How to get the number of files currently open?

hi,
does any one know how to get the number of files currently open in windows OS?
e.g. lets say .txt files...
any comment will be really appreciated.
thanks

Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

[Win VC++ 6.0 ]How to get the number of files count in a folder using VC++ 6.0?

Hi all,
Can any one tell how to get the number of files(.EPS) count inside a folder when the folder path is specified in VC++ 6.0?
Thanks in Advance.

I'm a little confused by the question, but it sounds like you're asking how to count the number of files with a particular extension in a given directory? That's not really an AI SDK question, but it's a fairly easy one to find if you google it. If you're trying to use Illustrator to do it, AI doesn't have a general purpose file API. It has a few functions to do some things that Illustrator needs, but I don't think enumerating directories is one of them.

How to increase the number of files picked up by File adaptor

Dear all,
Can any one tell me how to increase the number of files picked up by File adapter.
Pl post ASAP.
Useful answers will be appreciated accordingly.
Thanks,
Srinivas

Hi Srinivasa,
there is no parameter for number of files to be picked..............if you have too many source files and you want to get them processed quickly, then you can specify a very small polling interval, then XI will pick your source files quickly..........but it will cause heavy load on the XI system which can lead to blockage of messages in queues........

How to get the number of columns in a result set???

hi everyone..
i am trying to establish a servlet applet communication....
my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
so is there a way to get the number of columns in a result set...???
and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
thanx in advance

You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

How to get the number of elements in DB

Could you tell me how to get the number of elements in DB??
My code to get the number is below, but I think it is not efficient
DB->cursor(DB, NULL, &cursorp, 0);
while ((ret = cursorp->c_get(cursorp, &key, &data, DB_NEXT)) == 0)
count++;
--------------------------------------------------------------------------------------------------------------

Hi,
The most efficient way to get a count from the database is using the DB->stat API (http://docs.oracle.com/cd/E17076_02/html/api_reference/C/dbstat.html)
The code will be something like:
        DB *dbp;
        DB_BTREE_STAT *statp;
        int ret;
        /* Print out the number of records in the database. */
        if ((ret = dbp->stat(dbp, NULL, &statp, 0)) != 0) {
                dbp->err(dbp, ret, "DB->stat");
                goto err1;
        printf("%s: database contains %lu records\n",
            progname, (u_long)statp->bt_ndata);
        free(statp);The code comes from the example included in the distribution at examples/c/ex_btrec.c
If the database isn't a btree, you should update to the appropriate statistics structure and field.
It's worth noting that retrieving the count is never a "cheap" operation. The count is not stored in the database - since doing so introduced a single point of contention that creates a bottle neck.

How to get the number of messages consumed by a MDB ??

Hi all,
How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
DMS ??? what use DMS ???
tanks

ok.
Well using DMS is one way to get at these sorts of stats in a programmatic manner.
There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
Which produces a table of the TEXT form:
<DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>
<statistics>
/oc4j [type=n/a]
/oc4j/default [type=oc4j_ear]
/oc4j/default/EJBs [type=oc4j_ejb]
/oc4j/default/EJBs/jmsrouter_ejb [type=oc4j_ejb_pkg]
/oc4j/default/EJBs/jmsrouter_ejb/AdminMgrBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 1 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 1 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/EnqueuerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/TimerHandlerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
</statistics>
</DMSDUMP>
Or produces an XML document of the form:
http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
You can use the Spy console to find the table that contains the details for MDB and then take it from there.
This is not what you specifically want to do, but it does provide a good overview of how DMS is used.

How to get the number of bytes at TCP port

Hi all,
How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

Hi
In LabVIEW you don't have the same property as in serail port.
You havn't "Byte at TCPIP port".
if you developp a protocol, one soltion, is to send the size to read.

How to get the number of current active external modes?

hi all,
I need to get the number of currently active external modes. This can be done by calling function THUSRINFO. But this only works propperly, if you are logged on only once. If you are logged on more than one time then the function returns several entries in the parameter USR_TABLE. The entries mainly differ in the first parameter TID (type UTID, INT4) "terminal-identification" but how can I know which is the valid one for my current session. Functions TERMINAL_ID_GET, SPH_TERMINAL_IDENTIFY and SPH_TERMINAL_ID_GET dont work.
Or is there another way to get the number of active external sessions?
Thanks in advance,
Michael

Hi,
tables: usr02, usr41.
data: OPCODE_MODE_COUNT(1) TYPE X VALUE 3,
      modes like sy-index,
      u_MODES LIKE MODES.
select * from usr02.
select * from usr41 where BNAME = usr02-bname.
    CALL 'ThUsrInfo' ID 'OPCODE' FIELD OPCODE_MODE_COUNT
      ID 'TID' FIELD usr41-TERMID
      ID 'MODES' FIELD MODES.
    IF SY-SUBRC = 0.
      u_MODES = u_MODES + MODES.
    ENDIF.
endselect.
if sy-subrc = 0.
    write:/ usr02-bname, u_MODES.

clear u_modes.

How to get the number of rows written to the header of the spool file.

Hi
I need to create a header line for the spool file .
the header line should include fixed length values .
The header should include the number of records found in the table with a maximum begin date (begin_date is the column of the table)
To get the header in the spool file , i wrote a select query has :-
--SPOOL 'C:\Documents and Settings\abc\Desktop\output.TXT'
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school
group by sysdate;
SPOOL OFF
which gets me all the rows in the table , but i only want the rows with the latest school_begin_date .
how can i achieve that ...
I know that a subquery should be written in the from clause to get the number of rows found with a maximum school_begin_date.
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school where
select rownum from dad.school
where school_begin_date = max(school_begin_date) ;
the error i get is
ORA-00934: group function is not allowed here
I NEED HELP ..IN GETTING THE ROWNUM JUST FOR THE LATEST BEGIN_DATE ?
PLS HELP ME IN WRITING THE QUERY .
THANKS IN ADVANCE .

Try this:
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000')||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) || rpad(' ',76,' ')
from dad.school
where school_begin_date = (select max(school_begin_date)
from dad.school);
