Can event listeners be listened to by components which they are registed on

Is it possible to have an event listener being listened to by the component on which it has registered interest to listen for changes. I am linking a database to a GUI and i have indicated that the GUI listens for changes to the database, but can the database also listen for changes to the GUI without having to make the database register interest in listening to changes to the GUI.

The changes you wish to dected within the GUI must be listened to. Not neccesarily by the database. Changes to the database can be made by the listener that is registered on the GUI. What GUI changes are you trying to respond to?

    Hi..
    Thanks for the reply..
    My original I Phone 5 was running IOS 6.12
    My I phone 5S currently runs IOS 8..When I upgraded it, it had IOS 7 on it which made the I Photo app compatible with everything below IOS 8...( which the photo app is not compatible with ) so I just connected the I Phone 5S to my computer and thinking the new phone had IOS 7 on it that these was nothing to worry about..I thought all 900 + pictures in the photo stream would transfer but somewhere in the process, I Tunes decides to just go and install IOS 8 which requires that you run a " Photo Migration App" to transfer photos from IOS 7 & below. The problem was is that I didn't want IOS 8 on my new 5S so I thought I wouldn't have to do that part..
    Anyway the phone emerged with IOS 8 on it and the only photos that remained were the ones that were actually on the phone..The 900 + I had in the stream didn't transfer because the Photos that works on IOS 7 and below isn't compatible with IOS 8..I guess you have to use the photo migration app that comes with IOS 8 & I phone 6..But I didn't ask to upgrade to IOS 8...It just did it on it's own!
    I still have the I Phone 5 Back up that I did just before giving it back to Verizon but if I try to restore the I Phone 5S running IOS 8 those photos in the stream will not go back on the phone because IOS 8 isn't compatible with the I Photos" that ran on IOS 7 and below..
    So I have an I Pad mini that runs IOS 7..should I try and erase it...and put that I Phone 5 backup on it and pray the photos that were in the stream come back on it so I can transfer them back to my computer...then erase the I pad mini again and restore it using it's original backup that I have on the computer and the in the cloud?
    I know this sounds confusing but I'm at a loss as to what to do..This is what I found ...http://support.apple.com/en-us/HT201386
    but it doesn't help me..

    Major Update: The G-Keys can now be edited without recompiling by editing shell scripts at "/usr/share/g15daemon/macros/"
    Each button has it's own script file named by it's label (e.g. to edit the functionality of G1, open the script named G1.) The button will try to execute the scripts as programs, so make sure they are executable (chmod +x) and as long as the name remains the same, if you want to replace the files with something different, know that the arguments currently given to the files ($1 and $2) are ($1)on/off and ($2)0-2  (where 0 is M1 and 2 is M3)
    To download the updated sources, go here (only the g15daemon source/patch was updated). This thread's OP has been updated.

  • I got a Mac Book Pro from my company, and I can't update the apps because they are registered to another Apple ID.  Is there a way to change this so I can update my Apps?

    As it says, I got a Mac Book Pro from my company and I would like to update the apps on it.  They are registered to a former employee's Apple ID, is there anyway for me to change it to my Apple ID?  Or do all of the Apps need to be re-purchased?

    Welcome to the Apple Support Communities
    You must repurchase the applications because you can't transfer programs from an Apple ID to another one

    Did some searches, but did not come up with anything regarding your specific issue (the original one, the grey 'waiting' problem is quite common). If no other ofrum users chime in, it is indeed time to contact Apple / iTunes Store support.
    If you have not yet one so, Try to Reset your device.  Press and hold both the Sleep/Wake button and the Home button for at least ten seconds, until the Apple logo appears (ignore the Slide to Power Off that shows up first).
    You could also try to re-download one or two apps, just to see if anything changes. Log in to the iTunes Store, go to the Purchases section and download from the list of past purchases or free apps.
    Sorry I wasn't of better help. Good luck.

  • How to kill TCP-IP Listen or Open Connection while they are waiting to connect?

    We have an application that acts as a control panel for a customer's device.
    It connects to the device using TCP-IP.
    It can be configured to connect as a server (listener) or as a client.
    The user of this applicaiton must have the ability to disconnect from the device and point and connect to a different device at a different IP and port.
    When the user tries to connect to a device but can not (the device is not ready or the IP address is wrong) he wants to abort the connection, change the settings then restart the attempt to connect.  
    How do I stop the TCP-IP Listen or TCP-IP Open Connection VIs?  We typically use a timeout of a couple seconds and this is a long delay for a respond to the operator when he wants to abort the connection attempt.

    Thanks for the quick response. 
    I was hoping there was a more elegant Labview solution that may work for both the wait on listen and the connect VI.
    I tried to close the wait on listener by closing the ref from the create listener.
    That works.  See attached picture. I use a queue to send the abort message.  The wait on listen state will be blocked until either a connection is made or an abort message is sent via the queue.  If a message is sent, the dequeue vi unblocks and causes the listener reference to close which will kill the wait on listen VI.  If a TCP-IP connection is made it will close the queue reference which will kill the dequeue vi.
    I guess for the TCP-IP connect VI I can:
    A. Use a couple second time out that is tolerable to the operator if then abort the connection attempt. (like you suggested)
    or
    B. Create a VI with the TCP-IP Open Connection VI in it.  I can launch that VI dynamically and wait until done (invoke node Run VI with Wait Until Done set to true).  If a connection is made it will finish and I will read the outputs using an invoke node (Ctrl Val.Get).  If it needs to be aborted, I will abort the VI using an invoke node (VI Abort).

  • Macbook pro fails to read sd card with movies recorded on it, any ideas? I can view them in the video camera so know they are there somewhere. I am now thinking I should have formatted or initialised the new card before using it.

    My macbook pro is failing to read a new sd card with movies recorded on it. Any ideas please? A previously used SD card has downloaded without problems. I have tried using a card reader as well as downloading from the video camera itself, neither works.
    I can view the latest recordings on the video camera so know they are there somewhere. I am now thinking I should have formatted or initialised the new card before using it but didn't think of that at the time. Obviously don't want to do this now as it will wipe the movies.

  • How can I restore my playlist folders in itunes? They are there but the individual song titles aren't listed. They are only listed by album. This makes it very difficult to find songs in my playlist.  Also,when I click on music, it will not list options.

    My itunes account is messed up. How can I restore my playlist folders in itunes? The list's are there but the individual song titles aren't. They are only listed by album. I can only see the song titles as they are played at the top of my itunes. This makes it very difficult to find songs in my playlist.  Also when in the itunes store, I am not able to see music genre choices, or search for a song or group.
    Thank you

    Hi dones49,
    It sounds like your issue here is that iTunes can not find the files for some of the songs you have brought into it. This happens occasionally even if the songs have not been moved from the location that iTunes places them on import or purchase. When you try to use the song, iTunes prompts you to find the file, as you have seen.
    To find the file, use the information in this article to navigate through the iTunes media folders -
    Locate and organize your iTunes files
    If you are still unable to locate the files, you may need to download them from the iTunes store again, or rip them from your CDs. See this article for assistance with downloading your past purchases -
    Download past purchases
    Thanks for using Apple Support Communities.
    Best,

  • Can't upload "put" files to remote server unless they are in a folder. Please help.

    I have done many searches on this and found no solutions. Here is the problem:
    When I upload a file from my local site to the remote server it works fine as long as that file is contained in a folder.
    Example:
    I can upload an image from my images folder, or a template page from my template folder with no problem.
    BUT, I can not upload any web/html pages, my CSS page, site map, or any file for that matter that is simply in the root directory but not in it's own folder.
    When I try to do that I get this error:
    index.html - error occurred - An FTP error occurred - cannot put index.html.  Access denied.  The file may not exist, or there could be a permission problem.   Make sure you have proper authorization on the server and the server is properly configured.
    File activity incomplete. 1 file(s) or folder(s) were not completed.
    Files with errors: 1
    index.html
    So every time I make a change to my index page I can't upload it to the server without getting that error unless I use a 2nd party program like Filezilla - which works fine. It is only Dreamweaver doing this.
    I have been using dreamweaver for a long time and had no problems with this site. This all started happening out of no where. and it is happening on my work and home computer.
    I made no changes to my server preferances or anythijng like that.
    I was just doing my thing - being happy - and then BAM, not happy any more....

    Hi there. First off thank you for your interest and your help.
    I have done what you suggest probably 30 times as I have obsessed over this crazy problem for a couple straight weeks before I finaly gave up on CS5.5
    I'm not sure what you mean by REMOTE server. The only server settings I am aware of are the ones in Dreamweaver. Here they are:
    5.0 Settings:
    Server Name = the same values on each
    Connect Using = FTP
    FTP Address = same numeric value on 5.0 & 5.5 port 21
    User name = same on both
    Password = same on both
    Root directory = is blank (I have tried it using / with no luck as well)
    web URL = http://ftp.westbrookadvertising.com/www/htdocs/
    Passive FTP is checked & Use FTP Peformance optimization is checked.
    5.5 Settings:

  • HT4221 I arranged my photos in order on my PC and when I synced them to my ipad they appeared in a completely different order. How can I get my folders to transfer exactly how they are on my PC?

    I arranged my photos in order and in folders on my PC. When I synced them to my IPad they were in the correct folders but completely out of order. How can I get them to sync in the order they appear on my PC?.

    On iOS 5 (if viewing individual photo albums on the iPad) the photo sorting order should be by filename, on iOS 4 it's date taken (from here) :
    iOS 4 sorts photos by the Date Taken tag of the photos. Specifically, your device uses the pictures' EXIF tags to determine the Date Taken information. Your device will look for the following EXIF tags within your pictures:
    Capture Date
    Date Time Digitized
    Date Time Original
    Last Modified
    So you will need to change their names or their dates
