How can I copy protect a Labview application?

We have a high value Labview 7.1 application that we want to copy protect. Are there any third party software solutions available that work with Labview and provide hardware locked copy protection? We want to prevent a single license key from being shared to allow installation of our application on multiple machines.
We looked into Software Passport / Armadillo but Software Passport does not support Labview. We would prefer to use a third party solution as opposed to coding something ourselves. We are not experienced with writing software security applications but if third party solutions are not available I guess we'll need to get our feet wet. Thanks.

I can imagine that a direct API implementation might be better.
My personal experience of such implemtnations has been that under these circumstances it is critical that: -
The implementation is solid.
Trust and security are correctly established.
It has been my experience that the above are quite difficult to assure. Where it works the EXE approach is probably better although the exposure to an attack by a sotware kit might be greater.
The above are why I indicated my alternate technique, not using a donlge but my own system. It is almost certainly weaker than a commercial implementation in some possibly many ways. But has the advantage that I change the implementation and techniques and whoever wants to access it has to start from zero. There are no kits because there aren't a million copies available.
I guess the right thing to do is to issue a challenge............perhaps with a reward........
But my experience of encryption is that it can always be broken by someone somwhere. The real questions are by who and when.

How can I run two independant LabView applications from the same computer, without taking a performance hit?

I have two identical, but independant test stations, both feeding data back to a Data Acquisition Computer running LabView 6.1. Everything is duplicated at the computer as well, with two E-series multifunction I/O cards (one for each test station) and two instances of the same LabView program for acquiring and analysing the data. The DAQ computer has a Celeron processor w/ 850Mhz clock and 512MB memory, and is running on Windows NT.
I have noticed that when I run both the applications simultaneously, I take a substantial performance hit in terms of processing speed (as opposed to running just one program). Why does this happen and how can I prevent it? (In t
his particular case, it may be possible to combine both the tests into one program since they are identical, but independant, simultaneous control of two different LabView programs is a concept I need to prove out).
Thanks in advance for any tips, hints and spoon feedings (!)....

Depending on your application, you may or may not be able to improve things.
Firstly, each task requires CPU time, so a certain performance difference is guaranteed. Making sure you have a "wait until ms" in every while loop helps in all but the most CPU intensive programs.
Secondly, if you are
1) streaming data to disk
2) Acquiring lots of data over the PCI bus
3) Sending lots of data o ver the network
you can have bottlenecks elsewhere than in your program (limited Disk, PCI or Network bandwidth).
Avoid also displaying data which doesn`t need to be displayed. An array indicator which only shows one element still needs a lot of processing time if the array itself is large.... Best is to set the indicator invisible if this is the case.
I think
it would be best if you could give some more information about the amount of data being acquired, processed and sent. Then maybe it will be more obvious where you can optimise things. If you are running W2000, try activating the task manager while the program(s) are sunning to see where the bottleneck is.

How can one copy/play a cd that seems to be protected

how can one copy/play a cd that seems to be protected. Is this always the case with compilation cd's? I cannot play, read or copy on my windows7 PC.

There are still many CDs around that are designed to make it difficult to rip, especially those from the Warner Brothers group.
Some that will not rip on a Windows machine will do OK on a Mac. If you have access to a Mac try it there, and bring the resulting MP3s back to your Windows machine on a flash drive so you can add them to your iTunes library.

How can i copy files from one external hard disk to another using macbook pro with retina display

How can i copy files from one external hard drive to another using macbook pro with retina display?

That's odd - if you open Disk Utility (Applications->Utilities) and select the disk(s), how are they formatted? If you're only going to be used with your Mac, they should be formatted as "Mac OS Extended (Journaled)".

I have copied my CDs into iTunes (currently running v11) to play on my iPod. I have now bought a non Apple mp3 player to use when I am out running. How can I copy the many tracks I want from iTunes onto the new player?

I have copied my CDs into iTunes (currently running v11) to play on my iPod. I have now bought a non Apple mp3 player to use when I am out running. How can I copy the many tracks I want from iTunes onto the new player?
Thanks

I tried Notpod but can't get it to work. Part of the problem, I suspect, is that I can't create a folder on my player (a SanDisk Clip+). I also can't do this in Windows Explorer. Whilst I can see the Clip+ in Explorer, the option to create a new folder isn't there.
The error mesag I get in Notpod is:
"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit the application will close immediately.
InvalidArgument=Value of '0' is not valid for 'SelctedIndex'. Parameter name: SelectedIndex"
Then, when I plug the Clip+ into a USB port, iTunes thinks it is my iPad - which is because, I guess, Notpod hasn't worked.
I can drag and drop files from the Music folder where my iTunes tracks are stored onto the Clip+ and they get converted but I'd rather synchronise a Playlist from iTunes if I can.
Thanks anyone who can help

How can I copy file/folders from and to hard drives? How can I have two or more windows of explorer so that I can drag and drop from one hard drive to another?

Hi,
I am a new customer (purchased last week) of MacBookPro (latest) and its my first ever Apple laptop.
I am almost lost to find the operating tools.
1. How can I copy files from hard drive to computer and vis-a-versa?
2. Only can browse one but how can I have two or more browses at the same time like in MS windows?
3. No right click works on track pad?
4. Is there application/ program compatible to MS office? If so how much and how can I purchase?
5. Is there AutoCAD program that is compatible to MS Window AutoCAD? and if yes how much and how can I purchase?
I will very much appreciate if you could email me the with the solution/answers please.
Regards,
Khagendra Limbu

1) For some reason this happens once in a while with FAT32 enabled external harddrives. I have no idea why this happens but it most easily solved by reformatting the drive. First make sure you've copied everything from the external drive to your internal harddrive. You've done this earlier so I assume you know how to do this.
Now the reformatting part. Open Finder and go to Applications. Look for the folder called "Utilities". Click on it. In it you find a program called "Disk Utility". Click on it. Now look for the external drive. You probably see two entries for the disk. Click on the one that contains the name of the drive NOT the one that describes the disk (Like for example 320.07 GB Samsung S2 Portable Media).
Now you see four tabs in the righthand part of the window. They're called "First Aid", "Erase", "RAID" and "Restore". Click on "Erase". This opens the tab with (amongst others) a dropdownbox (Format) and a textbox (Name) . In the dropdownbox select "Mac OS Extended (Journaled). Take note! This selection disables usage of the drive with Windows PC's. If your goal is to share the drive with Windows PC's select the MS-DOS FAT option.
Enter a label for the drive in the textbox Name. Now click on the button "Erase". This will format the drive.
Now when it's done you can copy back all the items you've copied to your internal harddrive earlier.
2) Opening two windows like Explorer on Windows is opening two Finder windows on the Mac. Simply click on the background. In the menubar you items like 'Finder", "File", "Edit", "View", et cetera. Click on "File" and "New Finder Window". Do this two times. Alternatively you can click on the background and press CMD-N two times.
3) You can right click on the trackpad. This however depends on if you've enabled the feature in System Preferences. In the topmenubar click on the Apple icon and select "System Preferences". Now look for Trackpad in Hardware. Click on it. You see three tabs with the names "Point & Click", "Scroll & Zoom" and "More Gestures". Select "Point & Click" and look for "Secondary Click'. Make sure it is checked and make sure it has written "Click or tap with two fingers" written beneath "Secondary Click". When you're done exit System Preferences. Now select the background and tap with two fingers on the trackpad. This should open the contextuel menu with options like "New Folder", "Get Info" et cetera.

How can i copy line with text and image to ms word

When I insert an image in textflow using InlineGraphicElement it works, but when I copy the line with the image to MS Word it copies only the text (not the image).
How can i copy the image to MS Word?

If you want copy formatted text and image to MS Word, you need to give MS Word rtf markup, because Word can recognize rtf markup but not TLF markup.
So you need to create a custom clipboard to paste a rtf markup. It's a large feature for you, because you need a tlf-rtf converter in your custom clipboard.
TLF Custom Clipboard Example:
package
    import flash.display.Sprite;
    import flash.desktop.ClipboardFormats;
    import flashx.textLayout.container.ContainerController;

    import flashx.textLayout.elements.*;
    import flashx.undo.UndoManager;
    // Example code to install a custom clipboard format. This one installs at the front of the list (overriding all later formats)
    // and adds a handler for plain text that strips out all consonants (everything except aeiou).
    public class CustomClipboardFormat extends Sprite
        public function CustomClipboardFormat()
            var textFlow:TextFlow = setup();
            TextConverter.addFormatAt(0, "vowelsOnly_extraList", VowelsOnlyImporter, AdditionalListExporter, "air:text" /* it's a converter for cliboard */);

How can I copy a list of email address into a group folder in contacts?

I have a list of all the email addresses of my tennis club members. How can I copy that into a group address. At the moment I have to find each one and drag it into the folder, but I am sure there must be an easier way. Does anyone know what that is?
Loftyjs

I'm glad you figured it out. I was thrown off by literally interpreting the term "list" I guess
In truth, a "mailing list" of multiple recipients, when applied to a particular email message is nothing more than a "comma de-limited list" of the addresses. Some mail clients add < > on either end of the individual addresses
[email protected],[email protected],[email protected],etc.
<[email protected]>,<[email protected]>,<[email protected]>,etc.
in the old days, we would just keep a text file an add to the end as needed.
lists are commonly used as 'Mini-databases' in Adobe(Macromedia) Director, my everyday tool for years. A list of lists, then becomes a bigger database as does a list of a (list of lists), and so on
Too much information, methinks

How can i copy and paste the list paragraph?

I uses the 'Pages' and have a problem to copy text to 'Mail' application from 'Pages'
The text with list like '1. blarblar' can't copy to other application with list format.
So the copy result is 'blarblar'. How can i copy the text with list styles?

I don't think the list style transfers. Copy and paste the text in to Mail, select it and then choose "Insert Numbered List" as a work around.

How can I copy/transfer iTunes content ?

How can I copy/transfer iTunes content from my old computer to the new one, considering that for some reason Target Mode and Migration Assistant doesn't work for me ?
I don't need the application itself (it comes with the new computer) but just the content.
I want to transfer my collection of CD in iTunes. they are all CD that I physically have in my living room, listen to them on my stereo and have copy them in my computer (which is in the Den) so I can listen while working on my computer.
The iTunes is version 9.0.2
Can I drag it to the external drive or perhaps just the songs, then copy/drag them to my new computer ?

Hi-
Can I drag it to the external drive or perhaps just the songs, then copy/drag them to my new computer ?
Pretty much, Yes.
If you wish to keep the formatting, notes, ratings, etc. that are with the library, you should allow the iTunes software to "discover" the library.
If the iTunes Library from one machine is placed on an external drive, the iTunes software on the other machine can be directed to the library of the external drive when connected.
Allowing "Copy to Home folder/music" will provide for copying of the library to the new machine.
Alternatively, if the library is loaded onto an iPod, the iPod can be used to transfer the music.
