In the palette "File I/O">>"Advanced File Functions" there is a function named "Flush File". It is probably an "antique" function, when computers weren't that fast and writing to disk stopped every other execution (including the mouse) on your computer.
Open once the file and keep the reference open as long as your app runs. Write to the file as wished and every time after a write add "Flush File".

When you offer no option for the innocent or opressed to defend themselves, then fairness is lost and bullies win.
The joke of the poor-innocent-back-yard-researcher-that-has-to-be-protected was something for the beginning of last century, antiquated nowadays.
Patents is a billion dollar market. When a firm is sold, the counts of patents this firm holds is an important factor on the selling price.
When I hear that such stuff gets patented like: "mouse click on a window scrollbar" or "sperma treated with some hormone to enhance reproductivity" then I get serious problems concerning the idea of patents. :thumbdown:
I prefer the way of view, that when others take your Idea, then it's a greate one, otherwise it's bullshit. :thumbup:
Free market means that you have to be better than your concurence, not that you have to kill them by kicking in the ######, this is more wild-west.
...just my $0.02 opinion.

I wouldn't mind having the scripting possiblities as a tool-box. I probably would even be one of the first bying it. It extends LV so much and one can create help tools for easier programming.
I even doupt there might be some legal problems. The ability to write code from code would mean that one could build some new programming language from LV and distribute it. NI wouldn't be glad seing that people program LV without bying LV development suite...

If I interpret this chart correct, the biggest traffic are after lunch and in the afternoon of the american east-coast.
Considering that in Europe (switzerland + germany at least) we have GMT+1. This would mean, best lounge times would be (for me) 8 p.m. and later.
Uh, usually at this time I'm at home enjoying a tea and dessert, and not reading/writing LAVA forums. Others would even say they enjoy a movie on "home cinema", but since I have no tv-set...
My best time for joining a live chat would be in my early morning hours (7-9 a.m. GMT+1). Afterwards it's getting hectic in the office.

I bring up this topic because I just installed LV7.1 on my computer and all the nice vi's referenced in http://forums.lavausergroup.org/index.php?showtopic=208 are now password protected! :thumbdown:
NI could really make the scripting tools avaliable for everyone, since (I checked) they are there since at least LV 5.1. If they kept hidden, because of fail-safe reasons, I think they are now quite good tested.

Just got LV7.1. It seems NI closed the doors to these vi's... they are password protected! :thumbdown:
:!: If you have an open version of these vi's, copy them to a save place!

I don't know if in LV7.1 it's possible, otherwise, count the samples acquired and if needed create a new file:
(10Megs) / (5channels x 4bytes per value) = 524288samples / 655536samples per second = 8 seconds
Means: after 524288 (=2^9) samples or 8 seconds you'll have to create a new file.
Best add an index to the file or it's extension (in windoze) and wire it to the Write LVM file.vi

Not quite a code challenge, I'v already done something like that, with quite some statistics (haven't the code anymore present, must have lost when I last changed job
)
You'll still have to wire them into your code, but less complicated than with sequences. If you make the icon footprint small (e.g. a small clock, 8x8pixel), it won't disturb your code too much.

My favourite is Microangelo, not abolutely fee (a few bucks) but offers lot things like: extract icons, change icon on a file, create multi size + color depth icons, animated icons,import pictures and shrink,...

I'v just seen we have a full chat room... no more "trial version" :thumbup: :thumbup:
Maybe we can negotiate a fixed chat time.What do you think?
This could be a bit difficult, since we have members from America, Europe, Asia, Australia, Africa(?), all with different timezones.
I'm not soooo used to chat-rooms, but I think best would be to log in and wait, or send a PM (since we see who is online).
is the chat-room already considered as an alternative for the LAVA-meetings?

It has been suggested that the splashscreen loads the main application. It is not necessary since if both splashscreen and main VI are TLVIs, they'll load and run simultaneously at startup. If the splash screen is lightweight and opens quickly, it will also prevent the "loading..." screen to appear when the main application takes too long to load and open its FP.
That's the way I always did it... load+open splashscreen, load main app dynamically, end splashscreen.
This is a much easier method. :thumbup:
Another question rises up there: how do you know when the splashscreen has to close? Is it just a timed loop, or do you have any sync (occurence or something else)?

Edit: I just noticed you're using LV6.1. For you, it's undocumented, but it works.
On LV 6.1 this option isn't avaliable, it found it's way to labview.ini in LV7.0 .
I have a LV7.0 version on my computer running, so I can participate in LAVA-forum... Till I get the money for the newest version from my boss...Didier

Does anyone know for what the setting FancyFPTerms in LabVIEW.ini is?

I'd like to advertise my products on BabVIEW - How do I create pop-ups? Are you going to add pop-up Support? How about HTML while you're at it ;-)?
jpdrolet: Seems you'll have to consider in adding a few more NIGHT-lv-wire-sessions... :laugh:

The voltage range is up to 100mA
Ohms law seems to be still quite difficult...
Think you meant 50mV for the 50 amps and this shunt.

I'm with you...
don't forget that the icons should be able to have 256 colors or more (with 16 colours they look quite ugly and like from last century on modern OS's).

Soon they only want 'one button' to do the whole thing
Like general computer rules...
In win 3.1 every setting was within 1-3 mouse-click. in XP it's withing 6-9 clicks :thumbdown:
Reminds me the "aunt Olga"-test of a german computer magazine. An XT (computer generation of somewhere in 1980) won in time against a Pentium IV in sending an email to "aunt Olga", including boot, connecting to the internet, write mail, send, shutdown. :thumbup:

If you are afraid of loosing data over the net, then you'll have to add an acknowledge:
1. Send the data to each client
2. each client calculates a checksum from the received data, e.g. CRC16
3. the clients sends the checksum back
4. if the server gets a wrong or no checksum back from one client, he sends the data again to this client.
This would also mean that each connection is handled (in the server) separately, so your server exactly knows which client doesn't work correctly. A broadcast won't work.

Do you also have it as LV 7.0 ?

Hi Sarah,
If you have pasted your sub-vi into your diagram, then the program flow waits until your sub-vi finished execution (except operations that have parallel dataflows). Your sub-vi executes all the code inside itself until it returns. As the vi is loaded at program-begin in such a situation, there shouldn't be any exception in the sort of exit before loading.
I just see two possibilities:
1. Your sub-vi is not in the main (user interface) loop. There the loop and your sub-vi executes in parallel and your sub-vi is run just in the beginning of programm execution.
2. You call the sub-vi (or a sub-vi in the sub-vi
) with vi-server. Then you must be sure to have the method "run vi" with its property "wait until done" set to true.Didier

If I'm allowed to make the first comment...
A List of online users would be nice, actually you write into the dark, possibly reaching nobody.

How to get the reference of a control inside a tab
in LabVIEW General
Posted
If you get the reference from vi-server then use it this way (don't forget to close the references of the elements not needed anymore, or you loose memory)
The order of the control references in "Pnl" and "Page" is the creation order of the controls, independent of the order designated by the user (via rmb: "reorder controls on page").
