Has anybody here designed their own server VIs for use w/ DSC?
I've been browsing viserver.pdf and the DSC documentation to understand what needs to be done to implement a server VI for DSC... but I'm finding the documentation difficult to understand.
I understand the basic 3 tiered layering of DSC with a GUI VI on top, the Tag Engine in the middle and the server VI on the bottom aquiring data directly from the device in question.
Is this server VI supposed to be programmed as if its a driver - sending low level(GPIB in this case) commands to the device to write and read info? I guess where I'm hung up is here: I've already written a driver for my temperature controller device and w/ this taken care of, I'm confused about the roll of the server VI
. Should the server VI use the driver to aquire data from the temp controller or should the server VI itself be the driver and server combined?
I've looked at some of the server VI examples that come w/ LV but I'm relatively new to LV and have almost no time w/ DSC... so the examples aren't helping much.
Any direction or tips for a DSC beginner using a server VI would be great.
Thanks,
Jim
Perhaps a simpler solution for you at this time would be to use the driver VI that you have already created to serve data to DSC. This is done by writing your data to memory tags. Once your data is stored in a memory tag, all of the functionality of DSC will then be available (logging, alarming, security, trending, etc).
National Instruments offers basic skills training courses for many of it's products, including DSC. I recommend that you attend the LabVIEW Basics I and DSC Basics courses. All of the information that you need to perform the above operation are covered in these courses.

We have multiple devices in our family. On each iPad/iPhone each user has their own apple id for iMessage, Facetime and icloud, but we all sign in to the same apple id for itunes. When one of my kids comments on my shared photostream, it shows my name and not theirs as the commenter. How do I fix that?
CREATE A NEW USER
Go to System Preferences --> Create a New User in Users & Groups
Decide on whether to setup as Admin or Standard User.
Switch to the New User by logging out under the Apple in the Menu Bar or use Fast User Switching
Fast User Switching allows other users to leave current applications and windows open. Depending on RAM, you might need to log out rather than use FUS. -

Has anybody ever forgotten their 4 digit passlock code to their iphone 4???
I'm assuming you want to know how to deal with this rather than starting a social network...
Restore the phone in iTunes using the computer the phone syncs with. If you use any other computer, you'll be asked for the passcode to restore. In that case, you have to force recovery mode and lose all data on the phone. Search "recovery mode" to find out how. -
I had an iPhone 4S, I recently upgraded to a 5s and have been using it since early December. I kept my same Apple ID . I gave my 4s away, the person set up their own Apple ID for the 4s however now I can't use my Apple ID in my 5s. Any help please
There could be many causes. What happens when you try to use it. also try adding it again.

How do you change apple id for icloud if phone is already set up. Need to give each phone in my account their own apple id for icloud so that we dont receive each others messages but can still all use same id for purchases.
Settings-icloud-scroll to the bottom, select delete, if you want to keep the content select keep, otherwise it'll remove it. Then once it is done add the account information for the account you want on that phone. Your apple ID in settings-store will remain the same and each device can still purchase/use content from that account.

Should each member of the family have their own apple id for maximum icloud storage?
Welcome to the Apple Community.
It would give you more storage, but more importantly it will stop all your personal data getting mixed up. -

How to design socket client-server app for 2-way communication
Hi, I am writing a client-server application. I have a single server and many clients. Each client will need the ability to send information to the server at any time. The server will also need the ability to send information to a client at any time. Its this second part that I am not sure how to design. Would I need to create a SocketServer on each client to accept incoming messages, or is there a better way? Thanks

Don't my requirements sound a lot like an IM application, where a chat server might need to send a message to a chat client at any time?Not really. If that is what you are designing
in my opinion one could easily be forgiven for thinking you were deliberately obfuscating your goal...
How does the server know where the client is? Does it know the IP address of the client?I would imagine the server would contain a directory of IPs? I'm not sure.
What happens if the client is not running?Then I guess the message would not get delivered.
What happens if the client is behind a firewall that does not allow incoming connections?How do IM chat clients work? How have people solved this in the past?Typically the server would only care about clients currently connected to the server.
Maybe you should re-think your design. I don't really have a design, just requirements, that's why I'm writing this post.Your subject says "+How to *design* socket client-server app for 2-way communication+".
Are you saying you expect someone else to do the design for you? -
My children both have ipad minis - I want to be able to purchase them items using my applie id but I want them to have their own apple id for imessage etc...is this possible?
Your Apple ID can be associated with up to 10 devices, including iOS devices, computers and Apple TV(s). If you will still be within this limit, you can continue to share the ID across all your devices. A caution about sharing your iCloud account, however: when you share an account any data you sync with the account is merged and the merged data appears on all devices sharing the account. You may, for example, end up with each other's contacts and calendar events on your devices if you do this.
It's usually recommended that you share your iTunes account, but maintain separate iCloud accounts, as well as use different IDs for iMessage and FaceTime (to avoid getting each other's text messages and FaceTime calls). Note: the ID you use for iTunes purchasing does not need to be the same as the ID you use for other services such as iCloud, iMessage or FaceTime.

Has anybody NOT returned their battery after the recall?
My battery is eligible for the recall, and I've submitted the form online. Like it's been stated in other posts, Apple never asks for any credit card information. Despite the potential problems of continuing to use a bad battery, has anybody decided not to return theirs? Has Apple tried to charge any of you? What's the deal with this? Right now my current battery is holding up just fine and I'd like to continue to use it as long as it is functioning normally. Thanks.
I have week 19 17" MBP.
You may not be in the "recalled" range week 19 seems a little late.
1) I never received any information on a battery
recall.
Apple did not send out information, you need to crossreference your battery to a list online
2) My battery seems to be working fine.
That's great, your battery may not be one of the "recalled" ones. If it is, it can still function properly (for now)
3) I recent sent the MBP in for a MLB replacement. If
the battery were defective, would they have replaced
it then?
Not always. Apple would have let you know on the invoice if they replaced your battery - there must be a paper trail of what they did.
So they either didn't replace it because:
1. you were not eligible
2. they did not look
If I were you I'd click on the "support" button and search for MBP battery replacement program to check to see if you're eligible -
Design your own hard case for the iphone

Anyone got any ideas where I can go?
Let me know if you've found a customizable iPhone case supplier! Thanks!

I recently purchased the iPhone & i would like to pass down my iPhone to my daughter (who is 8) so that we can iMessage & FaceTime. I intend on having my AppleID on the phone, so i can restrict purchases from iTunes & the App store. Any suggestions on how to get an iCloud account for her, even though she is under 13?
Each user should have their own icloud account, otherwise they end up getting the same emails, contacts, calendars, notes, reminders, etc. - usually not what you want. But if all have been sharing the same itunes ID, keep it that way, you can have different IDs for itunes and icloud.
If you already have another icloud account, and want to set it up on a device, then go to Settings>icloud, scroll to bottom of screen and tap Delete Account. This only disconnects the device from that account, no data is lost on icloud. Then enter the account ID that you want to use.
To create a new icloud account, go to

We Have set up 5 differNet apple devices ( iPhones, I touches and iPad) so that they all use the same apple I'd and password. I would now like to give each family member their own apple I'd and password. Can I do this without loosing any of the data on each persons gadget? Thanks!
I think I will do this. I will use my apple ID and set face time and message to work independently. That solves one problrem. My other problem and maybe my bigger problem is that if I am using my apple ID, how do I iflter all of this so that my kids don't see my contacts, get my apps, etc. ?
