How do I programmatically open block diagram?
Hi, All
How do I programmatically open block diagram of subVI and add frame to event structure
Thanks,
Could you be a bit more specific on what you are trying to do?
Do you want to programmatically edit an existing VI that is currently not running? As mike said, scripting could work but it is unsupported (see the Lava scripting forum for details: http://forums.lavag.org/LabVIEW-VI-Scripting-f29.html). Somehow, adding an event case does not give you much, you would also need to add the code contents and hook everything up to the existing controls, indicators, and other nodes.
If you just need an event that is not always active during run, maybe you can use user events. Check the online help. (Also have a look at e.g. section 4 in the following application note:

How can i avoid to see the source code when any user open block diagram third time without password
i have a probelem regarding source code control. my problem is that when user open block diagram of any sub vi in vi. i would like to make a such a vi which source code can not open after seeing the block diagram thrice time and i dont want to make password to see the block diagram so what can i do ?
give me the perfect solution for this type of problem.First protect you diagram
create a tap on your FP and create a picture of your diagram and put it on the second tap
DON'T expect answers if you only want perfect one's

Opening block diagrams directly
The default behaviour for LabVIEW when one double clicks on a subVI in a block diagram is to open its front panel. For a variety of reasons, this is undesirable. Is it possible to open the block diagram directly without having to look at the front panel ?
When you are debugging code, the default LabVIEW behaviour is, how do I put it, extremely irritating ?Plus, these ideas exist:

Open Block Diagram in Subpanel
In LV 8.6, when a VI is embedded into a subpanel on another VI, when you right-click on the panel of the embedded VI and select "Open Block Diagram", nothing happens. In LV 8.51 and LV 8.21, using the same code, the procedure opens the block diagram of the embedded VI, as it should. I think it's a bug, but I don't know where else I can report it.
Sergey LibermanAndrew, Attached are two LLB's - same code, one in v.8.5, the other in v.8.6. Run mainVI.vi (in matching version of LV), right-click in the subpanel and select "Open Block Diagram". In LV85, the diagram opens, in LV86 it does not.
Regards,
Sergey

Automatically open block diagram on extended monitor?
Hello,
I was wondering if anybody know how to pop-up the block diagram on an extended monitor automatically so that ctrl+E need not be pressed to shift between FP and BD. It would be nice to see FP on monitor 1 and BD on monitor 2(ext). applicable to opening any number of VI/subVIs. (not needing to drag window to ext monitor either)
Thanks in advance,See page 2 of this thread: http://forums.ni.com/ni/board/message?board.id=170&thread.id=102680&view=by_date_ascending&page=2

I opened a VI I recently created and when I try to open the block diagram its greyed out. doing Ctrl I and selecting Protection shows file as Locked(no password) and all options to unlock are greyed out. Any ideas how I can sort this out?
You appear to have done everything right. I doubt that being on the network would be a culprit.
You've probably mapped the drive, right?
Did you even save it with the Locked property?
I am wondering if someone else had access to one of your PC's and played a trick on you.
I tried a test VI and I can open the block diagram. See image below (composite of 2 images)

Close front panel but leave open block diagram
Is there a way to do this? I would like to have my block diagrams of a few subvi's open but front panels closed so my task bar isn't so cluttered. It's not a big deal, I was just curious

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
Windows is a 64 bit extension to a 32 bit graphical shell for a 16 bit patch to an 8 bit operating system originally coded for a 4 bit microprocessor, written by a 2 bit company that can't stand 1 bit of competition. Byte that Microsoft!
Solved!
Go to Solution.Just double-click in an emtpy area and start typing. Use the coloring tool to color the text background.
(there is also a "free label" in the decorations palette, but that seems like a detour )

Can I just open block diagram only
Like I can have only front panel opened. Reason is when I have bunch of VIs
open, I get too many windows to manage even while using 2 monitors. It will
be nice if I can just have the window for block diagram open, if I need the
front panel while editing, I can use Ctrl+E to open it. I know I can
minimize but then all LV windows look same on task bar. Would be nice if
icon of the VI showed up on taskbar buttons of each VI.
vishiYou can use lvwutil/Hide window.vi to hide the front panel.
This method has been around for years.

Nugget: Open block diagram programatically
There are a way to open a block diagram programatically. Exists a undocumented function located in
"%Program Files%\National Instruments\LabVIEW 8.6\vi.lib\Utility\sysinfo.llb\Set Block Diagram Open.vi"My good old 7.1. (ok, I run that in hyper-boost mode ) has a property node 'VI.Block Diagram Window.Open'. Should be available for anyone and documented in 2010.

Open Block Diagram After Deployment on a Non-LabVIEW PC
Hello all,
I have a application created in LabVIEW which will be deployed on a PC which does not have LabVIEW Development System installed in it, but only the RTE. With this application, I am also deploying the dependent VIs in a separate folder.
My question is, is there any way we can open the BD of these dependent VIs in Highlight Execution mode on such PC with no LabVIEW Development System installed? I just want to view the BD of the VI in highlight execution mode, I don't want to edit/make any changes to the VI. Then obviously, we would be needing the LV development system.
Since I've left block diagram (allow debugging) option enabled before deployment, I hope there must be some way we can acess the BD in highlight execution mode. I know that BD get image property works in PC with no LabVIEW Development system installed, so there must be some way or other to access the block diagram in highlight mode.
Can anyone try to help in this?
Thanks in advacne!

"What you think today is what you live tomorrow"You can't do it on a PC without the development environment. If you have debugging enable in the .exe, you can connect to it remotely over the network from a PC with the development environment to watch the execution. Look for "remote panel connection" under the tools menu.

Crash when opening Block Diagram
I am converting a Windows .dll based program to an event driven state machine using my Mac (LV2010) as a development computer. The final program will run in the development environment on a Windows computer. When I reach a certain point in the conversion process, the VI will crash LV while trying to open the block diagram. The VI is broken and always has been because of the .dll and possibly because of some bad wires. I tried rebuilding the VI from scratch and the same thing happened again. I can open the diagrams of the subVIs with the CLFN calls. The .dll file is present on the same directory as the VIs.
Clues: 1. I have had this happen when first opening the BD after restarting LV. Maybe this means I need to work all night and finish everything before shutting down LV??
2. I started with an example VI and was modifying it to include the state machine. Maybe I should build a state machine VI and then add in the camera-specific parts later.
I am attaching a zip file with the VI "testNewCamera.3.vi" and various subVIs, typedefed controls and the .dll. I am also attaching the crash log file.
This has now cost me too many man-hours so I am looking for suggestions.
I am going to save several interim versions the next time I restart this process.
Thanks,
Lynn

lvmaccrashlog2010-11-10-10-44-33.txt 34 KBHi,
The first thing I try to do when I get a VI (FP or BD) corruption/ issue when opening / crash / whatever...is to mass compile all the VIs I have. Sometimes it works, sometimes not.
I was able to open the BD of TestNewCamera3.vi but I am missing a lot of IMAQ VIs and LabVIEW is telling me that a DLL is missing (maybe it is what is causing the crash in your case).
I join the files saved on my computer, maybe you could use it.

How do I programmatically set chart history length?
How do I programmatically set chart history length?
Hi, u could try instead of using a chart, u could use an xy graph with a chart buffer and with the chart buffer defining the length/amount points needed. And this also mimics what happens in a chart.

How can I programmatically detect transition times in a digital waveform
Hi, I have a digital waveform and at certain times I have transistions and glinches , how can I programmatically detect and record the time stamps of the transitions
ThanksLet me see if I understand you. You are reading 14 bits in parallel and you want to know how long between transitions of just one of those bits - say bit 11. Is this bit number constant or can the number of the bit in which you are interested change?
Well, you could XOR the value from each read of the digital bits with the 14 bits you got from the previous read. If the resulting value of bit 11 is true, the state of bit 11 has changed. Use that flag to read/restart an interval timer. Of course the resolution of your measurement will be dependent upon the rate at which you are reading the 14 bit input. If you are only sampling the 14 bits every 500 msec, you obviously won't be able to measure intervals of less than 1/2 sec.
