Here is a basic UI example that shows how you can listen for user events (pushing the button) and control the flow of your program using a task engine.
It does not match your requirements however since this is a poroject you should actually do the work. This is a framework for how you can build your application.
If you have specific questions feel free to ask them but don't expect anyone here to do the project for you.

Hi,
Here is the piece of code for your understanding...
FORM f4200_pf_status_set USING i_extab TYPE slis_t_extab.
REFRESH i_extab.
PERFORM f4210_exclude_fcodes CHANGING i_extab.( This form is mentioned below ).
SET PF-STATUS 'STANDARD' OF PROGRAM '(Program name)' EXCLUDING i_extab.( This line of code will excude the function u don't want)
ENDFORM.
FORM f4210_exclude_fcodes USING i_extab TYPE slis_t_extab.
DATA: ws_fcode TYPE slis_extab.
CLEAR ws_fcode.
ws_fcode = '&EB9'.
APPEND ws_fcode TO i_extab.
ws_fcode = '&ABC'.
APPEND ws_fcode TO i_extab.
ws_fcode = '&NFO'.
APPEND ws_fcode TO i_extab.
ws_fcode = '&LFO'.
APPEND ws_fcode TO i_extab.
ENDFORM.                    " f4210_exclude_fcodes
I hope this clarifies. Revert for any queries.

I think the user is actually asking how to stop the outer loop if the Stop button is pressed or the iteration count reaches 10.
To poster: You need an OR condition on the outer loop's conditional terminal. One OR input comes from the Stop button. The other comes from the case structure. In the False case you wire out a False Boolean constant. In the True part you wire out a True. You could also wire the OR input to the Boolean control directly since this amounts to the same thing.
Code comments:
Do not create greedy loops. Use a small delay so you don't starve the CPU.
I think you want the inner loop's condition terminal to be "Continue if True".
You can use the Increment function rather than using an Add function and a constant of 1.
You don't actually need the inner loop at all. You can use a Feedback Node.
Adding to these comments it is important to note that if you read the value of a button to control stopping a loop you should always ensure that you read it AFTER you execute all of your code in the loop. If you don't you can easily end up with an "off-by-one" execution since the button will get read very early in the loop iteration and it will use that value when deciding if the loop should exit or not. It won't use the value of the button at that instance in time (end of teh loop iteration).

How to Disable the Add & Review Button

How to Disable the Add & Review Button
*Updated with the correct ISF code (the previous code, in case you saved it, was to actually escape apostrophes.  That will be posted seperately.
Note that this solution might not work in your environment - you might have to modify it based on your installation.
Enjoy!
Common_disableAddAndReviewButton()
   if ( Moment == 'ordering' )
        var theForm = document.forms[0];
        var buttonCt = 0;
        for( i = 0; i < theForm.elements.length; i++ )
             if( theForm.elements[i].type == "submit" )
                if ( buttonCt == 0 || buttonCt == 2 )
                    theForm.elements[i].disabled = true;
                     theForm.elements[i].style.visibility="hidden";
                 buttonCt++;

This is GREAT - I added a new Java Script and set it to "when form is loaded" and when I did some test reqs - no Add & Review button !!!!

How to forward ports using Airport Extreme?

So,
I wanna forward some ports but every guide I find on the internet describes how to use the Airport Admin Utilty to do this. The problem is though that I can't configure my AE using AIrport Admin Utility; I need to use my Airport Utility instead. The only problem is that I don't know how to forward ports using Airport Utility.
Anyone?

In AirPort Utility, Port Forwarding is called Port Mapping which is under the Advanced->Port Mapping tab.

Depending on why it's been disabled, you might be able to re-enable it via this page : http://appleid.apple.com, then 'reset your password'
Or you might need to contact Apple : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
If it then works on your computer's iTunes but not your iPad then try logging out of your account on the phone by tapping on the id in Settings > Store and then log back in and see if that 'refreshes' the account on it

This report gives you the SPFLI Data and places a check box in front of each record. When u click on select all button it will select all the records. And if you click on deselect all it will deselect all the records. When you are trying this maintain the pf-status 'YMENU1' and give the function codes as in the code.

How to disable illuminated Multimedia Console Buttons sensitivity

Does anyone know how to disable or reduce the sensitivity of the illuminated +Multimedia Console Buttons+ to the left of the main keyboard?
Cheers, Alun

Firs of all it would be really interesting to know what notebook you have.
On many Toshiba notebooks you can find the Toshiba Assist.
As far as I know there you can find the Toshiba Button Support and could disable this.
Furthermore you this can be done also in msconfig (to start this you have to type msconfig in RUN)
But note; this is very sensitive operation and this could affect the OS functionality if you disable wrong process. So be careful.
However, choose the Startup tab and scroll down till you find Toshiba Button Support and uncheck it.
If you will not find this in Startup then I would recommend using other procedure.
The VAP (value added package) controls this buttons.
So if you don't want to use the buttons you have to remove button support utility. I don't know if you can remove it as single utility but what you can do is to remove VAP from the system. After restart install VAP again (download on Toshiba support page) and choose custom installation. In front of button support utility remove the check mark and continue installation.
Good luck
