QUOTE(Noxious @ May 3 2007, 04:36 AM)
the bad news: that's really a lot of work - and the reason why people use the myODBC driver
. If you really want to connect to a mySQL DB without the ODBC driver you have to connect via TCP/IP and you have to programm the complete mySQL protocoll in LV. I said id before, that's a lot of work. Natvie mySQL Support is on the feature list of my ADO Toolkit for years, but I never had the time to implement that.QUOTE(Noxious @ May 3 2007, 04:36 AM)
Or, how can I automate the installation of the above driver into an installer?If you are using LV 8.2.x then that's easy: just add the myODBC driver installer in the section "additional installers" ... You can add additional installers in older LV versions, too, but that's not so convenienet like in LV 8.2 ...

I've got a built application that hangs around in the background after I get an error trying to access a VISA port. I have to use the task manager to shut it down. However, when I look at the Processes in the the WIndows Task Manager it's still there and I can't shut it down (End Process and End Process Tree do nothing). I have to log off to get rid of it. My IT dept doesn't know what's going on. Has anyone seen this?George
I wish I could help, but I hear this for the first time ...

I am aware of this issue but didn't think it was critical enough to fix. Now that it's "noticed" I guess I have to fix it now...
hmm ... if you broke it, it's up to you
if invision broke it, I'd wait for the next update
if you're lazy: I'd wait for the next update anyway

that's a difficult question, I just can guess:
IMHO there are 3 categories:
1. to slow, e.g. if you get aliasing effects
2. fast enough - the speed of the accquisition is fast enough to sample the signal
3. to fast: you get more data then your system can handle
I'd consider 1 kHz as standard speed, 100 kHz as high speed

perhaps with a button to click. Enough clicks by enough members could send the topic to a different section, as described above. Perhaps this can be done as a ratio:If I were the Admin here, I'd refuse to do this, because this means a lot of work. This "simple little button" means, that you have to go through the PHP-sources of the forum software, search for the right position to implement that code, eventually change the database, etc ...
As long as this feature is not provided by the forum software "as delivered" that means, that you have to redo this on every software update, that comes along, you have to rewrite your code, adapt the buttons to new templates. I'd calculate at least one day for the first implementation, and at least a half day for the implementation on the further releases ...
Moderators are IMHO a more suitable way to repell HHs and encourage newbies.

However over the last week, with all that has been going on, I have been looking at the post (not many) I have made, thinking were they suitable and valid; should I really be on LAVA at all.hmm ... that's a stupid question in my eyes:
if you are interested in learning and serious with labview you and your questions are generally* welcome.
generally* because, maybe the long term users do not want to answer a question, which has been answered several times before. The reason is simple: that's boring, and e.g. I am not here to waste time, but to read about topics, which are interesting and contain new aspects. So the worst, that could happen to your question is, that maybe you'll get no answer.
But if your questions are specific and you point out the issue as exactly as possible, I can not find any reason, why you should feel misplaced or even worse "not worth to write here" - that's bullsh*t.

Sounds like a good solution to me, but I'm not sure we should lump all of this on Mike - it's going to be a lot of work, and Mike already does a fantastic job of supporting LAVA with no financial gain. That takes me back to one of my earlier ideas: is LAVA at the stage where it's large enough to warrant a couple of Moderators standing alongside the Administrator?as I allready wrote: I volunteer as Mod ... (if Mike does not find anyone more suitable ...)

QUOTE(Jim Kring @ May 2 2007, 04:42 AM)
How about this? When a homework hustler posts a message that does not conform to the forum rules and expectations, a moderator will do the following:-
move it into a special "Homework Hustler" forum (maybe, not syndicated via LAVA's RSS feed)
-
reply to the topic with a standard, canned response (which includes a "Homework Hustler" emoticon, of course) explaining why the posting was rejected and how to "try again"
-
lock the topic so that neither the homework hustler nor the homework hustler hecklers have a chance to butt heads.
Moving the posting into a special "homework hustler" forum will create a nice archive that will amuse the homework hustler hecklers and create good examples of how not to post questions to LAVA.
100% ACK
locking that topic makes sense to me, because then nobody can choose the *wrong tone* in an answer. A standard answer is a more or less friendly but clear signal, that we don't like homework hustling around here.
@Admin
if you need a Mod - I volunteer - if you don't find anyone more suitable

move it into a special "Homework Hustler" forum (maybe, not syndicated via LAVA's RSS feed)

Hello all,I am trying to decide what would be the easyest and most reliable way to control several machines that are running the same test program from a remote machine running a master program. Data Sockets? VI server? Web server?
All Ideas Welcome.....
:worship: 
I am currently planing a test system, which has 5 nodes (cRIO) and one master (IPC). I am not yet sure, if I should choose TouchPanels for the slave control, or a *small* IPC, but I am allmost sure, that I will use the cRIOs.

Do you have any recommend for em, which one I should use?I don't really have a recommendation, because I only had one project at all where I had to communicate with a SPS, but I used LV 7.1.1 and a OPC Server with DATASOCKET and it worked fine. This combination is fast enough and reliable, so if I had to do this again, I'd use OPC/Datasocket again ...
I encountered a bug in the Datasocket VIs of LV 7.1: I was not able to keep more than 5 Writing Datasocket connecitons open simultanously, because then LV crashed and frezed the PC. But when I was working with datasocket attatched controls I had no problems at all.
The reason why I was trying to keep the connections open simultanously was, that the initialisation was rather slow (about one second ...)

HI all,I have one question, can I program my VI to be for admin or guest??
the good news: yes you can (you can programm allmost anything with LV, if you have enough time ...)
the bad news: if you don't have the DSC Module, you have to code this on your own, there are no functions for "user management" n the VI palette of LV

I found an http://zone.ni.com/devzone/cda/tut/p/id/3466' target="_blank">article at the NI Devzone, which might be interesting for you. Maybe this is a good point to start?
On the other hand: if you are thinking about "playing around" or "home automation" - 2 weeks ago, I bought myself a Siemens LOGO! starter kit for 150 Euros. Maybe this technique might be more suitable for your purposes and if you are used to LabVIEW, you will have no problems to get familiar with the LOGO! The big advantage of a LOGO! is, that you don't need any signal conditioning, etc ... it's all included in one small device and you can switch 12/24V or 110/230V with "ready to go out of the box" devices. If you want this from NI, you have to buy a FieldPoint System, which is at least 5 or more times as expensive as this cheap logic module ...

I agree with Michael in a way. There has been a relative harsh tone to a few new members, not to all.
I concur with Michaels position, that newbies must not be bashed just because they are new to LV and ask questions, which are "to basic" for some of the gurus around here. I needed e.g. 2 month to find out, how to change the connector pane pattern, obviously I missed that part in the getting started manual, and I have not forgotten that. Input from an other human makes learning much easier, and I'm always willing to help out. So if whoever thinks that a question is „to simple", he/she is free to ignore it. No one is urged here to answer questions, which are *below its level*. But I'd like to ammend, that teaching the apprentices has allways been a fixed part in mastery.
The other side of the medal is, that the amount of NULLs is increasing - not only here, but in other communities, too. If I say NULL, it's a synonym for people, who are not serious with learning, their only interest is to get a solution as soon as possible, and are arrogant and/or brash. I, for my part, have a problem with those people, and it's not funny if you get CALLED / eMailed / PMed by those people, just because they managed to find out your telephone number or email address and think, that <sarcasm> you have enough knowledge to solve their problem (of course they only take the best .... <argh>)</sarcasm>. If I compare LAVA to my living room, this behaviour is like: someone you don't know comes in, throws a can full of trash in a corner, shows you the finger and demands, that you clean this mess up immediately, because you are experienced in cleaning up ...
IMHO those people need some adequate, clear words. Choosing an arrogant tone is a proven means in discussion forums against dumb bricks. Being arrogant or hash is not intended to show the world that I'm a super duper whatever guru, but just a good way to get rid of annoying NULLs.
I know from my experience from other forums, that from time to time you have to bash the worst ones, to keep up the discipline
. Other potential NULLs may read that and get put off. If you don't, you'll attract more and more of them and the forum will become unreadable / the SNR will increase.to cut a log story short: newbies = welcome - homework hustlers = go somewhere else, nobody likes you, nowhere! Why? because nobody likes the idea, that he does the *work* and someone other gets the *merits*.
Concerning good / bad language: it took 55 minutes to write this post, inclusive spell checking. Checking it's language as a non native speaker is a way to express it's appreciation, too. And even it's not perfect english, it's at least readable (at least I hope so) and not a post like

If you've got USB you could try http://sine.ni.com/nips/cds/view/p/lang/en/nid/201630' target="_blank">one of these (USB 6501) for only $99. DAQmx compatable, using an express VI you'd be done in 5 minutes or less with the DIO part.the USB 600x or 6501 device are nice, but if you e.g. need continious DIO operations, they are not suitable. So my first choice, when considering to buy a DAQ device from NI, would be to buy a M-Series. The small ones are not *that expensive* and you can use them for a long period of time before they become *really* outdated.

I use an occurence AND a global Variable in my dynamic called *SubVIs*:
http://forums.lavag.org/index.php?act=attach&type=post&id=5640
The occurence stops the SubVI in *normal* operation and I use it, as long as my Main VI is running.
The GV is set to false at the start of my main VI and is set to true, when my main VI stops. Ok, that might sound a little bit paranoid to you, but the GV ensures, that each Module is killed after the stop of my main vi, because it remains TRUE as longe as there are any callers. Even if I miss an occurence by acciendt, I can be sure, all Modules are closed when my SW stops.

I have a question about the LV 8.2.1 Installation:
An AE at the Hannover Industry Trade Fair told me, to install 8.2.1 in parallel to 8.20. When I start the LV 8.2.1. installer, it seems, it wants to replace 8.20.
Have you installed in parallel or replaced 8.20?

just add the myODBC installer in this field, and it will install after your application has been installed. If you need more then one installer or if your installer is an *.msi file, you maybe have to create a batch file, pack all these installers together with the batch file into a self extracting ZIP-file and make the ZIP-file start that batch file after extracting ...
