JfileChooser limited to one file

JfileChooser limited to one folder.
Is there a way to set the look in option to one folder without showing all other accessable folders and subdirectrys.
Thankyou

Look at the setFileFilter method in JFileChooser. You can make a FileFilter that won't show directories.
You'll also need to call setAcceptAllFileFilterUsed(false), so that that filter will be unavailable.
However, there's some more problems that I'm not sure about.
If the user types *.* into the file box, they can still show all files. Also, on Windows at least, there's a button to go to the parent directory. You'd need to fix that somehow.
Alternatively, you could implement your own file list.

  • Multiple databases in one file: a small snafu

    Hello everyone,
    Opening multiple databases in a single file is an administrative convenience. It is well explained in the manual (see db/docs/ref/am/opensub.html). Normally, there is little difference between databases in their own physical files or grouped together in a single physical file. There is one small sentence in the manual that says the following:
    (begin fragment)
    However, since multiple databases in a file exist in a single physical file, opening two databases in the same file simultaneously requires locking be enabled unless all of the handles are read-only. As the locks for the two databases can only conflict during page allocation, this additional locking is unlikely to affect performance.
    (end fragment).
    I didn't pay attention to it, except the "unlikely to affect performance" part which told me that I wasn't to worry about it. The sun was shining. Life was good.
    And I was wrong. It was one of those "epic bug quests" I had to embark on, only to realise that it may not be a BDB bug, but my carelessnes. Nevertheless, I'm left with an uneasy feeling which I would like to explain here.
    Consider BDB configured as a concurrent data store.
    There are 2 threads. The first thread has the following pseudocode:
    cursor1 = db1->cursor(...)
    while(cursor1->c_get(... DB_NEXT...))
    // 1
    cursor2 = db2->cursor(...)
    while(cursor2->c_get(... DB_NEXT...))
    The second thread does only the following:
    db3->put(...)
    db1, db2 and db3 are all distinct databases. All cursors are read-only (the cursor implicitly used in db3->put is of course a write cursor).
    While the first thread is running, the second thread executes db3->put(...) at "//1".
    Question: what happens?
    Answer 1: if db1, db2 and db3 reside in different physical files, nothing special happens. Everything proceeds as it should.
    Answer 2: if db1, db2 and db3 reside in the same physical file, both threads block "sometimes".
    The "sometimes" used here means "when the put operation in thread 2 needs to allocate a new page".
    Reading the BDB source code is extraordinarily difficult (which says more about my limitations than about the clarity of the code) but here is what happens, as far as I could determine:
    (thread 1) cursor1 needs and acquires a read lock on db1
    (thread 2) db3->put needs a write lock on db2 to allocate a new page. Since db2 is in the same physical file as db1 and thread 1 already has a read lock, thread 2 waits until the read lock is released. Thread 2 blocks.
    (thread 1) cursor 2 needs a read lock on db3. For some reason, BDB detects that the another thread is waiting for a write lock on the physical file, and thread 1 blocks.
    Both threads block waiting on each other to complete.
    I suppose the system is the way it is to avoid starvation, but there you have it: be careful when you're lumping together multiple databases in one file!
    Anyone who can clarify or confirm this is welcome.
    Vincent

    I had experienced a similar problem. I run multiple process. Each one of them starts a transaction that does db->put and db->pget to its own database (which also has a secondary index). When each database is in a separate physical file there is no problem but when I put all databases in a single file the processes start to dead-lock.
    The following combination of options solved the deadlocking problem:
    - use serializable isolation level instead of snapshot, i.e. do not pass DB_TXN_SNAPSHOT to txn_begin
    - do not pass the DB_NO_WAIT option to txn_begin
    - use Btree instead of a Hash
    Hope that helps.

  • File Download limited to 4 files at a time... the rest are pending...

    safari version 2.0.3 (417.9.2)
    File Download limited to 4 files at a time... the rest are pending...
    - it did not used to be this way -
    - is there a way to up the limit to more than 4 things at a time - if so how?

    I believe 4 is the Safari limit. To be sure, go to your User Library>Safari folder and trash the downloads.plist file. Restart Safari and try multiple downloads. Trashing this file resets the Safari Download function and clears any corruption in the file.
    If 4 is the limit, you'll have to try a 3rd party application such as SpeedDownload, which offers much more download flexibility and features than Safari.
    One word of caution, if you try SpeedDownload but decide it is not for you, make sure you uninstall all of its components, especially any in your Internet-Plug-ins or InputManagers folder in either the Main or User Library, and the YazSoft preference file in your Preferences Folder. I know the app. comes with an uninstall feature, however, always good to double check.

  • Lightroom - Photoshop Integration breaks for more than one file

    This message is for those of us who process lots of images. I just spend a n afternoon working with Lightroom 1.0 to process the 900+ images taken at a sporting event over the weekend. My task is to find the keepers, and then run a custom action in Photoshop on every one of those files to prepare the files for delivery to the client.
    Its pretty clear anyone doing serious noise reduction or sharpening work needs to have PS right now, but even if those limitations are addressed, let's assume there's always going to be something that needs to be done in Photoshop.
    The problem is the current integration of Photoshop and Lightroom seems to be based on a single file, i.e. there's no batch capabilities, but I need to be able to set up and run recorded Photoshop actions on 900 files! (OK, only half were keepers, but you get the idea.)
    The workaround is to export all of the files out of Lightroom into a directory, and then run a batch process to create a second directory of the processed files. I now have 900 files that aren't in Lightroom's database! Unfortunately Lightroom doesn't recognize files on the hard drive, and so if you're using Lightroom as a file manager, in six months I'll never know those post-processed files are even there.
    Sure, I can delete the first directory, but I'll definitely want to keep the final files around for later. The only option is to then run another import on the final directory, which creates more down time.
    The problem is the chances of getting out of sync are huge, plus there's no association between the original and processed versions as happens when you edit from within Lightroom. (In that case the original and processed are stacked.)
    Now, the 1.0 version is amazing, and I consider the program to be one of the best programs ever designed. This is just a request to consider tackling this problem in version 2.0.

    Yes, that's a big improvement in 1.0. The only problem is it only works for one file :-(
    Overall I've found stacking to be less useful in other contexts, unfortunately. For me at least its been easier to just go through all of the photos initially to rank them, and then only show the candidates to send to clients.

  • So what exactly does limited to "one app" mean with a Pro account and the new prices?

    So it seems Pro has dropped in price but it is now limited to "one App".
    So what exactly does that "one App" mean?
    Only one tablet version or one phone version for a certain title?
    Or you can have a tablet & phone version including android & iOS for that one title?

    I think that everyone received it just now…
    Changes to Adobe Digital Publishing Suite, Professional Edition
    Effective immediately, all customers who newly purchase or renew Digital Publishing Suite (DPS), Professional Edition, will be able to publish only one app per license of DPS Professional Edition.
    Under this policy change, Professional Edition customers can publish an unlimited number of issues (.folio files) to a single app and distribute those issues based on purchased fulfillment bundles.
    An app created with a single license of DPS Professional Edition can be distributed to any or all of the marketplaces that DPS supports, including the Apple App Store (and Newsstand), Google Play, Amazon Appstore, and the Windows Store.
    In conjunction with this policy change, Adobe is reducing the price of a Professional Edition license to $4,800 USD annually (€3,600/¥480,000) or to $400 per month (€300/¥40,000) and will include 1,000 fulfillments annually. The number of fulfillments included with a monthly subscription remain unchanged.
    This policy does not apply to test or demo apps published using Professional Edition. The one-app-per-license policy applies only to an app published to a supported marketplace(s).
    If you are an agency, upon your renewal or purchase of Professional Edition, you can create only one app per Professional Edition license. If you have multiple clients for whom you are creating apps, either you as the agency or your client must purchase a Professional Edition license for each app published to a supported marketplace(s).
    If you are an existing Professional Edition customer and choose to renew your Professional Edition license at the end of your annual agreement, these changes, including the lower price point and 1,000 fulfillments, apply at that time. These changes do not apply to your existing DPS Professional Edition agreement and take effect only if you renew your license.
    DPS Professional Edition customers can continue to create unlimited Single Edition apps, which is unchanged under the new policy. A Single Edition app is defined as an app that includes one built-in or embedded folio.
    If you expect to publish three or more apps annually, we encourage you to contact your local reseller to discuss pricing for a multi-year Enterprise Edition license.
    Enterprise Edition offers additional functionality and benefits not available through Professional Edition. These include app customization, integration with back-end business systems, in-app marketing tools, targeted content based on user entitlement, and the ability to publish apps privately.

  • Can I load Premier Elements 12 on my two laptops or am I limited to one device?

    Can I load Premier Elements onto my two laptops or am I limited to one device?

    Trevorg
    What computer operating systems are involved and are you installing from an installation disc or installation files from a download. That can impact the answer. But, the generalization is that Adobe allows you to have the same purchased activated serial number on no more than 2 of your computers. But, you are not supposed to run them at the same time.
    Any questions or need clarification, please do not hesitate to ask.
    Thank you.

  • Help! Audio recordings are limited to a file size of 2 gigabytes.

    Hi, I have been having an issue with garageband lately. I record for about 10-15 seconds and I get this error message
    "Audio recordings are limited to a file size of 2 gigabytes. This recording has reached the file size limit. Recording will stop, and the recording up to this point will be preserved."
    I have no other tracks in the project and have over 100 gigs free space on my Hard Drive. I have unchecked the Auto Normalize Volume box however it made no difference. I have not seen any one else with this problem on forums. I have tried recording with the input jack, an external usb recording interface, the built in mic and for each of these I get the same message. I also had this problem with Garageband 10 so I upgraded to 11 with no luck and the same message appearing. I have called apple care and gone to the apple store and no one seems to know the solution. Can someone help? Thanks!

    I'm having the exact same problme, with a few more pop ups appearing to boot.
    I don't have a solution I'm afraid, but have found that just clicking OK (or cancel, depending on the pop up) will allow you to continue with your recording.
    Annoying as ****, but still workable.
    I shall endeavour to find a solution, and report back

  • Different Scroll bars in one file

    I've manually customized the look and feel of the scroll bars for scroll pane component and it works fine. I've two different files that have different visual styles for scroll bars. Now I want to merge these two files meaning I want to have one file with two different styles of scrollbars co-existing. I can resolve the naming conflicts but both of the them are using same asset names and action scripts (I think in the class definition).
    So basically my question if how can I have two different scroll bars implemented in one file?
    Many thanks

    You can make the clip that you want to play at 2 fps seem
    that way by just making it longer. Alternately, you could use a
    timed tween.

  • I have two different itunes music files on my computer.  How do I combine them into one file?

    I have two different itunes music files on my computer.  How do I combine them into one file?

    I don't think so. The only other ID I have is a developer id, and I didn't get that until several months after I got the phone. In addition purchases I made from the App Store onthe phone would sync up with It unes on the Mac meaning it would be the same id.
    However I looked at the AppStore on my phone while it was connected to the Mac with iTunes open, and now the balance has changed to the same as the others.

  • I have three websites in one file. How do I separate them into three individual files?

    I have three websites in one file (Domain.Sites2). How do I separate them into three individual files without taking the site down or loosing files?

    Duplicate the domain file 3 times (keeping the orignal as a backup).  Name each domain file for the website you want it to contain.  Then open each domain file and delete the two sites you don't want it it. 
    Since you're running Mt. Lion you'll need to read the following in order to be able to open the different domain files.
    In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
    To open your domain file in Lion or Mountain Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application. 
    do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
    tell application "iWeb" to activate
    You can download an already compiled version with this link: iWeb Switch Domain.
    Just launch the application, find and select the domain file in your Home/Library/Application Support/iWeb folder that you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
    WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder.  So rename your domain files once they've been created to something other than the default name.

  • Can not color label more than one file at a time

    Hi,
    I've had this problem since 10.6.6-ish, i can not color label more than one file at a time in the Finder.
    Wether i select two, twenty or twohundred only one file gets color labeled.
    It doesn't seem to matter if i assign a color label through the File menu or right click > label.
    Figured a re-install might fix this but it hasn't (even a clean install without restoring any kind of backup).
    Does anyone else have this issue and/or a fix for it?
    Thanks,
    Jay

  • Scanning multiple pages into one file using MAC

    How do I scan multiple pages and save them into one file or document using a MacBook Pro laptop?  My printer is an HP Photosmart 7520.  When I use this printer and scan from my PC, it does allow me to scan multiple copies and save as one document by just adding pages as I scan.  When I scan with my MacBook Pro, it scans each page, however, I don't get any option or choice to save as one document.  It automatically saves each page as a separate document.

    Try scanning from your Mac. Use Image Capture app in your Applications folder.
    Click once on the scanner on the left side, then click on Show Details along the bottom. Along the right side you will see LOTS of options for scanning and saving.
    One of those is Format, make the Format PDF.  Just below that will be a check box allowing you to scan multiple pages to one file.

  • Scanning multiple pages into one file

    I am scanning several pages that need to be in one file so that I can email that file. My printer has a flatbed where you can place only one page to be scanned at a time. A friend of mine said that it should ask if I want to scan another page but it doesn't.  It simple imports it to "My scans."  There are too many pages to try to email one at a time. I need it in one file. Can anyone help?

  • Scanning multiple pages to one file

    I have a C310a All in One printer/scanner.  My computer uses OS X 10.9 and all the drivers are updated.  Is there a way to scan multiple pages to one file.  I have tried the three methods mentioned in the HP bulletin for Mavericks but I can only scan one page to one file extension.

    I understand you are looking to do a multiple page scan and save it as one file. I will do my best to help! The full driver for the C310a is not available with Mavericks. In having said that,  you can try using Image Capture to scan multi-page documents.

  • I cannot log onto sites that require my log in and password. I get no error message, fire fox just goes back to the same empty log in screen. this problem is not limited to one site. I reloaded firefox with same results.

    When i type in my log in and password and enter, the site either returns to the blank screens or does nothing. This is not limited to one or two sites. all of my financial institutions, electric company, insurance companies, even trying to register here so that i could ask this questions. In this situation, when i hit the register button, nothing happend, its as iff the button is inactive. i had to go to IE to register and post this question. I just tried to enter my new log in and pw on the screen in fire fox and nothing happens. Some sites behave differently when i hit the submit or log in button. the information seems to be transmitted but the screen comes right back to the original log in screen with blank fields. there are no error instructions that something does not match or is missing. then i go to IE and it works.
    This started a few weeks ago. I cant identify anything that was added around that time but i tried a system restore and that did nothing. i deleted fire fox and downloaded the latest version 3.6.13 and it is still happening
