there is no "best", at most there might conceivably be a "best" for a specific purpose under specific conditions.

I guess they're all USB devices? If so (and especially if they're connected through a USB hub) you may have power problems. If you can't get enough electrical power to the devices (many unpowered USB hubs have that problem when they're full) some or all may fail.

The problem with offering many different versions is that it's extremely expensive to create. If they create many different interfaces to the same product and sell it as one with many options it gets even more complicated and bloated. Modular programs are nice, the user can basically choose the parts …

And remember: other countries have similar programs.

And do your own homework. Why should we do your work for you if you're too lazy to do it yourself?

hmm, I think he wants far more. He seems to want to get a complete directory structure of someone's harddisk (with all files involved) from a remote location. That is (happily) impossible. What is possible is asking a program on the other computer (in a P2P environment you'd have programs …

post in the correct forum and you may get help.

At least not current production versions. It's sometimes possible to find heavily discounted old software in bargain bins of course.

if something goes wrong you're likely to loose the hardware so having multiple partitions will do you no good :) I agree it's more prudent to have several smaller disks, but 100GB or so isn't excessive for today's overly large applications (which seem to have often been designed to use …

RFID can indeed be abused by oppressive governments (which at last count meant all governments) and corporate entities. But the myth that RFID tags "call home" to tell the government where you are regularly is just that, a myth. RFID tags of the kinds which could be used for implantation …

tools.jar doesn't need to be (in fact shouldn't be) on the classpath. What is missing from the classpath is the current directory ('.'). On older machines running Windows 9x that's no problem, on NT based and Unix based operating systems it's required.

I've seen that sometimes, usually booting the machine gets rid of the gremlins. If it doesn't (in this machine it may have been a flaky connection building up static charge) you should just replace the drive, CD drives cost next to nothing.

[QUOTE=marvis4life]FireNet, i've got it. but have not known how to use it. it's always giving the message: Failed to locate protected mode loader (DPMILOAD.EXE). can u put me thru. in using it? thanks.[/QUOTE] That sounds like a DOS compiler wanting to switch to DOS protected mode. What are you using? …

correct, a lack of power will lead to hardware sometimes not working. For example when I first installed a DVD writer one of my harddrives would no longer work, but only AFTER I'd used the DVD drive. After rebooting the drive would work again. When I disconnected the DVD drive …

Sorry, not going to hand over my email address to a company I've never even heard of. Enough harvesting for spam purposes going on as it is. Religion is a means of explaining away things you don't understand in terms you do understand. Once it gets organised it degenerates (or …

Get yourself to a decent bookstore and get some good books on HTML and Java[b]SCRIPT[/b]. That (and experimenting) is the best way to learn.

plz c ????? Please translate that into proper English so people who are not well versed in gobbledegook can understand you. Same with parts of the rest of your post...

what are you trying to achieve? Is the password entered by the users and the program checks it (with the users getting a new password mailed every week)? If so the solution is simple: save the password in the form of an MD5 hash and compare the MD5 hash of …

I've a similar experience with a 4000 series Satellite. After about a year the motherboard died (which was replaced under warranty), a year later the battery started to go (I ditched it eventually as I rarely used the machine on battery anyway). The latch for the lock broke off at …

change this [code]private float d = 2.0f, sum = 1.0f, term = 0.0f;[/code] It's very bad practice to declare multiple variables on a single line, never do it!

Many C answers are relevant to C++ as well to some degree even if the reverse isn't always the case. Therefore a true separation may not be appropriate on purely language boundaries. Separation on functional boundaries might be more appropriate (general language issues, GUI programming, etc.).

Seems to me you don't understand much about socket communications. Programs don't create ports, they open sockets on ports. That's easy enough to do in Java, any book on network programming in Java will tell you how (and you'd better study such books as otherwise you're in for a load …

remember the practice is illegal in many countries, and illegal for minors (which appear to be a large proportion of the visitors here) in many more.

that depends on your operating system. At the least you must restart your terminal windows and Java based applications for them to see the change.

The passport would contain the biometrics data on a chipcard or something similar. We've here already a stiff plastic card embedded in the passport which contains a digitised photograph and signature, adding a chip to that would be easy. To verify identity (if in doubt from the photograph and other …

The majority of virusses spread via pirated software and other crap people download over P2P networks. Email virusses used to be big but have been on the decline for a year or more. Direct infection through websites is low and generally not viral in nature but limited to installation of …

(s)he's need an exam in advanced gobbledegook to understand your post. Not that I understood much of it, except the words "exam", "course", and "studying"...

you mean those freaking homework questions that require only a little freaking bit of effort to get a freaking simple solution for? ;)

A public class needs to have the same name as the java file it's contained in. A class must also be public in order to be able to run as a program AND have a main method with the correct signature.

No, that won't stop the thread. It will remove the reference to the thread but won't stop the process. What you do is set a flag in the Runnable from outside the process and check for that. If the flag is set, terminate the run method.

Classes can extend only 1 other class (as well as implementing any number of interfaces). Interfaces can extend any number of other interfaces (but can't implement anything obviously). So you can have something like [code] public interface MyInterface extends List, Serializable, Comparable { //... method declarations } [/code]

The book by Sierra and Bates is excellent. After an official Sun training course (which you might think overly expensive at this point :) ) I used it exclusively (besides tons of realworld experience). It's the book most used, many people that fail the exam admit to using something else …

Check if you have a rule in operation somewhere.

HF Java is an excellent book but doesn't prepare you for the exam. The certification study guide will prepare you very well indeed if you have a decent knowledge of the core language which Hf Java will provide. Oh, you got the names almost right except it's Kathy (with a …

more likely it was slashdotted :)

Blind people have been able to use text based applications for decades using specialised Braille reading hardware which turns lines of text into Braille code. They can be taught to type blind (as can sighted people). Operating Lynx you activate URLs and formfields purely using keyboard commands, so no mouse …

Jive is nice (I may be biassed, I wrote part of it ;) ). It's not free anymore though (but I do have the last free version somewhere).

You need to specify the width of the table to accomplish that. I don't use Struts so I can't tell you how to determine the width of the panel at runtime to feed it to the table declaration.

And visit [url]http://www.javaranch.com[/url] You might also consider Sun training course SL275 which covers most of the stuff on the exam (and you end up with some very nice books).

The software I would choose is Jive. Works very well and is fast and secure (Sun uses it for their forums, as does Novel and several others). No longer free, but while it was I helped in development so I may be biassed ;)

no, there's nobody there. All equipment that has an electrical current flowing through it will transmit radio frequency emissions. Apparently your crappy cheap digicrap and/or your cable are extremely poorly shielded and happen to transmit at the exact frequency at which your crappy cheap radio receives. Freak coincidence. And yes, …

Sorry, for professional assistance you'll need to pay a consultant. We're only doing this as a hobby (at least while contributing to this site).

There's a lot of information on JavaWebstart, read it. And if you'd read other replies you'd know by now that you do NOT make exes out of Java classfiles. There are some expensive tools out there that can do it, which a search engine should turn up, but that completely …

And don't become impatient when you don't get an answer in 5 minutes.

They actually signed a contract to start building such things and cooperate about a year ago :) Excellent development, bringing 2 good companies that both are entering rough waters together in a joint effort.

remember that JFrame is derived from Frame which derives from Component (or something like that), many core methods are inherited from a parent class.

1) anything from a large room with dozens of desks to a decent sized office of your own. 2) at the moment about €35000 a year, plus pension and health insurance plus profit share (about €2500 a year). At the peak of the .com boom about the same plus company …

Dell and Compaq (especially Compaq) are the market leaders. I'd not buy anything off eBay, the risk is just too high. Not only a lot of scammers and bait&switch operations, but what if you need service? Will that reseller be around to take in your warranty repair and handle it? …

It's a double edged sword. If you do it often you use a little time frequently which may in the end cost more time than doing it infrequently. But when you do it infrequently each time will take a long time indeed (and may in fact need several runs to …
