How to Programmatically Find the PrimaryKey Of An Entity?

Hello !
Is it possible to find, programmatically, which property is the primary key of an entity?
Best regards,
Ciro

you are not on an entity but on a entity collection.
check this article where I use the above:

How would you find the pitch period of a sound signal?

Hi
I have a few questions and i would like if somebody could help me even with the smallest comment on this.
How would someone be successfully estimate the pitch period (fundamental frequency) of a 5 second sound file?How would you successfully distinguish the voiced from the unvoiced parts and how would you make sure you dont mix voiced/unvoiced sections? Finally how can you find the exact points where the pitch is at its peak throughout the signal?
Any help/comment/suggesion would be much appreciated

Hello Madgreek,
After some thought I think I may have come up with an algorithm for what we have discussed. Basically, you are interested in knowing the time intervals over which you can observe any given frequency in your signal. As you had suggested, you can examine small windows of your signal and perform FFTs on each of the small windows to determine what frequency content is contained in that window. By examining all of the windows, you will see when particular frequencies are prevalent in the original signal. You'd want to use the smallest allowable window to give you the most resolution, but one that is large enough to cover an entire period of the lowest frequency (so that you don't miss this frequency).
I have attached an example program that performs this operation. The example performs this analysis on an array that represents audio data. I am basically performing multiple FFTs (for each window) and stacking these FFTs in time to form a 3D plot. By examining the 3D plot, I can then see when in time my frequencies of interest are at their peaks. Rather than graphing these plots, you may work out a different algorithm for programmatically determining and logging these peaks and times. I hope this is what you were looking for!

How do I find the cookies I want to keep

Recently I asked for some help but I think my request has got lost.
I had beenadvised to save the cookies I want to keep but this is beyond me.
My question is how do I find the cookie I want to keep? It is a cookie for an ebook and I have no idea what it is.
Will deleting all other cookies mean that it will also delete my passwords and log ins on several sites? I don't want this to happen.
Which brings me to the last point - You say that if I list exceptions to cookies I want to keep (at least I think that is what you mean), how do I find all those cookies?
Again, sorry for troubling you but until I can find out more about the cookies, I don't want to delete these in case I delete the wrong ones, such as the ebook.
Thank you cor-el. I do appreciate your advice...enormously.
Anthony

Dear Sir,
Thank you so much for the above. It will be of great help in telling me where to go. But my problem is that if I can find cookies, I don't know which ones I want to keep. Are they labelled with the sites they refer to? If so that will help me. Apart from one which is the cookie I need to get to my online ebook, I guess there are cookies for the various passwords I have saved?
Forgive me but I am an old man and not real great with computers.
Thanks,
Anthony

In Mountain Lion, how do I find the location of an open Preview File? The file "properties" tab is no longer available.

I typically have several open Preview files at any one time and often forget where, sometimes if, I saved them. In Mountain Lion, how do I find the location of an open Preview File? Tried holding option + command in spotlight but I don't see a path name appear anywhere.

Yes, cmd-option on a file you choose in Spotlight and the path will appear at the bottom of the Preview window.
EDIT: Also, if it is bookmarked the path is in Bookmarks.

How do I find the wifi passord on my iphone?

I sometimes need to get a wifi password at a location i have saved before. my iphone hooks up fine but how do i find the password?

The Time Capsule automatically scans to find the best available channel to use when it is powered up.
You can see the channel that the Time Capsule is using by holding down the option key on your Mac while you click on the WiFi icon at the top of the screen.
On the example below, the Time Capsule is using Channel 149 at the present time.

How can I find the URL for an iCal calendar in iCloud so I can make a link to it on a web page.

I have a single iCal calendar that I want people to access through my webpage. How can I find the URL so that they can view the calendar without having to subscribe to it. I converted to iCloud from .Mac and I can see that changes to this calendar are not showing up.

Mmmh.. i see... I don't know wether it is possible for people just check calendars without subscribing to them... I have been sharing some calendars in my website (maybe you can have a look at it in order to check wether it could be a possible solution for you)

How can I find the location of an app on my iPad 2?

How can I find the location of an app on my iPad 2? The app comes up with a search, but that seems to be the only way to find it. I just installed the app today, but I can't figure out where it is. It has a pretty distinctive icon, and I've looked through all of my apps and even in folders (even though I don't know how it would have gotten there). I want to put it in an appropriate folder under the right subject, but I can't find it to do this. I can use the app, since I can find it through a search though. I have a lot of apps, but I looked very carefully and can't find it. Is there a way to ask my iPad to locate it for me? It's a $25 app and one I plan to use regularly, so I want it located in the folder of my choice.This problem makes we wonder if I have other "missing" apps, apps that I could find if I happened to think to search for them, but that don't appear to be on my iPad (even though they actually are).

You were right about the homescreens. I had turned my iPad off for the night with less than three full homescreens of loose apps, those not in folders. When I turned the iPad on this morning to try your suggestions, I had five full pages of loose apps. They just appeared when I restarted, and there was the app I was looking for, easy to find. Last night I was deleting apps I decided I wouldn't use, organizing useful apps into folders, and making sure I had as few pages as needed by making sure the gaps made by the moved/deleted apps were closed. The missing apps didn't show up at that point; I was just left with fewer than 11 pages. The apps only showed up when I restarted this morning. There were almost three extra pages of apps that weren't there last night. I know there must be other things missing, since all of the pages are full. So I tried your suggestion in iTunes. I connected my iPad, found an app in the alphabetical list on the left, and double clicked it. This brought me to the app's homescreen (and its home folder when applicable), the place where it was located. In order to identify which page that was, I had to scroll through the screen shots of the homescreens that was below the homescreen that was showing until I found the homescreen whose number was in white. Then I could count the pages on my iPad until I got to that page. I'll have to delete more apps and organize more into folders to see what else might show up. There are just too many apps available for special education, and I'm in the process of figuring out which are the best for my needs. Thanks so much!

Hello! I have one iTunes library on my iPod and one iTunes library on my computer. When I connect my iPod touch to my PC, however, I cannot find any files in my iPod except for pictures. How can I find the music files so I can add them to my iTunes?

Hello! I have one iTunes library on my iPod and one iTunes library on my computer. When I connect my iPod touch to my PC, however, I cannot find any files in my iPod except for pictures. How can I find the music files so I can add them to my iTunes?

You can't do that.
And before you decide to store any music that you own on a computer at work, talk to your IT department. Many organizations do not permit it for legal reasons. Standard policies are that anything stored on company owned computers is the property of the company. It could not be legally stored on their machines unless you transfer the licenses and all copies, physical and digital, to the company, meaning you no longer own the music. If they were to be audited and could not prove that they own the music, they would be subject to copyright violation penalties. Just use your iPod when you're at the office if you want to listen to music.

How do I find the FTP info for my site?

I created a site with Wix.com. Since then I've been exploring Dreamweaver, and the author of "Dreamweaver for Dummies" suggets that the best way to make changes to my existing site is to use Dreamweaver's FTP capabailities to download the existing pages. But Wix doesn't support FTP -- so they tell me, and simpleurl.com (where I regeistered my domain name) and which is somehow involved in the posting of my site) can't help either. Here's the Dreamweaver page that I need to fill in.
How do I get this information?

Yup, it's basically free, altho you can upgrade a little, as I've done.
And I took
a careful look at the "source" for the pages I've created. That code will
show
nothing of what I've written -- text-wise. It's all stored on the Wix
servers
and accessed with various scripts. You can re-locate your Wix-created site
after 60 days -- not before. So the suggestion I got from the "...Dummies"
book doesn't apply here.
Nonetheless, I'm going to continue to learn how to use Dreamweaver. Maybe
after my 60 days are up I'll wanna move it. Don't know.

How do I find the iCloud icon to add to the dock

How do I find the iCloud icon to add to the dock. I believe this was on the dock when I first had the computer.

Welcome to Apple Support Communities
iCloud is not an application, so it does not appear on the Dock or Applications folder. Instead, you can manage iCloud settings in System Preferences > iCloud.
iCloud only appears as an application in Windows because of iCloud Control Panel
