String to Hex

I was wondering if there is a way to turn a string returned from a .ini file can be converted to an integer(a hexidecimal colour code) for example, the string is
string b = "0x000000"
i used
int k = Integer.parseInt(b);
and it gives nasty errors because of the 0x at the begging, Any help would be greatley appreciated.

You still may need to strip the 0x from the front of the String prior to doing a parseInt(), even with a radix of 16.

Non ASCII String to Hex

Hi,
I am writing an algorithm that first encrypts a String, and then converts that String to Hex String. I can successfully parse Hex Strings into Ascii Strings and vice versa, but when I encrypt I cannot do this anymore. Is there a way to convert a non-ascii character to Hexadecimal and vice versa?
Thanks in advance

Maybe so....
The encrypted value when printed does not format on my screen, and appears as boxes and such.
The values that I am passing in are a very simple encryption....XOR against a key. Here is that algorithm.
public byte[] encrypt(byte[] value) {
          byte[] encrypted = new byte[value.length];
          byte[] adjustedKey = getKey();
          while (adjustedKey.length < encrypted.length) {
               String temp = new String(adjustedKey) + new String(key);
               adjustedKey = temp.getBytes();
          for (int i = 0; i < value.length; i++) {
               encrypted[i] = (byte)(adjustedKey[i] ^ value);
          return encrypted;
Since this is an XOR, I can use the same method to decrypt as well. This is what produces my non-Ascii characters.
Is there a way for me to get the byte value of a 1 digit hex value then? this may help some.

How can I convert a string of hex values to a hex format string programatically?

Is there a way to convert a string of the following format:
1400010107070D0305006A01 ........ ("Normal display" string)
programatically to:
1400 0101 0707 0D03 05006A01 .......... ("Hex display" striing)
I need to do this in order to calculate a CRC16 value.
See attached VIs
Thank you.

You can iterate over the string and use the String to Hex VI. If you work with two bytes of the string at a time you can get a U8 array of the desired binary values. Then when you are complete you can either work with the byte array of convert it back to a string using Byte Array to String.

BIG ASCII string to HEX string

Hello guys,
I know that is already a lot of posts regarding this issue, but I couldn't find exactly what I need and also couldn't manage to solve it myself...
I need to convert a string with ASCII characters to a string containing HEX representation of these characters.
What I did was:
Apparently it works very well, but only for a limited numbers of characters, defined by data representation of the 0 constant (U64). It allows me to convert only 8 ASCII characters, as you can see on the image below:
So, it converted from 0 to 7, but not the remaining characters (8 and 9).
Any ideas??
Thanks in advance!

What is the data type of the constant wired into the typecast. My guess is it is a U64. So it will only typecast the first 8 bytes of your string to a number, then you are doing hex on those 8 numbers.
Use the function String to Byte Array. Or you could also typecast where an array of U8 integers is wired into the typecast function.

How to convert a string to hex in TestStand

Hi everyone, I think this is a fairly easy question to answer but I am newer to TestStand.
In one step I am pulling in the Serial Number of a Device (which is alpha and numeric characters) and storing it as a String Local called Local.SerialNumberString. In the following step I need to convert this Local to a Hex value and store it as Locals.SerialNumberHex
Here is the data representation I need to take place:
Locals.SerialNumberString = ABC123456
and would like to know of a function that would convert to the following:
Locals.SerialNumberHex = 414243313233343536
How can this be done?
Thanks so much!

It looks like what you are asking for is more than just converting to hex, it looks like you want to convert the characters in the string to their ascii value representation and then convert that to hex.
1) Use a for loop Locals.i = 0; Locals.i < Len(Locals.SerialNumberString); Locals.i++
2) Inside the loop do: Locals.SerialNumberHex += Str(Asc(Mid(Locals.SerialNumberString, Locals.i, 1)), "%.2x")
Hope this helps,

You can also directly use "read from spreadsheet file" (but you need to convert to U16 later).

You said you wanted two arrays, so you still need to slice out the two columns.

String to hex cast

Hello,
I am developing an application that talks to a modbus server. Let's say that I build the following command as a string:
0038 0000 0006 FF01 0000 0000
Now I need to change the type of this string from ascii to hex before I send it to the server. How do I do this without changing the actual values??
Does anyone have insight??
Thanks,
Eric

do this without changing the actual values??From the above it appears that each "value" will be decoded and sent in two-byte blocks. Hence, get the short value from each part of the string using the java.lang.Short class.
e.g.
short s1 = Short.parseShort("0038", 16);
short s2 = Short.parseShort("0000", 16);
// and so on for each part of the command.
Then send each of the short's to the server.

Convers ascii string to hex string

I need to send a hex string such as 5051525354A5A6A7A8A9 to a DSP across a serial port. The string is read in from a file.
When I send this string to the DSP, it does not recognize the correct hex values.
If I enter the hex value, 5051525354A5A6A7A8A9, in to a string control that is set to hex display and then change the control to normal display, I get PQRST¥¦§¨©. When I send this string, PQRST¥¦§¨©, to the DSP, it recognizes the correct hex values.
How can I change the hex string read from the text file to this type of ASCII character conversion? I've used type cast and the other functions available in LabVIEW with no success.
This is only one of many strings I need to send so I don't want to hard code PQRST¥¦§¨© or some such string for each message.

Here's a slightly simpler way.

How to convert EBCDIC String in hex to unicode?

How do I convert, for example, "C1C2C3C4C5" (EBCDIC in hex) to "ABCDE"? The input and output types are both String. Thanks in advance!

1. Create a String of 256 characters, where the index corresponds to the ASCII character (e.g. character at index 193 (0xC1) would be 'A').
2. Parse your input string two characters at a time using Integer.parseInt(s, 16) to convert the two digits to a number, and use the resulting number to get the equivalent ASCII character from the translation string in step 1, which can be appended to your output.

Convert HEX String into HEX Array

Hi!
Probably a silly question, but I am looking for a way to convert a ROM ID number such as "5E03C21000BA" into an short hexadecimal array.
The way to do this in C would probably be
char[17] str_romID = "5E03C21000BA";
uchar[8] romID;
sscanf(str_romID, "%02X%02X%02X%02X%02X%02X%02X%02X",
&romID[0], &romID[1], &romID[2], &romID[3],
&romID[4], &romID[5], &romID[6], &romID[7]);
but I can't seem to find a way to do this in LabVIEW. I would be very grateful if you could help me out with a sample program. Thanks ever so much!

Hello Blondchen,
I have attached a picture to my last explanation. This example doesn't take care of strings with an uneven number of chars!
My array has only 6 numbers as you only gave a string with 12 chars... That's what I asked before: how should we know where to split your string to the single numbers? Normally I would take 2 chars to form a byte (as I did in the example). If you give me 16 chars I give you 8 bytes...
I also think your C byte array will be an U8 array in LabView. If you REALLY need I8 numbers you can change the default type of the "hex to string" or cast to I8 (advanced->data manipulation->type cast) after the conversion.
Best regards,
GerdW

Bit-String to Hex

Hello
I've got following question: I have a STRING of bits e.g. "01001010". Is there any function to convert it to Hex - code?

See the attached code. I wasn't sure by what you meant by a "STRING of bits" so it shows two different things.
Remember also that the distinctions between binary, decimal and hex are only significant to human beings reading the numbers--computers don't really care. An unsigned 8-bit value is an unsigned 8-bit value, regardless of how it's represented for human consumption.
Note that in a array the LSB is the first element. In a string, the LSB is the far right-hand digit.

Simple way to turn string to hex

Hello...
I was wondering if there would be nice way to get string, rather long one I might add, to hex form for mobile phone purposes... Preferably to string if possible.
I have looked through forums and have tried to find a nice solution but can't.

To Hex String:
final String nonHexString = "Hello from YoGee";
System.out.print("0x");
for (int i = 0; i < nonHexString.length(); i++) {
System.out.print(Integer.toHexString(nonHexString.charAt(i)));
}Back again:
final String hexString = "0x48656c6c6f2066726f6d20596f476565";
int length = hexString.length();
String[] temp = new String[(length - 2) / 2];
int counter = 2;
for(int i = 1; i < ((length - 2) / 2) +1; i++){
temp[i-1]= hexString.substring(counter,counter+2);
counter = counter + 2;
char[] chars = new char[temp.length];
for(int i = 0; i < temp.length; i++){
chars[i] = (char) Integer.parseInt(temp, 16);
System.out.println(new String(chars));

How conversion a string to Hex?

my string's length is 27.

You could try something like..
    char[] hex = {'0','1','2', /*etc*/ , 'E','F'};
    String str;
    for (int i = 0; i < str.length(); i++) {
        int ch = (int)str.charAt(i);
        for (int j = 4096; j > 0; j >> 4) {
            System.out.print(hex[(ch >> j) && 0x0F]);
    }That should (untested though..) output 108 hex digits for a 27-character string.

Translate string using hex(0020) in Unicode system.

Hello all,
We are facing a problem of the "translate" statement in the Unicode system.
The original statement goes as follows:
TRANSLATE BULOG USING WS_STRING1.
Here BULOG is a structure and ws_string1 is declared as follows:
DATA : ws_string1(2) type x value '0020'.
On compilation in the new system which is Unicode enabled, the above mentioned statement removes all the '#' placed in the structure.
We tried the following statement instead of the original TRANSLATE statement.
TRANSLATE BULOG USING SPACE.
But this statement leaves the '#' unchanged.
We have already REPLACE statement after converting the structure contents into a string.
We have also tried the convert methods of the classes CL_ABAP_CONV_IN_CE and CL_ABAP_CONV_OUT_CE.
Hoping to receive a fast response.
Thanks in advance.
Zankruti.

You might want to read ABAP Help on TRANSLATE:
Addition 2
... USING pattern
Effect
If you specify USING, the characters in text are converted according to the rule specified in pattern.
pattern must be a character-type data object whose contents are interpreted as a sequence of
character pairs.
Your option 1 is not working because type X is "Byte field", technically it's not a character-type. Your option 2 is not working because <pattern> must be a sequence of character pairs (you had just SPACE).
In Option 1 just change the definition from X to C or STRING.
