The best way to start with JDeveloper

Can anybody tell me what the best way is to start using JDeveloper? Besides Oracle Manuals, are there other ones? Thanks for responding!!

It would be nice if you can specify what is your background. Which tools/languages you used before?
If you don't know Java pick up a Java book that will teach you the basics and the syntax.
A good free online book is : http://www.mindview.net/Books/TIJ/
Then use JDeveloper to do the code samples in the book.
Use this tutorial to understand the basic of the JDeveloper IDE:
http://www.oracle.com/technology/obe/obe1013jdev/10131/introide/introjdevide.htm
Then once you got the basics you should probably try out the ADF tutorial to see how you build a complete Web application that interacts with a database:
http://www.oracle.com/technology/products/adf/learnadf.html
This page also contains the ADF Developer Guide book.
In addition the JDeveloper home page has links to more demos tutorials and how-to's:

Please suggest me the best way to start learning about Oracle Purchasing.

Hi,
I have started reading about Oracle Procurement. I have an over all idea of how ERP functions. Anyhow I am like a fresher to ORACLE APPS. Can you pleasesuggest me what is the best way to start learning about Oracle Purchasing.
Is it is throuhg user guides or some thing else..... can you please specify the references also.......
Thank you so much.

If you have a sponsorship, I would recommend taking classes with Oracle University. The other resources are documentation, functional and technical depending on what your interests are.
If you can load Vision database or access vision database (I think solutionbeacon offers a free account to login and play around), that will be another resource as well.
As you learn, join as much user groups like this one, and review all questions and answers in the discussions to understand and learn more.
Hope this helps.

What is the best way to deal with different audio sample rates on the same timeline ?

what is the best way to deal with different audio sample rates on the same timeline ?

You don't have to do anything special. If possible, start your project with a clip that has the desired target frame rate and audio sample rate, and your project parameters will be set automatically. Other sample rates will be converted under the covers.
For example, if your video is shot at 48khz, you can add music files at 44.1khz with no problem.
If you are recording audio that you want to synch with video (multicam), you will get best results if everything is 48khz, but you can use 44.1 if that is all you have. Once I forgot to reset my Zoom to 48,000 and it still worked.

What is the best way to work with Word documents in The InDesign CS4???

I work in Microsoft Word 2007 and all my documents have *.doc format.
What is the best way to work with Word documents in InDesign CS4???
David Blatner says to avoid copying and pasting text from Word instead of placing it (Ctrl+D).
How about pasting RTF or Text Document???
I want to make book's layout in ID CS4 and its main feature is that there is the left page with text and the right - with graphics.
So, as I understand to place the text on each page I must create for example 70 Word documents and place each item on 70 left pages???
It loks like wasting time. I sthere another way of making such layout??? What kind????

It's best to place any text.
You can have all of your text in one file and use auto-flow to add threaded text frames and pages as required (Hold down the Shift key when you click the loaded text cursor), but it's a little non-standard to have the thread only on one side of the spread from the auto-flow perspective, so you'll have to set up properly.
This is one case where a master text frame will work to your advantage. On your master page spread, add a text frame to the left page, but not to the right (or at least not threaded to one on the right -- for some other project you might actually want two independent text threads). Hold the loaded cursor over a frame on the left side of a document page and auto-flow. ID will add new spreads as necessary, but only put the text on the left side.

How is the best way to deal with duplicate photos

I am using a new retina 27" iMac 16gb ram OS X 10.10.1
Aperture 3.6
What is the best way to deal with duplicates that get in Aperture Vaults
I have used Gemini and it finds duplicates, but I have no way of telling if the original are still there.
I don't want to go through 15000 photos to try to find the duplicate.
Thanks Charlie

You mean - one image in a vault, one in a library? Or duplicates in the same library?
Photo Sweeper can scan several libraries or folders at the same time and display the duplicates side by side to let you pick which to keep. You can define rules to mark photos for automatic deletion as well.

What's the best way to deal with floating point errors?

What's the best way to deal with the decimal number errors in Flex?
Lets say I have:
var number1:Number = 1.1;
var number2:Number = 1;
var result:Number = number1 - number2;
trace(result);
I get "0.10000000000000009".
What's the best way to deal with this so that i get the right result?
Using the trick: result = Math.round( result * Math.pow(10,13) ) / Math.pow(10,13); is not useful as such when using big numbers.
For example, If number1 = 100000000001.1, and number2 = 0.2, I get "100000000000.90001" as result. The previous rounding fixes rounding errors after 13th decimal, but here the first rounding errors come after 4 digits.
The toPrecision method in Number and NumberFormatter dont seem be of use by themselves because of the same reason.
So I'd have to check how big the number is, and then round the number based on that.
So far I've constructed a method that does that with logarithms like this:
public function floatFix(number:Number):Number{
      var precision:int = 14-Math.floor(Math.log(Math.abs(number))*Math.LOG10E);
      var precisionFactor:Number = Math.pow(10, precision);
      return Math.round(Number(number*precisionFactor))/precisionFactor;
It just seems rather odd that one would have to create and use something like that to just count 1.1-1; There's a lot of calculating in that method, and i'm guessing that having to use that in a loop could slow down a program quite a bit.
I think there really should be a pre-built method in flex for something like this, but I can't find any.
Anyone know any better/faster ways?

What is the best way to deal with memory leak issue in sql server 2008 R2.

What is the best way to deal with memory leak issue in sql server 2008 R2.
I have heard of memory leak in OS that too because of some external application or rouge drivers SQL server 2008 R2 if patched to latest SP and CU ( may be if required) does not leaks memory.
Are you in opinion that since SQL is taking lot of memory and then not releasing it is a memory leak.If so this is not a memory leak but default behavior .You need to set proper value for max server memory in sp_configure to limit buffer pool usage.However
sql can take more memory from outside buffer pool if linked server ,CLR,extended stored procs XML are heavily utilized
Any specific issue you are facing

What is the best way to work with AVCHD 720 24p footage in FCE4.1?

Hi I have a Panasonic HMC-150 and I've been shooting 720 24p footage at 21 mbps transfer rate.
I was wondering what is the best way to work with this material in FCE 4.1? I see that in the easy set up menu they only have the option of 1440X1080i at 50 or 60 fps or 1920X1080i at 50 or 60 fps.
Also in the rates drop down menu there is only 50 or 29.97.
So I was wondering which is the best choice for 720 24p footage and will it look alright in any of them? Also is it possible to customize these settings?
And finally can you work with faster transfer rates (21mbps) in FCE?

Yikes, this is going to be tricky since FCE does not support native 24p editing.
The work around for some of us is that AVCHD material that is 24p is often recorded to disc at 60i using telecine, in which case it can be editing at 29.97 frames per second, and then detelecined afterward for final export at 23.98 fps. The problem is that I think your camera actually records real 24p - not 24p packed into 60i. When you import the material from the camera what does QuickTime report the framerate as?

What is the best way to work with mixed media in 1080 timeline?

Hi there,
I have a project shot mostly in 1080 24p but a bit of 720 24p and 4x3 30p footage.
What is the best way to work with this mixed media?
Thanks!
Steven

Hi Shane,
Ok just to recap (thanks for being patient by the way)...I have put some questions in here...feel free to write in caps to respond and we'll put this baby to rest!
1) I will work in a 1080p FCP sequence, correct?
2) HD 1080p footage captured as applepro res hq I will leave as is and work with?
3) HD 720p footage which was captured as applepro res hq. Can I just drop in 1080 timeline and let FCP do its work? Or should i run through compressor, if so what setting shall I submit it too?
4) I dont have a budget for an external hardware to convert SD to HD...should I capture my SD Beta through Final Cut and just leave and let FCP do its work? Or should I run through compressor? If so what setting shall I submit it too?
5) For for my master sequence in FCP am I not using an I-Frame format apple pro res if I am using my apple pro res hq 1080 footage as my formatted sequence? I am not sure what you mean by GOP?
6) I also found some 60p footage 1080p XDCAM compressor shot with the same XDCAM camera. I put in the 1080p 24p timeline but it was pretty choppy...any ideas of this conform?
Thanks very much for all your help it has gone along way,
Steven
Saying what CODECS you are working with was my question. 1080, 720, 4:3...really says nothing. There are a dozen 1080 codecs, another dozen 720 codecs, and nearly 100 4:3 formats.
Best to capture all the footage to one uniform codec.
Second best is to work with one format and let FCP conform the rest to that...IF and only IF that format is an I-Frame format like ProRes. GOP formats as master sequence formats cause TONS of issues.
What I'd do is work 1080 ProRes, just add the 720p footage (Use Compressor to convert it if you didn't have a lot, but if you had a lot, just add it), but I'd capture all the SD 4:3 footage via a Kona 3 or Matrox MXO2 as 1080 ProRes. Hardware conversion of SD to HD is much better than anything FCP can do. AE might do good as well. But then use Compressor to convert 29.97 footage captured (you can't convert 29.97 to 23.98 when you capture) to get to 23.98.

"Built In " battery ... what is the best way to deal with it ?

Hi ... I just bought this laptop envy6-1100se with a built in battery and I actually heard alot of diffrent opinions about the best way to deal with the battery and charging and I don't know what to trust to make my batterylife the longest so hope u can help me with that .. I want to know also if there is any damage to the battery if I kept it plugged to Ac Power even after it's totally charged ... ??

You want to minimize the number of charge/discharge cycles so yes it is actually a real good idea to have it plugged in whenever you can. Just to illustrate, Samsung makes several models with integrated batteries and they actually have a setting in the BIOS where you can choose to cut off charging at 80% battery power. If it never goes above 80%, then discharging and charging below the 80% level never registers as a cycle. The battery has a smart chip that counts cycles. After a certain number, say 500, the battery will no longer work. This is to minimize the fire hazard from older Li-ion batteries. In other words, you trade runtime on a "full" charge for longevity of the battery. You might go from 5 hours to 4 on a single charge but the battery will last 4 years instead of two and a half. The battery can actually be replaced but it is a huge pain. The "Samsung" solution is not available on HP's that I have been able to determine.
So, as I said there is not much you can do except use AC power as much as possible and treat the battery like your life savings; use it sparingly.
And I recognize that when it comes to batteries on laptops, it is like a discussion of religion. There is more than one respectable opinion but this is mine.

What is the best way to start "fresh" with iPhoto '08?

I am running iPhoto '08 on a mid-2007 iMac. When I set up the machine, I moved all the photos from my PC to the Mac retaining the existing directory structure that I had on the PC. I then imported all the pictures into iPhoto with no problems.
Unfortunately, the other person who uses the Mac needs to be able to use the directory structure as it existed on the PC (that structure involves several subfolders with specific names etc.), and it appears that iPhoto is not designed to work that way. I know the photos can still be manipulated in the folders I imported, but then I run the risk of at best, being out of synch with iPhoto and at worst, corrupting iPhoto completely.
That said, what I would like to do is delete or remove the current iPhoto library (or whatever iPhoto accesses; not the whole application unless necessary) and then selectively import photos to iPhoto. That way, the other user can access the photos in the familiar folder structure and manipulate them at will without disturbing the iPhoto db and, once photos are edited etc. and ready for primetime, they can be imported to iPhoto to gain the advantages of displaying using Front Row etc.
My question is what is the best way to achieve what I am looking for? Just backup then delete the iPhoto pkg file in the HD/Library/Receipts folder? Uninstall the entire application and start over?
All assistance greatly appreciated.

Welcome to the Apple Discussions.
You don't need to re-install iPhoto, just change the library - and you may not even need to do that.
1. You can easily recreate your Directory structure in iPhoto. Simply start at the bottom of your structure and drag a folder of images to the Source (or left hand) pane of the iPhoto Window. iPhoto will create an Album of the same name. The create your enclosing folders (File -> New Folder) and drag the albums to it. This way you can quickly recreate what you have/
2. The other user of the files can access them directly via the iPhoto Window or a Media Browser such as THIS. The advantage of this system is that your directory structure is available to them ina convenient and recognisable way. They can then drag the pics from the iPhoto Window / Media Browser to the app they as the need. (A whole lot faster than fumbling around in Folder after Folder etc, plus the advantage of keyword searching.)
3. Is this necessary for working with an editor? You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. Btw this is the only way that edits made in iPhoto will be visible in iPhoto.
4. Finally, if you do wish to go as you described: Simply trash the iPhoto Library from the Pictures Folder. Start iPhoto and it will create an new empty library. If you wish to recover the files from the Library first, then Right Click on the iPhoto Library and go 'Show Package Contents'. Your files are in the Originals Folder.

What is the best way of dealing with an "implicit coercion" of an array to a sprite?

Hello everyone!
     With continued help from this forum I am getting closer to having a working program. I look forward to being able to help others like myself once I finish learning the AS3 ropes.
     I will briefly explain what I am trying to achieve and then follow it up with my question.
Background
     I have created a 12 x 9 random number grid that populates each cell with a corresponding image based on each cell's numeric value. I have also created a shuffle button that randomizes the numbers in the grid. The problem I am running into is getting my button-click event to clear the current images off the grid in order to assign new ones (i.e. deleting the display stack objects in order to place news ones in the same locations).
Question
     My question is this: what is the best way to handle an implicit coercion from an array to a sprite? I have pasted my entire code below so that you can see how the functions are supposed to work together. My trouble apparently lies with not being able to use an array value with a sprite (the sprite represents the actual arrangement of the grid on the display stack while the array starts out as a number than gets assigned an image which should be passed to the sprite).

===========================================================================
     Any help with this is greatly appreciated. Thanks!

Rothrock,
     Thank you for the reply. Let me address a few things here in the hopes of allowing you (and others) to better understand my reasoning for doing things in this manner (admittedly, there is probably a much better/easier approach to what I am trying to accomplish which is one of the things I hope to learn/discover from these posts).
     The elements inside my "imageArray" are all individual graphics that I had imported, changed their type to movie clips using .Sprite as their base class (instead of .MovieClip) and then saved as classes. The reason I did this was because the classes could then be referenced via "getDefinitionByName" by each cell value that was being passed to it. In this grid every number from 1 to 9 appears randomly 12 times each (making the 108 cells which populate the grid). I did not, at the time (nor do I now), know of a better method to implement for making sure that each image appears in the cell that has the corresponding value (i.e. every time a cell has the value of 8 then the custom graphic/class "skin8" will be assigned to it so that the viewer will be able to see a more aesthetically pleasing numerical representation, that is to say a slightly more fancy looking number with a picture behind it). I was advised to store these images in an array so that I could destroy them when I reshuffle the grid in order to make room for the new images (but I probably messed up the instructions).
     If the "drawCell" function only returns a sprite rather than the image array itself, doesn't that mean that my "eraseCells" function won't be able to delete the array's children as their values weren't first returned to the global variable which my erasing function is accessing?
     As for the function name "drawCells," you have to keep in mind that a) my program has been redesigned in stages as I add new functionality/remove old functionality (such as removing text labels and formatting which were originally in this function) and b) that my program is called "Blanko."
     I will try and attach an Illustrator exported JPG file that contains the image I am using as the class "skin7" just to give you an example of what I'm trying to use as labels (although it won't let me insert it here in this post, so I will try it in the next post).
Thank you for your help!

What is the best way to start SAPGUI in a specific transaction

Hello,
What I'm trying to do is to run a Java program that will start SAPGUI (in windows format, not HTML) and present the user with a specific transaction with some data already inserted.
I already managed to start the SAPGUI and I know how to fill in data using the SapJCo but my question is: what is the best way to navigate to a specific transaction? I can activate an RFC of BAPI_CALL_TRANSACTION but it seems like a big overhead. so, can any of you tell me what is the best way activate a specific transaction in SAPGUI using JCo?
Thanks,
Uri Lifshitz.

Uri
JCO are mostly used to executed a RFM on the Destination.
I don't think we could call a Transaction using JCO.

What's the best way to start this dashboard?

I have a data set of titles, gender, race, and disability.
I would like to create a dashboard that will be visually appealing to the end user that relies on this information.
What would be the best way to visually represent the gender, race, and disability for each title?
Thanks in advance!

Hi Zack
Start with a blank piece of paper and draw out what you think will look ok in terms of the relationships between the data sets you have and a basic structure on areas for controls and areas for visualisations. Then create this mock up using tables/charts etc. Try to select charts which fit the data you have, see [here|http://media.juiceanalytics.com/downloads/graphselectionmatrix_sfew.pdf]
Take it to your user group and discuss, and enjoy the many iterations that follow

What is the best way to work with a large amount of data?

Assume you have a big text file to work that you need to store and work with, what would be the best way to do that?
I will be adding / removing a lot of elements so I really want to stay away from array resizing overhead.
I don't want to step on any toes here, but would binary trees / linked lists in C++ be a better solution?

Assume you have a big text file to work that you need
to store and work with, what would be the best way to
do that?Parse it into a database. Then use SQL to manipulate.
