[JFileChooser] How to get the local network servers list?

Hi, i try to use a JFileChooser (and its FIleSystemView) to retreive the list of local network computer.
In the UI, i can see it but i don't manage to get that list outside of the jfilechooser.
When I do : new File(\\\\Server\\Directory).list() I have a good answer.
But hen I do new File(\\\\).list() to have the server list, i have nothing. I don't manage to list the workgroup too.
Thanks a lot.

  • I'd like to know how to get the SIM Network Unlock PIN for my DROID2 GLOBAL

    I am living in Haiti and I made someone buy a Droid2 Global for me in USA. I have had the phone for 2 months but I never could operate it.  Any time I open it, it requires that I enter a SIM Network Unlock PIN that I have not.
    I' d appreciate you help me get the SIM Network Unlock PIN for my Droid2 Global which IMEI is the following: {edited for privacy}.
    Many thanks in advance

    If the incorrect PIN code is entered too many times, a PIN Unlock Key must be obtained from Verizon Wireless at 908-559-4899 if you are outside of the United States and 800-922-0204 or *611(send) from your mobile number inside the United States..
    The SIM PIN option is only available when the handset is in GSM / UMTS mode. Refer to Network Mode Setting for further assistance.
    Thank you, LatachaM_VZW
    Are you talking about the PUK code (when the PIN for the SIM has been wrong too many times)?  The OP is talking about network unlock, and is using a foreign SIM.   Global Services certainly wouldn't have the unlock code for a SIM that isn't theirs.
    I have heard that if you do enter the incorrect network unlock code too many times, the phone becomes permanently locked (i..e cannot be unlocked even with a valid unlock code) but not everyone agrees that this is true for all phones.
    Jax's post above really says it all, you will need to search the web for a service that will unlock this Motorola phone.  In doing so, you might find a number of threads that say the Global has to be activated in the US before an unlock code will work.  Others were able to unlock without this. 

  • How to get the local file system path of an image that loaded into the image component in cq5?

    Hi,
    I'm having hard time uploading image from filesystem where as drag and drop works.
    I'm not getting a path of image selected from filesystem.
    here is my code..
    private String populateImage() throws Exception {
                        if (currentNode != null && currentNode.isNode()) {
                                       Node ImageNode = JcrResourceUtil.createPath(currentNode, "image",
                                                                          null, "nt:unstructured", true);
                                       imageUrl = ImageNode.hasProperty("fileReference") ? ImageNode.getProperty("fileReference").getValue().getString() : "";
           imageUrl = imageUrl.trim();
            log.info("MANAGE PROFILE BEAN IMAGE URL INSIDE IF IS: " + imageUrl);
                        } else {
                                            imageUrl = properties.get("fileReference", "");
                                            imageUrl = imageUrl.trim();
                                            log.info("MANAGE PROFILE BEAN IMAGE URL INSIDE ELSE IS: " + imageUrl);
                        return imageUrl;
    So if I drag and drop..
    ImageNode.hasProperty("fileReference") is returning a valid path
    but if I upload an image  it is returning Null.
    So how to get the path? any suggestions around would be appreciated...

    When you say path you mean you want the path to print out in your HTML? Is that accurate? If so you generally need to constructe that path based on the path to the current component. So if you component is located at /content/mysite/en/about/mypage/jcr:content/parsys/image then the path to the image would generally be something like /content/mysite/en/about/mypage/jcr:content/parsys/image.img.jpg/1283829292873.jpg. The .img. selector triggers the servlet associated with the foundation parbase - /libs/foundation/components/parbase/img.GET.java. The reason you reference it this way is that there is no filesystem path to the image - it is stored in the repository not on the file system, and it requires a servlet or script to ge the binary from the repository and steam it.
    Normally the way you'd construct this is to use the out of the box Image class - so look at /libs/foundation/components/image/image.jsp. Now this example assumes that your component where you loaded the image extends /libs/foundation/components/parbase. If it doesn't then you either have to change your sling:superResourceType to /libs/foundation/components/parbase or some other component that does exten /libs/foundation/components/parbase.

  • How to get the local IP address?

    Hi,
    I try to obtain the users local IP address similar to:
    InetAddress localHost= InetAddress.getLocalHost();
    String localIP = localHost.getHostAddress();
    InetAddress[] inetAddress = InetAddress.getAllByName(localHost.getHostName());
    for (int k = 0; k < inetAddress.length; k++)
       if(!inetAddress [k].getHostAddress().equals(localIP))
          return inetAddress [k].getHostAddress();
    }This code works fine in a stand alone application. When I try to use it in conjunction with Web Start it only returns 127.0.0.1.
    I think there's no Service from Web Start that gives me the users IP address. Or am I wrong?
    Does anyone know a solution for this?
    Thanks in advance!

    Hello,
    I use java.net.InetAddress.getLocalHost().getHostName();
    in my javaws and I get the real hostname.
    Probably your DNS is not correct,
    or other possible problem: sign your jars, so you get full access to the System resources.

  • How to get the locale/region of the device?

    I want to retrieve the locale/region being used on the user's mobile device (doing this on iOS at the moment) and seem to be having difficulty figuring this out.
    I need to be able to distinguish between en_US, en_UK, en_CA etc.
    Capabilities.language & Capabilities.languages just seem to return the language "en" and not the locale/region being used for the device.
    I've also tried using
    var defaultLocale:LocaleID = new LocaleID(LocalID.DEFAULT);
    trace(defaultlLocale.getLanguage + "_" + defaultLocale.getRegion());
    But this just results in an output of "i-default_" (invalid language setting and empty region setting).
    Any ideas on what API calls I need to be using, or what I'm doing wrong?
    Thanks in advance

    Well it looks like if you go into the devices Settings->General->International->Language you can set the preferred language to "British English".
    This will then cause Capabilities.languages to return "en-GB" for the first element of the array (the prefferred language). Not sure why it doesn't use proper locale/region codes, but that's another discussion.
    The remaining issue is that there is no device setting for "Canadian English", so this doesn't completely solve my problem.
    iOS devices do also let you set the "Region Format" which does have a "Canada" setting. I'm guessing that I could use this as a work around if we have access to the "Region Format" data through some AIR API. Does anyone know if we have access to the "Region Format" information on iOS devices and how we'd access that information?
    Thanks.

  • ECC6.0 t-code COOIS - how to get the "Profile" select-option list

    Hi  PP Gurus
    We are implementing ECC6.0
    We upgraded one of the systems from 4.7 to ECC6.0 (and also kept data: documents, users profiles, variants,u2026etc).
    My question is regarding standard transaction COOIS.
    I do comparison in current 4.7 and ECC6.0 systems (I have SAP_ALL and SAP_NEW in both systems).
    The thing is that in our ECC6.0 system the transaction COOIS doesnu2019t display Profile on select-options screen.
    There are only the following items (select-option screen of COOIS in ECC6.0):
    -LIST
    -LAYOUT
    -Prod.orders checkbox
    -Planned orders checkbox
    u2026And u2018Selectionu2019 tab with other fields
    In the current Enterprise 4.7 system the transaction COOIS displays the following select-option screen:
    -LIST
    -PROFILE
    -LAYOUT
    -Prod.orders checkbox
    -Planned orders checkbox
    u2026And u2018Selectionu2019 tab with other fields
    Questions:
    1.     Is that possible to maintain / see and select a PROFILE in COOIS of ECC6 (or due to new functionality it no more available on that screen ?) How to do that?
    2.     Looking at layouts (I ran COOIS in two systems and compared the results) I canu2019s see in ECC6.0 some icons like u2018Refreshu2019, u2018Order logu2019, u2018Display order componentsu2019, u2018Long textu2019 , u2026.) But all of them are in 4.7 layout. How to get them in ECC6.0 ?
    What I have already explored:
    u2022     ECC6.0 has a new config. t-code COISN (4.7 has only COIS) . I created my new overall profile there, set my own layout, but running COOIS still canu2019t see/use the PROFILE;
    u2022     I have compared the standard structure PPIO_ENTRY_SC1100 in 4.7 and ECC6.0 and found the new component COIS_LISTTYP in ECC6.0. In this situation I ran a new t-code u201CDefine New List Typesu201D (it doesnu2019t exist in 4.7) and created my new entry, but still canu2019t see PROFILE on select-option screen of COOIS in ECC6.0;
    u2022     I also tried situation when both config. transaction COIS (in 4.7 and ECC6.0) had the SAME overall profiles u2013 still canu2019t see PROFILE on select-option screen of COOIS in ECC6.0;
    u2022     I found a new icon u201CNavigation profileu201D in result layout of COOIS ECC6.0 Is that right place where I can maintain the icons I need (see my second question) ?
    THANK YOU.

    Hi,
    The reports are modified if am right as of ECC 5.0. Refer to note - 747469 which gives a list of all reports modified.
    If am right by profile you mean navigation profile, this is now in the display screen. The content remains, only thing is the layout is modified & more structured. So i would suggest you to have a look around in COOIS report & you will find the info.
    The navigation profile is adjacent to the icon called Environment (its a drop down list).
    Revert if you face any issues.
    Regards,
    Vivek

  • How to get the local date time value

    Hi,
    I am Australian time zone. I have been using the below code to retrieve meeting start date time from my Sharepoint Calendar.
    Console.WriteLine((DateTime)oListItem["EndDate"]);
    This used to return the correct local date up until today. I simply read this and store in a database. Today when I check I can see that the date returned is different to what I can see in the Sharepoint calendar.
    For and example: In Sharepoint calendar I can see the date as "Oct 1 2014 5:30 PM". But my above code now returns "Oct 1 2014 6:30 AM". This looks to me like UTC time.
    But up until today my code above returned the correct local date. Is there any reason for this sudden chahge?
    When I read the TimeZone in sharepoint (using RegionalSettings.TimeZone method) it return the correct time zone too.
    Any help would be appreciated. I am concerned that I have to now go and change all places where I read the date time from sharepoint.
    Thanks, Bimal

    Hi,
    According to your post, my understanding is that you had some issue about the calendar time.
    As your code worked well before, the issue may be related to the calendar itself or the site.
    As the TimeZone is correct, you can recreate a new calendar to check whether it works.
    Or create a new site to check whether it works.
    I had made a simple demo to retrieve the calendar EndDate time, you can also check with it.
    using (SPSite site = new SPSite("http://YourSiteURL "))
    using (SPWeb web = site.OpenWeb())
    SPList spList = web.Lists.TryGetList("Calendar1");
    if (spList != null)
    SPQuery qry = new SPQuery();
    qry.ViewFields = @"<FieldRef Name='EventDate' /><FieldRef Name='EndDate' />";
    SPListItemCollection listItems = spList.GetItems(qry);
    foreach (SPListItem item in listItems)
    string startTime = item["EventDate"].ToString();
    string endTime = item["EndDate"].ToString();
    Console.WriteLine("Start Time:"+startTime);
    Console.WriteLine("End Time:"+endTime);

  • Getting the local full path name of a file from an item File Browser

    Hi all,
    I would like to get the local full path name, of a file selected from an item 'File browser'.
    I see in wwv_flow_files the column 'name', but actually it's a kind of id like 'F1542335/myFile.gif' for example.
    What i want is the local path of this file ("C:\Documents and Settings\All Users\....\myFile.gif").
    I hope this is possible??
    Anyway, thanks all for reading.
    Ludo

    Hello, thank you for the answer.
    Please understand that I searched before posting, and not ony 15 min.
    What i mean is that the value of a File Browser in an Apex applocation is something like 'F1542335/myFile.gif', but what I need is the local path location.
    And 'F1542335/' is not the local path location, i can't use it. Or maybe there is a way to convert it in a proper path name, such as "C:\Documents and Settings\....", but I don't think so.
    So my question is : how to get the local path name of a file in Apex?
    I'll answer if I find some good things.
    Thanks

  • How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

    How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

    If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
    That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
    This page is a good starting point for learning about Flex and PHP communication:
    http://www.adobe.com/devnet/flex/flex_php.html
    Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/
