Thank you for loving Russia :thumbup:

I think this site is great and just funny.

Currently I live about 10+ years in Germany and work for a half-military european company. It's very good the "Cold War" doesn't more exist and a globalisation of the world is growing.

Eugen

Hello LAVAs,

please look this site, it's very nice to understand Russia (if you want)

Please give us some context on that almost-statement - at least an emoticon.

I would move this topic into LAVA Lounge if I would moderator of this forum.

What do you think about this article? Please comment, I need it.

Assuming all the code is on one machine, why not use user events with multiple subscribers registering for the event? In effect it's similar to a notifier but with the ability to work via an event case instead of a function.

Once you register more than once, the event gets passed to EACH of the registrees (is that a real word?).

It gives you essentially a 1..n link, albeit without the Queue (backlog) part.

Sample VI Attached (LV 8.2.1).

Shane.

PS I just realised I forgot to destroy the two user events when the program finishes.... Oops

Yes! But UEs have some disadvantages:

I can't flush UEs

I can't preview UEs

I can't get status of UEs (need count of elements in my programms)

But for this one issue of course it's right alternative.

@Alessandro

My implementation of Client Registration is like yours

QUOTE

You also check the name of the Queue. Ok, but what will happen if two or more "clients" want to use the same name?

In this case I compare the queue reference number, not the name of the queue. Is it a good sugesstion to improve your registration process?

Very nice video for LVOOP beginners, very easy to understand.

Thank you

I use it when i need to dispatch message around the code from one point to different parallel loop for example suppose a quit message or acquired data to send to datalogger and to data viewer simultaneously

Ciao

If it's only this use-case, than you not really need the overhead, you done in our example. It can be much easyer, like in my first suggestion, where you open all needed queues at the begin of the programm, and close all at the end of the programm. So each parallel loop can send to each other, bacause each loop get all queue references as input.

What is to open to see the principle? Do you have an example VI ?

Do you use a "Array-DB" as container for all created queues?

P.S. sorry, I see now two example VIs

Ok, say me please when do you use this?

And if you want, you can look on this http://www.labviewtutorial.eu/download/file.php?id=655

And more complex and more universal this one http://www.labviewtutorial.eu/viewtopic.php?f=19&t=9

I have the need for this functionality and am playing around with the alignment of the combo box on the table. Did you have to customize the combo box itself to achieve good registration with the table cells below? At best, my first cut looks poor. Your's looks nice.. Any tips?

Wes

No, I didn't customize Combo Box. I try always to use System Controls, not theese from LabVIEW Classic or Modern Palette.

can anyone explain me more about the state machine,because it sounds very good for my programming.

tq

Open the State Machine template from your Getting Started Dialog and switch Highlighting Mode on. So you will see what happens if the VI is running.

The question's a little confusing. How are you using your LVOOP class in C++? Are you calling a LabVIEW-built DLL that creates and uses LVOOP classes?

To flatten the LVOOP class appropriately, you will need to use the LabVIEW Flatten to String function. You can create a wrapper VI that calls this function with a class input and create an exported DLL function to call this from C++.

I think to create a structure (=cluster) in C++ with all elements what LVOOP Class Contol Cluster has, than cast them to binary string (or byte array) and send over TCP/IP.

Hello LAVAs!

I want know if it's possible to flatten a LVOOP Class to a binary string from e.g. C++, so I can unflatten them in LV to a LVOOP Class ?

Thanks, Eugen

I think it's something for X-Controls CR

QUOTE

I use Combo Box, because I can change the Size of this control to the size of the table cell. Can I hange the size of a ring control? I didn't find this property.

P.S. and here is the Front Pannel of the VI.

QUOTE (Justin Goeres @ Jun 24 2008, 06:18 PM)

In my experience, things like this are really tough to implement because there are lots of weird things that can happen after you display the ring control.

The first one off the top of my head is what happens when the user pulls down the ring control, but instead of clicking inside it to select something, they click outside it? Normally, that's the behavior when the user wants to cancel what they were doing and exit the item selection without changing the current value of the selector. How do you handle that case?

I'm asking not because I have an answer, and not because I think there's not an answer -- I just mean that the answer isn't obvious to me right now, but your users will expect it to work that way. I've historically found that replicating all the expected behaviors in a LabVIEW control is really hard if not impossible. If you've got a solution, I'd be really interested to hear it.

Of course I handle that case. I replace the Cell Value in the table only if the Value of the Combo Box was changed (Value Change Event). If the user will klick every else this event will not happen.

Ok, thank you, I just made it.

Hello, does anybody know if it's possible to make something like this in LabVIEW ?

Thank you

I don't understand what it is you want to do. If you want to change the output based on the type of the input the easiest and most reliable way is to use a polymorphic VI.

Another option is to just use DBL which should cover most other representations, I believe. OpenG has a function which does exactly this and accepts DBL. It might have polymorphic versions, but I don't think it does - the cleanest thing is probably to output the double value and then convert it after it leaves the subVI.

Yeah, polymorphic VI is the right solution for this, I think.

Thank you, Yen

Hello,

I have to generate a random unsigned integer from 0 to max. possible.

So I take "Random Number 0-1.VI" and multiple it's output with eg. 65536 (for U16). Ok, but if I would change the representation to U32, so I want programmaticaly know that I have to take 2^32 for my max. value.

Is it possible to get the representation of the wire? Should I flatten it to binary and use type string for it?

Here the screenshot

Thank you. So if I have NO inheritance in my LVOOP project, than it's always better to use static dispatch.

I should use dynamic dispatch first if I have some child classes ?

Why to use static dipatch member VI? It has only disadvantages to the dynamic dispatch member VI. Do it have less overhead for LV?
