About to use my tree for firewood
I was wondering if someone could maybe clue me into a problem that I am having with my DefaultMutableTree. See, I call a recursive method to get the file system of the computer, which is what is added to the tree. So the user is looking at a tree structure of the file system of their computer. My problem is that when I compile and run my program the tree shows up fine, with no hitches. I have given my code to other friends, and for some of them it does not show up, and throws a null pointer exception at the internal interface of this recursive method. I was wondering what might be causing this? My friends that have problems with the code are running either WIN XP, or Mac OS 10.1.4. Here is the code for the initialization of the tree (This will look ugly on the post, so I would hope that you would take the time to copy and paste this into your editor :D)

it's likely that it's running into a file or directory that it can't list (in my case it was a mount on a different directory ntfs is kinda cool)... SO... to handle that problem I just put the whole method in a try / catch block
it was just the method unfold ... the fix returns a blank treenode... it should probably return null and the caller should see that as a sign to not add it to the tree...

Folder Chooser reference (which uses a tree for selection)
is there a recommendation for a folder chooser which uses a tree for selection? all i've found so far are either:
* 3rd party folder choosers
* the file open dialog box of java where you use setFileSelectionMode( JFileChooser.DIRECTORIES_ONLY);
i can't believe there is currently no folder chooser which uses a tree for selection in standard java. so probably i didn't find it. before i write my own, i thought i'd ask.
thanks for the help!No, it doesn't exist in the standard Java API. What's wrong with third party solutions, especially when some of them are open source? Google found quite a few.

I'm confused about buying used smart cases for iPad mini 1, 2, and 3.
I'm trying to buy used smart covers for the iPad mini 1, 2, and 3 but I'm not sure which smart cover versions will fit which mini.
So far, in pink, I've been able to find MGNN2ZM/A and MF061ZM/A. But I want all the other colors too.
MacMall.com says MGNN2ZM/A is compatible with iPad mini 1, 2, and 3 and MF061ZM/A is compatible with iPad mini 1 and 2. (Apple doesn't provide the part numbers on their web page)
Basically, I could really use a list of iPad mini, iPad and iPad Air accessories' parts numbers, and the device/cover compatibilities, if such a list exists.
Eventually, I want to buy smart covers in every color for iPad 1, 2, 3, 4, 5 (Air), and 6 (Air 2).
Thank you for your help in advance ^^Hello there ctemple,
That is a great question, thank you for taking the time to contact us. I am sorry to hear your phone is on it's last leg and not working as it should be. I know how important it is to have a working device at all times so will be more than happy to assist you today.
Great news on our Verizon Edge program you can upgrade to pretty much any phone in our lineup. You pay a small installment every month over a 24-month span on your bill instead of paying full retail or the two-year pricing all at once.
If you like you can view additional information about our Edge program by going to http://vz.to/1kqnEzS
Please let us know if you have additonal questions or concerns. Have a great day!

If you at least know your Apple ID you can go to this Apple Support page.

Click on Forgot My Password.
Try to recover or set a new password. Hopefully your email addresses still get mail from Apple. -
Hello ,
I want to ask some question about ipads \
How powerful is the iPad?
How useful is it for reading books, newspaper or magazines or for surfing the web?
Can you identify any shortcomings of the device?
please help meit's less powerful than your average computer. THink of it like a netbook but with a better processor.
It'll do fine for surfing (although if you browse a lot of flash based sites you will need to get a third party browser since safari doesn't accommodate it)
You may do OK on reading books, papers or magazines, especially if they have apps, but the ipad's screen is backlit, so it doesn't work well outdoors and you may need to fiddle with the brightness so that you don't get eye strain (it's just like doing too much reading from a computer screen)
I would say the biggest short comings are data transfer. Apple's preferred work flow is that everything is done via iTunes or the internet....well people dont' always have 100% reliable always on internet access so you can find yourself in a situation where you can't get things on/off the iPad.
By and large, it's a good device for day to day stuff, but is not a computer replacement. -
Since updating to LR5.5 it crashes about every 5-10 images while working in the development module. Computer is PC Windows 7 Home Premium. I have been using this computer for several years with zero problems. Is this related to the updating? What is the fix?
Do you get an error message? If so, what does it say?
Do you get a Blue Screen?
Does something else happen? -
I Use the last FCX but I have a prob when I export (share) to dvd the result is over 4GB for a single DVD is about 6 to 9 Gb for a short film of 1h so what can I do to fix this thnks
These "Share" files are accessed and used by the Create Disc app.
Create Disc is buried in the FCP X package.
Applications>FCP X>Show Package Contents>Contents>Plugins>Compressor>Compressor Kit.bundle>Show Package Contents>Embedded Apps>Create Disc
I'm wondering if having the Compressor Application on a Mac makes a difference to having just FCP X on a Mac and the use of the Sharing feature.
I have Compressor loaded and find that DVD and Bluray burns from Share without any glitches as some are experiencing.

My macbook from 2008 which I bought used worked fine for 3 weeks and then suddenly it started restarting and now it restarts, goes to grey apple screen and a code saying something about a kernel panic appears and it restarts again and again. Help?
Restart the computer and immediately hold the Option key down.
Select the Recovery partition and continue.
On the next pane, select Disk Utility and continue.
When DU opens, select your hard drive in the left column, click the First Aid tab, the click Repair Disk.
When that is done, quit DU and restart in the usual way. -
Use external image for tree icons
Hi all,
having searched extensively with probably the wrong keywords, i'm hoping someone can point me in the right direction.
My app has a tree control that gets built by reading an Ini file, the icons get populated with custom images from a directory. I'm trying to find a way to be able to interchange those icons after the executable has been built. The current way that i put the icons in the tree is simplistic. the names determine where in the tree they go... i.e. icon_1.jpg , icon_2.jpg , icon_3.jpg ... become the first, second, and third icon.
i just don't want to have to rebuild the app every time a customer wants to replace the icons.
any tips?
thanks in advance!I'm not very original, I'm using a tree toolkit i found on LAVA written by Norm Kirchner. http://lavag.org/index.php?app=downloads&showfile=27
and a library i found on NI : http://digital.ni.com/public.nsf/allkb/89A75D98771F2FB686256F350055EB3A
See the .zip at the bottom of the page, it has an example vi.
It does in fact use the "Read JPeg File" vi's.
You'll see in the "Load Symbols.vi" that it takes as input, a directory where your custom symbols are located. Is there a way to keep this directory outside of the executable when the application builder compiles everything together....???? Like maybe in the /data directory?
I've only been using the app builder for a couple weeks so I'm not that sharp on those little nuances, but the more we hash this out, it seems like it should be possible.

Help me. I did not use my ipad for about a month.Now that I turned it on after trying to charge it for many hours, it just would not turn on, just a black screen with sometimes an apple logo blinking, brought it to repair shops, said they could not fix it, please help

I used Version : 4.2.1 (8C148) but I want to update New version because some application need 4.3 or 5 .... please tell me about to update new version for my iPhonoue 4. Thank you.
Start iTunes on the computer you normally sync with. Connect your phone. Select your phone in iTunes on your computer and select the General tab in iTunes. Then scroll down to check for updates. iTunes will update your phone to the latest version of the iOS that is availablele.
