How to program chapter returns

How can I program chapters to return to the menu and also have a play all?

David, stories and/or scripting depending on how you feel, a recent thread discussing the approaches below with alot of detail

How to call a dialog program with return value in another dialog program

Dear All,
How can I call a dialog program with return value from another dialog program?
Regards,
Alok.

Hi Alok,
You can you SET/GET parameters to do this.
This is some information about this.
To fill the input fields of a called transaction with data from the calling program, you can use the SPA/GPA technique. SPA/GPA parameters are values that the system stores in the global, user-specific SAP memory. SAP memory allows you to pass values between programs. A user can access the values stored in the SAP memory during one terminal session for all parallel sessions. Each SPA/GPA parameter is identified by a 20-character code. You can maintain them in the Repository Browser in the ABAP Workbench. The values in SPA/GPA parameters are user-specific.
ABAP programs can access the parameters using the SET PARAMETER and GET PARAMETERstatements.
To fill one, use:
SET PARAMETER ID pid FIELD f.
This statement saves the contents of field f under the ID pid in the SAP memory. The ID pid can be up to 20 characters long. If there was already a value stored under pid, this statement overwrites it. If you double-click pid in the ABAP Editor, parameters that do not exist can be created as a Repository object.
To read an SPA/GPA parameter, use:
GET PARAMETER ID pid FIELD f.
This statement places the value stored under the pid ID into the variable f. If the system does not find any value for pid in the SAP memory, sy-subrc is set to 4. Otherwise, it sets the value to 0.

How to fetch the return parameter while running the concurrent program

Hi,
I have created one Pl/SQLl function and register into a apps concurrent programs. how to add the return type parameter in to CP and to get the out put..
Please help me.. i am new to oracle apps technical.
Thanks in advance..
Winsky

Hi,
i don't understand the return part? You need to fetch it to where?
Simple pl/sql code for concurrent program writing to standard FND log and output file:
CREATE OR REPLACE PROCEDURE TEST(errbuf OUT varchar2, retcode OUT varchar2, param1 IN number ) AS
BEGIN
fnd_file.put_line(FND_FILE.LOG,'LOG'); --text for log
fnd_file.put_line(FND_FILE.OUTPUT,'OUTPUT'); -- text for output
errbuf := '';
retcode := 0;
EXCEPTION
WHEN OTHERS THEN
retcode := 2;
END TEST;

Modify the TicTacToeServer /client from deitel How to program

We've been given example code from the deitel & deitel book how to program and have to carry out the following alterations:
a) Modify the TicTacToeServer class to test for a win, loss or draw on each move in the game. Send a message to each client applet that indicates the result of the game when the game is over.
b) Modify the TicTacToeClient class to display a button that when clicked allows the client to play another game. The button should be enabled only when a game completes. Note that both class TicTacToeClient and class TicTacToeServer must be modified to reset the board and all state information. Also, the other TicTacToeClient should be notified that a new game is about to begin so its board and state can be reset.
c) Modify the TicTacToeClient class to provide a button that allows a client to terminate the program at any time. When the user clicks the button, the server and the other client should be notified. The server should then wait for a connection from another client so a new game can begin.
d) Modify the TicTacToeClient class and the TicTacToeServer class so the winner of a game can choose game piece X or O for the next game. Remember: X always goes first.
So far I have only been able to do part a) of the exercise im having a lot of difficulty with part b) which allows the client to play a new game.The code ive done so far is listed below if anyone can help i would be forever greatful. Thanks

Subtle bug in Deitel & Deitel "Java How to Program" book

Merry x mas and happy new year, guys.
I have this applet (which is at the same time runnable and listener) its printed in Deitel & Deitel "Java How to Program" book 3rd ed.
The program works but as you turn on and off the "suspend" checkboxes some of the threads are not notified, so they go to infinite wait state, deadlock. I couldn't figure out what is wrong or how to fix the problem.. please read the code below, or copy and paste this code to your eclipse, its just one file, then play with the check boxes, some of the threads don't wake up after wait... technically they don't shift from WAITING to TIMED_WAITING state.

Abiel wrote:
No, notifyAll() is used to tell the threads that we're stopping.... see that it's written in the stop() method of the applet. Eg if the user browses away from our applet we set the array of threads to null and notify them all. So notifyAll() makes sense.Yes, it does make sense there too (!!!!!!!).
However, I gave it a try with what u suggested, and it didn't work (as expected) .... Apparently you did not really read my suggestion or my explanation. If you had, you'd have expected it to work and it would have worked.
the problems still remains, some threads are getting in wait state even if their check box is not suspended.Maybe you should add the following code to understand the root cause and solution.
    System.out.println("Thread " + index + " will wait to be notified.");
    wait();
    System.out.println("Thread " + index + " was notified.");
what could the problem be?Improper use of notify()

Deitel, Java How To Program exercise question

Hi, :)
I'm new to programming and I'm using the Java How To Program Fourth Edition from Deitel and Deitel as my text. I've run into a problem with Exercise 2.16 Where I'm asked:
"Write an application that asks the user to enter two numbers, obtains the numbers from the user and prints the sum, product, difference, and quotient of the numbers."
From that I have written this code:
// Exercise 2.16
/* An application that asks the user to enter two numbers, obtains the numbers from the use and prints the sum,
product, difference and quotient of the numbers. Using the techniques shown in Fig 2.9 */
//Java extension packages
import javax.swing.JOptionPane;
public class Exercise2_16{
     //Main method
     public static void main(String args[]){
     String firstNumber, secondNumber;                          //introduce variables
     int number1, number2, sum, product, difference, quotient;          //introduce variables
     firstNumber=JOptionPane.showInputDialog("Enter first integer:");     //Create input window
     secondNumber=JOptionPane.showInputDialog("Enter second integer:");     //Create input window
     number1=Integer.parseInt(firstNumber);                         //String to integer
     number2=Integer.parseInt(secondNumber);                         //String to integer
     //perform operations
     sum = number1+number2;
     product = number1*number2;
     difference = number1-number2;
     quotient = number1/number2;
     //Display results
     JOptionPane.showMessageDialog(null, "The sum is " + sum,
     "The product is " + product, "The difference is " + difference,
     "The quotient is " + quotient, "Results", JOptionPane.INFORMATION_MESSAGE);
     //End program
     System.exit(0);
     }//End main method
}//end class Exercise2_16
When I compile this code I get an error and I can't figure out why. Any help is really appreciated as I'm stumped and given the simplicity of the app I'm kinda bummed it has me stuck :(.

I substituted your line and this is the error I'm receiving now:

It doesn't really matter to me if there are returns but maybe for readability there should be and so I learn how to as well.

Error compiling FPGA VI: ERROR:Xflow - Program xst returned error code 6.

When I use the Linear Interpolation function in my FPGA VI i get the compilation error:
ERROR:Xflow - Program xst returned error code 6. Aborting flow execution...
the Compile Server also gives the more detailed information:
ERROR:Xst:1749 - "C:/NIFPGA85/srvrTmp/LOCALH~1/TRAPCO~2/NiLvFxpFloor.vhd" line 68: error: The output for the floor function should not have any fractional bits.
I'll be happy for any suggestions how to solve this.

Hello!
Could you compile a program with only the Linear Interpolation.vi and only some constants and indicator as input and output?
I tried on my PC and compile a simple VI containing only the Linear Interpolation.vi
Which Version of NI-RIO do you use?
Do you also placed the FPGA VI in library? If yes put out all FPGA VIs from the library and check that they aren't reentrant.
This could cause problems to the compiling of FPGA VI.
Try to create a new project with only a VI with the linear interpolation and check if it is compiled.
Best regards
Ken

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

How to trap null return values from getters when using Method.invoke()?

Hi,
I am using Method.invoke() to access getters in an Object. I need to know which getters return a value and which return null. However, irrespective of the actual return value, I am always getting non-null return value when using Method.invoke().
Unfortunately, the API documentation of Method.invoke() does not specify how it treats null return values.
Can someone help?
Thanks

What do you get as a result?I think I know what the problem is.
I tested this using following and it worked fine:
public class TestMethodInvoke {
public String getName() {
return null;
public static void main(String args[]) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException {
Object o = new TestMethodInvoke();
Class cls = o.getClass();
Method m = cls.getMethod("getName", (Class[]) null);
Object result = m.invoke(o, (Object[])null);
if (result == null) {
System.err.println("OK: Return value was null as expected");
else {
System.err.println("FAILED: Return value was NOT null as expected");
However, when I use the same technique with an EJB 3.0 Entity class, the null return value is not returned. Instead, I get a String() object. Clearly, the problem is the the EJB 3.0 implementation (Glassfish/Toplink) which is manipulating the getters.

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?
I basically managed to learn how to invert parameters which allows me to be as default in the clean guitar channel and if I switch the first button on the midi foot controller I switch to crunch, but at this point I tryied so hard to programm the second and third button to switch, only through a button in one step, to a third channel for distorsion or a 4th channel for solo guitar but I couldn't figured out how this work can be done!
I would appreciate if anyone could help or share this experience with others who are experiencing the same problem.
Cheers.

I cannot seem to get mainstage to recognize my FCB either. I am using IFCB. Anyone figure this out?
Thanks,

You can use the Automator app to set an alarm on your calendar which sends the mail at a future time.
It's simpler than it might sound. This explains how:

I want to send 10 bit ADC from PIC via serial communicaton. i send it separetly 8 bit first then the other 2 bit. how to program in labview to capture those two packet then combine it togother

i want to send 10 bit ADC from PIC mCu via serial communicaton.
i send it separetly 8 bit first then the other 2 bit (2 bit --> with zero at 6 bit from LSB).
how to program in labview to capture those two packet and then combine it together
so i have 10 bit in lab view
thank you

Close, but now quite. You need to specify to the VISA Read how many bytes to read, not how many bits. Thus, the input would be 2, not 16. It's also not clear why you're trying to use the "String to Byte Array". The Type Cast will give you a number based on what data type you wired. You're basically telling it how to interpret the string. In this case we're telling it to interpret the string a 16-bit value, so we'll get a 16-bit integer. I know you said you wanted a 10-bit, but you can't have that. You'll get a 16-bit with 6 bits set to zero. Note: I did not completely understand what you said so we may need to change this slightly, but we want to get the communication and reading collection working first.
Also, since you seem to be setting this in a loop you probably want to monitor this or to collect the data. For that you need a shift register. See attached for a modified version of your attempt. You need to set the datatype to I16 or U16 based on whether the value you get from the PIC is signed or unsigned.

How to transfer customr return stock to jobwork ( reapir) vendor

Dear All,
Please let me know -
Suppose i had a customer defective (customer returns)stock in my plant ( which is non valuated stock). I would like to send the same for repair/ service to outside from my plant.
I do not want any valuation / accounting effect while sending the customer defective material outside. So please suggest me-
How to transfer customr return stock to jobwork ( reapir) vendor ? Through which movement type ? GR MvT ?
Waiting for reply.
Thanks & Regards
Mangesh

Hi,
You can send the material using movement type 512 in MIGO using option Goods Issue > Others. And cancel the same material document when you get the materials back from vendor after repair.
Then follow Service Process Cycle for paying the repair charges to vendor
1. ME21N - Create Service PO (With Item Category D and Account Assignment Category K )
2. ML81N - Create Service Entry Sheet w.r.t. Service PO
3. MIRO - LIV for Service Charges w.r.t. Service PO or Service Entry Sheet
For Service Process, refer following link;

I don't know how to program my DVR to edit out the commercials

Does anyone know how to program the DVR not to record the commercials? Its not a problem on public television, of course.

Actually often very easy to do, but we will not see it again. The Industry has fought against it and made all the manufacturers remove such features.
