A very simple, very stupid question

When I do screen grabs (shiftctrl+apple4) where do those pictures go??? I can't find them anywhere though I do hear the "camera snap" sound. Thank you for any help you can provide.

Screen shots are saved as .tiff files on the desktop. If you want to put the screen shot in the Clipboard, rather than create a file, hold down the Control key when you press the other keys. You can then paste the picture into a document.
You can also take pictures of the screen using the Grab application (in the Utilities folder).
(And that was not a stupid question!)

Very simple and quick question about Arrays

Hi,
I have the following code to produce a student grades provessing system. I have got it to store data in the array, i just cant figure out how to add the integers from the row to produce a total. Thats all I want to do create a total from the 6 marks and add a percentage.
Any help would be greatly appreciated.
-------------CODE BELOW----------------------
import java.util.*;
public class newstudent1_2
public static void main (String[]args)
System.out.println ("-----------------------------------------------"); //Decorative border to make the welcome message stand out
System.out.println (" Welcome to Student Exam Mark Software 1.2"); //Simple welcome message
System.out.println ("-----------------------------------------------");
int [][] mark;
int total_mark;
int num_students;
int num_questions = 9;
Scanner kybd = new Scanner(System.in);
System.out.println("How many students?");
num_students =kybd.nextInt();
mark = new int[num_students][num_questions] ;
for (int i=0; i<num_students; i++)
System.out.println("Enter the Students ID");
String student_id;
student_id =kybd.next();
System.out.println("Student "+i);
for( int j=1; j<num_questions; j++)
System.out.println("Please enter a mark for question "+j);
mark[i][j]=kybd.nextInt();
System.out.print("id mark1 mark2 mark3 mark4 mark5 mark6 mark7 mark8");
//This section prints the array data into a table
System.out.println();
for (int i=0; i<num_students; i++)
for( int j=0; j<num_questions; j++)
System.out.print(mark[i][j]+"\t"); //the \t is used to add spaces inbetween the output table

Thanks.

I had to do this same sort of thing for a school assignment but i didnt use an array.
import java.text.DecimalFormat;
import TurtleGraphics.KeyboardReader;
public class grade_avg
     public static void main(String[] args)
          int grade, total = 0, count = 0;
          double avg = 0.0;
          KeyboardReader reader = new KeyboardReader();
          DecimalFormat df = new DecimalFormat("0.00");
     for (;;)
               grade = reader.readInt("Please enter a grade: ");
          if (grade > 0)
                    total = total + grade;
                    count ++;
          if (grade == 0)
                    avg = total / count;
                    System.out.println("The average is: " + df.format(avg));
                    System.exit(0);
}output looks like:
Please enter a grade: 100
Please enter a grade: 50
Please enter a grade: 0
The average is: 75.00

Very very simple method return question

Using a UML tool, the following code has been generated for a method called getScores.
     //getScores
    public String[] getScores(int nCount)
        //your code goes here
        return null;
     }Can I just clarify what this method is returning here using the parameter nCount - a complete String array or just a position in the array?
And once i've put some code in the method body, i presume the return statement will no longer be null, but either the array or position in the array?

Can I just clarify what this method is returning here
using the parameter nCount - a complete String array
or just a position in the array?It is return an array of Strings.

Very simple iTunes match question

So if I physically unsync my music from my iPad can I still listen to it on said iPad through the cloud as long as I have an Internet connection? (I obviously have an iTunes match account)

Don't have an iPad but that's what I've done on my MacBook. Better yet, items that I forgot about getting through iTunes years ago are fully accesible without adding any bits to my cramped hard drive. And they all play happily through Apple TV, pumped through the stereo.
Now I'm trying to figure out how to track my recently played items that are recently played through the cloud. I have a lot of new music that I'm playing at random though Apple TV and I'd like to make notes of the highlights.

Thanks,

Slava,
Two things:
(1) you need to change this line:
var cChildren:Array = bChildren.getChildren();
To this:
var cChildren:Array = bChildren
.getChildren();
Now, when you click the button, it should report the three
text inputs on the visible tab. If you click on tab 3, it should
report the 3 tabs on tab 3 *and* the 3 tabs on tab 1. Basically, it
will only alert the text input children *after* you have clicked on
a tab and the tab's contents have been created.
(2) If you want to create all tabs at once when the app is
loaded, change this:
<mx:TabNavigator id="tnav" width="540" height="170" y="45"
x="29">
to this:
<mx:TabNavigator id="tnav" width="540" height="170" y="45"
x="29" creationPolicy="all">
Now, when you launch your applicaton, it should display an
alert for each TextInput control on each tab, without having to
click on each tab.
Hope that helps,
Peter

Simple Crop tool question... how do I save the crop section?

Hi,
I have a very simple crop tool question. I'm a photoshop girl usually... so Illustrator is new to me. When I select the crop section I want... how do I save it?... if I select another tool in the tool panel, the crop section disappears and I can't get it back when I re-select Crop tool. If I select Save as... it saves the whole document...and not just my crop section.
Like I said, simple question...but I just don't know the secret to the Illustrator crop tool.
Thanks!

Either press the Tab key or F key.

Very simple question, how do you configure windows 8.1 to use a SF card as the default install location for software applications?

Very simple question, how do you configure windows 8.1 to use a SD card / external drive as the default install location for software applications? Primarily interested in apps installed from the windows store. This should be available in the settings

The registry method does not work with 8.1. I found this out the hard way. Doing it on 8.1 will leave you reinstalling the OS if you didn't do a SRP beforehand.

A very very very simple question

Hi guys,
I have a very simple question and standard but I cant find anywhere...
I have two dateTime variables, i need to calculate difference between this dates in days, thats it.
I tried all functions and tried without success a Java Embed task but I couldnt retrieve this objects as java.util.Date so I couldnt calculate exactly the difference in days like this pure java code:
(dataVencimento.getTime() - dataReferencia.getTime()) / 86400000L)
can you help me this?

Hi Jose
Just see if these alternate approaches works. I know there may be lot like this and you may be lucky to find out simple out of box solution itself. If you want to solve this issue and move ahead, gives these approaches a shot.
1. Create a very simple standalone WebService that takes 2 input date elements (can be of Date type or String type. If string type, convert to date in your java code). Create a simple operation like getDaysBetween(firstDate, secondDate). In the generated webservice impl class, use the java code apis (refer earlier link for usage), and get the difference. Return this value. NOW, invoke this WebService in your BPEL Process, and pass your 2 inputs (if the bpel payload elemetns are date object or string objects of date), and get output, and then use this output in your continuing bpel process.
2. This approach, I did a long back. When we insert any expression using XPath, in that editor window on bottom right side, we see many categories and for each category we see list of functions we can use, like for String, we can use concat etc. I vaguely remember reading somewhere, that we can add our own custom functions also in this section. So explore this direction and see if you can add your own function and then use that fucntion with your 2 input dates.
I have not given solution to your problem, but may be these directions can help you move ahead. Or something along these lines.
Thanks

A very simple question..Very Urgent

HI,
I have a very simple question.I am able to set up the client authentication as well as server authentication. Now do i need to authenticate (both server as well as client auth.) for every request i send to the server on https...i think it should be like that it should authenticate only for the first time and for the next upcoming requests in same session should not require any server or client authentication.. i think as it happens in browsers..
what is the fact actually??..can somebody put some light...right now in my case it is authenticating for every requests..
This is what i have done..
/****constructor part********/
// and tm are arrays of keymanagers and trustmanagers for client keystore and truststore
sslContext.init(km, tm, null);
HttpsURLConnection.setDefaultSSLSocketFactory(ssf);
HttpsURLConnection.setDefaultHostnameVerifier(new MYHostNameVerifier());
/****Method to send the request and response*********/
urlConn = (HttpsURLConnection)url.openConnection();
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
OutputStream os = urlConn.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(someobject);
oos.flush();
InputStream is1 = urlConn.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is1);
SomeObject retObj = null;
retObj = (SomeObject)ois.readObject();
ois.close();
System.out.println("Get String>>>>> "+retObj.getString());
I am creating the object of this class..and calling the method again and again for sending requests and response..so i think handshake everytime i call the method...what i want is that handshake should happen for the first time and for the next requests no handshake or certificates should be checked or processed..
is it possible ..how..what i need to do for that..
please help me in this..

2.If I only know the EJB interfaces,that means the EJB module is writed by other programer.I want to know how I can write the client program.How can I call EJB module's method writed by other programer.Could you give me a simple example?

HT4753 I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

It's actually even easier than using Save As to see the full path to the currently open document. Just do a "Secondary click" on the document title in its window's title bar.
Like you, I relied upon Save As my whole life to check a file's location and considered it a must-have capability. Turns out it's even faster to use the single-click method to reveal the full path to the open document. It displays the entire path to the current document starting from the level of your Mac, and works for files stored on drives as well as iCloud.
If you're not sure how to do a secondary click, go into System Preferences, select Trackpad, Point & Click to find the current preference for secondary click on your Mac. If you happen to have a mouse with more than one button, it's probably the right button. As a trackpad user, I check the box to "Click or tap with two fingers," so a simple two finger tap on the title of an open document reveals its full path. This feature actually has been around for a very long time.
Note that this is not the same thing as the Autosave and Versions menu, which is exposed using a little drop down triangle to the right of the title. There is no visual clue for the presence of this feature - you just have to know it's there, probably because this feature goes all the way back to pre-OS X days.

Very Simple C question - reading input parameters/flags... [SOLVED]

This is an extremely simple question. Please forgive me for being a noob. I am writing an application in C (with GCC) called GAPE and need to be able to pass it parameters through a shell script (/usr/bin/gape) that can determine how it runs. To start with easy stuff, I want the end-user to be able to type "gape -V" to output the version of the program. How do I do that? I understand that I need to put the shell script in /usr/bin...where should I put the actual gcc-compiled gape application? Or do I even need a shell script? Can I just put the GAPE binary in /usr/bin and pass parameters to it directly? If so, how do I do that in C? Any help is greatly appreciated.

A very simple program that prints the parameters
And yes, you can put the program in /usr/bin/ without a shellscript
