Writing my first program....
Okay my first programming assignment is to write a program that requests an amount of money and will then calculate how many quarters, dimes, nickels and pennies it takes to get that number. I do wanna figure this out by myself, but since im new to JAVA i was wondering if anyone could give me some ideas and/or hints as to maybe where a good place to start is.....
A good way to start is for you to do what the program needs to do, and write down the steps involved.
Assume you start with $1.01
What would you do first?
next?
and so on.
Each statement should consist on only one action.
By the time you finish, you've pretty well outlined what the program needs to do.
Then you can start figuring out wha program instructions are needed.

Can't install itunes. error writing to file program files (x86)\Adobe\gnsk_dsp.dll
I can't update itunes.
During installation it says:
Error while writing in file: Program Files (x68)\Adobe\gnsk_dsp.dll.
Check whether you have the right to open that file.
How can I remove this error?That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards? -

I created my first program-compiling error-help please
hey there
i just wanted my first program in java and here it is below with the eroor when i'm compiling it, i cant understand whats wrong:
public class SquareArea {
public static void main(String[] args); {
float length;
float width;
float SquareArea;
System.out.println ("Please enter length"+ length);
System.out.println ("Please enter width"+ width);
SquareArea= length*width;
System.out.println ("The area of the square is" + SquareArea);
The error is:C:\Documents and Settings\User\Desktop\SquareArea.java:5: missing method body, or declare abstract
public static void main(String[] args); {
^
1 error
Tool completed with exit code 1There shouldn't be a semicolon between the ")" and the "{" near the end of that line.
With that semicolon, you're basically defining an empty, zero-size main method, and then throwing a bunch of garbage after it. That's what the compiler thinks anyway. Remove that semicolon and it should compile OK.
But it won't work super well, because you're not actually getting any input for length and width. It's just going to output this:
Please enter length0
Please enter width0
The area of the square is0 -

I want to program in java so badly but I am trying to get my environment set so that I can take off. To compile my first program has been a disaster!!
This is my path:

use String instead of string. and System.out instead of system.out

How to execute the first program without using SUBMIT and RETURN
Hi Experts,
My requirement is , I need to select thet value from VA02 at runtime and need to pass that value to VF01 transaction and press save then it creates proforma document.The created document we can see in VA02 by clicking on document flow.
My program is processed through OUTPUT TYPE.
To get this functionality i written coding like this.
1) i am selecting the value at runtime from VA02 using FORM ROUTINE.Now iam passing this selected value to VF01 for
genarate proforma document using BDC.Here the problem is,first time when i am selecting the value form VA02 at runtime it is in open status,now my BDC code need to update the value in VA02 only.so locking problem occurres the document is not getting updated.
To overcome this problem i have done changes like this......
2) i splited my program into two parts, that is into two programs.
a) In first program i am only selecting the value form VA02 at runtime using FORM ROUTINE and in this program i have written SUBMIT statement to call another program there my BDC code will create documet and update in VA02,upto here everything is doing fine,
But here again the problem is when i process OUTPUT type my program is triggering and giving correct result but the status is not changing form YELLOW to GREEN.Why means when SUBMIT statement trigger, control is going to second program and creating a new document,but not coming to first program so the status is not changing as the first prohram is still processing. .If i write RETURN along with SUBMIT the VA02 is in open STATUS only, till control comes to first program.so it will not uodate document in VA02.
If i execute all line in my program status will automatically change from YELLOW to GREEN how to acheive this
please suggest me the solution.I would do 2 things:
1) be sure to do a COMMIT WORK AND WAIT
2) refresh your display in calling program
the point 2) can be done by submitting the program again (or the transaction) with the same parameters -

My First Program, Seeking Advice
Hello all!
This is my first program attempt with Visual Studio 2013 Express and I don't have hardly any experience in programming to begin with...so bare with me. I have this idea for a Digital Communications Board. You know like the ones that are make of cork board
that have a million things attached to it and its all over the place? Ya that mess. I have several ideas for this concept which, if given enough help, I will go into later. But basically, I want to be able to have a program or app that lets you assign categories
for certain things that can be displayed in a work setting. Categories like Schedule, Announcements, and other things that you would want to add as you think of them. so I imagine this board starting out with a few that can be edited.
The main aspect of this program is to be able to upload any screenshot or picture or pdf file that is available and present it in a fashion that is organized. So if we just focus on the Schedule tab that I mentioned already I can probably explain it better.
The way I will personally use this is to display employee schedules through the addition of a picture or file taken from my company's system (not a data retrieval, just simple manual entry). Later down the road I will attempt to make it so that the Schedule's
for each employee can be entered manually so that there are simple layouts and no excess material to fill up the space.
So with this idea in mind what would be my first steps? I know I need the following things:
1. I want to be able to have a minimum of 3 tabs displaying the name of the display that would come from it. for example, If i click the button/tab that says "Schedule" then that tab would expand or present the content that IS the schedule for
the employee's or what has been set by the user to be displayed there.
2. I want to be able to expand the number of tabs with ease. Like a typical "+" button that would obviously add another tab that can be set up for another purpose while at the same time it is formatted to space itself on the main page with
the other tabs.
I know this is a lot at one time but I really just want to get some constructive feedback and if someone is awesome enough to actually write code for me then please please please put comments in the code so I can understand!
I appreciate any and all feedback!

2- PL section
3- Both in communication.
I just want a minimal design to get into.
Have you tried to just Google "zedboard tutorial" there are tons of tutorials out there. Go to zedboard.org support and look around. You can find some here: Zedboard Tutorials, In the tutorials is a step by step guild to build a simple PS/PL design that interacts with the switches and leds. If I remember there are two main tutorials, one is bare-metal (don't need to boot Linux) and the other requires Linux up and running via the SD interface.

and the second issue is:
It is not recognizing the date format..it is recognizing the date in first row only......

I have a 27" iMac 3.06 GHz Intel Core 2 Duo. I use Mail for my email. Just in the past 2 -3 months, if I'm writing an email while another one is coming in to the inbox, the program freezes, the spinning colour ball appears and I can't continue typing for 5 seconds or more. I get and write a lot of emails so it's frustrating.
I've also noticed that sending messages is taking longer than it used to. The program spins its wheels for a few seconds before sending. Definitely noticeably longer than prior to this situation. Any ideas anyone?Hello,

I just started taking a class in Flash CS4 and I have a basic program that I'm suppose to develop for my first project. My problem is that I'm not good at programming yet so I was wondering if anyone is able to help me out. Here is what I'm suppose to do.
Use flash CS3 to create a mini marble game. It should have the following elements:
• a) The first scene should have a single button labeled "start game", placed at the exact center of an 800*600 pixel screen. A simple background image containing a polka dot pattern should fill the background layer for this intro screen.
• b) When the start button is pressed, the game should show a new screen with a solid color background (which may be white). Two marbles, represented by filled circles (80 pixels of radius or 80 by 80 pixel bounding box) of two different colors should appear. The first marble should appear at the exact center of the stage, the second marble at either a random location (extra credit for this) or one of four possible locations OTHER than the area allocated for the first marble.
• c) Using the mouse or any keystroke, the player should be able to "start" the second marble in the direction of the first at a constant speed of 24 pixels per second (use an event handler and the Enter_Frame event, as well as a 12 fps speed for the movieclip, to establish the speed of the marble).
• d) When the first marble collides with the second, it should stop it's motion, and the second marble should start moving at the same speed in the same direction than the first one until it leaves the screen.
• e) Display a "Game Over" sign, when the second marble has left the screen.
• f) Publish the movie, and upload both the fla and swf here.
I finish the a) section but I don't know what to do with the rest. Here is my file.
http://rapidshare.com/files/360378296/Project1.flause some actionscript to code your start button to move to a new frame where your two marbles are on stage. then apply actionscript to the 2nd marble so when it's clicked or a key is pressed you start a loop that moves that 2nd marble towards the center marble. when the two collide (use hitTest() ), stop the 2nd marble and start moving the 1st marble.

[perl] Writing my first module (IPTables::Rule); Looking for feedback
Well pretty much as the subject says... I've been hacking away with perl for a while, but this is the first time I've tried writing a module.
I think (hope) I'm on the right track in terms of doing it the "right" way (or one of the X "right" ways perl lets you!).
If you're bored and have time to have a glance over and tell me how I'm doing, that would be great

The only practical reason to use it now is to disable argument checking which has been previously enforced by prototypes.

I was actually aware the ampersands are not required, but I like them... They're just a little hint when skimming code that it's a function... Just like $, @ or % on variables. Having a Google around, I didn't actually know there was a difference between using it and not using it, so I'm removed them too. I'll get used to it
