LAVA 1.0 Content

What is the application is the more important question? Usually that will lead to better responses to how to accomplish something.

I am doing a minor protest that we should take down the LAVA facebook because it makes things confusing. I've gotten into the facebook thing and it is great!!! and way better than any of the other social networking sites out there. BUT LAVA is our social networking site and now if this takes off at all, I gotta keep tabs on 2 places to stay active in the community. I know there is little to no activity right now, but we alreay have a LAVA lounge, and if LAVA on facebook gets too active, it'll be hit or miss as to where conversations happen. Right now it's no problem. I just see impending doom.

One thing to add on, is that if you only show a subset of a very large list sometimes you don't want to update the entire data set as you scroll. Here is an alternative option that I have seen in some software packages. Instead of updating the table as you scroll, have a hovering tip strip or something of the like, that is linked to a column and displays what would be the topmost item if you stopped scrolling at that point. Sometimes row number is enough, sometimes something else makes more sense.

I remember hearing the statement that 'a class can contain nothing other than the immediate members of its class' in response to, why can't I put a child-class as a child under the tree and I believe that what you are trying to do violates that. But that being said, i agree that I should be able to put items as children in a class in a project tree.

You're explanation as to why you can't use it in a sub-panel is confusing. What happens if you try to run it in a subpanel?

We build Express VIs all the time here! When coupled w/ teststand, they are VERY handy!! We don't use them much if at all in our code though. What do you want to know about making them? It's actually very easy and very unlike creating Xnodes

QUOTE(Neville D @ Sep 7 2007, 01:03 PM) I was going to say the same thing. Use Array subset and only show a table on the screen as big as necessary. I recalled that MS Excel only allows upto 65536 rows but had to check; In Excel 2007 you can no have up to 1,048,576 rows; Ouch! Talk about repetitive stress injury and mouse miles! As far as the XControl; that might be a nice idea. I'm gonna play with an idea and see what I get...

A quick solution is not to re-open a reference to itself. The invoke node (not property node) FP.Close. when dropped into a Panel w/out any reference wired into itself will take the reference of the calling VI. Also when I run this, the re-entrant VI does not stay running. I would consider this an issue too, no?

Thanks! This statement is interesting; From http://www.killernic.com/support/faq.aspx#Q49 I'm not sure my customer (Uncle Sam) would commit to using this; but it looks good. Most TOE stuff requires a high-end server config (that I don't have).The dual-core (or quad, what the heck!) has been in my mind; I might be able to get my supplier to let me eval and check the performance difference.

Can you here him now? No? Good! We're doing our jobs! "It's the NOTwork." (jackboots and prostitutes posing as the Verizon Wireless "army" of engineers) So, there really is a worldwide plot to make Alfa miserable; the RCMP, the Romanian government, the universities, former yoga teachers and probably the children selling cookies door to door to raise funds for their camping trip. Wow. Really, wow. This thread is getting old, and I've got to stop reading it. Unfortunately it's like a car wreck; you can't help but look!

I am writing an array of singles to a postgres database table, with the column defined as a bytea. The bytea is suppose to be postgres's blob datatype, I do not get any errors writing or reading the data. The problem is that everything after the 63 value (255 bytes) is junk. I can not find a logical explanation for this, and I can not see anything wrong with the method I am using. I have attached an example that exhibits the problem, if somebody has time to create a table in postgres or another database and try this, it may help determine where the problem lies. Also, if anybody has any idea what is going on I would appreciate the help. Thanks in advance, I kinda discovered the problem late, and I am under the gun now.

I've been slowly adding higher and higher data rates to my multichannel UDP receiver and have pegged the CPU (95-100% while streaming). The effective rate is 3 channels * 4800 messages/sec * 512 bytes/message or ~ 59 Mb/s. I'm looking to free up some cycles for additional features. I recalled reading some time ago about smart NICs that offload some of the TCP processing from the CPU, so I started Googling. The proper term seems to be TCP Offload Engine (TOE). No fetish jokes or links to "inapropriate for work" sites please Anyone have experience with TOE? So far I've only found PCI-X NICs and references to 64 bit Windows; I'm more interested in a PCI / XP Pro solution. I can't change out my processor or backplane at this time; I'm using a P4 3.0 GHz, 2 GB RAM and in a rackmount PC with passive backplane (PCI only).

Nancy, Good idea.. Next time you're in town, we'll take you to a ... well... not so secret place..., with LOTs of beer! :beer:

What is it called? Modulo? No. Quotient and Remainder. Xor? No. Not Exclusive Or. I'll stick with the icons... As long as we agree to leave the friggin' palettes alone!

Not directly related to Aristos' challenge, but wanted to share a BLOG I read that contains quite a few entries related to graph theory: Amortized Complexity - a Tool for Graph Algorithms (among others) Graph Theory The first link is the latest in a series of computational complexity posts that seem appropriate to the discussion... Happy reading EDIT: Also, this post on sorting Not Quite Basics: Sorting Algorithms

Hello, Here is the function you are looking for : http://forums.lavag.org/index.php?act=attach&type=post&id=6849 http://forums.lavag.org/index.php?act=attach&type=post&id=6848

Interesting, but can you tell us how it relates to LabVIEW? A search of "labview" on your web site returns nothing. The info for the Taiko OS indicates that the device supports 32 bit registers and multidimesional arrays; will this device be usable as a LabVIEW Embedded target?

[Esc]:wq!

Now I know for a fact that at some point in time in the past, at at least 7.0, NI themselves released a small package that would allow you to interface with the notifier/system tray. I know this because I downloaded it and it had the NI logo on it and came from an NI person. Now whether this is the CVI one that I have seen on the NI forums I am unsure because I have yet to download it and my backup drive did not show that anything like it was available. And on top of that there was one also released for free at at least the time of 7.0 that came from a 3 letter acronym company like SVT or STV or SFT or ... well heck I can't get it otherwise I would have found it by now. Gotta run for now, but does anyone remember this to prove that the bathroom chemicals did not permanently damage my memory.

QUOTE(Ben @ Aug 20 2007, 02:02 PM) Any basis to your theory based on the poll so far? Roughly 25% seems to be above average...

QUOTE(MikaelH @ Aug 30 2007, 09:06 PM) It shows you help lines when you reached edges of other objects like this picture. I like this idea. It reminds of of witness lines (I'm an old time CAD guy). It would be nice if we could turn something like this on and off; sort of like "show coersion dots" :thumbup: I wonder if anyone at NI has looked at reusing UI functionality between the Multisim/Ultiboard products and LabVIEW. I'm not familiar with Multisim/Ultiboard; but features like radial grids and auto-alignment and spreadsheet view make me wonder and even drool. Imagine being able to see all of your controls in a spreadsheet, sorting/filtering them by type, then changing properties en masse, then applying the changes to the FP. I've got to get into marketing...

I experimented a while back with using a customer's Matlab scripts in a node; the main problem was extracting all the UI related commands. I was told by my NI rep that I should keep the number of lines to between 20 and 100 for performance purposes; if there are more than that I was told to break the logic into parts and pass data between the nodes using LabVIEW wires. Good luck!

Did y'all ever decide on a purchase

I'll throw my hat in the ring with a neat util that I got some asstance from G Zou getting together. Only works on windows but doens't use any API calls. It allows you to have multiple items in the drop down list using the standard LV file dialog. It demo's well simply by placing on a blank BD and running it. You'll see the below dialog http://forums.lavag.org/index.php?act=attach&type=post&id=6798 Enjoy http://forums.lavag.org/index.php?act=attach&type=post&id=6799

Confirmed here too, happens on 8.0, 8.20 and 8.5. I checked VISA Serial Break in these versions and saw the 'regular' behavior for the property nodes. LV versions 6.1, 7.0 and 7.1 do not appear to have this 'irregular' behavior. Might this have something to do with la mort du Serpdrv?
