Check on special characters

In my program, on the selection screen a user can enter any variable except special characters.How can I put a check on special characters??

hi,
In our key board, these many special characters present..
so try your code like this..
data: spe_char(31) value '~`!@#$%^&*()_+-=\|][{}";:,./?><'. ( include all
special chars whatever u want)
spe_char1 value ' '. ( this is to check empty space)
spechar2. (this is to check single ' ).
Create one text element and assign ' as value to that text element.
in ur program code as given below.
spechar2 = text-001.
if (fieldname) CA spe_char.
MESSAGE "special character is present in the given input
endif.
if ( fieldname) CA spe_char1.
message "special character is present in the given input
endif.
if (fieldname) CA spe_char2.
len = strlen( fieldname ).
if sy-fdpos NE len.
message "special character is present in the given input
endif.
endif.
Hope this code will guide you ..

Checking for Special Characters

I need to check if a textbox in my form containes special characters (entered by user). If there are any, I need to display an error message.
I have written a function but it's not working.
here's my function:
function checkForSpecialChracters(oFiled)
var userInput = oFiled.rawValue; // take the String entered by the user
var iChars = "@#$%^&*+=-[]\\\';,./{}|\":<>?~_";
for (var i = 0; i < userInput.length; i++)
if (iChars.indexOf(userInput.charAt(i)) != -1) {
xfa.host.messageBox("Please check for special characters. The following characters are not allowed: @#$%^&*+=-[]\\\';,./{}|\":<>?~_ ", "Error Message", 3);
// Change the color of the field
oFiled.fillColor = "255,100,50";
Any help would be greatly appreciated.
Thank you!

Paul,
It is working now. I don't know what I might have changed.
Here's my final function (It works!):
function checkForSpecialChracters(oFiled)
var userInput = oFiled.rawValue; // take the String entered by the user
var iChars = "@#$%^&*+=-[]\\\';,./{}|\":<>?~_";
var hasSpecialCharacter = false;
for (var i = 0; i < userInput.length; i++)
//app.alert("Value is: " + userInput.charAt(i));
if (iChars.indexOf(userInput.charAt(i)) != -1)
hasSpecialCharacter = true;
break;
} // end if
} // end For loop
if (hasSpecialCharacter)
// Change the color of the field
oFiled.fillColor = "255,100,50";
xfa.host.messageBox("Please check for special characters. \n\nThe following characters are not allowed:\n\n @#$%^&*+=-[]\\\';,./{}|\":<>?~_ ", "Error Message", 3);
else if (!hasSpecialCharacter)
oFiled.fillColor = "255,255,255";

Just a simple check with special characters

Hi guys and gals,
i created a boolean method that will check the value of string for any special characters like (/,'%&^# ), what i did is to used indexOf() method. it will return false if the string doesn't have any special character. But, i'm having a problem using the check for the backlslach character ' \ ', since it is considered as escape literal when i put inside indexOf('\'). i really need you help on this.
if you have other ways to check this kind of character, please put them here. i really need them bady. :D many thanks,

Look for "\\" or look up the unicode for "\" and use that.

How to check multiple special characters in this query.

When the master_title has no comma in it, I am getting an empty master_title. This is because INSTR(master_title,',',1,1) is returning 0.
In addition, I want to be able to specify other characters besides the comma. Example: ":" "/" "-".
Can we fit these options in the INSTR to look for them as well?
Query given below.
SELECT DISTINCT e.brm_id, SUBSTR(master_title,1,INSTR(master_title,',',1,1)-1) master_title
FROM e_m_view e
WHERE e.asset_dist LIKE'%WBPI Germany%'
OR e.asset_dist LIKE '%krupp%'
OR e.asset_dist IN (SELECT FN_SETRPTG(FN_GETPIREGN('%WBPI%')) FROM dual)
AND e.kl='Live' AND NVL(wbpi_publish_date,SYSDATE) <= SYSDATE
ORDER BY 2 ASC;

Special Characters Check in OBPM

Is this code good to check for special characters in OBPM 10GR3?
Pattern p = Pattern.compile("/[a-zA-Z0-9]/g");
     Matcher m = p.matcher("This is a string");
     boolean matched = m.matches();

Here's what I use to fix file names to ensure that they do not have special characters or international characters:

String afterConversion = "aAaAaAaAeEeEeEeEiIiIiIoOoOoOuUuUuUcC'n";
// does it contain international characters?
if (originalFileNameArg.match(regexp : '/[àÀâÂäÄáÁéÉèÈêÊëËìÌîÎïÏòÒôÔöÖùÙûÛüÜçÇ’ñ]+/').length() > 0) {
    int i = 0;
    String @char;
    while (i < beforeConversion.length()) {
        originalFileNameArg = originalFileNameArg.replace(from : beforeConversion.charAt(position : i),

0CUSTOMER Special Characters Error in Load

Hi Experts,
I am loading Customer Master data from R/3 into BW via 0CUSTOMER_ATTR extractor. Some user-entered fields in R/3 such as NAME, NAME1, STREET etc have some special characters - which look like a square.
This data used to come over into BW w/o errors. Now I have added some date fields to the extract eg CREATED_ON. All records that have the special characters now show-up incorrectly; as in ALL fields after the special characters have shifted to the left. So a few characters from CREATED_BY have spilled into CREATED_ON, Telephone Ext has spilled into Telephone Num and so on.
This is how the data is coming into the PSA from R/3. So I can't even check for special characters in the trans routine. ( The data is already bad in the PSA).I checked RSA3. there is no such spillage on the R/3 side. The spilling of data is happening between R/3 and BW.
Any Idea whats going on here and how to fix this?
thanks,
Kartik.

I think you have to check infoobject length in BI and the order of the infoobjects in the infosource compared to extractor fields.Any incosistency here may cause the spillage of data.
The new fields created in R/3 especially with varying lengths of data seems to be causing the trouble..

Already asked, and answered, here: http://forum.java.sun.com/thread.jspa?threadID=727919
See reply 4 in that thread, and scsi-boy's suggestion of writing another
method to check for "special" characters. And the links to the String
and Character API documentation given.

Error of Special Characters in Export to Excel

Hi,
I guess the error you are getting is a Parser error. To solve this problem, before putting the data on the XML file, you have to pass the data through an encoding process. For UTF-8 the code for encoding should be something like.
public java.lang.String encodeSpecialChar( java.lang.String attributeValue )
    //@@begin encodeSpecialChar()
          //Created By : AVIK SANYAL Date : 28 March 2008.
          //          Check for special characters like "&" in the String.
          //      replace "&" with "&"
          //      Returns the new encoded String.
          try {
               if (attributeValue != null) {
                    attributeValue = attributeValue.replaceAll("&", "&");
                    attributeValue = attributeValue.replaceAll("<", ""<"");// this is & lt
                    attributeValue = attributeValue.replaceAll(">", "">"");//this is & gt
               } else {
          } catch (Exception ex) {
               //          wdComponentAPI.getMessageManager().reportException(
               //               "Failed to convert the character.",
               //               true);
          //Returns the encoded String.
          return attributeValue;
    //@@end
Try this and let me know if this works. The reason is that in Binary Cache method, the data is passed in an XML format and the MS-Excel application reads this to show it in the spreadsheet. The characters '&', '<' and '>' can cause failure in reading from this file.
Thank You
Avik

OK....!!!!!
just download the Excel file (*.xls) and try open with Word-MS. In the document search by the string that you have mentioned in the question. (Use Ctrl +F).
If you see something like "ABC bla bla ba & instead of &amp , then you have to pass the data through the code I've mentioned.
You can get more details on encoding special characters UTF-8 in Google.com or Sun Websites etc.
You can also encode the & in hexadecimal format to get the desired output.

Check special characters in a string

Hi all
I am using oracle 10g.......
Need to know what should be the query to check whether a special character exists or not in a column value....used the following query like.....
select count(*) into emp_no_count_special_char
from dual
where REGEXP_LIKE(insert_data_rec.emp_no , '[#!$^&*%./\|]$' )
or REGEXP_LIKE(insert_data_rec.emp_no , '^[#!$^&*%./\|]' );
This works fine in case a string starts or ends with a special character ,what if a string of special characters lies in between numeric digits.
e.g: '100#$%7'
Please help find a query that checks for the existence of sp. characters irrespective of their position in the column!!!
Thanks
Dave

Hi Dave,
example below:
-- Check that at least one special character exists in the string
SELECT COUNT (*)
INTO emp_no_count_special_char
FROM DUAL
WHERE REGEXP_LIKE (insert_data_rec.emp_no, '[#!$^&*%./\|]');
-- Check that no special characters exist in the string
SELECT COUNT (*)
INTO emp_no_count_special_char
FROM DUAL
WHERE NOT REGEXP_LIKE (insert_data_rec.emp_no, '[#!$^&*%./\|]');
{code}

Regular expression: check for the presence of special characters.

I have the following requirement:
I need to check for the presence of the following characters in a keyword: @, #, > if any of these characters are present, then they need to be stripped off, before going further. Please let me know the regular expression to check for these characters.

I am trying to extend the same logic for the following characters:
.,?!@#%^&*()-~<>[]{}\+=`©® . here is the code fragment:
Pattern kValidator = Pattern.compile("[\\.,\\\\?!@#%^&*()-~<>[]{}\\+=\\`©®]");
Matcher kMatcher = kValidator.matcher(keyWord);
if (kMatcher.find(0)) {
keyWord = keyWord.replaceAll("[.,\\\\?!@#%^&*()-~<>[]{}\\+=\\`©®]", " ");
}I get the following error. This error is from the weblogic command window. I dont understand these special characters.
