A thought on Style for the sake of Style, and a question: Where to wire constants?

Lately, I've been trying to hone in on aspects of Style that effect my program's performance, and ignoring stylistic niceties in the sake of meeting deadlines. For example, Local Variables: if they work and don't cause race conditions, what the hey? I used to break my back to use as few locals as possible, but after Profiling some vi's, I've found I can live with 50mS delay here and there. Same for the "one page diagram" idea. Most of my programs take up two screens, while still using several sub-vi's! I've even gone back to using sequences after swearing them off a year ago. Where's the break-even point of using excellent Style and keeping your job?
Now for a question that I can't s
eem to profile my way into an answer::
Most of my programs run in one large loop and use Cases to run events. Many items require constants. Does it make much difference to place these constants OUTSIDE the loop? I'm assuming a constant of 12093.0092 may take more time and memory than, say a boolean True constant or a Not A Path constant. Any thoughts?

Hello. In regard to the first part of your question, it's very important to remain productive and meet all of your deadlines. You can maintain good style and obtain efficient performance and improve your productivity by following some simple guidelines. One such guideline is to use a state machine architecture for most of your top level diagrams. With a state machine, you can avoid local variables by passing data in shift registers, and reading or modifying the data within the appropriate states (frames of the case structure). You also conserve block diagram space by breaking your application into snippets that each fit within one frame of your case structure. Best of all, you can easily expand your application as needed by simply adding more frames to the
case structure and enumerated type definition.
To quickly create a state machine using LabVIEW 7.0, choose the Standard State Machine Template from the New... dialog, under Design Patterns.

Does anyone know if the new iPad fits the Powersupport screen protector for the iPad 2? And if so, where can I get it installed?

Hey, I was just wondering because I am purchasing my New iPad on Sunday! So excited! But I want to order a screen protector before I go and purchase it. I heard you could get screen protectors installed at Best Buy, but I'm not sure!! Please help!

I just got the powersupport crystal fil for the iPad2 and installed it on my new iPad (3rd gen). It fits perfectly and so far it doesn't affect anything (proximity, portrait/landscape rotation). in my opinion it's the best screen protector for the iPhone so naturally I thought i'd give it a go on the iPad (no adhesive, easy install, great quality etc). One note though, I'm not sure if the anti-glare one would work well on the new iPad with the retina display. I know the iPhone 4 uses a different one than the 3GS. Oh and Best Buy doesn't sell the powersupport.

How to define the style for JTextArea using synth style xml file.

Hi all,
How can we align the text inside the JTextArea using synth style xml file.
We defined a style for the TextArea. But the text is displayed immediately after the border. So we want to provide some space between the border and the text.We specified the insets as given below. But it is not reflecting during runtime.
<insets top="3" left="3" bottom="3" right="3"/>
Please help me if any one knows

Hello everybody,
(I'm using APEX 3.2)
I get a really annoying problem. I'm using report region to show the selected options in one of my application. When I'm creating or editing that content, I do it in a specialised page. To edit my content, I'm using a standard edit button link in my first column. But the button column is ALWAYS taking too much space in my report, it shouldn't be longer then 30 pixels wide. I 'm trying to use the attribute fields or table attribute fields with style="width:30px;" but it never works. I'm having a hard time following this (and I don't currently have access to 3.2). Although its a different version, suggest you create a similar example on apex.oracle.com to give a clearer idea of the situation.
The only way I found to do that was by creating a new template and write my new style in the header option. But I was told that I can't edit those tamplate. What template? Who told you this?
I'm thinking that some substitution strings are missing and that is why it changes nothing.What substitution strings?
It always helps if you provide precise details of:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s)

when you play the CD in your laptop on your home screen a Cd should pop up under the name of the album. Than when you open itunes it will probly say something like "let this CD download" or something like that. If it doesn't than automaticlly while the CD is importing to your itunes a page will pop up with a progess of the CD download.
Hope that helped.

Is there a stylus with a nib for the iPad...and an app that goes with it?

Is there a stylus available for the ipad that looks and feels like a pen? I asked the question on the highstreet the other day and was shown a stylus that was as thick as my finger!!! (I think it was made by a company called Genius?). I am used to using an IBM tablet pc which comes with a stylus that can write in quite fine lines- can this be done on the iPad? Also if the answer is yes, I'd like to know if there is an application similar to Windows journal whereby you can save notes into your own file structure? Can anyone help- surely these are basic things for a tablet pc- I don't know why the folks on the highstreet can't help confirm this??? Thank you

The iPad screen uses a different technology to the tablet PC to which you refer and any 'stylus' needs to have sufficient width and to be able to transmit an electrical current. That's why the styli for iPads are usually thick and made from a 'sponge' like material.
You could try http://www.beststylus.com/ I have one of theirs on order but haven't received it yet. The videos look encouraging, but you'll never get the thin line experience of the tablet PC. (On the other hand you couldn't really use your finger as a stylus on the tablet; different ideas about input).
On the app side you may want to look at Note Taker Hd (works quite well without a stylus) and Mental Note (this is what I'm hoping the stylus will help with).

I am in the process of expanding a database of chemistry journal articles. These materials are ideally acquired in two formats when both are available-- PDF and HTML. To oversimplify, PDFs are for the user to read, and derivatives of the HTML versions are for the computer to read. Both formats are, of course, readily recognized and indexed by Spotlight. Journal articles have two essential components with regards to a database: the topical content of the article itself, and the cited references to other scientific literature. While a PDF merely lists these references, the HTML version has, in addition, links to the cited items. Each link URL contains the digital object identifier (doi) for the item it points to. A doi is a unique string that points to one and only one object, and can be quite useful if rendered in a manner that enables indexing by Spotlight. Embedded URL's are, of course, ignored by Spotlight. As a result, HTML-formatted articles must be processed so that URL's are openly displayed as readable text before Spotlight will recognize them. Conversion to DOC format using MS Word, followed by conversion to RTF using Text Edit accomplishes this, but is quite labor intensive.
In the last few months, I have added about 3,500 articles to this collection, which means that any procedure for rendering URL's must be automated and able to process large batches of documents with minimal user oversight. This procedure needs to generate a separate file for each HTML document processed. Trials using Automator's "Get Specified Finder Items" and "Get Selected Finder Items", as well as "Ask For Finder Items" (along with "Get URLs From Web Pages") give unsatisfactory results. When provided with multiple input documents, these three commands generate output in which the URLs from multiple input items are merged into a single block, which yields a single file using "Create New Word Document" as the subsequent step. A one-to-one, input file to output file result can be obtained by processing one file at a time, but this requires manual selection of each item and one-at-a-time processing. What I need is a command that accepts multiple input documents, but processes them one at a time, generating a separate output for each file processed. Is there a way for Automator to do this?

Hi,
With the project all done, i'm preparing for the presentation. Managed to get my hands on a HD beamer for the night (Epason TW2000) and planning to do the presentation in HD.
That of course managed to bring up some problems. I posted a thread which i'll repost here . Sorry for the repost, i normally do not intend to do this, but since this thread is actually about the same thing, i'd like to ask the same question to you. The end version is in AfterEffects, but that actually doesn't alter the question. It's about export:
"I want to export my AE project of approx 30 min containing several HD files to a Blu Ray disc. The end goal is to project the video in HD quality using the Epson EMP-TW2000 projector. This projector is HD compatible.
To project the video I need to connect the beamer to a computer capable of playing a heavy HD file (1), OR burn the project to a BRD (2) and play it using a BRplayer.
I prefer option 2, so my question is: which would be the preferred export preset?
Project specs:
                    - 1920x1080 sq pix (16:9)
                    - 25 fps
                    - my imported video files (Prem.Pro sequences) are also 25 fps and are Progressive (!)
To export to a BRD compatible format, do i not encounter a big problem: my projectfiles are 25 fps and progressive, and I believe that the only Bluray preset dispaying 1920x1080 with 25 fps requests an INTERLACED video (I viewed the presets found on this forum, this thread)... There is also a Progr. format, BUT then you need 30 fps (29,...).
So, is there one dimension that can be changed without changing the content of the video, and if yes which one (either the interlacing or the fps).
I'm not very familiar with the whole Blu-ray thing, I hope that someone can help me out."
Please give it a look.
Thanks,
Jef

My 4th generation iPod Touch won't let me get on to the App Store. When I log on to iTunes, an alert pops up that says the certificate for the server is invalid, and that it may be a server pretending to be iTunes. What should I do?

My iPod won't let me on to the App Store, and whenever I go on to ITunes, an alert pops up that the certificate for the server is invalid, and that I may be connecting to a server that is only pretending to be iTunes.apple.com and my personal info may be at risk. I downloaded an emulator yesterday from coolroms.com but deleted the app this afternoon. I cleared my safari search data, my cookies and data, and web inspector, which still didn't work. I then proceeded to reset my iPod and then download the newest version of IOS 6.1.5 but yet still am having problems. Also to the App Store and iTunes, several other apps aren't working. Any help here?

Also, when I go on to safari, another alert pops up that safari cannot verify the identity of the website, anything that I type in to as common as google.com. It gives me 3 options to either cancel, look at details, and continue. I've looked at the details of the website of Google and it is legitimate the site. Any help?

Probably the best place to start is the right forum for your product. This is the forum for Distiller Server, a long dead product used by big companies, and probably not what you have. If you can't find the right forum, please let us know the FULL name of what you paid for (please check your invoice, as Adobe have many similar products), and we can perhaps direct you. Good luck!

This was thosands of songs that I had carefully picked over the years and now they are all gone. Someone please help me!!!

Get all that music back in itunes and sync again.

My Adobe trial for Photoshop Elements 10 for the Mac was over and I wanted to buy the application. The screen message was "Your trial has expired...but the fun doesn't have to end! Buy now to continue using Photoshop Elements 10 without having to download or re-install. " and then the button "Buy Now". When I hit the Buy Now button I am put in a field to buy Photoshop Elements 13, with no way to change to Elements 10. I do not want to go through the hassle of reinstalling etc. In fairness, it's been over a month since making the decision to buy. Still, I consider this a nightmare. Any ideas on how to buy the app I've got withou having to purchase a whole new one? Thanks.
If worse comes to worse, will I need to uninstall the trial if I buy a new version? Can I use part of it lime download assistant?

Adobe does not sell older versions of their software. If you wish to purchase an older version you will have to find and take your chances with a third party vendor.
