  1. Just to add, in 7.1 we have external nodes, not XNodes. External nodes are said to be even more problematic than XNodes and will not be supported by some version of LV (I don't know if it is already discontinued or when it might happen). This prevented me from looking deeper into that issue, as I have some ideas to use them. But having 'rusty nails' code that breaks and no one except you has any clue on how this was done, I think of it as a really bad idea. On the other hand, in the informal documentation on external Nodes, there is a merge error VI, with the same behaviour as the build array
  2. QUOTE (Justin Goeres @ May 8 2009, 02:40 PM) Not correct, as the 0 isn't coming out of the I when the loop executes 0 times, the tunnel is giving the default value of 0, which is the same as the I terminal output on first execution. My only 'wish' would be, that executing a loop 0 times would resulat in a different value as executiong it 1 time (be it -1 as default value or start counting at 1). But I'm sure it won't be implemented, as it would certainly break a lot of existing code. To push that point a bit further, I think that for loops of iteration 0 are potential troublemakers. If y
  3. QUOTE (jdunham @ May 7 2009, 08:19 AM) Can you hint me how to automate these nightly builds (and tests). And furthermore, isn't that an option to just buy one single license ($$) of the application builder for the whole team, as only the developer 'responsible' for the nightly builds will need to install it? @Joe Z: I'm mainly searching for software/tools, as we are settings up a network based development enviornment. Later on it will be moved in the grip of the IT-gods. But for now we are free to experiment around and and choose the software. The books are meant to get some ideas of w
  4. I've got both constants in 7.1 For loop: if you wire I to the outside (no indexing), you will get 0 if the loop iterates 0 and 1 times. Not so nice... Felix
  5. Thanks for all that info so far, feel free to add more... One question: QUOTE (Dan DeFriese @ May 7 2009, 03:08 PM) Do I read correctly between the lines, that these tracking tools go further than just bug fixing? Felix
  6. QUOTE (PaulG. @ May 6 2009, 09:19 PM) I havn't tested, but if you can mimik the VI that passes all VI references (by loading a vi with the same name in the same context/namespace before the user launches the analyzer), and then you can filter. Just name the original file something else, and you don't loose the original functionality. Including it in your distribution will be illagal, but you can load a copy into memory, rename it, and discard it when done. As said, I can't promis that it works. I hav tried (unsucessfully) to hack the 'New...' dialog to get access to control templates (*.c
  7. Ok, now it's more going to be fun in hacking than real work (*). Some more specs on that point: - No SubVis, because it is the absolute easy hacker's trick to exploit the SubVi boundary in pre LV8 code. The Inlining VI (with some messing up and removing documentation) is already done, but not polished yet. - I want to inform the (informed) developer (via placed icon) that security Vi is in place. Furthermore, I'm pretty sure I can even fool VI analyzer, just by using the boundary trick and loading a Filter VI of the same name in the Analyzer context, that just skips the VI where that code

  9. QUOTE (i2dx @ Oct 1 2006, 09:26 AM) Nested Virtual machines on a computer cluster. So you have a dedicated sandbox for each beta testing software... Of course you should back up the feed by some SCC repository running as beta on a VM ... Ok, we are nerds, aren't we? I actually never tried LAVA with scotch and cigar, I prefer wine or beer and electronic beats... (Would be a nice poll to go for: whoch drinks do you like to be served with lava: Coffee/caffeine, Scotch/Alcohol, LAVA is addictive enough). Felix
  10. Here the idea: Code is placed inside structure (sequence or other); auto grow of; sized to Icon size VI is placed on top of structure to hide the code Both are grouped or locked, so moving the Vi don't reveal the code below. Problem 1: I can't size any structure small enough to fit behind a standard icon. Not even with private properties. Workaround: Place it behind an express VI (ha, finally found out what they are good for!). Problem 2: I can't lock or group the elements. A private property (write only) exists, though. I don't want to dig into (use) external nodes (I use LV 7!), bec

  12. Thanks, keep the posts comin'. I'm still missing the big guys.... As a general note: we as developers are pretty much free to go with any method we like, so to say I don't need a book to convince management to any method. But on the other hand, this means we software engineers will have to negotiate a 'common practice' among ourselfes. Always implying that someone isn't ok with it and any method will not be followed literally/in detail (one of the reasons to go with agile instead of formal methods). So I really need a book that is written for engineers that do a lot of LV programming (and ma
  13. I'm looking into some general aspects of software developement 'best practices'. So I would like to get some recommendations on books covering that topic which are useful for LV developers. We are already 'fluent' in LV, so we don't need (or have already) books on LV. But having pictures/drawings would be gentle for our minds and having cryptic C# class hierarchies would bore us to death. We don't have any formal method yet for our design process. A good overview of concepts would be nice to have to narrow down the choices. But also I will go a bit more into detail, so you could hopefully hin
  14. Got it working. It goes actually very nice as I can execute each plugin-exe on it's own as well as launching it as plugin. But I observed some strange behaviour of the plug-in's FP. Although set to 'top-level' (open front panel when called), it did not show up using the run method. I had to use the FP.Open property in the plugin vi. Thanks, Felix
  15. Cross-post from http://forums.ni.com/ni/board/message?boar...hread.id=405018 resonance wasn't to greate there. I'm planning an application with a plugin architecture, that will look up a directory during runtime for available plugins. I know I could do it using .llb Top-Level VIs. But I would prefere to have the plugins 'compiled', so as exe or dll. Is that a straight foreward build of those plugins or do we need to take care of some things? And how about compatibility when we use plugins of a newer LabVIEW version? Felix
  16. Thanks to all for your help. From the discussion so far, on the server side we can't work with encryption but rely on access permissions. The other points (https, client side encryption) are clear. We will discuss the issues today and I might come back with some more questions. Felix
  17. At first many thanks for your fast response on easter sunday. Our main issue is the security on the server side. Only those developers that are on a certain project should have access to the source code. And we would like not to completley relay on the OS permissions. QUOTE (Justin Goeres @ Apr 12 2009, 03:43 PM) Can you clarify that last sentence a bit? I understand it from a technical viewpoint, as the SVN keeps track of the changes in the directory structure and works incremental on binary level. But could not any one with a SVN client (given that the server is open to them) check out
  18. Until now, every developer has his code secured by using cryptographic containers (TrueCrypt). We now want to use the advantages of a small network including SCC (Subversion). What we could do, is check in/check out of the complete crypto-container. But that would not allow to have each single VI put under revision control individually. What other options do we have? We have not yet any experience with the SVN process, but are planning the network structure including folder structure of the central server. Is there any encryption support by SVN? Does passwort protected VIs work with SVN (us
