how can i know the number of lines in field-symbol internal table

Hi,
If your field symbol has been defined as an internal table :
Use std describe as
Data: l type i.
describe <fs> lines l.
'l' will contain the number of lines as needed.
FYI
The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.

How can I know the number of ejb instances

Hi all,
We need to know how can we get the number of ejb instances (entity and session) while the application is running.
We have a memory leak, so we need to know the amount opf memory used.
Please, itÂ´s quite urgent, can anybody help us? It seems like an Oracle 9ias 903 bug.
Thanks

I'm not sure if this will help you, but the "Spy" application that comes with OC4J stand-alone may help. I suggest you search this forum's archives for the words "Spy" and "AggreSpy".
Good Luck,

How can I know the number of concurrent users

Dears,
We have a sizing document from one of our vendors which is asking for the "Peak number of concurrent users in E-mail".
How can we estimate that? is it something like 5% of Total # of Users?

How can I reduce the number of lines in live paint?

I'm trying to use adobe illustrator to color the background of a photograph green while keeping the person in the picture the same color.
I used live trace to get a vector image and then attemped to use live pain to finish the job, but I end up with thousands of blue lines and gaps that are too small to color in. Is there anyway i can reduce the number of gaps so that i can actually paint the background?
I've already tried the gap options and adjusting the settings to small medium or large did nothing.
If this isn't possible, is there any other feature in adobe illustrator that would allow me to achieve my goal?
I have a photograph with a person in the middle; i want the person to remain the same and the background to be changed to green.
Thanks for your time.

Would be easiest to fix this when tracing.
You could try the magic wand tool to select them (but you'll have to expand the live paint object)

How can I get the number of lines in a string?

I have a lone string with multiples lines (return). How can I find out how many lines in the string?

For the counting of no.of lines, try the Line Counter here http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000BB700000&USEARCHCONTEXT_CATEGORY_0=_49_%24_6_&USEARCHCONTEXT_CATEGORY_S=0&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0
As for extracting data without having worry over the description, you may wanna try using "Configuration File VI" in LabVIEW's File I/O function palletes.

How can I check the number of lines per inch in my document (I need no more than 6 per inch!!)

I need to produce a dopcument in New times Roman with a minimun of 12 ot font size, single spaced and , with no more than 6 lines of type per inch?
How can I check that I do not have more then 6 lines per inch?
thanks in adavance!!!

If this is about Pages for iOs, you can certainly set TNR adn 12 pts, but no, there is no lines per inch settings.
If this is about Pages for OS X, you are in the wrong forum.

How do you find the number of lines in a file?

I need to count how many lines there are in a file, I am using a BufferedReader to read in the data, but how can I find the number of lines?
Thanks

That depends. How do you define a line? Is it a specific number of
characters, a String that's terminated by a newline character or some
combination thereof?

How do I increase the number of lines presented in a drop down list?

When I am entering a single character/number for each of a random selection of three letters in a password verification, I get a drop down list from A to S only, the first 20. Accessing letter T to number 9 means scrolling down. How can I increase the number of lines in a drop down box to 36?

If you are taking about an interface on a website, this is up to the ui designer. But there is a reflow that depends on screensize for the Firefox UI.

Please advise...
Thanks

Hello,
Try this way:
If both the type of internal tables are same then you can directly assign dynamic internal table to static internal table.
itab = <itab>.
Suppose you have field symbol internal table <itab> which is different in structure from ITAB.
Now, you can create <wa> as follow:
FIELD-SYMBOLS <wa>.
DATA wa TYPE REF TO DATA.
CREATE DATA wa TYPE LINE OF <itab>.
ASSIGN wa->* to <wa>.
This way your work area is read.
Using [ASSIGN COMPONENT|http://help.sap.com/saphelp_nw04/helpdata/EN/fc/eb3923358411d1829f0000e829fbfe/content.htm] syntax you can read required component of <wa>.
Finally you can use that value to load static internal table.
You can also refer to my thread on [Dynamic table|Re: Creating Dynamic table].
Hope this helps!
Thanks,
Augustin.

How can I limit the number of emails retained on my ipad air?

How can I limit the number of emails that are retained on my iPad Air? Because of legal requirements of a long-term project, I cannot permanently delete emails relating to that project from my ISP's mail server. My gmail account contains over 17,000 emails and, upon setting up my new iPad, and updating to ios 7.1.1, I now have all 17,000+ emails taking up space. I would like to limit the emails by count as I was able to do on my old iPad running ios 5.1.1 OR to retain them based on date range. I have not found any instructions on the support discussions or general iPad blogs that allow me to do that. Any way around this problem?
I also miss the 5.1.1 mail search feature that allowed me to narrow the search by from/to/subject/all. Does anyone know if that feature is available using some little-known ios 7.1.1 feature?
Thanks for your help.

IOS 7.1.1 doesn't show a "days to sync" parameter anywhere in SETTINGS/Mail,Contacts,Calendars/ACCOUNTS/GMAIL Account/ GMAIL Acccount Info. There is nothing in iTunes relating to such an option either. So, it seems I'm back to square one.
If you have a decent mail provider like Microsoft Hotmail or Outlook.com mail it does.
If you have Gmail it does not. Quite right. Gmail is rubbish.
