Hello everyone, I am working on putting together a test executive that pulls from a lot of external code libraries. I'm at the point now that I have a fair number of custom error codes generated by different DAQ libraries and keeping track of all of them is becoming increasingly difficult. I've been using error rings for custom error generation and while not ideal has served well enough until now. Keeping track of the codes hasn't been hard because they are few and far between. I've been thinking about transitioning to a custom error file instead of using ring constants because keeping track of it all is not realistic anymore. My question arises from the fact there are ~10 different libraries in this current project all pulling from 3-4 different source control locations and creating a single error file that covers all the errors from these libraries seems incorrect. I would think custom error records would travel with the library that uses them, but does this create file reference headaches when you start pulling in libraries and external references, PPLs, etc? Question: How do you keep track of your custom error codes? Some options that I could see being viable: A single company wide error code file that gets pulled down with your version control. A blanket approach would make sense and also would prevent error code conflicts from one library to another by forcing communication during modification and addition. Error code files packaged with each individual library and pull them all into projects when they are getting developed. This seems the most modular and portable but could result in conflicts with error code numbers if developers don't communicate about the ranges they are using; also how does LabVIEW do with referencing lots of different error files. Cheers, Tim

I've been using Labview for 6 years now for research and one of the most confusing things for me is how code is supposed to be managed. I have been using Tortoise SVN with folder organization but with things getting more complicated I am starting to wonder what the "right" way of doings things is. I've looked through a variety of posts and official documentation and haven't found what I am looking for (or haven't realized it was what I needed). I'm using LV2009 32 bit, JKI TotoiseSVN Tool 2.2.0.186 (demo), Tortoise SVN 1.7.6, Win 7 x64, and have little interest in actual code deployment. Features I am looking for: - avoiding cross linking problems - prompts to save a vi only when it has been changed - svn integration - code that works with multiple developers instead of corrupted files (mainly thinking about project files) My code base consists of project or modules (not lvproj) just a set of code in a directory & subdirectories. When I am running a program, many of these modules will run together and collect data, with a messaging system in between where necessary. In addition I have generic code libraries (not lvlib), with generic functions (math, string, table, server, etc). It seems like my code libraries should be lvlib files. After some reading it seems like Project Libraries can be used for preventing namespace collisions. On a side note the term Labview Project Libraries is very confusing because I think of Labview Project Explorer which I have no gathered does nothing for changing the namespace. I did happen to find this link, which helped get me started but I'm still not understanding some things. As a general rule I pretty much want library membership to always apply to files that are in my libraries directory, which doesn't seem possible. Question 1: How do I delete a library file via SVN and remove it from the project. I am using the JKI TSVN toolbox and removal of the file doesn't seem to effect removal from the library. Question 2: If I create a vi and later decide to move it into the library, how do I accomplish this in Labview with SVN tracking. For example, if I create a vi in one of my modules and realize that it is fairly generic and would be better in a library, how do I move it to the library (ideally on disk and into the library file) so that both Labview and SVN are happy. Another situation might be moving a file from one module to another module, ideally I could move both library association and disk location. Question 3: If I am running multiple modules, how do I ensure that they have no namespace collisions? Should these be libraries as well? Do I only need a project if I want to deploy my code? Question 4: When someone creates a vi outside of the library but in the library directory how can this be detected and fixed? Question 5: Is there any way to get better svn integration into the lvlib and lbproj right click menu? My current approach would be to do this through the tools menu (tools -> TortoiseSVN -> rename). Side note, this doesn't doesn't currently work on my computer although the actual TortoiseSVN through Windows Explorer works just fine. Question 6: My files are constantly prompting for saving. It seems like most of these are changes from other files and not the file I changed. Since I don't know really know how this works I am not sure what exactly is going on. The end result though is that I want to minimize version changes (as tracked through SVN). I seem to remember reading somewhere that in LV2010 you can separate source code and compiled code. Thoughts? Would this be fixed by better lvlib and lvproj usage or is something else going on? Thanks, Jim
