How long did this take you? My advice is keep it simple and get it done. Clean code with good documentation. Clever will waste your time and leave you with an incomplete project that isn't fully documented.

One quick comment, the "Standard State Machine.vi" has a three deep case structure in the "Update" case. Use the "select" function in the comparison palellete for a cleaner and more readable vi.

What were you using that required that dll? Some scan engine related VI? Did you have real-time installed? I'm trying to figure out how you got into this situation so that perhaps I can fix it.

thanks,

greg

No LVRT. I have DevSuite installed with LabVIEW 8.6 PDS. I never figured out what the culprit was. I sent code into NI that was causing the problem, but due to some organizational issues on my part the submission was incomplete. By the time I got my code structure fixed, I figured that NI had the problem corrected. What do you mean by scan engine?

I had the same error, but it was fatal for my build. Same solution as yours.

This post is to follow up from http://forums.lavag.org/-t11544.html&view=findpost&p=55706' target="_blank">here where I reported that NIScanEngine\nilvce.dll couldn't be found during a build I was attempting. It was a non fatal error as the exe still built.

NI gave me a solution by suppyling me with the missing directory and files (zipped up) which you install to here

C:\Program Files\National Instruments\LabVIEW 8.6\vi.lib\NIScanEngine\

Unless NI have posted these files on their website, please contact ni.com/ask and ask for the application engineer to send you a copy of NIScanEngine.zip

I did a couple small projects using labview every year , so I am not at a professional level even using it for 6 yrs.

The CLAD is supposed to show that you have a good understanding of the basics of LabVIEW and the CLD shows that you are at a professional level. Don't waste your money on the exams until your LabVIEW knowledge matches the exam. You should concentrate on learning the concepts to pass the CLAD first. LabVIEW for Everyone is a good place to start.

Be on the lookout for the NI seminars. There is usually one in the spring and the last two years they have given out $200 certificates towards training or certification. Have you looked for a LabVIEW users group in your area or spoken with your local NI sales representative? These can be good sources of assistance.

There aren't any CLAD/CLD manuals that I know of. The best things to study are the guides that NI provides for free online. Are you refering to the LabVIEW course books?

Are your SubVI's part of your GUI? Do you want them to show on your front panel or open when called? Or, are they simply not returning the expected results when placed in your main VI.

QUOTE (Sonic_Soul @ Nov 12 2008, 05:35 AM)

Hi,

I've got quite a few working VI's now... and I'd like to add them as a Sub VI's to a larger VI which is basically a user interface. I know how to access the icon pane and connect my inputs and outputs to the terminals but whenever I insert any of these VI's into the user interface VI they never work! They all work stand-alone, but not when incorporated into the interface VI. Why would this be?

Thanks.

Hello,

I know this info is somewhere but I am having a hard time trying to find it.

When using a Counter/timer to measure frequency there are multiple methods.

i.e. Low Frequency with 1 counter and high frequency with 2 counters.

What is the definition of a "low frequency" and what is the definition of a "high frequency"? i.e. low frequency = frequencies below 100 Hz

Also what is the definition of a "large range"?

Thanks

Dan

How many bit is the counter and how often will you be reading it? If there is a possibility of rollover, you will need two CTRs otherwise one will suffice. But, this only matters if you need to count every pulse. (No political comments please ) If you are just measuring frequency and duty cycle this shouldn't be an issue.

How can I retrieve computer id of my system in Labview, programatically.

What kind of ID are you looking for? Do you want the computer name or some kind of serial number? What OS are you using? The answer is likely to be OS specific.

From: Minister of the Treasury Paulson

Subject: Request for urgent confidential business relationship

Dear American: I need to ask you to support an urgent secret business relationship with a transfer of funds of great magnitude. I am minister of the Treasury of the Republic of America. My country has had crisis that has caused the need for large transfer of funds of US$700bn. If you would assist me in this transfer, it would be most profitable to you. This transaction is 100 per cent safe. This is a matter of great urgency. We need a blank check. We need the funds as quickly as possible. My family lawyer advised me that I should look for a reliable and trustworthy person who will act as next of kin so the funds can be transferred. Please reply with all of your bank account, IRA and college fund account numbers and those of your children and grandchildren to wallstreetbailout@treasury.gov so that we may transfer your commission for this transaction. After I receive that information I will respond with detailed information about safeguards that will be used to protect the funds.

Yours faithfully,

Minister of Treasury Paulson, Nigeria, Washington DC

I really need this feature

What you are showing are child windows. LabVIEW does not natively support child windows, but you can create them through Windows OS calls. See this http://forums.lavag.org/Simulating-MDI-interface-in-Labview-t1071.html' target="_blank">LAVA thread for more information.

I would highly recommend that you look at alternatives such as tab controls and subpanels before attempting child windows in LabVIEW.

I seem to remember that the built in symbols were accessible just like the custom symbols, but with indexes of 0-39 (0 being blank)..as long as you didn't over-write them with your own symbols at runtime. Is this not the case?

See http://digital.ni.com/public.nsf/allkb/89A75D98771F2FB686256F350055EB3A' target="_blank">here.

Custom symbols in Tree controls and MCLs? And this feature has been in LabVIEW since 8.0? How did I miss this feature?

QUOTE (george seifert @ Sep 17 2008, 08:31 AM)

That's what I meant. I believe it works for things other than Word, but I understand not wanting to use non-standard updates. I don't know of another good way to get around it. I agree that NI didn't handle this update right.

George

As written the hacked "Get Report Type.vi" outputs a "Word._Document" reference. It is relativily simple to update the 5 VIs to an Excel reference (hack the hack!).

Can't get Word.Tables in Report Generation Toolkit in LV 8.6

George

Are you refering to http://digital.ni.com/public.nsf/allkb/8D2F46628809472F862574B000534AF5' target="_blank">Getting References in Report Generation Toolkit 1.1.3 with LabVIEW 8.6? This set of VIs give access to the report reference through a hack of "Get Report Type". There are a two problems with this solution: non-standard update of the toolkit/vi.lib and it only works for Word reports. I am using Excel and I don't want to have to worry about LabVIEW updates.

Who's bright idea was it to update the Report Generation Toolkit to LVOOP?

To extend the old toolkit, I could grab a reference to the report (Generate Report Get Data to Modify.vi) and call whatever MS-Office methods and properties I needed. How do I add features to the new toolkit without changing vi.lib?

QUOTE (Cyclothymia @ Jul 30 2008, 08:15 AM)

It worked fine, as long as the file was still open, so I saved and quit.

HOWEVER, when I restarted LabVIEW again and ran the same program, it stopped working and generated error 1097:

Is the dll in the same directory as your vi? Is the path set correctly in the call library node?

I did something very similar a few years ago - I stopped trying to support my own editor and started using TestStand

I don't think so. TestStand 4.0 was released in April 2007 and it was the first version of TestStand with undo. I actually implemented my undo command a months earlier. My newest feature is a syntax checker.

QUOTE (crelf @ Jun 4 2008, 03:37 PM)

No undo actually made me cry once...

Yeah, there was nothing like an accidental control drag in a 20 deep case structure to make you want to hurt an NI engineer.

I've recently implemented "undo" into the sequence editor of my test executive. After living without undo in LabVIEW for so many years, this should have been an obvious feature to add, but it was a user request, not my own idea.
