How can I convert an ASCII string of variable length to a HEX number?

Hello,
I read data from the serial port 5 times in a second (while loop) and the number of bytes read varies every time.
The data comes in as ASCII string, and I can see the HEX representation if I connect a HEX string indicator, but I need to permanently convert data to a HEX number.
How can that be done?

You can use String to Byte Array for this.

CS3/CS4/CS5 Win/Mac: How can I convert a Windows string to mac?

Hi
I have a Windows coded string. I like to convert this string into a Macintosh string. This means several characters are changed, e.g. ä, ö or ü.
Is there a method in the Indesign SDK?

I don't think this should work that way. If this string is in resource file, use UTF-8 encoding and make PMString do its job. use kResourceUTF8Encoded in StringTable:
resource StringTable (kSDKDefStringsResourceID + index_enUS)
        k_enUS,                                             // Locale Id
        kResourceUTF8Encoded,                         // Character encoding converter (irp) I made this WinToMac as we have a bias to generate on Win...

How can I convert output data (string?) from GPIB-read to an 1D array?

Hello all,
I am reading a displayed waveform from my Tektronix Oscilloscope (TDS3032) via the GPIB Read VI. The format of the waveform data is: positive integer data-point representation with the most significant byte transferred first (2 bytes per data point).
The output data of GPIB-Read looks like a string(?) where the integer numbers and a sign like the euro-currency sign are seperated by spaces e.g. #5200004C3 4 4 4 4 3C3C3........ (C represents the euro-currency sign).
How can I convert this waveform data into a 1D/2D array of real double floatingpoint numbers (DBL) so I can handle the waveform data for data-analysis?
It would be very nice if someone know the solution for this.

Hi,
First of all, I'm assuming you are using LabVIEW.
The first you need to do is parse the string returned by the instrument. In this case you need to search for the known symbols in the string (like the euro sign) and chop the string to get the numeric strings. Here are some examples on parsing from www.ni.com:
Keyword Search: parsing
Once you parse the numeric strings you can use the "String/number conversion VIs" in the String pallette.
Hope this helps.

How can i convert an ascii character to a number?

where can I find the function?

A string will be converted to an array of U8.
Unless you convert a single character.

How can I Convert a numeric string to a formatted string?

I have a string value returned from a background tool that will range from 0 to possibly terabytes as a full number. I want to format that number to use commas and to reduce the character count using an appropriate size modifier (KiB, MiB, GiB, etc). I've tried converting the string number to a Double value using Double.parseDouble() and then performing the math based on the size of the value with this code:
Double dblConversionSize;
String stCinvertedSize;
dblConversionSize = Double.parseDouble(theValue);
if (dblConversionSize > (1024 * 1024 * 1024))
stConvertedSize = String.format("%,.000d", dblConversionSize / 1024 / 1024 / 1024) + " TiB";
I've also tried using
String.valueOf(dblConversionSize / 1024 / 1024 / 1024) + " TiB";
However, the formatting is failing and I'm either getting a format exception or the result is displayed as a number with no decimal component.
Anyone have a recipe for this?
Thanks,
Tim

TOLIS Tim wrote:
Thanks, but the reason for using Double is that the division math can leave me with values like 2.341 GiB. I don't want to drop the values (or round) on the right side of the decimal point.
Then you may look for DigDecimal which avoids digitization errors.
NumberFormat will handle all subclasses of Number. You might need another specialization. Just look at the API which one is suitable.

How can I convert an ArrayList to a String[]

Hi,
How can I convert an ArrayList (only with strings) to a String[] ?
I've tried this :
     public static String listToString(List l) {
          StringBuffer sb = new StringBuffer();
          Iterator iter = l.iterator();
          while (iter.hasNext()) {
               sb.append(iter.next().toString());
               if (iter.hasNext()) {
                    sb.append(',');
          return sb.toString();
But what I get is an array of xxxxx@435634 (for example).
Thanks a lot !

Strings are Objects but not all Objects are Strings and at least one of the elements in your List is not a String.

How can I convert string to the record store with multiple records in it?

Hi Everyone,
How can I convert the string to the record store, with multiple records? I mean I have a string like as below:
"SecA: [Y,Y,Y,N][good,good,bad,bad] SecB: [Y,Y,N][good,good,cant say] SecC: [Y,N][true,false]"
now I want to create a record store with three records in it for each i.e. SecA, SecB, SecC. So that I can retrieve them easily using enumerateRecord.
Please guide me and give me some links or suggestions to achieve the above thing.
Best Regards

Hi,
I'd not use multiple records for this case. Managing more records needs more and redundant effort.
Just use single record. Create ByteArrayOutputStream->DataOutputStream and put multiple strings via writeUTF() (plus any other data like number of records at the beginning...), then save the byte array to the record...
It's easier, it's faster (runtime), it's better manageable...

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.

With respect to one complement and two complement ?

Just like Jeff, purely guessing here.
It almost sounds like you just need to Read from Binary File?
AND the 8-bit number with 1?
Need more details. What exactly do you have to start with? What exactly are you trying to get out of it? Examples help.

How can I convert a string to a separated characters without using array?
such as: input = String "word"
output =

d
Thanks

A string is stored internally in individual characters.
The String class has a method 'charAt(int index)' which returns the character at that index so using a for loop..
String s = "word";
for(int counter=0; counter < s.length(); counter++)
System.out.println(s.charAt(counter));
