Question about ++ operator

int i = 0;
i = i ++;
System.out.println(i);
the result is 0.
i know the executing sequence is: first =, then ++.
but, ++ operator DOES execute. so, if it doesn't affect the i's value, then it affects what?
anyway, i couldn't understand why the output is 0!

i know the executing sequence is: first =, then ++.Check that precedence table again. ++ is a full 13 or 14 levels higher than =.
This means that i = i++; is equivalent to i = (i++);Because i++ == 0, the above statement has the same effect as i = 0;

Question about operating system

Hello.
I just got lenovo T400. I have question about operating system. I choose OS (Windows XP Professional preinstalled through downgrade rights in Genuine Windows 7 Professional). When I get the laptop, Windows XP is preinstalled but I don’t know how to upgrade to Window 7. Please, tell me the way to upgrade.
Have a nice day

you'd need the disks, and would need to do a fresh install, i.e. you can't just upgrade it. everything will be gone

Don't pm me for help! That's what the forum is for. Also, Google's nicer than me. Ask him.

Question about operating system reinstall on Portege R500

I have purchased the R500 64SSD version, and for some reason it never struck me to check if there was a DVD drive on it.
That was rather embarassing.
I know it is easy to purchase an external drve to copy software etc on to the Portege, so that isnt so bad.
However, I am considering a re-install, possibly to XP, but maybe just to reduce the repulsive amount of bloatware i got on my machine when i switched it on.
Now to the crux of the matter: if i use an external USB disk drive, i need USB drivers. If i delete the OS, that will delete the drivers.
So, finally, my question is: How in the name of Hell is anyone supposed to put a fresh install into an R500?
Thanks for your patience.

I understand everything till the point with the bloatware.
But what I dont understand is: what do you want with a USB disk drive? I hope you dont mean a USB-HDD (its a little bit confusing). ;)
Usually you can use all drives without the need of some drivers because the machine offers you the option to boot from a USB device after powering the machine up and see the Toshiba logo pass...
You must only press F12 and choose the option to boot from an external USB CD/DVD drive. Thats all.

Question about operations allowed in methods of stateless and stateful bean

Hello,
Can anyone tell me why ejbRemove and ejbCreate are allowed entreprise beans and resource manager access in stateful session beans and not in stateless session beans?
Thanks in advance,
Julien Martin.

Salut Julien,
Can anyone tell me why ejbRemove and ejbCreate are
allowed entreprise beans and resource manager access
in stateful session beans and not in stateless session
beans?I'm not sure I fully understand your question, but here is some information that may answer it.
The user is the one who creates and removes a stateful session bean. The container is the one who creates and removes a stateless session bean. So the user can pass any parameters to the create of a SFSB because he theorically knows what to pass. The container doesn't, and doesn't want to. It just wants to create SLSB to pool them, but it doesn't pool SFSB.
Maybe it doesn't answer your question. Can you reformulate?

Question about "operations" button

Hello all,
Before my main menu is displayed in the Flow chart I want an 8 second clip to be the first thing that plays and for the viewers not to be able to skip it. So from my blue disc in the flow panel I link to this clip in my timeline. When I select "none' for operations it still allows me to use the "next" button to get to the main menu and skip my 8 second clip.
What am I doing wrong?
Thanks,

Thanks again for your help
I do have DVD RW's so I will be putting them to good use.
I just burned my project and everything went well except.....
All my chapter links play fine but I don't have any control options, i.e. fast forward, back to the main menu etc. When I went back to the project I did see that the "user operations" was set to none for all my links to the various chapters in my timeline. When I tried to open up the dialog box where I could change it to "all" it simply would just not open, no error message as well.
What am I doing wrong?
Thanks

Hi All, I have question about the iMac operating system. I have the last updated. The problem when I manage the place of the folder windows they are all mixing up. I mean they not on the place where I left them. how to set they stay on the same place? I know there are different possibilities to set.
I tried but it not helped for me. What I can do? How and where can set this they stay on their place?
Thanks.

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Some questions about Muse

First of all, I would like to say that I am very impressed with how well Muse works and how easy it was to create a website that satisfies me. Before I started a daily updated website I thought I would encounter many problems I will not be able to solve. I have only had a few minor issues which I would like to share with you.
The most problems I have with a horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html). Marking and copying of a text is possible only on the last (top) layer of a document. The same situation is with widgets or anything connected with rollover state - it does not work. In the above example it would be perfect to use a composition/tooltip widget on the first page. Unfortunately, you cannot even move the cursor into it.
It would be helpful to have an option of rolling a mouse to an anchor (like in here http://www.play.pl/super-smartfony/lg-nexus-5.html and here http://www.thepetedesign.com/demos/onepage_scroll_demo.html). I mean any action of a mouse wheel would make a move to another anchor/screen. It would make navigation of my site very easy.
Is it possible to create a widget with a function next anchor/previous anchor? Currently, in the menu every button must be connected to a different anchor for the menu to be functional.
A question about Adobe Muse. Is it possible to create panels in different columns? It would make it easier to go through all the sophisticated program functions.
The hits from Facebook have sometimes very long links, eg.
(http://www.leftlane.pl/sty14/mclaren-p1-nowy-krol-nurburgring.html?fb_action_ids=143235557 3667782&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582). If such a link is activated, the anchors in the menu do not work on any page. I mean the backlight of an active state, which helps the user to find out where on page they currently are. The problem also occurs when in the name of a html file polish fonts exist. And sometimes the dots does not work without any reason, mostly in the main page, sometimes in the cooperation page either (http://www.leftlane.pl/wspolpraca/). In the first case (on main page), I do not know why. I have checked if they did not drop into a state button by accident, moved them among the layers, numbered them from scratch and it did not help. In the cooperation page, the first anchor does not work if it is in Y axle set at 0. If I move it right direction- everything is ok.
The text frame with background fill does not change text color in overlay state (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html). I mean a source button at the beginning of every text. I would like a dark text and a light layer in a rollover, but the text after export and moving cursor into it does not change color for some reason.
I was not sure whether to keep everything (whole website) in one Muse file (but I may be mistaken?). I have decided to divide it into months. Everyone is in a different Muse file. If something goes wrong, I will not have any trouble with an upload of a whole site, which is going to get bigger and bigger.
The problem is that every file has two master pages. Everything works well up to the moment when I realize how many times I have to make changes in upper menu when I need to add something there. I have already 5 files, every with 2 masters. Is there any way to solve this problem? Maybe something to do with Business Catalyst, where I could connect a menu to every subpage independently, deleting it from Muse file? Doing so I would be able to edit it everywhere from one place. It would make my work much easier, but I have no idea jendak how to do it.
The comments Disqus do not load, especially at horizontal layouts (http://www.leftlane.pl/sty14/2014-infiniti-q50-eau-rouge-concept.html). I have exchanged some mails and screenshots with Disqus help. I have sent them a screenshot where the comments are not loaded, because they almost never load. They have replied that it works at their place even with attached screenshot. I have a hard time to discuss it, because it does not work with me and with my friends either. Maybe you could fix it? I would not like to end up with awful facebook comments ;). The problem is with Firefox on PC and Mac. Chrome, Safari and Opera work ok.
YouTube movie level layouts do not work well with IE11 and Safari 7 (http://www.leftlane.pl/sty14/wypadki-drogowe--004.html). The background should roll left, but in the above mentioned browsers it jumps up. Moreover the scrolling with menu dots is not fluent on Firefox, but I guess it is due to Firefox issues? The same layout but in vertical version rolls fluently in Firefox (http://www.leftlane.pl/sty14/polskie-wypadki--005.html).
Now, viewing the website on new smartphones and tablets. I know it is not a mobile/tablet layout, but I tried to make it possible to be used on mobile hardware with HD (1280) display. I mean most of all horizontal layouts (http://www.leftlane.pl/sty14/2015-hyundai-genesis.html), where If we want to roll left, we need to roll down. Is there a way to make it possible to move the finger the direction in which the layout goes?
On Android phones (Nexus 4, Android 4.4.2, Chrome 32) the fade away background effect does not work, although I have spent a lot of time over it (http://www.leftlane.pl/lut14/koniec-produkcji-elektrycznego-renault-fluence-ze!.html). It is ok on PC, but on the phone it does not look good. A whole picture moves from a lower layer instead of an edge which spoils everything.
This layout does not look good on Android (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html#a07). The background does not fill the whole width of a page. There are also problems with a photo gallery, where full screen pictures should fill more of a screen.
Is it possible to make an option of scroll effects/motions for a fullscreen slideshow widget thumbnails (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06)? It would help me with designing layouts. Currently, it can go from a bottom of a page at x1 speed or emerge (like in this layout) by changing opacity. Something more will be needed, I suppose.
Sometimes the pictures from gallery (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06 download very slowly. The website is hosted at Business Catalyst. I cannot state when exactly it happens, most of the time it works ok.
I really like layouts like this (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a03). On the top is a description and a main text, and the picture is a filled object with a hold set at the bottom edge. That is why there is a nice effect of a filling a whole screen- nevertheless the resolution that is set. It works perfect on PC, but on Android the picture goes beyond the screen. You can do something about it?
In horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html) holding of a filling object does not work. Everything is always held to upper edge of a screen regardless the settings. Possibility of holding the picture to the bottom edge or center would make my work much easier.
According to UE regulations we have to inform about the cookies. I do not know how to do it in Muse. I mean, when the message shows up one time and is accepted, there would be no need to show it again and again during another visit on the website. Is there any way to do it? Is there any widget for it maybe?
The YouTube widget sometimes changes size just like that. It is so when the miniature of the movie does not load, and the widget is set to stroke (in our case 4 pixels, rounded to 1 pixel). As I remember ( in case of a load error) it extends for 8 pixels wide.
Last but not least - we use the cheapest hosting plan in Business Catalyst. The monthly bandwidth is enough, although we have a lot of pictures and we worried about it at first. Yet we are running out of the disk storage very quickly. We have used more than a half of a 1 GB after a month. We do not want to change BC for a different one, because we like the way it is connected with Muse. But we do not want to buy the most expensive package - but only this one has more disk space. We do not need any other of these functions and it would devastate our budget. Do we have any other option?
I’m using Adobe Muse 7.2 on OS X 10.9.1.
and I'm sending Muse file to <[email protected]>

Unfortunatley, there is no way to get a code view in Muse. I know quite a few people requested it in the previous forum, but not really sure where that ended up. Also, you may not want to bring the html into DW unless you only have 1 or 2 small changes 2 make. Two reasons. First, it isnt backwards compatible, so if you are planning on updating that site in Muse, you will need to make those changes in DW everytime you update. Second, by all accounts the HTML that Muse puts out is not pretty or easy to work with. Unlike you, I am code averse, but there was a lenghty discussion on the previous forum on this topic. I know they were striving to make it better with every release, just not sure where it is at this point.
Dont think I am reading that second question right, but there was a ton of info on that old site. You may want to take a look there, people posted a ton of great unique solutions, so it worth a look.

A lot of questions about my MacBook Air

I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
Product: MacBook Air
Operating System: Mac OS X Version 10.7.4
1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.
I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then. Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?
5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
In advance, I wish to thank you in this Apple Support Communites for your help. Have a safe and happy holiday weekend!

1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
7) if your printer works and it has Mountain Lion drivers, why replace it?
8) Online banking is done with a browser - Use Safari or FireFox
9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
10) you can only buy Mt Lion via the App Store.

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Striving is without limit!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!

Two Questions about Airport Express

All, I am a recent convert to using a Mac so bear with me.
I have two questions about the Airport Express.
Question if I buy one in the USA, I will visiting this week on holiday,can I use it the UK with a UK adaptor/apple plug?
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
Any help and advice gratefully received.

Hello andixbox. Welcome to the Apple Discussions!
Question if I buy one in the USA, I will visiting this week on holiday,can I use it the UK with a UK adaptor/apple plug?
Yes, but at least two things to consider:
o The US version of the 802.11n AirPort Express Base Station (AXn) only supports radio channels 1-11 in the 802.11g radio mode. Channels 12-14, used in other countries outside the US will not be available.
o The AXn supports both the 2.4 and 5 GHz radio bands for 802.11n. The 5 GHz band is restricted in certain countries (like the UK) so operating in this mode may get you unwanted attention.
That should be okay then because the Netgear broadcasts on channels 1-11. I hadn't appreciated the 5 Ghz band, but having checked both US and UK Apple sites the techspecs both mention 2.4 Ghz and 5 Ghz.
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
If your intent is to have the AXn join the Netgear as a wireless client, then yes it should work. The "$" requirement was for WEP. This shouldn't be necessary for WPA or WPA2.
I intended to use the AXn as an range extender, but you mention wireless client, is that something different?

Few questions about recovery on P100-400

Good evening all,
I have a few questions about recovering my laptop...
So, I was thinking if the only way to clean my entire disk is to use the Recovery DVD?
I ask this because I think that the computer becomes too "heavy" with all the applications it came with. So I was wondering if I can format the Hard Drive instead of recover it.
If I format the drive do I loose warranty? Is there any future problem related to genuine software?
It's possible to install Windows XP Pro (and not the actual windows xp media center) with the original Operative system's product key?
Thank you.
Best Regards.

Hello
I will try to give you few answers and I hope it will help you.

I do not understand what you mean with I can format the Hard Drive instead of recover it but you can do follow: install OS using delivered recovery media and after doing this remove all applications you do not need. After doing this maybe your notebook will not be heavy anymore.
> If I format the drive do I loose warranty?
NO.
> Is there any future problem related to genuine software?
I do not know what you mean exactly
> It's possible to install Windows XP Pro (and not the actual windows xp media center) with the original Operative system's product key?
No. Something like this is not possible. Product key belongs to delivered and preinstalled OS.

Question about the ability of Genius Bar to help with outside software...

Hi I wasn't sure where to put this, but here's my question. I'm having a problem with the Sims 2 on my Macbook and I was wondering if I go to the Genius Bar will they be able to help me or are they strictly hands off when it's not a direct Apple product?
Also, I bought an external hard drive in the Apple Store but it's not an Apple branded product. If I'm having a problem with that, can I go to the Apple Store?

If it's a question about the installation, system requirements or compatibility with your MacBook, the Mac Genius can probably help. If you're having some kind of issue while using the Sims 2, you'll probably have to contact .
The same is true with the hard drive. If you need some help getting it connected or even formatted, they can probably help. However, if it's not powering up or you're losing files or some kind of operational issue with the hard drive after it's connected, they'll probably refer you to the manufacturer.
Usually Apple can't support other vendors' products. Someone here may be able to give you some more advice, since none of us work for Apple. There may be someone here who's already had the same issue with the Sims.

Problem when using About Operator in Contains Query

Hi,
I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.
I create a table with some records and then create a context index on 'name' column.
CREATE TABLE my_items (
id           NUMBER(10)      NOT NULL,
name         VARCHAR2(200)   NOT NULL,

EXEC ctx_ddl.create_preference('english_lexer','basic_lexer');
EXEC ctx_ddl.set_attribute('english_lexer','index_themes','yes');
EXEC ctx_ddl.set_attribute('english_lexer','theme_language','english');
CREATE INDEX my_items_name_idx ON my_items(name) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer english_lexer');
EXEC ctx_ddl.sync_index('my_items_name_idx');Then I perform contains query to retrieve record :
SELECT count(*) FROM my_items WHERE contains(name, 'Japan', 1) > 0;
COUNT(*)
      1
SELECT count(*) FROM my_items WHERE contains(name, 'about(Japan)', 1) > 0;
COUNT(*)
      1But the problem is when I using ABOUT operator like in Oracle's English Knowledge Base Category Hierarchy it return 0
SELECT count(*) FROM my_items WHERE contains(name, 'about(Asia)', 1) > 0;
COUNT(*)
      0
SELECT count(*) FROM my_items WHERE contains(name, 'about(transportation)', 1) > 0;
COUNT(*)
      0I can't figure out what 's wrong in my query or in my index.
Any help will be appreciated.
Thanks,

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:
Text
And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!

I want to question about the official service at the service center of Sony.

I want to question about the official service at the service center of Sony.
long since I like the models and items sony. from start playstation, cameras, camcorders up, I've ever had. and a new camera that I bought two years ie compact cameras Sony Cybershot DSC H200. as of a month ago, a camera was having problems in lenses that would not close. and setting the automatic mode to move by itself. I came to the Sony Service Center in Makassar, precisely on Jl. Shop Pengayomann A5 / 05 (0411) 442340.
operator initially said only two weeks to work on my camera. but this week has been more dau even want to go in a month tomorrow, dated July 9, no news from the service center. and I kept the call to the office service. as well as assorted reasons. there are no spare parts or technical constraints, and the last one I call to his office, he said the factory spare part is damaged. imported directly from Singapore. I think, ko new spare part it can be damaged before using that? how the quality of this Sony spare part? ugly? not good? why?
I was disappointed with this situation, where soon it will Eid, want to return home as well to Java. but the camera has not been settled workmanship?
nah, roughly what is the solution of the Sony plagued with this problem? please help, because he did not know to whom to complain. operator had just said: it's up to the father alone.
once again I asked for his help. solution. if you can before Eid arrived.
Thank you,
AD. Rusmianto
