String date to integer

Need help.
Does anybody know how to convert a string date to int..
format of the date is like this(dd-mm-yyyy) example ->15-Aug-1993.
I would like to convert the corresponding month to int...
like for Jan=1, Feb=2,Mar=3...Aug=8...Dec=12...
is there any method in java which supports this kind of conversion?
sample codes would be of great help.
Thanks in advance.

If your intention is to convert "15-Aug-1993" into "15-8-1993", ie a string->string conversion, use a SimpleDateFormat to parse the first string into a Date. And then use another one to format the date into the appropriate format.
If you want to obtain an integer value from the string according to the scheme you presented, you could parse it as above then use the getMonth() mehod of the Date class. Note: the returned value is zero based (January is zero, not one) and the method is deprecated.
It's better to use the Calendar class:
* Use SimpleDateFormat to obtain a Date (ie parse the string)
* create a Calendar instance and set its time to the date
* use the get() method of Calendar to obtain the month
The Calendar class defines a number of int values: Calendar.JANUARY, Calendar.FEBUARY etc. Mostly you use these values without knowing or caring what int values they have.

How to export the data as integer into excel sheet?

Hi All,
I am working on export to excel functionality and using JEXCEL API to create it. When I export the data to excel sheet, the data are stored in text format in the excel sheet. If I click on summation button on excel sheet, it is not summing up the column values since it is stored as the text format.
I am writing the following code:
for(Iterator iter = columnInfos.keySet().iterator(); iter.hasNext();){
String attributeName = (String)iter.next();
for(int index = 0; index < dataNode.size(); index++){
try{
IWDNodeElement nodeElement = dataNode.getElementAt(index);
String colVal = nodeElement.getAttributeAsTex(attributeName);
Label value = new Label(j, index + 1, colVal);
sheet.addCell(value);
j++;
Here colVal is the variable which holds the data in string format. So I was just trying to convert it into integer format and used Integer.parseInt(colVal).
But Label keyword accepts only the int,int,string arguments.
Is there any other option to change it as integer value while exporting to excel sheet.
Pls suggest.
This is very urgent.
Regards,
Subashini.

Hi Gopal,
Pls refer the following link.
/people/subramanian.venkateswaran2/blog/2006/08/16/exporting-table-data-to-ms-excel-sheetenhanced-web-dynpro-binary-cache
I have used the same coding which is mentioned in this link.
And also I cannot use integer.parseInt(colval) because new Label() will accept only the int,int,string as parameters.
Here goes my to excel method code which exports the data to excel sheet .
private FileInputStream toExcel(IWDNode dataNode, Map columnInfos) {
String fileName = "output.xls";
IWDCachedWebResource cachedExcelResource = null;
int i = 0;
try{
File f = new File("output.xls");
WritableWorkbook workbook = Workbook.createWorkbook(f);
WritableSheet sheet = workbook.createSheet("First Sheet", 0);
for(Iterator coluinfoitr = columnInfos.keySet().iterator(); coluinfoitr.hasNext();){
Label label = new Label(i, 0, (String)columnInfos.get(coluinfoitr.next()));
sheet.addCell(label);
i++;
int j = 0;
for(Iterator iter = columnInfos.keySet().iterator(); iter.hasNext();){
String attributeName = (String)iter.next();
for(int index = 0; index < dataNode.size(); index++){
try{
IWDNodeElement nodeElement = dataNode.getElementAt(index);
String colVal = nodeElement.getAttributeAsText(attributeName);
Label value = new Label(j, index + 1, colVal);
sheet.addCell(value);
catch (Exception e){
wdComponentAPI.getMessageManager().reportException(" Data Retrive Err :" + e.getLocalizedMessage(),false);
j++;
workbook.write();
FileInputStream excelCSVFile = new FileInputStream(f);
cachedExcelResource = getCachedWebResource(excelCSVFile, fileName, WDWebResourceType.getWebResourceType("xls", "application/ms-excel"));
wdContext.currentContextElement().setExcelDownload(cachedExcelResource.getURL());
workbook.close();
It is exporting the data in text format. So I am unable to sum up the column values in the excel sheet.
I need an alternate solution wherein I can export the data in integer format to excel sheet and then sum up the column values by clicking on summation button.
Hope I am clear now.
Pls suggest.

Subashini.

Coverting from a string to an integer

Hi:
Is it possible to covert a string to an integer?
For example I want to convert the following string values to integers so that I can develop a method to use java.util.Date to test for overlapping appointments.
Ex:
markCalendar.addApp(new Appointment("June 1","3pm","4pm", "dentist"));
I want to convert the startTime and the endTime to integers. And compare the startTime and endTime to a vector of appointments.
Should this approch work?
Thanks.

Hello,
First I would like to suggest, DONT use the class names that have already being defined in JAVA, Here you have used, CALENDAR class, this approach should be avoided, If this class is in the same project where you also want to use the JAVA CALENDAR class, then you mite not be able to do so.
As for the conversion, A simple way is that:
You already know that the time cannot go more than 2 digits (Specifically not more than 24 hours in case of hours and 60 in case of minutes) and the (am) (pm) takes 2 more places, so what you can do is validate if the string size is 4 or 3, if 4 then take the first 2 substrings i.e. somestring.substring(0,2) and then use the Ineteger.parseInt(some string) method.
similarly if the String size is 3 then take the first substring
e.g. somestring.substring(0,1)
This is how you can convert the string to the Integer and compare it, You can store it as an Integer Object and store it in the Vector If you want to.
Hope this helps

Rohan

About string data type

Hi
Maximum number of characters that a string data type accepts in Java.
Thanks..

The next may give a rough test.
public static void main(String[] args) throws Exception{
int factor= Integer.parseInt(args[0]);
char[] data = new char[Integer.MAX_VALUE/factor];// note: integer division
for(int k=0;k<data.length;k++) data[k]=(char)0x30;
String s=new String(data);
System.out.println(Integer.toString(s.length()));

Look for something more consistent. A pattern.As I said earlier, it depends if he wants an object or a primitive.

Minus date in string data type

Hi all,
i having one table in database that used to store the borrow_date and return_date, the date is in this format 06/12/2008, when i retrieve the date from the database, and i pass it into String data type, for example as follows:
private String borrow_date = 05/12/2008;
private String return_date = 10/12/2008;
if for example student A return the book on 15/12/2008, which is after the return_date in database, then i want to minus is 15/12/2008 with 10/12/2008, so that i can get the int value of 5 days. Because i want to use this integer 5 for late penalty. One day charge for 20 cent.
e.g: String borrow_date - String return_date = int total_days;
Now my problem is this, i dont know how to use string data type minus with string data type to get the integer type.
I had tried for many methods already, still cannot get it, i can get the total days in int data type if the date is in Date or Calendar data type. The problem now is the date is in String data type. Any idea from you? :)

because in my case, i have to use string data type :)Thinking about this again, it really is stupid. You say you are even storing the dates in the database as Strings and not Dates. It can only lead to a world of hurt.

The "write key" configuration file vi use of "trim string" prior to writing the data can modify any string data written.

I tried to use the config VIs to record some front-panel settings for later restoration, one of which could be a single space character (part of a string parsing system).
I soon discovered that whenever I tried to save that single-space value to an INI file, only a null string was saved.
After doing some digging I discovered that buried in the Write Key vi is a worker vi called Config Data Modify that uses Trim String on the string data before it is written to the file and that's what was eating my string character. I don't know whether this is a bug or a feature but there are at least three ways to fix it.
1) Assuming you want to leave the library VIs alone, you can pre-process any stings sent to "write key" to replace all spaces with "\20" and then post-process all strings read using "read key" to replace all instances of \20 with spaces.
and if you don't mind modifying the library VIs, either to save/use under a different name or to stick back into the library in a modified state (caution - can cause problems when you move code to another machine with an un-modified library) then...
2) You can yank the trim-string out of the Config Data Modify vi and hope that it does not have any undesirable side effects with regards to the other routines that use Config Data Modify (so far I have not found any in my limited testing)
or
3) You can modify the string pre-processing vi, Remove Unprintable Chars, to add the space character to the list of characters that get swapped out automatically.
Note that both option #1 (as suggested above) and option #3 will produce an INI file data entry that looks like key="\20Hello\20World\20" while option #2 produces an entry that looks like key=" Hello World "

Hi Warren,
there's a 4th option:
Simply set the "write raw string" input of the write key function to TRUE
This option only appears when a string is wired to that function!
Just re-checked:
I think it's a limitation of the config file format. It's text based and (leading) spaces in the value are "overseen" as whitespaces. So your next option would be to use quotes around your string with spaces...

Need to convert string data to numbers.

I have string data that I need to convert to numbers so that I can graph it or perform calculations on it. The data (file attached) is in three columns (tab separated) and is in the format time/double/time (saved as a string with Write haracters to File.)

Report Builder Error: [BC30455] Argument not specified for parameter 'DateValue' of 'Public Function Day(DateValue As Date) As Integer'.

Hi there!
I'm trying to calculate the difference between two days using DATEDIFF (). I use following code for this:
=DATEDIFF(DAY, CDate(Fields!Eingang_Kundenanfrage.Value),CDate(Fields!Ausgang_Angebot.Value))
Every time I try to save the report, I get this error message:
[BC30455] Argument not specified for parameter 'DateValue' of 'Public Function Day(DateValue As Date) As Integer'.
The DataSource is a SharePoint List and the Date is given in the following format: 23.05.2014 00:00:00 (DD.MM.YYYY HH:MM:SS).
I've googled for a working solution for a long time now, but I had no success.
Is there someone who can help me?

Hi Lucas,
According to your description, you want to return the difference between two date. It seems that you want to get the days. Right?
In Reporting Services, when we use DATEDIFF() function, we need to specify the data interval type, for days we can use "dd" or DateInterval.Day. So the expression should be like:
=DATEDIFF(DateInterval.Day, CDate(Fields!Eingang_Kundenanfrage.Value),CDate(Fields!Ausgang_Angebot.Value))
OR
=DATEDIFF("dd", CDate(Fields!Eingang_Kundenanfrage.Value),CDate(Fields!Ausgang_Angebot.Value))

If you have any question, please feel free to ask.

Smartform Problem in Displaying a string data

Hi Friends,
I am facing a problem while displaying a string data in smartform. Actually it is a one of the field's data in an internal table. It is a STRING field type of length 0. While populating in an internal table it is having a all the data(Around 700 char data). But while displaying in a smartform surprizingly only few characters(Around 225 char data). How can i overcome this problem?

Hi
try this and see
Declare some Variables of 72 char each and split that long string data of internal table text field into them and display these variables strings one below other in smartform
var1 = itab-text+0(72)
var2 = itab-text+72(72)
var3 = itab-text+144(72)
like that
and display one below other in smartform.

Dynamic structure of "string" data type. Please help.

ABAPers,
I am calling cl_alv_table_create=>create_dynamic_table method to dynamically create a structure. The input structure definition is as follows:
data: xfc type lvc_s_fcat.
data: ifc type lvc_t_fcat.
* define Fld1
clear xfc.
xfc-fieldname = 'Fld1'.
xfc-datatype = 'string'.
append xfc to ifc.
* define Fld2
clear xfc.
xfc-fieldname = 'Fld2'.
xfc-datatype = 'string'.
append xfc to ifc.
Although the call to create_dynamic_table does not throw any exceptions, it appears Fld1 and Fld2 are not of "string" data type. I don't know of a way to see what type they are. However, they do have a length limit of 10 characters.
After some experimenting, it turns out that the method simply ignores "datatype" value if it doesn't understand it and creates the field with some default data type.
I would appreciate it if someone can show me how to create fields of "string" data type.
Thank you in advance for your help.

That's right, use STRG as the datatype. Please see the example program.

clear xfc.
xfc-fieldname = 'Field1' .
xfc-datatype = 'STRG'.
append xfc to ifc .
clear xfc.
xfc-fieldname = 'Field2' .
xfc-datatype = 'STRG'.
append xfc to ifc .
* Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
    exporting
      it_fieldcatalog = ifc
    importing
      ep_table        = new_table.
assign new_table->* to <dyn_table>.
* Create dynamic work area and assign to FS
create data new_line like line of <dyn_table>.
assign new_line->* to <dyn_wa>.
assign component 1 of structure <dyn_wa> to <fs>.
<fs> = 'This is string 1'.
assign component 2 of structure <dyn_wa> to <fs>.
<fs> = 'This is string 2'.
append <dyn_wa> to <dyn_table>.
* Write the values of internal table.
loop at <dyn_table> into <dyn_wa>.
    do.
      assign component sy-index of structure <dyn_wa> to <fs>.

Xy graph in GUI. Show string data related to a X,Y point

http://forums.ni.com/t5/LabVIEW/Text-overlay-annotation-onto-an-intensity-graph/m-p/883438/highlight...
Another option might be just to use the cursor functionalities of XY graphs, although they don't hover at mouse position.
Other than that I had a similar request on Image Displays with IMAQ (Vision Development Module) where it turned out that using a simple string control from the classic palette that you move around according to mouse position is an efficient way to let information hover wherever you want.
