  1. Hello fellow LabVIEW wirers, I am "renovating" a relatively large program I have made in the past with new features. I am adding alot of buttons in the process, which I plan to control with event cases. Some buttons lie directly on the front panel, while some are in a tabbed interface (a few buttons for each tab). On the block diagram, I have an event structure surrounding the case structure (for event timeout=100ms) which handles events for the buttons outside the tab. The case structure is for the tabbed interface. I am thinking of either placing a set of nested event structures (for e
  2. Yep.. after adding stuff to the .ini I was able to edit the actual plot bounds. Thanks everyone for your help!
  3. Hello once again, I am having trouble coding a way for the user to control the "plot area" size (which I interpreted as the black gridded area) without changing the overall size of the graph. My reasoning is in regards to aesthetics; I don't want a gap between the graph and a decoration. If this cannot be fixed, is it possible to programmatically control the size of a decoration? I doubt it myself because there are no block-diagram components for decorations. I have attached a sample VI to further illustrate my intentions. Yes the outcome is not significant in importance but I have a pet
  4. Hello one and all (again), Is there a way for the user to save the state of one's program (i.e. the values of a control) to a file without manually writing values to a spreadsheet manually? It would be kinda useful in the event that a buncha settings are tweaked and the user just wants to quickly recall them later. Muchos gracias, Mayur PS: please do not be offended by my post icon, I wont use it again!

    That movie was the s*** - I mean the best ever :thumbup:
  6. Very clever "underlying truth" :thumbup: in your time reversal algorithm Hope my comments are slightly more lucid than those of al.... allright time to get back to work :ninja:
  7. Hello one and all, I am trying to solve for a root using Find All Zeros of F(x).vi (Functions>Analyze>Mathematics>Zeros), but I am getting an answer that is out of my specified bounds (see attachment). I could probably check for this in my program, but why isn't this function detecting this? Thanks, --Mayur P.S.: O'yea I already tried using a different algorithm and different step type, but the answer was the same. I go a root at x=.69 even though my start bound limit was .73. Oh and I am using Labview 7.1 in this instance.
  8. That's horrible :thumbdown: . That is why I am a vegetarian :thumbup:

  10. If removing overlap and increasing times between refresh do not fully recover CPU speed, try investing in a graphics card. GCs almost always have a separate processor and memory dedicated to graphic alone. As a result, you main processor and RAM will be reserved for computational calculations, and the graphics card's processor and memory will deal with graphics. Mid-range cards usually run for around $100; however, you may find a decent lower-range card that fits your application for much less. I suggest buying a card that has at least 64MB memory and a core clock speed of 175MHz. This ma
  11. Hello one and all, The current project I am working with requires a UV lamp that emits a very focused and narrow beam of UV light. The diameter of the beam should be within one micron or, if possible, adjustable between 1 micron and 250 nanometers. It must be focused enough to emit this diameter of light when fixed above the specimen 10 cm above. The wavelength of the beam is not a concern yet. Any help or ideas are appreciated. Regards, Mayur
  12. Nice! :thumbup: The only problem I have (a very minor one at that) is that the point where drawing occurs is above and slightly to the right of the cursor (see picture).
  13. Yeah, I should of done that, but all you needed was kel's code, since I used those subvi's. No worries, i'll just provide the lib. Download File:post-2549-1124897010.llb
  14. Ok, sorry about that... my last post's attachments were not in this format, though, because they were only two files.
  15. Yeah, I forgot about using libraries... duh! I'll be sure to use them in the future. Thanks
  16. Sorry I couldnt ZIP it, my work firewall filters uploaded zipz

  18. Well, I already use about 10 subVI's (which are called multiple times) and plan to use more. I do have to agree though that many of my core calculations and functions are done in the main. I did this because I programmed the basics of the program first in the main and later became too lazy to change it afterwards :headbang: .
  19. Ok, here's what I want to do: I want to enable user drawing on a graph (similar to examples > general > uievents.llb > Draw Graph with Events.vi), but the graph I have has two plots. I only want to allow drawing on one plot. The problem with the Draw Graph example is that it only supports one plot graphs. In addition, having used LabVIEW for just two months, I am not too familiar with event structures and references. Moreover, it seems I cannot modify the example to be a subvi without having to rely on shift registers (I require the while loop to be in the main and the event subvi
  20. Hey all, I have a VERY newbish question today :thumbdown: , and I am pretty sure the answer is no, but just in case: Is it possible to use event structures in subVIs such that they handle events of the main program? I know it's very likely this is not possible since it is out of scope of the main, but I am not 100% sure about it. I would find it REALLY useful to implement event handling in subVIs, as my main is already very large as it is.
  21. LabVIEW should integrate this into their comparisons when dealing with floating-point numbers...I don't see the use of preserving traditional exact comparison in this circumstance (even when comparing two different numerics, since one is casted to the other's type anyway). Maybe when LabVIEW 8 comes out :clock:
