As i mentioned in previous thread, I have my customized front-end ready(with your help :-) ), it can be seen in attachment.
In the attached image there is one button named "wake up". So on that button press event I want to call the system function
ether wake -->> sysCall("etherwake -i eth0 <MAC address>"); <<--
As of now it only seen working in front end , like it changes its color, text on the button to "Turn off" and the status message too, but nothing is written to execute the actual command like "etherwake -----" or "net rpc shutdown --------"
So I want your guidance on this.
Did you try and read here about SYS.system()?

Hello Sir,
I have read the 5.2. System (SYS) but I got it partially,
from all of the object functions listed I think the below more relevant -
-->> string system( string cmd, bool noPipe = false ); <<--
particularly, is this, the command written below, the correct way to use it?
-------------------------------------------------------------------
string system(string etherwake -i eth0 <MAC address>)
-------------------------------------------------------------------
Also I need to call a script, so it will be beneficial as it supports script calls too, as mentioned in the brief explanation on the link.
Furthermore, while trying it, I should use it in Java-like based calculator, right?
Are there any example scripts, for 5.2. System (SYS) / SYS.system()? , used in AGLKS project? as I am using that project for my understanding of openSCADA
Thank you for your quick response. :-)

You are wrong but main argument to "system()" is "string" and you try send some wrong!
And "system()" belong to the object SYS!
The correct line will:
SYS.system("/usr/sbin/etherwake -i eth0");
Continue reading the language JavaLikeCalc for understanding!

hello sir,
Is there any way to change the things(ex. text, color, etc) in user interface front-end on "button value" instead of "button press event i.e --> ws_BtPress:".
I have added one line in the front end code but it is not taking effect.... neither it is taking any effect.
Kindly have a look at the image added.
or
if making things change in user interface front-end on "button value" is not possible.....
can we use the same button press event in "Java-like based calculator", which we used while creating widget..... if yes then how do I do it ?
Thankyou,
Wish you happy new year in advance..... :) and merry Christmas too ...

For buttons events processing is single way exclude check-button where you can get the "value" attribute.

Sure, you are wrong and no real process any events but place your code into events processing loop.
For examples see to test form's elements where some button's events process.
But bellow you have true processing for event from button "CN1_Bt1" but why you comment next line and don not place all three lines to single condition like:
if(ev_cur == "wsBtPress:/CN1_Bt1")
{
//line1
//line2
//line3
}
At all you can observe for what events pass by place print test messages code before your problem's line like that:
SYS.messInfo("TEST Wdg","Event: "+ev_cur);
And see next to console or messages archive: http://wiki.oscada.org/HomePageEn/Doc/ProgrammManual/part4/files?get=subsys_arch_mess_en.png
