the program will execute.
Any messages it displayed should remain in the command window for your inspection.

You might want to read Trojan horse (computing). -- Diletante 16:06, 22 March 2007 (UTC)
Our questioner has already run it :-(, 'might as well see what it's saying, even if it's just "pwned!". Well, unless you think the trojan is set to go off only on the, say, tenth run ;-).
Atlant 12:16, 23 March 2007 (UTC)
You open a command window, by the way, by going to Start -> Run and then typing in "cmd". Also it sounds pretty dubious to me, potentially a virus. -- 20:16, 22 March 2007 (UTC)
If it isn't something sinister, it might need a .dll or .ini file or something. Anchoress
How big is the exe? It could be that you've downloaded a cracked executable or a patch for the game instead of the whole thing. If it's anything under 50mb, then it's not the full game at all, and it's no use to you. Johnnykimble 09:23, 23 March 2007 (UTC)

Linux on a CD drive -less Tablet PC[edit]


I have a Thinkpad X41 tablet PC, and am looking to start using linux, on a part time basis. I am currently using Windows Xp. However, the laptop that I am presently using does not have a CD or floppy drive. It does have USB.

I was wondering if there is anyway that I can run a strand of linux (ubuntu, or anything similar). It does not have to be a fully immersive experience, a simple mounted cd emulated version would work. I seek no special tablet functions, only the ability to experience linux.


Jon —The preceding unsigned comment was added by (talk) 17:04, 22 March 2007 (UTC).

This may be an obvious suggestion, but why not use an external USB hard drive? The only trick would be installing the appropriate boot loader on the drive to let you boot from it, but a Live USB installation could probably manage it. Less flexible but more ready-made would be to use a USB CD drive (although you might be hard-pressed to find one not made expensive by supporting more advanced things like DVD burning), with which you could use a LiveCD and even install a distribution (which might require repartitioning to preserve Windows) if you liked it. Alternatively, if you want just a bit of Linux-ish flavor, you could try out Cygwin, which creates a Unix-like environment within Windows. For further information and personal assistance you can likely contact your local LUG. --Tardis 20:28, 22 March 2007 (UTC)


You could also try Damn Small Linux - it can boot from normal USB sticks. Aetherfukz 14:47, 28 March 2007 (UTC)

IT-enabled Investments[edit]

what is the exact meaning of IT-enabled investments. i m askig this question with reference to COBIT. an answer with a precise real-life example is what required. thanx in advance —The preceding unsigned comment was added by (talk) 17:31, 22 March 2007 (UTC).

Windows Registry[edit]

Where, if anywhere, and how, is the Windows Registry stored on a computer? (I understand what the registry is and what it does). --JoeTalk!Work 19:24, 22 March 2007 (UTC)

See Windows registry#Registry_locations. —EncMstr 19:42, 22 March 2007 (UTC)

U may be right but i really need an answer —The preceding unsigned comment was added by (talkcontribs) 2007-03-23T16:30:40 (UTC)

What kind of answer do you need? —EncMstr 17:21, 23 March 2007 (UTC)
if you are having a problem with something like *.vxd , then type "system.ini" in the run command. Be careful what you change there, it is one of the keystones of an operating system....J.delanoy 16:08, 27 March 2007 (UTC)

Remote Assistance[edit]

Im looking for a free alternative to Windows Remote Assistance. One that is much more reliable. I used to be able to get into peoples computers no problem with RA but i havent been able to connect to someones computer for so long.

thank you Omnipotence407 19:40, 22 March 2007 (UTC)

RealVNC may do the job, though it does not have features for restricting control for the remote user. On another note, did the person check his firewall/router? Splintercellguy 00:02, 23 March 2007 (UTC)
Sorry i wasnt more clear. my "someones" was supposed to be "anyones." Ive had them turn off whatever firewall they have, and i even shut down mine. RealVNC seems pretty complicated. If it can be easily explained to me, that would be great. I know how to use computers pretty well, but the website isnt very clear Omnipotence407 18:07, 24 March 2007 (UTC)
Maybe this can help you: Tech support with UltraVNC SingleClick, its among the easiest programs to setup for the support user. Aetherfukz 14:50, 28 March 2007 (UTC)

Saving Streaming Video[edit]

Hi, I saw a funny video on youtube and I was wondering if there was a way to save it to my computer and possibly on a usb drive before it gets pulled? Is there any way to save streaming video?

default programs for Windows Vista[edit]

I just installed Vista a few days ago, and most things are working correctly, though I am having trouble with the default programs. I have Vista business, and when I go to "Default Programs", I click on "Set program access and computer defaults", and then I change my browser to Firefox and my media player to iTunes, and then I save settings. However, next time I open Firefox, it says it is not the default browser, and when I look at the default programs again they are back as before. No matter how many times I do it, my settings are not saved. What can I do about this? —Akrabbimtalk 20:32, 22 March 2007 (UTC)

You may have to go into each of the relevant programs and tell them to not check if they are the default program for that service, and disable any settings that say "Make [this program] the default program for [whatever]". Then, specifically go to the programs you WANT to be the default, and see if they have a setting that says "Check if [X] is the default program for [Y]" and "Make [X] the default program for [Y]". However, if none of the relevant programs are running, and you go in to Default Programs settings in Vista, and you make your changes and 'Apply' and close, and you still don't run those programs, then, if you go right back into Default Programs, all your settings should still be there. As a last resort, try rebooting your computer AND/OR pressing Ctrl + Shift + Escape and shutting down all unnecessary services including Internet Explorer, Firefox, iTunes, etc. Rfwoolf 08:34, 23 March 2007 (UTC)
