Need to do KM customization..

Thanks.

Hi,
In Datastage, there is sorting stage specially sort the data after applying the transormations and filters seperately.
My requirement is we need to apply sorting on Target Database after applying some transformations,Aggregations and filters on source database *(Before Loading into Target data should be in the sorted Order)*
In odi,there is no sorting stage separtely for those requirement sorting the data either Ascending / Descending order *(how can i approach sorting stage in ODI)*
Thanks in Advance

How to Handle the LOV AM in the page level Controller

Hi All,
I have standard page ,In that page there is LOV in which user can select any value.
But the client requirement is the value in the lov has to be displayed has to be displayed automatically the first record of the LOVwhen page is rendered.
For that i am trying to handle the Lov AM in the extended controller by using
OAApplicationModule rootAM = pageContext.getRootApplicationModule();
OAApplicationModule childAM1=(OAApplicationModule)rootAM.findApplicationModule("CsfPoLovAM");
Here CsfPoLovAM is the AM of the LOV
when i am doing this i am getting the value of childAM1 as null.
Could you please let me know is there any other way of handling the AM of lov on the extended controller
And there is controller is defined for the LOV .
Thanks
Ajay

If there is no CO than you can put a new custom controller in the LOVRN ,in the PR method of new controller get the VO and call the firs() method of this VO like
LOVVO.first() ;this will full fill your requirement .
HI Pratap,
I had created a new custom controller in the LOVRN and in the Process Request.of the controller i am getting the first record.
like follows
OAViewObjectImpl vo=(OAViewObjectImpl)am.findViewObject("CsfInstallLotNumberVO1");
oapagecontext.writeDiagnostics("IN LOV CO Process Request ","vo:"+vo,4);
if(vo!=null)
vo.executeQuery();
Row row=vo.first();
oapagecontext.writeDiagnostics("IN LOV CO Process Request ","row:"+row,4);
if(row!=null){
String lotnumber=(String)row.getAttribute("LotNumber");
oapagecontext.writeDiagnostics("IN LOV CO Process Request ","lotnumber:"+lotnumber,4);
oapagecontext.putSessionValue("LotNumberParam",lotnumber);
i am able to get this lov value in the lov window when the lov item is clicked
and i am trying to handle that value in my exteded co its getting that value
Thanks

How to handle movielclip of stage by class

i m making three movie Clip A, B, C in Main movieclip on stage .
can u tell me how to handle these movieclip by cleass file in actionscript 3.0.
i dont want to access these movieclip from libaray.

For each clip in the library that you want to control from your class you set the linkage properties and give the item a class name. The class name you give it allows you to instantiate it from code.
So, say you have a document class, and want to put clip A on stage in the constructor, and you've given it a class name of LibraryClipA:
package{
     class MyDoc{
          private var clipA:LibraryClipA;
          function MyDoc(){
               clipA = new LibraryClipA();
               clipA.x = 100;
               clipA.y = 100;
               addChild(clipA);

How I can sort music files (audiobook) in music player on iPhone by file name, not by title name?

I have audiobook of abt.500 files, all titles are the name of the book. iPhone music player does not understand sorting by file names, but by title, hterfore it plays files chaotic. So, how I can sort audiobook files in music player by file name, not by title name?

I have the same problem.
I've went through the pains of merging all chapters into one big file for each and every audiobook, so that at least the chapters don't get played in random order. Month and month of work….. In iTunes 12.01. I can now order my audiobooks by title or by author.
But once they're uploaded to my blo*dy expensive iPhone 6Plus 128 (which I bought especially to have all my music and my audiobooks on one device) my audiobooks are NOT sorted by author, but by Title.
So, let's say I have 15 books by Ken Follet, they don't appear as Ken Follet > Title of the book but they are sorted alphabetically with all the other titles of other authors.
iPods where originally designed for music and audiobooks, but each and every version of iOS makes handling your music and especially your audiobooks harder and harder….
I am very disappointed and after so many years of using apple, I am considering to move on to android devices.

How to Prevent Sorting on Hyperion Interactive Reporting ?

Dear All ,
I am having an outline in specific order , When I make the OLAP query to use my Alias table in Hyperion Interactive reporting ,
The data retrieved in a sorted way for the outline but sorting alias
So how to stop sorting ? and how to make retrieve 2 columns near each other ; one for members name and its corresponding Alias

add a stage covering rectangle to the lowest layer of your external swf and make sure the stage sizes of the loading and loaded swf are the same. convert that shape to a movieclip and assign an instance name (eg, bg_mc). in the actions panel, you can use:
bg_mc._alpha=0;
bg_mc.onRelease=function(){
bg_mc.useHandCursor=false;

Better documentation of how LR handles metadata

I would like the on-line help to accurately describe how LR handles metadata, especially writing them in files like DNG and TIFF, the usage of sidecar files (.XMP), and how all of that interacts with Adobe Photoshop CS and its Browser, and Photoshop CS2 and CS3 and Bridge.

The short answer is that the IPTC, EXIF and other built-in core metadata is written to DNG and TIFF and JPEG and travels with the file and can be viewed in any application that provides xmp functionality to view it - like a File Info... menu item. Metadata about changes made to the file and how it looks is not carried as embedded metadata when the image is exported. There is no functionality in CS2 or CS3 to view a sort of history file with images alterations.

How to Handle Unwanted Contact Requests

Unfortunately, there is currently no method to sort or filter incoming contact requests.   I think it would be very difficult for Skype to determine if a certain person is a potential scammer or spammer, unless they receive relevant reports from users who receive suspicious contact requests from them. Below are some suggested steps on how to deal with unwanted, random, unknown, or suspicious contact requests.
1. Take note of the username and display name of the user (please see image sample below)
2.       Open the Contact request then click the Block Button.
3.       The Block This Person window will also appear, you can click the Report Abuse box if you feel that that contact is indeed a highly potential scammer or spammer.  Click the Block button to confirm your action.
4.       You can also report them to [email protected]
Then Skype will be notified of the suspicious activities of the reported user/s and will most likely prompt them to check and investigate those users. Their account might be put under suspension, termination, or prevent them from creating new accounts or using Skype services.
Note: Setting your account's privacy settings to allow messages and calls from people in your contact list only will only prevent the ability of non-contacts to call you or send you instant messages. It will not stop unwanted contact requests from random users.
IF YOU FOUND OUR POST USEFUL THEN PLEASE GIVE "KUDOS". IF IT HELPED TO FIX YOUR ISSUE PLEASE MARK IT AS A "SOLUTION" TO HELP OTHERS. THANKS!

I think the problem results from the level of visibility Skype users present. For these random requests to come in, there must be some way of trawling for Skype IDs, which would allow would-be scammers and spammers to make the requests. My wife gets many of them and I get virtually none, so they obviously target women.
If Skype users could manage their level of visibility to prevent random trawling or browsing, but allow targeted searches, that should reduce the incidence of this problem enormously.
Another way would be to create an option for a "Contact Token" which could be forwarded to people you allow to make contact requests. They would need to supply the correct token (matching your individual "Contact Token") in order for the request to be submitted. ie. in Privacy Settings, add the followng option:
"Only accept and display contact requests from users supplying the following Contact Token: _____"
This may seem overly heavy-handed, but it would suit many people who don't want to be bothered by nuisance contact requests, and if they like spam and scam, they don't have to enable the option!

How can I sort lines of data (alphabetically) in the new pages 5.0?

How can I sort lines of data (alphabetically) in the new pages 5.0?
It was very simple to do in the previou version of pages.

I'm not sure why people are torturing themselves with Pages 5 given the nearly universal outcry on this forum and the incredibly negative reviews elswhere, such as the App Store.
Pages 4.3 should still be in an iWorks folder within your Applications folder. Just use that.
Please remember to tell Apple what we need from them at:

Hi Uday,
Its occurs because you're trying to access a objects with null reference. Or you forgot to create an instance or an error occurs during the instance creation. So You should put all your "Procedures and business logic" inside a Try/catch block. as follow.

The TRY block defines a guarded area whose class-based exceptions can be caught in the subsequent CATCH blocks. If no exception occurs in the TRY block and it reaches its end, the system continues the processing after ENDTRY. If a class-based exception occurs in the TRY block, the system searches for an exception handler in the same or an external TRY control structure.

How to handle null values in RTF templates

Hi - I have two groups in a report for different SQL and two formulas for each group, CF_ELE_CNT and CF_ELE_CNT1. In the template I use the below code to print or not print a section.
<?if:number(CF_ELE_CNT +CF_ELE_CNT1) >0?>
The problem is when there is no data in the second group its not creating the XML tag for CF_ELE_CNT1, though CF_ELE_CNT has 13, it still does not print that partucular section. If I remove CF_ELE_CNT1 from the condition it works fine. I was wondering how to handle this.
Any help would be appreciated!!
Thanks,
Rav

Hey Rav,
You can add a check to identify it the element/tag is present or not
<?if:(CF_ELE_CNT1)?> will give true, if the element is present otherwise falsesince you are adding the two elements, you have to add a or condition.
<?if:(CF_ELE_CNT and number(CF_ELE_CNT) >0 ) or ( CF_ELE_CNT1 and CF_ELE_CNT1 >0)?>
