Convert integers to equivalent characters in string - NOT ASCII code character

I have to output my data and associated string information to a string array and then to a spreadsheet file.
I want to do this by converting integers (and other numbers) to an identical string of characters.
I have tried Type Cast with a string constant as the type input but it DOES NOT WORK. Instead, I get the ASCII character whose numerical designation matches the integer, e.g. integer "50" become capital "P".
I want integer "50" to be string "50".
Please advise and no, I do not want to make arrays of clusters.
Solved!

I found my answer but only after searching for "Number" conversion rather than "Integer" conversions.
In the Programming palette - String Functions - String/Number Conversion - Number to Decimal String:
"Converts number to a string of decimal digits at least width characters wide or wider if necessary. If number is floating-point, it is rounded to a 64-bit integer before conversion."

Need help with converting characters to ASCII code

Hey. Im trying to write a program to make Caesar Ciphers by random numbers. This cipher must also wrap from front to end of ASCII code, so that if, for example, the character being ciphered is Z and its being modified by +3, the result ciphered character is not "]", but "c".
Im planning on reading the text that the user inputs (using ConsoleIO) into a string and then seperating each character into a character[]. Then, i would like to find the ASCII code of each character and print out the ASCII code character of the old ASCII code + the modifier.
So far, this is what i have (sorry for the length, i like to space things out so that its easier on the eyes and more organized... X-( ... ):
public class EvanFinalB {
     static ConsoleIO kbd = new ConsoleIO();
     static String enteredPhrase;
     static int phraseLength;
     public static void main(String[] args)
          System.out.println("Enter a phrase and this program will cipher it into a secret message.");
          System.out.println("/nEnter your phrase here:");
          //read phrase
          enteredPhrase = kbd.toString();
          //find length of entered text
          phraseLength = enteredPhrase.length();
          //declare arrays for the individual characters of the entered text and the ciphered characters
          char[] enteredChar = new char[phraseLength + 1];
          char[] cipheredChar = new char[phraseLength + 1];
          //loop converting of entered text into seperate characters
          for(int x = 1; x <= phraseLength; x++)
               enteredChar[x] = enteredPhrase.charAt(x);
               cipheredChar[x] = cipher(enteredChar[x]);//call cipher() method to find new ciphered character
     //wrap from front to end of ASCII code
     static char cipher(char enteredChar)
          //choose random number to cipher message by
          int modifier = (int)(Math.random() * 26) + 1;
          if(enteredChar + modifier > 90)//90 is the ASCII code for "Z" which is the last capital letter
               cipheredChar = (97 + (modifier - (90 - enteredChar)));//97 is the ASCII code for "a" which is the first lower case letter
          return cipheredChar[1];
}The program is obviously in its early stages but (i started creating it today actually), if there is a simple method or anything that i can use to find the ASCII value of a character in order to use enteredChar so that 'enteredChar' is equal to the ASCII code of the new ciphered character, please help me out...Thanks
P.S. If there's an easier way to go about creating a program for Caesar Ciphers, let me know.

The following code is from my Java textbook Big Java by Cay Horstmann. It is not my code and it's just to guide you in your own cipher.
import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;
   This class encrypts files using the Caesar cipher.
   For decryption, use an encryptor whose key is the
   negative of the encryption key.
public class CaesarCipher
      Constructs a cipher object with a given key.
      @param aKey the encryption key
   public CaesarCipher(int aKey)
      key = aKey;
      Encrypts the contents of a stream.
      @param in the input stream
      @param out the output stream
   public void encryptStream(InputStream in, OutputStream out)
         throws IOException
      boolean done = false;
      while (!done)
         int next = in.read();
         if (next == -1) done = true;
         else
            byte b = (byte) next;
            byte c = encrypt(b);
            out.write(c);
      Encrypts a byte.
      @param b the byte to encrypt
      @return the encrypted byte
   public byte encrypt(byte b)
      return (byte) (b + key);
   private int key;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Scanner;
   This program encrypts a file, using the Caesar cipher.

         System.out.print("Encryption key: ");
         int key = in.nextInt();
         InputStream inStream = new FileInputStream(inFile);
         OutputStream outStream = new FileOutputStream(outFile);

I need a java function that convert string to ASCII,

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

Convertion to ASCII code

Hi everybody,
I have string:s, I convert it to an integer in base 16:
int a = 0;
a = Integer.parseInt(s, 16);
How can I convert the integer: a to it's equvalence ASCII code?
Any help is greatly appreciated.

I think we'lll try that again;-
char c = (char)a;Without other info, and based solely on 'ascii' the following is probably better...
      if (a > 127)
          throw new Exception("Can not map value(" + a + ") to ascii");
      char c = (char)a;

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.

Characters from VISA not in ascii

I am using ARM Cortex Microcontroller. I am sending the numbers into lab view through usb port.
In such case, the strings obtained from VISA Read are not ascii but i can convert them into unsigned int with the help of string to uint premitive.
The numbers to be sent are continuous and they consist of u8, u16 and also float values.
So the problem here is the conversion. only those value which are defined as u8 are displayed correctly.
How do i convert into appropriate values.
E.g. if the value is integer but greater than 255 i should be able to read and display.
If the value is float i should be able to display the proper float number.
I also tried with scan string premitive, also string to number premitive. They can only read ascii and convert, but the characters i am converting are not ascii.
The characters i am receiving look like boxes and for a value of 0 they are empty space.
To convert a number into ASCII in my microcontroller could also be possible but the requirement here is with lab view. Microcontroller currently has huge load of programs.
I would be happy if someone whould help me in this.
Thanks in advance.

Sorry for the mistake to write it is string to byte.
The necessary clippings are as below. The second clipping 'read buffer' is from a series of transformation where, first data is 300, second is 1 and third is 1.23. The output for these as seen in the third picture is 44, 1 and 1. Yes, 300-256 = 44, previously i wrote 45.
According to you, do you mean that the first two byte should correspond to 300 ? and also similar for the float (not only one byte value but with several values in consecutive elements of the array)?
I would be happy if similar clips would be avialable.

How to accept only 4 or less hex characters in string control

Hi,
I want to accept only up to 4 hex characters in a string control. I dont want to use "hex display" property.
How is it possible? I have String control key down? event in event case, I tried it with regular expressions [0-9a-fA-F]{4} but then I have to accept left, right, delete, backspace, home keys as well.

I agree with Dennis that you seem to be making life difficult for yourself. However, you did ask the equivalent (as I understand it) "How can I allow the user to type "1", "2", "Ctrl-A", "B", "Ctrl-C", "D" and get this recognized as the string "12BD". If you really want to do this, here is one way (I was lazy and left the answer as an array of 4 1-character strings). I use PlatMods to exclude having any "modification" key other than Shift down, convert the numeric Char into a string, then count acceptable Hex letters and conditionally add them to the output array, stopping when I have 4 characters.

Converting a Labview time into a string with Measurement Studio C++

In my Measurement Studio-based C++ application, I'll be sent a Labview
time in the format of a double, which I believe is seconds since 1904.
Does Measurement Studio for Visual C++ contain a function that will
convert that time value into a string format? I'd like to end up with
something like "hh:mm:ss:msec". I'm basically looking for the
equivalent of the Labview vi, "Format Time/Date String". If Measurement
Studio doesn't provide this, is there some other (hopefully simple) way
to do this?
I can request that the Labview application send me time in a string
format as well as a double; this will require several changes to the
Labview application sending the timestamp, but if that is a simpler
solution that's the option we'll take.
Thanks in advance,
Adam

Measurement Studio does not have a function for this, but you can do
this yourself by first converting from LV epoch (1/1/1904) to Unix
epoch(1/1/1970) and then using c runtime time functions
UNIXEpochOffset is the difference between the 2 epochs at GMT. To
convert to a UNIX system clock value, just subtract the sum of this
number and your time zone offset in seconds
lvTime is the value returned by LV timestamp
#define UNIXEpochOffset 2082844800
int _tmain(int argc, _TCHAR* argv[])
    __int64 lvTime = 3214396284; //10:48:13.173 AM 11/9/2005
    //GMT offset for Central Time is -6 (3600 seconds). You will need to account for daylight savings time.
    int offset = -3600;
    time_t unixTime = lvTime - UNIXEpochOffset - offset;
    struct tm *newtime = localtime(&unixTime);
    printf(asctime( newtime )); //prints out the time in a string format.
    return 0;

How can I convert the variable expression stored as string back to variable expression

How can I convert the variable expression stored as string back to variable expression?
I am storing the expression enterd in the TSExpresssionEditControl as simple string and want to convert back to expression since I want to get the data type of that expression.

pritam,
I'm not sure what you're trying to do exactly. If you are trying to get the value of a variable and you only have the name of value in a string, then you can use Evaluate() to get its value. If you want the data type, my advise is to use the GetPropertyObject() API method and just pass in the loop up string. Then you'll have a handle to the data object and then proceed from there.

Converting hexadecimal XML data to a string

Hello!
Until now I generated XML data with the FM 'SDIXML_DOM_TO_XML'.
After that I did a loop over the xml_as_table in which I was casting each line of that table to a string.
ASSIGN <line> TO <line_c> CASTING.
After the inftroduction of unicode in our system I get a error:
In the current program an error occured when setting the field symbol <LINE_C> with ASSIGN or ASSIGNING (maybe in combination with the CASTING addition).
When converting the base entry of the field symbol <LINE_C> (number in base table: 32776), it was found that the target type requests a memory alignment of 2
What does it mean? Does somebody have a solution.
I need this function for sending this XML data as string over a simple old CPIC connection.

Number to fractional string not working correctly

I am measuring some parameters from oscillsocpe. i need to write these values to text file for which i am using write to spreadsheet, but what is happening is it is always writing zero value to file, on debugging i found that while converting from number to string it is always writng zero to string indicator, then separately i used that number to fractional string indicator and it is always showing zero in string output , i dont why it is happening.

Thanks for ther reply
Ranjeet singh,
number to fractional string is working correctly, there is some other problem, because inly when i am executing this code converting this rise time value to string then only it is showing zero, otherwise for any random number if i am checking this number to fractional string is working correctly.

i dont need to convert it back to string that i am doing only to check why it is showing zero value on converting number to string , because when i was writing to spreadsheet file it was always writing zero value, so when checked that code it was observed that while converting from array of numbers to spreadsheet string it is always writing zero value that's why i am doing it here just to check why it is not converting to string, but your suggestion helped in focussing the string that i am gettong from VISA read, i can use that in last case if i wont be able to find the solution but main problem is that why i am not able to convert it back to string, why it is showing zero because it is because of this only write to spreadsheet is always showing zero value .

Removing non-numeric characters from string

Hi there,
I need to have the ability to remove non-numeric characters from a string and I do not know how to do this.
Does any one know a way?
Example:

Required String: 0223454607
Thanks in advance

Dear NickM
Try this this will work...........
create or replace function char2num(mstring in varchar2) return integer
is
-- Function to remove Special characters and alphebets from phone no. string field
-- Author - Valid Bharde.(India-Mumbai)
-- Date :- 20 Sept 2006.
-- This Function will return numeric representation.
-- The Folowing program is gifted to NickM with respect to his post on oracle site regarding Removing non-numeric characters from string on the said date
mstatus number :=0;
mnum number:=0;
mrefstring varchar2(50);
begin
mnum := length(mstring);
for x in 1..mnum loop
if (ASCII(substr(upper(mstring),x,1)) >= 48 and ASCII(substr(upper(mstring),x,1)) <= 57) then
mrefstring := mrefstring || substr(mstring,x,1);
end if;
end loop;
return mrefstring;
end;
copy the above program and use it at function for example

HI Subu ,
there is some information gap , what is your source ? are there any transformation in between ?
If its SQL server source and destination and the datatype is as you have mentioned I dont think you should be getting such errors ... to be sure check advance properties of your source and check metada of your source columns
just check simple oledb source as
SELECT TOP 1 ItemCode = cast('111' as nvarchar(50)),DivisionCode = cast('222' AS nvarchar(50)), Salesplan = cast(3.3 As float) FROM sys.sysobjects
and destination as you mentioned ... it should work ...
somewher in your package the source columns metadata is not right .. and you need to convert it or fix the source.
Hope that helps

.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

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
