Counting the number of characters entered into a page item

Is there a way to count the number of characters that are entered into a page item. I've got a field that can contain up to 20 characters. If 20 are entered I can do a = on my search, if less than that, then I have to do a wildcard search. I currently do a substr on the field to see if position 21 is null and position 20 is not null, then I have a 20 character field. Is there a more efficient way to do this and also is there a way to actually show the character count as the page item is being populated

Hello user8014695 (name please),
Try coding the select for your search as
select ...
from some_table
where some_field like case when length(trim(:YOUR_ITEM)) = 20 then :YOUR_ITEM else :YOUR_ITEM || '%' end
Note - I included the trim() assuming blank characters before or after shouldn't count.
To show the character count as the item is being keyed-in, Google "javascript character count" for lots of ways to do this. To work these solutions into ApEx, check the ApEx help/documentation for incorporating JavaScript into your application - specifically the references on accessing page items using JavaScript.
Hope this helps,
John

How to count the number of characters

Dear All,
Can anyone tell me a Function Code or sample code to count the number of charactes in a text.
Regards,
Vijay

hi
<b>use the inbuilt function strlen</b>
Number of characters in arg; blanks at the end of data objects with a fixed length are not counted, although they are counted in type string data objects. If you use a non-Unicode double-byte code, a character that occupies 2 bytes is counted twice.
<b>example</b>
data: v_len type i,
v_str type string value 'gggugik'.
v_len = strlen( v_str ).
write:/ v_len.

How to check the number of digits entered into a itab-field.

Howdy,
I've got a program where i retrieve some data from the database and then I need to check if field BKPF-XBLNR has exactly 15 digits in it.
I've got no idea on how I would do this...
Can anyone help?
Thanking you kindly!

XBLNR is a character field. If you want to make sure all 15 positions have a digit and not some other character then use:
IF BKPF-XBLNR CO '0123456789'.
* OKAY, all 15 positions have digits
ELSE.
* NOT OKAY, at least one of the 15 is not a digit
ENDIF.
If you do not care what the characters are, then Rich has given you the solution but be aware that you could have embedded blanks, for example:
'ABCDEF GHIJK'
is length 15.

Thanks in advance !!

use a threaded application that is independent from your web app that will update your database every 15 minutes.. once a user has logged, the login time will be save on your db, thus it will be the reference time for your threaded application.. also put a tag on your db if the user has logged, the session has expired and if the user is his/her turn.. that is some idea that i can give you..

Workflow to count the number of items in a list

Hello Friends,
I've a requirement, I need to count the number documents uploaded for a particular list item (identified by a unique Title) and if the count matches with the count stored in another list for that particular list item, bingo......I will update the status
field to completed.
Can anybody please help me with this. How do I do this ? Is it possible even ?
Thank you very much in advance. :)

Hi,
I haven't tried this but i think you can achieve it by
1. Add an Call HTTP activity in your workflow and make a REST call get items
2. Use Count Items in (Dictionary variable)to get the Items counts of attachment.
3. Then, lookup for your another list in match item count.
Your REST query can be similar to this
url: http://site url/_api/web/lists/getbytitle('list title')/items(item id)/AttachmentFiles/To make Rest call in SharePoint designer https://sergeluca.wordpress.com/2013/04/09/calling-the-sharepoint-2013-rest-api-from-a-sharepoint-designer-workflow/

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,
    0x75, 0x72, 0x20, 0x6f, 0x77, 0x6e, 0x20, 0x66, 0x61, 0x72, 0x6b, 0x69,
    0x6e, 0x27, 0x20, 0x68, 0x6f, 0x6d, 0x65, 0x77, 0x6f, 0x72, 0x6b, 0x21

Thank you t quinn for your reply as I do really appreciate the help.
I don't quite understand what your suggestion was and before I try to figure it out and play around with numbers, I thought I should clarify further. When i wrote I want to paste the content into the cell and have it limited to 100 characters I was mis-spoken. I actually have all the content already in the columns in a spreadsheet and would now like to just limit some of the columns to hold only 100 characters in a cell so that when its a CSV file it will be accepted to the program I'm trying to upload it to.
SO does that change the way you can answer my question?
Is there a way to just limit the content currently in a spreadsheet to 100 characters per cell?
Kindly

How count the number of substrings in a string

Hi all,
I wonder if someone can help me and point out where I'm going wrong.
I want to count the number of substring starting with 'd' and ending with 'e' in a string supplied by a user.
currently my code is only counting the number of 'd' and 'e' characters in the string.
    public static void main (String [] args)
         Scanner input = new Scanner (System.in);
         String mstring;// string variable that the user will enter
         int i = 0; // upstep variable
         int count = 0; // int variable to count the number of substrings
         System.out.print("Enter a string: ");
         mstring = input.nextLine();
         while (i != mstring.length())
                   if(mstring.charAt(i)=='d'){count++;}
                   else if (mstring.charAt(i)=='e'){count++;}
                   i++;
         System.out.println("The total d e substrings is " + count);
}For example if the user enters adbedeaadffe the total number of substrings should be 5 but I'm getting 6 as the program is just counting the number of times it comes across 'd' and 'e'
Can anyone shed some light on this for me thanks.

Hi all I had a good few replies to this question but they seem to have been removed from the system for some reason.
I've changed my code slightly and it works but only for one round of the guard.
               Scanner input = new Scanner (System.in)
         String mstring;// main string variable that the user will enter
         int i = 0; // upstep variable
         int count = 0; // int variable to count the number of substrings
     System.out.print("Enter a string: ");
         mstring = input.nextLine();
         int y =mstring.length();
         while (i != mstring.length() && y !=0)
         if (mstring.charAt(i) == 'd' && mstring.charAt(y-1)=='e'){count = count+1;}
         y--;
         i++;
         System.out.println("The total a b substrings is " + (count));The above code will only print out one substring of adbedeaadffe but that is not what I need, I need to be able to print out all of the substrings.
Can anyone tell me where I'm going wrong.
Thanks in advance

Hi Venkat,
To check the number of digits, just convert it to a string and use the length() method. to get the number of characters. However, I am not getting your second point of printing the number?

Count the number of unique values in column

Hi
I have a large numbers file (thousands of rows) with data for different dates. I need to calculate the number of unique (distinct) dates are in the spreadsheet.
Does anyone know how to do this?
Thanks,
Bruce

bpj,
Let's say your date is in column B for this example and your first data row is Row 2. In another column you can enter into row 2: =IF(COUNTIF($B$2:B2, B)=1, 1, "") Summing the new column content will yield the number if unique dates.
As badunit observes, this will result in sluggish document. If the number of possible dates is small compared to the number of rows of data, it would be better to make a table of possible dates and count the number of occurrences of each of those dates in the data, a COUNTIF function on the frequency data for the date range will give you the number of unique dates, possible much more efficiently.

Count the number of mail views

Hi All,
I send an email which has following html code :
<pre >
<div xmlns="http://www.w3.org/1999/xhtml" class="blank-region">
<b> <img width="100" height="100" src="
https://xyz.com/pls/apex/Test.WCE_KM.download_my_files?p_id=22539227238556772"/>
</b>
This is the email text 1 <b> 1</b> times.
This is the email text 2 <b>0</b> people.
<div class="clear"/>
</div>
</pre>
The code is inserted into outlook or thunderbird as a mail text .
I would like to know how many people have opened that email. The idea is count the number of times the image is loaded in the mail box. and in the "download_my_files" procedure I write an insert statement to insert one count each time the image is loaded.
Since it is inserted as a html text, I am not able to capture the image download hits or how many times people have opened the mail.
Any idea how to achieve this ?
Regards,
Archana

Thanks AndyH for the reply. I am using "download_my_files" just to record the number of accesses for the files for later processing on the database server.
The mail body has few images which are stored in the table as a blob type. Those images are uploaded from the file browse button in the apex application.
I use "download_my_files" to record the number of accesses for the image files. Who views those image files in their mail when they open the mail- download_my_files process should be executed to show the file in the mail and ideally it should enter a hit in my hits table.
I use the following process to view a file in the browser as well in the mail body . I pass the file id as a parameter
CREATE OR REPLACE PROCEDURE download_my_files(p_file in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, BLOB_CONTENT, name,DBMS_LOB.GETLENGTH(blob_content)
INTO v_mime,lob_loc,v_file_name,v_length
FROM oehr_file_subject
WHERE id = p_file;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || v_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
INSERT INTO mail_hits(hitcount,viewdate) VALUES (1,SYSDATE);
end download_my_files;
But when I add the html code as a text which includes image file links and some text, as I mentioned in my first post-- it is pasted as a content on the mail body. It doesn't contain the link to the file in the apex server.
Is there any solution to track the hits in this method or You suggest any other method to calculate the mail count who has opened the email which has few images.
Regards,
Archana
