When should I use UiApplication popScreen()

I was wondering where I should use popScreen (Screen screen)?

My request is a bit like an iPhone app that has links in a ListField. When the user clicks on the back of a screen (form B) resume screen has, it is just as likely that screen B are not again.  If I break the screen, that means that if the user tries to go to the screen B, then the application will reload the contents of the network.

If pop is indicated to be used then where can I detect the user pressing the back or previous menu item?

From what I've seen, by pressing the back button makes popping on the screen the default stack. However, if the screen is a global object or static object he popping the stack does not destroy it, and if you push the same object screen, its State will remain as when he jumped. To get a new screen, you will need to make sure you create a new object.

  • When should I use the IRIS PRO that came with my 8600 instead of the built-in OCR scan-to-text?

    I just bought the Premium Pro 8600.  I installed the HP software, that gives me an OCR option for scanning.  I also installed the second disc, IRIS PRO, which is OCR, too.  When should I use each?

    I would use the software OCR supplied with the printer during the formatting of the document to be scanned is simple and use the IRIS PRO when the formatting is more complex.  You should expect some distortion of the two programs well formatted.  Hope that helps.

  • When should I use the 23.98 timeline?

    First of all, sorry for the rather ignorant question. But now. I noticed that quite a few tutorials use a 23.98 timeline. I shoot in 1080 p with the new Panasonic AG-DV200. What is the advantage of a 23.98 timeline and if I where to use this timeline, what should I get in? And then, what would the parameters should I export in if final distribution is for the web? Currently I have film in 1080 p, change in 1080 p, and then export in 720 p. Although I found a model in FCP for export Vimeo and who really look great. Bottom line... I am very confused. Is there a simple guide that I can speak on what to shoot in, change into, then export? As I said, I apologize for my confusion. I should know this stuff now.

    Thank you very much.

    Everyone was new to this thing of frame rate at a given time, welcome to the family.

    Frame rate is a creative decision and a technical necessity. It can also be a ridiculous assignment. If you know that you are releasing a project than a film House, turn in 23.98. But less frames per second indicates your shutter can be opened a little longer for some sweet butter blurry but this is not always desirable and a few cameras will use a conversion process to bake to look like 24 of 30 frames per second. You know your equipment. More images gives you the opportunity to throw some away, farther in the post. Or say that you know that your car breaks down and explosions will require ultra slow so you shoot at 60, 120 or 10,000 frames per second (with specialized equipment).

    But there are tons of other creative and technical factors and the buffs will be in line with the suggestions for you. Try a simple search of "when shooting 23.98?" and you will find links to dozens of sites explainer and forums.

    We never pull at 23.98, but we, for effect, added a filter of conversion of frame projection film for a group of people watching a film projected on a screen. Our corporate stuff is always distributed online and it is (almost) always 30 fps (or is it 29.97) but sometimes 60 (or is it 59.94?).

  • When should I use Paint on Photoshop?

    Most recent IM for Photoshop so it's easier for me to throw my images in Paint to resize and crop.

    I was curious, if other members of the community never use Microsoft Paint for tasks and if so what?

    In addition, should I do this or would it benefit me to use Photoshop for resizing and cropping of images?  I intend using Photoshop, but I rarely have it open since I mostly use development within the CS5 programs and there are orders of magnitude more time to open Photoshop painting.  But even with a Fireworks image and running attended Fireworks I still through my image in paint because it seems faster.  Am I stupid? Should I give up painting? Some shortcut keys for this task would be probably better ahhhh... any idea?

    Thank you

    I don't think I've used MS Paint, since on Windows 2.0. I didn't even know it was still there.

    I just use PS for everything, except JPEG, with butt header information, the PS does not open. Then I just use ThumbsPlus, or IrfanView, open, and then save it with the appropriate header information.

    I did all the data on the algorithms of scaling (resizing) in the paint, but would think that PS would be better. They offer a good range of choice, but perhaps only a similar painting? Even when cropping. What part of these operations do you find easier in the paint?

    If I use PS a lot and have for a long time, image editing software is just a tool in a process. Using the appropriate tool, or that the artist is no longer at ease, is the trick. I use the (now Corel) painter for a large number of treatments, but almost always end up in PS. Over the decades, PS became closest to painter, as in days past. Yet, there are treatments that I want to apply to the painter, and some of those choices will be my personal comfort level. I have something very similar to my most recent PS, but if I know that each step by heart in painter, my comfort level increases.

    Use what you like for different operations, but I have a Visual control with surgery, as the scale/resize. Do the same exact operation of each program, using the same base Image and the same exact settings. Compare the results of two critical programs.

    Good luck

  • ADDED_TO_STAGE, when should I use it?

    Hello.

    I´d like to know in which cases it is better or not to use the ADDED_TO_STAGE event.

    Thank you

    Not always necessary, of course, but if your movie is loaded by another movie and you try and stage of reference in the constructor, that it won't work - that the constructor runs until your file is completely loaded. In this case, you can use added_to_stage.

  • What is the function local folders are used in TB? When should I use/non use?

    What is the 'local folders' function does TB? How is it related to the 'archives '. 2015 archives disappear after 2015 or 2016 pop up? Why not just add subfolders Archives rather than 2015 Archives? Documentation on these topics?

    Archives and local folders are not related. You can create an Archive folder under "Local folders" account however.

    I use Windows 7 with firefox as my default browser. When I download a program using firefox, I wonder if I want to save the file, and then must go to the download folder to start the download. When I download using internet explorer, I gives me the ability to run the download at the time where it is downloaded instead of save the download. Is there a setting I can change to allow me to run downloads when using firefox instead of record?

  • When should I be connected to iCloud on my iPhone

    When should I be connected to iCloud on my iPhone

    All the time. in my opinion there is no need to disconnect. But that's just me. iCloud works in the background. synchronizes photos, bookmarks, passwords, etc. All data, which must be recovered, when for example you lose your phone.

    Do not turn off during the night, do not turn on flight mode use the mode night so, iCloud can do a full backup. The phone must be powered and needs active WiFi.

    Turning off iCloud will take you to the time of Nokia 3310.

  • Should I use Windows update for updates or download Toshiba bullet only?

    Hello

    I have Toshiba Satellite laptop computer with Windows XP. I wonder what should I use windows update to download patches and additions or only
    install quick fix from the Toshiba support pages? Is there a difference?

    I noticed that to the Toshiba support site, there is no new update (miracles) have come in this year at all.

    I ask this because I have some time ago asked Toshiba (when I contacted their support) I use only WLAN updates provided by Toshiba, Intel does not update even if I have the Intel WLAN card in my laptop and there was new driver at the side of Intel.

    I agree with the previous user. I never installed all the patches page download Toshiba, just used Windows Update option in Explorer. So far, I've never noticed some problems.

    If you clean the OS installation I recommend you to install SP2 (if missing) and after doing this run Windows updates.

    I can't tell you much on Intel, but I repeatedly used newer drivers directly from the Intel download page.

  • What should I use: Stand by or hibernation mode?

    What is the general Council concerning power options - should I use (default) stand-by, hibernation or shutdown. This could be for 1 hour or overnight.

    I just used stand-by but sometimes all night I hear the hard disk activity.

    I was wondering the general consensus.

    Thank you

    Hello

    Something this two modes:

    Sleep and modes extended recording the State of the computer when it off s. The next time the unit is turn on, the data will be retrieved and the computer's User Interface will appear exactly how it was when it was turned off.

    The difference between the standby and Hibernation mode is the method of saving the State of the system data:
    -in standby mode, the RAM is used to save the State of the data, and therefore, the RAM is always fed in order to maintain the saved state.
    -in hibernation mode, the State of data is saved on the hard disk, in a special file called Toshiber.dat.

    Standby mode keeps the saved state of the computer for only a few days, that is until the battery is empty.
    Hibernation can persist the State of the data indefinitely, but start and stop times are longer than with the Standby mode and require more energy while saving and recovery of State data.

  • Newly purchased HP Pavilion 11 is already slow and laggy when it is used first.

    Hello. Recently, I bought a laptop HP Pavilion 11 11-e113AU.

    When I started using it, it's very slow. Slow scrolling. Switching Windows is slow. It hangs a little and then continue to work again. I got comments after I posted that I bought this laptop and they said that the laptop is shit and it was a very bad performance. Is this true? I'm really getting worried because I'm starting to believe it works really SLOW.

    Even when you do simple tasks like scroll or transition from window to window, minimize the window and opening a folder, searching for words is slow and laggy. Especially when using Facebook in google chrome. Scrolling is laggy, lag very

    1. Yes, I think that this McAfee product not suitable for the configuration of your computer. It can slow down your computer.

    McAfee may be able to detect the virus/malware but is know that it is not the fast/more lighter AV.

    I suggest you completely uninstall and restart your computer.

    Finally, run the McAfee removal tool

    2. I am not aware of the details of your computer, but in order to change the processor, you will also need to change the motherboard which is not a small change. If it can be changed, my colleagues in the support will be able to respond better.

    However, I don't think that this change is necessary at this time. You/we have not crossed all possible options.

    Let me stress again that these type of mobile computers are expected to generally not to be used for heavy load such as graphic design software (Adobe Photoshop example / AutoCAD) or Machiavellian heavy. They are smaller and lighter than the typical laptio, only 11 inches and mobility is their biggest advantage.

    3. at this time you need not to add 4 GB of additional memory. According to the data provided, you are currently using 1.79 GB of your physical RAM (less than 50%). If you add additional RAM at the present time, this change anything re. performance
