Need help with saving my project
When I try to export and save my project, iMovie answers that I need more storage space to go on and that I need to end and restart the program. What can I do to save my project? There is lots of work in it. Thank you.
If iMovie is only preventing you from sharing/exporting your movie, your project itself should still be OK.
If you have everything on your internal drive it is probably getting too full (you can check with finder). You need to free up some space or get an external hard drive. An external drive is almost essential if you are going to do a lot of video work since file are so large.

Need help with saving data and keeping table history for one BP
Hi all
I need help with this one ,
Scenario:
When adding a new vendor on the system the vendor is suppose to have a tax clearance certificate and it has an expiry date, so after the certificate has expired a new one is submitted by the vendor.
So i need to know how to have SBO fullfil this requirement ?
Hope it's clear .
Thanks
BonganiHi
I don't have a problem with the query that I know I've got to write , the problem is saving the tax clearance certificate and along side it , its the expiry date.
I'm using South African localization.

Need help with lost iMovie project.
I was creating an iMovie project for school and needed to save it on a USB, so I clicked on 'Export Movie' from the 'Share' options menu in iMovie. I chose the type I wanted it saved in (viewing for computers) and then a smaller screen in iMovie popped up saying it was exporting the movie, or something like that. It took about a good 30 minutes and my project was a 7 minute movie with film clips, music, transitions, ect. I exported this project to my USB but when it finished it wasn't on there and when I finally found it on the Mac somewhere, I went to drag it into my USB but it said it was full. I then dragged the project onto my desktop and tried to open it to see if it worked. When I did the iMovie icon jumped once and stopped. I clicked on iMovie and it was still there in the projects screen. I then decided to close iMovie and open the project again from my desktop to see if it would play like a normal movie but once I clicked it the iMovie icon jumped again, opened but my project that I was trying to open was not there anymore and wouldn't open from my desktop file. I cannot open it at all and view it, it has been lost from my iMovie. Is there a way that I can get it back? Really need some help with this.
What version of iMovie are you using?

I need help with my hangman project
I'm working on a project where we are developing a text based version of the game hangman. For every project we add a new piece to the game. Well for my project i have to test for a loser and winner for the game and take away a piece of the game when the user guesses incorrectly. these are the instrcutions given by my professor:
This semester we will develop a text based version of the Game Hangman. In each project we will add a new a piece to the game. In project 4 you will declare the 'figure', 'disp', and 'soln' arrays to be attributes of the class P4. However do not create the space for the arrays until main (declaration and creation on separate lines). If the user enters an incorrect guess, remove a piece of the figure, starting with the right leg (looking at the figure on the screen, the backslash is the right leg) and following this order: the left leg (forward slash), the right arm (the dash or minus sign), the left arm (the dash or minus sign), the body (vertical bar), and finally the head (capital O).
Not only will you need to check for a winner, but now you will also check to see if all the parts of the figure have been removed, checking to see if the user has lost. If the user has lost, print an error message and end the program. You are required to complete the following operations using for loops:
intializing appropriate (possible) variables, testing to see if the user has guessed the correct solution, testing to see if the user has guessed a correct letter in the solution, and determining / removing the next appropriate part of the figure. All other parts of the program will work as before.
Declare figure, disp, and soln arrays as attributes of the class
Creation of the arrays will remain inside of main
Delete figure parts
Check for loss (all parts removed)
Implement for loops
Init of appropriate arrays
Test for winner
Test if guess is part of the solution
Removal of correct position from figure
Output must be

Well i have worked on this and come up with this so far and am having great dificulty as to i am struggling with this class. the beginning is just what i was suppose to comment out. We are suppose to jave for loops for anything that can be put into a for loop also.

If anyone cann please help me i would greatly appreciate it. I have an exam coming up on wednesday also so i really need to understand this material and see where my mistakes are. If anyoone knows how to delete the parts of the hangman figure one by one each time user guessesincorrectly i would appreciate it greatly. Any other help in solving this program would be great help. thanks.Hi thanks for responding. Well to answer some of your questions. The professors instructions are the first 2 paragraphs of my post up until the ende of the output which is You lose!. I have to have the same output as the professor stated which is testing for a winner and loser. Yes the program under the output is what i have written so far. This is the 3rd project and in each we add a little piece to the game. I have no errors when i run the program my problem is when it runs it just prints the hangman figure, disp and then asks user ot enter a letter. Well once i enter a letter it just prints that letter to the screen and the prgram ends.
As far as the removal of the parts. the solution is TEST. When the user enters a letter lets say Tthen the figure should display again with the disp and filled in solution with T. Then ask for a letter again till user has won and TEST has been guessed correctly. Well then we have to test for a loser. So lets the user enters a R, well then the right leg of the hangman figure should be blank indicating a D the other leg will be blank until the parts are removed and then You lose will be printed to the screen.
For the program i am suppose to use a FOR LOOPto test for a winner, to remove the parts one at a time, and to see if the parts have been removed if the user guesses incorrectly.
so as u can see in what i have come up with so far i have done this to test for a winner and loser:
//declaring a string variable
String data = " ";
// call the readString method
data = readString();
//retrieves the character at position zero
char temp;
temp=data.charAt(0);
int h;
for(h=0;h<4;h++)
if(temp==soln[h])
disp[h]=soln[h];
return;
if(disp[h]==soln[h])
System.out.println("You Win");
else
for(h=0;h<6;h++)
if(temp!=soln[h])
figure[h] = ' ';
return;
if(disp[h]!=soln[h])
System.out.println("You Lose");
Obviously i have not writtern the for loops to do what is been asked to have the proper output. the first for loop i am trying to say if the user input is equal to the soln thencontinue till all 4 disp are guessed correctly and if all the disp=soln then the scrren prints you win.
then for the incorrect guesses i figured if the user input does not equal the soln then to leave a blank for the right leg and so on so i have a blank space for the figure as stated
:for(h=0;h<6;h++)
if(temp!=soln[h])
figure[h] = ' ';
well this doesnt work and im not getting the output i wanted and am very confused about what to do. I tried reading my book and have been trying to figure this out all night but i am unable to. I'm going to try for another hr then head to bed lol its 4am. thanks for your help. Sorry about posting in two different message boards. I wont' do it again. thanks again, anita -
i,ve created frame with a JTable, and add new button.
every time i run project table gets empty, of course, that is normal, but i would like that when i tipe something in my table and press button, things i wrote in table get saved. lets say that the variable name of JTable is "table" and name of button "save". i'm not expert in java programing but i really need this code. could someone please be so generous and wrote that code for me? i need it till tomorrow :SWhat you need is Serialization.
I did a quick google search and found this:
http://java.sun.com/developer/technicalArticles/Programming/serialization/
It basically allows you to save your object and load it later.
You could also save your stuff in plain text. Follow this tutorial to learn how, This is maybe a bit easier if you don't know what objects are.
http://java.sun.com/docs/books/tutorial/essential/io/index.html -
I recently started studying in IT at college, and I think I have the basics in Java programming, however we haven't
been taught how to save data in our apps, so everytime i close my app, I lose all changes.
I went through Sun's IO tutorial, as well as a few tutorials online and I made a small application to practice saving my
Objects, however I can't seem to get it to work. I was hoping someone could look at my code and tell me what seems
to be my problem.
There are 3 classes in my project. The Base class makes a List that holds objects of type Person. the UIPerson class
has 3 buttons (Add, Save, Load) and a JList. When clicking on Add, it adds a new Person in the base and is shown in
the JList. The saving and loading is what I have trouble with.
UIPerson :
public class UIPerson extends JFrame implements Serializable{
private JFrame jFrame = null;
private JPanel jContentPane = null;
private JButton jbAdd = null;
private JButton jbSave = null;
private JButton jbLoad = null;
private JList list = null;

jContentPane.setLayout(null);
jbAdd = new JButton();

jbAdd.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
String Name, famName;
Name = JOptionPane.showInputDialog("Enter Name", null);
famName = JOptionPane.showInputDialog("Enter Family Name", null);
base.addPerson(new Person(Name, famName));
list.setListData(base.listPerson());
jbSave = new JButton();
jbSave.setBounds(new Rectangle(19, 106, 69, 34));

return tab;
public Person getPerson(Person person){
ListIterator<Person> iterator = list.listIterator();
Person current = null;
while (iterator.hasNext()){
current = iterator.next();
if (current.equals(person))
return current;
return null;
}Person :

this.name = name;
this.familyName = familyName;
public String getName(){
return name;
public String getFamilyName(){
return familyName;
public String toString(){
return name + " " + familyName;
}I'd appreciate any help that could be given.My probelm is with my save/load funtions only, sorry for the extra code. Everytime i press on save or load, they
throw an IOException. Heres the code I specifically wanted viewed to know if there are any mistakes in it.
Save Button :
jbSave.addActionListener(new java.awt.event.ActionListener(){
public void actionPerformed(java.awt.event.ActionEvent e){
try{
FileOutputStream fos = new FileOutputStream("temp.dat");

catch(FileNotFoundException ex){
System.out.println("(Save)File Not Found Exception");
catch(IOException ex){
System.out.println("(Save)IOException");
});Load Button :
jbLoad.addActionListener(new java.awt.event.ActionListener(){

I have an Ipad and was saving movies on it until it let me know that I was running out of space. I went in and purchased additional space on Icloud but now cannot figure out how to get things moved over to Icloud...help?!
iCloud storage space are meant mainly for backup purposes. You can't move your data from iPad to iCloud like other cloud storage like Dropbox or Box.net.
You need to clear up space from your iPad.

Need help with saving file for printer
I am using Acrobat 9. I have a document with four pages. I need to save it in two files-- one file with p. 4 and 1 side by side to print on 11 x 17 paper, and the other file with p. 2 and 3 the same. The person printing does not have Acrobat so the pdf itself has to be formatted this way so they can print it. I can rearrange the pages, delete pages, and so forth, but I cannot get them to display side by side except in a "view" option.
Thanks for any help.Thanks could remember that for nothing

What do I need to do to complete this code?OK, yeah. Change the Product constructor so that it takes scalar values (as opposed to arrays) -- a single int for units in stock, and single String for name, etc.
Then you can create multiple objects of that class, one for each CD or whatever.
It makes sense to hardcode values in the ProductTest class, but not really in the Product class. Your ProductTest class is almost there. You know how in the main method you create a single Product object with those arrays? Change it so that you have a loop. Loop through the prices, album names, etc., and create a Product for each set of values. Then put the Product objects in an array, or better yet (and if you've covered it in class) into a Collection like a java.util.HashSet or a java.util.ArrayList.
You said you wanted to make it take values from user input, rather than hardcoded lists. Once you've made the above change, move on to doing that. You can read user input with a java.util.Scanner. Or you can use a java.io.BufferedReader. Did the prof say to use one particular method or another? -
Need help with saving pdf form
I created a quote form for our sales people to fill out and email to their customers. I can't figure out how to set it up so that after they fill out the form it can be saved with the field locked so they cant be changed. Is that even a possibility? I've been working on this for 2 days and just keep going in circles with it.
You can set up the form so that the fields get set to read-only after the salesman completes the form but before sending it out. This idea is discussed in this topic: http://forums.adobe.com/message/3314067#3314067

Need help with an array project please =)
I'm having trouble figuring out where to start. My project is to create an applet that accepts 20 numbers from a text field one by one and adds them to an array. The numbers have to be between 10 and 50 or else the applet shouldn't include them in the 20 but duplicates should be included in the 20. The applet then has to display all the numbers except for duplicates. example:
user inputs:
10,11,12,13,14,15,16,16,16,17,18,19,20,20,20,21,23,24,25,26
applet detects that 20 numbers have been entered and displays them exluding duplicates:
10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24, 25, 26
If the user imputs a number like 72 I need to make it alert them that the number was not in the 10-50 range and not add that number to the total 20.
I'm not asking anyone to do this for me, I'm just asking for tips on where to get a good start.
Thanks!//i haven't tryed that code, and it might not work
// anyhow, just in case, i'll also say that this is not an applet
public class NoDublicates {
public static void main(String[] args) {
if (args.length < 20) {
System.out.println("usage:\njava NoDublicates "
+ "<and 20 space separated numbers from 10 to 50 here>");
System.exit(1);
byte[] nums = new byte[args.length];
int i = 0;
for (int j = 0; j < args.length; j++) {
try {
int temp = Integer.parseInt(args[j]);
if (temp <= 50 && temp >= 10) {
nums[i++] = temp;
} catch (NumberFormatException nfe) {
// very bad exception, i think i'll ignore it
if (i != 20) {
System.out.println("it seems that i didn't get exactly 20 "
+ "parseable numbers as arguments, let's exit now.");
System.exit(1);
java.util.Arrays.sort(nums);
int old = 0;
for (int j = 0; j < 20; j++) {
if (nums[j] != old) {
System.out.print(nums[j] + " ");
old = nums[j];

Need help with saving Premiere files to work with any update
Hey everybody,
I've been editing with Premiere for a while now and I haven't really had too many issues until now. I live on campus at school and they just opened up a new Library with extensive Mac Pro editing stations, some with 4K monitors! The problem is that the school is not updating the software. So I am running the latest version on my Macbook Pro, but when I try and open the files on the library computers, it tells me something like, "Cannot open file because file was saved on a newer version." Now I know it seems obvious that I should just stick to my computer, but it's nice having a much faster editing station with 27"+ screens. Because the library is so new, they are having trouble keeping up with all the updates and they don't seem to plan on updating them except every semester. So, are there any workarounds? Can I save my files as a more multi-platform file?I would take your computer back to the earlier version the college uses, there are workarounds to go back versions but they are not perfect.

I need help with saving all of the photos and videos on my iPhone.
When I access the screen that has Photos, Shared, and Albums and I click on Photos, there are more photos there than the phone is counting that
I have on my iPhone. How do I save all those photos or put them onto my computer? I have saved the photos it will let me but I cannot access the photos from more than 2 years ago. Also my phone says I have 43 videos but only 10 save.
Also, when I upgrade and switch to a newer iPhone, will I see all those photos from the whole history of my phone, will I see all 43 videos, and all my iMessages and SMSs?
Thank you.Hi Sharon,
The best thing for you to do is 2 things.
When you purchase a new device(whether it be a iPhone, iPod or iPad)
1) Perform a full backup of your old device via iTunes. This will save contacts, calendars, photos, text messages, emails, apps in folders how you left them, music, videos, podcasts etc. Note it won't import your photos unless you tell it to.
1.1) When you get your new device it will ask whether to set up as a new device or from a backup, select from backup and your new phone will look and be exactly the same as your old one, same settings etc.
2)[optional] I personally like to backup my photos to iPhoto on my mac once a month. When it reaches the end of the library it asks whether to delete originals or not. If you hit no it doesn't change the photos on your device and you have a copy in your iTunes library. This is handy if you want to use photos from your phone on your mac.
