I'm confused as to why the Read case needs to queue itself up. Reading the Queue happens every iteration anyway, so it doesn't serve any purpose to have a specific Read case to tell it to do so. Can you explain what you're trying to accomplish? Do you only want to process messages after hitting Connect?

I want only to start the COM-interface reading in the bottom loop from the upper loop. After it is started, it should do reading up to the upper loop commands idle.

Why not? What can be wrong here?

Thanks, Eugen

Hello,

I use a queued state machine in my program. The bottom loop is my parser and works in own VI. If I click connect my parser should start to read interface and triggers himself for the next read. But if I want to stop them, they will not stop. I see why, but have no right solution.

My bad solution is to flush the queue in state idle, but it works wrong, if I click any other button while waiting on reading (5 sek). In realy reading doesn't need 5 seconds, it only to show you my problem.

Can you tell the difference between a completely transparent modern cluster and a completely transparent classic cluster?

Anyway, attached is a VI with a transparent modern cluster, created using the simple method I explained. There's also a modern numeric, just to make it more obvious, so that you'll believe me that it is possible.

Thank you for it. It works good. I believe it now. The problem was in using of the paint tool. I select as first the transparent color for both - fore and background. Than I want to color the broder of the control with transparent color, but it works only for classic controls, not for modern.

And with rightclick on the border and selection with space key works for both controls.

In really.

I thank you for solution. Eugen

You can make the borders of 3D structures transparent:

1. Right click on the border using the paint tool.
   
2. Hover on top of the T color.
   
3. Press the space bar a couple of times. This alternates between foreground and background color. One of these should make the border transparent.

Can you post an example of completely transparent 3D Cluster (no borders and no shadow must be visible) here? Please. I don't think it's possible.

Sorry, I don't love/use private methods and properties.

QUOTE(yen @ Sep 5 2007, 08:29 PM)

That is too difficult for this. I wish it would be implemented in LV, like:

rightklick on

Control->Control Style->Classic

->Modern

->System (optional, if possible)

QUOTE(Tomi Maila @ Sep 4 2007, 05:22 PM)

You mean you want to do this manually for some VIs or automatically for a large number of VIs?

Yes, manually. I know I can use Control->Replace and then replace my modern object to a classic. But it doesn't work for clusters and arrays. Furthermore if I replace a object to any other, then the new loses properties, like formatting.

Eugen

Hello, I wish I can change the look out style of FP elements.

E.g. I created a modern cluster or array and want to change it to classic style and make than boarders transparent.

Eugen

For UDP broadcast, a UDP server should run on the XBOX and wait for your request. If no UDP server ist available, than you can try to connect to the XBOX over TCP/IP in a for loop.

Eugen

P.S. if you know any program, which do, what you want, than you can use any sniffer to hear up the traffic between this program and the XBOX.

Thank you Eugene

This is most helpful and instructive. It's a much better solution than I've been using up to now!

Can I add hree comments (hopefully helpful)

1) The Flatten to string is not required if you format the queue as a cluster.

Right, I use only queues of type string in my programs, because of modules compatibility. For this example it is not requiered.

QUOTE(jbrohan @ Sep 3 2007, 02:25 PM)

The Buffer size control(terminal on BD) inside the case too.

One more comment from me:

Build array VI can eat some CPU, so you can better use "replace array subset". Than you have to know the max. buffer size in developing phase and probably limit the buffer size control to this max. size.

Eugen

I am a new LV user and I take it so, how NI engineers have developed it.

I don't use express VIs, but I use autowiing, autotool selection and alignment. E.g. it is not possible to see every pixel on your FP, so you will take more time to align elements without autogrid. IMHO.

Eugen

Hello, here my example code to show high frequency data with low CPU load.

Eugen

I am working with data monitoring for IMUs. But I newer try to integrate or differentiate a signal under Windows.

1. And if I should do it, I need a TIMESTAMP for EVERY sample or I need to know the sampling frequency.

2. I would say integrate or differentiate every 25th or 50th sample is a wrong way to reduce CPU load. This way means, that you loose some important informations about the signal. The right way would be to integrate every sample and buffer them. After them you can show data with e.g. 10 or 5 Hz. So you will dont get more than 5% CPU load.

3. To log data on HD you can use the right sampling frequency, it doesn't need some CPU.

Eugen

P.S. AND I AM SURE that LV is not much slower than C/C++ or other programming languages. You have only right use it.

Tools>Options>Alignment Grid = 12 pixels.

Thank you. I found it in one of LV VIs.

Shit, 12 is a bad choise. I will stay on 8.

Thanks

QUOTE(orko @ Aug 29 2007, 03:05 PM)

I'm assuming that you are seeing this is in LV 8.0?

Hello, what is the most appropriate alignment grid for Front Panel? I don't more know my default value. I think e.g. on default sizes of controls.

If I place a LV control (e.g. 39X20 = default size of a boolean button) to my FP and move them, but my alignment grid is 8X8, then I get some little problems (see attachment).

Eugen

P.S. I know I can group/ungroup or resize buttons, but I want only to know what is the default grid size after LV installation.

If I create a new it doen't more happen.

If you open the BD of the VISA Configure Serial Port.vi and copy the Property node inside them to your BD, then you will get this comic behaviour.

Eugen

QUOTE(shoneill @ Aug 29 2007, 12:39 PM)

You sure this isn't just an auto-wiring problem? If you move the property node up until it aligns with the wire, it should exit to the right.....

Shane.

Yes, you are right. But why this auto-wiring problem?

Eugen

Hello, does anybody know, why Instr. property node has the output on the top side ?

Eugen

All is right, what you wrote. It's only one alternative way to do it, but the MOST REALIBLE is to use App.Kind property.

Eugen

Or you can use the property "BD Size" and compare it with 0.

Nice example Eugen, this could be worked into something suitable for the Code Repository, as well as Wiki.

:thumbup:

Thank you, but this example is not completely made yet. If you want tu unsubscribe some tasks (modules), you have to duplicate the subscribe case in dispatcher and replace the true constant to false.

And I have two problems too:

1. I want to mix the communication with Notifiers and user events (I think here on a 3d topic table or array).

2. private topics should stay in module and must be not published to other modules, so I don't want to subscribe them on dispatcher.

Can you say how you done it in LV 8x, please ?
