  1. QUOTE (Dan Press @ Jul 9 2008, 11:12 AM) excellent, thank you
  2. Hello. I need to make a combo box that will check a user specified directory for its contents and then put all of the file names into the combo box as choices. Unfortunately I have no idea where to start with this. Any help would be greatly appreciated. Thanks, Pat
  3. Hello, I've been trying to get a SRS sim970 quad digital voltmeter to read out the voltage from one channel using a GPIB interface with the sim900 mainframe the sim970 is in. I have gotten the correct voltage, but the output is extremely inconsistent. The display on the meter always reads correctly, so I think I'm having issues with how the data is being read from the sim970. I'm using all GPIB reads and writes using the following commands: - write [sNDT 2, "VOLT? 1"] - write [GETN? 2,100] - read 100 bytes Any ideas/suggestions? Thanks.

  5. QUOTE (Aristos Queue @ Mar 17 2007, 05:37 PM) Hi, I don't quite understand how this is initialized. I have it within a if block that will only execute once every few minutes. How do I ensure that it gets initialized when the program begins? -Pat
  6. QUOTE (Phil Duncan @ Jun 18 2008, 02:51 AM) Thanks for the help. Why is it that a control/indicator won't name the data in my program? I'm having a very hard time visualizing and understanding what labview does with it's data and how you manipulate it.
  7. I've got my program working 95% with the help of those in the lab I work in and finding vi's here (you may recognize the boxcar algorithm, thanks to whoever it was that posted that). However, I cannot figure out how to change some of the labels in the text file that my program is outputting. I would like to change the units and the column descriptions for each column of data in the output file. The vi was generated using labview 8.5 professional development system.
  8. I've been using labview for about a week now and have found several useful posts here, but now need to begin asking questions. About me: I'm a physics major doing a summer research program that requires labview programing.
