Missing objects - block diagram

Hello!
So... My program it's working fine, but it seems that I cannot see some objects in the block diagram (see the attached image), even if they're working fine. do you know how to show them? because I would like to change something and I don't know how to do that!
I've seen also that if I try to run the clean up diagram function for the whole program labview crashes!
I'm working with labview 2010.
thanks!
bye!

I'm sorry, I forgot to attach the file! Here in this image you can see how it appears (left) and how it should be (right)!
Thanks!
Bye!

Help !!! Up down left right slides missing from block diagram !!!

H E L P !!!! Hi I am right in the middle of editing my labview program and all of a sudden on my block diagram the up down and left right slides have dissappeared from the screen ? How do I get them back ? I have tried closing the program and reopening it but when the saved program reopens the slides are still missing for pulling the programs scope left right up and down !!! Thanks John

Hi,
are you sure the slides (please fill me in what are those?) are missing?
May be you have dragged the mouse while holding down the CTRL-key that auto-expands your block diagram?
To verify use the find function and search for the name of an indicator/control that has gone missing
Another way might be using ctrl-shift-N, this will show a small overview of your VI.

BTW your VI should fit into one (1) or two (2) screen of 1024X768 and never expand it in both directions!!

Bug: Front Panel objects relative position change when placing merge VI onto Block Diagram

I've posted a bug report on LAVA, here:

If someone at NI can reproduce, can I please get a CAR #?

Hi Jim,
After my previous post, I also saw this behavior, so I decided to do another test. If there are no decorations in the VI set to “Merge VI” (“Place VI Contents” for LabVIEW 8.5 and later) the controls and indicators are still not selected when dropping the VI from the Functions palette. I checked this behavior back to LabVIEW 7.1 and it is consistent throughout that controls and indicators are not selected. (Consequently, so is the fact that when decorations are present they don’t maintain the relative position).
I am not sure if this would be better suited as a CAR or product suggestion since it has been this way that long, but it does not appear to be related to the fact that decorations are present in the Merge VI. It does seem strange that the decorations are selected though. Looks like the best way to work around this is to drop the VI from the Controls palette. Hopefully, it’s not too much of a hassle.

This just means that not many people use this feature. However, now that VIPM Professional makes it so easy to edit the palettes, I'm sure that others will start complaining that this doesn't work as they expect.

related to the fact that decorations are present in the Merge VI.
Just look up the functional specifications for this feature and see if all objects are supposed to be selected.
But seriously, is there a reason that only the FP decorations are selected? Surely this would be documented somewhere, if there was a good reason for this current (IMO, buggy) behavior.

That's not a reasonably work-around, IMO. It doesn't make sense to drop Block Diagram components onto the Front Panel. For example, this bug affects the JKI State Machine. It doesn't make sense to drop a State Machine onto the Front Panel.
So, I'd file it as a CAR/bug, and then wait to see how LV R&D feels about it. If they can find some valid reason for why Controls and Indicators shouldn't be selected, then that's fine (and hopefully someone will explain it to me).

Group block diagram objects

I'm almost certain this question has been asked before, but my searches are coming up empty-handed.
Why is it not possible to group objects on the block diagram? I'm using 8.2.1, so if this has been implemented in a later version, you have permission to slap my wrist and send me to the corner for not paying attention.
I think I recall the option being discussed in conjunction with the new "block diagram clean-up" feature of 8.6, but I think the general tone of that was that it would be cool to group objects and have them treated as a single object when cleaning up the code.
I have some code which is generating a lot of user events, and when changing datatype (Typedef) it happens that I need to re-arrange things so that nothing is overlapping. This is a right royal pain without being able to group the event data constant and the create event node together.......

LabVIEW MilliSecs support manager function and Tick Count block diagram object

Is the output of the support manager function MilliSecs (used in a CIN) directly comparable with the time returned by the Tick Count (ms) block diagram object? i.e. if they have the same value then it is the 'same' time allowing for OS specific time resolution

The LV diagram node is built upon the MilliSecs() function, which is
built upon various OS specific functions. It is safe to treat them as
though they are the same function and represent the same clock.

Growing block diagram objects

Recall that with objects on the Front panel, one can select and move them in very small increments by using the control arrow keys.
Is there a way on the block diagram to grow a control/indicator with that same granularity and in a similar fashion? For example, I have picture box that I'm inserting a bitmap into. I want to grow the box width by a miniscule amount, but the normal way of grabbing the sizing handle and dragging it doesn't offer me the desired granularity, as it grows to the next grid line.

... or simply hit the letter "g" (for "grid") while resizing, and it will no longer snap to the grid during the current sizing operation.
No need to change the default behavior.
(g is a toggle, so hitting it twice (or any event count) would re-enable "snap to grid")

How can I open a vi and show the block diagram?

Hi,
I am opening an vi using "Open VI Reference" and "Invoke Methodpen FP", but I want to open the vi and show the block diagram, but I haven´t found any method (Invoke Method) to do that and any property.
Any idea?
Thanks!
Gracinda

OK, I can come up with a reason. I have written a program that will search the entire VI Hierarchy of a program and update all of the descriptions for all VIs with the top level program part #, the name of the top level program that the VI is used in, the company copyright info, the ITAR notice, company address, the name of the engineer performing the update, along with the date and time. This will also place as a background image on all the VIs, a watermark of the company name, legality stuff and the copyright. It works very slick in that if there are thousands of sub-vis, such as what I'm working on now, it goes through all of them, makes sure the data is there as per company policy without having to open every one of them look at them and update or not whichever the case may be. The one portion that is tough is that the program will detect if there is a description written about what funtion the VI performs and if there is not a description, then it pops up a dialog requesting the user to write a description. The problem is that without looking at the block diagram for the VI, it can be nearly impossible to write a description for the functionality of the VI. So is there a way to programmatically open a VI, show its block diagram (this would only be in the case of a missing description) and then upon completion of the updates, close the block diagram? (I already open and close the VI programmatically in order to read the VI DESC and update as needed, but that is in the background and of course you can't see the block diagram).
Thanks,
Dan

Is there a way to add shapes to the shape library, and does anyone make a shape library for electronic block diagrams?

Hello!
I'm trying to use Pages or Keynote to make electronic block diagrams. The shapes library looks like it would be perfect for the job, but the shapes are limited. I know I can make a custom shape, but I live with slight brain damage, which means the mouse is NOT my friend. If I try to make custom shapes, they look like a kindergartener's scrawl, so that's not a solution.
All of the online forums I've been to so far say to use Visio (ick!) and if your desired symbol is not there, make it yourself. Well, several symbols are not there, and the first paragraph explains why this is a non-starter.
I would gladly pay some reasonable fee for electronic shapes, such as amplifiers, mixers, oscillators, etc. if someone made them. But from the help file I can't even see a way to add those shapes to the Apple shape library, so I'm not sure, other than copy and paste, how to handle outside shapes. Copy and paste is pretty labor intensive anyway, but if it's my only option, well, so be it.
Any suggestions? Aside from Visio, that is...
Thanks!
Jim

Hi Jim,
When you say the "Apple shape library" do you mean the Shapes button on the toolbar in Pages?
I don't think there is a way to add to the Shapes in Pages. However, you can create a custom template with shapes that you frequently use. Save a document with your shapes then Menu > File > Save as Template...
This will be saved in My Templates folder, and you can open it with Template Chooser. You will still have to Copy and Paste a shape into the document you are working on. No way around that!
I don't use Keynote, so I may be missing something in your question.
Regards,
Ian.

LabView causes system to lock up when editing block diagram of large application

I am attempting to go through a large application which was written for on a different machine with I/O attached. I am looking at it on a plain PC with no attached hardware. The application loads, I can get into the block diagram, but after viewing it for just a short time the display freezes (including the taskmanager), then the keyboard locks up. The only way out is to cycle the power on the PC. This is running W2K on a 550Mhz pentium III processor with 256MB RAM and a new installation of Win2K with all updates applied. This is with LabView 7.1. I can run smaller subvi's with no problem.
I am new at LabView, so any help is appreciated.

Hi George
what kind of Hardware - IO do you use in the app? are there any DAQ-channel- or VISA-Connection-constants in your diagramm? maybe the problem is not the size of your code but the missing hardware...

Seemingly random node placement on block diagram

When I create an indicator on the front panel, the block diagram node shows up in a seemingly random place. Sometimes it gets hidden. The opposite happens when I create a node on the block diagram. The front panel object placement seems random.
Is there a way to get a container where all things will appear in this box? Can I anticipate where something might show up?

Examining block diagram- ports on VI- How do I determine which port is wired

Trying to figure out how a block diagram is wired with a a vi that has lots of ports. Is there a way that I can identify where the wire goes on the vi?

As tst said, you can triple click to see the entire wire. Some people don't wire properly, with wires going underneath objects. If you look closely at the attached picture, you can see the highlited wire (the one surrounded by dash lines) goes to the top right corner of the object it is wire to.

As I can include a "IVA" in the Block Diagram.

Hello friends. I have a question about how to use the "IVAMATCHPATTERN ALGORITHM.vi" I located in my pc and is part of a library "LLB" but I can not carry it, I get a message that says it was compiled on an OS different. I am working with LV8.5.
Thank you.

Hi Xontrol,
as the error message says: the files can't be loaded because their block diagram has been stripped.
You can load them only in LV8.2.1 - all newer version need to recompile the VIs, which is impossible due to missing block diagram...
Just reading that error message...

Opening VI block diagram engaging remote instrument control

This is a phenomena that doesn't seem to cause any major functionality issues - but I'm still curious how opening the block
diagram window of a VI can automatically engage remote control of any
connected instruments that are powered up - even when the VI itself is
not running? The only problem I have with this is if manual control is needed prior to running the VI.
Has anyone else encountered this issue?

What, exactly, causes the "REMOTE" indicator on your device to come
on? It looks like if you have any VISA resource objects on your
block diagram and open the block diagram, LabVIEW searches what devices
are out there. I would be surprised if your instruments reponds
to a simple query by going into remote mode, but that may be what's
happening. Can you check the manual for your instrument to see
what commands put the device in the remote state?

Need to know how to print in one page a big block diagram from labview

Hi!
I wanted to know how i can print a program i made on labview. The problem is that the program is quite big and i need to print it in one page. Just the block diagram.
Thanks!
Meli

Hello Meli,
I know, normaly your VI should not be bigger as the window screnn.
Anyway, you can use the "Print VI documentation" as explain in the following link and and choose the option "Scale block diagram to fit"

LabVIEW exits while editing block diagram unexpectantly

Hi all, while editing block diagram in LabVIEW 2010, I have experience some strange behaviour from the software. I have two monitors, one has the front panel of main VI and the other - block digram of the specifed VI. When I switch from block diagram to front panel, and vice versa, every now and then the LabVIEW exits unexpectantly without the notice. Upon restarting the program again I get the undo.cpp error. I have attached the error log for my clarification on the type error that I am dealing with. Does anyone have any ideas why this is occuring? Thanks in advance for your help.

Thanks for all the responses.
I was using an existing VI as template to create a new program. There were nested loops in the original program and I needed the logic for the outter loops only for the new program. After deleting many objects in the 'yes' case in the inner loop, I was left with many loose wires in the 'no' case. And that's when my problem started, when I was trying to delete them. Yes, I tried rebooting my PC and that did not help. The problem seemed to get progressively worse, as crashing started to happen even when I was only selecting a wire. But somehow I was later able to select one wire, delete it, and did a save. Then I went to the next wire, and so on. My program is now cleaned up and I'm ready to go on. I will experiment more when the problem returns.
Thanks again.
