Read last characters of file

Hello everybody,
I have got a question here, how to read the last bytes of a file.
In my case, I have a file, and at the end of that file there is a MD5 hash. This hash is allways 128 Bit long (32 UTF8 Chars) so it is easy for me to find it. I know how to read the first 128 bytes, and also how to read the last bytes, by loading the file into NSData but this file might be very large so this is no option. The best way would be to take an NSFileHandle object, read out the last bytes and make a string out of it. I can go to the end of file with seekToEndOfFile butis there any way to go back from there? Can I say: go back 32 byte and read from there 32 byte into this NSData? And how. Or is there any othr solution?
Thanks in advance, Jannes

Be warned this statement is wrong:
>This hash is allways 128 Bit long (32 UTF8 Chars)
You cannot use UTF8-aware string functions to read or otherwise manipulate CRC numbers. It's a list of 32 8-bit unsigned characters (or any smaller set of larger memory units, providing you know the endianness of your reader). This is *pure* binary information, whereas UTF8 contains *character codes*. And not every binary number is a valid UTF8 code.

Read last characters from a file

Hey All:
i'm a novice when it comes to powershell- but this is what i'm trying to do.
I have the following command-
gwmi-classwin32_computersystem|selectName|out-filec:\computername.txt
I want to then read the last three characters of the computername from the file. If there is a 'cleaner' approach
please enlighten me.
Thanks for all the help
-Matlock

Hi,
Here's a method you can use:
$name = (Get-WmiObject Win32_ComputerSystem).Name
$shortName = $name.SubString($name.Length - 3)
$shortName
EDIT: Show on the draw, see Tommy's response above.

Mail.app hang if mail attachment have special characters in file name

Hello,
I have upgraded to 10.5.1 from last version of Tiger.
After upgrade is not possible send message with attachment which have a czech special characters in file name (like á, í, é, ý, ú, ů, ě, š, č, ř, ž) with Mail.app. If I try it, CPU is overloaded and I must kill Mail.app process.
The same problem have my friends who are running a clear installation of Leopard 10.5.1.
Thanks for correction.

I have the same problem with Hungarian chars. I tried out Tomas suggestion and it really worked. It is so dissaponting to have this kind of bug in a system like this. They never tested against this situation.
I hope somebody at apple read this discussion and somehow this will be fixed in the near future.

Can't read or write some files, internet is failing, youtube won't load, software I tried to install was in Slovenian, not dutch or english like in my systempreferences settings, pictures and files won't preview with spacebar, etc. Malware?

Specs:
iMac 10.8.5
3,4 GHz Intel Core i7
32 GB 1600 MHz DDR3
Can't read or write some files, internet is failing, youtube won't load, security software I tried to install was in Slovenian, not dutch or english like in my systempreferences settings, pictures and files won't preview with spacebar and are randomly corrupted, when I entered something in the Youtube searchbar (when it was still working) it send me to a site with sexadds.
I tried restart my iMac and when I was logged back in, my dock preferences were reset.
Also tried to download some security software to check my Mac for malware, but when I did, I tried several, I got a notification that said something like 'dumpfiles (don't know if this is the right translation...) damaged'.
I'm taking screenshots from all the weird notifications I get and even three quarters off the screenshots I took in the last three hours are already unreadable.
It started this morning when I tried opening a Premiere Pro file on which I worked the night before.
When I tried opening it, it said the file was damaged and could not be openend.
I tried opening it with AE or importing the file in a new project but nothing helped.
When I tried looking for autosaves, this is the really weird part, there were none.
Even though there are autosaves from my other projects, this one was completely gone.
It looked like the day before never happened on my computer.
Also when I openend Premiere all the recent projects had been wiped.
So at first I thought it was a Premiere Pro failure.
But than, later on the day, I tried loading some RAW files from my compact flash card.
This is where I would get an error (error -36) which said some data cannot be read or written.
I tried importing the files with a view different technics, from dragging to importing via Lightroom and I succeeded with Image Browser.
But when I tried moving the files to an other folder the same error occurred.
While dealing with this issue I wanted to put on some soothing music on youtube.
This is when the next weird thing occurred: youtube wasn't completely loading in Chrome. I refreshed a view times, checked the internet connection and still no difference.
When I tried in Safari it did work but when I clicked enter on the searchbar in Youtube, a page with sexadds appeared (I didn't install AdBlock in Safari...).
I read about this 'phishing' where you are redirected to a site were a possible malware installment can take place...
I don't know if it's connected to any of the problems I've been having but I just never experienced this on a mac, I have been a Mac user for 10 years now.
On top of it all, internet started working worse and worse and now it's not even working at all. I had to fill in the password over and over, normally it remembers.
Just like my system preferences, all the preferences I had with Chrome where also reset.
Also somewhere in between I got this notification: Mac OS X must restore library to run programs. Type your password to allow.
To me this is all very weird and suspicious. I have clearly no idea what's going on. Could this be another sort of trojan horse or malware?
Some background info which could be helpful for solving this mystery:
two months ago the one year old Fusion Drive in my iMac just broke out of nowhere.
I got it replaced by a qualified apple repair store.
When I got my computer back, all the files where gone.
I got on the internet without AdBlock installed yet.
A game or whatever it was, can't clearly remember, got installed by accident.
I deleted it immediately.
Only two weeks later, I couldn't log in to my account. It didn't recognize my password and username.
So I brought my mac back to the store.
Here the repair guy said it was a minor thing and he just needed to reconnect my account. He also mentioned he found a downloaded game name Sparta and it probably had something to do with the error.
I asked him; could it be a virus? He replied no way.
I don't know why I couldn't be a virus, just because it's a mac doesn't mean it cannot be done.
So today I tried installing anti virus software (such as avast- was in a weird language looked like slovenian, clamxav - was in slovenian) but I couldn't install them.
PLEASE help me! I don't know what to do anymore, I work fulltime and I need my computer, I have no time to bring it in for repair, are there other perhaps easier ways?
Could this be the work of a virus or a malware? Or is it a disk permissions issue?

It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

Problem with ArrayLists and writing and reading from a .dat file (I think)

I'm brand new to this forum, but I'm sure hoping someone can help me with a problem I'm having with ArrayLists. This program was originally created with an array of objects that were displayed on a GUI with jtextFields, then cycling thru them via jButtons: First, Next, Previous, Last. Now I need to add the ability to modify, delete and add records. Both iterations of this program needed to write to and read from a .dat file.
It worked just like it was suppose to when I used just the array, but now I need to use a "dynamic array" that will grow or shrink as needed: i.e. an ArrayList.
When I aded the ArrayList I had the ArrayList use toArray() to fill my original array so I could continue to use all the methods I'd created for using with my array. Now I'm getting a nullPointerException every time I try to run my program, which means somewhere I'm NOT filling my array ???? But, I'm writing just fine to my .dat file, which is confusing me to no end!
It's a long program, and I apologize for the length, but here it is. There are also 2 class files, a parent and 1 child below Inventory6. This was written in NetBeans IDE 5.5.1.
Thank you in advance for any help anyone can give me!

BalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.
SomeObject someObject = null; // The someObject reference is null.
someObject.doSomething(); // Invoking a reference which is null would throw NPE.

Need to read Unicode in a file

Hi,
My need to read Unicode from a file (on a Windows box) is due to the fact my software is used in different countries and on different keyboard naturally. All the users are not computer literate but, like me, they are all lazy and want to put their username and password in a config file my application reads. If their username or password contain Unicode characters I have a problem reading.
They are simple users that I would like to advise them to open the config file using Windows Notepad, then type in their username and password, and save the file as Unicode. Notepad has four ways to save a file, ANSI, Unicode, Unicode big endian, and UTF-8 (I've tried them all except ANSI of course). Saving a file in a different format is as complicated as I would like it to get for them, some will have trouble even with this.
I read the file like so:
BufferedReader rdr =
    new BufferedReader(
        new InputStreamReader(new FileInputStream(file_name), "UTF-16"));
String line;
while ((line = rdr.readLine()) != null) {
    String[] pieces = line.split("[=:]");
    if (pieces.length == 2) {
        if (pieces[0].equals("PASSWORD")) {
            byte[] possibleUnicode = pieces[1].getBytes("various encodings");
            pieces[1] = new String(possibleUnicode, "various encodings");
        propertyTable.setProperty(pieces[0], pieces[1]);
}All reading is perfect except for a username or password which can contain a real multi-byte character. I have used many variations of converting the string I get into a byte[] using string_in.getBytes("various encodings tried") and then back to a string but nothing has worked.
I tried a regular FileReader to a BufferedReader and that didn't work. I tried a FileInputStreamto a DataInputStream and that didn't work. I accomplished the most with what I described above, FileInputStream to InputStreamReader to BufferedReader.
Does anyone know how to read Unicode in a file on a Windows file system?
hopi

I have used the byte conversion technique before
successfully when I loaded a set of properties
from a URL openStream(). The properties load()
method takes an InputStream and assumes ISO-8859-1
so I converted the bytes from ISO-8859-1 to UTF-8.
Garbage characters were cleared up perfectly.I think you just got lucky that time. For characters up to U+007F, the UTF-8 encoding is the same as ISO-8859-1 (and most other encodings, for that matter). Characters in the range U+0080 to U+00FF will be encoded with one byte in ISO-8859-1, and with two bytes in UTF-8. In most cases, each of the two bytes in the UTF-8 representation will have values that are valid in ISO-8859-1. The decoded characters will be incorrect (and there will be too many of them), but they effectively preserve the original byte values, making it possible for you to re-encode the characters and then decode them correctly. But there's a big gap in the middle where the UTF-8 bytes produce garbage when decoded as IS)-8859-1. Run the included program to see what I mean.
I don't know what's going wrong with your application, but I do know that changing the encoding retroactively is not the solution. I also think you're right about asking users save files in a certain encoding. Considering how much trouble programmers have with this stuff, it's definitely too much to ask of users.

Reading in a text file to GUI for later analysis

Good Morning any and everyone,
I'm trying to get a piece of code working to read in a text file and it isn't working very well. The code has been seriously crunched together from a multitude of sources so I suspect that the error has occurred from there.
The errors that are occurring are "Can't Find Symbol" errors. Only 2 of them though which is a lot less than I had earlier. Now I'm just banging my head against the wall.
Has anyone got any suggestions as to where I'm going wrong? Anything greatly appreciated.
(PS> Please be gentle, I'm still a newbie)
Thanks.

A couple of points:
*You've commented out stuff that is needed, like the adding of actionlisteners, the implements actionlistener,...
*Your actionlistener is looking for a menu choice which doesn't exist "displayContentsChoice". Does this menu item need to be created?
*How much of this code have you yourself created? Do you understand its inner working?
*What is the purpose of this code? Is it for work? School? Homework?
Good luck!

Regarding reading data from a file in the application server.

Hello Everyone,
My question is:
The file in the application server consists of data with header, detail and trail out of which the detail contains the main information. The detail again contains the data in the form of a continuous string and again some spaces corresponding to a single record. I need to split the data in the internal table in such a way so that the first few characters get into field-1 of the target internal table. Again I need to consider the spaces for accessing the data for filling up in field-2. How do I decide on the 'Split' statement and specially when the whole string has to be taken care of as contatining data in a single string format without space and again some data after some spaces corresponding to a single record.
Your help is very much needed. Thanks to all the experts in advance.

How to get Logic's "Open" command to look in last place a file was opened?

Hi all,
All of the sudden, when I "Open" a file in Logic, instead of looking in the folder I last opened a file Logic takes me way deep into the system library and I have to navigate all the way out by hand to my music folder. How do I set the default file open preference?
And, no, I don't want to use "Open Recent" instead.

Someone else just asked the same question a minute ago, so for the record here's my answer to him. The first part is just what Eriksimon said, but I guess confirmation is no bad thing!
+"How can I change the default ' save as '- destination?"+
Save a file to somewhere different; next time you save a file, this will be the new default.
However, other applications may also have a say in this, so be vigilant!
You can add favourite destinations to the Open/Save dialogue box by opening a window in the Finder & dragging the folder you want into the sidebar. Then whenever you use the Save dialogue, you can just click on that folder — & you're in it.

Hi Ajay,
1. You have to create a separate field catelogus and AIS according to your requirement with the required fields you want . Because the standard structures and field catelogues contains many fields from all tables. So before doing the read operation you have to deactivate the standard AIS and activate your newly created AIS .
2. Can you give some more details for this question to be answered.
3. The important archiving tables used are ARCH_IDX,ARCH_RPRG,ARCH_DEF.
4. While scheduling the Read process in batch mode , it will give you three criterias to be entered.
     . Spool Parameters
     (ii). Start date
     (iii). Archive selection of files.
    Unless you enter values for any one of these options , You cannot execute the batch job.
Hope this would help you.

BIG PROBLEM: CSS files not loading because of international characters in file name

I have Muse Beta 7 in Spanish.
The program creates a css file called master_a-página-maestra.css in css folder. It is referenced in the resulting HTML code here:

<link rel="stylesheet" type="text/css" href="css/site_global.css?3951792836"/>
<link rel="stylesheet" type="text/css" href="css/master_a-p%c3%a1gina-maestra.css?fileVersionPlaceholder"/>
<link rel="stylesheet" type="text/css" href="css/index.css?3948175564"/>
When you work locally in your Windows formatted har drive, everything looks fine, but when you upload your files to a server, everything is screwed up. The server doesn't recognizes the URL and returns an error page, resulting in style errors in the entire site.
This can also happens with html files if the title of the page contains international characters or with images if the image file name in your Hard Drive contains international characters.
I already pointed out long time ago Muse was generating file names with international characters like á, ñ, etc but nobody cared about it. Too bad. I had to activate file name customization but I think that Muse should replace automatically this characters in the same way that it replaces other conflictive characters like commas or ampersands.
This is not a fault of the FTP client. Accented characters are not web safe regardless of the FTP client you are using. It is a server side issue. Some servers support it some others don't. I don't mind if it works in Adobe Catalyst server because the final website is going to be in another server and maybe next year when paid hosting is ended the client may move it to another server.
It makes more sense to replace accented characters in file names by their not accented equivalents ('a' instead of 'á', 'N' instead of 'Ñ', etc) and avoid all this problem.

Zak, It is funny you mention it, because the site I am talking about is hosted in 1and1. try this: http://www.artofwalls.com/rosannawalls/biografía.html
As you can see, the offending "í" in the file name causes 1and1 server to throw a "page not found" error. And this has happened with many other servers I have tried since.
Muse boast of generating code fully compatible with all major web browsers but by using international characters in file names it ggenerates code suitable only for very few web servers. International characters have been always a no-no for internet URLs. Internet was designed by people who didn't care about ascii codes beyond 127 so using international characters in html file names is just call for problems.
"to work with your hosting provider to determine how to enable Unicode encoded (UTF-8) file names and HTML files on their servers" is not a viable solution most of the time unless you are a Very Important Client of your host provider. If not, making changes means money for them and if you are the only one who complains, they are going to just tell you to not use international characters in your names.

Hi Pratim,
Your code is absolutely correct and can be adapted to read in any foreign characters as long as you create your InputStreamReader with the same encoding that was used to write the file you are trying to read. By default, java encodes files in a format called Cp1252. Cp1252 can be used to encode ASCII characters (\u0000->\u007f) + an extended region (\u0080->\u00ff). This extended region contains, among other characters, the extra characters used by languages like Spanish, German etc. To read such a file, change your code to:
InputStreamReader isr = new InputStreamReader(fis, "Cp1252"); However, if one wants to encode characters beyond \u007f (for example, Chinese, Hindu, Russian etc.) then one cannot use Cp1252 encoding. Frequently, such characters are encoded using UTF8 (Unicode Transformation Format 8). UTF8 is capable of encoding the entire unicode character set. There are many many different encodings supported by java. The point is that you must to use the same encoding to read back the characters as was used to store them.
I suggest that you experiment with writing characters to files and reading them back into java using different encodings. You already have the code to read the characters. To write the files, you can either use Microsoft Word or you can write code analogous to your code above except using the OutputStreamWriter. It will also be helpful to you if you have some way of examining the bytes in your output files.

Joe
