I'm new, can you help?

i bought a book call "Java in easy steps" and i'm have a real difficulty time trying to compile my first program "Hello world". the book says i can run the comiler by "simply type javac in the command prompt for the java compiler options. when i do that i get this message ' javac' is not reconized as an internal or external command, operable program or batch file. i'm pertty sure i installed java correctly, i dont know what the problem is. anyone have any advice. thanks
oh P.S, i installed Java2 SDK SE 1.4.2_10

Since you are posting to the Java Studio Enteprise forum, I certainly suggest that you try to develop your HelloWorld in our IDE. Believe me, it's much more easy this way :)
Check out the product's website - http://developers.sun.com/prodtech/javatools/jsenterprise/index.html
There are a lot of tutorials (though most of them cover more advanced topics) - http://developers.sun.com/prodtech/javatools/jsenterprise/learning/tutorials/
You may as well want to look at the tutorial for NetBeans 4.1 (it serves as a base for JSE) - http://www.netbeans.org/kb/41/using-netbeans/
However if you decide to stick to the CLI method.. The problem is that you do not have JDK's bin directory in your PATH environment variable. To add it temporarily us the following command: set PATH=<jdk-dir>\bin;%PATH%, where <jdk-dir> is the installation directory if JDK.
If you want to add it permanently, right click on My Computer icon on your desktop, choose Properties -> Advanced -> Environment Variables and modify the Path variable either in the System area or in the user area.

Yesterday, as today's deadline for filing tax returns approached, I was paralyzed by the inability to create new IRS PDF forms and to retrieve archived ones from a year ago. My computer went crazy. 24 hours later, I am still paralyzed. Can you help?

My computer went crazy yesterday on two occasions involving PDF documents. One dealt with attachments to an email from a bona fide corporation. The other dealt with IRS PDF forms & schedules needed for today's submission.
As both dealt with PDF and had nothing else in common, I suspected my PC had a virus. When I asked a local store technician, he agreed. I turned to Norton, which protects my PC from viruses, and after a few hours of really thorough searching, the computer was found to have no viruses.
Before describing what I call "crazy" computer behavior, you need to know that I have long had IE8 as my default browser but a few weeks ago switched to Mozilla Firefox because IE8 had beome incompatible with some websites from which I get information.
When I received the email from AT&T email service and clicked the first of four icons representing attachments, there was figuratively an explosion on my monitor: a series of new tabs, each called New Tab, burst onto the monitor--but no text or picture. The new tabs appeared faster than I coul kill them. I finally decided just to shut down the computer, hoping they would not reappear when I restarted. I was wrong. After 2 repeats, I decided to forget about the attachments and asked the sender to send them to me by regular mail.
That was no solution for my IRS PDFs. I wanted to complete filling in the various forms and schedules that I had begun months ago so that I could mail them today to the IRS (without having to copy them all in ink). When I tried to open the first one, BOOM. The same thing happened: the blizzard of New Tabs atop blank pages; my IRS form or schedule did not show up. Did the same shutdown/restart routine with the same results.
When I looked at the list of current forms that had to be completed, I noticed something very strange: the icons that began the listing of the documents' names were replaced one by one by Mozilla icons. When I moused over them, they said Firefox HTML. Why?
Starting the day today, I had the same experience. What's more, when I started to retrieve 2012 IRS PDFs from a year ago, the same New Tab tabs appeared and had to be killed, and Mozilla icons replaced whatever icon was there before.
Assuming that the problem arose with Adobe Reader's reading of the PDFs, I contacted Adobe but got no helpful phone number because PDFs are a free service and was directed to use this Forum to get help.
What do I have to do to (a) read and use PDFs in the normal way and (b) remove the Mozilla icon from those that have appeared on icon documents. If Mozilla is the source of the problem, shall I go back to IE8? (In my 80s, I want eventually to replace my old computer but for the time being I must continue using it. It will not take an IE9. Anther possible default browser would be Google Chrome, but I have unfavorable impressions of it because of its intrusiveness, loading my PC with stuff I do not need.
Can you help?

The problem is absolutely not Reader. The problem is that FireFox has stepped in front of Reader and handles all the PDF stuff - wrongly in your case. FireFox is DESIGNED to take over PDF files. But it is not capable of doing IRS forms!
To start with go back to IE for these forms. When you save them to disk DO NOT DOUBLE CLICK ON THEM until this is fixed. Just open the in the normal way - start Adobe Reader and use Open from the File menu.

In the previous version, the menu table in table options, there is an option that gives me the option: the Return key moves to next cell. I do not see this option in the new number. can you help me please?

Hi silvano,
If you use a regular pattern when entering values, press enter (return) after entering the last value in a row. That will take you to the first Body Cell of the next row.
Start in Cell B2
1 Tab 2 Tab 3 Enter
4 Tab 5 Tab 6 Enter
7 Tab 8 Tab 9 Enter
Now you are ready to type into B5 .
Another way that some people find easier is to enter one column at a time
Start at B2
1 enter
4 enter
7 enter
etc.
Now start with C2.
Use whatever suits your work flow.
Regards,
Ian.

I am a former user of Adobe Photoshop CS3 as a very beginner. I wish to know if Creative Cloud will do everything that Photoshop CS3 did for me. I am very confused with all these new products. Can you help me?

Please can you help....
I ordered an iPhone 5s in early September from the orange shop in Chamonix Mont-Blanc France.
I needed a new phone as i dropped my iPhone and broke it so it thought i would upgrade.
I was asked in the shop if I wanted a black or white one, I asked for a Black one, as all my iPhones have all been Black as I DON'T LIKE White ones. (sorry)
I was told my phone would arrive in a week so I waited with broken phone for new one. The following week I was told it would be the following week, the following week i was told the same but the assistant in the shop told me they would ring me when it arrived. Three days later i recieved a text from the shop to say the phone would be in tomorrow, when I went in they said it had not arrived and they would call me when it was in the shop.
They called me on Thursday the 17th of October to say the phone was in the shop.
I arrived at the shop at 6:00pm after my work, the shop closes at 7:00pm. I recieved the phone, signed for it and extra unwanted insurance with I was told I could only canceled in a month. I was then told they didn't have any sim cards in the shop, i said no problem the Phone i assume will need charging so i will take it home and charge it and return for the sim tomorrow.
So the Phone remained boxed.
When I returned home and opened the box I realised it was a white one, I replaced the lid put it back in the bag, and returned it to the shop first thing Friday 18th October, to point out the error, only to be told "to bad" ?? I was told I could have changed it the night before but not this morning? They said I had ordered a Black one but as I had signed for a White one nothing can be done. I was angry and left the shop. I returned later the same day with a French friend to try and resolve this problem, as I wasn't sure if something was being lost in translation. I didn't think I was being unreasonable, it is a very expensive piece of equipment and this wasn't what i wanted. They told my friend that the phone was not available in Black, that was the 5, and that the 5s was only available in silver and gold, and that mine was a silver one.
I then thought it was my mistake as it was a new phone. She put a sim in the phone put it in the box and I left for a business meeting only to arrive and see a Black iPhone 5s sitting on the table??
So I then returned back to the shop with the Black one and mine still all boxed and untouched to prove they had blatantly lied to me an hour ago, only to be told that there was nothing they were prepared to do.
Is this fair practice ? I am at a loss with this and am looking for help ?

A minor point, but it may avoid a little confusion if, instead of saying "black" in reference to the iPhone 5s, say "space gray":
"iPhone 5s — Available in silver, gold, and space gray" (Source)

Can you help I was having problems with my iPod so I restored it but I accidentally set it up as a new iPod is there any way to restore it from an old backup when I right click iPod in iTunes there isn't one anyway to recover one or find it on computer

Hi can you help I was having problems with my iPod so I restored it but I
accidentally set it up as a new iPod is there any way to restore it from an old
backup when I right click iPod in iTunes there isn't one anyway to recover one
or find it on computer

The following says how to restore from backup.
iOS: How to back up
If you go to iTunes>Preferences>Devices you can see if you have an iTunes backup. You need one dated before or the exact time you started the restore.

I have looked at the "More" part but again radio is not an option.
Can you help?

Just wait a bit. Turn it off, then back on.
I don't know why, but after the update it doesn't show up right away.
When it finally does, you will find a red icon on the bottom of the screen, on the left side.

I have Adobe 5.0, original disk, 6.0 upgrade, original disk, and Adobe CS2. I'd like to install in my new computer with Win.8.1. Can you help?

Forget about all the versions you already have (5.0 through to CS2). They will no longer work and the serial numbers are redundant.
Download the non-activation version of CS2 form the link provided by kglad and use the new non-activation serial number provided at that link. Your existing serial number(s) will no longer work.
Note: there is no guarantee that CS2 will run well on Win 8.1. Try it and see.

Hello pryan1012,
What this message means is that you have more music in your itunes library than there is free space in your ipod.
I had this same issue at one time. This is what helped me put my music on the ipod. I used manually manage.
Learn how to sync muisc here.
Hope this helps.

Did you use TimeMachine to restore your files?
Did you install the app or restore?
Makes a lot of difference to specify just how you swapped out and what you did.
Are you running Mountain Lion or older?
And you realize this is not forum of notebook users...

The new version of iTunes doesn't recognize my iPod shuffles where the old version did. Can you help?

I downloaded the new version of iTunes today-it doesn't recognize my shuffles-the older version did. Can you help?

Ok people after messing up three days with my jailbroken ipod touch cauze my itunes didn't recognize it i figured out that the problem is first windows recognized it as a imaging device o as a camera, i found in the device manager was listed mi apple ipod under portable devices and there was the problem it has to be listed under universal serial bus controllers named as a apple ipod so this is what i did but first make sure u have correctly installed itunes and the apple mobile device support:
1 open the device manager or windows button + r is run and then type devmgmt.msc
2 look for the portable devices and find the apple ipod or wherever that is listed on your pc.
3 once u find the apple ipod do a right click on it and click on uptade driver software
4 take the manualy opcion or browse on my computer and then look for this folder on your computer C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers
there should be the driver that itunes recognize and your windows wont recognize your ipod as a camera again but i repeat u have to make sure u have installed the apple mobile device support u can get it by extracting the itunes+quicktime package using winrar. so click on update or next what ever on the update process and next time itunes will open your ipod for sincying thanks to forums ilounge.com
