This is just odd, plz help
Well I have a 2gb ipod nano. Recently I added 2 CDs to my library then went to update ipod to add them to my ipod. IT said it wouldnt fit and asked if I wanted to make a selected playlist of songs, I hit yes to see what it was then I just hit clear playlist. Well then whenever I tried to update I kept getting a pop that said " Cant update because playlist no longer exsist". So I thought to just completely reinstall itunes and upload my music(yes a pain) it still doesnt really update its blank under ipod list but at that little bottom bar where it says how much is on there some it is filled and it says there's some music on there yet it doesnt show up. Im really not sure how to figure it how so I came here, plz help me!!!!
If you have more than 2GB of music, it won't all fit on your nano. iTunes will create a regular playlist with random samplings of your music until it has enough to fill the iPod, and then set the iPod up to only sync with that playlist. You can either use that playlist to manage what is on your iPod, or build playlists of your own. Or you can start managing the music on your iPod manually.
Sounds like you didn't clear the playlist that iTunes created, you deleted it. You got the error message because you didn't update the iPod preferences to give it a new playlist to sync with.
I use Smart Playlists to manage the music on my iPod. It randomly selects from music that hasn't been played in the last few months. That way every time I sync, music I've just heard goes away, and music I haven't heard in a while gets loaded.

Really need help on how to write this program some 1 plz help me out here.
i am new to java and i confused on how to be writing this program.
i have completed the Part 1 but i am stuck on Part 2 & 3 so it would would be really great if any 1 could help me out on how to write the program.
Part I
An algorithm describes how a problem is solved in terms of the actions to be executed, and it specifies the order in which the actions should be executed. An algorithm must be detailed enough so that you can "walk" through the algorithm with test data. This means the algorithm must include all the necessary calculations.
Here is an algorithm that calculates the cost of a rectangular window. The
total cost of a window is based on two prices; the cost of the glass plus the cost of the metal frame around the glass. The glass is 50 cents per
square inch (area) and the metal frame is 75 cents per inch (perimeter).
The length and width of the window will be entered by the user. The
output of the program should be the length and width (entered by the user)
and the total cost of the window.
FORMULAS:
area = length times width perimeter = 2 times (length plus width)
Here is the corresponding algorithm:
read in the length of the window in inches
read in the width of the window in inches
compute the area
compute the cost of the glass (area times 50 cents)
compute the perimeter
compute the cost of the frame (perimeter times 75 cents)
compute the total cost of the window (cost of glass plus cost of frame)
display the length, width and total cost
The next step would be to "desk check" the algorithm. First you would need to make up the "test data". For this algorithm, the test data would involve making up a length and a width, and then calculating the cost of the window based on those values. The results are computing by hand or using a calculator. The results of your test data are always calculated before translating your algorithm into a programming language. Here is an example of the test data for the problem given:
length = 10
width = 20
area = 200, glass cost= 100.00 (area times 50 cents)
perimeter = 60, frame cost = 45.00 (perimeter times 75 cents)
total cost =145.00
Once the test data is chosen, you should "walk" through the algorithm using the test data to see if the algorithm produces the same answers that you obtained from your calculations.
If the results are the same, then you would begin translating your algorithm into a programming language. If the results are not the same, then you would attempt to find out what part of the algorithm is incorrect and correct it. It is also
necessary to re-check your hand calculations.
Each time you revise your algorithm, you should walk through it with your test data again. You keep revising your algorithm until it produces the same answers as your test data.
?Now write and submit a Java program that will calculate the cost of a rectangular window according to the algorithm explained. Be sure to prompt for input and label your output.?
Part II
Write, compile and execute a Java program that displays the following prompts:
Enter an integer.
Enter a second integer
Enter a third integer.
Enter a fourth integer.
After each prompt is displayed, your program should use the nextint method of the Scanner class to accept a number from the keyboard for the displayed
prompt. After the fourth integer has been entered, your program should calculate and display the average of the four integers and the value of the first integer entered raised to the power of the second integer entered. The average and result of raising to a power should be included in an appropriate messages
(labels).
Sample Test Data:
Set 1: 100 100 100 100
Set 2: 100 0 100 0
Be sure to write an algorithm first before attempting to write the Java code. Walk through your algorithm with test data to be sure it works as anticipated.
Part III
Repeat Part lI but only calculate the average, not the power. This time, make sure to use the same variable name, number, for each of the four numbers input. Also use the variable sum for the sum of the numbers. (Hint: To do this, you may use the statement sum = sum + number after each number is read.)
For Part 1 this is what i got
import java.util.Scanner;
public class Window
public static void main(String[] args)
double length, width, glass_cost, perimeter, frame_cost, area, total;
Scanner keyboard = new Scanner (System.in);
System.out.println("Enter the length of the window in inches");
length = keyboard.nextInt();
System.out.println("Enter the width of the window in inches");
width = keyboard.nextInt();
area = length * width;
glass_cost = area * .5;
perimeter = 2 * (length + width);
frame_cost = perimeter * .75;
total = glass_cost + frame_cost;
System.out.println("The Length of the window is " + length + "inches");
System.out.println("The Width of the window is " + length + "inches");
System.out.println("The total cost of the window is $ " + total);
Enter the length of the window in inches
5
Enter the width of the window in inches
8
The Length of the window is 5.0inches
The Width of the window is 5.0inches
The total cost of the window is $ 39.5
Press any key to continue . . .

One bit of advice: Nobody here takes kindly to lazy, stupid students who are just trying to con somebody into doing their homework for them. If that's you, better have your asbestos underpants on.

In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following:
/Library/Little Snitch

If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot.

Plz refer the below code using this code I m trying to decrypt XLS file using pass phrase.
I m using the same pass phrase which was used @ the time of encryption.
But the problem I m facing is that the file was encrypted in DOT NET_ using padding scheme FIPS81 and there impelmentation of FIPS81 is not available in JAVA so that it gives exception at the time of decryption which is given below
Exception : javax.crypto.BadPaddingException: Given final block not properly padded
I urgently need the solution of this problem so somebody plz help me to find the solution of this problem.....Ur reply would be appriciated.....!!
The File is Encrypted using below mechanism

}catch (Exception e) {
System.out.println(e);
}finally {
try {
encFileIn.close();
decFileOut.close();
} catch (IOException ioe) {
}Is there any mechanism is available for FIPS81 or Is there any third party Provider available for it plz reply........????????I suggest you look in google http://www.google.co.uk/search?q=SWF+java

well i set a passcode on my iphone 4 and ive forgotten it i have no idea what to do and i only just got this phone plus i dont want to do these bypassing with emergancy call just in case i get it wrong plz help (urgent)
If you set the phone to erase on 10 failed passcodes - then just keep typing and it will wipe itself.
Otherwise I believe you can set it to recovery mode and restore etc.. via iTunes... There is no easy way as the passcode is designed to protect the phone exactly against what you are trying to do now...

It's froze my ipad messages app. Plz help tell me what to do.
You can backup the iPad and then do a restore to factory condition which will completely wipe it: Settings > General > Reset > Erase All Content and Settings. But, before doing that remember, it completely erases everything.
You then have to restore from a backup...if you have a backup from before the bad message, you can use that and be fine. If not, you would be better off setting up the iPad as new and then redownload your apps and music...you can do that by going to the app store and itunes and tap the Purchases button and redownload everything.
You will loose your photos and email, and such in the process, however. If you have iCloud, put the photos in PhotoStream and then use that to put them back on the iPad.
Without a good backup from just before the bad message, erasing is going to cause you a lot of work. -

hi when i open my application folder, all the application is shown in trash folder. when i click the application it says this app is in trash first move it out. and when i try to open through finder> go it says this file doesn't exist. can some1 plz help? how can i put all my application through application folder?
Something really odd is going on. In your first screen shot, I noticed that the Applications folder does not have the proper icon displayed in the side bar. Also, in the title bar it lists it as Applications 08-59-29-909.
Not sure where it's picking up that odd name, unless it's because it's still truly within the Trash folder.
Try this. In the Finder > Preferences > General > turn on "Always open folders in a new window". (I have a feeling you have the default setting with this off).
Now, in Finder > Go > move down and open the Applications Folder from there. Now open the folder where you see all your applications that you show in your screen shot, select all, and move them to this true appliactions folder.
This is what you should properly seeing (but with different apps listed):
See how the Applications folder has the icon of the letter A shaped with a pencil, ruler & pen. -

You said you updated yur 1G iPod to 4.2.1. A 1G can only go to 3.1.3 and thus you must have jailbroken it to get to 4.2.1 and that can cause problems.

These are two possible approaches that will normally work to move an existing library to a new computer.
Method 1
Backup the library with this User Tip.
Deauthorize the old computer if you no longer want to access protected content on it.
Restore the backup to your new computer using the same tool used to back it up.
Keep your backup up-to-date in future.
Method 2
Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
Both methods should give the new computer a working clone of the library that was on the old one. As far as iTunes is concerned this is still the "home" library for your devices so you shouldn't have any issues with iTunes wanting to erase and reload.
I'd recommend method 1 since it establishes an ongoing backup for your library.
Note if you have iOS devices and haven't moved your contacts and calendar items across then you should create one dummy entry of each in your new profile and iTunes should merge the existing data from the device.
If your media folder has been split out from the main iTunes folder you may need to do some preparatory work to make it easier to move. See make a split library portable.
Should you be in the unfortunate position where you are no longer able to access your original library or a backup then then seeRecover your iTunes library from your iPod or iOS device for advice on how to set up your devices with a new library with the maximum preservation of data.

hi im having huge problems trying to install flash for my mac 10.5 imac, iv gone through the internet and tried all of the solutions, everytime i try to install flash it says cant read the download file, or it just wont install, anybody plz help!
iv unistalled flash, iv checked plug ins it just wont work,It would have been a great help to know precisely what Mac you have, so some of the following may not apply:
You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS. Note that version 10,1,102,64 is the last version available to PPC Mac users*. The latest version,10.3.183.23 or later, is for Intel Macs only running Tiger or Leopard, as Adobe no longer support the PPC platform. Version 11.4.402.265 or later is for Snow Leopard onwards.
(If you are running Mavericks: After years of fighting malware and exploits facilitated through Adobe's Flash Player, the company is taking advantage of Apple's new App Sandbox feature to restrict malicious code from running outside of Safari in OS X Mavericks.)
* Unhelpfully, if you want the last version for PPC (G4 or G5) Macs, you need to go here: http://kb2.adobe.com/cps/142/tn_14266.html and scroll down to 'Archived Versions/Older Archives'. Flash Player 10.1.102.64 is the one you download. More information here: http://kb2.adobe.com/cps/838/cpsid_83808.html
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/909/cpsid_90906.html
and also that you follow the instructions closely, such as closing ALL applications (including Safari) first before installing. You must also carry out a permission repair after installing anything from Adobe.
After installing, reboot your Mac and relaunch Safari, then in Safari Preferences/Security enable ‘Allow Plugins’. If you are running 10.6.8 or later:
When you have installed the latest version of Flash, relaunch Safari and test.
If you're getting a "blocked plug-in" error, then in System Preferences… ▹ Flash Player ▹ Advanced
click Check Now. Quit and relaunch your browser.
You can also try these illustrated instructions from C F McBlob to perform a full "clean install", which will resolve the "Blocked Plug-in" message when trying to update via the GUI updater from Adobe.
Use the FULL installer for 12.0.0.44: Flash Player 12 (Mac OS X)
And the instructons are here: Snow Leopard Clean Install.pdf
(If you are running a PPC Mac with Flash Player 10.1.102.64 and are having problems with watching videos on FaceBook or other sites, try the following solution which fools the site into thinking that you are running the version 11.5.502.55:)
Download this http://scriptogr.am/nordkril/post/adobe-flash-11.5-for-powerpc to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work. -
