  1. Here's a heads-up for any LabVIEW developers in Central Texas, or any Certified LabVIEW Architects coming to Austin for the CLA Summit next month. I will be teaching Actor-Oriented Design in LabVIEW, Sept. 13th - 15th, in the training center at NI's corporate headquarters. Come take the class, enjoy Austin for the weekend, and stay over for the Summit! Details on the course offering here: Actor-Oriented Design in LabVIEW There are offerings in October as well, in MI, MA, and Santa Clara, if those locations are more convenient.
  2. I miss the ribs. Any chance we can get some this year?
  3. For a circular buffer like this, you can convert the functional global into an actor. The actor's private data would be the data stored by your functional global (anything in a shift register), and it would have one public method for each operation the global supports (write data, read last, etc). You will provide a message for each of these methods, of course. To use this buffer, launch the actor and pass its queue to whoever needs to access it. The net effect will be very much like putting your original functional global into a DVR, with no deadlock/race condition concerns.
  4. Greetings! I am a Certified LabVIEW Architect with 16 years experience developing innovative LabVIEW and TestStand solutions. I am currently seeking short- or long-term projects or employment in Central Texas. Most recently, I was the architect for a systems integration team at a large engineering services firm in Albuquerque, NM. I served as the architect and/or technical lead on several mid-sized to large projects, on project teams consisting of one or more LabVIEW developers, an electrical engineer, and several technicians. Most of my projects have been for Sandia National Laboratories.
  5. Greetings, all! This is pretty self-explanatory. I need a LabVIEW implementation of the SHA256 hash algorithm. I could do it myself, but I was hoping one already exists. Has anyone written such a beast? Thanks!
  6. Greetings, all! I have a client that wants to use a piece of LabVIEW code on Windows XP, Vista, and 7. The application was originally written to run on XP machines, so everything looks OK there. However, on Vista or 7, certain front panel objects appear larger than they do on the XP machine (in one example, all of the string fields in an array of strings are taller). Other objects (such as a text label) appear smaller. The machines in question all appear to have comparable DPI settings, and monitor resolution does not seem to be a factor. The application uses Application Font in various
  7. Greetings, all. I want to be able to display the version number of a built executable in an about box. Is there any way to programmatically get this information? Thanks!
  8. Greetings, all, I need to call a DLL in the Windows API. The DLL returns a pointer to an array; the array is a list of process identifiers (strings, I presume). What do I need to do with that pointer to get an array of strings? Thanks!
  9. QUOTE (Darren @ Feb 12 2009, 10:24 AM) True. But the requirements for the toy problem do lend themselves to a class-based design. Even without LabVIEW Classes, applying OO techniques on the test goes a long way toward submitting a clean design. Not required, but very, very helpful. edit to complete thought: So my point to the OP was that demonstrating one's ability to deliver a good class-based design fits better with the CLA than in the CLD. QUOTE (Aristos Queue @ Feb 2 2009, 06:08 PM) Others are welcome to try their own puns, but I should warn you... the only other word in English
  10. QUOTE (Aristos Queue @ Feb 2 2009, 06:08 PM) The CLD tests if you can design and implement a state machine. The CLA tests if you can design classes. <shrug> I'm actually pretty OK with drawing the lines like that. Even with classes, we still do a lot of our work with some form of producer/consumer pattern, usually including a state machine. Someone who has passed the CLD has shown that they are comfortable actually working in the LabVIEW environment with our bread-and-butter tools. I can give that person the design for a class and expect it will get coded, even if that person is
  11. QUOTE (jzoller @ Feb 3 2009, 09:42 PM) I recall having a conversation with an NI person at NI Week some years back. This fellow told me that, in large part, this is exactly why NI markets almost exclusively to the "no programming" crowd - it keeps LabVIEW under Microsoft's radar. NI did not want to get into a shooting war with Microsoft the way that Netscape did over browsers. MS has very deep pockets and could take a loss on a new programming tool for years - long enough to successfully undercut NI's LabVIEW sales. NI may be a hardware company, but LabVIEW sells a lot of that hardware
  12. QUOTE (crelf @ Jan 29 2009, 05:30 PM) Oh, OK. Is there a "scripting toolkit" now, or something similar? Does it ship with any of the developer suite DVDs?
  13. Greetings, all, I am finally starting to look at scripting in LabVIEW. I have downloaded the scripting tools and the package that shows the new VI and New VI Object primitives. I have also added these entries to my INI file: SuperPrivateScriptingFeatureVisible=True SuperSecretPrivateSpecialStuff=True I can access a lot of things that I couldn't before, but I still have trouble getting to most block diagram item properties and methods. I cannot, for example, create a block diagram constant for a "Function" reference. If I look at a property or method node in an example that is working w
