Help debug the program

i have write an java program that come out with this error, how to solve it?
postageApplet.java:5: postageApplet should be declared abstract; it does not
define itemStateChanged(java.awt.event.ItemEvent) in postageApplet
public class postageApplet extends Applet implements ItemListener,ActionListener
^
what does it mean by abstract here?

You said the class implements ItemListener but you have not defined the methods for that interface. Abstract classes can have abstract methods, or methods that have a prototype but are not defined. If you made the class abstract it would compile because the methods for the interface would be considered abstract.
To fix the problem implement the methods for the interfaces you are using.

How to debug the program in background

hi
how to debug the program in background

Hello everyone,
I often debug my programs via the sm50 transaction and it works very well (especially when you put the dummy loop ^ - ^ ). However we are confronted to a major problem when more than one user tries to debug. We get a message saying that the maximum number of users in the debugging mode has been reached!! Thus we each have to wait for our turn to debug our program. It's a real pain.
We've searched for a parameter to configure the number of users for the debugging mode but in vain
Has anyone else had this kind of problem? If yes, what do I need to do to correct it?
Any suggestion would be helpful as I am new to BW.
Thank you beforehand.

Hi,
In case if you want to use in parameters statement, then we can use the suffix MATCHCODE OBJECT syntax.
Eg.
report abc.
parameters : a(10) type c matchcode object ZBELNR.
Hope this helps.

Please help find the program

Please help find the program to block unwanted number, call and SMS, that not all block number ,but the number on which you want to.

Which part of "The 5310 is just a java phone that cannot support applications like this." did you not understand?
If you want to achieve any form of blocking at all, it won't be with that phone. Your operator may be able to help by putting a block in place on their end, though, but I doubt it.

Debugging the program that will get triggered for a particular output type

Hi all,
I have one program,which will get triggered when a Sales order of type 'VOR' is created.Whenever 'VOR' order is created it will trigger the 'ZALT' output type.And this output type 'ZALT'has been configured to my program.This output type configuration has been set up by my functional consultant.
My problem is I created Sales order of type 'VOR'.But I want to debug my program,which has to be triggered because of that 'VOR' sales order type,which in turn triggers 'ZALT' output type and in turn triggers my program.
My problem is I created Sales order of type 'VOR' by keeping debugging point in my program.But it is not going to my program and simply displaying sales order has been saved.
So is the outtype has been configured properly?.Do I need to go to my functional consultant?Could anyone explain in this regard?
Rgds,
Balaji

Hi Balaji,
If possible, try to repeat the output in the output type messages screen of VA02 and change its dipatch time to '1'(Through further data). Now put the break point in the program assigned to output tye 'ZALT'(You can see this in the TNAPR table) and run the program RSNAST00 through SE38. The program will stop at the break point.
If its not possible to repeat the output and if you want to check it the first time the output type is processed, ask the functional consultant to change the dispatch time in the condition record that is being retrieved for proposing the output type to '1'. Now run RSNAST00. The program will stop at the breakpoint.
Thanks,
Vinay

Help, make the program start over

Hi!
I want to make this program to start over, an something is wrong, but I can not figure it out, this is new to me. the program is in swedish, but I will try to explaine the functions.
If you type in zero (0) the program will halt and ask for a value greater then zero. However when you type in a greater value, it will never do the actual calculation. If you from the begining type in a greater value it will do the math. Can anyone help me to correct this.
Plattform: mac and eclipse, with latest updates.
Java code:
import static javax.swing.JOptionPane.*;
public class sf?r {
     public static void main (String[] arg) {
     String indata;
     indata = showInputDialog (null, "Ange radien i sf?ren du vill r?kna ut Volymen och Arean");
     double radien = Double.parseDouble (indata);
int three = 3;
int four = 4;
double pi = 3.14;
double volym = four*pi*radien*radien*radien/three;
double area = four*pi*radien*radien;
while (radien <=0) {
     indata = showInputDialog (null, "Felaktigt v?rde, Ange ett v?rde st?rre ?n 0");
     radien = Double.parseDouble (indata);
showMessageDialog (null, "Volymen ?r " + volym + " Arean ?r " + area);
System.exit (0);
Martin

   while (radien <=0) {
     indata = showInputDialog (null, "Felaktigt v?rde, Ange ett v?rde st?rre ?n 0");
     radien = Double.parseDouble (indata);
} this test for 0 is after you do the calculations:
double volym = four*pi*radien*radien*radien/three;
double area = four*pi*radien*radien; you need to test for 0 before the calculations.
just FYI, when posting code, there are "CODE" tags (look at the top of the posting window). It'll make the code much easier to read

DEBUG THE PROGRAM

Hi Friends,
Could u guide me how to set breakpoint and debug the module pool, function pool, Interface pool and class pool program ?
Thx in Adv.
bapibobby

Hi Bobby,
Create a TCODE fro module pool program. Place Breakpoint anywhere in the code n try to run the tcode.It takes u into the debug mode.
All the others function pool n so on are debugged just as u run report .
Keep a break point n try to debug it.
Or else use /h in tcode to debug it from starting.

It is a Java applet that allows the user to pick 3 dinner menu items
from a choice of 3 different groups, choosing only one item from each
group. The total will change as each selection is made.
The user shouldn't be able to choose more than one item from the same

HELP TO DEBUG THE PROGRAM OF AGILENT6600X

Hello,
          First let me simply introduce this program.
          The horizental toggle switch is used to set the default value to the power supply.
          The vertical slide switch is used to read the value from the power supply(after board boot up).
          The phenomenon is when i run the vi, always pop up the indicate message"the 9v PS ID can not be recognized". The problem is why always the problem happens on the 9v PS.
          I have to say this program is not so good, if anyone can give me some guidence, I'll be very appreciate. Thanks.

PS.vi ‏44 KB

Good morning,
Without the Agilent drivers (vi's), I could not see much about the code.   Do you only get this message with the 9V PS?
Have you tried communicating with the instrument using MAX (Measurement & Automation Explorer)? That should be the first step to make sure that communication can be achieved. You could try a basic query like " *IDN? " and see what it returns. It's under "Communicate With Instrument", when you look at the "Devices" list.
Also try opening the actual Agilent VI's and monitor what is being sent over the GPIB. Compare it with the others that work. You can copy the faulty command to MAX and communicate with the instrument using the command.
Hope this helps,
RayR

Help in the programming of the Hc-sr04 ultrasonic sensor

Hi im new in labview, i have to connect the HC-SR04 ultrasonic sensor to the SensorDAQ, and i have to measure the distance betwen the sensor and an objetc, i have done a little program but the distance is very erratic, and i have seen an example but i dont underestand all the code in the example, so i dont know how to change it to do what i need, later today i will put the to vi's, the one i did and the one i have found, my code is very short adn the code i found i terrible long.
If my program is bad, can you tellme where adn why? or is not the code the sensor requieres please tell me.
If the example i add the code i really need can you explain me all the parts, and how to change it in order to function with the sensordaq.
Can you tell me how to wire the sensor to the sensor daq? i will add my connection diagram and photos so you can help me.
I have to make a tank sensor with the data of this sensor, and control a stepper motor with it, if the level is less than 20% use the stepper to open a valve, is its gratter than 80% close the stepper.
Other thing i need is when the level of the tank is gratter than 80% another mottor, non steper have to be turned on and must be running for a set time. when this set time is over a signal of "empty the tank" must be displayed.
I think is a lot of help what i need, i have wired the stepper mottor(bipolar 4 wires motor) and i make it run, i dont know how to make it run in either direction so I have to fix this.
I'm going to add photos and my vis later today, please helpme, the most important thing is to make the sensor to work.
THANKS FOR THE HELP.
Solved!
Go to Solution.

Hi nmerzul.
There are two ways to perform DAQ tasks. One is with the DAQ assistant (the one that you are using) and the low level steps (the one of the example). Basically they both work the same. The difference is that you can configure all the settings in one step with the DAQ Assistant and with the other method you can do it step by step. I modified the example with a lot of notes so you can understand the functionality of each step.
Now, to help you with the wiring of the sensor and the DAQ, could you tell me what DAQ you are using?
Thanks

Debuging the ABAP Programs

Generally how does the ABAPer do debug the programs in real time environment, and how to check the the performance of the programs.

Hi,
there are few methods for the same..
one using a break point(stop button in editor),
using tcode /h or going to utilities - abap debugger.
performance you can check using tcode se30.

Dbx to debug JNI programs stops on SIGUSR2

Hello,
I am debugging a C program that uses the Java Virtual Machine throught the JNI interface.
When using dbx to debug the program, dbx keeps on stopping on SIGUSR2 and SIGSTOP signals that are delivered to the process. I would like to ignore those an concentrate on the code I am debugging. With gdb, I used "handle SIGUSR2 nostop" command to ignore signal handlers.
Could you please help me find a similar function in Dbx.
Thank you in advance
