Number of characters in a string

Hi,
I need to find the number of characters in a string. For instance, i have a string type variable with the value "ABAP". How can i know how many letters "A" there are in that string? Is there any FM that does this?
Cheers,
Roberto

Hi,
you can make use of string operation FIND as:
DATA: text1 TYPE string VALUE `A`,
         text TYPE string,
      off TYPE i,
      moff TYPE i,
      mlen TYPE i.
off = 0.
WHILE sy-subrc = 0.
FIND text1 IN SECTION OFFSET off OF
       `ABAP`
       MATCH OFFSET moff
       MATCH LENGTH mlen.
IF sy-subrc = 0.
    WRITE / moff.
    off = moff + mlen.
ENDIF.
ENDWHILE.

Method to count number of characters in a string?

hi.
i'm trying to write some script that will count the number of characters in a string passed into a constructor and then compare it against another value to check whether the string passed in is valid.
something like this
public class Stringcheck
public static int maxStringLength;
public static double minSize;
public static boolean testStringLength(String x)
// Insert method for counting number of chars in String x and name as 'int numberOfChars
if(number of Chars <= maxStringLength )
return true;
else
return false;
can someone help me with writing this script.
Thanks
Richard.

ummm, you dont need anything fancy. try:
String test = "this is the test string";
int length = test.length();

Thanks!

can you also tell me how Browser handle the memory aspect? AFAIK, they don't.
All I need is a maximum of 1MB for one temporary single String.1MB should be small enough to fit in the memory... where do you get that string?

Return selected number of characters from a string

How do you select a certain number of charaters from a string?
For example:
I have a string that contains 51-108
I want to separate the string into two strings one containing 51 and another one containing 108.

A StringTokenizer will do it.
StringTokenizer strtok = new StringTokenizer(yourString, "-");

Count number of characters in a string

Another one for you experts:
Is there a way to count the number of "-" in the strings below:
For instance:

Any ideas?
Thanks in advance,

How to count number of characters in a string?

Hi
I need to display values in a script. but the alignment getting distrubed if it is less than 20 charaters, for exmple material descirption is only displaying 20 characters in script. if it is less than 20 charcters the alignment getting changed.
please help me ...urgent..
thanks in advance...

solution to this problem in script is not to count the characters but to align them based on positions .
1.
Use the tab positions for that paragraph format to display the values in a finite format .
In this u need to give the position start and position end length and use the same in the script as
p ,,&itab-f1&
say my value has to print from position 125mm to 155 mm
i take one tab position for this paragraph format P and maintain the same in the output.
here ,, is the tab position .
See whether it is one character or 20 character it has to behave the same way it should not be misaligned .
check the tab position for that paragraph format in Tabs ..

vijay.

Maximum number of characters for a BPEL string variable

Hi,
What is the maximum numbers of characters that a string variable in BPEL process can hold??.
Is there any document which describes the datatypes in BPEL.
Regards
V Kumar

Trick question - with or without the use of the FM GUI?
1. Via the FM interface to define a variable, FM will only save the first 1022 characters of your variable definition - if you dare try to enter that many via the GUI dialogue slot.
2. Importing a variable via MIF, adds virtually any length - I've tested out 2510 characters. HOWEVER, FM will only display the first 1023 characters of this string.
If you save the file to MIF, you can still see the original length of the variable. The other caveat is that if you touch any of these long variables via the FM GUI (Edit Variables), then FM will truncate it down to 1022 characters - regardless of how you save (binary or MIF).
FWIW - Klaus Daube lists (see: http://daube.ch/docu/fmaker25.html ):
Until FM 7.2: up to 255 characters including meta-notations (such as <Default ¶ Font> or \t - this counts as 16 resp. 2 characters). See also note Variables below
From FM 8.0: up to 2023 Windows Codepage characters or up to 2022 UTF-8 characters
I'd say that this is not quite correct. You could enter more than 255 prior to FM 7.2 as well, but again the display issue via the GUI kicked in and truncated down to 255. The newer versions only display 1022/1023 but you can enter more than 2510 characters (which in this case is futile anyway).

How do I limit number of characters in a JTextField?(different from others)

Hi,
I know this question has been posted several times on this forum, but my question is actually a different one. So please read.
I have the following code that puts two JTextFields in a JFrame. I want to limit the number of characters in the first JTextField to three characters. What's different about my question from other solutions provided, is that I don't want to be able to type more than three characters in the JTextField, and then not be able to get out of JTextField unless I have three or less characters. What I do want, is to have maximum of three characters, not be able to type the fourth, and have access to the other JTextField at all times.
I have tried the following solution of setting an InputVerifier to my JTextField, but it hasn't worked, since I can still type the fourth character.
Looking forward to your help!
Thanks.

Thanks, JayDS! Your suggestion worked. And I've come up with the following code with help of your suggestion. However, I'm not happy with the fact that I see empty spaces in my JFormattedTextField when I don't have anything entered in it, or when my textfield has focus and I click it again. Also, I'd like the text alignment to always stay on the right, even if I have less than 3 digits.
Could you please help me out with that?
Thanks!

Coding - returning the number of characters in a text box.

I am in the process of creating a cell phone simulation/animation in Edge Animate CC for use in a Captivate course. Basically, when a user clicks on number buttons on the virtual keypad, it displays the numbers in a text box , just like an actual cell phone would display the phone number on the screen as a caller is dialing. So, the user would click seven buttons and a seven-digit phone number appears on the virtual phone screen. This part of my animation works great and all seven digits appear, but I would like to modify the code so that a hyphen appears after the third button clicked. This way, the output better resembles an actual phone number instead of just a string of seven digits.
Here is an example of the code I currently have assigned to the #2 button on the virtual keypad:
var text = sym.$("PhoneNum").html();
text = text + 2;
sym.$("PhoneNum").html(text);
PhoneNum is the name of my text box on the stage where the digits appear as each keypad button is clicked.
In order to incorporate the hyphen after the third button clicked, I need to somehow return the current number of characters in the PhoneNum text box, then create an if/else scenario that applies the hyphen after the third button clicked.
Does anyone know how I can use either JavaScript or jQuery to return the number of characters currently in the PhoneNum text box?

No problem!
Basically the thing to remember is that unless you are needing to pass html to the object, you can use text() instead. text() also gives you the raw text without any html formatting (so you can assume what .html() would return)

What is the maximum number of characters in an Oracle 10G Instance Name

All,
Can I know what is the maximum number of characters in an oracle 10g instance name under AIX? Is it 7 characters or 8 characters?

One should really make the difference between db_name and instance_name: if instance_name default value is db_name it can be different
(even on a non RAC database).
For example with Oracle 10.2.0.4 you can create a database named DB78 with instance_name=DB12345678:
$ uname -a

Unable to read more than 255 characters in a string data type.

Hello,
I am using Crystal Reports version 11.5.8.826 to generate reports from databases such as MS-Excel & BaaN.
In Excel, there are records which carry string lengths of more than 255 characters. All though the fields are getting displayed in the report, the data being displayed gets truncated once it reaches a length of 255 characters.
Kindly provide me with a solution this problem.
Regards

Hello Manish,
I know that older versions of Crystal (Crystal 10 and older ) had a limitation of only 256 Characters for a string value. You should be able to use this code to get what you need.
We were successfully able to print out the Declaration of Independence through a Crystal report using something very similiar to this.

I like this version better because the array is completely dynamic. It can be as big or as small as it needs to be. There is always room for optimizations. But hopefully this will get you started on the right path.
