Time stamp conversion and graphs from array data
How can you read time stamps and data currently in an text file as an array and split in for display on a graph. I think I need to convert the time stamp back into seconds to do this but not sure how to do so?
If you're using 8.2, the Read From Spreadsheet File VI can read string files. If not, you will need to open the VI and read the instruction on the diagram for how to change it.
Once you have your string array, you can use the VI found here to convert the time column (note - read the thread) and convert the second column using the String to Number functions.
Try to take over the world!

Problem with ArrayLists and writing and reading from a .dat file (I think)
I'm brand new to this forum, but I'm sure hoping someone can help me with a problem I'm having with ArrayLists. This program was originally created with an array of objects that were displayed on a GUI with jtextFields, then cycling thru them via jButtons: First, Next, Previous, Last. Now I need to add the ability to modify, delete and add records. Both iterations of this program needed to write to and read from a .dat file.
It worked just like it was suppose to when I used just the array, but now I need to use a "dynamic array" that will grow or shrink as needed: i.e. an ArrayList.
When I aded the ArrayList I had the ArrayList use toArray() to fill my original array so I could continue to use all the methods I'd created for using with my array. Now I'm getting a nullPointerException every time I try to run my program, which means somewhere I'm NOT filling my array ???? But, I'm writing just fine to my .dat file, which is confusing me to no end!
It's a long program, and I apologize for the length, but here it is. There are also 2 class files, a parent and 1 child below Inventory6. This was written in NetBeans IDE 5.5.1.
Thank you in advance for any help anyone can give me!

double pricBalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.

someObject.doSomething(); // Invoking a reference which is null would throw NPE. -
How do you date and time stamp pictures and videos using a EOS Rebel T3?
I am needing to utilize date and time stamping on videos and photos in my work. The pictures and videos must display time, a date, and reference number. I have gone through the cd, owner's manuel and software manuel and I am unclear if I can perform this function.
While this is a relatively common feature on point & shoot cameras -- where the photo is thought of as a snapshot to document a memory in a person's life, among DSLR cameras it's not very common (I don't actually know of a DSLR that does this though I don't doubt that it may exist). DSLR users are usually expecting a higher quality image -- so now the image is thought of more like art and less like a snapshot and the date/time in the corner distracts from the image. Also they tend to be more advanced users who would be able to modify the image themselves so they have little need for such a feature.
The camera does record the date & time... but it's in the EXIF data (information recorded into the image file but not displayed).
SO... there are programs that will just do this. You'll need to do a search (I found several but have never tried one so I can't vouch for them). I think there are Photoshop plug-ins that do this (assuming you have Photoshop). These programs allow you to define the info you want printed (including EXIF data such as date/time) and you get to pick the location, font, size, color, etc. and ultimately the location on the image where you'd like the info displayed. They then add the info visibly onto the image for you and most support "batch" use (e.g. drop a whole folder of images on it and they'll do them all.)

Date time stamp to be converted into only date
Hi Experts,
when i am using substirng functoin for converting datetimestamp to date it is giving the following error
i am using RNIF pip to be converted into IDOC ORDERS 05
the time stamp value from pip should modified in that so that i can get only the date
by elemiting the time asscioated with it so i used substring functoin it is giving following error
/ORDERS05/IDOC/E1EDK02/DATUM. The message is: Exception:[java.lang.StringIndexOutOfBoundsException: String index out of range: 8] in class com.sap.aii.mappingtool.flib3.TextFunctions method substring[, com.sap.aii.mappingtool.tf3.rt.Context@107c499] com.sap.aii.mappingtool.tf3.MessageMappingException: Runtime exception during processing target field mapping /ORDERS05/IDOC/E1EDK02/DATUM.

sunilHi,
Do as follows.
Use standard date transformation function.In that format of source date give as hh:mm:ss ddMMyyyy and format of targeet date as you wish..It wil solve.
Please award marks if found useful.

Design of Cube for Year and Period from Posting Date
Experts,
In my report requirement one of the selection criteria is Year and Month (YY-MM) which needs to be got from the Posting Date.
In my ODS I have a 0PSTING_DATE. What infobjects are needed in the cube to get the value of YY and Period and the mapping from the 0PSTING_DATE to these infoobjects.
Thanks,

FLOAT TO TIME STAMP CONVERSION
Hi Folks,
I am getting some pain while i am converting from float values into timestamp...

microfortnights? (do the math!)
Anybody know where microfortnight originated?I once consulted in a British railway firm - they still used "chains" as a form of measurement.
http://en.wikipedia.org/wiki/Chain_unit
I thought I'd dropped back into the Middle Ages - and it wasn't the only way.
A HUGE* system.
The only thing any table had (apart from data) was a primary key. No DRI. No nothing. I ran
a query to look for foreign keys (way to start to understand the system) and got no results returned.
I thought the mistake was mine, but no - the developers proudly* said that the system only
had PK's and nothing else. I actually got into an argument with a semi-colleague/programmer who
thought that it was up to programmers to control referential integrity - I could only shake my head.
There was an issue with a CASCADE DELETE (it wasn't happening) - I advocated putting it in
the database, but was overruled because the system had to work with several RDBMS's.
Ah, well - Oracle Insights deja vu all over again!

Display custom time-stamps on a graph
Hello
I have some data in the format (yyyy-mm-dd, value). I would like to plot it like that in a graph chart.
The problem is that I cant transform the string 'yyyy-mm-dd' into a labview time-stamp.
Is there any way around?
Thanks,
AntonioUse Scan From String function:
Note that you did not provide time information, so you just get 6 PM. Check the LabVIEW Help for further details on the Scan From String function.

Problem with time stamp conversion
Hi All,
I am using the below code to convert timestamp to date and time , its working fine when i print it with write statement .
But i want to convert and pass the time and date with format to excel sheet , but its it taking again as string not in date time format .
please see the below code .
time_stamp = 20030309043000.
CONVERT TIME STAMP time_stamp TIME ZONE tz
INTO DATE dat TIME tim.
*WRITE: /(10) dat, (8) tim .
please suggest .Now that you've converted your time stamp to date (type d) and time (type t), convert them into alphnumeric fields like you want or tell excel what is in that column, since Excel isn't telepathic...and doesn't always know what we sent it....
data: date10(10) type c.
time8(8) type c.
write dat to date10 mm/dd/yyyy. "converts type d to user's specific date setting (not necessarily mm/dd/yyyy).
concatenate tim(2)
tim+2(2)
tim+4(2)
into time8 separated by ':'.
I do wish that I understood the fascination with Excel....when we have such marvelous tools to work with inside SAP or BW. -
Hi,
I need to convert the following time stamp into date and time. could any one help me how to do this?
Input format:

Convert statement wont work as it has characters in it.
At present i have converted by using split statment. is there any other way of doing it ?
Regards,
NiyazHi,
As in above post u use the FM to get your output. Check the below code:
data : a type string,
time_stamp type TZONREF-TSTAMPS,
date type SY-DATLO,
time type SY-TIMLO.
a = '2008-05-19T01:00:00Z'.
REPLACE ALL occurrences of '-' in a with space.
REPLACE ALL occurrences of ':' in a with space.
REPLACE ALL occurrences of 'T' in a with space.
REPLACE ALL occurrences of 'Z' in a with space.
time_stamp = a.
CALL FUNCTION 'ABI_TIMESTAMP_CONVERT_FROM'
EXPORTING
iv_timestamp = time_stamp
IMPORTING
O_DATE = date
O_TIME = time
EXCEPTIONS
CONVERSION_ERROR = 1
OTHERS = 2
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
write : date, time.

Return year, quarter, month and week from a date
I use this to convert a date filed to year_week, year_month, year_quarter and year.
But when I use it in views I got problem with queries, they take long time...
Is this the best way to do this?
Select to_char(rec_date, 'yyyy') || to_char(rec_date, 'IW') As year_week,
to_char(rec_date, 'yyyy') || to_char(rec_date, 'mm') As year_month,
to_char(rec_date, 'yyyy') || '0' || to_char(rec_date, 'q') As year_quarter,
to_char(rec_date, 'yyyy') As year
FROM tbltestI use this to convert a date filed to year_week, year_month, year_quarter and year.
But when I use it in views I got problem with queries, they take long time...
Is this the best way to do this?There is a big difference in showing a date in a certain format (year, month, quater, whatever) and restrict a selection to a certain date.
My guess is that you try to use the view with something like
SELECT * FROM myView
WHERE year = '2007' and year_month = '07'In this case the view is not able to transport the restriction (month='07') to the underlying column rec_date in your table tbltest.
The workaround is to directly use the date column and stay with a date value on it.
Like
SELECT * FROM myView
WHERE rec_date >= to_date('01072007','dd.mm.yyyy') and
and rec_date < to_date('01082007','dd.mm.yyyy') andA normal index on the column rec_date can be used in this second case. There is also a workaround for the first case useing function based indexes. -
I can't drag and drop from a data CD I recorded
I recently burned some audiobooks files (in mp3 format) as data cd's in Toast 8.0.1. When I go to reload them back onto my 20" 2 Ghz Dual Core Intel I can't drag and drop the files directly into any folder while using the columns view in a finder window. I can do it if I drag onto the music folder and let it spring open down to the level of the folder. I also can drag the mp3's into iTunes and then into the folder. This is not CD related since I used several diff brands.
I constantly update, backup, repair permissions, and do other maintenance so everything is up to date. I have noticed this behavior just since I started to use the program called Audiobook Builder. I am (and have always used) a non-admin user account. When this started a few months ago it seemed to go away with a restart, permission repair, or a logout but now it seems permanant. I checked user permissions on my home folder - I have not added any software since adding Audiobook Builder. Any idea's? I read something about trashing a com.apple pref but didn't try that.
I suspect Audiobook Builder since it changes the permissions and filetype to the iTunes Audiobook filetype but have not seen anyone reference this.

While the programming of course could be done, the idea of a function that performs on original unprocessed images seems to violate the whole idea of what Lightroom was designed to be. At least that's my opinion. Of course, the idea that Adobe should do this programming for a relatively small number of people (you're one of a very few people to ask for this, that I have read) seems to be something that isn't going to happen.
I agree, I can't see much reason for drag-and-drop to drag the unprocessed image - in other words, an image that isn't the one that you see when you drag and drop. I can see that just filling this forum with "why the heck does it do that????????" posts. I could be wrong, but I suspect that Adobe won't do that.
But if you do want to drag-and-drop the original unprocessed image, you can do it very easily now. Right click the image, choose "show in Explorer", and then drag-and-drop from Explorer. -
Importing tables and graphs from Word to pdf form
Hi. I've got a form set up in which people are supposed to submit a final report on a grant. There are large multi-line text fields in which they can enter text -- and most people are writing the text in Word and then just copying it into the text fields. In the process, however, they lose formatting of any tables, charts and graphs that are in the Word file. Is there any way to avoid that? Or is the only solution to ask them to append a Word-created pdf containing any tables, etc., to the form?
Thanks --OK, thanks.

I have a timestamp coming from flat file in the following format YYYY-MM-DD HH:MM:SS.mss(2007-02-21 11:48:31.000)
to store in Bw I have created a Object as data type :NUMC and length 14 ,I have conversion routine as times .I was wondering if this will work and also
can anyone suggest me to covert this as YYYYMMDD and tIme by spliting the field i am getting from flat file.
Thanks
SamuelHi Samuel,
You would need to write a routine for converting.
Char v_date(8), i_date(18), day(2), month(2), year(2).
i_date = trans_stru-<your date>.
day = i_date + 9(2).
month = i_date + 6(2).
year = i_date + 5(4).
concatenate year month day into v_date.
Result = v_date.
Bye
