This is really nice. Not sure if the NXT is looking at the colours or just doing a preset routine. Excellent nonetheless.

Hey, I put a warning up... and I put it in the LAVA Lounge. Besides, I'm just trying to raise awareness. Tryin' to help the ladies out there...

Warning! Beware of Language Content! Use Headphones...

Am I advanced enough? Am I really an "architect"? I shouldn't have to think such things.

I agree with you on this. I have always been open about sharing my knowledge about LabVIEW. I have put on countless presentations at various LAVA meetings because I truly believe that we should all be programming at the same advanced level. Those that think LabVIEW is not powerful or cannot do this or that, think that way because no-one has shown them the light. We all need to give up our secrets for the common good.

QUOTE(PaulG. @ Apr 28 2007, 08:01 PM)

Yes, it's about getting at the root of the feature or technology and figuring out "why the hell should I use this, and why should I care". One of the reasons I started the Wiki section of the site is for this reason. There, we have more time and can focus on explaining features and how to use them in various use cases.

Recent posts have been downright mean! If you don't think the topic is worthy of your time or effort to respond then move along. You don't have to respond. Especially not with a smart ass remark that just makes you feel better. Veterans around here lately seem to be ganging up on new members in the same way schoolyard bullies do. Yes people, we know you're ace LabVIEW Guru's and it seems very silly for someone to be asking: "How do I get a VI to pop-up when I click a button". Well, I was in the same position when I started LabVIEW. It took me 3 months of development before I found out how to do this simple thing myself! In the end, my company hired an Alliance Member to come in a show me this and other tricks. I only wish I had something like LAVA back then.

What are you doing to help? Why not write a Wiki article describing how to do this? Why stop there? Write an article on all of the issues plaguing new users. I am appalled at the tone and treatment of new members and those where English is not their first language. It's unfortunate that LabVIEW is not a very popular language since those members cannot find help in their native tongue and so resort to joining English forums for help. It is what it is. If in doubt, ask probing questions, get to the root of the issue. Be constructive and helpful. If not, don't respond! Please.

It used to be that, if you were a LabVIEW user among users, there was a certain bond. Others would help you overcome hurdles and get you hooked on LabVIEW. What ever happened to that?

You should be forewarned that this is not just a place for you to get answers to your questions.

i know i can send email by labview but I mean the user just enter his pass word email and TO : then that VI will be sent can I?

What 3rd party program are we talkin' about here?

Your solution with cluster queue is interesting, but have a disadvantage. My question is: what happens if I only want to change the interface (if user changes program settings) without to send any message to visa?

Are your devices, serial? I think only serial devices really need to be closed to release the port for others to use. GPIB devices don't have to be opened or closed. At least not anymore. Other than Visa Open or Visa Close, I'm not sure what kind of instrument command you want to send.

Regardless. If this is still the case, you can do this with queues as well. Keep in mind that you will need different queues for different types of tasks. The example shown assumes that you are working with the instrument task queue:

There are many solutions to your problem. User events can be used as well. However, I would even argue that you don't need parallel tasks anyway. Why can't you just do everything in the main state machine? I'm not sure of the benefit in your case. Perhaps data saving would be better off in parallel if you have lot's of data. What is the speed of the overall system?

QUOTE(JFM @ Apr 5 2007, 08:14 AM)

Tomi, I think you are safe

If I remember correctly, bsvingen did some testing of this in another thread (that I can not currently find).

The result, as I recall them, was that the LV2 global was faster than using queues.

Hmm, I think we should place some bets here. LAVA could use some donations .

My money goes on the queue.

QUOTE(Eugen Graf @ Apr 17 2007, 07:55 AM)

Who can say why I get the timeout event in the first loop, after clicking on "Generate" button?

Your code does not make sense:

1. In the top event structure, you are generating a user event.
   
2. The bottom event structure responds to this and executes the <Command> case.
   
3. The top loop is ALSO registered for the same event. It ALSO responds to the same event however it's too late, the message has already been removed from the queue from the bottom event structure. It then just iterates a timeout.
   

What is the purpose of your design? Multiple recipients? If so, then you need to use a different approach. See attached image:

QUOTE(Tomi Maila @ Apr 17 2007, 07:58 AM)

Agreed.

QUOTE(Eugen Graf @ Apr 17 2007, 08:23 AM)

This is not true. You can have multiple event structures without problems as long as they are not using the same event registration refnum.

QUOTE(Eugen Graf @ Apr 17 2007, 08:23 AM)

Another option is to create the user events in the main task VI and pass this to the other tasks, however register the events at the task level.

QUOTE(Eugen Graf @ Apr 17 2007, 08:36 AM)

You are presenting multiple issues here. Are you trying to get speed and less memory, or are you trying to solve your problem? The reason I'm asking is because you don't need to switch to a completely different architecture to solve your problem. Queues are pretty powerful on their own and still viable for your situation. From what I can see, your problem is that you are mixing your communication mechanisms. Why use "Set Value Property" on top of queues? You already have the pipeline so utilize it. See:

Thanks for the info, rolfk and Aristos. Now everything is clearer now. I thought controller references weren't strict types, since there are times when LV seems to know more about them. ;-)

Best regards.

Bundle is good most times, but not so good for a typedef. Typedefs would be the real value of this, I'm thinking.

Doing OOA&D on a coffee maker is a standard classroom topic used my many to teach the principles. Another one is a bank machine.

Just want to apologize to all for the latest server outage. This was purely my fault and not due to any hack\crash or anything of the sort. Apparently, when you tell the server software to create a backup of all your domains on a daily basis, it does what you tell it... until your hard drive fills up! How nice! :headbang:

the software service providers that provide the best service to their customers and treat them well will win (I hope).

Can't you use a bundle node? You like dialogs?

BTW, you don't have to use NI's OPC server. Find one that works and use it.
