Convert a calendar object to a date object

hi all...i use a calendar to select date and i want to convert the Calendar object returned to a date object ..how could i do that ?? i use the following lines of code but the Date object returned is not correct ..i mean it's not the one i chose from the calendar
Date selectedDate=new Date();
selectedDate=(calendar1.getTime());
Any one could help....thank you

Show us the code where you set the calendar to your desired value. Calendar1.getTime()
should return the relevant date.

Difference between Service data objects and process data object

Hi
Can anybody tell me what is the difference between SDO (Service Data Objects) & PDO (Process Data Objects).I am using 2 port PCI-CAN series 2 card.
If anybody knows the answer then please reply.
Thanking You

Hi,
See the online help file from our NI CANopen Library for LabVIEW for some basic informations about SDOs and PDOs.
More information should be available from the web.

Read attribute value of a master data object's master data object

Hi Guys,
I have a peculiar condition where I need to read attribute value of a master data object's master data.
Requisition (ZREQUI) is linked to Candidacy (ZCDCY) by object called Recquisition.
Candidacy (ZCDCY) is linked to Candidacy Activity (0CDCY_ACT) by object called Candidacy.
I want to populate attribute called due date in ZREQUI by reading lowest value of due date value of 0CDCY_ACT. There can be multiple hits.
If I can get the code to do this, I would really appreciate it.

Here is the outline of the code ,as per my understanding..chk if it can help u
In start routine write a select statement to pick all the data from 0cdcy_act.
select 0CDcY_ACT ZCDCY DuE_DATE from /BiC/P0CDCY_ACT
into table itab1
for all entries in source_package
where ZCDCY = source_package-ZCDCY.
as you need the lowest due date, sort the iTAB1
sort itab1 by due_date ZCDCY. (default is acending order)
In the field routine of your due date
Read table itab1tnto wa_itab1 where
ZCDCy = source_fields -ZcDcY.
now duedate = wa_itab1-duedate.

Comapring two Calender Objects for same Date object

hi,
I am having problem with Comparing two Calender Objects which is having same Date value but time stamp is not same.when i printed as Calender.getTime()---->i found them as.
Cal1----->Wed Feb 28 20:26:29 IST 2007
Cal2------>Wed Feb 28 00:00:00 IST 2007
Now the method:
While(Cal1.getTime().compareTo(Cal2.getTime()) ==0 ) is Evaluating false.
i dont want to be concerned with time stamp.i want condition to be true.
Please help me .thx in advance.
Cheers
Akash

My comment was directed at the fact that you gave the same answer I did, only faster. There is no other way I am aware of that will be any quicker. Of course, that is looking at a small piece of code out of context, so there may well be a better way.

Convert Date Object to Calendar object

Hi,
I have a Date field in my webdynpro application, I need to to read this from my current context and convert the same to a Calendar field and pass it to my model.
Calendar date = CalendarConverter.parseDate(req_date.toString());
The above code gives me a null pointer exception.
Can anyone suggest me the right way of converting a Date object to Calendar object?
Ashwini.

Ashwini,
try to use the following code snippet:
// get calendar and set your date object
Calendar c = Calendar.getInstance();
c.setTime( <YOUR_DATE_OBJECT> );
// to manipulate the fields use this
c.set(Calendar.MONTH, 1);
// to manipulate retrieve a fields use this
c.get(Calendar.MONTH);
Hope that helps you.

Adding days to a date object

I am retreiving a date field from the database.
i am retrieving that with getDate() method on the result set object.
that is am retrieving as java.sql.Date object.
on that date object i have to add 30 days and store it back in the
database as a date field in database.
How should i go about handling this problem.
suppose
java.sql.Date newDate=rs.getDate(1);
on this newDate how can i add 30 days and store it back to the database.
Plz help me out guyz.
Thanks.

wud the setting to a particuale date means setting to
the date i retrieved from the database.
How to set for a particular date.We have setTime()
method in Calendar.
but that takes util.Date object.Then do i have to
convert the sql.Date object into a util.Date object.A java.sql.Date IS-A java.util.Date.
(There's no such thing as a sql.Date or a util.Date unless you have a different API than the rest of us.)

Problems with Date objects

I want to use the HttpSession.getCreationTime() value and write it to an Oracle Date field.
I am having trouble getting the value in the proper type and format.
I have a test servlet to try to understand the various ways to use and convert DateTime values.
Here's the code:
response.setContentType("text/html");
java.io.PrintWriter out = response.getWriter();
HttpSession session = request.getSession();
long logontime = session.getCreationTime();
SimpleDateFormat formatter = new SimpleDateFormat("mm-dd-yyy hh:mm:ss");
java.sql.Date sqlDate = new java.sql.Date(logontime);
String sDate = formatter.format(sqlDate);
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet</title>");
out.println("</head>");
out.println("<body>");
out.println("DateTime in Milliseconds: " + session.getCreationTime() + " ");
out.println("DateTime as java.sql.Date: " + sqlDate + " ");
out.println("java.sql.Date SimpleDateFormat: " sDate " ");
out.println("</body>");
out.println("</html>");
out.close();
Here's the output:
DateTime in Milliseconds: 1016812138284
DateTime as java.sql.Date: 2002-03-22
java.sql.Date SimpleDateFormat: 48-22-2002 10:48:58
What's happening with the Month in the SimpleDateFormat output?
Also,
How can I convert this string into a valid Date Object to use in CallableStatement.setDate(int index, Date x)?
Thank you for your help.

If you have a String that's in that format, and you want to convert it to a java.util.Date, you do something like this:SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy hh:mm:ss");
java.util.Date date = dateFormatter.parse(thatString);Then if you want to convert that to a java.sql.Date, you do this:java.sql.Date sqlDate = new java.sql.Date(date.getTime());However, I suggest you don't actually want to do that. If your date has hours, minutes, and seconds in it then converting to java.sql.Date throws away that information. You may want java.sql.Timestamp instead.

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object
reward if useful

Error while generating Data Objects in sdoe_wb SAP for Basis component

Dear all,
While generating SAP BASIS Components getting error
After installations of SAP Netweaver Mobile 7.1 SP11 and all the Notes applied for SP11 i have done the Generation for all the SAP BASIS Data Objects
All the Data objects are generated except AGENT_CONFIG, ARCHIVE
When i check the same in smq2 it shows the error in Function module SDOE_GENERATE_MBO for the user FUNC001,in status text it shows "connection closed (no data)"
kindly help on this issue.
Regards
Revanth

Hi,
well, I guess if you mean you did reset the queue - you deleted all emtries with error. Try to avoid this in the future - you will get unwanted side effects by that. There are only a few errors that make this behaviour necessary.
Usually you should select the entry on the first screen - so you see the status of the queue on the second one. On there you can select the queue and while pressing the green tick, you can restart it. If it is a timeout - this restart usually helps.
Wondering why you have an issue with basis objects - did you run through the complete setup guide up to this point?
Regard,
Oliver

Data types and Data object

Can Any one give me Clear definition of Data type and Data objects.
Concept i know clearly.. but unable to explain it..

Prasanna

Data consists of strings of bytes in the memory area of the program. A string of related bytes is called a field. Each field has an identity (a name) and a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
 In the ABAP type concept, fields are called data objects. Each data object is an instance of an abstract data type. Data types in ABAP are not just attributes of fields, but can be defined in their own right. There are separate name spaces for data objects and data types. This means that a name can at the same time be the name of a data object as well as the name of a data type.
Data Types:
 As well as occurring as attributes of a data object, data types can also be defined independently. The definition of a user-defined data type is based on a set of predefined elementary data types.

Data Types
Data types are templates for creating data objects. Data types can be defined independently in the ABAP program or in the ABAP Dictionary. As attributes of a data object, data types can also exist in a non-independent state. Data types do not use any memory space for work data, but may require memory for administration information.
As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types.

A data object is an instance of a data type and occupies as much memory space as its type specifies. An ABAP program only works with data that is available as content of data objects. Data objects are either created implicitly as named data objects, or exanonymous data objects using CREATEDATA.
Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type..

About Date object

hi all
I want to add an int object in the date object and wants to return date object
I want to calculate the finishdate using startingdate and no.of days field which i am inputing from the user
please help
if anybody can

hi all
finally i got the solution of my problem
it is like below
int nd=Integer.parseInt(request.getParameter("days"));
          java.util.Date newfdate= new java.util.Date(sy,sm,sd);
          int nd1=nd*24*60*60*1000;
          long nd2=newfdate.getTime();
          long nd3=nd1+nd2;
          //out.println(nd3);
          java.util.Date fdate= new java.util.Date(nd3);
          int finald=fdate.getDate();
          int finalm=fdate.getMonth();
          int finaly=fdate.getYear();
          java.util.Date finishdate= new java.util.Date(finaly,finalm,finald);
          int fnsd=finishdate.getDate();

          int fnsy=finishdate.getYear();

Univer Prompt Date Object

I have a date prompt. The users can enter a date or they can leave the Date as null. If they leave the Date prompt as Null It has to go and fetch all the Data even if the date field does not have any value. The problem here is if they leave it as null then i am running into an issue of Date column comparing it against a NULL Value. Is there a way for me to handle this issue.
-Prabu

Hi,
To get all the dates then you have to create a all object andshould place it in existing lovs. Try like this.
1. In the lovs odf the date object i.e date object-> right click ->clicko n edit lovs -> then a query panel opens for you there modify the existing query to
Select distinct(dates) from ........... to
select distinct(dates) from ................
union
select ' ALL' from dual; ---> where dual is temporary table if back end is oracle. then in date object in universe try with the below synatx as
Date = (@Prompt('<Prompt message>','A',{'Class\Object'},mono,free) or "ALL '' = @Prompt('<Text>','A',{'Class\Object'},mono,free) .
In your case replace all with SIgle quotations.
Cheers,
Suresh Aluri.

Calendar and Date objects

I've got an application that has many Date objects. We frequently have to do comparisons to see if two Date objects represent the same day. I know that I can use a SiimpleDateFormatter to make a String from a Date. I can compare two of these Strings and determine if they are on the same day.
I also know that I can make two new Date objects from the milliseconds in a pair of Date objects, and set the hour, minute, seconds and milliseconds to zeros. Then, the compareTo method to see if the two days match. But, both of these seem like a huge overhead when I have to do it a lot. (Although the objects are called Date, the compareTo matches the milliseconds version, and so two Date objects from the same day do not match unless they match to the millisecond. Not what I want.)
Have I overlooked something that returns a nice int or long "Julian day number" field that is quick?
If I can assure myself that all of the dates were built with a common TimeZone, could I divide by the milliseconds in a day to get a nice day number?

Maybe an example would clear things up.
This is a large scheduling application, with a very complex GUI.
We find out from a database that an activity runs from December 28, 2008 at 10:31AM to January 2, 2009 at 11:45AM.
The first question after we have converted each date/time pair to a Date object is: "On how many days does this activity take place?" In this case it is 6 days Dec 28, Dec 29, Dec 30, Dec 31, Jan 1, and Jan2. This will be displayed in a JTable with 6 columns. The ideal (at least to me) solution would be to get a day number as described above for the start and end, and know that (end_day - start_day + 1) columns are required, and we can write a for loop to go from the start day to the end day. If we use a semi-day value of the (year*1000 +DAY_OF_YEAR) we have a unique number, but it is useless for determining how many columns are needed in a table. The comparison between 2008363 and 2009002 does not produce a usable result.
But, there are related operations as part of a more significant activity. We usually have to decide how many days (columns) does it take to display a group of activities. At this level, we don't care what time of days are involved.
This application is on the desktop of multiple schedulers who will move activities around all day long. We need to be as efficient as possible, since some of the other things are very compute intensive.
In parts of the application we are very much concerned about time of day, (for example, the custom table cell renderer paints a stripe across the cell of each table cell with a length proportional to the time of day start and end) but in other parts, the day is the main concern.
I was bothered by the number of Date to Calendar to String conversions being done, and knowing that Date-to-Calendar is not simple due to time zone issues. I also know that Calendar-to-String conversions are not simple since the SimpleDateFormatter has to dynamically interpret a formatting string.
It looks like I'm just stuck with the way it is, unless the alternative date/time implementation is used. That looks a bit promising.
