• Not sure about the best way to structure my app.

  Hello

  I'm not sure of the best way to structure my app.

  I have a main menu that links to 3 submenus, each a link to a number of pages. Initially when I clicked on a menu button, that he would open a submenu instantly and then clicking a button, the page open instantly. And return to the previous menus was also very fast.

  But at some point that he started getting really slow. I click on a button in the main menu and he thinks for a while before moving on to the pick-me-up submenu is too slow. I'm not sure why and I lose a lot of time trying different ways to do it.

  So what I want to know, as far as efficiency goes, should I create the main menu and submenus 3 at the start of my application, keep these same objects active and just pass pointers to them around like settings and pop on and off the screen of the battery when required, or should I just create them as new items whenever they are needed?

  Any advice on this would be greatly appreciated.

  If each submenu returns to the main menu, just use the screen for the navigation stack. Don't forward mainMenu for the submenus; to return, just pop the submenu and the main menu will be back at the top. At the time of mainMenu wants to open a submenu, just push without fun first.

• Not sure about the difference between Lenovo series

  Hey guys, I intend to buy a laptop for daily use soon and many portable computers cought Lenovo my eye (especially for their full ips hd and touch screen), but

  There's something that confuses me on their brand image, what is the difference between:

  Yoga 500

  Flex 3

  Yoga 3

  I could find good in each of them a similar version, otherwise identical specifications, why they cost so differently and what is

  the real difference between them?

  Thank you!

  I checked these two models, and I think it will now come down to personal preference.

  I got the JBL speakers and Dolby ones certified. Two speakers sound great, but I would go with the Dolby option.

  So here's the points in favor of Y500-

  (1) speakers Dolby

  2) more USB ports

  (3) HDMI port (it is a full port and no microphone, I prefer complete ports)

  (4) more large HDD (1 TB + 8 GB SSHD, fast enough)

  (5) it's cheaper

  Points in favor of Yoga 3-

  1) less weight

  (2) small charger (still less weight)

  (3) 256 GB SSD (faster)

  I think that at the end of the day, Yoga 3 will be a little easier to transport (if you travel a lot), and 500 Yoga will be heavier. My personal vote will increase to 500 of Yoga.

  You should probably look at detailed descriptions to see the dissipation of heat and other factors.

  Also, I hope that you are not buying these to make some plays heavy, these laptops are not for good game. They will work some games decently, but nothing too serious. In addition, more the laptop, the more heat it will generate.

• Not sure about the type erasure?

  Hi, my doubt is erase type. Here's the class with generics.
  

  public class Person<T>{
      
         public T add(T a){
                 System.out.println("happy");
         }
  }

  When compiled type erasure happens. I mean when it is converted to type of class erase file arrives. so the code might be as follows

  public class Person{
  
           public Object add(Object a){
                      System.out.println("happy");
           }
  }

  When the compilation is finished, I started to write the main method and in my main method when I declare

  Person a=new Person()

  the compiler generates a warning saying that the Person class is a type of crude. arguments must be provided to the type parameters. So when there is no generic drugs in the class file, how the compiler identifies that the person is a generic class and arguments must be provided to the type parameters.

  Now, there is a basic doubt. so far, I thought that the byte-code and the class file is the same. I mean the class file contains the byte-code which is the reason class file runs on all platforms. I also google to know the difference between byte-code and class file but I couldn't find anything. Class file is different from byte-code. If yes what is the class file and what is byte code?

  The class file contains the byte-code indeed - other elements of prudent information to the virtual machine to actually load and interpret the class file.

  http://docs.Oracle.com/javase/specs/JVMs/SE5.0/HTML/ClassFile.doc.html

  You should do a basic study in binary data formats to understand the functioning of applications with those. Generally, you need additional information, which is usually stored in the top of the file (the "header"), to know how to load and interpret the binary data in the file. These header information could contain generic details for example.

  Take a picture as another simple example file: its impossible to properly load the image data if you don't know at least how wide and height of the image is, how many bytes a single pixel takes upward, etc., then you can just dump the binary image of the file data, you must also store the additional header information.

• Cannot access the disk in the drive E:, please make sure that the drive is ready and the disk is not write protected.

  When I try to backup Quicken, I received the error: cannot access the disk in the drive E:, please make sure that the drive is ready and the disk is not write protected.  My last backup of Quicken was 16/07/2010.  I don't know why I can't back up now.  Is there a way to fix this?

  Why not save to a folder on your hard drive and burn them to a CD - R from there? I can't tell from the little you wrote if the problem is with Quicken (not work or you have incorrectly backup location) or with your CD - RW drive. How about more details to work with?

• Windows cannot be installed on this physical drive of this computer may not support the start-up this drive make sure that the drive controller is enabled in the computer's bios menu

  Hello world

  I know, there are several other threads on this topic, but I couldn't find a working solution. I currently have no OS on my DELL XPS 17 L702X. When I try to install from a USB stick bootable Windows 7 Home Premium x 64 I get this error message: windows cannot be installed on this physical drive of this computer may not support the start-up this drive make sure that the drive controller is enabled in the computer's bios menu.
  I've tried wiping HARD drive and reformat with GParted. I don't really know what I could do.

  I would be very grateful if you could help me

  Hello

  I suggest that you contact the manufacturer of the computer to change the BIOS settings and check if it is has updated the BIOS.

  Important: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  Let us know the results. We will be happy to help you further.

  * Original title: MJTriState

  Someone from the Tristate MJ (not sure of the name), called, saying that it represents the widows team of Microsoft Support. They had followed my computer (Windows 7) and noticed problems with it because it was very slow at startup (TRUE). He said that my computer has been hacked. He gave me my product windows (OK) key and me had discovered my event log that have trouble with my printer. Then he asked permission to take over my computer and fix the problem. At this point, I hesitated.

  The question is done Microsoft outsource monitoring Windows 7 computer in trouble. It seems very likely.

  What I would like is for a picture that I have of the United Kingdom (a map) to have areas on that when the mouse is over it causes a small 'box' opened upward with the details of the address of the shop for this area.

  I have no idea what it's called.

  I assumed it was an interactive image but that seems to direct the user to a URL specified which is not what I want, while option B.

• Adding a folder zipped to the project, not sure of the process.

  DVDs and I wanted to add a folder zipped containing the content in mpeg2 format so that users were able to enter the folder, unzip it and keep a digital copy of the video/pictures.  Unfortunately, once again done with transcoding/writing, he of the disk write-protected.  I'm new in yet, and I'm not sure of the process more efficient, so I was wondering if I could:

  (1) add the folder to the procedure, so once the writing has been done there is the VIDEO_TS folder and the zipped folder "Digital Content".

  (2) change an option that would not immediately hand writing and eject the disk, so when transcoding and writing was done, I could add the folder and then finalize the disc.

  (3) add the folder on the disk before you start construction again, and once the build completed two files would be there.

  Thanks in advance for the help!

  What you're looking for is the content of DVD ROM and simply navigate to the location of this folder on your HARD drive, before to burn to disc.

  Good luck

• How to restore pictures that have been deleted from Lightroom, but not removed from the 'drive '?

  How to restore pictures that have been deleted from Lightroom, but not removed from the 'drive '? Also, how can I restore photos after saving Lightroom. I started to remove some files and it removed ALL of them! I chose the option "cancel delete files" and them brought back, she says they are all "missing or offline. I tried to 'find' a different folder and it deleted the folder all together and now I don't know where he is. Help, please!

  How to restore pictures that have been deleted from Lightroom, but not removed from the 'drive '?

  You need a backup of your Lightroom catalog file before deleting the photos made. You have such a backup? If so, find the backup catalog, open it (double click on it) and then search for the photos you want and select them and then file-> export catalogue; Then go to your original catalog file, open it and select file-> import from another catalog and points to the catalog that you just exported.

  If you do not have a backup of your catalog file, then the only thing you can do is to import the photos again, and Lightroom will treat them as totally new photos with no editing and no metadata provided by the user.

  Moreover, the idea of importing photos into Lightroom and then later removing them to Lightroom should is limited to photos you will EVER want such a photos that are so overexposed or underexposed or blurred that they are essentially useless. The photos that you care enough to run a task on (including editing) should never be removed from Lightroom.

  Also, how can I restore photos after saving Lightroom.

  Is this the same problem as above, or another?

  I chose the option "cancel delete files" and them brought back, she says they are all "missing or offline.

  Is it possible that you actually deleted pictures from the hard disk, as well as from Lightroom? Anyway, Lightroom cannot find the photos and you first need to find photos on your hard drives and then direct Lightroom to the location of the photo on your hard drive, using these instructions Adobe Lightroom - find folders and files moved or missing
