Questions on working with ApplicationObjects

Based on the embedded attribute example in the iFS developer's guide, and various discussion threads (in particular http://technet.oracle.com:89/ubb/Forum36/HTML/000184.html, responses by Mark Drake) I have created a custom class which subclasses the Document class. Call this the 'MyDocument' class. The MyDocument class has been defined to contain another custom class which subclasses the ApplicationObject Class. Call this the 'MyAppObject' class. The MyAppObject class has been defined to contain a number of attributes.
Thus the XML to create an instance of MyDocument might look like:
<MyDocument>
<Name>
My Document First Instance
</Name>
<MyAppObject>
<Name>
First MyAppObject Instance
</Name>
<Attr1>
xxx
</Attr1>
<Attr2>
yyy
</Attr2>
<Attrn>
zzz
</Attrn>
</MyAppObject>
<MyDocument>
After loading this document, I view its properties via the WebUI and see:
Class Name: DOCUMENT
Name: My Document First Instance
MyAppObject: First MyAppObject Instance
QUESTION: Is there anyway within the WebUI to drill down to see the attributes of the application object that makes up this document type? Must I write custom JSP to view these attributes?
According to the information the discussion thread cited above, I should be able to create a second instance of MyDocument which uses a reference to the existing instance of MyAppObject ("First MyAppObject Instance"). I tried to do this using the example in the thread as a guideline, but was unsuccessful.
QUESTION: How to create MyDocument instance using a reference to existing MyAppObject? Please provide some working code example.
Finally, when I delete the instance of MyDocument, "My Document First Instance", the MyAppObject instance, "First MyAppObject Instance", remains. This can be seen by querying the ODMV_MYAPPOBJECT view in IFSSYS.
QUESTION: How do I delete application object instances? I tried using an XML file with a DELETE attribute similar to the UPDATE attribute for updating custom attributes, but that did not work ("Parser Syntax Error (DELETE)"). (Note: using <UPDATE reftype=name> on the application object DID work.)
Thank you for your consideration.

Hi,
is possible callmanager works with etherchannel?

I don't think so, but even if it does, what would the benefit ?
You can have a regular dual-NIC config for redundancy.

Question about working with an audio interface

Hi
I just bought an audio interface (tascam us-122l) and i have logic express 8 installed, so i've connected my guitar and my keyboard (via MIDI) to the audio interface, and i've read the user's manual but i still don't know how things work...
Is it possible to use the built-in speakers on my imac as a sort of "amplifier". So when i play on my guitar or keyboard, i can hear what i'm playing trough my imac.
This is what i did so far;
- installed the drivers and updated the firmware
- system preferences > sound > input and clicked on my audio interface (US-122L)
- LE8 > preferences > audio > devices > and i selected the US-122L as device
This might be a stupid question but i just want to record songs.
Thnx anyway.

Logic audio preferences assumes you want to use your interface as an output for monitor speakers - the standard way and the best way given that your internal spekers will be neither loud enough or good enough to act as great monitors. If you don't have speakers you will be able to hear what you have recorded through headphones connected to your interface. If you want to listen from imac speakers or audio out you do indeed need to change to "built in input" - this is just a name logic uses to refer to your imacs internal sound card (including input and output).
To separate the input and output for different devices you need to set up your aggregate device, which you should be able to do, though you say you can't.

Working with iPhoto pix in iMovie '11

Two questions on working with iPhoto pictures in iMovie '11:
Is there a way to control the sort order of pictures in an iPhoto event in iMovie '11? Or, looking at it from a different perspective, how does iMovie '11 sort photos when I'm browsing an iPhoto event? iMovie has the photos in a different order than iMovie and I can't figure out how it's determinig sort order. I'd like the photos in iMovie to use the same sort order that iPhoto uses. The next best option would be to have iMovie sort by photo name. Just as background, the sort order I set in iPhoto is "By Title." Before import into iPhoto, I changed the titles of some photos that I know will not be used in iMovie so that they sort to the end of an event.
How do I navigate from one iPhoto event to another? I must be missing something basic...when I need to move from one event to another, I have to select another iPhoto choice (such as "Photos" or "Last Import") and then select "Events" again.
Thanks.

For Question #1, an album definitely helped. In iPhoto, I highlighted all 19 events in this particular library, selected File>New Album, and set the sort order by title. Back in iMovie, the list of photos was sorted the same.
Regarding Question #2, I figured out why iMovie was acting the way it was. I had increased the height of the photo viewer/browser pane so that the source list collapsed to a single drop-down. So the source list that normally looks like this:
...became this:
I don't think iMovie is set to allow you to go back to the list of all events without selecting some other item in the drop-down first. When the viewer pane is lowered so that the source list looks like the first screen above, you can click on Events and have it return to the list of all events.
Thanks for your help.

Working with a QuickSwipe comp

Questions about working with a QuickSwipe comp:
1) If I drag a new file into a take folder containing several takes, the new take file gets placed on top. This is fine unless I want the order to match the takes from another track. How can I change the order of takes in a take folder?
2) I had a QuickSwipe Comp all finished except that I was missing a short piece of audio. I brought the new audio into the take folder, but I didn't drop it into the exact right location. I had to move it, so I picked it up and moved it. Somewhere in this process, Logic erased all the QuickSwipe work that was previously done on the takes below this layer (all the way from the beginning to the end of the song). I don't know if it was when I first dropped the track in the take folder, or when I moved it, or what. What happened and how can I avoid this in the future?
3) In #2, the QuickSwipe comp that disappeared was on a comp track that was grouped with another comp track below it. "Editing" was checked in the group settings. When the QuickSwipe comp was erased by Logic, this only happened on one of the comp tracks. Somehow, Logic allowed me to use QuickSwipe to recreate my previous work on the screwed up comp track without affecting the other comp, even though editing in sync was still turned on. I would have expected to affect both tracks by applying QuickSwipe changes to one of them. This seems like a bug, even though it worked in my favor this time. Is it a bug or what?

Working with RAW files

I have a Nikon D200 and have been taking some pictures in their RAW format (.NEF) and have some questions. It transfers the pictures fine but then does some other weird stuff.
Sometimes, for seemingly no reason at all, when working in iPhoto, it changes the format to a jpeg and while others remain RAW. I looked in my iPhoto Library in my user folder and it looks like iPhoto automatically converts every RAW picture into a jpeg. But in the iPhoto window, sometimes you're looking at the jpeg and sometimes you're looking at the RAW. Is there some way to make iPhoto act more consistently? And can I make iPhoto stop automatically creating a jpeg version of each RAW photo?
Also, I exported some RAW pictures as TIFF's to work with in photoshop. Once there, the pictures only have a dpi resolution of 72 pixels per square inch. That's way too low for my purposes. Does anybody know if there is a setting or something where I can change this?

Oracle UCM - Working with forms

I have a question about working with fillable forms in Oracle UCM. I have a requirement to display a fillable form on a website and have the fields that the user completes in that form stored in Oracle UCM some how. I have played with the forms editor and I have made a form. I see that I can map results into content server metadata fields.
Is there a way to use this utility to create a file which is in turn checked into content server when the form is submitted. Is there a better way to do what I am trying to accomplish.
Thanks in advance for your help,

How to work with saving projects/selecting, How to work with saving projects/selecting

Hello,
I have a couple questions about working with FCP X folders, projects, etc. So basically, I have all of my Macs home sync excluding the "Movies, Pictures and Music" section with those having dedicated AFP shares on my Lion Xserve. I figured out the Aperture and iTunes part and it works very well for me using the "Home Sharing" and "Merge" library feature in Aperture and iTunes. How would I go about doing something similar with all of my video projects? When I am activelty working on projects, I want them to be in the "Movies" portion of the computers home folder, but I would like to be able to then store it on the "Video" AFP share I have on my server for archival purposes and accessing them on my other netwokred Macs. How would I do this? Do I just drag the stuff from the video folder? Will FCP X on other Macs open this succesfully? Sorry if I sound stupid, but I am very new to FCP X, switching from FCS.
Thanks!

If we want the sequence table shall we have to create it seperately or will it creates directly?

If you can't sign in, then you can't troubleshoot and/or pair the keyboard until after that........ so, for that, you will need to borrow someone's USB wired keyboard in order to get signed in and to the Keyboard Bluetooth Preferences.

Does Final Cut Express 4 work with mac mini and other questions...?

I have a few questions I need help in answering... I would appreciate opinions on the following:
I am about to make a purchase of a new mac. I already have a mac mini PPC, but it is too slow...
Here is what I am thinking.
Mac mini, 2GB mem, 160GB hard drive. Will this new mac mini work with Final Cut Express 4?
Or should I go with the more powerful iMac?
I like to make movies on my mac but I hate iMovie 08 so I constantly use iMovie HD 06. Should I go to Final Cut Express 4 or just stick with iMovie HD 06?

There is no doubt that FCE 4 will run on an Intel mini - the GMA graphics processor is compatible. There is also no doubt that an iMac would give you somewhat better overall performance, though it's important perhaps to note that as complex as FCE is, it is actually a little less demanding on hardware than iMovie has traditionally been, so the difference between a mini with 2Gb RAM and a similarly equipped iMac will not be all that great in FCE, though it will become a little more noticeable if you continue to use iMovie 6.
The main reason for the performance difference between iMovie and FCE is that in order to provide a reasonably sophisticated video editing package that will run on very basic hardware, Apple relied heavily on caching techniques, meaning that while FCE basically spools from video and relies on CPU power, iMovie constantly moves data to and from the hard drive. The mini's hard drive is a (relatively) slow device in comparison to the iMac's - thus the iMac runs iMovie rather more seamlessly. In FCE, the difference is, as said, rather less clear unless you were to go for the top-end model.
If your budget can stretch to an iMac it makes sense to go that route simply because the extra power and overall performance (and the better graphics processor) will give you greater flexibility down the road. On the other hand, if funds are tight and you need to spend as little as reasonably possible, a mini will do fine, and is sufficient;y inexpensive that in a couple of years could be sold off and replaced without severe financial implications.
In terms of the choice between FCE or iMovie, beware that if you haven't used FCE before, the transition is not easy, and the learning curve for it is pretty steep. That said, it has far greater power and flexibility in terms of what you can achieve with it than has ever been possible with iMovie.
That said, for casual and home use, iMovie (version 6 at least) has plenty of power and tools for the majority of projects. iMovie 8 is, in many ways, deeply flawed for those who want that sort of power and workflow tools, being that it is designed for quick and easy creation of movies, not creative and considered productions. It has it's uses, but if you have experience with iMovie already, v8 is really not intended for you at all.
All that said, I've used iMovie 6 on systems will a lot less power than the current Intel minis, and have found it stable and workable, so I have no doubt it would work well on any current Mac.

Working with Pages and Word-questions!

NOTE: Sorry for the similarity of this to my post a few minutes ago titled "Which do I use, Pages or Word)? I learned some things through experimentation and have created subtler and more challenging questions for you.
Help me out here (please). I am now working with Pages, sharing documents with dozens of behind the times colleagues who are using some old program called "Word." It's my job to work with these people and I'm trying to make it as easy for everyone as possible.
Do I have this right? When I create a document (or open an old Word document into pages), in order to be able to share it with people, I save it, and check the box to save a copy in Word format. Then when I send my documents, it works like a charm. Yes?
If I start by opening a Word document, and every time I save I check "save copy to Word," I end up with only one document, no version in Pages. If I start with a Pages document, or save without checking the box, I end up with two separate versions of the document (like when I create a pdf)? It appears that if I I want to keep working in the Word format, every time I save it will give me a dialog box and make me check the box (and possibly select my location). This is cumbersome since I am now in the habit of saving often (you learn that when you work with Word for the Mac for any period of time--bomb, bomb, bomb). So, an I correct in assuming that if I want to save regularly, I really have to work in Pages, and then be scrupulous about saving into Word when I'm done for the day, or just before I send? It's sort of a pain in the butt, although I can learn to do it--I just want to make sure I'm not missing something here. Also, is there an autosave function so I don't have to rely on my discipline? Or does it never ever bomb?
What happens if I open the Word version and make changes to it? Do I have to do something differently to make sure I have both versions identical? Am I better off always to open the Pages document to work on, then save and send?
Do I always then have two versions of the same document (like I would if I did this same thing with pdf)?
How do I make sure that the Word version is always up to date since that is the one I am sending to colleagues? Do I always have to save and check the box, and then select the correct document to send?
I do see that when sending a single document I can easily send it while I am in the document itself. When I do this, selecting to send it as a Word document (or a pdf for that matter), will it send the version I most recently saved, or the version that is on my screen (if I forgot to save changes)?
FInally, I'd be open to any tips from people working regularly with others who must use Word. I want it to work as simply as possible, but want to set up some good habits from the beginning.
Finally, finally, have you had problems with compatibility. I have to say that there have been very few Word document yet that I've opened that I haven't gotten a message that says that Pages doesn't support some aspect of the document and formatting is removed, or spacing is different, etc. The most common is that "paragraph borders operate differently so all borders except outside borders have been removed." I'm a bit nervous about this--will I be getting documents from others that I can't trust? Will I have to ask them to send a pdf as well so I can confirm that I got it right? Can anyone ease my mind? Or am I living in reality?
Thanks a million!

Well yes they are not the same program so there will be differences.
For example Pages only allows a border all the way around a paragraph with few options on the style of line, which is why you got the warning.
A workflow would consist of you doing your work in Pages however you like it and when you have finished and saved, making a Word copy which you despatch to your colleagues and then throw away.
Of course this is more cumbersome than sticking with MsWord which is another option. You choose. It comes down to whether or not you have to tightly conform and interact with Word users. Maybe Pages is not for you, or even NeoOfffice which is a clone of MsOffice.
Test it. If it works and you like it stick with whatever solution works for you.

I would like to buy an iPhone for my friend in Iceland. Two questions: will the phone work with complete utility in Iceland, and if so, what should I do to confirgure it while in the USA so that it can have full utility in Iceland?

I would like to buy an iPhone for my friend in Iceland. Two questions: will the phone work with complete utility in Iceland, and if so, what should I do to confirgure it while in the USA so that it can have full utility in Iceland?

Bad idea. There are no supported iPhone carriers in Iceland, thus some features may or may not work. Further, there will be no warranty or support for a US purchased iPhone in Iceland...your friend will be on their own. If you still want to go down this road, make sure you purchase an officially unlocked iPhone(GSM model) directly from Apple.

LV Version/Runtime Question (working with LV 8.2.1 -- problems with a VI that was original build with LV 7.1)

Hi there,
currently i have a strange problem and i hope some of you can help me.
Ok first i explain my situation:
My task is to expand a old testsystem that was written with LV 7.1.
During the time they began to work with LV 8.2.1 and saved the testsystem-VI with the new LV version.
Ok now my problem:
I have added some SubVIs (build with LV 8.2.1) to the testsystem which open a connection to a DUT (device under test) via fbus, usb or bluetooth (the drivers are designed for .net). But i always get a strange error message when the subVIs try to open the connection ("...Please check your connection string..").
First i checked the handover of the variables in the testsystem but found no mistakes. I also tested all SubVIs seperatly with TestVIs and they worked perfectly!!!
My question:
The main VI was original build with LV 7.1. Could it be possible that LV uses an old or several runtime engines to execute my testsystem which causes such strange problems (For me its the only logical explanation why it works with my Test-VIs but not with the testsystem)?
But maybe you know more about such problems
Greetings, wonx

Hi wonx,
it's really hard to say what might be the problem without knowing your project.
Have you already performed a mass compile in LV8.2? If not, I would suggest to do so. Please see following link for an explanation of how the mass compile option in LabVIIEW works.

You would only save about 500MB by deleting MS 2.1.3. You may find it useful to keep the application, or perhaps to make a zip and then delete the original
