Can the main return a value?

is there a way for the main to return a value?
possible something with the concept like public static void main -> public static int main?
(it has been tested and doesnt work)
i would like to have the main return an integer or boolean value.
help plz?
rwer

System.exit(some_number);
doesnt work, it doesnt even compileIt does if you use it correctly. Apparently you didn't, or literally coded 'some_number' instead of taking it as an example.
and im pretty sure System.exit is a void functionSo? It ends up setting the process's exit code, so that the caller of the process may get that value.
I just want to know if its possible to return a value
from the main
changing "void main" to "int main" and having a
return 0; something that looks like
public static void main(String[] args) throws
Exception {
return 0;
will compile but will not run, im just looking for
ways to do this, any help would be nice...As stated before, no. But since the JVM is the one who calls main() and isn't going to do anything with such a return code, what good would it do?

SAP Web Service error text : The database returned a value containing an error , type CX_SY_OPEN_SQL_DB

Hello Guru's,
we are creating sales order in SAP from a quote created in .NET, through Web Service created in SAP, and consumed in .NET.
When ever a order is created in SAP for a given quote, SAP returns the sales order number to .NET.
Orders are getting created as expected, but once in a while we are getting the following error from webservice :
Web service processing error; more details in the web service error log on provider side (UTC timestamp 20140609173429; Transaction ID 4DFCEFE33301F1EBB5CE00155D0B4530)
But the problem is order is getting created in SAP for the perticular quote for which we are getting the above error and this order number is not getting returned to .NET.
Upon analysis in TCODE SRT_UTIL for the above transaction ID, has the following details , which are hardly help full to resolve the error.
----TYPE                                  CX_SY_OPEN_SQL_DB
----ERROR_TEXT                   The database returned a value containing an error
----CX_SY_NO_HANDLER
-----CLASSNAME                     CX_SY_OPEN_SQL_DB
This Exception raised by Web Service application
Could you please help in resolving this issue or alteast provide an approach for the same.
Thank you,
Suresh.

Thank you Bhaskar,
How can we clarify whether the error is from SAP or Web part.

Unable to activate DTP - The database returned a value containing an error

Hi Experts,
I want to upload a flat file from local PC to Infocube. I have created everything as expected.
I have created the data source and it is displaying file contents when I do Preview.
But when I try to Activate DTP it gives me following error: -
The database returned a value containing an error
Message no. RS_EXCEPTION000
Can somebody tell me if this is a basis error ? If yes then what corrective action have to be taken to resolve this.
Thanks a lot.
Best Regards,

Hi PT,
I did not have any routine in the transformation but on double clicking time characteristics (0CALMONTH and 0CALWEEK ) I saw that check box "Perform" was checked so I unchecked that and reactivated the Transformation once again.
I deleted the DTP and recreated but the problem still persists.
Any more inputs on this ??
Best Regards,
Chandan

How can I remove the iPhoto upgrade to my iMac OSX 10.2.8? Can the upgrade return my library?

How can I remove the iPhoto upgrade to my iMac OSX 10.2.8? Can the upgrade return my library?

With respect, we'll need rather more detail than that.
In general, you can only roll back an upgrade to a library with a back up. No back up, no roll back.

Can F4IF_INT_TABLE_VALUE_REQUEST FM return a value in a global variable?

Hi everybody,
I need to use F4IF_INT_TABLE_VALUE_REQUEST FM because I have to let users select an specific option before choosing another value. The point is that I need to save in a program global variable what the user selects, and decide something with it in the program.
Is it possible that F4IF_INT_TABLE_VALUE_REQUEST FM returns the value in a sinple variable or it has to be paramter?
I look in a lot of previous threads but I didn't find anything, and I don't know if it's possible.
Thanks and kind regards,
MMP.

Hi,
Sure you can. All you need to do is to store what the function returns in your global variable. It don't need to be returned back to screen field.
DATA: BEGIN OF VALUES OCCURS 0,
         CARRID TYPE SPFLI-CARRID,
         CONNID TYPE SPFLI-CONNID,
       END OF VALUES.
DATA: VALUES_TAB TYPE TABLE OF VALUES,
          G_VALUE TYPE SPFLI-CONNID. "global variable to store what is returned
"in PAI first populate your table
SELECT CARRID CONNID
    FROM SPFLI
    INTO CORRESPONDING FIELDS OF TABLE VALUES_TAB
    UP TO 10 ROWS.
"then call the function but don't return the value to screen field
"If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the useru2019s selection is
"returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the
"selection is returned into the table instead.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            RETFIELD         = 'CONNID'
            VALUE_ORG        = 'S'
       TABLES
            VALUE_TAB        = VALUES_TAB
            RETURN_TAB      = RETURN_TAB.
"now simply read first row of return tab and store the value returned there in some global var
READ RETURN_TAB INDEX 1.
MOVE RETURN_TAB-FIELDVAL TO G_VALUE.

Can a function return two values???

Hi guys can a function return more than values?

Or even better return an Object.
ie
public class Tester{
     public static Multi getM()
          Multi m=new Multi();
          m.x="testing";
          m.y="new value";
     public static void main(String [] args)
          Multi mt=getM();
          System.out.println(mt.x);
          System.out.println(mt.y);
     class Multi{
          public String x;
          public String y;
}

Can a procedure return a value

Can a stored procedure return a value or will that generate an error, do you have to change it to a function

You would have to make it as a OUT (IN OUT) parameter if you wanted to return something to the caller from a procedure.

Can java method return multiple values

hey , I need big favor can i return two arrays in a single function

Not directly no.
But there are ways around it.
You can create a "result object" which has attributes being the two arrays, and return that object (ie wrap the arrays in another object)
You could put the arrays into a collection (eg ArrayList/Vector) and then return that object. You can then retrieve the two arrays as the first two items in that list.
Either of those should work, even if they are hacks ;-)

Can the volume slider show value in non-DB?

I remember seeing the volume slider in the channel strip showing normal number values instead of db, but I cannot find a way to changes this. Anyone knows?
André

The worst part is that once you get used to using the db scale, and then open an old song that is set to numbers (MIDI 0-127) there is no way to set it to db. Why ever remove a function?

Can the carriage return within a variant be read as the termination condition for VISA READ?

Hi guys, I am trying to read a variant data using VISA READ. The VISA READ is set to terminate reading when it sees a carriage return.
Is there a chance that for the CR "encapsulated" within the variant be read by the VISA READ, and cause it to terminate?
Cheers!
Solved!
Go to Solution.

Since with the Flatten to String you are basically sending a binary representation of the data, you are going to have problems if you have the termination character enabled since byte 13 would be part of perfectly valid data and not just represent the end of a transmission.
What you might want to do is disable the termination character. Of course now you don't know how many bytes to read. So prepend your message to write with the number of bytes that are a part of the message (string length). You may want to use two bytes, (one byte would only give you messages up to 255 characters in length.)
Now on your reading end, read 2 bytes, convert them to a number and feed that number in the next VISA read which will then read that many bytes.
For examples, look at the TCP/IP read write examples in the example finder and you'll see how they send a message with 4 bytes to tell how much data makes up the rest of the message.

Can the main user name be changed?

I set up a MacBook (Aluminum) for my wife Marge as the user. She no longer uses it, so I have changed the admin account to my name, but I don't want to chage the user to my name without checking first.

Here's the instructions from Apple Support on changing the User Name http://support.apple.com/kb/HT1428 I've done this a couple of times on used MacBooks that I've bought.

Can oracle function return more than one value

Hi All
please answer can oracle function return more than one value
need one schenario
regards

Can any function, irrespective of the language, return multiple values?
OF COURSE NOT!!
So why do you think Oracle will now suddenly do it differently than all other languages? Never mind that it is impossible for a function (a unit/module of code) returning a memory address, to return multiple memory addresses. The machine code that does that, has not been yet been designed/implemented.
I am continually amazed that this question is asked. It is about something so fundamental in almost every single 3rd and 4th generation language... something that is taught right at the start... the definition of what a procedure and what a function is.
Sorry, but I simply cannot pull punches on this subject and smooth it over. There is something fundamentally wrong with your training as a programmer if you have to ask such a question about a function.
And whatever programming skills you build on such a foundation, will be seriously lacking.
I kindly suggest that you get back to the very basics of programming - and review and revisit until you fully understand it. There are no shortcuts in becomming a good programmer.

Whee the function return the value store in java

in c if i write this program
int add()
return 1;
main()
add();
if i run this program it give s error that lvalue required
but in java it works fine though the function return some value

in c if i write this program
int add()
return 1;
main()
add();
if i run this program it give s error that lvalue
requiredYou mean, if you try to run it as a C program it gave an error?
Then take your question to a "C" discussion forum. This is Java.

but in java it works fine though the function return some value
In Java this does NOT work fine.
It definitely does not compile! So you cannot run it.

Error while activating DTP : database returned a value containing an error

Hi ,
I am getting an error as "The database returned a value containing an error"
while activating the DTP. Can neone suggest any solution for this error .
The system is also not allowing to delete the DTP and giving the same error as above one .

Are you receiving a similar error as below from the log:
Creation of PSA /BIC/B0001995 failed
Error during creation of DDIC sources of Data Transfer Process DTP_4DGGKC0NCCP394FEOOSQC68Y3
If yes then look into SAP Note 1145673 - Extracting from InfoProviders with navigation attributes. Application of this note should resolve the issue.

Can a method return a class ?

hi,
i have a simple question.
can a method return class value ?
in the below script i did'nt understand the commented line.
package com.google.gwt.sample.stockwatcher.client;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath("login")
public interface LoginService extends RemoteService {
public LoginInfo login(String requestUri); //What is this ? is this a sample of what i asked ?
}

The answer to your question is yes.
The idea is that an object calls a function of another object (passing in objects to the function as arguments) in which that object returns an object (note the arguments or returned value of the function may alternately be primitive types). Each object typically encapsulates data and provides a rich set of functions to the calling object so that calling object doesn't have to deal with the raw data directly. Therefore, not only does the calling object get the data it wants, but also a rich set of functions that can manipulate that data.
Example:
Book book = new Book();
int characterCount = book.getChapter(3).getParagraph(4).getSentence(12).getWord(8).getCharacterCount();
In the above, each object (Book, Chapter,Paragraph,Sentence,Word) has a rich set of functions it provides to its caller.
Example: the Sentence Object has a collection of word objects (raw data). Functions it provides to Paragraph object are:
Word getWord(int index), Words getWords(), int getWordCount().
If you haven't already done so, I suggest reading a book on Java from cover to cover to pick up such Object Oriented concepts.
