The Block diagram that cannot be edited...

The customer wanted to launch the application ( done in LV7 ) with a shortcut from the desktop and when done with it wanted to close all including the LV environment.
So I made the following changes :
1. Made the application to "Run on Open "
2. Connected the while loop Stop button to the "EXIT" function.
3. Saved and started the application.
Presto!! All worked as expected. Except that I no longer was be able to Edit the block diagram !!
Good - I had a copy of the code before the change and survived the nightmare ....
So the moral : Be very clear of what you are doing before you use the EXIT function.
Just though will share the experience, before somebody makes the fatal mistake as above.
( I have now ordered out my copy of the Application Builder, so that I can have my editable code well away from the customer's PC.)

Here's another way to do it.
Create a directory in your LabVIEW x.x directory named 'wizard', and save the attached VI there. If LabVIEW is running, you'll need to restart it, but then in the 'File' menu, you'll have a new selection named "Supress Run on Open...". Select this and you'll get a browse dialog to select the VI to open. It opens it by reference so it will not run.
This is saved in LabVIEW 6.1, but works fine on 7.0 and 7.1.

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.

I transferred a pages file from ipad to mac (also pages) via email for editing. However received message that cannot save edited document to the mac because "trial period has expired for iwork"! I have purchased pages for both machines separately. Ideas?

I transferred a pages file from ipad to mac (also pages) via email for editing. It opened normally. However, after editing, received message that cannot save edited document to the mac because "trial period has expired for iwork"! I have purchased pages for both machines separately and presumed they would work without a hitch. Am I missing something?

It used to be that to update the trial to the licensed version with the box, you just inserted the DVD & ran the installer to convert the trial to licensed. This changed with Snow Leopard. You now need to delete the trial & then reinstall from the boxed DVD or the Mac App Store. The files to delete are the iWork ’09 folder from the main HD > Applications; the iWork ’09 folder in HD > Library > Application Support & the individual iWork application plist files found in HD > Users > (your account) > Library > Preferences for each user.
Yvan Koenig has written an AppleScript that removes the files. You can find it on his iDisk in For_iWork > iWork '09 > uninstall iWork '09.zip.

Cannot place custom subVI on the block diagram

When I press the "Select a VI..." button on the function palette and select the VI I want to place on the block diagram nothing happens. This only seems to be happening for two particular VIs. Most of the time I can place the custom subVI without any problems.
Is there some option that could have accidentally gotten set that does not allow a VI to be placed on another VIs block diagram?
Please let me know if there is any way to fix this problem.
Thank you,
David R. Asher

David,
What you sent me has a .ctl file extension. The ctl extension is for LabVIEW custom Controls, not VIs. Even though it is actually a VI, the wrong extension must be confusing LabVIEW and not letting it load. It's probably trying to put it on the front panel since that is where controls go.
If you change the ctl extension to vi, it works as it should.

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.

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.

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.

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...
Regards,
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.

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.

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.

Labview: Null Window ... stopped at unknown on the block diagram

Hi,
I have a fairly large program that was written in Labview 6.0. Recently we upgraded to Labview 9.0 and this program was exported to an executable with the new version.
When running the executable I sometimes get the following error as seemingly random places. I have not been able to make it crash when not using the executable. Labview: Null Window. The top-level VI ".vi" stopped at unknown on the block diagram of ".vi"
I apologise for having to blank out the vi names but i cannot give vi names, say what the software is used for or give over code. I can say that it uses NI USB 6212 IO cards, interfaces with Rhode and Swartz instruments and uses alot of file IO.
I was hoping that someone could give me a hint on how to debug such an error. I have noticed that When this error occurs, the memory use almost doubles.
Thankyou
James

I think you open the front panel of a VI that has it's front panel removed during the build. Try to adjust the built settings of that specific VI to include the front panel.

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

why TMG didn't block this pasword protected archive ? it must block according to this option : ( "Block Files That Cannot Be Scanned".
any help ?
thanks in advance

Hi,
Thank you for your post here.
Before going further, we must make sure that we have enabled Malware inspection and we need to note that web protection need license.
Please follow the steps below to verify if your malware inspection is enabled meanwhile update the latest definitions.

Additionally, you could try to check both “Block encrypted files” and “Block Files That Cannot Be Scanned” options to see if it works.

hi quan, thanks.
malware inspection is enabled with evaluation license & is not expired.
both chek marks are selected but it again doesn't block password-protected rar files. if possible please test that.
