I want to know it too. If you change your wating from 1 ms multiple to 0, the loop will iterate much more fast, but your CPU load goes to 100%. Why LV doesn't have an NOP operator?

Eugen

Hello,

I wonder why LV doesn't get acceptance by other programmer. The most of people are sceptic if I say LV is assimilable to other programming languages. I find LV is very great and makes some things easier.

Why to drive bike if there are motorbike.

Greetings, Eugen

Start edit the palette ( menu Tools->Advanced->Edit Palettes... )

Add VI(s) to the palette by right-clicking on the area where you want them (Insert -> VI(s)...)

When a VI has been added, right click on the ICON and select Merge VI

Save your palette.

Next time you select this VI from the palette, it will insert a piece of code on your BD and controls/indicators to your FP.

Oh thanks, it works. I find it very usefull. :thumbup:

How can I create template like this?

Thanks, save for previous version in LV includes all depencies automaticaly only if i select a folder in the save dialog. But the VI from ars_stowers is very interesting.

Thanks a lot, Eugen

Sorry, I think I start my VIs dynamicaly, and they are not included if I save for previous.

Eugen

QUOTE(JFM @ Feb 23 2007, 06:28 PM)

I'm not sure what you mean, but you can select your top VI and save that for a previous version. All linked VIs (except those in vi.lib) will also be saved for previous.

Is this what you need?

Is it not posible??? Must I open every VI (of 30) and save they for previous version? What would be if I would have 500 VIs?

Hello, is it possible to convert all of my project VIs including depencies and all of files to previous version?

I have 8.0.1 and want to convert and distribute for 7.1.

Thanks, Eugen

Try this VI. It uses the Variant Data Tools to recurse into any structure and swap endianess of numbers

Yes, I am happy now. Thanks a lot. :thumbup:

Eugen

No more ideas?

QUOTE(JFM @ Feb 22 2007, 05:18 PM)

If you want to change the byte order in a DBL (e.g. to Little Endian byte order), you can always typecast to an array of U8.

For Little Endian, just reverse this array and typecast back to DBL

Oh, thanks, but I want to handle any data undependent on type. So I want to replace Flatten To String with my own VI, that has the same functionality and works under 7.x versions.

The problem is, I have a lot of big clusters with different datas, so I don't want to handle every element others, I want only one VI, that converts every data type.

Eugen

Hi,

Flatten to string and friends are independent of machine type. So you can use the same data on both Macs and PC's. Flatten/unflatten does the big/little endian rearranging for you.

Joris

Thanks, I know, but this feature for this VI is only available for 8.x versions. I can't convert data from big endian to little endian in 7.x.

Hello, my question is:

how can I realize Flatten To String with little endian byte order for 7.x LabVIEW versions? I tryed Swap Bytes and Type Cast VIs, but it fits only interegr data types and not floating point numbers.

Eugen

Hello, it's possible to built the LV Runtime and used DLLs into Executable similar to MS Visual Studio? I think so, i don't should to install my application, only start the exe and it runs. However the EXE gets a big size.

Eugen

Oh, it's very interesting and new(for me) information.

Thanks, Eugen

Hello Eugen

I would suggest you to Implement a "time-protection" or something. But the most important thing is that you don't make just a subvi with an output (true/false) you have to think a bit more and create a complicatted string (numbers)...

Otherwise someone could easy change your protection-vi with a self made vi...

(You can also check the call chain etc. to prevent such things...)

But I think the best thing is to implement such a "check" directly in your vi and not in a subvi...

Theoretically someone could easy change the date on his computer, but there are also ways to prevent (dedect) this...

I think an executable can't be changed :thumbup: easy replacing a SubVI.

Thanks, it does.

Eugen

Hello,

can anybody say why in the functions palette are empty places? How to get this away?

ZITAT(Omar Mussa @ Feb 10 2007, 12:06 AM)

There are third party tools you can buy off the shelf that make it fairly easy to implement time expirations and other feature locks.

The easiest way to do this is to Google "software copy protection" and you'll find a lot of tools.

I've used some software by http://www.sampson-multimedia.com' target="_blank">Crypto - I've not been terribly impressed by it but it is the reason I know such software exists. Most likely, the tool will come in the form of a dll.

Thanks :-)

Don't forget the LV-Diff. You can see all of differences in old and new version. You can built it in TSVN.

Eugen

It really depends! If you want to make an executable anyhow just build in some timecheck after which the application will refuse to run. Will obligate you to regularly create new trial executables.

If you want to distribute trial libraries do the same in some essential VI that one has to use and make it display a dialog too. Password protect that VI.

Any other means is probably more hassle than worth to do.

In any case be prepared that a few people will download your software but you probably won't sell much. It is already hard to get a lot of people to use free Open Source libraries!

Rolf Kalbermatter

To the last: It's a challenge from my employer.

I want to make an executable, that runs only 1 month. I think on MAC-Adress and Date formatted, that is ciphed and added in windows registry.

Eugen

No Ideas?

Hello,

how can I create a trial version of my executable? Are there any tools from NI?

Grtx, Eugen

In cases if I must save configs such Front Panel or Settings Cluster I use XML-Files without any converting troubles.

Eugen

So, thanks for answers.

I hope I found out the problem. TSVN checks all changes in all windows files (recursively) which deals something which version controlled files(incl. Windows Temp Directrory). May happen that TSVN and LV want to open or change the same file simultaneously and here it crashes. To avoid this, change settings in Tortoise options shown on the picture (so set from "standard" to "shell"). I found it out using Filemon Tool, which shows all events in windows (which file on which time was opened, changes and so on).

Regards, Eugen
