Ha! Have you created a dynamic model (using LabVIEW) to evaluate the efficiency of this? It should be easy, considering that 8-10 year olds have developed a real-time measurement system to model and test the flow of their sewer system!

(I love NI & April Fools Day; 10+ years and counting!)

Hi ,I am experiencing a problem with QT Java 6.1 on Windows XP using Java1.4.2 (_2, _3, and _4) where a QT Component (as Component()) created from a Movie Controller placed in a window or frame will sometimes freeze when another window is placed in front of it or removed with set Visible(true/false). I cannot produce a test case or anything of the like because I cannot reliably reproduce it on command. The freezeoccurs on the set Visible () command. Looks like some DEADLOCK. Has anyone else experienced this?
Any suggestions? Ideas ? Thanks.
I see this is your first post to LAVA. Can you tell us how your problem is related to LabVIEW?
LAVA stands for LabVIEW Advanced Vitual Architects. Maybe you are looking for help with JAVA?

And as a seperate comment, I have to say that while I'm happy that NI has gone to such lengths to optimize this stuff under the hood, it seems like a lot of work for little gain in terms of speed\memory usage. As far as I know, the output of any array native that produces a sub-array (i.e., AQ's "stride "array) either goes to another array native, a non-array native, a subVI, or a terminal. If the sub-array goes to anything other than the first in that list, LV has to automatically allocate a full array before proceeding, which wipes out any gain in efficiency.What happens to array data passed to a sub-vi might have an impact on the way the the http://forums.openg.org/index.php?s=&showtopic=820&view=findpost&p=2100' rel='nofollow' target="_blank">Average 1D Array (Candidate) develops.
I don't want to hijack or move this dicsussion to the OpenG forum, but anyone with some input that will enlighten us (OK just me) would be appreciated.

In the post crelf referenced, there are many entries above and below. To reply without quoting, you need to scroll to the top or bottom of the set to select 'Reply'. It's easier to reply where you are reading than to scroll up/down. I've always used the
and then immediately delete all the text (unless I want to "quote someone" like crelf
). The 'tip' for the
.
button indicates that the reply is to that specific entry I think replying to a specific post has value when using the threaded mode, but that hasn't worked so well and is essentially disabled (although threaded mode does show up now and then on my home computer).
Maybe placing a
in front of the
and
buttons would reduce the "noise". I don't really use or see the value of the
button. -
The real question for me is "Can he code LabVIEW?"

Go for it! I've liked the term for some time and make a distinction between it and it's cousins (LV2 global, functional global) in the wiki. I tried, but don't have the stomach or time to argue if such a term is "http://forums.lavag.org/index.php?showtopic=9833&view=findpost&p=40276' target="_blank">contrived". I was pissed for a few days and almost didn't renew my LAVA membership; then realized its not that important. I have decided that I'm no longer a wiki contributor though...
It's amazing how powerful words are, especially when they are used to describe something graphical. If a picture is worth a thousand words, I've "VIagrammed" the equivalent of "War and Peace" at least once.
- "VIagram" - a LabVIEW block diagram image
- "VIagramming" - the act of creating a LabVIEW diagram image
It also contains the string 'viagra' which should help it's acceptance and Google ranking.
"Thanks for the example VIagram, dude; it kept me up for hours, but now my program is solid and runs for days without crashing!"

Yikes! I made an image in case NI deletes this "Colonel Mustard" (first post) entry.

I don't have a direct answer, but did you look at this post from a few weeks ago that includes a "Terminal" program?
It might provide some ideas you can use...

Sometimes things get out of order (especially if someone replies while you're replying), so I thought I'd clarfiy
That's why I used to prefer the Outline mode, you could follow the topic graphically instead of scrolling up and down
B/T/W I still get the Outline mode on my office PC using Internet Exploder 7. Outline mode is a bit dodgy, but I revert back to it when I have this sort of problem.As a side note, NI isn't the only vendor with runtime size issues. I just set up a new PC and installed Adobe Acrobat 8.1.2. 30.8 MB for a "reader"?! Why don't we hear more complaints about that?

Well, it looks like you're using the VI from here.
Suggestions:
Set the timeout (default 10,000 ms) to something longer. If it works sometimes and not others, the call may just be timing out waiting for a slow server.
The vi provided (and the one from the link above) do not have any connector pane inputs or outputs. How do you pass in the user name and password?
-
Try replacing the "Number to Decimal String" function with the "Format Into String" function.
Use a format string of "#%05.2f".

Yin-dee-ton-rab, psiam!
If you can you show us any code, it might be easier to help. Upload a picture or a sample of the VI you are using.
Questions:
How does the operator enter a user name and password?Are you using the "Prompt operator for input" Express VI?

I already used the DataSocket and it work but some times it isn't work becuase it need to re-access (web page need user and pwd) but we already put user and pwd before.We following this format..http://[user]:[pwd]@192.168.13.236:20080/[wep_page_name]Do you have any suggession ? -

The problem may not be in your LabVIEW code; it may be related to the remote device not freeing ephemeral ports in a timely fashion. The error code might tell you more.
Try using a fixed timeout (5 seconds) and check the error returned from the TCP open.
See these threads from the NI forums...

Adobe GoLive is a bit out of date (or dead now?!) but I wrote a simple javascript once that used Google Translate. I included the script on every page through a template. It added a translate bar consisting of a bunch of flags; it made my employer at the time VERY happy.
Example at http://www.ietlabs.com/ (at bottom of page)

Are you using the continuous run button? If so, the counter is reset to zero each time you press the stop button.
I've attached a modified version of your vi (LabVIEW 8.0).
I made the following changes;
Used a Select operator from the comparison palette instead of a true/false case statement. This makes the code generally easier to read.Changed the while loop's conditional terminal to stop on true. (stop sign in lower right corner; right click to change)
Changed the mechanical action for the Stop button on your front panel to latch on release.
Changed the value for the Less? comparison operator to 0.5, as you indicated in your original post.
Download File:post-949-1150195544.vi
:thumbup: Great job! You might want to explore the comparison palette a bit more. Press <CTRL-H> to turn on the context help and you will see some basic info on the different operators.

The simple solution is to never make misteaks or allow errers! (only in LabVIEW 8 of coarse)








MGI Releases Bezier Wiring Toolkit
in LAVA Lounge

QUOTE (jg69 @ Apr 1 2008, 07:45 AM)
I was originally going suggest that Bezier wires be passed over and that all wires be replaced with fibers (optical). It appears that http://www.dailytech.com/Sun+Flares+Laser+Interconnect+Technology/article11224.htm' rel='nofollow' target="_blank">IBM and Sun are interfacing CPUs this way. Propogation rates are higher and the loss per unit distance is significantly lower. In your example above, a tight bend radius could damage the 'fiber'. Darren could probably add a feature to VI Analyzer to check for this though :laugh:
Maybe "Jeff's Wire" is actually a fiber?
