what are application events and system events? what is difference between ?

The Control Framework triggers the event irrespective of the screen flow logic, that is, without processing the PAI and PBO events. These events are called system events. This type of event processing is the default setting.
·The Control Framework processes the PAI module after an event. In this case, you must call method CL_GUI_CFW=>DISPATCHto initiate the event handling of ABAP Objects. These events are called application events.
Application Event : you must first register the events for the control instance and consequently on the frontend.
like..
DATA events TYPE cntl_simple_events.
DATA wa_events TYPE cntl_simple_event.
1. Using field
appl_event , define the event as an application event:
wa_events-appl_event = 'X'.
System events are passed on irrespective of the flow logic of the relevant screen.
1. Change the value of field
wa_events-appl_event in the PBO module:
wa_events-appl_event = SPACE.

I think there might be information there on how to reset Time Machine to do a full backup. I think you basically have to reset it and start over.

Hi
I have a problem with your app store, always I want to update a new app, I want to know what Schiffer and novelty app! Most of my applications are in English, and they write what the improvement and renewal are written in English, and I do not speak the language! I try to copy the text, color (gray) is not successful, the variance can it, so we can copy the text and translate?
I thank you for your help, it can help to humanize

You are right, but how could i send it to Apple? when the phone company first replaced my iphone they had in stock alots of iphones and they just sent mine back to Apple and gave me a new one, so all i did is to give them my phone, but now how could i sent it to Apple? and i cant send it by myself, and the store wont do that, its a lost for them.. so sending it to Apple wasnt an option from the begining.
and for the record, i dont think the store where i bought it is an authorized shop.. its just a store who boughts phone's from Apple in a low price and sells it in much more money..

What are the best storage systems to archive inactive (but still used) apps and files?

What are the best storage systems to archive inactive (but still used) apps and files of all types? I already have a Time Casule which I back up on and I'm needing to create more space in my flash drive in my Mac Pro, so I need another external storage system I can use to archive all that I don't currently need. I may still wish to edit and use the files, and I am not very techy and am a broke student... so anything grossly expensive is a no-no for me (between $50 and $200 is idyllic). If you could simply post links of different good/useful hard-drives that I can use, I'd be thankful.
Thank you
p.s. I'm australian, so anything within this country would be great. Or I can deal with somewhere that has cheap shipping.

It's been moved and seconded. Any discussion? Yes:
Buy two external drives. Use one for Time Machine. Be sure this drive is at least twice the capacity of your computer's hard drive. Use the second drive as a bootable clone of your computer's hard drive. Should something happen you can immediately get the computer up and running from the clone until your restore from the Time Machine backup. This is what is called redundancy. Should either backup drive fail, there's another to take its place. Backup redundancy is very important. You can never have too many backups.

I Have the same problem, I switched off location services, maps in data, whatever else maps could be involved in nd then just last nite it chewed 100mb... I'm also on vodacom so I'm seeing a pattern here somehow. Siri was switched on however so I switched it off now nd will see what happens. but I'm gonna go into both apple and vodacom this afternoon because this must be sorted out its a serious issue we have on our hands and some uproar needs to be made against those responsible!

Thank you.

Therer are two ways you can assign an action to the "OnEnter"-event of your input field:
1. in method cl_wd_input_field=>new_input_field you have the parameter:
ON_ENTER
You just have to assign your action name to this field and it will be called on the OnEnter-event of your InputField.
e.g:
     lr_input_field = cl_wd_input_field=>new_input_field(
                                             id = 'INP_MY_INPUT_FIELD'
                                             on_enter = 'MYACTION'
2. You can use the method SET_ON_ENTER.
like:
     lr_input_field->set_on_enter( 'MYACTION' ).
Just make sure, you have created and implemented this action and its handler.

What are the pros and cons re using an intel iMac vs MacPro with LP8?

I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
Best of luck!

Query as Web Services!!! What are its uses and why do we need it?

What are its uses and why do we need it.. if other tools like Dashboard and crystal reports and Webi can connect to universe and create reports and Analytics...

Hello Rajsan Madhavarajan
Query as a Web Service (QaaWS) is a SAP Business Objects (BOBJ) client-side tool that allows users to create and publish Web Services that can be made available over the Web. Once these web services are created and published, they can be consumed like any other standard Web Service in software applications including Xcelsius and Crystal Reports. But first we have to understand what exactly is a Web Service.
Web Service
A Web Service is a software system that supports interoperable interaction over a network from one computer or machine to another but is more commonly defined as a client and a server communicating data over the Web using the HTTP Protocol. Using Web Services along with Business Objects allows a live connection of data to be used in applications such as Xcelsius and Crystal Reports through a semantic layer called a Universe.
Query as a Web Service (QaaWS)
The two main components in QaaWS are the Client Tool and the Server. The QaaWS Client Tool gives the end user an easy to use wizard that allows them to create Universe queries and publish them as Web Services. Once the QaaWS is published, any user can securely access the data that the Web Service contains as long as they have access to that server. Have a look on image below that shows the information flow to and from the server via the client.
Advantages to QaaWS:
Very easy to use and intuitive interface Familiar look and feel for people who have used Web Intelligence
Leverages existing Business Objects Universes Shares metadata with Web Intelligence, Desktop Intelligence and Crystal Reports
Maintains Business Objects Enterprise Security
Allows live data feeds to be incorporated into Xcelsius Dashboards and Crystal Reports

Upgrading from 10.4.11 to 10.7. What are the steps and do I also need to pay for 10.5 and 10.6 along the way?

Hi. I wannt to upgrade from 10.4.11 to 10.7.
What are the steps and do I also need to pay for 10.5 and 10.6 along the way?
According to the 10.7 lion page on 'store' it says that you need 10.6 to use it does this mean I'm going to have to do 3 upgrades?
Thanks

Why do yoy want Lion/10.7???
Anyway, if your Mac meets the requirements you can skip 10.5.x, and even 10.6.x if you can afford to erase all your data.
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 4GB at least)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.
Which apps work with Mac OS X 10.6?...
http://snowleopard.wikidot.com/
It looks like they might still have it...
http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory[14]
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading[14]
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

What Are Application Keywords in Snow Leopard?

I recently updated to Snow Leopard, and I've been trying out the expanded syntax coloring. However, I cannot find one example of code colored as an application keyword.
I set the color for application keywords to bright red so it would stand out. I have hundreds of AppleScripts to test, and I have opened about half of them. Not once was any code colored as an application keyword. There were classes, properties, enumerations, parameters, commands, etc., but no application keywords.
So, what are application keywords in Snow Leopard? I thought I knew, but now I have no idea.
Any ideas?
Thanks
Brett

Thanks for the info. The 10.6 changes documentation says:
*Syntax coloring for scripts now has much more detail: commands, parameters, classes, properties, and enumerated values all have their own category now, instead of sharing the “application keywords” category, and may be formatted differently depending on whether they come from an application or a scripting addition.*
Does that mean all application keywords are now in different categories? If so, why is there an application keywords option in the syntax coloring prefs?
Thanks
Brett
