Convert string to ASCII entities

Does anyone know if Java has a method to change 'a' into 'a', 'b' into 'b' and so on? Or at least change 'a' into the ASCII value '97'?
thanks.

Convert String from ASCII to ANSI

Hi,
a command line instruction via LabVIEW function "System Exec.vi" retrieves me a string in ASCII format. Is there a function to convert string from ASCII to ANSII format? I use LabVIEW 8.5 German Installation.
Kind Regards

Hallo Christian,
AFAIK there is no such in function in LabView...
But you can:
- use "Search and replace string" to search for ASCII chars and replace them by their corresponding ANSI char, do this in a loop for all chars to be replaced (acceptable speed for small strings...)
- convert the string to an U8 array and use a lookup table to convert all bytes from ASCII to ANSI, convert back to string (may be faster for long strings...)

I need a java function that convert string to ASCII,

I have a string like "test123"
I want to convert this string to ascii code?how could I do this

It is not compeltely clear, what you need, but String has this method:
public byte[] getBytes(String charsetName) throws UnsupportedEncodingException

Convert string to ascii

does anybody know how to convert a string to it's ascii code?

does anybody know how to convert a string to it's
ascii code?In Java characters are represented with Unicode,
http://unicode.org
Fortunately the commonly used Basic Latin Unicode character set corresponds to the ASCII character set. So to get the ASCII representation of a char you just interpret the char as a number.
char ch = 'A';
int i = ch;
System.out.println("Both Unicode Basic Latin and ASCII use " + i + " to represent an " + ch);

How can i convert values in my string to ascii characters

Hi guy.
I am wrinting a code but i m stuck, I have a string with (Battle of Midway) in it, Now i want to convert each character in this string with the asci character,,,
String temp = {"Battle of Midway"};
so the ascii will be:
B=66 a=97 t=116 l=108 e=101 o=111 f=102 M=77 i=105 d=100 w=119 y=121
i found all these number for all the charachers, but i donno how to covert this string into ascii characerts... ofcurse i can do it one by one...but is there any class or method i can use for this,,,,, Once i convert all the character (from string) to ascii character THEN i have to convert it back from ascii to character,,
Is anybody has any idea
Thanks alot in Advance

You get get the ascii code for those characters by doing something like:
int ascii = str.charAt(0); //Get ascii value for the first character.

How to convert character string into ascii format correctly

dear all
I'm using encryption technique in my application(oracle formas 6i). character stream convert to the ascii format and add some numeric value and again convert to the character format
>>>>
here I'm using ASCII and CHR functions.
>>>>
.net program also using same algorithm to encrypt this password.....finally both the character strings are not equel.(This happens if the character string's ascii value greater than 127. otherwise both are equel).
pls give me a solution for this
thanks and regards
buddhike

hir dear
do u want to encrypt & dcrypt your password.which version of oracle you are using
first store these procedure in Oracle Databases: dbms_obfuscation_toolkit, dbms_crypto, Transparent Data Encryption
now u can use these procedure to encrypt & dcrypt your password
if you any query about those procedures you can ask me

Convert char to ascii code and vice versa

HI
Is there any function module to convert char to ascii code and vice versa.
Thanks in advance

Hi,
be careful if you have unicode running in your system. URL_ASCII_CODE_GET is platform-dependent so it will return the internal HERX representation of the character in your system - which is hopefully and in most cases ASCII.
Under unicode, we use double-byte characters here. I tried this function and the result CHAR_CODE is '00' regardless what character I specify for TRANS_CHAR. But the coding is so simple I corrected resultig in this sample code:
[P]
convert p_form to ASCII (internal) representation
DATA:
    l_ofs TYPE syfdpos,
    l_len TYPE sy-linsz,
    l_ascii TYPE i.
FIELD-SYMBOLS:
    <x> TYPE x.
l_len = STRLEN( p_ascii ).
DO l_len TIMES.
    l_ofs = sy-index - 1.
    ASSIGN p_ascii+l_ofs(1) TO <x> CASTING.
    l_ascii = <x>.
    WRITE: l_ascii.
ENDDO.
[/P]
Here, for each character of string p_ascii, the internal (ASCII) representation is determined and written to the output list.

Clemens

Problem convertting certain extended ascii characters

I'm having problems with the extended ascii characters in the range 128-159. I'm working with SQL server environment using java. I originally had problems with characters in the range 128-159 when I did a 'select char_col from my_table' I always get junk when I try to retreive it from the ResultSet using the code 'String str = rs.getString(1)'. For example char_col would have the ascii character (in hex) '0x83' but when I retrieved it from the database, my str equaled '0x192'. I'm aware there is a gap in the range 128-159 in ISO-8859-1 charset. I've tracked the problem to be a charset issue converting the extended ascii characters in ISO-8859-1 into java's unicode charset.
I looked on the forum and it said to try to specify the charset when I retreived it from the resultset so I did 'String str = new String(rs.getBytes(), "ISO-8859-1")' and it was able to read the characters 128-159 correctly except for five characters (129, 141, 143, 144, 157). These characters always returned the character 63 or 0x3f. Does anyone who what's happening here? How come these characters didn't work? Is there a workaround this? I need to use only use java and its default charsets and I don't want to switch to the windows Cp1252 charset cuz I'm using the java code in a unix environment as well.
thanks.

Normally your JDBC driver should understand the charset used in the database, and it should use that charset to produce a correct value for the result of getString(). However it does sometimes happen that the database is created by programs in some other language that ignore the database's charset and do their own encoding, bypassing the database's facilities. It is often difficult to deal with that problem, because the custodians of those other programs don't have a problem, everything is consistent for them, and they will not allow you to "repair" the database.
I don't mean to say that really is your problem, it is a possibility though. You are using an SQL Server JDBC driver, aren't you? Does its connection URL allow you to specify the charset? If so, try specifying that SQL-Latin1 thing and see if it works.

Encoding Individual Strings with XML entities to replace "&", " ", etc.

We use templates to create XML files. The tags are in the templates and just the values get substituted in. Sometimes the variable value contains an ampersand or other XML-banned character.
1) Is there a simple method in the Java or Xerces class libraries that takes a string and returns one with the suspect characters replaced by XML entities?
2) Sometimes, though rarely (I have no control over this!) the variables arrive with the forbidden characters already replaced by entities. Is there a method which will tell me if the string already contains entities, or at least is already a valid XML string? Otherwise I'm afraid the ampersand in an already-converted entity name will itself be converted to another entity.
Thanks!

I'm not aware of any built-in mechanism for doing that kind of escaping short of a full XML generator. Here's a lightweight solution that replaces ampersands only if they're not part of an XML entity. Just grab a copy of Elliott Hughes' Rewriter and implement it like this: public class Test
/* Rewriter can be found here:
   * http://elliotth.blogspot.com/2004/07/java-implementation-of-rubys-gsub.html
public static void main(String... args) throws Exception
    Rewriter xmlEscaper = new Rewriter("[<>'\"]|&(?!(?:lt|gt|apos|quot|amp);)")
      public String replacement()
        char ch = group(0).charAt(0);
        switch (ch)
          case '<' : return "&lt;";
          case '>' : return "&gt;";
          case '\'' : return "&apos;";
          case '"' : return "&#38quot;";
          case '&' : return "&#38amp;";
          default :
            throw new IllegalStateException("this can't happen");
    String str = "this & that & the <other&#38gt;";
    System.out.println(xmlEscaper.rewrite(str));
}

well...you are supposed to get everything on one line
since its a just one big string am converting...what
am trying to do here is breaking it up into
individual words...do you get me nowYes I understood that from the beginning.
However the problem is rather simple. And that suggests that figuring it out on your own and using the methodologies to do so (like putting in extra prints) would be helpful to you.

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.
