Displaying Hex

I want to print each byte of a byte [ ] as hex to the screen. Is there a method to do this without a manual conversion?

Check Integer.toHexString(). If you want to show 160 as A0 and not as
-60, be careful to mask the bytes. If you want a 15 to be 0F, not just F, you also need to take care of it.

Displaying hex in Jtable

Hi
I am wondering what the best way to display hex values in a JTable is. At the moment I am using the Integer.toHexString method to convert an integer to hex but the problem with this is that it gets rid of leading zeros.
Is there a way to keep the number of digits in a hex number column.
I would be greatful for your help.
Thanks

Hi derek,
I've had to do this as well, and the only solution I could come up with is to create a method that would prepend the zeros to the hex string. For example:
public String pad(String str, int len) {
   StringBuffer buff = new StringBuffer(str);
   for(int i = 0; i < (len - str.length()); i++) {
      buff.insert(0, '0');
   return buff.toString();
}Hope this helps,
Bud

Any built in function to display hex num in 0xHH format?

any built in function to display hex num in 0xHH format
or do i have to code a method myself?
thanks

if int say has a value 9,
i want it to display as "0x09" .... instead of 0x9.
tnxExtending the previous answer::
public static void printNumIn0xHHFormat(int num) {
    String prefix = "0x";
    if(num < 16){
        prefix += "0";
    System.out.println(prefix + Integer.toString(num, 16));
}

Can I display Hex wave in Labview?

Can I display Hex wave in Labview(not only Binary wave)? Is there any
way to do that? If I can show you the hex wave graph , you will know
what I mean more clearly. But I can't put it here. Hope you all know.

You don't say what version you are using, but I believe that starting
with LV6.0 there is a graph in the palette called the digital graph. It
can show group lines/busses and the value of the bus can be shown in
various numeric formats including hex.

Display hex and decimal

Hi everybody,
I'm getting real-time data and I would
like to know if it is possible to change the display to show the
results in hex format and decimal, using the same display. I mean, use
a push botton to change between them.
Regards
Felipe

You can also have both in one indicator.
For an example, have a look at this old nugget. The advantage is that you don't need any extra controls and code (such as buttons, property nodes, and associated logic).

Displaying hex values when editing a numeric control

The hex display is removed when editing a numeric control (in Control Settings) in cvi 2012. Is this a bug or am I missing something?
Solved!
Go to Solution.

I have informed our R&D department of the format of the control settings in CVI 2012 . I have filed a Corrective Action Request (CAR# 379345) on this issue, but can not guarantee when this behavior will be fixed. You can check if this issue has been fixed in future versions of CVI by looking for the CAR identification number listed previously in the CVI Bug Fix Information.

DigitalColor Meter not displaying HEX code

In Snow Leopard I was using DigitalColor Meter 3.7.2 which had support for RGB as a Hex Value, 8-bit hex colour as (See Image)
I recently purchased a iMac and although I thought i was going to have Snow Leopard installed it came with Lion. So I though I would try it out for myself.
I when to open my DigitalColor Meter 4.0 on Lion and I am not even given the option. (See Image)
As a web developer I have used this tool every day for years! I was able to cut and paste the hex code to any colour I saw on my screen not matter where it was or what program I was using. The changes made to this tool have basically made it useless to me.
I really don't know why you would take away functionality on a operating system that is used by so many creative people and in a field that is just growing more in popularity.
I really hope I can find a way to get this back or it is just hidden with some terminal command.

You could try using the SL version in Lion. I've not tried that. BTW, if you want to report this issue to Apple's engineering, send a bug report or an enhancement request via its Bug Reporter system. To do this, register as an Apple Developer—it's free and available for all Mac users and gets you a look at some development software. Since you already have an Apple username/ID, use that. Once a member, go to Apple BugReporter and file your bug report or enhancement request. You'll get a response and a follow-up number; thus, starting a dialog with engineering.

Showing Result as Hex in TestStand v4.0

I'm using TestStand v4.0 & CVI v8.5 and having some problem with displaying hex result in TestStand.
In the code,
td->measurement = 0xAA; // td is tTestData passed from TestStand
In the TestStand step,
Limits -> Numeric Format is configured as "Hexadecimal" (%#x).
The limits were shown as hex. However, the test result was shown as decimal.
The same code & step worked in TestStand v3.5. Did I missed anything in the code / step?
Thanks
Eric

Hi,
You have to format the Result.Numeric separately.
Do this by selecting Property Browser, then expand the Results and select Numeric. Then press right mouse click and select Numeric Format.
Hope this helps

Dbxtool register window, no character display option?

Studio 12.2, SPARC
Hello,
Is there any way to display the ASCII character equivalents alongside the hexadecimal register display in dbxtool and Solaris Studio debugger (which appear similar/identical)? In the memory window there is a display choice, but only one at a time. It should be able to display hex and ASCII side by side at the same time. I love dbxtool but not having the register and memory display in both hex and char at the same time is such an obvious opportunity, hasn't anyone requested this? The variable display is fantastic, but it's not a substitute for the register and memory windows.
Hope I missed something and this is already possible.

Hello and thanks for filing the RFE! This will make a great tool even better.
I am new to dbxtool and command line dbx. I tried your example with an -m32 and -m64 program and I am getting an error:
bad print format
Can you please explain more how I can use this? Thank you!

Poeblem on Open Database

hi all,
here is the problem, I used the Database Connectivity Tool to open a Database, which is based on Microsoft Access. Normally, the program can open the database successfully, but some times, like 1 out of 10, it can't open the database, this issue happened randomly and the error code is so weird, like "-2147467259", I have tried to search this error code in Google, but nothing has been found.
When this problem happened, I can't open the database anymore, until it dissappeared by itself.
Can anyone know how to solve this issue?
Thank you guys in advance.
Louis

When searching for ADO related error messages, I generally modify the error out cluster of my top-level vi to display hex instead of decimal; most ADO errors are found via Google using the Hex value rather than the decimal value.
-2147467259 = 0x80004005
search for "Access 80004005"
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Just use String Subset to pull out parts you need. For voltage, you will want index to be 2 with a length of 4. You can then do the conversion however you need to.

Writing bytes out of Serial Port

I'm trying to write an array of numeric (U8) bytes out of the serial
port. The serial routines though only support strings. Labview has a
routine which converts U8 into strings but only upto x7F (which is the
limit of ASCII) and not to xFF.
Anybody have a workaround to this ?
Thanks.

I just tried the "byte array to string" function (under "conversion"
subpalette under "string" subpalette) and did not see this limitation.
You can put an array of U8 on the front panel, change the format to
display Hex, and type any hex code 0 to FF, and send this thru "byte array
to string" and then through "string to byte arry" to get the original
array back. Create an indicator for viewing the intermediate string and
pop up on the string indicator to change it to hex display. You will see
all the "characters" being translated faithfully.

Hex value to Hex display

I read in a text document from a server different HEX values depending on the equipment i used. The Hex value is sent to a VI for TMT commands.
And the entrance which must be presented as HEX display.
I want to "convert" an appended path string with HEX value for example (0000 3D11 03) to HEX display (0000 3D11 03)

Why is "x2^0" Displayed on Fixed point numbers in hex format

I have a requirement to display a fixed point value (unsigned 20bit value) in hex format. At present when I set the numeric indicator to display this I get a "x2^0" string attached to the end.
What is this and is there anyway of turning it off?
I am trying to give a display that replicated some old style hex mechanical switches, by selecting a fixed size font and limiting the display to only be big enough to display the five hex digits (minimum field length 5 with pad with zeros) I get almost what I want (the "X2^0" is hidden of right hand side)
However when I delete characters from the number (to say enter a new number) the "X2^0" part then shows. See attached jpg which shows the format string.
This is by no means a show stopper but just annoying, is there some where to turn this formatting string off?
Dave.

It is showing how many of those bits are for the decimal places. It is kind of important information.
But since you are dealing with an Unsigned Integer (20,20 means there is no fractional part), why not just use a U32. You can set the display of the indicator for that to be %05x to just display the lower 5 hex characters.

Need your suggestions - how to display large file in ASCII and HEX

Hello,
I want to create an application which can read in a large file and switch between displaying ASCII and HEX (formatted a particular way). There are two problems here that I'm not quite sure how to solve.
1. How to switch dynamically between ASCII and HEX. Should the HEX formatter be in the document of the JTextArea(or equivalent), or somewhere in the view? If it's in the view then where? I'd rather not read in the file more than once.
2. How to do some kind of paging scheme for huge files. I'd like to read in part of the file and display it, then when the user scrolls to another area, read in that part of the file.
Thanks!
Jeff
