Generation of ID of RuntimeStore. Why and how?
Hello
I develop for API 5.0 +, java.
I'm confused about RuntimeStore ID. I read that
-It must be unique and can be generated with eclipse, right-click rights, etc...
-Can I use any number I love
I tried my request on simulators and it worked fine, but when I tried it on a real device and then the returned RuntimeStore and the object that was not put there by me (he has returned an object of NoMoreTransportsException.), so I thought I used a non-unique ID, no doubt. I changed it and now it works OK.
My questions
1. the ID must be unique in the application or the system?
-If a single for the app, so why not use just a series simple as 1,2,3,...
-If only I had the habit of the app, then why is there an object in the RuntimeStore for this ID? (as I mentioned above)
-If for the system, then how can be sure, that the generated ID is really unique? (Long data type cannot hold a real GUID)
2 if I want to put a string to RuntimeStore, how to generate a unique ID? Someone said I should use the fully qualified name of the class, so the Eclipse generated for java.lang.String hash is 0xd4e2de8aa7759716L, right?
-In this case if the id should be unique system, what happens if another application is already using this ID, because it was generated in the same way (java.lang.String-> 0xd4e2...)
Thank you!

2. This is not systemic, used in the world, so no need for the G in front of UID.

Push Apple has stopped working why and how 2016 2 determination
I tried to find the answer myself throughout this community but only to find that others have this problem as well but with no answers or remedies to help. They are at least 6 years... then why not a response to solve this problem eventually. It happened to me several times when I plug my apple device on my laptop. Think that may have something to do with iTunes open automatically? Not sure but would like to know WHY that which is PAST! Thanks for any comments or help understanding of why and how to solve.

I use to manage my DSL modem via an ip address. When I enter FF8 I wonder where to save the file. Why and how can I prevent the FF8 to do this?
And now, whenever I'm in an ip address that I wonder if I want to download the file.
This happens when the modem server does not send the file in text/html, but with a different MIME type.
I tried adding index.html in the event that the server can send this file as text/html.
If your DSL modem has a support Web site, then you can try asking it there advice on how to configure the server modem. -

Lightroom keeps trying to create a second folder "2016" under "2016", then the subfolders with the correct name (date) at import, why and how can I remove the second folder "2016".
One of the possibilities: when you import, you select a Destination folder that contains a subfolder of 2016 in the path (displayed in the green rectangle) when you really want a destination folder that does not have the 2016 subfolder in the path (shown in the red rectangle)

Hi Eva,
Could you please for the preferences of Photoshop, then tab Perfomance.
In here please see, if the option "Use Graphics Processor" must be verified.
These filters are largely dependent on the graphics card.

why I can't change my screen with windows 7 in xp mode and how could solve the problem
Hi tmjmech,
Thank you for visiting Microsoft Answers.
Settings and change integration features
When you run XP Mode, it is possible to change the material and data that are automatically integrated into the virtual pc. To change these settings when in Office XP Mode, click the Tools menu and select settings. You will now be in the settings of the virtual machine screen and click on the category of integration features . From there, you can specify what material and features that you want to embed or share with your desktop computer XP Mode.
These features are:
· Audio - this must be disabled so that you have the best performance. It should be noted that even with this unchecked, all its XP desktop mode will still play through the sound card of your host.
· Clipboard - if this is enabled, then you will be able to copy and paste between XP Mode and your normal desktop.
· Printer - Sharing host your printer with XP Mode.
· Smart cards - XP Mode allows access to the host chip cards.
· Disk - XP mode to access the host players, which include hard disks, CD/DVD players and removable media.
All changes made to the above settings will be persistent every time that you start the XP Mode. However, if you disable the integration of a particular session, you can click on the Tools menu and then select disable integration features. This will make it so that you do not have access to one of the resources of the host. To enable access to these resources, simply click on the option to enable integration features in the Tools menu.
Change the XP Mode Virtual Machine settings
If you find that XP Mode does not work as fast as you want to, or you want to add more features, you must change some settings in your settings in Virtual PC for XP Mode. To change these settings, you must first stop XP Mode so that it is not in a State of hibernation. To do this, click on the menu on Ctrl + Alt + Delete , and then click close on the screen that appears.
When XP Mode stopped, click the Start Menu, select all programs, Windows Virtual PC, scroll down and then click on Windows Virtual PC icon. You should now see a list of your Virtual PC, including Windows XP Mode. Right click on Windows XP Mode, and select settings. Now that Windows XP Mode is stopped, you can change the settings of your virtual machine. The parameters that you may consider to change to increase the performance and reliability are:
1 memory -if you find that your applications are running slowly, then you can raise it so that your applications have access to more memory system.
2 hard drives -you are able to add more 2 hard disks to your Windows XP Mode. So if you need to add another disk to your Windows XP Mode, you can do here. This will allow you to create a second disk on another physical drive of your computer to improve performance.
3. cancel the disks - disks of cancellations allow you to create a base of your installation of Windows XP Mode image and then save all changes in a disc of cancellations. So if you need start from your base image, you just go back to settings and ignore the changes in your drive of cancellations. The next time that you start Windows XP Mode, you will be back to the basic configuration with any changes you have made to scrap. I suggest that everyoneturn this option on because it only increases the safety of your installation of Windows XP Mode.When you have completed your changes, just click the OK button to save the changes.
When you then start Windows XP Mode, these settings will now be implemented.

both my laptop and desktop the same ISP, why and how can I fix
Why does my computer laptop and desktop pc have the same Internet service provider and how to fix it
Hello, your ISP is your Internet service provider. It is Bell Canada, Rogers, Telnet, etc. of Telus. Unless you want to have two companies providing your internet connection, you can not fix this. Your IP address is also the same thing of having 1 service provider. Your Internet provider assigns you an IP address. Depending on the provider, if you unpluf your router, it may be renewed.
