Which of the three sliders to use?
AFAIK in PL/SQL, there are three ways to define a cursor:1. explicit (with open, fetch and close)
2. with FOR clause
3. with FOR clause (using subqueries)
If there is no particular reasons for the use of one, you have some advice for me to use one over the other (run time, space in the memory,...) or that you usually use all these?
Thank you!
I can highly recommend studied (as opposed to just reading) this article written by Bryn Llewellyn (the guy who ' owns ' inside the Oracle PL/SQL):

"Do SQL in PL/SQL.

My elite 9300z used motherboard Μatx-RS880-H and the specs page says he has 3 expansion slots: PCI Express x 16; PCI Express Gen 2.0; and PCI Express x 1 socket minicards. Two of these slots are already occupied. How will I know if the available pcie slot is Gen 2.0? I want to install a 4-port USB 3.0 pci card.

Looks like the SATA news are messed up. You have 3 x 1 and 1 x 16 slot. They are all 2.0 by the spec. I let someone know here as the page is messed up. Thanks for bringing it to my attention.

I have House part for my iPhone and apple TV, but the iPhone libraries are not listed under computers on Apple TV. I don't see libraries for my Mac. I use the same identifier apple through the three devices. I have an iPhone 6 more working 9.0. The devices are all on the same home network running.
You can't share a library that is located on an iPhone, iPod or iPad with other devices. You can only share a library that is located on a Mac or a PC with other devices. On other devices, iPhone, iPod and iPad for example, you then activate home sharing to connect to the shared library.

To connect the printer to your PC, plug the USB to the USB Port rear, as shown below:

I am facing a problem with the beep.vi. I have a DAQ program, which acquired the signal and compare it to a threshold value. When a signal is out of range, a Visual and sound alarm has occurred. I use the VI beep.vi to generate the sound. Everything works fine except the sound alarm. It gives the table 1 d of type mismatch. I tried to fix this by placing it in a box structure. But it still does not work. If someone could help? Please find attached my VI. Best wishes to all visitors to the Forums of Discussion OR.

Which is faster a bit manipulation to the table or image using the vision
I have to perform an operation on an image. It involves the calculation of the new locations for the pixels for each pixel of the image. Which is the fastest way to do it. Manipulate the pixels as elements of the array for loops, or manipulate the pixels of an image using vision tools?
Thank you.
Hello
If you can use vision tools to make the manipulation of pixels, it is much faster.

is there a widget for Skype that supplies Adobe or if not provided by adobe, which is the more reliable or recommended. Sort again to the use of Muse, but I LOVE it?
For as long that you check your page in time as a visitor, to see if it still works (some designers tend to forget that the web), you'll be fine. Services such as Skype, Google Maps, or Facebook sometimes need to change how their scripts so that they ask you to create a new batch of code and re-only insert in your page. So don't be shocked if it happens.
Good work, have fun!

This program is a benefit to a user uPad if so, how? Which is a huge cost for use!
It is likely that you have either the free version, because there is no way for a company deploy an application you already subscribed (you would have had to sign in and purchase). You can easily tell by opening Acrobat and tapping on the "My account" (in the left panel after tapping "Home icon" in the upper-left). If you look in 'My account' and not logged (and are never online), then you don't pay. In addition, if you only show that you are using "Adobe Document Cloud", then you subscribe to this free service. If you need to cancel your subscription, you can see the article in the FAQ here:
https://helpx.Adobe.com/document-cloud/FAQ.html
If you subscribed via iTunes somehow, you can cancel that with these instructions:
