having problem buying online.need your help since it's my first time here.apple is asking for my billing address but when i enter my address here in qatar,it's saying i should enter a valid zip code within the u.s.does it mean i can't buy online even if it wil be shipped within u.s. only?
To buy in for delivery in Qatar, you should be starting from the Apple Qatar site:
http://www.apple.com/qa/
Do you have an Apple-ID? if you do, then you should not have to enter your Address again, and may be able to sidestep the US Zip Code issue. -

Image00000.jpg 75 KBWhat you want to do is relatively complicated and it seems that your knowledge of LabVIEW is relatively basic. I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

I need Your Help for CAF/EU/GP/API Guided Procedures
Hi everyone, I need your help about Guided procedures CAF API, I am developing an WEB DYNPRO Callable Object for Guided Procedures, but I need to get the task name of the running proceess on Guided Procedure once time a user initiated it, if is possible? Do you have an examples?
Thenk you very muchHi,
Yes you can retrieve the task name of the running process. Here is what you need to do.
1. Get the process instance - IGPRuntimeManager - > getInstance()
2. Get the IGPActivityInstance(s) from the process instance - processInstance.getChildrenInformation().
3. Optionaly check if these child activities are Blocks or Actions. If Block drill further to get the Actions using getChildrenInformation().
4. Retreive the IGPActionInstance(s) from the Block Activities.
5. Get the IGPActivity object for these Actions using IGPActionInstance.getTemplate() method.
6. This object will have a method getTitle() which will retrive you the activity name.
Hope this helps.
Thanks

Need your help on performance issue please
Hello everyone!
I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
I attach the key classes to this message. Any help or ideas is much appreciated!
Thanks a lot a best regards
Ulrich

All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.
This is the mentioned CollectionThread

*Hi Franck,
thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
I'm pretty clueless about that, any more help on this anyone?
Thanks a lot and best regards
Ulrich

Need your help in Remodeling concept
Hi Gurus need your help in time estimations
I have a cube with data and now I need to add 10 new info objects to the cube which are including Date fields (BUDAT, BLDAT) these 10 fields will be populated to the cube from a Z table in ECC as we donu2019t have these fields in the cube we have to go for remodeling of the cube
My client requires how much time it will take to complete this
Now I want to know how much time it would take to do this (if any customer exits and user exits are required) and addition if new fields will have any effect on the current queries
Please advice in this
Thank youThe time taken will depends on a lots of factor like server speed, available memory, background jobs etc. Apart from this, the time will also depends on how much the cube is filled i.e. the no. of records in the cube. Its very abstract to tell you the exact time taken for this. But, please make sure that you have the backup of the cube which you are going to re-model. T0 say, I think 3-4 hours should be ok for the remodelling.
Thanks.

Letter/report generation...morgalr, i need your help!!
may i know the details or some sample source code of how to generate the html and import it to MS Word...i need your help urgently...may i have your email to contact u?.....please help, it is urgent!!!
You need not use an applet to write an HTML file, any application file will do fine, actually applications may be prefered due to system security and file creation. Basically the html files are just text files using HTML. Look at any book on HTML and you will be able to get the style and form down along with the syntax.
As for calling MS word, do a search on the web for a product called JPrint. It is done by a company called Neva and they also have a product called "coroutine". It is coroutine that you want. Coroutine is a native level interface for Java to Comm. The docs that come with coroutine should be saficient to get you going on the project. -
Hi, Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database" ?
When I use Connect Object Explorer, the "Connect to Server" dialog box which pops up has only 4 selections in the Server Type Drop Down List. They are Database Engine, Analysis Services, Reporting Services & Integration Services. I have read
somewhere that there should be a compact database option. but I do not see it.
What I would like to do is use free form SQL Queries against the tables in "SQL Server Compact 4.0 Local Database" .
Once I have validated these queries, then I will use them in my Visual Studio 2012 C#, ASP.NET application. I created the Local Database using Visual Studio 2012 for use by my application.
Thank you for your help..
diana4Hello,
With SSMS 2005 we have had the Option to work with SQL CE database files, but not with higher Version of SSMS.
You can use the free SQL CE Toolbax instead; see
