Are there any advantages to using a Data Value Reference for LabVIEW Classes?

Hi
I recently came across an example where the developer had used a data value reference for the class cluster in LabVIEW.
What are the advantages of doing this?
Doesn't the use of LV objects already avoid the creation of multiple copies of data thereby reducting memory usage?
Thanks
AD

LabVIEW's OOP is implemented as a By Value. This means, as Tst stated, branches in wires could mean copies in the object. The DVR is a way to make it By Reference.

Are there any advantages of using Secure Empty Trash over regular Empty Trash?

Are there any advantages of using Secure Empty Trash over regular Empty Trash?

If you are going to run around with sensitive files on your file system, you might be better off using a whole disk encryption so that every file is encrypted, any deleted file contains encrypted contents. As long a no one can access your files using your encrytpion keys, all your data is secure.
Also secure delete is not really going to do much on a Solid State Drive, and again whole disk encryption would be a better choice.
For a moderate amount of data, secure erase does not take too much time. But if you have a ton of file and/or a few really large files to erase, secure erase can take a long time to complete as it is doing multiple pass to write and overwrite the file's storage with patterns of data that make it extremely difficult to recover the original data. That takes time.
Finally, if you have been updating a document, previous editions may have been given over to free storage as new versions are written, such that when you decide to erase the file you may only be doing secure erase on the most recent copy.

I'm buying a new computer for use with Creative Cloud. Are there any advantages to PC vs Mac?

I'm replacing a seven year old Dell that still works but is getting rather long in the tooth. I have CS4 web design. (For PC)
I have a Macbook Pro (so I'm familar with Mac OS)
I'm upgrading my computer to mainly use the Creative Cloud.
Are there any advantages (related to Creative Cloud) to buying a Mac or a PC?
I just don;t wan't to a Mac and then find that many features don;t work that are on the PC (or vice versa)
Or is one interface easier to use than another?
Thanks in advance for any help.

It usually boils down to personal preference.
The software is, to all intents and purposes, the same in either operating system. There are minor differences between them, usually related to the hardware or the operating system. But if you can use the software in Windows, you'll be able to use it on a Mac too.
It's a matter of which environment you prefer: Windows or Mac. I use both daily since the Cloud allows you to install on Windows and/or Mac.

JPA and CAF BO - are there any editors of the JPA data (like CAF)?

Hello!
As you know SAP invented some layer above JPA and called it CAF. There is a very convenient way to edit data in CAF.
But now I have to create a complex database scheme, also with CAF doesn't allow us to work with objects. So we can't use someObject.getChildren().
So my question is are there any editors of the JPA data (like it is done in CAF)?

Hi Kirill,
at the beginning of our project at the end of 2009, we did a deep analysis of CAF since our architect vehemently suggested to use this framework.
First about the history and purpose of CAF: Initially, CAF was never meant to be a layer above CAF since CAF was invented in the time before EJB 3.0 and JPA standard where writing persistence with EJB 2.x CMP forced the developer to write pages of boiler plate code. This background was approved by SAP.
With upcoming of JPA, CAF ist mostly useless (except for very simply structured data) and prevents you from writing good software.
It is easy just to write @Entity, @Id and @OneToMany (for complex database schemes) and CAF forces you to use an ugly, imperformant database scheme (e.g. CAF uses mapping tables even for 1:n relationships, a clear antipattern!)
The CRUD-services generated with CAF are a pain, too. Usage of pessimistic locking is not up to date for web applications.
With your complex database schemes, you exceed the limit of CAF.
(We decided not to use CAF and did never regret this.)
Concerning your question: There is an "JPA Details" view in NWDS that might help you. It needs JPA Persistence facet on your project to work. Developed by SAP. For JPA beginners, it is a good cheat sheet for JPA annotations and their attributes.
You do not need more since a JPA POJO is easy to code.
Regards,
Rolf

Is there any advantage to use database helper class

Is there any advantage to use database helper class ( e.g. database.bookDB in Duke's bookstore)in servlet design? What if I setup a DB connection for every servlet?

If there is not much relation between servlets.For example one servlet working on authentication againist user name/password in database another one work on searching book by keywords?
and if we want to have servlets written by difference programmers?

AVCD on MAC: are there any processing problems using say, VLC?

AVCD on MAC: are there any processing problems using say, VLC?

We've actually found that the Server 10.6.3 DVD does an amazingly smooth job of upgrading 10.5.8. We've been upgrading our production servers and nothing has gone wrong yet. Snow Leopard employs an archive and install method of upgrading which results in an install which is very close to a clean install. So it's been very convenient for us because our servers are used as Windows PDCs and it's a pain in the *** to have to re-join all PCs to the domain if we start from scratch.

Is there any constrain in using the same order type for MTS and MTO

Hi,
i have the constrain to use single production order type .
Can i use single order type for MTO and MTS.
is there any constrain in using the same order type for MTS and MTO.
pls help me.

Hi,
There is no constraint or limitation in using the same production order type for MTS and MTO . Settings in requirement class and material master will mainly control whether the flow is MTS or MTO.

HT201342 Are there any setting or some way to show notifications for new email without open Apple Mail app ?

Are there any setting or some way to show notifications for new email without open Apple Mail app ?
You know , I am an OCD . I alway's close my Mail app and miss many important new emails .

What I do is open the Mail.app, then click the red traffic light (upper left corner of the main Mail.app window) to close that window. The app itself will remain running and you will get updates - this helps keep the desktop tidy while while the mail app remains running. When an update is received, simply click the either the mail icon in your dock or go to the Mail.app menu and click Window > Message Viewer.

Are there any risks to use native sql in ABAP to access external DB

here is a requirement to use native sql in abap program to access external DB to load some data into sap. Are there any risks and effects which SAP not recommend ?
Can anybody show some official document to me because I want to know some risks and dangerous to report to my manager..thanks very much.

hi Anversha s
thank you for your reply
I means what's the risk when to use native sql to access external DB..
can you show me some examples about open sql which is used to access external DB...
Now I am investigating the technique about the connection
between SAP (by abap program) and external DB...the supporter suggestion is to use native sql to access external DBs.but my manager is afraid of the risks when to use native sql,So I have to report the effective document (example: SAP official document) to explain to my manager.
thanks very much

Are there any issues when using AirPlay on an Apple TV that is using a shared internet connection?

I am currently in a hotel and I have my MacBook Pro, iPad, and Apple TV (2nd gen). The hotel I'm in has both wired and wireless internet connections. I cannot directly connect my Apple TV to either connection because the hotel connections require you to agree to some terms and conditions that the Apple TV can't access. To further complicate things the ethernet connection in my room doesn't work at all. So the solution I found to at least connect the Apple TV to the internet was this: using my MacBook Pro, I connected to the hotel wireless connection (to bypass the hotel internet's T&C). I then shared that wireless connection via ethernet to the Apple TV. It works. I can watch YouTube and Netflix but I can't take advantage of AirPlay. I've updated, restored, and reset the Apple TV numerous times, but no luck. Are there any settings or connections I'm missing?

Airplay from what? iTunes or iPad?
I assume iPad - in this setup the iPad and AppleTv will be unlikely to be able to see each other on the hotel network even if both are connected wirelessly. If they can and you don't have a user/room specific login I'd be concerned about other users seeing my devices too. These things are generally designed for single user access not to create your own local network. I suspect in the T&Cs for the wi-fi service it may preclude sharing the internet connection with another device, but if it works....

Hi,
Can any one let me know if i can create a customer using BAPI with personal data and with out any reference customer number. If i create with reference number the partner functions are picked up from here while creating the new customer.
Thanks in advance.

Question: Are there any advantages for stored procedure for data block?

There are two ways to create data block:
1. query table or view or
2. stored procedure.
After 9i, AS has a PL/SQL compiler. Do we still see the advantage of using stored procedure, as claimed that it is faster due to the stored procedure always compiled?
Thank you in advance.
Jimmy

Jimmy,
The "fast" side is not the only one benefit of stored procedures.
Of course, you can use the BULK COLLECT functionality which is not available into Forms.
But stored procedure is a good way to perform the following actions:
complex handeling of datas (insert, update or delete that generate severals actions on other tables).
externalization/centralisation of business rules.(separate the design and functionnal work).
more secutity, because you can prohibit manipulation of datas outside of the procedures.
You can change the rules without modify the forms.
etc.

Are there any differences between using Adobe Illustrator on a MAC and on a PC?

Hello,
I'm about go enroll in a class specialized for teaching Adobe Illustrator in order to be able to use the program at work. The company that I work at uses Macintosh computers to deal with clerical work and everything, so I would like to know if there are any differences between using Adobe Ilustrator on a MAC and on a PC. The school that offers training teaches two types of classes, where one uses Illustrator on a MAC, and the other one on a PC. The PC class is able to have an earlier start date, which is why I'm sort of leaning towards choosing that class as I need to be able to use the software as soon as possible, but if there are main differences between the interface that will affect my knowledge of using Illustrator on a MAC after I take the class with Windows systems, then I will most likely be waiting for the class teaching in MAC systems.
Thanks in advance for the help!
Oh and another suggestion- should I take the Illustrator class in CS6 or CS5?

Reading through the CS5 vs CS6 performance thread, the Mac version seems to have worse performance than Windows version. From a starter's perspective the differences would most likely never be realized. It will take some time to see differences between even CS5 and CS6 other than the visual aspect of course.
Definitely take the CS6 versionso you can say you have it. CS5 is my preferred version, CS6 is garbage with the bugs it has for the type of work I use it for.

Is there any advantage in using Vault over Time Machine?

Hi all,
Yesterday I imported around 6000+ pictures from iPhoto and consolidated them into my Aperture library. After much re-organisation into projects, folders etc. I decided to update my backup Vault to preserve all my hard work. The Vault is located on a connected external drive with plenty of spare storage. I had previously backed up successfully to the vault when there was only a few dozen pictures in my library.
After initiating the Vault update process I then left it to get on it (and to have dinner and then watch the football...) and after several hours was dismayed to find that the process appeared to be stuck at just over 50% completion. It was obvious that no further progress was being made.
I was also concerned that there appeared to be no mechanism to cancel the process and the only course of action I could take was to apply a Force Quit against Aperture - not something that I care to do, if I can possibly avoid it.
After a rudimentary search of this community I saw that several others had experienced the same problem - although some suggested that a fix had been applied in recent versions (although I am running the latest version).
Given this, I'm reluctant to use the Vault again - particularly as there appears to be no means of cancelling a stuck job. I do however use Time Machine, so my questions are:
1) Do I really need to use Vault if I have Time Machine making regular backups of my Aperture library to an external drive?
2) Does using Vault give any advantages over Time Machine?
3) Is anyone else experiencing this problem with the current version of Aperture (v3.3)?
4) Is there anyway of cancelling a stuck Vault update other than the sledgehammer approach of Force Quit?
Thanks in anticipation,
Simon.

SImon,
Vault and Time Machine address different needs. Probably you will want to have both.
The advantage of Time Machine: incremental backups of previous versions, very compact storage. And you can integrate it into your regular backup of the whole system and include the regular masters as well. But the disadvantage: Time Machine decides for you, what will be deleted, if the backup drives get full. You do not have control over what will be saved and what not from the previous versions.
The advantage of vaults: You can make full backups of your library for well defined moments in time - snapshots of important states. I'd create a vault, whenever I make a major upgrade of the system at least.
Is there anyway of cancelling a stuck Vault update other than the sledgehammer approach of Force Quit?
If the graphical user interface is unresponsive, like when updating a vault, you can use the Terminal to send the "termination signal" to Aperture: Sometimes this will succeed, even if the "Quit" button does not work:
Look for the Process ID of Aperture in the Activity Monitor (launch Applications > Utilities > Activity Monitor" and click the CPU heading. This will bring Aperture close to the top of the list. Make a note of the PID number in the first column, in this case 66550.
Launch a Terminal window and enter the following command:
kill -TERM 66550 (insert Aperture's PID instead of 66550)
This will send the "Software Termination Signal - TERM to Aperture, the same as pressing the "Quit" button should do, but send it directly, and not from the GUI that is unresponsive. This way I always succeded in cancelling a vaul update without force quitting. Not all processes can be terminated this way, however. The Terminal.app is also in the Applications > Utilities folder.

Léonie
