How to take last 5 char from a string

Hi All
I have a requirement,
base on some comp i have to populate another field.
in this case i have compare last 3 char of a string
example if total string say asasdffrx i have to take last three char here it is frx.
always i have to last 3 char.
i can use +6(3) but it wont work every time because string lenght is not fix for all vaue.
thanks

Hi,
A.H.P sample is ok but insert additional check for strigs shorter than 3 (to avoid negative offset):
data : n TYPE I.
n = STRLEN( zfield ) - 3.
if n >= 0.
result = zfield+n(3).
else.
result = zfield.
endif.

How to remove last char in a string by space

I have to implement backspace application(remove a last char in a string , when we pressed a button).
for ex: I enter the no
1234
instead of 1236
So when i press a button on the JWindow... it should display
123
so that i can enter 6 now.
I tried to display the string "123 " instead over "1234" but it is not working when the no background is specified. but works fine when a background color is specified.
The string is displayed as
Graphics2D g = (Graphics2D)window.getGraphics();
AttributedString as = new AttributedString(string, map);
g.drawString(as.getIterator(),x,y);
In the map, the background is set to NO_BACKGROUND.
Thanks and regards

How to take the values from a String ( CSV   values).

Hi All,
I am passing csv String to a procedure as in parameter,but I have to take the values from a csv String one by one.Please let me know Is there any StringTokenizer function in oracle to take values like in java. Here is my javacode.
import java.util.StringTokenizer;
public class Sample {
     public static void main(String[] args) {
          String s="one,two,three,four,five";
          StringTokenizer stringTokenizer=new StringTokenizer(s,",");
          System.out.println( stringTokenizer.countTokens());
          System.out.println(stringTokenizer.hasMoreTokens());
          while(stringTokenizer.hasMoreTokens()){
                    System.out.print(stringTokenizer.nextToken());
o/p: one two three four five

Something based around one of these two methods should assist...
select substr( the_string
              , decode( level, 1, 1, instr(the_string,',',1,level-1)+1)
              , decode( instr(the_string,',',1,level), 0, length(the_string), instr(the_string,',',1,level) - decode( level, 1, 0, instr(the_string,',',1,level-1))-1)
              ) the_value
              from ( select '10,12,20,30,30,3,12,12,56' the_string
                     from dual
              connect by level < length(replace(translate(the_string,'01234567890','00000000000'),'0')) + 2
or
SQL> select REGEXP_SUBSTR ('a,b,c,d,e', '[^,]+', 1, level) from dual connect by level<=5

You could make your life a little easier and only use 1 format string. Use "%03b%02b%03b" for the format string. You can then expand the format string to allow multiple inputs. You will do the job of 4 functions with just 1.
"%3b" just says to give 3 spaces for the binary number. But any preceding 0s will be turned into spaces. Adding the 0 in there tells the format string to prepend 0s instead of using spaces.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Deleting last char in a string...

I have a string that is created as follows: strBuffer += k.getKeyChar();(k is KeyPressed ...KeyEvent) How can I delete the last Char in the string strBuffer?

Hi
// simply substring
if (strBuffer.length() > 1)
    strBuffer = strBuffer.substring(0, strBuffer.length()-1);
// you may also use
if (strBuffer.length() > 1)
    StringBuffer buffer = new StringBuffer(strBuffer).
                               deleteCharAt(strBuffer.length()-1);
    strBuffer = buffer.toString();
}I've not tested the above code myself & I've written the above code on the go after reading your query. The above code definitely work & help you.

How to create session id from different string controls

how to create session id from different string controls

fais,
Please create the VI you are talking about and save some default data into all of the controls. Also on the front panel, place the session ID that should be generated by that data. Now, post your VI to a response so I can download it. I can then take this VI and help you create the functionality. (Please post what version of LabVIEW you are using.)
My guess it that you are going to need to use a good number of string concatenations as well as a few string indexes to get parts of strings out. As for the date, you can use a Property node with the Numeric Text.Text property to get the actual string displayed on the front panel for the date and parse out the parts that you want.
