Looking for design help

Looking for a help of design with this scenario

A user can double-click on a non editable listview and a dialog box will appear. the data entry and display of list is full. When they come out the dialogue, a task is launched to update the database, resulting in the close dialog box and listview parent redrawn.

what I find is that if the user works quickly, they can double-click again and restart the process until the parent listview is redrawn. Everything seems correct, but for several reasons, the update of the database fails.

So, how to disable double click action until the task is completed? The challenge is there several of these boxes of listview and not must be an action until the update of the database is complete and the boxes are redesigned.

Obviously I could loop through each listview box before you open the dialog, remove the doubleclick event handler. so I might have the task to reinstall the doubelclick event handler after the screen new drawing is finished (I can't)?

I was expecting something more graceful...

I was wondering that after I had posted it.

I guess I always think it is advisable to put the update in the background database. It's pretty easy to do, you get all the semantics nice to task.setOnSucceeded (...) and task.setOnFailed (...) that nicely encapsulate the fact that you are waiting for a process to do something, and you would be successfully implemented if you decided to add other features in there. In addition, if you block the thread of FX Application, you will get probably strange results if you cover and then discover your application with another window (your request might not get the opportunity to repaint).

  • Looking for the help of Muse!

    I'm a designer and I love Muse!

    Where I fall down is more tech portions of the program... form feature in menu... I'm looking for a collaborator.

    Currently, I have 95% completed a site in the format of office (always the need to add a Mailchimp subscription form and adjust some menus for features) and would like to see that someone else to complete the mobile and tablet versions.

    It is simply not cost-effective to have me tax my left brain when I can concentrate on my right brain and move things like this back and following someone more adept at Muse... basically, I'm looking for a go - to person for Muse... anyone interested?

    Please send your level of expertise, your pace and a little about what you do... maybe there is a match for us!

    Thank you!

  • HP 6700 Assistant what function the printer option? Looking for a help file.

    I just istalled an Office jet 6700, one of the shortcuts on my desktop is labeled HP Officejet 6700.

    When I click it I get four options, HP Printer Wizard, set preferences, see what's printing and customize your printer.

    Outside the HP printer assistant, they do what they say.

    I click the button Wizard from the printer and nothing happens, but I think I need the Printer Wizard to access the help file.

    My Panel said aid has been loaded, but I can't seem to find it.

    I've uninstalled and reinstalled the device three times now.

    One of the ideas please?

    running windows 7 64 bit printer is on an ethernet connection

    Hi George,.

    Open start > programs > HP > HP Officejet 6700 and follow the Uninstall option.

    Then install the latest version below, be sure not to use the original CD that include older software:

    Now open the HP software and check any change.

  • Looking for answers/help to understand how can I "fix".

    Hola... .new

    I got a nav div with a color, width, and a high properties that are crossed with a line in my CSS Inspector

    If I pass the mouse over it, it shows this

    "background color does not apply to your selection because it is not inherited. It is applied to an attached tag.

    However, the elements of the page are transparent by default, so this color may appear through"

    So, what happened?

    How can I fix it?

    Thank you

    At this point, you are best placed to find out why this happened and how to fix it.

  • Looking for advice for a new user to vmware

    Hi all

    Looking for a help and advice for a rookie to vmware

    We have just purchsed 3 x DL380 G8 each with 8 x 1 TB HARD drive no storage shared, and we are currently approved for most part more packs 2 x.

    What I wanted to do was to reproduce some VM so if one breaks down then we can either manually or automatically start another on another host. I'd like to reproduce our exchange 2010 essentially server but that is currently on the phyiscal material and I would need to first do a P2V conversion. I also read a few negative articles on running exchange on a virtual computer.

    I had read a little and looks like FT is outside the quetsion because of having not shared storage in place and there is also the limitation of 1vcpu. So I was wondering where to start really. For any tips, pointers, etc. will be very much appreciated.

    Thanks in advance for any help.

    Welcome to the communities...

    As you use Essentials Plus, you can order vSphere Storage Appliance you can use a shared storage. Make sure that the hardware is compatiable with vSA (http://blogs.vmware.com/vsphere/2012/12/major-hcl-changes-for-the-vsphere-storage-appliance-vsa.html)

    What I wanted to do was to reproduce some VM so if one breaks down then we can either manually or automatically start another on another host

    vSphere HA done for you if you are eligible.

  • I'm looking for a link to the 'Adobe Creative Suite Design Premium' Netherlands/Dutch version

    I'm looking for a link to the 'Adobe Creative Suite Design Premium' Netherlands/Dutch version. I was promised this week to be contacted by a "senior" by Adobe support person. But after 5 days still nothing. Need help finding the download package. It is not available via the Adobe Web site.

    Who can help me please?

    [Go to the living room to a support forum - Moderator]

    I think it's more creative Cloud as Creative Suite.

    Language switching in Cloud applications is a preference setting. Switching language non-Cloud has always required contacting Adobe, as the license is tied to the language. Language files must be included with the installer and the legacy versions are archived with different groups of language files.

    For the Suites and standalones inside each suite - I have always understood that the languages listed next to each link are the only ones to be included in this specific download.

    Very few languages listed for CS5 Design Premium. No Dutch so I do not think the OP won't get a Dutch version of one of the links below.

    Thanks for your help.

    I can look to iCloud by car and see its contents.

    However I can't iCloud pictures like this to see the content, etc.

    This is the reason why I wanted to disconnect from iCloud. I had hoped to reconnect and see if I could get then in my photo iCloud content!

    Maybe I have the wrong approach?

    can you tell me if the Photos on my iPad and iCloud photos are one and the same?

    any help appreciated...

    They should be the same.

    To display your iCloud on your iPad photo library you're following the steps below?

    Go to iCloud.com using Safari.

    Keep your finger pressed on the semicircular arrow at the end of the URL bar.

    Press "Ask site desktop."

    Connect to your iCloud account.

    Tap the photos icon.

  • Looking for a w/SOUND Gmail Notifier. Using Windows 7, Firefox with igHome. Any help?

    I'm looking for a Gmail alert system with the sound. Just a pop-up window is not enough for my needs. I use Windows 7, Firefox and igHome. Gmail is open, at any time, in a pinned tab. Please note that the notifier must have sound advice. Thanks for any help.

    It does wonders for me
    https://addons.Mozilla.org/en-us/Firefox/addon/Gmail-Notifier-Restartless/?src=userprofile

    Gmail doesn't have to be open in a tab. But Firefox must be run.
    Add on has enough parameters to customize it to your liking.

    Maybe not for you but there is also a nice for Google calendar calendar add-on.

    I have a complaint on my Mac Book Pro. I bought my computer in January 2016 and it has two problems: the first is the display of the retina that has many traces of the keyboard and as many times it freezes. I have looked for help on the local Apple Store and support too, but it did not help. I would like you help me solve this problem.

    Thank you.

    Kelly

    Your machine is still under warranty, so you should take it to your local Apple store for repairs. Function late in January, you bought it, you still have phone without support. If you can't find any help on the Apple Store, then I don't know what you expect to find here. We have no way to check for problems you have described or any additional hardware, etc.

    10.10 is no longer available unless you had previously downloaded. In this case, it would be in the purchase of the Mac App Store section. Its not available for direct plus download.

  • "looking for credential tiles" - unsuccessful removal of Veriface and ReadyComm - HELP :(

    Hello

    I did some research and tried and called and did everything, but can't seem to get my Lenovo to play nice.

    I bought this computer only a month or two before and have placed since my materials of the entire work here so a total rebuild of the system's very unnatractive.

    My main problem is, when I put up Outlook 2010 (expensive full version) with my exchange account that is hosted by Go Daddy (who were very patient with me and all my calls - it was also the expensive full version and all settings have been checked several times so it isn't a fault it), if I config it automatically or manually , the "Windows - Microsoft Outlook security - connection to [name]@[domain].com - looking for credential tiles]" pop box and will not die.

    I have read the forums and I saw that people had success uninstall (or the less disabling) ReadyComm (which was very difficult to find, but I did) and VeriFace I went and made through Control Panel.

    I restarted my computer and VeriFace has obviously not been eliminated, and the message of credential tiles was always there.

    I started my computer in safe mode, fact the msconfig and c:\programdata steps, actually purchased a software that promised to help me remove programs during good behaviour and all nothing is helping.

    I'm at the point now where I just want out of here, all programs from Lenovo (even if I'm afraid of the stuffing something upward) and all the downtime of not being able to use Outlook correctly (and trying to uninstall everything) drives me crazy.

    I actually did call to Geeks2U services, and even they couldn't fix it.

    Why is it so difficult to get around this? How can I make without a comprehensive re - build? Is there anyone out there?

    I do some reading in the tiles credential... my apologies in advance, as I'm not familiar with windows key rings.

    It seems that your research is correct: VeriFace interferes with the authentication system.

    Have you tried to reinstall VeriFace from the site, so that you can do a complete uninstall of it? If this does not work, could you post the errors that occur in your event viewer? There could be an indication as to where the authentication will fail.
