CS3 - Classroom in a Book - Help for real beginner please!

I'm literally only on lesson 4 of this course so please forgive my ignorance! Using the Quick Selection Tool the course tells me to " Choose Edit > Copy and Edit > Paste to paste the selection on a new layer." I get a message which says "could not complete the Copy command because the selected area is empty".
I'm sure there is a simple explanation but I just can't find it - please can anyone help this pure beginner from going entirely mad?
Judy

Is the layer that you want to copy from the active layer? In the example below I used the quick selection tool to select some of the image (you can see the "marching ants" in the lower right corner), but since a new empty layer is active and not the layer I want to copy from, the error message you describe is displayed.

Helping an absolute beginner

When I got my very first Mac, a Mac SE/30, I seem to remember there being a tour you could take to learn what the hard drive icon is for, what the desktop and windows are, how you move and resize windows, what double-clicking is, and so on: the absolute basics. Do current macs come with something like it? My father just got a MacBook Pro, but it's hard for me to help him get online, for example, when he has no idea what the desktop is. (I don't live in the same city, so all my help is by phone.) I have a by now fairly old Macbook Pro, but I really don't remember what it came with.

New Macs come with a user guide that provides some basic introductions to using the computer and software, but there's no online tour such as was available with old Macs. If you do some searching you may find some third-party tutorials. You will find numerous online tutorials provided by Apple: Apple - Support - Mac 101. Some elements are video. This site lists 195 free video tutorials for Mac users.

Help for a Beginner's Program

Hello, I'm fairly new to the Java language. Recently I was writing a program revolving around the creation of classes and constructors...my code looks like this:
import java.util.Scanner;
class Money{
     private static int dollars, cents;
     Money(int dollars, int cents){
     Money(int dollars){
     Money(){
     static Money add(Money n,Money n2){
          return (n + n2);
     static Money minus(Money n,Money n2){
          return (n + n2);
     public static boolean equals(int m, int m2){
          if((m == dollars) && (m2 == cents));
               return true;
     public String toString(){
          return ("Dollars = "+ getDollars() + " " + "Cents =" + getCents());
     public static int getDollars(){
          return (dollars);
     public static int getCents(){
          return (cents);
     public static void setDollars(int n){
          dollars = n;
     public static void setCents(int n2){
          cents = n2;
class Program2_5{
     public static void main (String [] a) {
          Scanner kb= new Scanner (System.in);
          System.out.println ("Enter the amount of dollars");
          int d=kb.nextInt();
          System.out.println ("Enter the amount of cents");
          int c=kb.nextInt();
          Money.setDollars(d);
          Money.setCents(c);
          System.out.println (Money.toString());
The main part of my code is just to simply make sure the methods actually work. When i go to compile my code I get three errors revolving around three specific lines.
Error 1= {Operator + cannot be applied to Money, Money}
*static Money add(Money n,Money n2){*+
*     return (n n2);*+
Error 2= {Same as Error 1}
*static Money minus(Money n,Money n2){*+
*     return (n n2);*+
Error 3={non-static method toString() cannot be referenced from a static context}
*public String toString(){*+
*     return ("Dollars = " getDollars() + " " + "Cents =" + getCents());*+
In order to fix Error 3 i tried to place static in front of String toString() but got an error about the Money String toString() cannot override the Object StringtoString()
I have been working with this program for hours on and off and would really appreciate it if someone with more experience could help me...Thank You

I think there are a few things that could help you out. Firstly, amounts are generally not looked at as dollars and cents separately. You can always go back and change it, but I'd code it a bit more like this:
import java.util.Scanner;
public class Money {
private double amount;
public Money() {
    this(0.0);
public Money(double amount) {
    setAmount(amount);
public void setAmount(double amount) {
    this.amount = amount;
public double getAmount() {
    return(amount);
public void add(double amount) {
    setAmount(getAmount()+amount);
public void minus(double amount) {
    setAmount(getAmount()-amount);
public boolean equals(double amount) {
    if (getAmount() == amount)
      return true;
    return false;
public String toString() {
    return ("Amount = "+getAmount());
public static void main (String [] argv) {
    Scanner kb= new Scanner (System.in);
    System.out.println("Enter initial amount");
    double a=kb.nextDouble();
    Money money = new Money(a);
    System.out.println(money.toString());
    System.out.println("Enter amount to add");
    a=kb.nextDouble();
    money.add(a);
    System.out.println(money.toString());
    System.out.println("Enter amount to subtract");
    a=kb.nextDouble();
    money.minus(a);
    System.out.println(money.toString());
    System.out.println("Enter amount to compare");
    a=kb.nextDouble();
    System.out.println(money.equals(a));
}Hope it helps you out.

Help for a beginner in utl_file

Hi,
As I said I have just begun to learn pl/sql and looks like I am having a big trouble with it. I will attach the code I started with I know it does not do much and useful but can someone please help me run it? When I try to run it it gives the compilation error invalid directory path...
CREATE OR REPLACE PROCEDURE encrypt_to_file IS
/* Output variables to hold the result of the query: */
a ALL_OBJECTS.OWNER%TYPE;
b ALL_OBJECTS.OBJECT_NAME%TYPE;
vlocation VARCHAR2(16) := 'OUTPUT';
vopen_mode VARCHAR2(16) := 'w';
F1 UTL_FILE.FILE_TYPE;
/* Cursor declaration: */
CURSOR TCursor IS
SELECT OWNER, OBJECT_NAME
FROM ALL_OBJECTS;
BEGIN
OPEN TCursor;
F1 := utl_file.fopen( vlocation, 'DENEME.TXT', vopen_mode );
LOOP
/* Retrieve each row of the result of the above query
into PL/SQL variables: */
FETCH TCursor INTO a, b;
/* If there are no more rows to fetch, exit the loop: */
EXIT WHEN TCursor%NOTFOUND;
END LOOP;
UTL_FILE.FCLOSE(F1);
/* Free cursor used by the query. */
CLOSE TCursor;
END encrypt_to_file;
/

OK, so someone has created a directory object for you.
What do you mean by "I don t get the error with its last condition as procedure"? Are you saying that you no longer get the error when running your procedure?
Are you looking in C:\Temp on the machine where Oracle is running for the file?
In the code you posted, you are not writing anything to the file. Can you add a UTL_FILE.PUT (or PUT_LINE) to ensure that there is something in the file?

Code bug help for a beginner!!

Ok, I've written this code so far. Everything was fine until I got to the IF condition. When I try compiling it it tells me that the 'a' variable in the IF condition expression may not have been initialised, which I don't really understand as it's been declared at the start of the program and even used fine beforehand in the switch statements.
Any ideas?
Thanks for any help. Here's the code.
import javax.swing.JOptionPane;
public class LetterProgram {
public static void main (String args[]) {
   String pickALet;
   String output;
   char letter;
   int guess;
   int a;
   pickALet = JOptionPane.showInputDialog ("please enter a lower case letter from (a to e)");
   output = "you selected a letter " + pickALet;
   letter = pickALet.charAt(0);
   switch (letter) {
   case 'a':
   a = 1;
   output = "you entered an a";
   break;
   case 'b':
   a = 2;
   output = "you entered a b";
   break;
   case 'c':
   a = 3;
   output = "you entered a c";
   break;
   case 'd':
   a = 4;
   output = "you entered a d";
   break;
   case 'e':
   a = 5;
   output = "you entered an e";
   break;
   default:
   output = "i did not recognise your entry";
   break;
   JOptionPane.showMessageDialog(null, output, "your letter", JOptionPane.INFORMATION_MESSAGE);
   guess =(int)(Math.random()*5 +1 ) ;
   System.out.println(guess);
   if (guess==a)
      System.out.println("The computer guessed the correct letter");
   else
      System.out.println("The computer guessed the letter incorrectly");
   System.exit(0);

It's better to add a default label to the switch; otherwise for most cases you will be setting the value twice, and it makes the intent of 'none of the above' clearer.

Help for a beginner creating a 2d image-processing suite in LabVIEW.

I am a final year student and currently seeking any advice from experienced engineers with regard to my project.
The project is to create a LabVIEW based image-processing suite, which would be able to import 2d arrays of data from microscope, plus other information (scaling, date/time, sample info) and perform the following functions:
Visualisation – 2d & 3d, Cross-section Profile Analysis, Histogram, Fourier Transform, Auto-Correlation, Copy, Print, Save & Export, Colour Palette Edit, Zoom, Manipulate.
Having not used LabView previously, any examples or information you may have would be of extreme use,
Thank you in advance for any help you can give me,

Sam,
Most of these tools are readily available in LabVIEW when you purchase the IMAQ Vision toolkit. You just need to learn how to use them and set them up. In your case, I would strongly recommend starting with Vision Builder. You can learn how to use a number of these tools, and it may actually be sufficient for your project without writing any code. It can generate LabVIEW code as well, so it would get you started on your program.

Help for a beginner please -using iTunes

Using iTunes for the first time, I buy and download an item. It`s a piece of music that lasts 55 mins.OK.The stuff comes down the line, and I can make it play on my scratchy screen-speakers.
I then try to copy it to a DVD with my DVD writer. I`m warned it may take up to an hour. No indication of progress is given. After a few minutes there`s a xylophone-bong. Maybe it means the process failed. Maybe succeeded. I don`t know. No indication of either.The disc won`t play so I suppose I failed.
A make a second try, on to a CD. This time no Burn - button appears on the screen, so I`m stuck straight away. Is Apple stopping me making a second copy, so I have to spend another ten quid downloading the thing again ? A pretty severe penalty for a mistake !
Can anyone put me right, and maybe direct me to an elementary tutorial ?
Eigenblog

Making a DVD only creates a backup copy of a track. It does not create a disk that can be played in any other player. If you want to create a disk that can be played in other players, you need to burn an audio CD, so check your iTunes -> Advanced -> Burning preference and make sure it's set to Audio CD. Then you need to put the track into a playlist. It can be the only track in the playlist, but it must be in a playlist before it will burn.
For more information, this tutorial may help:

Hope this helps.

A help for a beginner

i just downloaded JMF on a windowxp OS ( i also downloaded java2sdkl1.4.2_02 ).
I added the lib and bin directories to the PATH in the systems environment variables and i checked that the jmf.jar and sound.jar are created in the CLASSPATH user environment variables.
My first question : should i add anything else to my environment variables ?
i am trying to make an rtp session between two pcs and transmit audio files between the two terminals.
i followed many methods and all of them failed, but i don't know the reason behind the failure .
first, i opened an rtp session on the receiver side with the ip address of the transmitter and the port and was waiting for data.
on the transmitter side , i have chosen an audio file to transmit by the transmit option at the ip address of the receiver and the same port .
the result was :
when i tried to transmit an mp3 file, the receiver side have this error :
Controller error:
Internal Module com.sun.BasicRendereModule@16aa42e: failed to handle a data format change.
when i tried to transmit a midi file, the transmitter side have this error :
Failed to create processor.
Exception.
Cannot find a processor for : com.sun.media.protocol.file
DataSource@57e787
second method, i transmit the audio file by the transmit option.
on the receiver side, i opened the URL address : rtp:// 192.168.10.10/40000/audio/1/4
192.168.10.10 is the ip address of the transmitter side
40000 the port number same at both sides.
audio 1 is the number of the track.
4 is the value of ttl.
the result is that the receiver opened a player but did not hear anything.
i also tried the methods described at JMFsolutions : AVReceive2/3, AVTransmit2/3 aslo they failed.
Last thing, when i try to add a plugin for the codec or renderer or anything else on the registry editor, i receiver the following error:
Could not add item.
Hope someone will help me to solve the problems.

Any one found out the answer ? I get the same damn error ...
RTP Handler internal error: javax.media.ControllerErrorEvent[s
a.content.unknown.Handler@19616c7,message=Internal module com.
dererModule@f0eed6: failed to handle a data format change!]
thanks in advance for helping me out ...

Printing from ipad - help for a beginner please

I have downloaded the "Print to All.." app into my ipad 1. I have an HP Photosmart Premium wireless printer. How do I print an e-mail?

Have you consulted the Help pages?
http://mobile.eurosmartz.com/help/help_index.html (assuming that's the correct app).
However, if it is the correct app, the second line of the description in the AppStore says:
"if you want to print email, docs, web pages or calendar etc, look at our other app "Print n Share""

and wish to print out a line, which has the sum of these numbers, and the average of them.
any help will be greatly appreciated.

So what's the problem?
How would you do it manually? Write that down in very simple, precise, small steps. Then translate those steps into Java code. Post your best effort and specific questions when you get stuck.

Absolute Beginner needs help

I've had my 30 GB color video iPod for a few hours, and feel totally lost.
I was able to connect it to my iMac, and the computer used iTunes to synch everything.
How do you turn it on or off? How do you stop it from playing music?
How do you set it up, or use the wheel to select stuff?
This is all very basic stuff, and I couldn't find the info in the help files or in this discussion forum.
Am I just plain dense?

To stop the iPod from automatically syncing with iTunes when you connect the iPod to the computer you will need to change some preferences.
Connect the iPod to the computer and then stop the iPod from syncing. While the iPod is still in iTunes i.e is still in the left column (sometimes it ejects the iPod when you stop it from syncing don't ask me why : /)
I will assume that you have the latest iTunes (if not you will eventually need to download it anyway) so all you will have to do is click on the iPod in the left column and click on the "Manually manage music and videos" box. Now you will have to drag songs/videos/playlists to the iPod.
To turn off your iPod simply hold the play button until it sleeps. Then you can put it on hold so it wont turn on accidently.
To select stuff... as in selecting a specific song? then navigate to the prefered song listing (songs or playlists artists etc) using the center button (sorry if this sounds obvious but you did say absolute beginner :P)
To stop a song selection from playing just push previous until you have gone past the first song. there may be easier ways but unless your playing 4000 songs its not very time-consuming
Hope this helps you out a bit look forward to some feedback and quires
This is probably covered in the links provided by b noir but this is just to focus on the specifics of your questions.

Intuos/Photoshop Help for Beginner

Hey There,
I'm an absolute beginner with the Intuos and not much better with Photoshop, so please forgive me if this question is a little basic for this forum. I'm going to be using the Intuous and Photoshop (or maybe Corel Painter) for a research project evaluting a computerized administration of some tests of visual perception and visual memory. I'm looking to create a permanent record of the study subjects' drawing processes, such that I could play back their individual pen-strokes in real-time, and preferably with the option to speed-up, slow down etc. Is this something that would be possibly with Photoshop? I spoke with someone at Wacom who said they were fairly sure that Photoshop or Painter did this, but they weren't sure which one.
Thanks much.

You can keep a text log of every action made in Photoshop but you will not have a record of how the user is drawing with the pen.
I would look into Camtasia which keeps a video record of all activity on the screen. It is used by many professionals to produce tutorials.
