Hi, thanks for your reply (also to all the rest) !!

Do you know where I can find this VI ?

Thanks in advance ! :worship:

It is in the signal processing --> signal generation palette...

I need to do continious measuring for six month. I use DAQpad 6020e. Of course i have 16 channels, and I want to use them all.

For the acquisition rate is about 100kS/s.

Actually I want to get the waveform data, and then save it into file. I want to be able to read the old data again if there is a problem occur. So it will be large amount of data in drive. what should i do to manage the data??

I would use tdms files in this situation. They are fast, compact, and indexed for faster viewing of incremental data. Search ni.com for tdms and you'll find quite a bit of information.

any suggestions?

Check out http://forums.lavag.org/Import-Web-Service-function-and-WS-on-Java-LV-85-t11369.html' target="_blank">this thread. It might have some useful info. We had problems with our WSDL as well and got it working with a different method that I outline in the linked thread.

This is my first forum post. I have a large number of Boolean indicators on the front panel of my application that simulates railroad movements and signalling on a track diagram. I want to have these indicators contained within an array so that I can write Boolean state info to each indicator without a lot of block diagram wiring, but don't know how to do this when the indicators are dispersed at various locations around the front panel (vs. adding an indicator to a rectangular array "container" in the usual way when the front panel objects are built).

Welcome to LAVA! You can do something like this:

It allows you to place your indicators wherever you want, but still pass them through a state machine (or any other architecture) on a single cluster wire. Just build a cluster constant to initialize them all.

Are there other things that I should be looking for?

How much free memory do you have? I ran both versions using the "Run Continuously" button and did not notice any performance lags or memory leaks, but I'm thinking that if you are running into low memory problems and having to use swap space that could slow you way down.

I'm on a T7200 @ 2.0GHz with 2GB RAM for what it's worth.

QUOTE (Mark Yedinak @ Mar 13 2009, 10:28 AM)

At present, both versions of code that I have included here take approximately 15 seconds per image for the decode.

I am also seeing load times of well below 1 second. Scan Lines with queues is taking nearly 0.5 seconds, but scan lines is in the hundredths of seconds. Are your real images much larger than the sample images you posted?

Is that a typo or an Aussie term I'm not familiar with?

In any case - probably not a good idea to forward too much to your boss unless you're getting all of your TPS reports in on time.

Well... hypothetically speaking, I could copy an unobtrusive stand-alone executable to this machine and run it. It's just when there's a "setup.exe", "*.msi", or other file of that sort involved that I get instantaneous permissions errors. And even if I did put an unauthorized *.exe file on here there's a good chance the Computer Police would spot it and wipe it off. But that takes awhile and I could just recopy it. Hypothetically speaking, of course...

:ninja: I see. I'll try to remember you (and others in your situation) when I post code. Screenshots are good :thumbup:

QUOTE (Antoine Châlons @ Mar 11 2009, 06:32 AM)

Because when I tested it on my computer I disconnected the path constants and I wanted to know which file was loaded first.

I would have made the dependence with an error wire instead if I could but the 'read spreadsheet file.vi' doesn't have any :thumbdown:

:thumbup: OK

what i want here is can you guys give me a simple example, truely i'm a beginner with this LaBVIEW..

bmoyer pointed you to a good example. Did you look at it? Do you have any specific questions about it?

Hello everyone in LAVA...

currently i'm working on my project by using LabVIEW.. I want to use serial port (RS232) to control a humididty sensor and one servo motor.. How am i going to build the control and monitoring application by using this LabVIEW? Please give me a guide.. where should i start? Thanks..

regards,

Mindmoody

I would start here...

1. Turn on your computer

2. Open LabVIEW

3. Click "Empty Project"

Seriously though...that is a really vague question. You need to start by learning enough about LabVIEW to be able to ask a specific question. I would recommend the Basics I & II classes offered by NI, or buy LabVIEW for Everyone and go through it on your own. Either one of these methods should give you enough knowledge to write a simple serial communications control program.

Hi,

Is there any way to do window title in one button dialog?

You'll have to either make your own dialog, or you can use the 3-button dialog (which has an option to customize the title) and wire empty strings to the left and right buttons.

QUOTE (star @ Feb 27 2009, 09:25 AM)

Now you can see what my output string looks like and i look at some waveform graph instead of an XY Graph and i still couldn't do it.

Thanks for your reply

Use Spreadsheet String to Array.vi and pass the output to your graph. If you need more help than that, http://www.urbandictionary.com/define.php?term=RTFM' rel='nofollow' target="_blank">RTFM.

QUOTE (star @ Feb 27 2009, 04:32 AM)

The reason why I want to make a graph is because I am reading some values for a text file and then place the values on the graph. The x-axis is the number of items in the file and y-axis are the values. I made a code that reads from a text file and I have attached it below.

We don't know what your output string looks like, but essentially you need to convert your data to an array of numbers and pass that into your graph. Because your x-axis is just a count of data points you'll be better off using a waveform graph instead of an XY Graph. Look at the help for graphs for more info.

Thanks guys. I think though luck is not what I primarily need but hard work instead

Excellent point! Although a little luck in landing the right contracts couldn't hurt.

Dear ExpressionFlow readers and fellow LabVIEW developers. I'm very excited to tell you, that recently I've founded a new Helsinki based company, Agile 4, providing LabVIEW software development related consultation services. Today, it's time to come out of the shadows and public with the company.

Congratulations Tomi! And best of luck :thumbup:

I am using XP.

Great I love these kind of problems... :headbang:

I confirmed that this doesn't work in XP with LV8.2 (that's all I had installed). What happens if you open this vi? It should look about like the screenshot I posted above, but with each character in its own comment/constant.

Edited to remove attachment

QUOTE (TobyD @ Feb 23 2009, 11:52 AM)

I pulled the attachment because it appears to have done some weird things...when I closed it, it crashed LV with this error:

When I relaunched LabVIEW, the other VI that I had opened looks like it has been converted to Japanese (the block diagram too)!!!

I don't have time to try to reproduce the issue now, but it looks like there might be a bug here somewhere. If you want to play with it AT YOUR OWN RISK here is the VI.

I tried that in LabVIEW 8.6.1 using the application font all I get is "F"

Hmm, not sure what is going on then. It works fine for me using the application font (LV 8.6 on windows vista).

I have found the Symbol font supports Greek Characters, however I need to have Greek and Latin letters in my text.

Have you tried the alt code for phi (alt+237 φ or alt+232 Φ). They both work in a string constant. If you're not familiar with alt codes, simply hold down the alt key and type the number combination on the keypad, then release the alt key.

My guess is homework, but here is the vi I used to solve #25 on project euler (modified to output the entire sequence as a 2D array instead of outputting only the term #. I was going to post it hoping it would get turned in as homework (because it is so pretty ). I'm too slow.
