  1. QUOTE (freemason @ Jan 16 2009, 03:18 PM) You're welcome. Keep coming back!QUOTE I was close, I wish I knew how to do it. Were you able to figure out what I did, or do you still have questions?
  2. QUOTE (gareth123 @ Jan 18 2009, 01:37 AM) You didn't wire anything into the graph Your formula only makes one data point; I think you need a chart instead Your formula calculates to a constant Try this one
  3. NI says that a CLD: QUOTE Passing the CLD exam doesn't prove that you fit this description, but it sure does make people think that. It's a bit of misrepresentation to present yourself as a CLD without having the ability to back it up.I passed the CLD exam with less than one year of experience. When I left my first LabVIEW position, my new employer knew only that I was a CLD (and that I interview well enough) and hired me. The pressure to produce at the level they expect is high; I've worked a lot of hours and still look back and shake my head at some of the programs I've written! I expect to always keep learning, but at some point my basic approach has improved and my code is cleaner. I think that this is what is expected of a CLD. I've toyed with the idea of sitting for the CLA exam. I doubt that I'd pass it the first time, but I'd sure learn the test. I'm good at passing tests and would probably pass the second time, but then I'd be misrepresenting myself. A CLA: QUOTE Demonstrates mastery in architecting LabVIEW applications for a multi-developer environment Demonstrates technical expertise and software development experience to architect LabVIEW components Manages projects by effectively utilizing project and configuration management tools Possesses experience of approximately 24 months in developing medium to large LabVIEW applications Good luck with your career, but know that a LabVIEW job interview might contain a test! This has been discussed on this forum here, and other places. EDIT - Oh, yeah. I've begun working with the OpenG project in an effort to learn more of the "architect" and team-oriented development stuff that is expected of a CLA. I expect this will be a mutually beneficial relationship in that I'll grow as a developer and, in exchange, I'll work on Open Source software that many of us use. Talk about a win-win situation! I've also thought of working on something for the Code Repository (may still do that). These are options for you, too, to help you gain the experience you need to go along with certification you want.

  5. QUOTE (jcarmody @ Jan 16 2009, 04:52 PM) Silly me, I didn't wire the error cluster into the Shift Register.
  6. I've managed this. It deleted 100 files in only a few seconds (and put them in the Recycle Bin).
  7. This deletes files but doesn't send them to the Recycle Bin. Any ideas of how to get them there? I'm thinking .NET, but I've never dot-netted anything.
  8. Here's your code, slightly modified. You were so close! I added a delay (to stop hogging the CPU) I added a Case Structure and a Shift Register (to control when the 30 second timer operates) I deleted your wire between Get Start Time and Set Start Time I changed the Boolean control to a constant to Auto Reset the first timer I added a First Call to the test so you'd get your measurement at T=0 You'll also need to multiply your "at every" control by 3600 to get the first timer to run for hours instead of seconds.

  10. QUOTE (zmarcoz @ Jan 15 2009, 03:52 PM) The pictured VI is fine because the two loops aren't trying to run in parallel. The first loop is building an array of random numbers and the second loop simply indexes through that array, increments each element and displays it on the Front Panel (although, it'll be too fast to see). This wouldn't work if you wanted to display the incremented value in the second loop while the first loop was still running. (BTW, you'd be better off using a For Loop instead of the second While Loop; it'll auto-index the array and you don't need to worry about the loop conditional terminal.) http://zone.ni.com/reference/en-XX/help/371361E-01/lvconcepts/block_diagram_data_flow/' target="_blank">This is data flow. I don't know QUOTE the meaning of communicating between while loop(case structure) </jim>

  14. QUOTE (mross @ Jan 15 2009, 11:46 AM) This looks like a follow-up to http://forums.lavag.org/-t12864.html&view=findpost&p=56729' target="_blank">this post. zmarcoz, you were asked to post a picture of what you were asking. That'll get you your answer. It looks to me like you mistakenly wrote "case structures" instead of "while loops" here. QUOTE B you cannot use wires to pass data between case structures. <=== My choice, but not sure is correct I recall a question that had a wire from the stop button in one while loop going to the conditional terminal in a second while loop. The problem with this architecture is that the second loop won't start until the first loop is stopped (with the button), then it will only loop one time because the stop button sent a True. Of course, I'm only guessing BECAUSE YOU DIDN'T POST YOUR CODE/PICTURE. You're running out of time! Good luck tomorrow. :thumbup: </jim> PS - Hi, mross. I'm in Wilson, NC, too!

  22. I saw the Denzel Washington movie Deja Vu this weekend and (except for one unnecessary scene) thought it was the best movie I'd seen in a long time. Did anyone else catch the SNL reference when they were sending the note back in time? "I need more cowbell!" That was great! </jim> "Guess what?! I've got a fever, and the only prescription... is more cowbell!"
  23. QUOTE (zmarcoz @ Jan 14 2009, 12:31 AM) You should take advantage of the option to mark a question for review. I did this when I took the test a few years ago and was pleased with that feature of the testing system. It turned out that I had to mark most of them the first time through because I wasn't confident with my answer. I kept going through the test until I had unmarked all of them, then I submitted my test and found I had passed. Good luck! </jim>
  24. QUOTE (mic_k86 @ Jan 12 2009, 01:20 AM) Will this do, of have I missed something? The user can select the time interval and this will control the loop rate. Jim PS - your VI is missing error handling... PPS -
