There were no results for I've downloaded the kindle app to my new iPad4 but when I went to Amazon UK and tried to download a book it said "this mobile app does not currently support digital downloads.

Do I have to do it onto my computer and then sync it onto iPad? surely not?

I don't understand the charges on my credit card for itunes. please help
Your credit card is only linked to one iTunes account, and you've checked the purchase history on it via your computer's iTunes as per the page that you posted from ? And you don't have iTunes Match or any auto-renewing subscriptions (I'm not sure if they show on the purchase history or not, I don't have any so I can't check) : http://support.apple.com/kb/HT4098
And you haven't added or changed your credit card details on your iTunes account ? Each time that you do so a small temporary store holding charge may be applied to check that the card details are correct and valid and that it's registered to exactly the same name and address as on your iTunes account - it should disappear off your account within a few days or so. Store holding charge : http://support.apple.com/kb/HT3702
If you can't find anything on your account's purchase history then you should probably contact your card issuer and get the card cancelled and replaced. You can also contact iTunes Support via this page : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption
I don't know what your second post means. -

I got those errors like above!!! I don't understand what the
instructions said. any assistance would be appreciated!David,
I am afraid that the
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE ('An error occurred');
was my fault. I had intended it as an example to provide only
minimal syntax where no exception handling whatsoever previously
existed. Beau is a student and I am trying to guide him in the
right direction without just writing all of it for him. In
fact, I am afraid I may have already provided too much code
without sufficient explanation. For you and others who may wish
to help, here are the e-mails that provide the background on how
we got to this point, with the most recent on top, starting with
the last resonse I sent to him:
Things that are wrong:
The instructions say to be sure to use the sequence number for
the student's ID, so you should not have p_stuID as an input
parameter. Instead you should create a variable and select the
student_seq.nextval into the variable from the dual table and
use that value to populate the stuid column.
Your input parameters should only have the variable type, not
the size, so just use varchar2 and number.
The check constraints only belong in the script that is used to
create the table, not in your procedure with your input
parameters, so remove them from the procedure.
The order and number of your columns you are inserting into and
values you are inserting must match, so if you insert into fname
then lname, you need to insert the values p_fname then p_lname.
You must either have first name then last name in both or last
name then first name in both, not one way in one and the other
way in the other.
The idea is that when you execute the procedure you specify the
values of the input parameter variable, then use those input
parameter variables to insert the values into the table. You
should not be specifying any specific values anywhere in your
procedure. In other words don't insert 'HEATHER', instead
insert fname, and so on.
You should only have one insert statement. Each time the
procedure is executed, a different set of values will be
provided, and the same insert statement will be used.
Additional suggestions:
Although it is not required, since IN is the default, it is
generally considered to be a good programming practice to use IN
with your input parameters. It just makes the code easier to
read and understand. As you write other code, you will learn to
use OUT for output parameters and IN OUT for parameters that are
both input and output parameters.
It is generally recommended to store all data in upper case,
that is capital letters, so that it is easier to index and
search and avoid duplicates and so on. In order to ensure that
your data is input in upper case, it is a good idea to use the
UPPER function.
Different programmers and companies have different standards
that they use for capitalization, indentation, spacing,
alignment, and so forth to make their code uniform and easier to
read. You may want to look at some various styles and see what
you like or ask what your instructor recommends.
You should add some sort of exception handling section. For
example, if someone attempts to insert a value for standing that
isn't acceptable, then the procedure will fail due to the
constraints and the student will not be added. You probably
want to display some sort of message to the user. You might
also want to display a message if the input is successful.
When you attempt to compile your program and you receive a
message that says "Warning: Procedure created with compilation
errors." or some such thing, then from the SQL> prompt, type
SHOW ERRORS and it will list the error message number, a brief
description of the problem, and the line of code that the
problem occurred on. You can then type LIST and it will list
the code with line numbers, so that you can tell what line
number the error message is referring to.
In the following example, I have fixed the things that were
wrong, formatted it the way I usually do, and added minimal
exception handling and messages. There is a lot more that you
could do. I have also demonstrated how the program can be
tested and the results of proper input and improper input. In
the example below, two students are added correctly, then an
attempt to add another fails because the standing is not valid
and violates a check constraint, because graduate is not
acceptable. After each execution of the procedure, I have
queried the table, so that you can see what was added and what
was not.

I am not sure what part of it you don't understand.
The first section that you included is a script that you need to
copy and run, in order to create the sequences, tables, and data
that you will need to complete your assignment. You will need
to edit an empty .sql file, copy the script into the file, save
the file, then start the file. For example:
SQL> EDIT test
Type or copy the script and save the file.
SQL> START test
You should see various messages as the items are created. Then
you can use the following commands to see the tables and
sequences that you have created:
SQL> SELECT table_name FROM user_tables;
SQL> SELECT sequence_name FROM user_sequences;
To show the structure of an individual table, for example the
course table:
SQL> DESC course
To show the data in an individual table, like the course table:
SQL> SELECT * FROM course;
In the second section that you have provided, your instructor is
asking you to create three different procedures to do three
different things. To create a procedure, you edit a .sql file,
type the code to create the procedure, save the file, then start
the file. I usually make the .sql file name the same as the
procedure name. So, for example, in number 1, you are asked to
create a procedure named AddStudent, so you would:
SQL> EDIT AddStudent
Type your code.
Save the file.
SQL> START AddStudent
You should receive a message that says:
Procedure created.
Then, to execute your procedure:
SQL> EXEC AddStudent (put your parameter values here)
The basic syntax for creating a pl/sql procedure is:
CREATE OR REPLACE PROCEDURE procedure_name
(put your parameters here)
AS
put your variable declarations here;
BEGIN
put your code that you want to execute here,
like insert statements and update statements;
END procedure_name;
So, if you are trying to create a procedure to add a new student
(which means inserting a row into the student table), you will
need to accept the values (parameters) that you are going to
insert, then insert them:
CREATE OR REPLACE PROCEDURE AddStudent
(p_first .....
p_last .....
p_major .....
p_standing .....
p_GPA .....)
AS
BEGIN
INSERT INTO student .....;
END AddStudent;
I have just given you a starting format and deliberately left
out a lot, because you will learn more by doing it yourself. I
hope that makes things a little clearer.
I would like to know a little more about the class you are
taking. Please let me know where you are going to school, who
your instructor is, what is the name of the class you are
taking, and what book are you using. Also, please let me know
where you got my e-mail address (from one of the forums?)
Good luck,

The lab notes from my professor said
1. your system will often need to create a new student. Write
PL/SQL code for an object named AddStudent that will take values
for first and last name, major, standing and GPA and add a new
record in the Student table. Since advisors aren't assigned at
registration time, we'll add their advisor at a later date.
Don't worry about the student's address. Be sure to use the
sequence number for the student's ID.
2. Write a procedure that will retrieve an existing record in
Enrollment usiing the student and section Ids and set the grade
to a specified value. (use update instead of insert)
3. Write another procedure that will assign a given student a
given advisor. -
Why is this an error??? I don't understand why it is... Help Please
Hi,
Ok, I'll preface this by saying there's a lotta code pasted in here but it really quite an easy question, I just need to post all the code so you understand where what came from.
Now.............the question I'm trying to do is to create an applet that has 2 buttons -- each button when clicked opens an application (one is a simple calculator, the other a Mortgage calculation app). When you click one of the buttons (calc or mortgage), that app opens infront of the 2 button menu so its in "focus". The button on the 2 button menu then switches to a "hide app X" button (ie: "Mortgage", changes to "Hide Mortgage"). Thus if you click the hide button, the app that was opened is hidden, and then that "hide" button switches back to the original "app X" button. Pretty simple.
Now, I have from my text book an example that does exactly this, with the simple calculator already in it, and with another app (a traffic light thing) where the Mortgage should be in my final product. I also already have the Mortgage applet I need to insert from another book example in place of that Traffic Light portion.
Now, common sense would dictate that I should be able to just copy my code for the Mortgage applet into the example that has the 2 button menu structure, and overwrite the code I want to get rid of (the traffic light) with the mortgage code & rename the menu buttons. Right?? A simple switch of one thing for another... but therein lies my problem.
I copied all the Mortgage code in correctly over the traffic lights, switched the button names, tried to compile it but I get one error....
Exercise12_17.java:52: cannot resolve symbol
symbol : method pack ()
location: class MortgageApplet
mortgageAppletFrame.pack();I don't understand why..... mortgageAppletFrame.pack(); was a simple rewrite from lightsFrame.pack(); like every other line...... it should work. I've gone over it for 2 days......... Anyone know why it comes up as an error???
Below, in order going down is (1)my code with the 1 error I can't solve, (2)the original menu example I tried to edit, and (3)the Mortgage app code...........
Does anyone know what my error is?? Help or a hint would be greatly appreciated........ Thanks.
My erroring app.......

I have been on something called Disk Utility and Activity Monitor but don't really understand what I'm looking for. It seems a large percentage of my mac is 'idle' if that makes sense. Someone said to look at Page Out but I really don't understand what that means and what sort of numbers are normal.
I do have some storage left so I don't think it could be that. A lot of my gigabytes seem to be taken up by movies and 'other'. I've tried deleted a load of videos but it hardly made a difference. I have Mac Mail and it seems very slow on my Macbook compared to on my Ipad and iphone. iCal is also very slow on here and it always takes a while to load internet pages. It isnt the wifi connection.
Please help and bear in mind I am by no means a Mac whizz so you might have to talk in layman's terms!
Thanks,
AmyIf you have more than ten or so files or folders on your Desktop, move them, temporarily at least, somewhere else in your home folder.
If iCloud is enabled, disable it.
Disconnect all wired peripherals. Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Step 2
Launch the Console application in the same way as above, and select “kernel.log” from the file list. Post the dozen or so most recent messages in the log — the text, please, not a screenshot.
If there are runs of repeated messages, post only one example of each. Do not post many repetitions of the same message. -
Don't understand the cc cleaner tool
Good morning and happy new year.
I must be the dumbest people here but I tried to follow the cc cleaner tool process explained here and I'm at a loss and stopped before making a fool of myself.
I went through the process 1 and 2 ie. I have a disk repair and an external disk backup of my system driver. (I use Win 7 Ultimate fully updated). My projects are NOT on the system drive as well as all the clips I use .
question : Will CC cleaner delete on the system drive any information related to my projects? I need a precise answer: No or Yes. The "perhaps", "maybe" etc evavive answers are not acceptable in such situations.
In the step 2 of the help file I uninstalled with Win 7 uninstall manager different elements from CC and CS 6 that either I have no use of or that I wont use anymore as I want to stick to the latest version of CC which are PPro, AE and Mediaencoder for the moment.
We arrive to step 3 and there I just don't understand why I should have to uninstall programs I uninstalled in the previous step. Will that step totally erase the whole programs of CC for example, or will it just clean remaining items or directories specifically related to for instance Prelude CC 2014 ? Can't people who write these messages in their scripts be once and for all precise in their wording saying what will be done?!
In this present instance I need to make a clean re-install of Mediaencoder CC as there has been most probably a problem during the recent update although it was completed without any error messages; I can't anymore re encode a project although I have not changed a line of it! The program stops suddenly and reboots my computer. I have not changed anything in the computer as well and the hardware is not the cause of the problem as it is only Media encoder which provokes the crash when it did not before the update.
This will be probably considered an ill mannered way of presenting my problem by I'm sorry to say that one cannot work cautiously enough and I don't want to see weeks of work erased and not usable even with backups because a user manual is not clear and precise in its wording. This infuriates me and I wish to know where I set foot!
Again sorry for my bad temper but really this is stressing.
Thanks in advance for your help

My project is on driver G, my clips are on D, E and G, with a majority of them on G; Cloud CC 2014 is on Driver C with Windows 7
B/What version of Premiere Pro are you running currently? Do you have any third party plug-ins or hardware you using in conjunction with Premiere Pro? Do you know what version of Media Encoder you were using successfully before the recent update and you started having problems?
I use exclusively since I took the subscription to Cloud CC, the latest versions, I check updates or upgrades every week and of course get notification also by the automatic Cloud manager of any new version. My last update was done on the 30th of December 2014. So yes I run with the most recent programs; the problems occurred just after! And got aggravated yesterday for no reason when Media encoder and Premiere Pro did not recognized MP4 format clips with an error message that the format was not supported!!! I hope Adobe did not decide to abandon this format, because it would put my 2 projects in full jeopardy!
Before the last update I had no problems. I have uploaded on Vimeo a provisional encoded file (see
with password rja404177 .
I decided to separate my project in two master projects concerning each of them the 2 parts of the video, with different names as to make the projects less heavy to manage by the computer and also easier to correct or change some of the effects controls especially the use of the curves RGB effect. I have a problem of getting an even colorimetric view between three different sources of files and cameras, one source is analog, the others HD and one of the latest has been more or less over exposed, so I check every clips with the YCscope and RGB parade and Vectorscope ( there could be a problem of color broadcast due to the red of the cliffs). Just imagine what would happen If I had to do it again! The full video is 1h10 minutes long! The video here corresponds to the first master project before the division in two parts. As I use nested sequences I have transferred in the master sequence here the 3 first sequences of the film (Titles, Las Vegas to Lee's Ferry, 1st day on the river).
Yes I have Video Copilot addons but which are not used in the project as well as Red Giant Universe Premium also not used here. In fact I seldom use special effects in these projects as they are kind of documentary on my raft trip down the Colorado in 1995 updated with films of two friends done 2011 and 2013. The only effects used are Cross dissolve and the Slide push one twice in the project for the last one. I use otherwise the default controls of scale and opacity if necessary. Soundwise, my tracks are declared 5.1 and used in conjunction with Audition CC (I've been a user of this last program for many years since it's creation by Syntrillium under the name CoolEdit Pro before Adobe acquired it!)
May I add that I'm not a novice with computers although an old froggy of 73!LOL! I began using computers in 1972 besides my job of Financial Analyst. I developed software in APL+ for stocks buy and sell decision making and created in France the first financial database in 1978 I was considered at that time like a perfect crazy guy in my business, good to be put in an asylum!!!. Since then I must say I had a good laugh! Try to prevent a trader to use a computer and databases nowadays and you'll see the speed at which he will throw you out of the window!
C/I would probably have focused on just Media Encoder if possible but whats done is done. Maybe you did?
Yes you're right I sort of thought of Media encoder first, but revised my way of dealing with the problem thinking that may be the installation had not been done correctly although no problem occurred during the update. I always update one program at a time waiting it to be fully completed before clicking on the install button of the next one.
D/ about the two methods of uninstall.
You say "The cleaner tool removes the same directories as the standard uninstaller. However the uninstaller is definitely the preferred method as it is done in conjunction with OS and the registry versus scripts which don't. The cleaner tool is generally used when the standard uninstall method fails "
May I say I'm not sure this is the right way to do from the user viewpoint. It is misleading. I'm again neither a professional in development although I mentioned what I did when I was not retired, and not a professional in Video editing etc.. I just address the problem from the user's point of view. If Adobe thinks that the Management panel solution is the best solution to have all the files eliminated let's stick to it. In fact one can see by using the CCleaner program that it does not eliminate all the register's problems after having uninstalled a program. So perhaps then it is justified to use also the Adobe CC Cleaner device. Then may I suggest that the phrasing of the step 3 be changed to make the user understand its real purpose. From what you say one induces that they are complementary. This should be perfectly clear in the user's brain. When I tried to find answers to my problems on the forums it showed many times that people did not really understand what would happen, how the device was going to work. That's why I insisted in my question on the "precise, yes or no " etc.. answers required. I can dedicate time to such questioning, I doubt a professional having to deliver a final product under contract has time to make hypothesis on this matter if it occurs to him such mishaps....
E/ miscellaneous questions:
Yes I use the default format proposed by Media encoder H.264 preset : Match source high bitrate which matches my project's settings. It worked three times before the update without an hitch. Why should not it go on like that?
The encoded files are saved either on the driver of the project file, or on the E external driver to make sure I do not erase the final encoded file by mistake. Poirot's little grey cells are a little bit rusty nowadays!
I had no problems before the update by working like that.
I did not try a different codec before the last event which is the impossibility of using my MP4 clips. By the way the projects contain also AVI uncompressed (codec UYVY) files (My quicktime version is also updated) and the native files of my Canon Legria AVCHD camera (AVC format) and I used the AVI uncompressed format because I wanted to derush my analog files to eliminate any shots which were of poor quality. I use for this a small software: AVI Cutty which works only with AVI uncompressed files. So I used Media Encoder to pre encode my analog files in this format first; It separate automatically my videos in clips more or less corresponding to scenes. Again I had no problem since I began to use Adobe software more than a year ago with CS5.5 and then with CC 2014 since last September as a yearly subscriber.
Both projects have the same problem.
I checked the Windows task manager while encoding and I observed this:
a/ the crash occurs randomly in time.
b/ it seems that each time the encoding passes on a cross dissolve section (I'm not certain of that it can be also the changes in the curves RGB effects settings from one clip to the other.) the CPU usage curve reaches a peak around 95 to nearly 100%. I suppose the crash occurs when the 100%+ is reached.
c/I've checked my system driver's integrity, there is no problem here. I did the same for the memory which is ok too.
d/ No I did put the question on other forums because I did not find the right place to put it.
I do my best not to pollute other forums with non related questions.
e/ As for the recognition of the MP4 files, other programs like the Windows mediaplayer recognize them so it's not a question of corrupted files.
f/ I've just checked with the reinstalled media encoder. I did not re-encode but I do not get any more messages that the MP4 format is not recognized! Thank god! Remains to test the re-encoding itself and PP when the installation is over.
Well I hope this long answer gives you a better idea of what is going on. I'm finishing right now the re installation of PP AE Media encoder and Audition and will come back to you with the results.
Thanks again
Best

Create SP that returns value and at the same time displays query result in output window
I would like create an SP which will return the records from the table and also return value to my c# client application.
For Example:
Select * from employee returns all the query results in output window.
Now I want to create an SP
Create procedure Test
As
Declare @ret int,
Select * from employee
set @ret = Select count(*) from employee
if @ret > 0
return 1
else
return 0
The above algo should return 1 0r 0 to c# client application and at the same time display all employees in sql query output window.
Can u pls help in this regard.The above algo should return 1 0r 0 to c# client application and at the same time display all employees in sql query output window.
Why? and No!
Why? Your procedure generates a resultset of some number of rows. You check the resultset for the presence of rows to determine if "anything is there". You don't need a separate value to tell you this. Note that it helps
to post tsql that is syntactically correct. While we're at it, if you just need to know that rows exist there is no need to count them since that does more work than required. Simply test for existence using the appropriately-named function
"exists". E.g., if exists (select * from dbo.employee).
No! A stored procedure does not display anything anywhere. The application which executes the procedures is responsible for the consumption of the resultset; it chooses what to do and what to display.
Lastly, do not get into the lazy habit of using the asterisk in your tsql code. That is not best practice. Along with that, you should also get into the following best practice habits:
schema-qualify your objects (i.e., dbo.employee)
terminate every statement - it will eventually be required. -
I don't understand why appear new decimals.
Hi Jorge,
Instead of using
Data.SetValue(FormatDouble.DecodeDouble(self.PKg));
use
Data.SetValue(FormatDouble.DecodeDecimal(self.PKg,Data.Scale)); //
This will take the second parameter of scale
You will see the desired results.
Thks,
Sanjay

Simply put, the problem stems from the fact that
floating-point arithmetic is inherently imprecise.
Rounding errors are common.
With doubles, you get 16 digits of accuracy. Beyond
that there is no guarantee.

Don't understand IMAQ image behavior
Hi there,
I have several image controls in my application. When I assign image A to image B (in my wiring diagram), and then close image B, image A is no longer valid! When I try to crop image A after closing image B, I get a "not an image" error. If I do not assign image A to image B, I don't get the error. If I do not close image B after assigning image A, I don't get the error.
I am new to IMAQ and don't understand this behavior at all. It looks like when I try to give the value of image A to image B, it somehow links the two rather than just copying the information over. Is this a pointer and reference vs. value assignment issue?
Regardless, these IMAQ image controls behave differently than any other control in the labview palette. I hope someone can explain what I am seeing to me so that I that I can learn when I can assign one image to another, and when I can close, and how I can avoid extremely confusing and difficult to debug results.
Thanks,
EricHi,
You must create each of Image A and Image B separately using IMAQ Create and then copy content of image A to image B using IMAQ Copy.
Image Display control in Labview does not create an image and does not reserve memory for it. It just displays content of the image it is wired to. I suspect that when you "assign" image A to image B in your program, you just wire the same image to 2 Image Display controls. No wonder they show identical image. When you "close image B", you actually closing the only image you have, memory space allocated fot that image is released and reference is no longer valid. After that any attempt to modify/change that image will return "not an image" error.
I recommend you to look into Vision examples shipped with Labview - see for example "Extract Example.vi" in "C:\Program Files\National Instruments\LabVIEW 7.1\examples\Vision\2. Functions\Image Management". In the path above you should change LabVIEW 7.1 to your version of LabVIEW. -

Don't understand why WSDL isn't valid
In Workshop 9.2, I'm developing an annotation-based web service. I imported my schemas and generated the xmlbeans, and after setting my input and output parameters in the service class, I tried to generate the WSDL from the service. For some reason, the WSDL is not valid, and I don't understand why. I'm sure it's a namespace issue, but I don't see it.
The enclosed WSDL is somewhat paraphrased from the generated WSDL.
On line 76 (marked with a comment), there is the first of several errors. It says:
"The input element is referencing an undefined message 'overrideRequest'. Check that the message name and namespace are correct and that the message has been defined."
Here is the WSDL:

--------------------After I made these changes and re-validated, I get a dialog that says "The WSDL file is valid however warnings have been issued. See the Problems view for a list of the validation warnings", and I see the following in the Problems list:

In in my WSDL editor, the lines in question still have a red circle with a white "x" in the left margin, and the tooltip still reports the same errors as before.
In the "Error Log" view, I see the following:

CREATIVE CENTRALE, PLEASE, I REALLY DON'T UNDERSTAND
HELP!!!! I really don't understand. I always buy creative, they sound awesome, I hate ipod, I have several players, I tell people about the hardware, but, WHY, WHY, WHY? such unimaginably amazingly good hardware and abso-lutely appalling and useless softwafre?? It really spoils the whole experience.
TAKE NOTE CREATIVE. PLEASE, PLEASE, PLEASE CAN YOU DO SOMETHING ABOUT YOUR ATROCIOUS, RUBBISH, UNSTABLE AND UNFATHOMABLY HARD TO USE AND UNINTUITIVE SOFTWARE AS IT IS TOTALLY RUINING MY OTHERWISE EXCELLENT CREATIVE EXPERIENCE!!!!!
Creative Centrale is appallingly bad, creating a new playlist is like torture, now it wont work at all and I have reinstalled it many times. I am going to (reluctantly) have to buy a new player to replace my lovely little Zen Mosaic JUST so I can get some decent software to create playlists.
Really this is beyond belief guys, best hardware out there, worst software. Want to know how Apple became no ? No, it wasnt the flashy looks, all that kudos came later, how they really became no is simple, despite continuing?
concerns over their hardware it was their fantastic, easy to use intuiti've software for ALL their products that did it.
Hell-ooooo!!! Wake up. Such a shame. Rant over.
If anyone knows of another program I can download to help me use my little Mosaic (its my friend, I listen to it every day, for hours) then please let me know. TI have this piece of code:
private static String[] getArgs(String command){
System.out.println(System.currentTimeMillis()-startlog+
: "+"In getArgs.");
command = command.substring(3, command.length());
System.out.println(System.currentTimeMillis()-startlog+
: "+"The command: "+command);
String[] args = new String[0];
int last = 0;
System.out.println(System.currentTimeMillis()-startlog+
: "+"Command length: "+command.length());
boolean exit = false;
int end = command.length();
int count = 0;
while(count<=end){//Why don't this cicle ends!?
System.out.println(System.currentTimeMillis()-startlog+
: "+"(count="+count+").");
if(command.charAt(count)==',' ||
command.charAt(count)==';'){
System.out.println(System.currentTimeMillis()-startlog+
: "+"Found ',' or ';'.");
args = addColum(args);
args[args.length-1] = command.substring(last, count);
System.out.println(System.currentTimeMillis()-startlog+
: "+"Found arg: "+args[args.length-1]);
last = count+1;
count++;
System.out.println(System.currentTimeMillis()-startlog+
: "+"Returning args.");
return args;
}And the output is this:
14148: In getArgs.
14148: The command: TextIO.java;
14149: Command length: 12
14149: (count=0).
14149: (count=1).
14149: (count=2).
14149: (count=3).
14161: (count=4).
14161: (count=5).
14161: (count=6).
14161: (count=7).
14162: (count=8).
14162: (count=9).
14162: (count=10).
14162: (count=11).
14162: Found ',' or ';'.
14162: In addColum.
14162: Found arg: TextIO.java
14166: (count=12).
Why don't the cicle ends?whats printed out after
14162: Found arg: TextIO.java
14166: (count=12).
