What is the right time to call the pushScreen()?

Hello

I made a screen that simply indicates "Loading"... "while my app works through its processes. the problem is that the screen never had pushed until after the function when pushScreen() is back. the call looks like this:

function func() {

//I'm hoping the loading screen would be pushed right here....

app.pushScreen(loadingScreen);

//app does its stuff

return;

//but instead the screen is pushed after func() finishes.

}

what I am doing wrong?

Thank you

Edit: I forgot to mention that this function if calling from a menu item, and in fact the menu itself doesn't close until after func() is done. How can I fix it?

Or, a bit simpler:

new Thread() {
    public void run() {
        // do the work here
    }
}.start();

Somewhere in run(), once the work is done, you can call Application.invokeLater (), passing an executable to update the UI with the results. (Alternatively, you can update the user interface of a separate thread by synchronizing on the object returned by Application.getEventLock (), but that is more complicated).

  • What is the best event each time the called component

    I have an application with multiple forms in separate components. I want to fill in this form with the data when it is load based on a datagrid selection. I have the function of the population attached to the event createComplete of the component. But that only triggers when I first call the form element. Next time when I call, the form does not trigger the function such that she has already created previously. Can someone let me know what is the event that I need to call my form fill function?

    If your condition is not very clear, you can use the component updateComplete event. It is distributed whenever a component is updated.

  • What is the "right way" to archive watched as TV shows to save space on my SSD in iTunes 12.3.3.17?

    I 212,92 GB in my iTunes Media folder on my Mac Book Pro with 751,28 GB SSD and I need some SSD back space.  I saved the file whole iTunes on an external drive, and I use a time Machine TB 3.  What is the 'best' way to remove TV shows I have watched but you may want to look again to retrieve the piece on my SSD?  Is it somehow within iTunes to do this, it can easily reload archived videos?  (For example like the original tΘlΘcharger the cloud when I bought it, but now my own sauvegardΘ?) p.s. Sorry, but none of the categories seem right for this issue. LRC

    A few options, I can think. One is to simply copy the media itself on the external drive and remove the entry from the library in iTunes. When you want to use it then "add you" the external file to iTunes that will put a copy on your computer that can be removed again after having watched.

    Another option is to create a separate library for items stored on your disk to archive.  Create a new library by holding down the option key while starting iTunes and tell him to put on the external drive you use for videos.  Drag the items currently there in the folder automatically add to iTunes in the Media folder on the outside.  Toggle the use of the library back if necessary.

    You need to maybe turn off or change automatic downloads so that they are not constantly re-uploaded in your main library.

  • Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?

    Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?

    I'm going to assume that you plan to have wireless devices.

    Let's say that the Capsule is your "main" router  If this is the case, then it must be located in the House, so that the distance between the time Capsule is the same for the outside walls of the House.

    Then, on the 'left' side of the House, looking for an airport to midway between the Capsule and time of the outer wall of the House. Do the same thing the 'right' side of the House.

    In other words, each of the two airports that "extend" the wireless signal are located at equal distance from the Capsule of time... but they are in opposite ends of the House.

    If you intend to interconnect all the airports and Time Capsule using a permanent, Ethernet wired... which by far is the 'best' way to put in place a network in terms of performance and reliability... then you can locate one of the devices anywhere you want.

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

  • What is the best option to get Email group subscription to CRM Contacts (in time real/as it changes)

    Hello world

    I evaluate me and come up with approaches multiples, but want to ask everybody, what is the best and easiest method to get subscriptions to e-mail to CRM Group since they change, virtually in real time in CRM (SFDC or other).

    I understand internal call/event allows only the global subscription status be synchronized with CRM, my problem is subscription group.

    Would love to hear all of the approaches.

    Thank you

    Amit Pandya

    Hi Amit,

    Others may have another alternative, but what I've done in the past is to create a "Subscriptions" Eloqua field both SFDC and make a multiple selection with the same values as the E-mail groups in Eloqua. Then, when a person subscribes to some groups of Email, in addition to the update of their Email Group subscriptions, I also update the values in the field 'Subscriptions' and then add in the update CRM program so that subscriptions are updated in the master record or Contact SFDC.

    I work with a client who succeeded subscriptions on the side SFDC in an object custom. It's doable as well, but it is a bit tricky when people of the Nations United-subscription of a group. We ended up creating a record for every email of the contact group to subscribe on a custom object with the name of Group of e-mail and a value of 'Yes' in a field called "Customer", and then if the contact came back and unsubscribed from a group they have already subscribed to, we updated account of this group of e-mail on the custom with a value of 'No' object in the field 'Subscriber '. A little more complicated and more difficult to manage and maintain, but it allows more coverage as you can tell for each group of Email when someone is first of all a (rather than having a single field of "Subscriptions" in the main folder or Contact which houses all subscriptions).

    Hope that helps!

  • Adding more than one host ESX and the upgrade at the same time.  What is the order of preference of the operations here?

    We are budgeting for more licenses and hardware for 2014 and want to do immediately in January.  I am trying to decide what is the best order of operations for adding two vmware hosts additional to our current installation of vsphere and also upgrade our vsphere / esx 4.1 u3 for the latest and best.

    We have 3 Dell PowerEdge R710 running ESX 4.1 U3.  In this vmware cluster, there is a vcenter server 4.1 U3 virtual machine handle this.  The three servers are about 90% memory used so we add 2 additional servers.  Probably the Dell PowerEdge r.620 since we get up 2 in the space of a 710.  Storage is on a san EMC NX4 NFS which will become too but not yet, let's just deal with the vmware part.

    When adding additional r.620 2, should I install ESX 4.1 on them and join them to the existing cluster and THEN pass vcenter and each one esx?  I ask precisely because 90% of use on 3 current servers, I need 2 other servers to support the update operations take place.  They would be able to repel vmotioned vm while each host receives an upgrade at the same time.

    So which is the best way to go about adding of the hosts and the upgrade?  Would I add as 4.1, then they would be available as targets vmotion and so I have room to start the hosts one upgrade at a time?

    If I update vcenter to the latest version, it is comparable backwards and can manage the 4.1 hosts, but also hosts 5.x?  I guess version 5.5 is the last one I would get from VMWare?  It is right of ESXi, then, how is this ESX ESXi 5.5 4.1 upgrade?  How much storage space do I need for ESXi 5.5, as I'm dechatoiement out of these r.620 Dell and need to know what hard drive to put in.

    The steps that you must follow

    -Updated vCenter Server

    -Upgrade of the ESX hosts (because we do a updating of the material we will install 5.5 on our new guests and add them to the cluster and then dismantle our existing)

    -Upgrade VMWare tools

    -Update data warehouses

    ESXi 5.5 has these storage requirements:

    • Installing ESXi 5.5 requires a boot device is at least 1 GB in size. When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device. If a smaller drive or logical unit number is used, the installation program attempts to allocate a region scratching on a separate local disk. If a local drive is not found, the scratch partition (/ scratch) is located on the disk virtual ESXi host, linked to the/tmp/scratch. You can reconfigure /scratch to use another drive or logical unit number. For best performance and memory optimization, VMware recommends that you leave no /scratch on the ESXi host ramdisk.
    • To reconfigure / scratch, see Configure the Scratch Partition of vSphere Client vSphere Installation and Installation Guide.
    • Because of the sensitivity of the I/O devices, USB and SD, the installation program does not create a partition scratch on these devices. Therefore, there is no tangible benefits to the use of the great features of USB/SD that ESXi uses only the first 1 GB. When installing on USB or SD, tent Setup devices to allocate a region scratching on a local disk or the data store. If no disk is local or data store, /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
    • In Auto deploy facilities, Setup attempts to allocate a region scratching on a local disk or the data store. If no local disk or data store is found /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
    • For environments that start from a San or use Auto Deploy, it is not necessary to assign a separate logical unit number for each ESXi host. You can co-locate areas scrape for several hosts ESXi on a single LUN. The number of hosts assigned to a single LUN must balance the size of the LUN and behavior I/O virtual machines.

  • Is this the right time for an improvement of the system?

    Having finally started using the installation of first Pro CS5 that has mainly been used for the better part of the year, I find that my three year old system is need of an upgrade.  It works well enough for the edition, but takes an age to make anything.

    The current system of NY is:

    Q9550

    8 GB DDR2

    2 GB HD4850 (I had with my previous card nVidea drivers problems)

    300 Gb 10 k rpm WD Velociraptor (OS and program files)

    150 GB 7 k 4 RPM Velociraptor (stripes only)

    2 x WD black 1 TB internal

    2 x WD 1 TB external USB3 (I like these.)  They are about as fast as my internal drives)

    Gigabyte power 650W

    Windows 7 Home Premium 64 bit (OEM version) that replaced Win XP 32 bit with only 4 GB of DDR2 and made a lot of difference with Photoshop.

    I think similar to

    I7 2600 K

    Gigabyte Z68XP-UD3-iSSD (with the 20 GB SSD on the map)

    GTX470

    24 GB of DDR3 memory

    Windows Professional (to access the 24 GB of RAM)

    I hope to keep my current box and the PSU.

    Issues related to the:

    (1) would it be a good idea to get a second 300 Gb 10 k rpm Velociraptor and Raid 0 them?   I think it would give me useful capacity and speed for the C: drive, and I wouldn't have to wait for my data drives to wake up.

    (2) the person performing the upgrade tells me that he has much spent with this time - especially with AMD processors.  Intel only resemble revise the i7 to a 2700K with an another 100 Hz which looks stupid with the 2600 k being so easy to OC.  Is it worth of waiting?  I know that advises the usual for this kind of question is there is always something to come along, then get on and enjoy what's available now.

    Thank you very much

    Of course, now is not the right time to upgrade, with the new Intel processors and appropriate motherboards that will be released next month?  I know that he will remove the 4 sticks of memory - limit I've seen pictures of motherboards with 8 memory slots.  Will be also lifted the restriction on the PCI express lanes.  As they must be passionate oriented, there are 6 core processors, and I hope there will be Asus cards without the integrated Intel graphics card.  Rumor has it that would however be much gain in speed.

    I'm in the same position as the OP - a system of 3 years, but with a slightly more powerful processor.  Dear as I would have liked to pass earlier this year, I have steeled myself to wait until February when I return from my winter migration.  Here, problems of teeth with the new processors and motherboards must be known.
