Moving controls about on a VI's front panel. How do you get a reference to a 'grouped' set of controls?

Basic problem (annoying, if not disasterous - but common - at least for me):
When you are trying to sktick two different VIs together and you copy the block diagram of one to the other, it sticks all the controls in the middle of nowhere. THen you have to spend about 10 mins dragging the controls screen by screen from one end of the diagram to the other - sometimes over 15 screens. Surely there has to be a better way?
** Incidentally you might think that labview would have these sort of settings in the 'properties' of the control on the right click menu - but no joy.
I guess the obvious thing is that you can write a VI which will get a reference for a particular control and then say set it's position (x,y) to zero. Only thing is that generally there will be a selection of controls, and often they will be organised nicely - after getting them to zero you don't want to have to reorganise them again. I tried grouping the controls, but then the problem is - how do you get a reference to a group of controls. If you move one of them it doesn't keep the spatial arrangement. At this point i have got lost - and easily spent more time than it is worth fixing this problem.
Any thoughts?
Solved!

If I understand you correctly, when you copy the block diagram from the second VI to the first, the controls of the second VI end up in far left field on the front panel of the first, correct? I think these added controls will maintain their relative locations among themselves so you should be able to find them all as a group out in left field. Then it's simply a matter of how to get them to enmasse join the rest of the controls on the front panel. There are a couple of easy ways to do this. There is a button on the toolbar at the top of the front panel window that allows you to reorder/group/ungroup front panel objects. You can select all controls/indicators out in left field and "group" them together. (As an alternative, you can also drop them all onto a tab control which will act as container for them). Then you select this group and with it selected scroll back over to the existing front panel and find and ALSO select (hold down shift key) a control/indicator from the existing group too. Then with BOTH the existing control selected and the new group (or tab control with the new group) selected you use the ALIGN buttons to quickly bring a corner of the new group into alignment with the old control. At that point you can ungroup the new stuff and move it where it needs to be.

How can I get a reference to all controls on a front panel of one type )for example of the type Text Ring?

I'd like to set the strings[] property of all the Text Ring controls on a front panel at once without creating a property node for every text ring. How can i do that?

This is likely more complicated than making property nodes for each
ring, but you can do it. Make a subVI that takes in a panel reference,
reads the array of control references, loops through them looking for
rings, and modifying the Strings[] property on each ring.
The part of this that will probably be the least obvious, when you
have an array of control references there are two ways to find out
if an element is a ring. You can read the classID and compare it
to the cla
ssID of a true ring control. An alternative is to cast
the control reference to a ring control using a Cast to more specific
node and wire the error out to a case structure. The error case is
where the objects that aren't rings will go. The success case case
where you will have a valid ring refnum that you can use to modify
the strings.

Hello Jeff,
Thanks very much for your reply. I looked over the article you mentioned, but I have tried all of these methods, but only get the response "The item “29394D00” can’t be moved to the Trash because it can’t be deleted." Similarly, I cannot Get Info on the file. This is why I'm so concerned, it just appeared on my desktop, but I cannot touch it, or open it or delete it...
If you have any more tricks up your sleeve, I'd love to hear about them...

HT4101 Once pictures are moved from your camera to your iPad (using the camera connection kit), how do you get the photos off of the iPad? They do not show up in my photo stream or my iCloud.

Once pictures are moved from your camera to your iPad (using the camera connection kit), how do you get the photos off of the iPad? They do not show up in my photo stream or my iCloud. I am able to see any photo I took on the iPad using the iPad camera (in iTunes, photo stream, or when I open windows explorer and browse the iPad director), however I cannot see any photos transfered from my camera to the iPad. The camera connection kit must have put my photos in a directory I cannot get to and cannot sync.

I have a new Macbook pro, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop.

I have a new Macbookbook, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop. Also i am thinking once the video is done the fan should be slowing down and getting quiet on its own.

Your fan(s) will run at high speed (i.e., loudly) while video is playing, and you can't get around that.
If your fans are not slowing down within 2-4 minutes after CPU- and/or GPU-intensive usage ends, and the application that was showing the video is still running, Quit that application. (In fact, if you're accustomed to Windows, you may not realize that simply closing a Mac application's window does not quit the application. You still need to use the Quit command in the application-name menu. There will always be a bright dot beside or below the application icon in your Dock for each application that is open.) Quit the ones you aren't using, and see whether that allows the fans to slow down without restarting the machine. If that doesn't do the trick, reset the SMC:

I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do? How can I get the data off this disc? I can see it has been already burned, so files are on there?

Try cleaning the lens and see if that will restore functionality to the DVD drive. Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth) around a business card and insert it gently inside the slot.
If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.

My keyboard moved to middle of page and is split. How do I get it back to bottom of page?

Press and hold the 'keyboard' key at the bottom right of the keyboard and then select Dock and Merge from the popup.
If the keyboard becomes split at the bottom of the screen, or if you want to join it when it's undocked, then you can join the two halves together by using a finger on each half to drag them together (similarly you can then use two fingers to re-split the keyboard). If you don't want the option of a split keyboard then you can turn it off via Settings > General > Keyboard > Split Keyboard 'off'

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

How can i get the reference to Controls from VI-reference

Hello,
i have a VI with ~5 controls on it.
And with the Object "Current VIs path" and "Open VI reference" i can create a reference to the current VI.
How can i create now a reference to the controls? (Starting with VI-reference?
Of course i know how to create directly a reference from a control.
My idea wasm that there areperhaps properties like:
- Number of controls
- Name of control
- Type of control (string, bool. number...)
Is this somewhere there and i just dont find it?
Thanks for your help

Once you have the VI Refnum, it's a two-step process. Wire the VI Refnum into a property node and get a reference to the Front Panel. Output the Front Panel reference into another property node and select the property Controls[ ], which outputs an array of references for all the controls on the front panel.

How do you get your content in front of the right people?

"Outbound Content Marketer of the Year, Joe Chernov (VP of content at HubSpot) told me: Marketers always ask me how to make more or better content, and it’s almost always the wrong question. The right question is: “How do I get my content in front of the right people?” - Forrester's Ryan Skinner
Forrester published a very interesting report in October called "Put Distribution at the Heart of Content Marketing" (here's the related Forrester blog post). My VP shared the report with me and asked me to review and research a key content distribution strategy potentially leveraging the key technologies that are listed in the report. These technologies focus on helping identify influencers, publish content on targeted media properties and publish content if it ranks highly. I have to admit, this is somewhat new territory for me - I've yet to really focus on content distribution strategies across the entire buyer/customer lifecycle and although I've used one or two of these technologies personally, others I've only heard of and some I just flat-out had to Google.
In true intrapreneurial spirit, I starting working through the research phase - I'm actually still working through it - and as I do, I can't help but to start mentally creating a blueprint of sorts... Imagining our technology roadmap interwoven with a content distribution strategy to create and drive a valuable buyer/customer experience (to acquire, keep and grow, of course). Ideally, we'd be able to accomplish all of the above points to significantly - and intelligently - extend our reach moving forward. So, back to the the Forrester report... To help more holistically drive content distribution, Forrester recommends creating a "distribution boss" and linking that person to content creation. I like it. To even further boost success of content marketing initiatives, Forrester suggests: (and I'm paraphrasing liberally here):
1. Your distribution boss needs to be a left-brained analyst with a right-brained way with words
2. Borrow some $$ from your content creation budget for some content promotion
3. Encourage a BFF relationship between your PR and media teams and your content marketing teams
Bottom (or should I say "top") line? I'm looking forward to our organization developing a more scientific content distribution strategy in 2014. Can I get an "amen!"? So, what are you and your teams doing to take a more scientific approach to content distribution in 2014? Or what are you currently doing? I look forward to Topliners feedback!
Cheers!
Kristin
P.S. Technologies currently under review:
- Include your influencers in a distribution strategy: Little Bird, Klout, PeerIndex
- Look to specific vendors to push content on publisher’s sites: Outbrain, Sharethrough, Taboola
- Identify social content winners and invest to amplify reach on the networks that work: SimpleReach
- Keep an eye on emerging technologies for content visibility and distribution: TrendSpottr
- Others: Parse.ly

Alessia,
I agree! In our current blog consolidation project, we're implementing Google Authorship for all our bloggers and we're currently evaluating how to best leverage Deltek's Google+ channel w/in our content strategy. Our PR/Social Director is not a fan - I'm working on, I mean with, her to see the possibilities.
