    Why, oh why didn't you take the blue pill? Do you see "GERONIMO" in your dreams? "Just because you're paranoid, don't mean they're not after you." - Kurt Kobain Album: Nevermind Song: Territorial Pissings
  2. dsaunders has pretty much written here what I've been thinking. I have nothing against GOOP. I've been using solely LCOD to this point and am trying to figure out if I should be using one or the other or a combination of both. I haven't had a chance to mess with GOOP too much to understand it completely. One of my things is that LCOD keeps me from having to wire up and maintain a crapload of refnums. I'm going to have to search around here and look at some posted examples of usage I guess.
  3. Thanks for your reply! So, you've essentially done a HD install of DSL, essentially making the filesystem writeable? That's where I run into problems. I guess I'd have to find a way to do a HD install, then create a new ISO image of that install.
  4. For those who don't know, LCOD stands for LabVIEW Component Oriented Design. Quite some time ago, I read the book: "A Software Engineering Approach to LabVIEW" (By Conway Watts), recommended reading to me by JohnRH before he left our company to become a mountain man. For those who don't know what LCOD is, it's essentially elaborate functional (LV2-style) globals that use an enum-controlled state-machine (commands... i.e. methods, property get/set commands) that can be used for data hiding and auto-initialization (1st call, invalid refnums, etc). In the book, it talks about LCOD and modu
  5. Oh, c'mon now. You mean to tell me that nobody in here has ever tried to run LabVIEW in a Knoppix-Based distribution?
  6. Has anybody in here ever run the LabVIEW developent environment on Damn Small Linux? I'm trying to do 2 things with this type of setup... not necessarily on the same machine. The reason I'm looking at DSL is because of it's ability to run completely in RAM. Now, if I'm doing LabVIEW development, I wouldn't be running in RAM. What I want to do is create an executable that will run in the DSL environment. This will give me the ability to boot a computer (with USB Booting ability) and start my application... unmount my media and the computer would still be running and running my software.
  7. I completely agree. A new install would save us a lot of time (and my company a lot of money for that time).
  8. UPDATE: After a few emails with SST, I got something working. Turns out that I was loading the wrong driver with the DLL, but the DLL isn't specified in any of the documentation. SST had to actually provide an example showing me which DLL to access. There's no way to have known otherwise, except with a good guess. That and the DLL is named appropriatetly: SSPBM32.dll None of the PBMMAN32.dll functions will work without that driver dll loaded.
  9. I was watching some show a month ago about tornado chasers and it showed a computer with a LabVIEW FP and an NI PXI setup.
  10. I've been trying to view/control the online status and configuration of a SST PBMS-5136 multislave profibus card using the "pbmman32.dll" and (decent)documentation provided by SST (Woodhead) with minimal success. The only function that I've been able to get to successfully execute is "PBM_Version", which returns the DLL version. Any other function, even the simplest ones return "FALSE" (error) when I try to run them. The other route I've tried with this card is via ActiveX. I've had better luck this way. I've been able to open a connection to the card, view it's online status and set
  11. I meant using DAQ hardware to control various circuits of lights and sync them to a song. The guy is a GE engineer I hear who got some module to synchronize various outputs to music. He did an awesome job. Apparently, his electric bill is $100 higher/month when he's running this setup (estimation based on last year's, where he did something similar with a little fewer lights).

  13. Check your VISA serial configuration VI (where you set up baud rate, etc). There should be a parameter where you can specify using the EOL character (windows it's <cr><lf>). When reading through serial connections, I believe LabVIEW's default configuration is to read until it reaches an end of line character, then it returns everything up to that character. If you disable the EOL character, it will return a specified number of characters instead of waiting until it receives the EOL character. I was going to fire up LabVIEW to check this to make sure I'm giving you accurate

    Thanks! He's not really (micro) managing, he's got absolute control! Especially when it comes to our sleep schedule, as is what normally happens. Both my wife and I have a new-found respect for our parents. They're coming down to help out today around the house. I'll be giving them really big hugs when they get here.

    Wow, I'm sorry that I seem to have taken over this thread (at least at the end) but just FYI, my wife had our baby early yesterday morning. First Name: Ethan Middle: James Weight: 6lbs 2oz. Length: 22" DOB: 9/18/2005 @ 11:22am Just thought you would like to know
  16. I have a couple of questions. Perhaps I misunderstood some of your instructions: You said to lock your central, resizable object. If I do this, the object will then not resize with the window. Did I miss something? Also, you said to anchor your panel to the origin (i.e. FP.Origin = 0,0). I've done this, but it seems that my resizable object "walks" down in vertical height each time the window is resized vertically. I should also mention that I have 2 objects I would like to be resizable. I grouped the 2 together before setting it as resizable. Would this be the cause for the behavi
  17. Thanks for releasing the secret Michael! I won't share it outside of LAVA so that only we are the magicians.
  18. I never noticed that option before. I always thought that you had to apply it to all items on the panel, except those that are locked. I noticed that some objects move with the window size, but don't scale with it. Is this done with a tricky combination of locks and scaling?
  19. I've been looking at the front panel for the OpenG commander for a little while this morning trying to figure out how Jim got certain controls to move, scale and even stay put when adjusting the size of the window. I checked to see if the "Scale objects with window size" box was checked in the VI properties, but it wasn't. How did you dood it Jim?
  20. Thanks for the pointer, I learned a few things, but unfortunately, this isn't what I'm looking for. I'm not looking to make my application THE executive. I would like to know the best way to launch TestStand and start the execution of a sequence file (possibly even login as well) FROM labview, not within labview. It's simpler than that even. The program I've created in LabVIEW is a test sequence browser. It allows a user to view revisions of sequence files stored in Visual Source Safe and select one to run. At startup, the LabVIEW program downloads the latest revisions of the supp
  21. I'm running LV7.1 and TS3.1. What I want to do is somewhat the opposite of how TestStand and LabVIEW were intended to interact I believe, since TestStand is intended to be the top level application calling LabVIEW. What I want to do is control the TestStand application from LabVIEW. More specifiaclly, open the application, display the window, open a teststand sequence file and start it. That's basically it, sounds simple enough doesn't it? I looked through the ActiveX APIs and couldn't find any clear-cut way of doing it. For example, when controlling MS Office, you can open the appli
  22. Thanks for the detailed information Michael. That helps me understand it more. To date, I think I've been using the DSC module waaaayyy below it's capabilities, but not having time to really get familiar with it has me using it in the way I've been able to initially get it to work. Using DataSocket will probably be the least efficient way for us to do what we want, but like you said, will be the cheapest and require far less time to implement than other solutions I've been looking at.
  23. We're going to be using quite a few tags I believe, so datasocket would be out. I forgot to mention. We're using profibus cards from a vendor that supplies both DDE and OPC servers to use with their cards. Is the OPC server from Kepware more "friendly" to use with LabVIEW?
  24. Is it possible? We're going to be developing a rather large application using multiple computers, all of which will have OPC servers running on them. Currently, we're using LabVIEW with the DSC module to access the OPC tags. DSC licenses are rather expensive, and cost is definitely a factor in our case. Does anybody know if there is a way to access OPC Server objects/tag values in LabVIEW without purchasing the DSC module? An option we're keeping in the back of our minds is using the OPCDAAuto.dll and essentially creating our own little version of it, but it requires time (of which we d

    Another update... It's a BOY! Had the 5 month ultrasound yesterday and found out. He's healthy, active, and camera-shy. He kept moving around where we couldn't see him, then just gave up and covered his face with his hand.
