Hot to disabled the "Block Diagram to show" for other users?

Hi,
I am doing a LabVIEW program that other persons may use.
I need them NOT to be able to access the "LabVIEW Block Diagram" (by doing e.g: Ctrl + E).
How can I do this?
Kind regards,
Amaloa S.

Hi Amaloa,
You could achieve this by:
- Click File (on your front panel) > VI Properties
- On the Category drop down list, click Protection
- Select Password-Protected
- Enter New Password and varify it again

Files added to server take time to show for other users

Various users add files to server and other users with folder access cannot see files for sometimes up to 2 hours before the files appear. It is not a rights issues as when the file final appear in the directory they can access the file and use.

I saw this at a client's setup. Upgrading the client computer to 10.10.2 resolved this issue.

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!

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

Why Is the Block Diagram Disabled?

What did I do now? Please look at the attached image. A VI that I am using as a subVI in various different programs suddenly started looking like I had used application builder to create an exe file out of it (But I didn't!!). The only options are Start and Run Continuously, and the block diagram is disabled. What did I do to get myself in this mess? How do I undo whatever I did, so I can edit the block diagram again? Any help or suggestions would be greatly appreciated.
Thanks!

Did you ever built a source distribution with the option set to remove the diagrams? In this case, the original must still be around somewhere.
Since LabVIEW 8 you can no longer simply save without block diagram and you would not be able to upgrade such a VI to LabVIEW 2011, which it is now. (details)
Of course it is possible that there is some corruption, but looking at the memory usage, the block diagram is blanked out.

Disable (all) functions on the block diagram with right-click menu

Hello to everyone,
here is one more idea, which I'd like to propose.
As for me, it would be useful to have the following: when all components (functions, wires, subVIs, etc.) are selected on the block diagram (like, after ctrl+A), operator could do right-click, and in the menu would appear menu item "Disable everything". After it, all the code could be placed into Disable structure.
Of course, I can add Disable structure to block diagram manually, and cover whatever I want, but with right-click menu it would be much faster.
Also, it can be modified to disable only selected items - then each of them can be placed into separate Disable structure, and, for example, additionaly in the enabled case of Disable structure, corresponding wires will be connected. Sometimes it is needed for testing - just to disable couple functions, and test subVI. Or to disable subVI fully (it's faster, then disable place, where it is called. Especially, if subVI is used in many places).
It will not make debugging difficult, because anyway Disabled structures are used; such functionallity can just make life a little bit easier...

There is always the File->New... which opens up a new window. You can have your templates in that window by putting them somewhere (I don't remember where at the moment).

I am trying to create an executable vi that will call out another vi and show its front panel in the executable. When I try this I recieve this error message "top level vi (my main vi) was stopped at unknown on the block diagram of (my sub vi)

I am trying to create an executable vi that will call out another vi and show its front panel in the executable. When I try this I recieve this error message "top level vi (my main vi) was stopped at unknown on the block diagram of (my sub vi)

Well the most common way is to enclude the vi's in the build spec either directly in the dependancies that the App builder automatically generates OR by declaring them in the build spec as "additional enclusions" (like you must do for dynamic vi calls in your app.
I have heard rummors about My.app Stuff.vi in a nugget Intaris posted- and I've wanted to dig deaper into Intaris' claims- but have not tried it myself.
If you go down the stuff.vi route Keep us curious guys posted

Why cannot the block diagram view of a VI show the "connector pane" view in the UR corner, like the front panel view does?

Perhaps there is a good reason for this that I just haven't figured out. I haven't seen any questions about it searching the NI site, however.
But it just seems totally inconvenient to always have to go to the front panel to get to the connector pane view, especially if some of those connectors are hidden. Then I have to go to the block diagram, guess which control/indicator I want to unhide, go back to the FP to check it on the connector pane, then go back and hide it again, and repeat if necessary. Even if the C/I is visible on the FP, it's still an extra step or two.
When I'm building connections using the block diagrams and planning where to put connectors in subVIs so they would be easier to wire up (line up inputs/outputs on sides, not have to go top-to-bottom, etc.), it sure would be nice to be able to work totally in the block diagram realm.

LabView application hangs up when scrolling the block diagram

Hi all.
I attached you "Main.vi" that is part of my LabView project. I don't know what's going on, but when I scroll the block diagram to the maximum right, the LabView application hangs up. There are a lot of things in this block diagram because is an outline yet. My plan was to make it more structural, but now I can't do anything because this error don't allow me to edit the diagram.
Please, try to open it (ignore all the dependencies) and check if it hangs up also in your computer.
If it does, is there any way to recover it? It's really important for me because I don't have any backups since two weeks ago...

Francisc

It didn't hang up on my computer, but it did make me nauseous, luckily I keep a bucket by my desk.
You might have video card issues. Try this: open the VI, and hit Auto Cleanup, then save. Close LabVIEW, reopen. If that does not work, try to get to the far right side by going to the Front Panel, and double clicking something that will take you there. If you get there successfully, use the disable structure to disable ~ 1/8 or more of the diagram on that side. Save, reopen.

I cannot display the block diagram when the VI is running

It is not possible to show the block diagram while the VI is runs. The frontpannel remains on the screen. When the VI is started from the block diagram, the frontpannel pops up and stays on the screen

Are the VI Properties >> Window Appearance... set to dialog or modal? That could keep the front panel on top.

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

Place an image on the block diagram

Is there an easy way to place an image on the block diagram?
To clarify, I would like a simple way to paste a bmp or jpeg or png or whatever onto my block diagram for the purpose of documenting the block diagram for future programmers.
The way I currently accompish this is by creating a picture constant on the diagram and running a seperate vi to load a picture into a picture window, then using copy and paste functions to get the image into the picture constnat in my block diagram.
There's a simpler way, right?

Thanks, but that isn't at all what I am trying to do. I want to
place an image on the block diagram, not read an image. I've attached a
screen shot of my block diagram to show you that I am using an image
that I pasted onto the block diagram to document the block diagram. The
picture below the wiring is a schematic of a rectangular reticle that
corresponds to the wiring diagram above. You can see which points go
where when drawing the targeting reticle around kermit the frog, so it
is easier to understand the wiring diagram.
The method
I have to use to paste an image into the block diagram is cumbersome. I
would like to know if there is an easy way to paste an image into the
block diagram.

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,

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.

On the block diagram, clicked Express - Signal Analysis, I don't see Statistics.

On the block diagram, I clicked EXPRESS - SIGNAL ANALYSIS , then all I get are SIMULATE and HISTOGRAM. What happened to the rest like SPECTRAL, TONE, STATISTICS, etc.?

(Well, if you get a sine wave, you are probably simulating one. )

After I remove the Block Diagram, The VI under RT target is always broken.

Why the VI is always broken under RT target if I remove their BD?
My LabVIEW Version is 2012 f1. I remerber that I have done a lot of remove in the last year and works well on RT. Really don't know why it's not work this time. Even for a very simple diagram...

I removed it's BD and put it under a PXI Real-time target. It says:
"This VI has a bad connection to or cannot find a subVI or external routine but it has no block diagram to show or fix the error. You must find or correct the subVI or external routine. Check for more information in the Explain dialog box in Get Info."

How to add text to the block diagram

How do you add plain text to the block diagram for documentation and can I change the background color to yelllow or something else that may be helpful? see image below

Just double-click in an emtpy area and start typing. Use the coloring tool to color the text background.
