Getting the GUI to access and use changed variables

Hi,
I'm trying to implement a GUI which when you click the new button, a new Jframe appears on screen. The user then selects an item from a list and clicks ok. The item they select is then used as an argument to call a method from the system class. The problem is when I run the program, the GUI gets the values of the variables from the system class, before the new button and the item are selected. How can I make the Gui get the new values.?? Any help would be great as its doing my head in,
cheers

The problem is when I run the program, the GUI gets the values of the
variables from the system class, before the new button and the item are selected. No idea what you are talking about.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

In Snow Leopard you update Java from Software Update (in the Apple menu). You can check your version by opening Terminal and typing
java -version
(don't get creative and type anything else)
The latest version is 1.6.0_65.

you shouldn't have a problem, itunes allows up to a certain number of devices on the same account, around 10 maybe? we have 2 iphones, an ipod touch 4g and an ipod nano syncing and downloading from the same itunes account.

When I OCR two versions of the same document and then compare th documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago

When I OCR two versions of the same document and then compare the documents in Acrobat Pro XI, I usually get the message that there are no changes to mark. However, I know there a quite a few number of changes. I raised this question more than a year ago, and the response I received had to do with the quality of the OCR and the scans of the documents. However, if I use Acrobat Pro XI to save the same documents in Word and then run a comparison in Word all of the changes are marked. When a PDF is saved as a Word document in Acrobat Pro XI, is a different OCR module being used than the one used in Acrobat Pro XI for text recognition?

OCR is only for recoginition of the image / picture of text provided by an scanner.
Content typed into a Word file which is converted to a PDF is (in Word and in PDF) *not* an image or picture of text - it is the digital text. So, no OCR involved.
When the "digital" (renderable) text of a PDF's page content is exported to Word no OCR is involved.
When a PDF's content is from the image output of a scanner and this is a picture of text then OCR comes into play.
If this content is exported to Word before doing OCR then it is the image that is exported to the Word file.
Once OCR is performed it is the OCR output that is exported.
OCR output is (always will be) impacted by "the quality of the OCR and the scans of the documents".
Regardless "Compare" is based on a Word file output to PDF1 then edits to the Word file followed by an output to PDF2. You use Acrobat Pro to do a compare of PDF1 & PDF2.
Paper 1 scanned to image 1 to image 1 in PDF1 that gets OCR 1 and
Paper 2 scanned to image 2 to image 2 in PDF2 that gets OCR 2
being processed with Acrobat Pro's Compare can certainly be done.
But - well you've described what can be observed.
Be well...

I need to know how to access and use the Blue Tooth device that comes with the Thinkpad W520

Forgive me for being a techo illiterate. But I know that this thing supports Blue Tooth. And one "problem" with it is although it has a DVD and sound card, music and movies have very lousy audibility. Is there something I can do about that? I can barely hear anything on a movie unless I plug in head phones to the computer. But that leaves me stuck in my seat. I'd like to get cordless headsets. And I'm ready to purchase the Plantronics BackBeat 903+ Wireless Stereo Headphones - Mic, Rich Audio, Bass-boost, Voice Alerts, OpenMic, 3-way Earpiece. And have heard that it's compatable with a pc that has Bluetooth capabilities. but could someone get back to me with exactly how I access and use the Blue Tooth device?

I was searching for how to setup the 903+ and my W520 and came to this thread.
1. The OP was asking about audio and there are updated audio drivers / tweaks to get it louder / install different drivers.
but if you are going to go BT headset....
2. What I did for the 903+
Uninstalled the currently installed ThinkPad Bluetooth program. ( I forget the exact name, came stock and was out of date).
Required reboot.
Activated the Bluetooth with FN + F5 menu.
Downloaded the updated Bluetooth driver from lenovo (search lenovo driver matrix).
Ran the updated Bluetooth driver install.
Rebooted for good measure.
Double-clicked the Bluetooth Tray icon.
Clicked Add A Device.
Turned off my 903+ and continued to hold down the power to enable pairing mode.
Showed up in devices and added it.
Worked for audio. There are probably additional options for enabling the mic.
Hope that helps whoever might find this thread.

I just started getting the error message below - when I drag a file to TRASH, I get the message "Finder wants to make changes. Type in your password to allow this. Why ? and how to to stop this request ?

There should be nothing native to the OS X which would ask for a password
or other information on a restart, unless accompanied by the traditional login
box with your user name.
There are adware or marginal products that could be called malware (bad)
that would impose their presence and some items that could have been
downloaded by accident or through some corrupted free software site; of
those some could ask for and gain permission to go through your Mac
and maybe even run in the background to do other nefarious misdeeds.
You could see if startup in SafeBoot allows you access past that the Completer.
Since I don't have a pile of helpful article links on how to resolve various issues
I'd be looking them up one way or another.
There are some helpful items in the site http://thesafemac.com - see Tech Guides
listed (adware, malware, & performance) plus a link to the adwaremedic page.
Also, Apple support has a helpful page on how to remove adware and other bits:
•Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support
Hopefully this helps somewhat.
Good luck & happy computing!

My daughter is a college student. she needs to write and compile c programs on her mac for a class this semester. what is the best place for her to start to get the correct compiler etc. to use ? thanks

If you know that you will not be asked to design GUI interfaces, and the C programming course will adhere to command line compilation environments, then get the Xcode command-line developer tools, and skip the extra complication of Xcode until you absolutely need it. Apple has kicked GNU C to the curb and is rightly so, using Clang/LLVM compiler technology.
Sign up for a free Apple Developer account using your Apple ID, and then visit the Mac Dev Center, and towards the bottom of the page, you will see additional downloads. Click on the associated, all down loads link. Know your OS X version beforehand, as the command-line tool releases are tied to general operating system versions, and the most recent Xcode version. That said, there are currently two March 9, 2015 command-line tools for Xcode 6.2 — one for OS X 10.9 Mavericks, and the other for OS X Yosemite.

Our website was set up 10 years ago with Macromedia Dreamweaver. Can I download up to date Adobe Dreamweaver and still access and make changes? I do not have the old software

Anyone can help answer this? Thank you,

Most web site files can be edited using a simple text editor. It is not clear to me what you are looking for when you ask if you can download up to date Adobe Dreamweaver and still access and make changes. You certainly can, but you need to purchase the software to do so if you mean you want the latest versions.
The most current version is available thru a subscription basis.

At this point you have the option of keeping a device optimized version (lower resolution version) of your photo on your phone while iCloud stores a full resolution version. Or keeping the full resolution version on both your phone and the iCloud. If you delete the photo on your phone it will be deleted on the iCloud. I know, bummer. Also it should be noted that the photos app and the library are still in beta and to this point i see why. I would use dropbox or a smiliar app for off device storage.
So far this is how it has been working/not working for me. Whether or not I choose to keep originals or optimized on my phone it will only keep the originals and it has only been uploading lower resolution versions of my photos to the iCloud library. Seems to be working in reverse.
Again these are still in beta so i am hopeful that this will be fixed in the near future.
I hope this helps.

My partner deleted my itunes (10) library. I use a WD external back-up and retrieved my itunes library, but when i try to play a song i get the message 'could not be used because the original file could not be found Would you like to locate it?'

My partner deleted, by accident my itunes library. I have an iMac 10.6.7, Itunes 10. I use an WD passport as an external back up and retrieved my itunes library but now get the message "could not be used because the original file could not be found. Would you like to locate it?" so itunes is not recognised the exclamation marked songs, how do i get the retrieved files recognised. At times I get fed-up with Apple blocking files being used, although I like the product its restrictions are so silly!

You not only have to retrieve the library file from the backup drive but the actual music files (usually stored within the "iTunes Media" folder) as well.

Clarisworks, you need Appleworks, which will only work with Mac OS X10.6.8 or earlier. See this tip if you must go newer. Mac Pros with newer hardware configuration than July 20, 2011 can't use Mac OS X 10.6.8 or earlier without this tip and then it would be Mac OS X Server. I'm not sure if the new black Mac Pro supports that configuration or not.
iPhoto, there is an iPhoto for all versions of Mac OS X.
iTunes, there is an iTunes for all versions of Mac OS X. Note with iTunes versions 11 and later, which are needed for syncing with iOS 7 or or later, you will lose coverflow, if you liked that feature. Sadly you can't run an older version of iTunes from within Mac OS X 10.9 or later.
Sketchup: http://help.sketchup.com/en/article/60107 shows the versions that will work with intermediate Mac OS X versions, and this shows the latest version: http://help.sketchup.com/en/article/36208 be sure to click on the operating system you choose to use.
GIF - Viewing GIFs Apple's Preview can do that. Editing them, I like http://www.lemkesoft.com/ Graphicconverter.
DMG is able to be opened by all versions of Mac OS X. This are just "disk images" which store programs on a virtual disk that will open when double clicked. Frequently you'll find the installer of the said program inside. To find out if the program itself is compatible with 10.7 through 10.9, see http://www.roaringapps.com/
Otherwise see the resources on:

If you end up deciding to stick with Snow Leopard.

How do I fix the problem?

Hi Ali,
You can download Acrobat 9 Std. from: https://files.acrobat.com/a/preview/8d640488-4a92-4f7d-b50b-d8eb7f96bff8
