How to find icon position of currently executed VI on caller's block diagram

Dear forum,
I currently try to use a LabVIEV VI as a simple sequencer: Several (very slow) actions have to execute one after another. Each action is represented by a Sub-VI, some actions are executed several times. My task is to visualize the currently executed Sub-VI somehow.
My first intention (simply manipulate the icon of the currently running VI with "VI Icon.Get as Image Data" / "VI Icon.Set from Image Data" invoke nodes) failed, because this changes the icon of ALL instances of this VI; if you use the same VI several times, the icons of all these VI are changed (see here: http://forums.ni.com/t5/LabVIEW/How-to-change-animate-icon-of-currently-running-VI/m-p/3120754/highl...
My current approach is to use an image of the block diagram (with "VI: Block Diagram: Get Image Scaled" invoke method) within a picture control of the front panel and to work within this control. But for this I need to know the position of the icon of the currently executed VI. I know that I can evaluate Bounds and Position via the GObj properties, but how do I find the currently running VI (note that a VI may reside several times on the block diagram, so the name of the VI is not unique)? IMHO the simpliest way would be if a VI could find its icon on the caller's block diagram itself when executed...
It's clear that this position is not the position on the picture yet, but this conversion is a small piece of work...

Run it in highlight mode, done.
Sure if you don't mind having functional checks taking hours instead of minutes...okay maybe that is exagerating for a simple VI like this, but it would increase cycle time. Honestly I think the best solution would be to use the helper VI that was mentiond before, which keeps track of what VI is running. You can of course use scripting to get the block diagram image, but there isn't a good way to know what exact VI is running using VI server. Here are a few discussions.

Hi all,
How to find out the users currently logged into ODI Work Repository?
Thanks.

Hi,
It stores all the final queries in work rep table i.e "SNP_SESS_TXT_LOG" and the column is "TXT".
Here u can find all the ODI bkp process queries.Pls specify the SESS_NO for purtivular task u want to check which u can get this in ODI operator.
I dont think so that it will keep the substituted value(because its implicit and temporary process) but it will keep all the default values in the table SNP_VAR_SESS and the column is "DEF_V".

Snow Leopard Finder Icons Position

Hi!
Sometimes, when i restart the OS the system arrange the icons positions on the left side of the screen...
I have a lot of icons (using two monitors) and this thing is very, very unpleasant!
Anyone solved this problem?
The genius tech's don't have a clue...
Regards

Hi!
The problem isn't in the menu/option, it seems that when you connect external discs (USB or Firewire) and restart the machine, the icons on the desktop are rearranged by the system itself losing the initial position used by the owner of the account.
If tried some tips found in the web but didn't solve the problem.

How to lock icon position on desktop

I would like to arrange the icons on my desktop in a particular way and always lock them into that position. Is there a way to do that in the OS, or is there a third party plug in that could do that? Thanks.

I agree that the icon arrangement ought to persist through a reboot; AFAIK the Finder is supposed to save that information before shutting down.
Just a shot in the dark: is there a .DS_Store file on the Desktop? (It would be invisible, so you’d need to use Terminal or a third-party utility to look for it.) If you find one, delete it. Another possibility is a damaged preference file. Have you verified the disk & its access permissions with Disk Utility?

I installed two OS in Macpro-Lion and Win7, but I only can select Lion as the default system in the reference setting, how to find icon of win7 in reference setting again?

As captioned, I installed Lion first and then set up the win7 with bootcamp. At the beginning, the defualt system is Win7, I changed as the Lion as the default system in system reference setting. The procedure as follows:
1. Click the system reference setting
2. In the system tool select "Boot Disk", but I only find Macintosh HD Max OS 10.7, no icon for windows 7.
The point is that if I want to change the win7 as the default boot system, what I can do since no icon for selection.

Hi,
When you power on your MacBook, hold down the Alt key and you will be given the option of which OS you want to boot into.

What is a root folder and how to find folders afte...

Can someone tell me what a 'root folder' is and how to find icons once you've moved it there?
It's actually my boyfriend's phone and he uses it for construction site pictures and this morning he woke me up as he couldn't find it anymore. He needs to locate the folder asap as he needs to download pics onto the computer and send them to clients straightaway in batches.
I connected the phone to the computer using the usb cord and it asks for options on the mass storage transfer. I selected 'images' and then on the control panel of windows, select digital still camera. At this point, the computer stalls as it is trying to search for the pictures folder but cannot locate.
I'll never move anything to this 'root folder' again. I was just trying to put the icon on the main menu (the way you can do with a blackberry)
He's already gone for work so took the phone with him, so I thought of giving this forum a try.
Thanks for help in advance

Hi there!
Well If what you did is you transfered the Pictures from one folder to another using your phone, the Root folder is the main folder so lets say you transfered it to the memory card the root folder is the memory card.
Hope tis' help!

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

How to find the feeder class and method which is called behind "Send" button ?
Thanks,

I dont have such.. but you can set external debug point in function module POWL_QUERY_REFRESH
* get the result object type from the feeder
   lr_feeder->get_object_definition(
      EXPORTING
       i_selcrit_values = lt_crit_para " selcrit dependent object def.
       i_langu = l_langu                                     "nt_1673495
       i_type = i_query_data-type
      IMPORTING
       e_object_def = lr_object_def
In I_QUERY_DATA-TYPE you can see name of POWL ID.
Find it in transaction POWL_TYPE and you get name of feader class!

Can we edit the icon that represents our XControl on the block diagram?

I created an XControl in LabVIEW 8.5 (and 8.2.1), and I did add custom icons to all the typedefs and VIs associated with it. However, when I drop it on the front panel, I get a generic-looking icon representation on the block diagram. However, when I create a simple typedef and drop that on the front panel, I get the typedef's icon framed in the datatype-specific border on the block diagram. Perhaps I missed something about how do edit that guy. It's a minor issue, but I'm curious.
Thanks,
Dan Press

Right click the XControl itself in the project and select Properties. There you'll see an icon that can edit, which will show up on the XControl on a block diagram.
... Michael beat me to it!
