Calculate length of a string

Hello.
I have written a function to calculate the length of a string, it gives the wrong length can you help me fix the codes?
public int GetStringLength(String z)
int y = 1;
int x = 0;
while (1 > 0)
try
char m = z.charAt(y);
x = x + 1;
y = y + 1;
catch (Exception fini)
return x;
}

How to calculate length of the string in transformation file

Hello all
I have tried a number of ways and I am not able to calculate the length of the incoming field in transformation file for my data load. Here is the issue.
I have an incoming string of length 10 and I need to use it to update multiple dimensions which will need first 2, 4 ,6 , 8 characters respectively.
Now in transformation file ID=ID(1:2) works perfect. However, the BW InfoObject will have multiple values as shown below:
ID
Description
AB
Business
ABCD
Business Organization
ABCDEF
Business Line
ABCDEFGH
Product Family
ABCDEFGHIJ
Product Line
ABCDEFGHIJKL
Brand
I want to update my dimension for Business Organization. I need to update only the records where the length of the incoming string is 4. If I do ID(1:4), I will get the duplicate records and will see the ID less than 4 characters in rejected records. The latter is not such a big issue but the former one is as I need to fetch the right description as well. The formula should check the length and then only pass the record else a dummy value.
A formula to achieve this in the transformation file is what I am looking for.
Regards
Gajendra

Thanks Vadim for the quick response!
I am also trying something similar and really appreciate your input here. However, I am not sure if the conversion is really happening.
Here is what I have done:
But the strings <> 4 in length are still passing through.

How to calculate the length of a string

Hi everyone,
A simple question. How to calculate the length of a string?
Thanks!

Hi Wuyia Nata,
As everyone has suggested you search the forum before posting a question, i guess for basic questions u never have to post a question, you will get the answer in your search. Anyways see the code below for string lenght.
Data:
w_string type string,
w_lenght type i.
w_string = 'vhdskbvsdkbvdsvnsknvs'.
w_lenght = strlen( w_string ).
Write:
w_lenght.
With luck,
Pritam.

How is the length of a string calculated in Java? and JavaScript?

Hi all,
Do any of you know how the length of a string is being calculated in Java and JavaScript? For example, a regular char is just counted as 1 char, but sometimes other chars such as CR, LF, and CR LF are counted as two. I know there are differences in the way Java and JavaScript calculate the length of a string, but I can't find any sort of "rules" on those anywhere online.
Thanks,
Yim

What's Unicode 4 got to do with it? 1 characteris 1
character is 1 character.
strings now contain (and Java chars also) is
UTF-16 code units rather than Unicode characters
or
code points. Unicode characters outside the BMPare
encoded in Java as two or more code units. So it would seem that in some cases, a single
"character" on the screen, will require two charsto
represent it.So... you're saying that String.length() doesn't
account for that? That sux. I don't know. I'm just making infrerences (==WAGs) based on what DrClap said.
I assume it would return the number of chars in the array, rather than the number of symbols (glyphs?) this translates into. But I might have it bass ackwards.

I don't want it to change the size even if the length of the string exceeds the width of the comboBox
what should i do?

anyone with better solution?

How to find the total length of the string drawed in a rect?

Hello Everybody,
I am drawing a string in on one rect using drawInRect method. This drawInRect method gives us a return value as size of the rect. I need length of the string that is did draw in that rect, but didn't find any api to do this.
Can anyone tell me , how find the length of the string which we did draw in rect?
Any help regarding this issue , is highly appreciable.
Thanks,
Pandit

Hi Adreas,
First of all, very thanks for the response.
Actually , I am looking for other thing. Using drawInRect method I am drawing contentString in self.rect like below.
//code
[contentString drawInRect:self.rect withFont:[UIFont fontWithName:@"Verdana" size:14.0] lineBreakMode:UILineBreakModeWordWrap alignment:UITextAlignmentLeft];
//End
My contentString is much larger string, so I am not able to draw it in rect(length: 320.0 height: 460.0) completely. My rect is showing only a part of a contentString. So I need to get that part of string which did draw in the rect, so that I can process my contentString to get the remaining string to draw it a next rect.
The above code statement is returning me the CGSIZE , it is giving the size of the rect but not giving any information of the string which get draw in that rect.Do you have any idea how to do this?
Any information on this is highly appreciable.
Thanks,
Pandit

Length of a string without using any built-in functions

A string is internally represented by a character array. An array of characters will reside on the stack, not the heap. Yes, we always learned that String is a reference type, but what goes on in your memory might still surprise you...
A struct is internally represented by only it's private properties, sequentially on the stack.
So basically, what I thought is happening by messing with the structlayout: is only tricking our programming a bit into thinking that the top X bytes on the stack represent a chararray, while actually we put them there as a string.
Wrong. True. And wrong.
A string is internally represented by, in that order, an array length, a string length, the chars. None of them resides on the stack.
An array is internally represented by, in that order, an array length and the chars. None of them resides on the stack.
When you use the FieldOffset attribute to handle the string as a char array, you don't get anything right:
- the Length returned is the "array length" of the string, which is equal to the string length + 1.
- the chars returned by the array indexer are shifted by 2 chars (the length of the "string length" field).
You can use the FieldOffset to make that work, but it needs a little bit more work.

Length of the string passed to rwcgi60 in Oracle 6i

Hello,
I am running the report from the web. The url will be something like
http://localhost/cgi-bin/rwcgi60.exe?server=repserver+report=.rep+all the input parameters.
When the length of the string passed from report= execeeds certain limit(indicated by dashes) I am getting the cgi error
Error: The requested URL was not found, or cannot be served at this time.
Oracle Reports Server CGI - Unable to communicate with the Reports Server.
If I remove some of the select criteria then I could execute the report from the web.
Any body has any soln. for this.
Thanks in advance,
Vanishri.

The limit is very high and you should not be hitting this problem. There are couple of fixes done in this area. Please apply the latest patch (Patch 10) and try.
Other solution is you can have a mapped key in cgicmd.dat file and use the key alone in the URL. In the cgicmd.dat file, you have to map say
key1: REPORT=your_report.rdf USERID=user_name/password@mydb DESFORMAT=html
SERVER=repserver DESTYPE=cache
Please refer to the Publishing reports or Reports services manual at http://otn.oracle.com/docs/products/reports/content.html

PowerShell: Want to get the length of the string in output

Hi All,
I am typing this but it is not working. Does anyone know what I could be doing wrong.
The command I wrote is:
GCI -file | foreach {$_.name} | sort-object length | format-table name, length
But it is not working. I am expecting a name of the file and length of the string like 8 characters etc. my file is called mystery so it should have 7 as its output of the name, length.
Thank-you
SQL 75

Get-ChildItem supports both -File and -Directory.
Help will help:
https://technet.microsoft.com/library/hh847897(v=wps.630).aspx
Read the first couple of parameters to see.
GCI -file | sort-object length | format-table name, length | ft -auto
Seems to be a rasher of bad answers to day. YOu were just extracting the name property then trying to sort on a property that doesn't exist.
Do the sort first then select the properties.
it helps to test answers before posting. I know because I get bit by posting without thinking to often. I have to remember to think first.

Variable length declaration in string type

hi all
can anyone tell me how to declare length for string type of variables

Hi,
The length of a string is not static but variable and adjusts itself to the current field content at runtime. Dynamic memory management is used internally. Strings can have any length. The initial value of a string is an empty string with length 0.
Hope this will make you clear. Please reward if answer satisfy you !!!

use FM
SWA_STRINGLENGTH_GET
enter your string in EXPRESSION and use the others if needed use "X" for all three except EXPRESSION
EXPRESSION GFFHG
CONDENSE_NO_GAPS
CONDENSE
WITH_LEADING_BLANKS

Any method to find out length of a string !!

Hello friends,
 I used describe statement to find out the length of a string, but it actually returns the whole length of the string but not actual no. of char's in this.
any one suggest a solution for this.
Senthil

Hi Senthil
The ABAP function STRLEN returns the length of a string up to the last character that is not a space.
[COMPUTE] <n> = STRLEN( <c> ).
STRLEN processes any operand <c> as a character data type, regardless of its real type. There is no type conversion.
As with mathematical functions, the keyword COMPUTE is optional.
DATA: INT TYPE I,
WORD1(20) VALUE '12345'.
 WORD2(20).
 WORD3(20) VALUE ' 4 '.
INT = STRLEN( WORD1 ). WRITE INT.
INT = STRLEN( WORD2 ). WRITE / INT.
INT = STRLEN( WORD3 ). WRITE / INT.
The results are 5 , 0, and 4 respectively.

Determining length of a string

Hi,
I got a string e.g strx = "abcde". Is there any function to determine the length of the string, here e.g. it would be 5?
I appreciate any help in advance. Thanks.

Use the length() method of the String object class
String strx = "abcde";
int len = strx.length();
System.out.println(len);

Determining the actual length of a string based on pixels?

How would you determine the actual length of a string based on pixels? Reason for is because a length of a string containing all " l " chars would be a lot smaller then the length of a string containing all "H" chars based on pixel width.
thanks,
newbie

Yes, look at the FontMetrics class which has methods to do just that. To get a relevant FontMetrics object, try "x.getFontMetrics(f)" where x is a Component and f is the Font your string is represented in.
