Problems when changing hex string to integer.

Hi
I am trying to change a hex string to an integer. I have done this using the following code:
theinteger = Integer.parseInt(thestring, 16);
this works for every hex number up to 7fffffff (Hex). As soon as I go to 80000000 (Hex) a number format exception occurs.
Does any know why this is happening as the highest number I need to go to is ffffffff (Hex).
Thanks

you must parse it to long.
7FFFFFFFF is the highest number that a int can hold.
0x80000000 being the lowest negative number.
Anyway, parsing to long should take care of the problem.

How to add leading zeros to hex string?

Hi, I've got the following problem:
I have a string that represents a 8-digits hexadecimal number. But if the number has less as 8 digits, I need to add the leading zeros. I can't use DecimalFormat, 'cause it works only with decimal numbers. Is there any elegant solution to add the leading zeros to hex string (for example "A3F" to "00000A3F")

Or better use a StringBuffer for that, though I doubt it's a performance problem in your case.

I want to communicate a RS485/2-wire device through COM1. I tried Instrument I/O Assistance to write to COM1(hex string with or without end bye:0D0A), something happened on the bus, but is not defirrential signal, and device didn't recognised them.

I am new to LabView, so please bear with me...
I tried to communicate with an RS485/2-wire device through COM1. I used Instrument I/O Assistant (and Advanced/Basic Serial Write and Read examples) to write command (HEX string) to COM1,
tried writing HEX strings with and withour end bye (is 0D0A the correct end signal for HEX string?). Both didn't get device's responce. Looks like the device didn't recognize the command.
I monitored the transmitted signals on the bus, they were not differential as supposed to be.....
What is the possible reason to cause this? Please help...
The hardware connection is OK, because I am able to communicate with the device through COM1 (with the same command) using different software application.

How are you sending the hex? Is your string control set for hex display or normal? If it's set for normal, then if you send something like 'AD', then you aer sending the ASCII characters 'A' and 'D' and that's not the same thing. I don't believe the I/O assistant can send hex but you can modify the basic serial write and read to do so. Just right click on the string control and select 'Hex Display'. You can also enter the data in a numeric control (set for dex display) and use a type cast or an array of U8's and use the Byte Array to String function. Hex data usually doesn't use any kind of termination characters such as CR/LF.
If communication is working with another app, then as you said, the hardware is okay and it's not a problem with differential signaling.

Single precision to hex string

Hello,
I was wondering how to typecast a SGL Or DBL into a hex string? I tried number to hex, and format into string, etc but can't seem to figure it out.
The stirring doesnt need a sgl/dbl and is fine but the heating needs to work at a decimal point. since the device must multiply the heating by 10 (inputting 80 degrees gives out 800 to the device and it sets it to 80 degrees) turning it into a hex string shouldn't be a problem but i can't seem to figure this out.
Any help would be appreciated.
Thanks

Hex string and normal string concatenate issue

Hello,
what i have is a hex string and a normal string which i want to concatenate into one string. the problem is that in the output concatenated string you need to select either "normal display" or "hex display" in the properties. the problem is if you select hex display then the normal string is converted into hex and if you select normal display then the hex value is not correct. is there a way to display the hex value in normal display mode?
attached is a vi showing the problem

If by "correct output", you mean you want something like 4bytes (0xBADDF00D) converted to 8bytes ("BADDF00D" in normal display), then there are several ways ...

That certainly looks like a low memory issue, 2 GB ram is barely enough to run Mac OS X versions from Lion through Yosemite. The high number of Page Outs and killed processes show very high memory pressure.
Try adding memory, but be sure it is high quality, Mac certified memory such as that from OWC, http://www.macsales.com or Crucial, http://www.crucial.com

Which bytes should be edited in a WMF hex string stored in an RTF file in order to change image dimensions?

I would like to save the WMF file with proper dimensions as they are in the editor (my saved WMFs have the dimensions of my screen resolution). They come from a RichEdit.
Thanks.
Edit:
My goal is to convert the images that appear on a RichEdit to another format.
Here is the fragment of the RTF:
{\pict\wmetafile8\picw7407\pich9259\picwgoal4199\pichgoal5249
010009000003703e020000005a3e02000000050000000b0200000000050000000c022b24ef1c5a
ffffffffffffff030000000000
}\cf2\lang1033\b\f1\fs23\par
For each 2 chars in this string I converted it to hex and saved it through a memory stream. Then I opened it in Paint or GIMP and there is the image. I even can convert it to a PNG file through ImageMagick tool. But the dimensions are wrong. How to fix
this?
I am using Lazarus.
I could guess that the header is not OK, but how they can be opened by Paint and converted? So I guess the dimensions info is wrong in the header. In GIMP even the dimensions are right, here a link to the GIMP's dialogbox confirmation with the dimensions
it has encountered in the file ( http://s13.postimg.org/s536tgo9z/Metafile_in_GIMP.png ).
So the info is there, but is wrong. When I open the images in Paint, they are wrong. Microsoft Office Picture Manager can also open them correctly, but could not convert them so. I need to do it programmatically. TMetafile Delphi class could not open these
files as well in order to be converted. So I could only edit the bytes.
My RichEdit WMF data can not be accepted by ComputeAldusChecksum routine nor get a handle from SetWinMetaFileBits API call, which would convert it to an EMF format.
procedure TMetafile.ReadWMFStream(Stream: TStream; Length: Longint);
var
WMF: TMetafileHeader;
BitMem: Pointer;
MFP: TMetaFilePict;
begin
NewImage;
Stream.Read(WMF, SizeOf(WMF));
if (WMF.Key <> WMFKEY) or (ComputeAldusChecksum(WMF) <> WMF.CheckSum) then
raise EComponentError.Create('Invalid metafile.'); // <<<<<<<<<<<<<<< exception here
Dec(Length, SizeOf(WMF));
GetMem(Bitmem, Length);
with FImage do
try
Stream.Read(BitMem^, Length);
FImage.FInch := WMF.Inch;
if WMF.Inch = 0 then
WMF.Inch := 96;
FWidth := MulDiv(WMF.Box.Right - WMF.Box.Left,25400,WMF.Inch);
FHeight := MulDiv(WMF.Box.Bottom - WMF.Box.Top,25400,WMF.Inch);
with MFP do
begin
MM := MM_ANISOTROPIC;
xExt := 0;
yExt := 0;
hmf := 0;
end;
FHandle := SetWinMetaFileBits(Length, BitMem, 0, MFP);
if FHandle = 0 then
raise EComponentError.Create('Invalid metafile.'); // <<<<<<<<<<<<<< exception here
Enhanced := False;
finally
Freemem(BitMem, Length);
end;
end;

Converting a Hex String to an Int

I have a quick question. I am attempting to encode an Integer as a Hex String using Integer.toHexString(), which produces a max of eight hex characters.
I then need to convert this string back to an integer. I tried using Integer.parseInt(string, 16), but this only works for positive integers, because it expects a negative number to be designated with a "-" sign, which is the behavior of Integer.toString(int, 16).
I do not wish to represent the "-" sign in that manner, because I want to minimize the length of the hex string.
This method is time-critical, and I would like it to be as simple as possible, so I am looking for a solution in the standard libraries. Does anybody know of a method to convert the eight character hex representation which includes the sign bit as part of the eighth character back to an int using a method provided by the libraries?

int intVal = (int)Long.parseLong(str, 16);

How could I choose some bytes from HEX string and then convert it to a decimal value?

Hi I am working with an OMRON E5EN temperature controller using VISA serial to get data, I send the Read from Variable Area command and get this string in hexa 0230 3130 3030 3030 3130 3130 3030 3030 3030 3030 3041 3203 71 or .01000001010000000000A2.q in ASCII this string means:
02 STX
3031 3030 Node and subadress
3030 End Code Normal Completion
3031 3031 Command Read from Variable Area
3030 3030 respt code Normal completion
3030 3030 3030 4132 Hexadecimal A2 = 162 (this is the temperature data that I want to show in decimal)
03 ETX
71 Block Check Character
I want to choose the eight bytes for the temperature data and convert it to a decimal number. I have seen the examples to convert a Hexa string to decimal but I do not know how to choose the specifics bytes that I need.
I have look for a driver but i didn´t find any. I am a beginner so please include especific topics for me to study in your answer.
Thanks
Carlos Fuentes Silva Queretaro Mexico

If the response always has the temperature starting with byte 15 and is always 8 bytes in length, you can use the String Subset function to get those bytes out of the string. Then use Hex String to Number to convert to a decimal number.
Well someone already beat me to the solution:

Non-hex character in hex string after upgrade to Yosemite

Hi,
When I try to open some of my files I get an error: "Acrobat PDF File Format is having difficulties. Non-hex character in a hex string". I could open the files before.
The only thing I've done since I opened the file last was to upgrade to Yosemite. The error occurs on both my Mac Pro (late 2013) and Mac Book Pro with Yosemite. Unfortunately, I have no access to a Mac with Mavericks and CS6 but I will try to fix one to verify that the file works there.
Affected files (Created in Illustrator CS6 on Mavericks):
services.ai
visual guidelines v.0.4.pdf
visual guidelines.ai
Tested steps:
Open previous versions of the same file from our repository
Update Illustrator CS6 to latest version
Download Illustrator CC
Tried to Place the file into another file (same error)
Tried to repair file Enable content recovery mode | Illustrator CS2-CS5

Hi svepdesigncenter,
How you are accessing those files from your repository?
There might be chances of getting files corrupted when transferring.
File may have been sent as ascii when it should have been sent as binary or vice versa.
In 99% of transfers it's ALWAYS safest to zip an AI or eps file before sending it anywhere.

Non-hex character in a hex string error message

Hi everyone,
I encountered n error message in Illustrator "Acrobat PDF File Format is having difficulties. Non-hex character in a hex string." when trying to open a particular file.
File was originally created on a Windows 7 PC, tried opening file on Mac OS 10.7.5, same Illustrator version 18. Also tried opening in PDF, Distiller, but didn't help.
Did tried to change Illustrator Preferences in both Windows and Mac, following the steps in the TecNote:
http://kb2.adobe.com/cps/500/cpsid_50031.html
When trying to open the file from the File > Open menu, with the keys held down, it did not open a blank file window, neither did it created a duplicate copy in the Finder where the file is located.
The file in question had about 15 artboards, a few embedded images, approx 2.6MB size.
Any suggestions/assistance would be greatly appreciated.
Thank you.

Hi Monika,
The file was .ai file, as mentioned earlier, was created in Illustrator ver 18.
Not emailed, stored in the folder, on the Windows PC, not a server. Last saved few days ago, tried to reopen the file from the same computer, but could no longer opened.
No, Illustrator did not crash, just the error message "Acrobat PDF File Format is having difficulties. Non-hex character in a hex string."

Non-hex character in a hex string

My Illustrator file will not open in Illustrator and I get the "non-hex character in a hex string" window whenever I try to open it. It does open in Acrobat but nothing else. I can't even save it as a pdf file..
Is there any way I can get around that or fix it?

karam,
The first thing to try is to use File>Place in a new document and see how much, if anything, is saved this way.
The next thing to try is to repair the file code, which is more difficult. The basics are told in this TechNote, the actual recovery consists of changing/adding/deleting code.

Hex String of format "01:02:03:04:05:06" to Integer?

Yes, that is a Mac Address,
does anyone know if there is some "comfortable" conversion routine in Cocoa for converting Hex numbers from String to int?
The ":" could be stripped, of course, they are only delimiters for easier reading...
Many thanks for any suggestions!
Cheers,
Thomas

After you strip the colons from the string try something like:
NSScanner *scan = [NSScanner scannerWithString:hexValue];
unsigned val;
[scan scanHexInt:&val];
'val' will now contain the integer value of the string. 'hexValue' is the hex string. You might need to prepend "0x" to the start of the string too, after removing the colons.
