Can you share FP Controls between different Event Structures

I'm creating a program that will either read real-time data from an VNA on the GPIB bus, or read a saved s2p (Agilent) file and analyze it. The FP consists of 5 graphs, and various controls which handle events like printing, changing filters, or exiting. on the BD I have a case structure controlled by an operator selection pop-up. I tried using the same FP controls in the event structures I have setup in each case, as only one event structure would ever be executing at any given time, but the program doesn't seem to like it ast run-time. I've worked around the issue by creating "duplicate" controls and using the property setting to make them visible/disabled, etc., but the is seriously congesting my BD.
Anyone know a way to share controls with seperate event structures?

It sounds like the root problem is the overall structure of your program. I highly recommend that you check out the Queued Message Handler project template in LabVIEW 2012, that will show you how to utilize a single event structure and pass events to a consumer loop. If you program is too large to consider an architecture change at this stage of the game, then there is a workaround for your problem.
What is most likely happening is that you have the event structures all set to lock the front panel until the event completes. However the case structure that you have wrapped around these event structures is causing all but one of these event structures to be unreachable thus preventing you from handling the event. Again, as I stated above, the "RIGHT WAY" to fix this is to select a better program structure but the "kluge work-around" fix is this: Dynamically register for the value change event on all of the controls you are trying to trap events for. Dynamic events can be deregistered and re-registered at run time. This will allow only the event structure in the active owning case structure to be registered for the events, thus no other event structures will get in your way.

Can you share collections remotely between different computers, editors and Lightroom licenses?

I am trying to figure out an efficient way to outsource some post-production using Lightroom. I would like to share image previews that are already organized into collections (with some global adjustments) via FTP. Is there away to share a Lightroom catalogs setting between users and platforms that will retain the Lightroom settings?

I would like to share image previews
Does this mean you don't want to share the actual images, only the previews?
I don't really know any easy way to do this. I know you can use a plugin to extract the previews as JPGs and then transmit those.
Is there away to share a Lightroom catalogs setting between users and platforms that will retain the Lightroom settings?
You could write the metadata to XMP and then transmit the images and sidecar files via FTP, other Lightroom installations will be able to read the develop settings and then render the image properly (assuming you have the same major version of Lightroom on each computer, i.e. Lightroom 5.X can read Lightroom 5.X edits, but Lightroom 3 will not be able to read those edits unless you use an earlier process version)

Can you share iTunes libraries between iPad and iPhone?

I know how to share libraries between my MacBook or iMac and my iPad and/or my iPhone. My question is, can you share your iTunes libraries between your iPad and iPhone only, without using a computer? I wanted to share movies between my iPhone and iPad in Europe over wi fi so I could take more on two devices. Does iCloud support videos?

There are no iTunes libraries on the iPad or iPhone. You have iTunes content on the devices but not libraries. The content is stored in the respective apps as you well know. AFAIK there is no way to share the content from one device to the other using any iOS feature in the current sysetm.
This something that may appeal to you. The GoFlex Satellite Wireless Hard Drvie.

You don't need a computer (other than to set this hard drive and and transfer the content), but it is one more device that you have to lug around with you.

HT204150 can you share icloud contacts between 2 icloud accounts?

Can you share your address book/contacts between 2 icloud accounts? My wife and i have seperate icloud accounts but want to be able to update and access all the same contacts. How can we do it?

Welcome to the Apple community.
The way to achieve that would be for one of you to login to the older ones account in settings> mail, contacts, calendars on their device. They could then enable contact synchronisation in that secondary account and disable contact synchronisation in their own primary account at settings> iCloud.

Can you share purchased apps between a Pre and a Pre 2?

I own a Pre (Bell Mobility) and just got the Pre 2 (Rogers). I probably intend on keeping both.
Question: can the apps that I purchased through the App Store for the Pre (using the Pre's profile and email address which are obviously different than the one on the Pre 2) be installed on the Pre 2 without having to purchase them again?
Thank you.
Post relates to: Pre 2 p102una (Rogers)

Hello bwc565 and welcome to the Palm forums.
My understanding of how the Palm App Catalog works is that purchases are tied to your Palm Profile, which is tied to an email address. It *might* work if you were using the same device and moving a single SIM card between the devices.
However, since you are using two different phone models, and have two separate Palm profiles, I don't think you will be able to move apps from your Pre to your Pre 2 without having to repurchase them.

Can you share a library between two non-networked PCs?

any help appreciated on this one!
I'd like to be able to keep my iTunes library on a portable hard drive.
which isn't too difficult to do - move the folder and consolidate.
then I'd like to take it with me between home and the office.
would playlists / play counts / ratings stay in sync on the external HD or is there no way to do this?
(i.e. would all the listening I'd done at work show up in the library when I plugged the disk in again at home?)
thanks in advance for your help.

If you want playlists, playcounts, rating and such to remain consistent and travel with the drive, drag the entire iTunes folder (the entire folder, not just the iTunes Music folder) to your desired location. Then on each system, connect the hard drive and hold down the Shift key while launching iTunes. You'll be given a dialog box where you can select the iTunes library you want to use. Navigate to and select the iTunes folder on the external drive.
Note: do not launch iTunes until the external drive is connected and mounted, or iTunes will automatically switch back to the default location on the internal drive. No big problem if it does, just quit iTunes and relaunch while holding down the Shift key.
Regards.

Can I share iTunes library between different users on the same pc

I want to know if and how I can share an iTunes library with other user accounts on the same laptop? Can anyone help please.

Jim, sorry, I should have mentioned that permissions issue.
I have a similar setup on a Mac mini. I have the entire iTunes library in the shared folder and on each user account, I point it to that iTunes library file. That way there isn't a permissions problem when multiple accounts are connected to it.
The only problem with that is that each user account connected to that iTunes library can make changes to the library file (ratings, playlists, etc.)

How can I share purchased apps between different apple IDs?

Hi,
I bought a Mac recently and created a new Apple ID.
The Home Sharing for my Mac is 'on'. I want to copy my purchased apps from my Home Sharing account to my Mac. However, I'm struggling to do that.
Can anyone help me out please?
Thanks

A purchased app is associated with an Apple ID. A user with a different Apple ID cannot use the app unless they also use the same Apple ID.
I cannot use my wife's apps nor she mine because each were purchased with different Apple IDs.

Can you share iTunes music w/Apple TV and Airport Express?

Can you share iTunes music between Apple TV and Airport Express?
I have been very happily using 2 Airport expresses to share my itunes library from my iMac to 2 other rooms. I just bought an Apple TV for the bedroom (and I ASSUMED to replace the Airport Express), and can not figure out any possible way to have the same music in 3 rooms any more.
Anybody have any ideas?

I think you may have misunderstood the OP, I believe they wish to be able to walk from room to room and listen to the same music over the tv and the express. itunes will send music to the tv and the express at the same time but in two different streams, so even if you chose the same music over each device it would be quite difficult to sync.

Can i share iTunes music between my kids with different apple id's?

Can i share iTunes music between my kids with different apple id's?

Welcome to the Apple Community.
Yes, even though they have their own IDs for the iTunes Store, if everyone uses the same ID for home sharing, you can share the content.

Can you share music between 2 Apple ID's on the same network?

Can you share music between 2 Apple ID's on the same network?

Welcome to the Apple community.
You can share content between 2 libraries that have different ID's for the iTunes Store, yes.
You need to make sure that both libraries are using the same ID for home sharing though (from the File menu)

Can you share photos between machines that use the same wifi network? Thanks for your help.

Can you share photos on i-photo between machines that use the same network or even between different accounts on the same machine? I know you can share music on i-tunes but can you do the same on i-photo? Thanks for your help.

Yes.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
You can figure out using it with another machine from that too

Silly question, but can you share apps between family members (iPhone)?

My wife has just purchased an iPhone awaiting del.

I would think not as I cannot seem to find anything to suggest it.
But thought i would ask the community.
and is there away around it??????????
thanks again

EDIT: It seems Apple have changed the AppStore Terms and Conditions since I last read them thoroughly.
Here's the relevant sections:
If you are an individual acting in your personal capacity, you may download and sync an App Store Product for personal, noncommercial use on any iOS Device you own or control.
You may auto-download iTunes Auto-Delivery Content or download previously-purchased iTunes Eligible Content from an Account on up to 10 Associated Devices, provided no more than 5 are iTunes-authorized computers.
(ii) An Associated Device can be associated with only one Account at any given time.
(iii) You may switch an Associated Device to a different Account only once every 90 days.
(iv) You may download previously-purchased free content onto an unlimited number of devices while it is free on the iTunes Service, but on no more than 5 iTunes-authorized computers.

Can you share music between iTunes accounts on the same computer

Can you share music between iTunes accounts on the same computer? My kids iPods are under my account now with all of our shared music but they want their own iTunes accounts. I would like to transfer the music and apps that they purchased under my account to their new accounts... Is this posible?

by the way, how can i stop this from happening another time.
Make a backup!
i had music there for over 6 years.
Well you must have updated iTunes once or twice in that time. Do you have some sort of "tidying" app that is supposed to clean "unnecessary" files. If so perhaps it is too aggressive.
