Printing out char data type - unexpected results

Hi, I have just started programming, and my first language is Java. I'm using JDK6 update 1.
Scenario 1: - When I do System.out.println(string1 + string2); where string1 and string2 are String variables, the result is as expected.
Scenario 2: - When I do System.out.println(string1 + char1); where string1 is a String variable and char1 is a char variable, here also the result is as expected.
Scenario 3: - But when I do System.out.println(char1 + char2) the output is some numbers (I got output 22 when char 1 is 'P' and char2 is 'I').
Could someone please explain scenario number 3? How do I achieve a concatenated output of multiple chars?
Thanks.

Thanks, so if I understand this right, the + operator works for Strings but is not meant for chars. When I think about it now, it seems right, because a char will always ever be only one character, and never more than one character.

Print out for movement types

Hi Friends,
How to configure print out for movement type 561 or for scrap ?
Can you pl tell me step by step where and how to configure?
Appreciate your help.
Thanks,
Venkat

Hi Venkat,
What you want to print. if you only want to print out the transaction done thr movement type 561. If you are not going through any development then follow the under mentioned process :
Go to MB51- Select the material, Plant & storage location- put the movement type 561 & 562- select the ranges of date- execute it. System will give the report. Then for print out go to List tab and select the print. After clicking on the print tab, you have to fill some informations like- Output device- Put Locl then No of copies-then click on continue. System will give you to select the printer. Just select and print.
If this is enough then ok otherwise inform me.
Hope this will clear your issue.

How to print out a date from the past

I am trying to print out a date from the past but I cant seem to get It,
Lets use for example Independece Day,
How would you write the code in order to print out that exact date?

Look at the
[url=http://java.sun.com/javase/6/docs/api/index.html?
java/util/Date.html]Date APIActually the Calendar class would be better to use, since you can set all the different fields from year to second, plus things like day of week, day of month, week of year, etc.
too slow

Print out a Date in a format I want

Now if I print out a Date object, I will get something like "Sat Jan 01 00:00:00 CST 2005", but what I want is "1/1/2005". I tried to use the get methods to get the month, day, and year so that I can put them in a format I want. However, all the get methods have been deprecated. What will be a possible(maybe easy as well?) way to do it? Thanks.

Something like:
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
public class Test {
    public static void main(String[] args) {
        DateFormat df = new SimpleDateFormat("d/M/yyyy");
        Date now = new Date();
        System.out.println(df.format(now));
        // new for Java 5.0 - almost the same format
        System.out.printf("%te/%<tm/%<tY%n", now);
}Note: If you're using Java 5.0, then you can use the new printf method for PrintWriters. However, this doesn't appear to have a formatting token for single digit months.

Initialization for char data type?

I observed that as String I can declare something like this:
String str = ""; but for char data type, if I declare:
char ch = ''; the compiler will have an error: "empty character literal". So how can I fixe this problem when I want to initialize my char variables as "empty"? Anyone got an idea?

Strings (and StringBuffers/Builders) are collections* of characters - so it makes
sense to be able to refer to a String with precisely zero characters. But char is not a collection of anything - it has whatever value it has and can never
be empty.
*collections with a small 'c'.

How to call VC++ dll whiich return char[] data type value in powerbuilder

Hi Everyone,
I am using PowerBuilder 11.1 build 8123.
I am calling VC++ DLL in our PowerBuilder application which return char[] data type value.
I just declare Global External Function:-
     Function char getOSSectionName() library "DocServClient.dll" alias for "getOSSectionName;Ansi"
And then call this function in window as:-
     Char      ls_section[1] = 'DOCAPPLICATIONS9X'
     ls_section[1]=getOSSectionName()
When I check ls_section[1] value in messagebox it display a symbol (please check attached attached image.)
VC++ function and return variable declaration:-
     __declspec(dllexport) char * __stdcall getOSSectionName()
       char    SectionName[_MAX_PATH];
Please let me know that my code is valid or not.
Please help..

Hi,
Thanks to Everyone for your suggestions.
I am solved my problem to change VC++ function as :-
     Int __declspec(dllexport) __stdcall getOSSectionName(char* SectionName)
                    instead of
     __declspec(dllexport) char * __stdcall getOSSectionName()
and declare global function as:-
       Function int getOSSectionName(Ref char ls_section[100]) library "DocServClient.dll" alias for "getOSSectionName;Ansi"
and call function in window as:-
     int li_ret
     char ls_section[100]
     string ls_sec
     li_ret=getOSSectionName(REF ls_section)
     ls_sec=ls_section

Does CHAR data type work with Forms 11g

We have an application in Forms 11g (32bit - version 11.1.2.0.0). DB is a Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production.
When our Forms calls a stored procedure which has parameters defined using column name type (i.e. like p_customer_code customers.code%TYPE ) and if the column data type is CHAR we get a run time error when executing the package (ORA-06502: PL/SQL: numeric or value error string).
When we change the data type of the tables column to varchar2, it works??
Problem is we have dozens of tables with CHAR data type columns and we can't do all the changes manually. For one thing, if they are part of a primary or unique key or even foreign key, we can't change the data type of the column without dropping the constraint.
What is the solution to this pls??

When our Forms calls a stored procedure which has parameters defined using column name type (i.e. like p_customer_code customers.code%TYPE ) and if the column data type is CHAR we get a run time error when executing the package (ORA-06502: PL/SQL: numeric or value error string).this might also be related to compile settings, check your NLS settings (NLS_LANG, NLS_LENGTH_SEMANTICS) both times when you compile forms AND your stored procedures.
As for the CHAR datatype: CHAR internally is treated like a blank padded varchar:
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:1542606219593
Speaking of that it might be time to use varchar2 instead your char columns. You'd have to drop and recreate your constraints, but with the help of the data dictionary (+user_tables+, user_tab_cols, user_cons_columns, user_constraints) and dbms_metadata this shouldn't be that hard.
Also you'd of course need to recompile all your forms after you are finished, but I guess you are aware of that ;)
cheers

How do I get the system to print-out a date at the bottom of page?

When I am at a website and ask for a print-out of the page -
the current date and time of print-out no longer appears at the lower right corner of page.

I have resolved the problem. I will not use your time attempting to explain the process of elimination. However, the end result---
I had taken delivery of a new printer mid-January - it is a HP OfficeJet 6000 (E609) - I wondered if that might be the problem - since I could not ascertain exactly when the print-out problem had presented itself.
O.K. I logged on to the system and brought up the "Google" page to ask for a print-out. I checked for a print - and when the print box appeared I checked on "properties". That showed - to the left: "General Everyday Printing" and over to the right: Page size "A4 210 x 297mm" also the option "letter 8.5" x 11" and Legal 8.5" x 14" - so, I changed it to ask for the "letter - 8.5" x 11" - then I checked to "print" - I believe it was the "OK" - and the "Google: page was printed intact - showing the data generally associated with the top of the page and the date/time at the lower right.
I placed a telephone call the HP this morning to ask them about the "A4" option and was advised that it is a "standard size paper" - but could not explain under set of circumstances it would be applicable.
Hopefully, this data will be helpful to someone - thank you very much for your assistance in this matter.

Dates in BEx query coming into designer as a dimension with Char data type

This must be an old issue with a well documented work around ... but alas i can find it !
When i build a universe over a BEx query with dates the universe designer builds them as Dimensions of CHAR type not DATE. Therefore all WebI date functionality fails .. eg sorting, automatic time hierarchies etc.
What is the workaround ?
Andrew Fox

Is the data source an InfoSet or an InfoCube? It appears the date type object has not been implemented yet for Infosets. Here's SAP Note 1370410:
Symptom
Infoset date type objects (DATS type) are mapped as Character types in a universe based on a SAP BEX Query.
Prompts related to the Date field variables are coming as List of values instead of Calendar in WebIntelligence.
Reproducing the Issue
Create a BusinessOjects universe on a Super Query which is based on a multiprovider containing an Infoset or
Create a BEx superquery directly on Infoset.
BusinessObjects Enterprise XI 3.1
SAP Integrated Solutions Kit XI 3.1
Cause
This behaviour has been considered as an enhancement request and tracked under ADAPT01229917.
Resolution
This enhancement request is scheduled to be addressed in Service Pack 3 (SP3) for BusinessObjects Enterprise XI 3.1 due approximately April 2010.
I did try a BEx query that uses an InfoCUBE as a source and the objects are coming into the universe correctly as dates.

When I print out photo thru iPhoto, the result is too dark.

Hi all,
I have a problem with printing a photo via iPhoto recently.
I remember when I used iPhoto 9 to print out some of my photos but at that moment the result was pretty OK to me.
However, I don't know exatly when but I guess it could be since I upgraded to iPhoto 10...
Everytime I tried to print out some of my photos from my iPhoto library, the result is way too dark than its original color.
I am using HP Photosmart device(C410ㅁ) with fuji photo papers.
I tried to change several options like color sync or printing quality but NO use!!
Strange thing is that if I use airprint with my iPhone or iPad, color level seems to be OK.
But again, iPhone airprint doesn't give any options to manage printing quality level, it couldn't mitigate my problem, either.
Is there anyone out there who has the same or similar problem just like me?
Please share your knowledge to solve this issues.
Thanks in advance
Luke.

What is the color profile of the photo?

Line incomaptibilty betwwen RAW and CHAR data types in SAP Unicode System.

Hi Gurus,
I am working in SAP Unicode system.
We have transferred the standard programs for Non-Unicode to Unicode system.
In one standard function module, <table name> is defined in TABLES parameter as a type of TLINE structure, which has two fields - one is 132 length CHAR and other is 2 length CHAR.
In the same function module , one subroutine is being called, for which <table name> is passed.
But in the FORM of subroutine, this table is defined as a type of HLINE, which has only one field - 134 length RAW data type.
So due to confilct in data types ( CHAR and RAW ) , I am getting an error that both data types are not line compatible.
Do i need to use casting concept to remove the error.
Please suggest me the way to handle this.

hi,
declare the table as same data type.
dont go for any other types.
if you still want the form table as HLINE, then before the form call declare a varibale with TLINE data type pass the values to HLINE.
i think this will be little complex, because again it will be type incompatablity.
we can forcefully pass the values to HLINE with a class.
but i think no need, declaring with same data type might be easy.
Thanks
Vinod

Use same report to print out different data sources on the fly.

Post Author: Lady101
CA Forum: Data Connectivity and SQL
We have 10 reports use diferent datasource( use views with different joint tables), but their print out format are identical. Is there a way to just use single report to run those 10 reports dynamically(the report can point to the right data source on the fly)? So that we can just change single report format when report format needs to be changed. Right now we have to change 10 reports format one by one.

Another option would be to make a single pass in the Source Monitor and save a bunch of subclips. Here's a thread discussing keyboard workflows: Re: Question on making many Subclips in a fast way
If you name highlights with one base name and lowlights with another, it would be easy to drop each batch into its own sequence.
