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.

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/pts devpts defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/cdrom /media/cdrom auto ro,user,noauto,unhide 0 0
/dev/dvd /media/dvd auto ro,user,noauto,unhide 0 0
/dev/mapper/nvidia_fbgfhehd1 /boot ext2 defaults 0 1
/dev/mapper/nvidia_fbgfhehd2 / reiserfs defaults 0 1
/dev/mapper/nvidia_fbgfhehd3 /var reiserfs defaults 0 1
/dev/mapper/nvidia_fbgfhehd5 /opt reiserfs defaults 0 1
/dev/mapper/nvidia_fbgfhehd6 swap swap defaults 0 0
/dev/mapper/nvidia_fbgfhehd7 /home reiserfs defaults 0 1
/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 do I read and write to text files on a remote computer's hard drive

I would like to read and write data to a text file on a remote computer. This is easily accomplished using one of the file functions such as "write characters to file.vi". If I am already connected to the remote computer, all I need to do is specify the path to the particular file and it will work fine.
My problem is that I want to connect to the remote computer programatically within LabVIEW (I do not want to have to use the computer's OS to establish the connection. Is there a function that I can use to do this?

Yariv,
You should really start a new thread with a new question like this, so that more people see it. Some people look primarily at threads that have no responses yet. Also, don't post the exact same question in multiple places. Or, if you must cross-post to some other forum, make sure to mention it in your question text.
I'm happy to be a brick in your Western Wall, but I'm not sure what the main objective is here. Is the main problem really getting access to the "X bytes received in Y seconds at Z bytes/sec" string? Or is it accomplishing the file transfer? And what OS and LabVIEW version are you running?
I think your problem is that you the LabVIEW System Exec command does not allow for the degree of interactivity that you need if you want to issue a sequence of commands to a command-line executable. However, under Windows XP (and, presumably, other Windows versions, though I can't check), you can tell the FTP executable to use commands from a textfile script by using the -s switch, and you can override the prompts during multiple file transfers with the -i switch:
ftp -i -s:FILEPATH SERVERNAME
If you issue a command in this format to System Exec, and make sure to create a file at FILEPATH with your command sequence (one per line), then you should at least accomplish the FTP actions. This won't give you the transfer details in the standard output, unfortunately. However, if you just want a general sense of how much was transferred and how quickly it happened, you can code that in LabVIEW by getting the resulting file sizes and using Tick Count before and after the System Exec call to see how long the transfer took.
Hope that helps,
John

I have download NewtonSoft.json version 5.0.8.
So, I am able to convert input data into json format, but how can I able to write and read this data from a json/text file.
How can I do?
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.

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.

HELP!: How to read and write to External hard drives? What file system to use?

hey all, this has been really frustrating for me today. i want to be able to write to an external HDD that's formatted in NTFS. today i find out it isn't possible to write to this file system on a Mac and that on FAT32 it is possible. however, FAT32 can't address files larger than 4GB so this hurts me a lot. are there any other file systems that'll allow me to read and write from a Mac? my goal was to use freeNAS to build a NAS with an old tower and connect my external hard drives to it, but if i can't write to them this may not be possible.
thanks guys, i'd appreciate any help!

Mac Mini Sever - Public Share - how enable read and write permissions for new remote files

Hi,
this Sunday a friend ask me to help hum with a problem on is Man Mini Server. He has a small office and uses the mini server to share a public folder to all his employees.
Everyone that creates a file, saves it to the public folder at the mini mac.
That problem is that, who creates the file owns it and remains with read-only permissions to everyone else. The owner has to change the file permission in order to the rest of the employees can work on it.
I do not know mac arquitecture, I only work with windows and linux, but i suspect the principles are the same.
We try to create another folder , and share it, but it happens the same. Have you any ideas on what is wrong?
I suspect it has anything to do with de file Sharing at the mini mac, but it has read and write permissions for everyone.
Thanks for your help.

signed applet. You aren't going to find any easy way to distribute that policy file to users, and that policy file, if you asked me to put it on my PC, I'd tell you to take a flying leap. That would open any applet to access.

How to read and write on sockets?

Hi.
I want to read and write data from sockets, Can anybody help me.
Regards.
Bilal Ghazi.

You need 3 classes. Receiver, RemoteThread and Sender. These classes are not tested by me
//these classes are on the clientside
public class Receiver{//listens to connections
ServerSocket serverSocket = new ServerSocket(port);
while (...){
Socket client=serverSocket.accept();//waits for new connection
RemoteThread thread=new RemoteThread(client);
thread.start();
serverSocket.close();
public class RemoteThread{
final static int BUSYWAITTIME=10;//10 ms
Socket socket;
public RemoteThread(Socket _socket) {
this.socket = _socket;
public void run() {
BufferedOutputStream out = new java.io.BufferedOutputStream(socket.getOutputStream(),socket.getSendBufferSize());
int inBuffSize=socket.getReceiveBufferSize();
BufferedInputStream in = new java.io.BufferedInputStream(socket.getInputStream(),inBuffSize);//wait until get enuff
byte[] buff=new byte[inBuffSize];
while (...) {
//read
while(in.available()<=0 && !stopped){//just wait for it to become ready
try{wait(BUSYWAITTIME);}catch(InterruptedException e){}
int readBytes=in.read(buff);
//do something with the bytes in buff
//This class is on the clientside
public class Sender{
Socket socket = new Socket(host, port);//connects to server
OutputStream out = socket.getOutputStream();
PrintWriter outPrinter=new PrintWriter(out,true);
InputStream in = socket.getInputStream();
//use out or outPrinter to write to server

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.

Read and Write iDVD trouble with backed up iDVD project

Hey guys, I need to open an iDVD project file within my time machine backups for a previously existing user on an external backup hard drive.
When I click it to open I get this message: "An error occurred while loading the project. This project seems to be write-protected and can't be opened."
I've tried right clicking on the file, selecting 'Get info' and changing administrators and 'everyone' to read and write but no luck. Any ideas, suggestions would be greatly appreciated! Thanks!

Correct.
Now I see I missed the wording of the "file not writeable" message, which doesn't sound like a permissions issue. That sounds like it's either not compatible (ie, not for the same version of iDVD), or corrupted.
If you haven't changed versions, try a +*Verify Disk+* on your internal HD, per #A5 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
