cand any one help me to implement these actions.
I want to be able to select item from the the list to the textarea by using the addit button.
import java.awt.*;
import java.applet.Applet;

     private Button purches, remove;

          myitems = new ItemList();
          foodList = new List();
          foodList.add("Rice");
          foodList.add("Corn");
          foodList.add("Beans");

          add(purches);
          purches.addActionListener(this);

          add(remove);

myList[count++]=items;
public void removeItem(String items){
while(myList[count]!=null){
if(myList[count].equals(items)){
String discard = myList[--count];

First of all the list does not produce any action event for a
single click. It produces an action event for the double click.
So you must use a choice list.
for the list, the function used is actionPerformed(ActionEvent
e)
for the choice list , the function used is
itemStateChanged(ItemEvent e)
you must use a "\n" in the string to bring the item to the next
line in the textarea.
I am giving the full program below.
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
public class Shopping extends Applet implements ActionListener, ItemListener
//my code here.
String items=" ";
//my code ends here.
private TextArea buy;
private Choice foodList;
private Button purches, remove;
ItemList myitems;
public void init(){
myitems = new ItemList();
foodList = new Choice();
foodList.add("Rice");
foodList.add("Corn");

purches = new Button("Add IT");
add(purches);
purches.addActionListener(this);
//my code

remove = new Button("I don't want");
add(remove);
remove.addActionListener(this);
buy = new TextArea(10, 10);
add(buy);

//my code here.
     String s = ((Choice)e.getItemSelectable()).getSelectedItem();
     System.out.println(s);

How to use a method in sequence diagram from a class diagram

Hello, can someone tell me how to use the method from class diagram in sequence diagram? so far i only can add a classifier to the object lifeline but i still cannot add the method from the class...
thx

Now that Web Services is around, I'd look at possibly implement a Web Service call in your applet, which can then be given back any object(s) on return. Set up your server side to handle Web Service calls. In this way, you can break the applet out into an application should you want to (with very little work) and it will still function the same

How to use protected method of a class in application

Hi,
will u please tell me how to use protected method of class in application. (class:cl_gui_textcontrol, method:limit_text)
Thanks in advance,
Praba.

Hi Prabha,
You can set the maximum number of characters in a textedit control in the CREATE OBJECT statement itself.
Just see the first parameter in the method . I mean MAX_NUMBER_CHARS. Just set that value to the required number.
Eg:
data: edit type ref to CL_GUI_TEXTEDIT.
create object edit
exporting
    MAX_NUMBER_CHARS       = 10
   STYLE                  = 0
   WORDWRAP_MODE          = WORDWRAP_AT_WINDOWBORDER
   WORDWRAP_POSITION      = -1
   WORDWRAP_TO_LINEBREAK_MODE = FALSE
   FILEDROP_MODE          = DROPFILE_EVENT_OFF
    parent                 = OBJ_CUSTOM_CONTAINER
   LIFETIME               =
   NAME                   =
EXCEPTIONS
    ERROR_CNTL_CREATE      = 1
    ERROR_CNTL_INIT        = 2
    ERROR_CNTL_LINK        = 3
    ERROR_DP_CREATE        = 4
    GUI_TYPE_NOT_SUPPORTED = 5
    others                 = 6
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
In this case, the max: number of characters will be set to 10.
I hope your query is solved.
Regards,
SP.

How to use protected method in jsp code

Could anyone tell me how to use protected method in jsp code ...
I declare a Calendar class , and I want to use the isTimeSet method ,
But if I write the code as follows ..
========================================================
<%
Calendar create_date = Calendar.getInstance();
if (create_date.isTimeSet) System.out.println("true");
%>
============================================================
when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

The only way to access a protected variable is to subclass.
MyCalendar extends Calendar
but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
cal.isSet( Calendar.HOUR );

How to use Aggregations Method generated by WIZARD

Hi All,
          I used ABAP wizard to develop I report.
This wizard generated one class and method as below
zcl_bt_alv_template=>factory(

                            im_lheader = gv_title

                 importing ex_alvo    = r_alv_template
                 changing   ch_datatab = it_efficiency ).
Inside this Factory Method there is one method for aggregations.
ex_alvo->r_aggregations = ex_alvo->r_table->get_aggregations( ).
How to use this Method for getting aggregations for some fields.
Thanks,
Prasad.

Hi Patel,
               I am getting DUMP for this.
Its saying Access via 'NULL' object reference not possible.
Patel when I am double clicking the
aggregation = if_salv_c_aggregation=>total
This if_salv_c_aggregation is not having any methods.
So may be the dump is coming.
The dump is
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: "R_AGGREGATIONS").
Thanks,
Prasad.

Can any one suggest me how to use drawPixels method for 40 series devices

Hello!
I am using drawPixels method of DirectGraphics class the code I have written is :-
Image offscreen=DirectUtils.createImage(width,height,0x00000000);// width and heights are integer value
public final int MODEL=DirectGraphics.TYPE_INT_8888_ARGB ;
Graphics offgra = offscreen.getGraphics();
DirectGraphics directgraphics = DirectUtils.getDirectGraphics(offgra);
directgraphics.drawPixels(imgData,false,0,width,0,0,width,height,0,MODEL); // imgData is a int array(int imgData[]) which contains required pixels of image.
The above code is working fine with NOKIA 60 series device but when i use it with NOKIA 40 series device it gives java.lang.IllegalArgumentException.
same time if i use :-
directgraphics.drawPixels(imgData,false,0,width,0,0,width,height,0,DirectGraphics .TYPE_USHORT_4444_ARGB ) ;
// imgData is a short array(short imgData[]) which contains required pixels of image. i have used different formet here.
it works fine with 40 series device,
can any one suggest me how to use drawPixels method for 40 series devices with format
DirectGraphics .TYPE_INT_8888_ARGB .

If Remote wipe is activated it can't be undone. And Once the Wipe is done, the device can nö longer be tracked.
Sorry.

How to use the method for field-exit to trigger the workflow?

Dear all,
     I want the workflow to trigger , when ever the check box for DELIVERY COMPLETED is checked in ME22N .
     I have developed a method in SE18 for the corresponding field and defined function module SWE_EVENT_CREATE with BOR bus2012 and event CHANGED.
    Now how to use this method to make my workflow to trigger?Shall I create an event in delegated bus2012 and can I call this method?
Thanks and regards,
S.Suresh

Hi
You want to place your method which is defined for particular filed.right?
For that you can go for BADI. First you check whether any badi is getting called form that tcode ME22N. Then to place your method, implement that BADI. So whenever that BADI is getting called, it will call your event. Through Event workflow will be getting triggered.

How to use secondary method in workflow?

Hi friends,
can anyone plz let me know how to use secondary methods in workflow? it would be helpful if u explain with an example..
thanks and regards,
Arun.S

Hi Arun Kumar,
The Sec Method can be used in the user decision step. The secondary methods are executed along with the user decision step. You have 3 options. Either execute a secondary method before executing the user decision step or after execution of user decision step or while executing the user decision.
For this define the methods either in Methods before execution of workitem execution to execute it before user decision step or Methods after execution of workitem so as to execute it after the execution of user decision.
In order to execute a method along with user decision step execution use secondary methods (amodal call.)
Let me know if you have any queries.
Regards,
Raj

How to use this method in JSTL?help me please!

I know I can use "<C:set >" like as
<c:set var="clabel3" value="${portalCustomizeBean.portalPage}"/> ,
but now I want to use one method of portalCustomizeBean object not a attribute of it !!!!!
who would tell me how to use?
this is wrong in my code:
<c:set var="clabel" value="${portalCustomizeBean.currentPageLabel}"/>
<c:set var="clabel3" value="${portalCustomizeBean.toEntitiesExceptSpaceEscape(clabel)}"/>
but how to use "toEntitiesExceptSpaceEscape" method in JSTL?????

Why can't you just assign the method's return value to a variable and then print that? A bit of scriptlet code will do the trick. (As much as we all hate to use scriptlet code.)
I believe you'll be able to do what you want in the 1.1 standard JSTL, but for now this will suffice. - MOD
