Need some assist - Load button for file retrieval

Hi All
I am trying to retrieval a simple text file to memory but some how I can only load the first item to memory.
I am a beginner, hope some one can guide me
Thanks
      * This method initializes jButton3
      * @return javax.swing.JButton
     private javax.swing.JButton getJButton3() {
          if(jButton3 == null) {
               jButton3 = new javax.swing.JButton();
               jButton3.setSize(87, 33);
               jButton3.setLocation(265, 228);
               jButton3.setText("Load");
               jButton3.addActionListener(new java.awt.event.ActionListener() {
                    public void actionPerformed(java.awt.event.ActionEvent e) {
                         try{
                              FileReader fileInStream = new FileReader(FILE_NAME);
                              BufferedReader dataInStream = new BufferedReader(fileInStream);
                              getIvjDefaultListModel().removeAllElements();
                              String currentItem;
                              while((currentItem=dataInStream.readLine())!=null){
                                   if (currentItem.length()!=0)
                                   getIvjDefaultListModel().addElement(currentItem);
                              fileInStream.close();
                              dataInStream.close();
                              getJList().setModel(getIvjDefaultListModel());
                         catch(Throwable exe){
                              System.out.println("actionPerformed(Failed to open file)");
                         System.out.println("actionPerformed(Tried to load items from file)"); // TODO Auto-generated stub actionPerformed()
          return jButton3;

Do you really want the close the stream inside the loop?

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

I need some Important Trigger Programs for Objects

I need some Important Trigger Programs for Objects.
If the program includes the V-array appln, that would be better to.

There are some drawbacks, running Windows 7 (only) on a Mac via Bootcamp yields less than stellar results, especially with the Retina display.
And of your traveling, the Mac's high power needs (especially the Retina display) and lack of removable battery are going to be a serious issue. The Retina display is glossy, not ideal for viewing on the road and in varied environments.
CS4 won't run on the OS X version that comes with a Mac, so your looking at purchasing CS6.
Support for Windows is more widespread than for Mac's, also if you ever need to redownload OS X to fix a issue, requires a fast reliable Internet connection of the broadband kind.
If your running Windows on your Mac, you can expect to be on your own and not get support as easily as if you were running it on a regular PC.
If you can't afford to keep up with CS upgrades, then you shouldn't be considering a Mac because there are more paid upgrades on that than on Windows 7, it's like a annual nightmare.
IMMO your still better off on a decent, 1920 x 1080 res, matte screen, removable battery (with extras), Win 7 Pro i7 machine (Pro+ runs XP programs) which will stay like it is and get security updates until 2020.
OS X changes every year and if you don't upgrade, + all your third party software, then about 3 years later your left behind for updates.
Also you will have to buy Win 7 to run on your Mac, the OEM disks won't work.
If your trying to budget, then a Mac is certainly not for you.

Need some assistance in binary streaming and reading

Hi,
altough I studied the examples delivered with LabView (my current version is 6i) I have some challenges to face and I hope someone could help me. This challenges
may be simple for professionals but I'm not already that experienced. I have an one channel AI input via a DAQ-card (E-series) and I want to write it to a binary file with only the really necessary headers. The data then stored in the binary shall than be displayed after user request to a graph and my client wants to have the possibility to srcoll through the hole stored data to seek some charakteristiks and then mark the area of interest with cursor to move this area to another graph for further analysis. My program is structured in a way that in a whi
le loop I wait for user interaction i.e. buttons for saving and displaying data. It's for that, that I think I have to split the binary streaming in a sub-Vi that makes the needed preparation and another sub-Vi assosiated to the first that makes the file writuing and thats placed within the loop described above. Maybe I'm with my thoughts on the woodway and someone has better ideas. I tried many things but the result were always frustrating. I would be glad someone could give me some hints based on experience, and not just saying "Look to the delivered examples" as I already read in questions from other users. Thanks for your support.
Chris

I think you're going at this in a good way. One issue I see is that you are using version 6i and waiting for user input. Since Event Structures were not available in 6i, you will have to poll for user input and that could make your application slower. An upgrade to 6.1 would help you there.
Besides that, I like your ideas. If you're sticking with 6i, use a case structure inside your while loop which executes a particular case based upon which button the user pressed. Then, in these cases, call the subVIs which you built. I hope this helps out.

PC upgrade...... Been a while....... Need some assistance.

Hello,
It's been a while since I upgraded my PC and am a bit behind on things.
Here's what I installed:
OS: XP Professional
CPU: Phenom 9600 2.3Ghz AM2+ x4 L2+L3=4Mb, 95W, 65nm
MB: MSI K9N2 SLI Patinum nForce 750a, BIOS=V3.5 current
RAM: 4GB Patriot Viper EPP PC-6400 800Mhz (4,4,4,12)
Video: 2x GeForce 6600GT 512MB PCI-E
PS: New 550W
Everything on "Auto" in BIOS.
The good news is that I'm using it now. The problem is games, it seems to be slower than the old configuration?
I have to turn everything down to minumum or to off to prevent lag. Real disapointed having invested time and $$$ to upgrade.
There must be something not set right. The old configureation was a AMD dual core with one video card and 2MB of memory. I swiched from SLI mode to one graphics card and it seamed to be the same? I mean.................... damn........... what gives? Where's the bottle neck, Anyone with any ideas????????
Also - What is SVM and it's purpose, can't find it with search.
I can't adjust voltage in BIOS. I can highlight but can't change?

The GTX260 I have requires min of 500W with 38A on a 12V rail. It has (2) 12V rail connections.
That's 550watts 38A suggested system wide, as Mike said, containing a card of that design, but nonetheless you done good. Who knows what you'll want to add to your system in the future and what type of demands they'll place on your PS. That supply will do it.

I'm wondering with all the heat being generated now I might need to get better cooling for the PC, CPU (stock fan from box)
What are temps? Idle and full load for cpu, gpu, and chipset? Use some type of burn in test to load system to report full load temps. Folding@Home works very well to stress test and it furthers medical research to boot.(Consider joining MSI HQ's team) Monitor temps voltages, timings, and temps with Everest or the like. Other programs of interest are HW monitor, CPUZ, Core Temp. Check out the stickies in the overclocking forum for links to these and other programs that might interest you. You sir, are about to have a whole lot of fun.

Switching from Comcast - Need some Assistance

I have been a Comcast subscriber for many years now, but have heard that FiOS is supposed to be better. However, there are a few things that make me somewhat ambivalent about switching. First off, I've had Comcast for years, and have had a few issues with them, but not THAT many. So I don't know if it'd be worth it to change, since a new provider might not be as good. But also, I noticed that carriage of local channels is different on FiOS than it would be on cable, since I would assume it would be the same throughout the entire market. For instance, in the Boston area, some communities near the Rhode Island border receive Providence channels as well as Boston on cable, but not on FiOS. I've also heard that FiOS' On Demand selections are rather different. I know there's tons of movies on demand, but what about TV shows, and local events? I also saw a post here from someone who doesn't get local weather on their system. So I've heard that in a way, FiOS is more like satellite than it is like cable.
Anyway, I'm sure that many of you here who now have FiOS TV have switched from cable, and let me ask you this: Have any of you ever considered switching back? Why, or why not?

fair question.
I switched from comcast to verizon at the end of last year.
my sole reason for switching was due to savings of $40/month. To me, the quality, speed, and service appears to be the same (or hardly noticeable to make a significant difference).
the main advantage for switching to FIOS is money. Some small advantages FIOS has over Comcast is some of their local networks on-demand content. I believe that Comcast only provides CBS while Verizon offers ABC, NBC, and CBS (neither carry Fox on-demand).
the main disadvantage to me is that you do NOT need a set-top box to get all of the channels with comcast. a simple splitter will suffice. for FIOS, you need to rent the box for each tv or else you will not get a picture. another disadvantage is that the free movies on Comcast are far more vast and far better than Verizon. However, Verizon is aware of this and are slowly adding more content throughout this year.
As for customer serivce, it's hit or miss with both. You'll read many horror stories and happy stories from both sides, so to me, that's almost a risk or expectation with any paid service.
that being said, FIOS has made considerable advancements in technology in their internet and cable service over the past few years while keeping the costs to the consumers down. comcast, on the other hand, has not made any significant technological advances (at least none that I know of, although they do claim to double your internet speed every year, but so does everyone else).
thus, even though I must rent a box for each of my 6 tvs, I'm still saving $40/month, but we'll see what happens when the 1-year promotion ends this december.
You've got to be very careful if you don't know where you're going, because you might not get there. --Yogi Berra

No OK Button For File Extension In Preferances! Help!

I have an external hard drive, which I put all of my media on. However, whenever I put a CD or download from the Itunes music store it doesnt save on this hard drive. I found a way to change where the files go for when I download or import through Itunes (Edit, Preferances) but there is no OK button at the bottom of the screen so the only thing I can do is X it out and it doesnt save any changes. Please help, my computer is too old, it holds 9 gigs, I can't save the music I listen to on it, so please help, thanks.

Hello,
please see the answer in

I need some help on ACS for a programmers

Hi all,
Kindly I need someone to guide me how to get the below information for our programmers, our company now they need to integrate our billing system
With ACS which already running. the setup running is :
We have cisco Access points managed by Access controllers with two SSIDs ( USERS , GUESTS ) and the access controller is configured as Client on ACS.
We need to make new setup for Guests, any Guest want to access to Guest wireless network (SSID: GUESTS) I need to create the account on Billing system, our programmers asking me to provide them the DB structure of ACS 5.0 and all information needs for integration between the billing system and the ACS.
Note: we already have another SSID (USERS) for company users and it is running fine and accounts managed directy by ACS ( no need to change the setup).
Goals: The billing system will create the Guest accounts and the account information to be automaticly added to our ACS.
I realy don't know more about ACS and this requirements.
Anyone can help me to acheive this goals.
Regards

Jack:
Yes you can any program to do tasks with ACS.
Look into this:
http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.3/sdk/cli_imp_exp.html
There seems no developer's guide for ACS 5.0. I think you have to upgrde anyway preferably to 5.3 or 5.4.

My father gave me his old Mac Book, with OS 10.5.8. I need the version 10.6 for it,despite me searching for software updates daily,it says there are no updates. How do I update it? Will I loose any Save datas from Musics and stuff? By The Way, I live in Brazil.

Niel, folks, hi. You mentioned the last time you perfectly helped/assisted me bout MacDrive Apps for file retrieval, what's the specification? Thanks

I've had my WD external hard drive formatted to MAC OS Extended(Journaled). No issue bout it, all good. I have my old files saved on a desktop hard drive other brand. What specific MacDrive Apps do I need to download on the desktop for me to retrieve my old files back to my external hard drive? Thanks

HT1384 My lock screen/power button on my iPod Touch is broken, and I need some assistance.

As the title suggests, I can not use the lock screen/power button on my iPod Touch, it is broken. I can use Adaptive Touch to turn the screen on and off at will, and also turn my device off. But if I turn it off, I don't know how to get it to turn back on. Could I just plug it into a charger and turn it back on, or would I need to plug it into my computer? Please help, in a few days I won't have access to it for 9 weeks, I need immediate help.

If you power off the iPod, it will turn back on if you connect it to a charger like a wall charger or a computer. I just checked with a charging source to confirm. I knew it did it with a computer.

Need some help with button JavaScript for Save As event.

Hi,
I'm using Adobe Acrobat X Pro and am completely new to scripting forms in Adobe (completely new to Adobe Acrobat as well!). On a form there is a save button that opens the Save As dialog by using a trigger (Mouse Up) and action (Execute a menu item - File>Save As...>PDF...) and this works fine, however, I want to now use javascript to modify this button's behavior so that is uses a trigger (Mouse Up) and action (Run a JavaScript), and I want that JavaScript to combine the text values from two form fields (a location Dropdown and a date Text field) and use this concateneated string + ".pdf" as the filename when it opens the Save As dialog. Make sense?
This is what I have added to the button as a JavaScript so far I am using a test string at the moment ("NewFile.pdf") and will add the concatenated string to the script after I know the script is working as it should.
var newFileName = "NewFile.pdf";
var pathArray = this.path.split("/");
pathArray.pop();
pathArray.push(newFileName);
this.saveAs(pathArray.join("/"));
Two issues so far:
1. When I click the button nothing happens, no Save As dialog or anything.
2.When I check the button properties under the Actions tab the Select Action property shows "Execute a menu item" even though I previously selected "Execute a JavaScript"
Thanks for any help!

Thanks guys, I appreciate the response! If I can bypass the Save As dialog and save the file to a default location using a file name that is contructed from two form field values then that would be perfect. I definitely think it is feasible to have a script file installed locally on each users workstation. I don't quite understand about folder-level security, etc. yet but am eager to learn how to do this stuff if you can give me gentle push in the right direction! Thanks!

New Safari 3.0.4 Won't Load web Pages, Need some Assistance.

I Too have installed and updated to 10.4.11 from 10.4.10 and too am having problems with the new Safari 3.0.4 ... My Problem like all the others, is for me, Safari isn't loading any web Pages, I just get a blank Page and nothing is happening, its just sitting there doing nothing. What could possibly be the problem and what should I do??
Please someone help Me soon, I do have 2 back up web browsers but I prefer Safari because all my bookmarks are on there.
I wish Apple would fix this glitch before putting out the new Safari, because alot of people are having problems with the new Safari, is there a way that we can contact Apple and complain to them about Safari 3?
Thank you,
Trisha Foster

Im Glad you had solved your problem but I am still stuck on mine, I tried to see if I had a PicLens Plugins in my input manager Folder but I don't, what I have instead is a Folder called Smart Crash Reports info/smart cra...rts.bundle and info. icon document.
Safari 3.0 gets crashed by various 3rd party add-ons ("enhancer" programs and also InputManagers) which are doing things that are incompatible with it.
Based on what is working for other people in this forum, I think you should delete (or move to the Desktop or something) anything in your Mac's (global) /Library/InputManagers folder and also the Library/InputManagers folder specific to your logon to the Mac.
Also delete or uninstall anything else that is any sort of Safari enhancer/speeder-upper/skinner/prettifier.
If that doesn't work, it's possible that some time previously you had some add-on/enhancer thing which directly patched the insides of the Safari.app (ie directly changed the Safari application in your Applications folder, rather than installing itself in some other folders like InputManagers (and Apple has tried to do a non-destructive/merging update and left those unexpected and now incompatible modifications merged-in). In that case there are some instructions posted a couple of days ago on www.macfixit.com how to fully delete the Safari application and reinstall a completely fresh copy of it from the Combo updater for 10.4.11.
Anyway, I'd say the best first step as already posted here is to get rid of anything that is an InputManager or otherwise an "enhancer" to Safari and see if that resolves it for you.
