How to access the data in a TableView with build-in Dropdownlists

Hi,
I build up a TableView with DropdownListBoxes in the cells. All works so far but if I try to access the data in the cells I get the following error message :
     at java.lang.Thread.run(Thread.java:479)
Caused by: java.lang.reflect.InvocationTargetException: java.lang.NullPointerException
     at com.sapportals.htmlb.table.DefaultTableViewModel.getIndexForColumnInModel(DefaultTableViewModel.java:354)
     at com.sapportals.htmlb.table.DefaultTableViewModel.getValueAt(DefaultTableViewModel.java:195)
     at com.sapportals.htmlb.table.TableView.getValueAt(TableView.java:774)
     at LogonPad$MyDynPage.onClickBack(LogonPad.java:467)
Some hints ?
Regards,
Gerald

Hello Anjum,
It looks that the view is based on the master data table itself and view doesn't contain data and is a logical representation of the underlying database tables.
Moreover the view RSDVCHA is used for viewing the characteristics, basic chars and local properties.
Are you storing similar values in YMETADATA?

CDR Datastreams -how to access the data?

With apologies as I posted this to the Enterprise forum, but I wasn't 100% sure where this goes.
I'm looking to create a Java class using IDL, that is then converted to CDR, and then access its CDR representation as a series of bytes. However, I'm not looking to implement an ORB, just the CDR functionality in the data streams. E.g. I see there is org.omg.CORBA.portable.OutputStream (no way to access the data that I can see though, so it seems the CDR goodness is hidden) and com.sun.corba.se.impl.encoding.CDROutputStream (but this requires a non-null ORB to intialize it even though there is a "toByteArray" method).
Does anyone know any way to do this?

I will try that.
i created a server and a client vi for chatting .The problem is before starting the client vi it is very much required to start the server vi (otherwise it throughs an error).help me doing it independently.(if a client wants to chat with a server he should be able to do it and viceversa.)thanks

TCP/IP is not designed nor able to be an RPC protocol in itself where you could launch the server from the remote side. The server has to be basically started always by some means like autostarting or manual starting by the user. A good TCP/IP server is supposed to just run all the time and wait for clients to connect to it.
However you could enable the VI server in your LabVIEW program. This is also TCP/IP based so you will have to start your LabVIEW program somehow too before you can connect to it, but once it is started you can control that LabVIEW instance over the network through VI server functions. Best part is you can test it locally too by not applying any TCP/IP address when opening an application reference. And once you think it works you distribute the client to the other computer and test it remotely.

How to access the data stored in Java tables in E-Commerce 7.0

For the CRM E-Commerce 7.0 Web shop all the data related order templates, Shop Id and catalog variants are not getting stored in CRM tables. Can anyone please let us know where all the details are getting stored.
By searching here, in SDN Forum we found that these details are getting stored in some java tables. If this is true kindly let us know the following points.
1). How can we access these tables.
2).Where these java tables are stored .
3).Do we have authorizations to check and modify these tables.
4).If we donu2019t have authorizations to check and modify these tables, how can we get the access to them.
4).How can we write Database Queries to retrieve the data from these tables.

I am afraid, all these three entities are in CRM tables.
Web Shops - Function module CRM_ISA_SHOP_GETLIST, Table crmm_isa_shop_h
Catalog Variants - Function module - COM_PRDCAT_GET_VARIANTS (they are also stored in CRM tables) for a given catalog.
Now for the Order Templates - They are technically order objects with system status set to "Order Template" I1034. You should be able to see them in CRM tables alongwith other orders... crmd_orderadm_h and etc...

How to access the whole iTunes iCloud Library with an Android phone?

Hello all,
I am a newbie here, so please forgive me if I'm not following protocol here. I searched for the word "Android" in all of the support docs. and got 0 hits! Is there a corporate policy at work here?
I know that Google and Apple (and by extension Android and iOS) are competing hard for all of us techie music lovers out there who use both ecosytems. Well, Google Play wants to have my entire music library, Apple's ever at the ready with iTunes/iCloud/Match, and now I've even gotten solicitations from Amazon which has a "Cloud MP3 Player" with purchases ready to download that I made from Amazon in 2010, before I ever dreamed of getting MP3 files instead of a physical CD. I mean the liner notes had the lyrics to the songs right? Well, I enjoy looking at lyrics. Anyways, . . .
What are the best recommendations for how to access my iCloud music library with my Android phone?
Yes, one solution is to use both Google's and Apple's services and just duplicate everything everywhere. But, I'd just like to settle on iTunes/iCloud solution, but I have a brand new Android phone that I want to use. The iPhone 5 screen doesn't come close to my Motorola Droid RAZR Max HD! :-) Sorry, all you iPhone folks. You have all the app's., so I have to latch on to somethine for a reason why I stayed with Android!
Thanks,

Apple is pretty much the only one who does not support other platforms and it will be their downfall in the future. I have bought a few hundred tracks (and one movie) from iTunes before the competition started to catch up. Their Cloud service just came into Finland but I've already moved on to others. I've also bought music from Spotify, Nokia Music and Xbox Music. I've been a subscriber of Nokia Music, Xbox Music and now Google Music. I'm also a Netflix subscriber and I have a local IPTV service that also provides movie rentals from various providers - and guess what, they also work on all platforms.
The reality is that today was the first time in a long long time that I've actually even bothered to open iTunes. Lack of platform support will destroy iTunes in the long run. Apple is starting to look like Microsoft once did. Today you can even get Office for almost every platform - even mobile devices.
Limited access and/or features is also one of the biggest reasons that turn people away from legit services. DRM protected music was the reason I had over 20,000 MP3s before it was removed from iTunes. When that happened I deleted all the old files and became a honest, paying customer.

How to compare the data in a view with data present in a master data?

Hi All,
We have loaded some data into a Master Data Object (YMETADATA) in Development system.
Now, the same data can be present in a view RSDVCHA.
Our aim is to write a ABAP program, which would read a record from RSDVCHA and look into Master Data records and show whether it is present in the master data or not?
Has anyone written such type of code earlier, If so, please do help me out in writing this code?
Thanks in advance,
Anjum.

How to access the attributes from a method

Mahathi

Hi mahathi
You should define the parameters in the header, not in the body of the method:
You can define it as importing, exporting, changing or returning, as you need. For example, in SE80
Parameter             Cl.declar.          RefTo        Opt        Type ref
node1                    importing            X                          if_wd_context_node
itab                       exporting                                        mara
method_component().
" code here...
endmethod.
and when you have to call the method,
wd_comp_controller->method_component(
                EXPORTING     node1 = nodelocal   " not importing!!!
                IMPORTING      itab   = itablocal      " not exporting!!!
i think that it's this what you want, don't i?

How to access the element s in a hashMap with order

Does anybody know how to access the elements in a hashMap with order.
I know set is a collection that doesn't gaurantee the order so the iterator of keySet will not gaurantee the order.
Is there any way to solve this?
Thanks

If you mean the order in which the key/value pairs where added to the
map, have a look at the LinkedHashMap class. If you mean 'natural'
order, you shouldn't be using a HashMap at all then; have a look at the
TreeMap class instead.
kind regards,
Jos

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/

How do I access the data saved on my time capsule? for example, if i try to view my photos it tells me that i have 2.4gb of photos and gives me the option to "view with iPhoto"....but when i click on "view with iPhoto" nothing happens... thanks!

how do i access the data stored on my time capsule? for example, if i try to view a photo, i get the option to "view with iphoto" but when i click on "view with iphoto" nothing happens. i'm having similar trouble openning up movies, music, etc. it appears as though the files exist / saved on the time capsule (because i can see how much storage they consume), but i can't open them. thanks!

Unfortunately, Apple removed the feature to "browse backups" in Time Machine backups of iPhoto a few years ago.
You have to restore the entire iPhoto library to a separate location to be able to "see" it, and then choose the specific images that you want use.
For complete details, see #15 in Pondini's excellent support document Time Machine -- FAQ. Check the information in the pink box there.
