  3. Now we are digressing a bit but I also have an old piece of marketing I like to show off inconspicuously. At NI Week the last few years NI has various buttons that say phrases for that years' theme. Usually people grab a handful of buttons and put them on the lanyard you wear with your badge on it. I won't go too over board but I'll grab a few and put them on, but mixed in with them is a LabVIEW 7 Express pin I was given years ago by someone that was at NI Week the year LabVIEW 7.0 Express was released. It is old enough that it is starting to rust on the back a bit but LabVIEW 7 (and 7.1)
  4. I don't have anything to add other than I've seen this but not in any recent projects I've worked on. It always frustrated me when I'd drill into some VI that was taking forever and it would be some property node or Read/Write/Open that was supposed to have a small timeout.
  5. One quick comment on the can opener thing. I might well be using the can opener incorrectly, and I'll try the horizontal way next time, but I think my habits came from an old wall mounted can opener I used at my grandparents for years which was vertical in design. Also I included an ad for it because the thought of giving a can opener as a perfect gift to the "queen of the kitchen" would probably not go over well.
  6. In the Facade, set the background pane color to the transparent color value. This doesn't make the facade transparent when developing it, because...well it can't really. I believe when editing the VI the pane will appear black. But when the XControl is running in a new front panel, it will have a transparent pane color, meaning it will be the color of the front panel on that VI. The transparent color value is 0d16777216. https://forums.ni.com/t5/LabVIEW/Can-a-Color-Box-display-the-transparent-color-16777216/td-p/172288 Also is this documented somewhere or just tribal knowledge?
  7. So when I was playing around with this I would map my build folder, to the www folder of my webserver, with a symbolic link. This way I would build and it would already be in my web server folder ready to be used. Here is a very loose set of steps I did to map a folder from a build to a place that the webserver uses. I don't know of what NI uses on the hosting side and I've always just used XAMP which is Apache. Windows has a built in server too that works well enough for basic stuff.
  8. The "Check your internet" is a catch all error basically saying it couldn't install, and it must be because the internet is down right?...right? For me I got that error when I had a bad stick of ram in a computer, and it would uncompress a package, and then the CRC would fail. I'd restart the installer over and over until it worked but the computer had all kinds of other problems. The Offline installer including drivers and several other things is a bit crazy. I mean will the community edition also be 25+GB in size? I'd usually download the whole developer suite in the past anyway so
  9. It really depends on what you are trying to do so I get that. For me even just setting the VI file to read-only would be enough, but I ran into a few times when a mass compile would want to overwrite the VI despite it having separate compile code, but that was years ago. For me the purpose was that a developer would be drilling into the code and not realize they were in a reuse function and would start messing around with it and changing things that will now make the program behave differently on one developers machine, than the others. A gentle reminder to not mess with something was all w
  10. Not trying to derail the thread even more, but every time I hear that argument I say that is why you can lock a VI without passwording it. Which is what my Pre-Build action on building a package does. Need to edit it and do a test? Sure just unlock it. Drilling down into a VI and not realize it is part of the reuse library? You will when you see it is locked. But whatever. I still tell the quote from NI R&D saying off the record that the protection you get from password protecting a VI, is about the level of protection you get from tissue paper.
  11. Oh yeah I forgot about that. This is the Salt that gets applied to the MD5 of the password. Starting in 2012 NI started salting the block diagram passwords. The salt that gets applied is something like the number of all String, Path, and Numeric controls connected to terminals. I think this does go into clusters and arrays so the work actually needs to be recursive. This ends up being a 12 byte salt, but I think 9 bytes are always 0. Of course you don't need to do all of this, to figure out what the salt is. I mean all you need to do is guess three numbers, all of which are the numb
  12. When a VI is in a library, the password is stored in the VI, and in the library, and there is some kind of link in the password of the VI to the library, in the VI. So if you recreate a VI, and it doesn't have a password but the library does, or if the two passwords don't match, then you will get that error. Now that I'm searching for it I can't find much, but Flarn also had some code for getting file structures of a VI. His personal site had a few things but seems to be down at the moment. http://flarn2006.dyndns.org/llvim/#downloads Just be aware that most of his stuff is vi
  13. I reversed the PHP code into LabVIEW here as well, adding just a few features. Also you've probably come across Flarn's stuff, he has some code for object deconstruction getting into pulling out and manipulating objects in the LabVIEW source. Which is neat but probably isn't what helpful for what you are doing.
  14. It is not. They will not. As stated this is how all programs work. You cannot keep the executable safe, while also having it be open enough to execute it. I do hope you share anything you discover with the community, I just expect what you will discover is that reversing a binary of any kind to its source will take forever, be error prone, will be incomplete, and won't be very useful. This will especially be true for LabVIEW as the tools for this disassembly are less mature than other languages.
  15. This likely won't get you very far. Yes you have the files that are in the EXE extracted which is useful. And in theory you should be able to add all those files to a project and rebuild it. But if you are trying to do this so you can rebuild in a newer version of LabVIEW, or so you can edit some part of the EXE, then you aren't going to be able to. When a set of VIs are turned into a binary, they are compiled for that that target and runtime version. Then in almost all situations the block diagrams are removed, and in many cases the front panels are removed. What is in the EXE is th
  16. VIPM packages support Post Install VIs, and Post Uninstall VIs, and in there you could have a VI that edits the LabVIEW.ini file to add or remove things. I also don't have a 2009 machine to test it with, but if this ever became an official thing I'd encourage the use only after the point NI made VIMs official. I didn't use VIMs in pre-2016 for anything real just experimenting and don't know the stability of it in earlier versions.
  17. Oh another consideration with this is currently OpenG Array tools work in LabVIEW 2009+. This would make a version which would only be compatible with 2017+.
  18. SMorRES - Scalable, Modular, Reusable, Extensible, Simple. I do like architectures and frameworks to be simple, but not at the cost of scalability, modularity, reusability, or extensibility.
  19. Sure, why not. OpenG array tools are great but could have used improvements over the years, from inlining, to conditional terminals, and now VIMs. But to pump the brakes a little, I heard some rumors NI might also be in the works trying to make their own VIM array functions. No solid timeline and no idea what functions they are tackling, or distribution method. Then again we don't need a rumor about what NI might be doing to dictate what we are doing. Also I have no idea who is in charge of OpenG, or how to contribute to it. <shrugs>.
  20. I just tested on a fresh 2019 machine and I also needed SuperSecretListboxStuff=True in my INI.
  21. Well some of these posts are from 11 years ago, and there have been lots of back end changes since then. We try to keep all the content we can but in some migrations things are lost. That being said I can download the newest attachments. A while ago before I was a moderator there was a pretty catastrophic crash with all content of the forum being lost. One such awesome engineer realized he had setup subscriptions to the forum, and would get an email for every reply someone made. Because of this he had a record of all communications made on the forum and provided it to the site admin.
  22. Well I'm a bit confused. When I made this post I know that I was able to copy the 0px splitter, but now that I'm attempting to I can't get it to work. I'm in 2018 SP1 f4 now but doubt that extra patch level broke this feature and more likely I did something different then, or it copied it as 2px and I didn't realize it. I think a more useful thing would be to have a VI that can turn a selection of splitters into 0px ones, or back into 2px ones. This VI could be invoked on a VI and then it would make editing and positioning them a normal process. But Flarn's magic eludes me.
  23. Since 2011 I've been refining what I call Glued (Global User Event Driven) architecture. It is User Event driven using a publisher and subscriber model, with variants and variant attributes as the data containing things like the Request Data, event name, who requested the action, who is to perform the action, and GUID among other things. These parallel actors default to non-reentrant so that probing and debugging is easy (and possible on RT), and don't get spun up or down but instead have a known number of them at test start. They all start at once, and they all stop at once. If an act
