  1. Hey Randy- did you manage to figure out a solution? or did you end up changing your code? I just ran into this issue yesterday and have been stuck since, Error 1498 occurred at Get LV Class Default Value.vi Thanks for any info/ideas -pat
  2. My senior just pointed out my mistake- I'm dropping child methods instead of parent methods ... the VI icon for this particular case was edited in the child method but not the parent- so when I dropped the child it magically replaced it with the parent... whoops. thx for the quick reply too! -pat
  3. You mean an event structure that executes a frame based on an AND result of a [bool value change] and a [mouse down event]? -pat
  4. Hey folks, I was wondering why my subVIs icon changes from the one I made (that says 'close' on it) when I wire the class to it- it turns into a blank VI icon from that class with a number 2 in the bottom right. The VI works, and it is definitely calling the right VI, but I just wanted to know why the icon changes. Thanks for any info! -Pat
  5. Sry for gettin off topic here, but Shaun- noobie question, is there a way to set up your structures to have color tint like the for loops ya just posted by default? So every time I lay a for loop its tinted yellow, while loops blue etc etc... and also- if I did this, would it stick with the vi if I were to send the vi to someone or edit it on another computer? thx! -pat
  6. I just bought a 13 button mouse (G700)... not only does it have buttons for days, but you can program one of them to change back and forth through 3 different "profiles" so that all the 12 other buttons can be config'd for another 12 hotkeys and or macros... with timing recorded on the keys too... it's a wee bit overwhelming lol... somehow, despite having the button "unassigned" in logitechs mouse config sw, when I hit one of the buttons it Ctrl+E's by default... kinda handy haha. we'll see if I can actually put these buttons to some productive use... It's a wireless guy that apparently w
  7. Do you mean wrecked your productivity while trying to write code without the mouse shortcuts? thx for the responses -pat
  8. How do you edit a post you made? I don't see an edit button... anywho... Assuming that you can make your own hotkeys and such, it'd be cool to use something like this even though it is overkill http://www.amazon.com/Logitech-G13-Programmable-Gameboard-Display/dp/B001NEK2GE/ref=pd_sim_e2 take your most commonly used commands and map em to the keys and whatnot... -pat
  9. Hey- I'm looking to buy a new mouse (the one I have keeps randomly reseting its position to the upper rightmost spot on my displays) and looking on newegg I see mic with upwards of 10+ buttons... My question is, have any or many of you set up any of the extra buttons on your mouse to execute shortcuts in labview? Are there a lot of programmable shortcuts or hotkeys in labview that make you significantly faster? I'm aware of only a few with the quickdrop window, so I suppose if you could get one button on the mouse to ctrl+space and another to ctrl+d (or whichever). I think I read or heard
  10. Thanks a lot for the info! I'll take a good read of the help pages next time -pat
  11. I certainly consider myself a noobie here and with LV, my coworker just showed me how he uses the disable structure- I think it will prove to be useful for me in the future. I wanted to ask a question though- if you tell LV to build an EXE from VI, and the disable structure has some code disabled, is any of that disabled code compiled into the exe? or just left out? thx for any info -pat
  12. Hey folks, quick question- Im wondering why the USB 6525 isnt available in MAX as a simulated USB device, and if there's anything to do to make it available. Suppose I could use a simulated USB 6501 as a stand in for simulation functionality right? anyone have any other ideas? Thanks -pat Errrr... scratch that, doesn't look like 6501 is available either but I see no reason not to use PCI or PXI as long as the outputs are the just regular DIO... -pat is there a way to delete a post?
  13. I just burnt my pop tarts.

  14. No, the XPe piece is running a LV executable that utilizes a USB based DAQ amoungst other things, I'm really just looking to use a USB cable for serial communications just like a 232 hookup so that the system can be just as versatile as a common Test & Measurement class USB device. (partially because rs232 is kind of on its way out with many computers sold without the serial DB9 ports.) -pat
  15. Hey folks- I reckon my question is more windows XPe related than LabVIEW related, but it wouldn't surprise me if someone here has dealt with, or considered this idea before in this arena. My googling has turned up very little... but I want to know how feasible it may be to turn a box running XPe into a USB device (test and measurement class) that can be recognized by a remote hosting computer - all the while still being able to host USB devices on other USB ports itself for USB DAQ. Even if someone was willing to point me in the right direction, to documentation or another forum it would
  16. Hello I'm working with eval versions here, but my employer's about to purchase the appropriate lic's. I just wanted to show them what it is I intend to do- anywho, onto the problem... Vision assistant's thresholding function under the grayscale tab doesn't seem to let me select just an ROI to analyze- quite a simple issue that I feel dumb asking about but it was particularly simpler to do in vision builder... it simply thresholds the whole image, and that's it. Anyone have any experience with this? or think I'm just doing something wrong? Thanks -Pat
  17. QUOTE (jdunham @ May 18 2009, 11:28 AM) Ah, I see (said the blind man), so I don't even need the controls editor... I guess that was a poor assumption. Dan- I will try and get the indicator done and post it up to at least show you guys what I'm after- right now I'm trying to fogire out the sizing of the gifs and the ring control... thanks much guys -Pat
  18. Hello- I'm struggling quite a bit despite the documentation I've found here (http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/custom_cont_ind_type/). Everytime I open up a new control or go to Advanced>>Customize from a Picture Ring, I can't seem to get the behavior of the picture ring right- It makes me wonder if I even Understand the way the picture ring is supposed to work. Either way, this is what I'm trying to do: I'm making a system that uses vision to interpret the position of a dial (one that is manually adjusted by hand when in use). And although I have the vi
  19. hmmmm.... she doesnt seem to be working... either that or I'm totally missing something (not unlikley). The bottom (calculation) loop seems to get started too early, then it acts like it comes to a halt, and changing the ms wait value doesnt seem to influence the result... I feel like theres something real dumb im missing.... maybe I'll get later or something. I spoke to a buddy of mine here who's a grad student, turns out he's working on something really similar, and actually handed me some matlab code for taking IMU data and extracting low-noise info. it's basically numerical integrati
  20. QUOTE(LV Punk @ Aug 29 2007, 07:26 AM) wow. thanks! unfortunetly my partner has the IMU right now but as soon as I get it in my hands I will be sure to run it and see how much quicker it is. - I guess my noob-status still stands, I'm still interpreting the changes you made haha, I've never actually used anything off the que pallette. thanks a lot for the help, I really do appreciate it, unfortunetly I don't know of anyone here that really knows labview this well... I'll let you guys know how it tirns out! -pat
  21. QUOTE(Neville D @ Aug 27 2007, 01:04 PM) thanks for the advice, it is much appreciated. I tried the non-express integration but I must have been using it wrong, despite reading the help file cause I kept getting all zeros. The dissapointing part is that the computer Im trying to do this on isnt exactly a workhorse either. I'm finishing up a computer I'm building that will hopefully give me a lil better results, I suspect having more than half a gig or ram would help no? time will tell I guess... thanks again for the help -pat
  22. QUOTE(tcplomp @ Aug 25 2007, 03:43 PM) haha oh man, I didn't even see that! thanks for pointing it out, 200Hz.... lol the 14/18 bytes idea.... what about the spaces? I might be wrong because the program seems to jump out of synchronization and starts chopping up the packets, trying to read them after cutting them in half and it doesnt recover either... I'm not at school at the moment, but I'll take a gander at it again as soon as I get in. thanks a lot for the help! it's much appreciated. -pat
  23. Ok, here's the deal so far: I have a sparkfun IMU that spitting out XYZ accelerometer info over a serial connection @ 57600 baud. I have it hooked up to the COM1 port and in general, it works (drops out though after a lil bit, but thats another problem!) my problem that seems like a doozie to me is the display of the data. I want a 3d display and I have that, it looks and functions beautifully excluding it's ssslllooottthhhh like nature. of course I guess it could be the activeX stuff thats hogging resources or maybe its the time domain integration im trying to do on the data... my buddy
