How To Read/Modify/Write Array?

Ive got a bunch of switches, where each switch represents a bit in a
word...
So from each switch, in the control panel, it goes throu a boolean to
integer vi, and then to a x*2^n vi.
I then set a constant for each n.. so that if the switch is true (x=1
after the conversion) and n = 5 for that switch,
then the output will be 1 * 2^5.
Finally, I add all 16 outputs together (x*2^0 to x*2^15) to create a
word.. I actually have so many switches
that I have a couple of words (each made up with the above scheme)!
So far, this works fine, however, my question is, I would like to have
a global array that contains these words. I
dont want to insert this word into the array, but rather, I'd like to
sort of latch the values...
If in the array's word, the n bit was already one (i.e. that switch at
one point was on), then I dont want to reset it
to 0, even though the switch is off now.
This probably sounds confusing, I know I am confused just reading that
back, anyhoot, if I could make a global
array (ten 16-bit unsigned words), that I can read any word from,
modify it and set it back to its same place,
that would be great!

Hi Anonoymous
Here's one quick example that does what you want, it functions like a function global and relies on boolean logic.
For your own experience I challenge you how to reset just one bit or word.
Also you have to connect the connector pane.

Thank you for looking into this. Since I was converting into dynamic data before writing it I thought you have to convert it after reading but then I got stuck as to whether build the array again so as to display it in the graph. Dennis I did what you said and the graph on reading is a bit funny just started today and I am kinda skipping the long tutorial due to shortage of time. sorry

How to read and write a string into a txt.file

Hi, I am now using BEA Workshop for Weblogic Platform version10. I am using J2EE is my programming language. The problem I encounter is as the above title; how to read and write a string into a txt.file with a specific root directory? Do you have any sample codes to reference?
I hope someone can answer my question as soon as possible
Thank you very much.

Accessing the file system directly from a web app is a bad idea for several reasons. See http://weblogs.java.net/blog/simongbrown/archive/2003/10/file_access_in.html for a great discussion of the topic.
On Weblogic there seems to be two ways to access files. First, use a File T3 connector from the console. Second, use java.net.URL with the file: protocol. The T3File object has been deprecated and suggests:
Deprecated in WebLogic Server 6.1. Use java.net.URL.openConnection() instead.

How to read and write on ntfs partitions??

Hello everyone, thanks for viewing my post. I want to know how to read and write on ntfs partitions under sata hd on my arch64 system. I'm using kde as my de and dolphin does sees it but can't access it anyway. I didn't had problem so far on mounting usb drives it just automounts maybe because it is a fat partition not a ntfs? Please I need your help...Thanks in advance:)

You will most likely need to rework your fstab. The one from my desktop is shown below. If you want regular users to be able to access the partition, then you will need to change the gid option as I have done. Although you could create a group just for people you want to have access.
You will need to know the device that your windows partition is held on of course. In my case it is my first hard disk, first partition, hence /dev/sda1.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>

none /dev/shm tmpfs defaults 0 0

/dev/sdd1 /mnt/andromeda vfat defaults 0 0
/dev/sda1 /mnt/windows ntfs-3g defaults,user,gid=users 0 0
My XP partition is set to mount automatically, as I regularly interchange documents between the OS's.
Hope that helps.

How to read and write(a file .txt) from a URLConnection

I try to read and write on one URLConnection. Is it possible ? How can i make it ?
The reading part of my application work's but not the writting part
That's a part of rhe code that i use to write :
String Line = "Hi";
MyUrl = new URL(this.getCodeBase(), FichierEvenement) ;
Con = MyUrl.openConnection() ;
Con.setDoOutput(true);
Con.setDoInput(true);
Con.setUseCaches(false);
Dos = new DataOutputStream(new BufferedOutputStream(Con.getOutputStream( )));
Dos.writeUTF(Line);
Please help me :)

What are you doing with the bytes written to the OutputStream? This info would help, but i do have a suggestion. I ran into this problem when trying to write strings using writeUTF. The output was all screwed up. So, maybe change your string to a character array. That way Unicode is displayed properly. This in conjunction with writing to an .html file instead of to the connection itself might work.

Thank you in adv and please, reply soon.

We don't have many samples left for Windows Phone 7 + Azure, the closest one to what you want to do is probably:
Using Local Storage with OData on Windows Phone To Reduce Network Bandwidth
this sample uses the local database feature: 'LINQ to SQL', available to Windows Phone 7.1 and 8.0 Silverlight applications, instead of simple file storage but even if you choose to stick with simple file storage I believe you should be able to adapt the
networking related portions of the sample to your particular application.

          return name;

I'm kind of new at this I just started to learn about
that, is there an example u could give me to inspire
me ?
Object[] o = new String[]{"one", "two", "five"};
Collection ascollection = Arrays.asList(o);
//the returned Collection (List) is unmodifiable,
//so if we want to remove or add items, we need
//a copy:
Collection copy = new ArrayList(ascollection);
copy.remove("two");
String[] backagain = (String[]) copy.toArray(new String[copy.size()]);

How to read and write Unicode text with MS Access?

Hi all, I'm new to Java, so please forgive me if my question is too ... ^_^
I'm writing a small program that read and write data with MS Access. However, when I insert Unicode text into the database, it has wrong encoding like this "h?y l? n?m".
Please tell me how to fix this.
Thanks in advance!

The following forum thread might be enlightening:
http://forum.java.sun.com/thread.jspa?threadID=573855&messageID=2870785
I myself do not use MS Access, but a PreparedStatement is in general the best option.
You can set parameters in the SQL which then get converted and even protected against SQL injection hacking.

Full memory control: how to read and write memory on any address?

I am programming in Visual Basic Express a long time, and now i want something more. I need to read and write bytes in memory on any possible address, and also to get a handle or first byte's addres of any declared object(Integer, String, Bitmap, ...) and
to declare an object to some memory addres. Does anybody know some API function (function that copies blocks of memory from one to another place and gives an address of an object) or any other way to do this, and if knows please write an example code that
CAN be used and it's VALID in Visual Basic 2010 Express or Visual Studio 2013 Express or similar .net basic tools.
Thanks

Hello Donaastor,
the OS might prevent you from writing/reading to "any possible address" because you could read others memory which is not allowed. You will get a security Exception :)
But of course you can read/write every part of "your" memory. Than you should use Joel's answer.
