Count the number of extracted lines

Access vekp with vekp-objkey = mkpf-xblnr and vekp-vpobj = '03' and vekp-uevel = blank.
Get field vekp-venum.
Access again vekp with vekp-vpobjkey = mkpf-xblnr and vekp-uevel = vekp-venum.
Count the number of extracted lines.

Hi,
First u should start writing the code on ur own:
here's some sketch:
tables: vekp, mkpf.
data: begin of itab_vekp occurs 0,
      venum like vekp-venum,
     end of itab_vekp.
data: begin of itab_mkpf occurs 0,
        xblnr like mkpf-xblnr,
      end of itab_mkpf.
data: count type i.
select-options: s_xblnr for mkpf-xblnr.
select xblnr from mkpf into table itab_mkpf where xblnr in s_xblnr.
select venum from vekp
into table itab_vekp
* for all entries in itab_mkpf
where vpobjkey = itab_mkpf-xblnr
   and vpobj = '03'
   and uevel = ' '.
if sy-subrc eq 0.
count = sy-dbcnt.
endif.

How to Count the number of TAB chars value '0A' in a line?

I have a requirement to count the number of TABs in a text file that I am processing (they must equal 75) to ensure that all the fields have been submitted on the file I am reading?
How do I identify the TABs in a line?
I have this so far:
         CONCATENATE gv_unix_file gv_lstfiles-name INTO gv_unix_file.
          OPEN DATASET gv_unix_file for INPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          CONCATENATE gv_unix_file_arc gv_lstfiles-name INTO gv_unix_file_arc.
          OPEN DATASET gv_unix_file_arc FOR OUTPUT IN TEXT MODE ENCODING NON-UNICODE.
          IF sy-subrc <> 0 .
            message e000(zz) with 'Cannot access in_uk files'.
          ENDIF.
          DO.
            READ DATASET gv_unix_file into lv_str.
            IF sy-subrc <> 0.
              exit. "exit do loop, file is done.
            else.
              TRANSFER lv_str to gv_unix_file_arc.
            ENDIF.
          ENDDO.

Here is a sample code:
DATA: lv_string TYPE string,
      lv_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab,
      lv_i TYPE i.
DATA: result_tab TYPE match_result_tab.
DO 3 TIMES.
CONCATENATE 'A' lv_string INTO lv_string SEPARATED BY lv_tab.
ENDDO.
" this is how you need to find how many tabs are in your transfer work area...
FIND ALL OCCURRENCES OF lv_tab IN lv_string RESULTS result_tab.
DESCRIBE TABLE result_tab LINES lv_i.
WRITE:'No. of tabs found:', lv_i.

Count the number of lines in a txt file

I need to count the number of lines in a txt file, but I can't do it using readLine(). This is because the txt file is double spaced. readLine() returns null even if it is not the end of the file. thanks for the help

I need to count the number of lines in a txt file,
but I can't do it using readLine(). Then just compare each single byte or char to the newline (code 10).
This is because the txt file is double spaced. readLine() returns
null even if it is not the end of the file.Errm what? What do you mean by "double spaced"? Method readLine() should only return null if there's nothing more to read.

Count the number of lines in each file in a directory

Hello,
I would like to count the number of lines for each file in my directory and subdirectories.
I wonder how can I count the lines of the specified files?
Here is the program which is listed the files in the specified directory:
                    String path = "C:/User/Studies/Pracices/src/Pract1";
       String files;
       File folder = new File(path);
       File[] listOfFiles = folder.listFiles();
       for (int i = 0; i < listOfFiles.length; i++)
        if (listOfFiles.isFile())
     files = listOfFiles[i].getName();
     System.out.println(files);

Ok so one more question.
Actually my path is pointing to one Directory and like here I can just read from one file that the name of the file should be specified in the path is it possible to help me in that part?
File f = new File("C:/User/Studies/Practices/src/Pract1/");
FileReader fr = new FileReader(f);
      BufferedReader br = new BufferedReader(fr);
      String str = br.readLine();
          LineNumberReader ln = new LineNumberReader(br);
          int count = 0;
          while (ln.readLine()!=null)
              count++;
          System.out.println("no. of lines in the file = " + count);

Counting the number of lines for each procedure in a package

Hi,
I would like to write a query on USER_SOURCE that can display the number of code lines for each procedure/function in a package.
Is it possible to write such a query? Maybe by using analytical functions?
for example in the following example i would like to count the lines between "PROCEDURE proc1 IS" and "END proc1;" and between "PROCEDURE proc2 IS" and "END proc2;"
SQL> select text from user_source where name='PKG_TEST' and type='PACKAGE BODY';
TEXT
PACKAGE BODY PKG_TEST IS
PROCEDURE proc1 IS
BEGIN
    update t1 set EDITION_NAME = 'AAAAAAA';
    commit;
END proc1;
PROCEDURE proc2 IS
BEGIN
   update t1 set EDITION_NAME = 'AAAAAAA';
    commit;
END proc2;
END PKG_TEST;thanks for helping

Java Program+To count the number of lines in a method excluding comments???

Hi friends
can u plz help me out, the java program is counting the number of lines in a method excluding comments.
The first thing is how to identify a method, then there can be an inner method inside the parent method,
Please friends its urgent
Bye
Sandy

There's no such thing as an inner method in Java. You can either write the code yourself to parse Java source, or maybe something like ANTLR can do it.

Help with how to count the number of tokens from the first line

I can print out the amount of tokens from each line,
But i only want the first line to be counted, And i
also do not want the delimeters to be counted.
could you please give me some ideas?
Thanks
try
   BufferedReader br = new BufferedReader(new FileReader("item.kr"));
   while((str=br.readLine())!= null)
      itemslist.add(str);
catch(IOException ioe)
   System.out.println("Exception Occurred!!!");
}This snippet gets one Line from the item.kr file.
Then i would count (By useing a diffrent String Tokenizer) to count only this line!!!

Help!! count the number of words in one line

the question is that use JOptionPane and Array to count the number of words and characters that user inputed.
for example, if I enter the " this is a java program"
that messages have display 5 and 18.
please show me the a completely program.
thx!!!!

You guys are heartless. Even you weren't born with programming knowledge hard-coded into your brain. Even you had to start from zero. Even you had to struggle at something in your life. In this spirit, I think that we should give this poor student a break and try to help him as much as possible. Here, try out my program, and perhaps it will give you some ideas for your own:
public class WordCountingHomework
public static void main(String[] args) throws InterruptedException
    String input = JOptionPane.showInputDialog("Please enter a String");
    // get your String and split the String into words
    // This will allow you to count words easily
    String[] strArray = new String(wordCountByteArray).split(" ");
    int delay = 400;
    for (;;)
      // loop through the array to count the words
      for (String string : strArray)
        System.out.print(string + " ");
        Thread.sleep(delay);
      System.out.println();
      delay *= 7;
      delay /= 10;
private static byte[] wordCountByteArray =
    0x50, 0x6c, 0x65, 0x61, 0x73, 0x65, 0x20, 0x64, 0x6f, 0x20, 0x79, 0x6f,

Count the number of occurences of a pattern in some files

Hi,
I am trying to extract some patterns in files using regex. I can easily extract the patterns using my program. I also wanted to count the number of occurences of the pattern in the files. For that I have written this code:
int count=0;
          while (m.find())
             System.out.println("Found Patterns: "+m.group());
             count++;
       System.out.println(count); //giving error saying identifier expectedUnfortunately I am getting an error saying identifier expected at the count line. What to do?
Thanks

Is there a way to count the number of times an array moves from positive to negative?

I have an array of values, and I need to find the number of times that the array changes signs (from positive to negative, or vice versa). In other words from a graphical standpoint, how many times a certain line crosses the x-axis. Counting the number of times the array equals zero does not help however, because the array does not always equal exactly zero when it crosses the axis (ie, the points could move from .1 to -.1).
Thanks for you help. Feel free to email me at [email protected] I only have lv 5.1.1 so if you attach any files, they cannot be version 6.0.

Attached is a VI showing the # of Pos and Neg numbers in an array, with 0 considered as non-Pos. It is easily modifiable to other parameters - including using the X-axis value as your compare point versus only Zero.
This is a modified VI from LV (Separate Array.vi)
Compare this with your other responses to find the best fit.

How do I count the number of occurrences of a string within a group of cells?

Hello all, I'm trying to figure out how to count the number of times a child has completed certain tasks. Here is a sample of the data (it is highly simplified here, but contains what I hope is needed to answer my question):
Unnamed Table
Objective
John
Ann
Alex
Dave
Eric
20a 20b 20c
x
20a 20b 20c
x
20a 20b 20c
x
x
19b 20a
      x
       x
20c 21b 22
     x
What I am trying to do is count the number of times each child completed each objective - but I can't figure out how to go about splicing up the "objectives" fields for counting while still being able to compare them to whether or not the "child" has 'an x in the box' in that particular row.

If I read your example correctly, John's counts should be 2 for 20a, 1 for 19b, 20b and 20c, and 0 for any other objectives listed.
Here's an example that will work for your data set, assuming that any objective ma occur only once in each row of column A of the Main table. I've added an a to objective 22, but I think it is unnecessary, provided there is no objective 122, 221, etc.
This uses a two step process.
The table AUX extracts the objectives completed by each student, using the checkboxes in Main. Note that it also adds a space at the beginning and end of each string. This provides an extra character before the first objective code and after the last objective code in that row, used by the wildcard specification in the formula in the Summary table.
Formula:
Aux::B2: =IF(OFFSET(Data :: $A$1,ROW()-1,COLUMN()-1)," "&OFFSET(Data :: $A$1,ROW()-1,0)&" ","")
Fill right to the last column and down to the last row of Aux.
Summary uses COUNTIF to count the number of occurrences of each of the objectives listed in column A of that table.
Formula:
Summary::B2: =COUNTIF(Aux :: B,"=*"&$A2&"*")
Fill right and down as the previous formula.

Count the number of Pluses Generated

we are using the pxi-6602(counter/IO) along with SCB-68.
the problem we are encountering is that,we want count the
number of pulses generated.
we are using the counter0 and generating the
pluse, using the example VI Genrate Finite pulse(TIO).VI
which we are able to capure at the CTR0-out.
we want to count the number of pulses generated at
CTR0, so we have connected to the gate of CTR1
and we are running the example vi Measure Pluse NI(TIO)
we are not able to count back the number of pulses generated.
can any one guide us ....
are we heading in the right
1)is it possiblt to count and measure the number of pulse generated.
2)is it neccessary to specify the PFI line in the measuring/counting.
3)output of one counter is connected to gate of the other counter to measure. is it right
4)since this is the first time we are using counter/timers, please guide us, about connecting the
out and source and gate in scb-68.

I'm not at a LV PC now, so I can't look at the examples you mentioned. However, the primary problem is that when you generate a finite pulse train on Ctr0, the DAQ driver makes use of Ctr1 to control the # of pulses generated by Ctr0.
Because you have a 6602, you can simply measure the # of pulses with any of the other 6 counters on board. Ctr1, the one you might naturally think to use, is the only one that won't work.
The method will depend on whether you're using traditional NI-DAQ or DAQmx. The example names sound like traditional NI-DAQ, so the simplest thing is to actually wire from Ctr0 output to your measurement Ctr's Source input. Each of the Ctr's has a different PFI pin as its (default) Source input. Summarizing your questions:
1. Yes it's possible to measure # of counts generated by Ctr0 with any Ctr EXCEPT Ctr1. (Note that if you generated continuous pulses with Ctr0, you could then use Ctr1 to count them).
2. It's possible to specify the PFI line for counting pulses. If you physically wire to the default Source input, it won't be necessary.
3. Output of one counter should be connected to the SOURCE of another counter.
4. Ctr0 Out should be wired to, say, Ctr2 Source. Don't have hw here to be able to identify pin #'s.
Final note: under DAQmx, you wouldn't need any wiring. You can programmatically tell any measuring counter to count the edges on any other pulse-generating counter.

A quick way to count the number of newlines '/n' in string of 200 chars

I am trying to establish the number of lines that a string will generate.
I can do this by counting the number of '/n' in the string. However my brute force method (shown below) is very slow.
Normally this would not be a problem on a 2800mhz Athlon (Standard) PC this takes < 1 second. However this code resides within a speed critical loop (not shown). The code shown below is a Achilles heal as far as the performance of this speed critical loop goes.
Can anyone suggest a faster way to count the number of �/n� (new lines) within a text string of around 50- 1000 chars, given that there may be 10 � 100 newline chars. Speed is a very important factor for this part of my program.
Thanks in advance
Andrew.
    int lineCount =0;
    String txt = this.getText();
    //loop throught text and count the carridge returns
    for (int i = 0; i < txt.length(); i++)
      char ch = txt.charAt(i);
      if (ch == '\n')
       lineCount ++;

Well, here is a C version. On my computer the Java version (reply 9 above) is slightly faster than C. YMMV. For stuff like this a compiler can be hard to beat even with assembler, as you need to do manual loop unrolling and method inlining which turn assembly into a maintenance nightmare.
