LAVA 1.0 Content

Hi there,

I have one question.. Is it possible to discard an event (a boolean (button press) event)? I dont want the event to get triggered when i toggle the boolean from "True" to "False"

I know that the "Panel close?" has this feature available on the event structure (see the image attached) , but how to make it visible for the boolean events (or any other events)?

No - that's crazy talk, ...

Hi Chris,

"Crazy talk" is part of any good brainstorming session. I am just trying to contribute.

Well, their UI means that you can do what you're after. The way they've set it up means that soft commits (one's that you can eaily back out of, so it's really more of a "select" than a "commit") can be backed out of by moving the mouse out of the active area again, whereas hard commits (if you played with the interface for long enough, it asks you a question on whether you're okay with not clicking) require a "select" then a "commit" (by moving the mouse into the "yes" or "no" selection area and then moving into the "confirm" area). Confusing for us already comfortable with the way UIs work? Absolutely. Confusing for those new to computers? I'm not so sure.

But with new users we can just tell them not to click "Yes" if they have any questions. What we say for this type of GUI, "Just don't touch the mouse."?

It would have been nice if they added a little delay (half second or so) of no mouse motion before popping anything up the mouse is hovering over. Then it might be interesting to use.

Even if there were a delay, it would make me nervous. Imagine if the GUI was designed such that without moving the mouse, it kept onpening lower level screens until (without any effort on the users part) the ..... confirm order button is floated over for too long. It would be like the monthly book club "If you do not respond we will assume you want this book."

Give me a click, left-eye-blink, left-foot-tap, whatever, that allows me to DO SOMETHING to indicate my selection.

Take a look at this:

There are some interesting aspects to this UI.

Thoughts?

First thoughts....

It makes me feel like my mouse buton is stuck.

Forget about mouse-over to figure out what is under that thingy, you are going there if you like it or not.

Hi,

I have an issue and need the recommendations form you.

Currently, I am working on an old project which my company did it with LV 7.0. This is a big project and take a lot of time to develop. This is the reason why we try to find a way to move the program from 7.0 to 8.5 without rewrite the whole thing. The problem is this project use DSC and there are a lot of tags.

My question is there is anyway to move the program from LV 7.0 to LV 8.5 by converting the tag engine from 7.5 to 8.5. This relates to another issue as the DSC VI used to read and write data.

I hope that by your experience you can give me some suggestions.

I highly appreciate your time of reading and answering my question.

Warm Regards,

Thang Nguyen

MAX has a utility to convert your SCF and histories.

The read tag VI will get converted to shared variable reads.

If y have "Read Tag" VI's in a loop that use tag names to read from, then you can use datasockets reads to do the same thing.

Dynamic events can be registered for tags if required.

Thanks a lot. I am still trying to figure out how to parse the time string into seconds. I tried using the scan a value (from the string palatte) and then sending into Date/Time to seconds block, but no successful. I will keep trying. Thanks again.

Try something like this for your conversion. Read LabVIEW help for %T definition.

To get time in second:

also on http://zone.ni.com/devzone/cda/epd/p/id/18 there are some example VI's, how to get Windows timezone information (from kernel.dll).

Example is quite interesting if someone has to deal with WCHAR.

Hello,

Does this actually works for you ? I have WIN XP Pro and for me the only information that is correctly read is the timezone, all the other information that are read do not correspond to the actual windows date and time ; and the write function does not seem to have any effect

Any idea ?

Hi there,

Could some one explain little more about "Request Deallocation " this function? (Apart from whats there in the NI Help )

Can i use this in all the subvi's thats been called by the "Main" vi ?

Is there any limitation for the same?

Ahh but there are even fewer CLA w/ their CTSD! Going for CTSA followed up w/ a B O L O G N A sandwich

We used to have the very first person to get their "A" for LV and TS. We called her "The Architect-Supreme".

But what really prompted me to reply was mention of BOLOGNA! I love Bologna so much that I am not disappointed when my wife does not cook. It gives me another excuse to eat BOLOGNA.

Hi all,

Just wondering if anyone out there has looked into incorporating google earth into a LV app? I would like to have an app that can re-play a google earth "trip" based on a GPS track, perhaps with some zooming etc.

Anyone investigated such a concept? I assume it would involve some .NET or ActiveX work, maybe even some DLL calls.

Any advice would be welcome.

Cheers & Beers

Hi,

I use many of HHP 3800 in clean room and warehouse environement and we are satisfied.

Why is so important what I said?

For example because we are waves, we are affected by others, by others waves.

I explained to my daughter that we are influenced by people who are in the same room or in further rooms.

Only the presence of my neighbors diminish my potential, without theirs noise.

But look at it as an oppertunity Alfa. You can operate in more dimensions so with time you may be able to counter the negative vibes with an equal but opposite field.

BTW: I now concider The Fifth Dimension" "Alfa's Blog". This makes your blog the most read blog in the LabVIEW world!

Thanks for vibrating in a space I can sense.

Thanks for the replies... Using the "memory eraser" would be good idea....

Here is a link to the CLA prep doc.

Since you are already a CLD you are partially familiar with what you will see. As indicated in that doc I linked, you will be asked to develop an architecture for an application similar to what you developed for the CLD.

I can't say more because of NDA.

I hope that helps,

Ben

Hello,

Because of the NDA, those who have taken the CLA test will only give you general comments (there are a couple of threads dealing of that), nobody appart from NI can provide sample exams.

My personal feeling about all this is that it's ridiculous, the format and content of the exam are so confidential that I wander if they can be shown to those who take the test.

Should they have Men In Black's "memory eraser", they would use it !

Good luck for the exam

Hi,

I am looking to take up the CLA exam but not sure about the exam pattern. Is there any sample test paper available with anybody that can be shared. Tried NI website as well as NI India but it looks like they are not willing to help me out.

That doesn't surprise me at all - it's a feature that's closely gaurded by NI, and not something that's in the catalog (which is often the only products that your local office will know about). You need to have a very strong business case, and an even stronger relationship with NI to get access. That said, the method of writing in 7.x and opening in 8.x works perfectly, so not having native access to it in 8.x is more of an inconvienience rather than a show-stopper.I sure do! Do you remember me?

Thanks Aitor. I still need to learn a lot things regarding scripting.....

ZITAT(tcplomp @ Jan 8 2008, 02:00 PM)

Henrik could you help me how I could do that?

The strange thing is that 8.0, 8.2 and 8.5 work and 7.0 not (at least for me)

Just download the zip-file from MS technet: http://technet.microsoft.com/en-us/sysinte...s/bb896653.aspx

When running the application you should be able to enable the log. Perhaps you should only filter for LV7.0 in your case first. Otherwise you will get thousands of entries. Now click on the detailed help. Stop the logging process afterwards and have a look at it. Hopefully you will find a warning/error.

I haven't done that for a while. So just try it out.

Henrik

As I whittle my way through the "view new posts" I always have to return to top then click the view new posts link.

Not terribly hard, but when you go through 30 new posts it would be nice to have the "view New Posts" @ the bottom so I can simply click it when I'm to the bottom of the post, or better yet have the next topic button know that you came from view new posts page and go to the next newest topic, not just the next in the specific forum.

That would fit my use-case very nicely.
