Applet read and write

Which possibilities did I have when I want to read and write Files from the harddisk?? ( It must run in an Applet)
Please describe the way(s) to access 'io' in applets.
Thanks a lot!!!

You can't do "normal" io from an applet or japplet. There are ways of getting around it though. Look at this post - it will help:

Read and Write Files to user from Forms Server

We are developing an application that requires us to rread and write files to the user system. We are deploying using the developer/forms server and this is not happenning. The text_io package and the d2wkutil operate on the application server system, not the user system. So is there a method to read the file contents into the app and write files out to the user system across the web. Thanks.

developer6 can interact with javabeans. the javabean runs as an applet on the client machine. all you have to do is setup a javabean that read and write to your client machine.
when you test your application, work with java console open so you'll be able to debug your appliacion, if you'll receive java security execption you may need to sign this javabean. look at sun site for info regarding the usage of javakey for signing java classes and jars.

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.

In iCal and Notifications on a notebook, is it possible to expand the notes window to make it easier to read and write notes?

In iCal and Notifications on a notebook, is it possible to expand the notes window to make it easier to read and write notes? In the past, I have used Outlook calendar and tasks and I was able to expand the windows which allowed me to put a great amount of details into either the notes section in events and tasks. It would be great to be able to do this in iCal and Notifications as well. I am using a Macbook Pro with OS X 10.8. Thank you very much for assistance with this.

Also, Im a photographer, so I like to name a lot of files at the same time (used to do in on PC and it was very usefull.) cannot find out how to do it on my Mac. Really appretiate if some one can give me a solution! Thanx

Your drive is formatted with the NTFS file system. OS X can read but not write to the NTFS file system. There are third party drivers available that claim to add the ability to OS X to write to an NTFS partition. I have not tried them and don't know if they work.
The only file system that OS X and Windows can both write to natively is the FAT32 file system.

Mac desktop. 10.6.8. Text edit. Not locked. Read and write. Still, documents are locking when they are moved from desktop to another folder on the server. Techies can't figure it out here. What am I not doing?

Mac desktop. 10.6.8. Text edit. Not locked. Read and write, not read only. Documents are locking when they are moved from desktop to another folder or saved directly into that folder on the server. Not happening with anyone else but me and the boss's computer so has to be in the properties for my text edit software. Techies can't figure it out after trying for two weeks. Boss can do a cut and paste and put into a new document, but that's starting to become a problem.

Need help to read and write using UTF-16LE

Hello,
I am in need of yr help.
In my application i am using UTF-16LE to export and import the data when i am doing immediate.
And sometimes i need to do the import in an scheduled formate..i.e the export and imort will happend in the specified time.
But in my application when i am doing scheduled import, they used the URL class to build the URL for that file and copy the data to one temp file to do the event later.
The importing file is in UTF-16LE formate and i need to write the code for that encoding formate.
The problem is when i am doing scheduled import i need to copy the data of the file into one temp place and they doing the import.
When copying the data from one file to the temp i cant use the UTF-16LE encoding into the URL .And if i get the path from the URl and creating the reader and writer its giving the FileNotFound exception.
Here is the excisting code,
protected void copyFile(String rootURL, String fileName) {
URL url = null;
try {
url = new URL(rootURL);
} catch(java.net.MalformedURLException ex) {
if(url != null) {
BufferedWriter out = null;
BufferedReader in = null;
try {
out = new BufferedWriter(new FileWriter(fileName));
in = new BufferedReader(new InputStreamReader(url.openStream()));
String line;
do {
line = in.readLine();
if(line != null) {
out.write(line, 0, line.length());
out.newLine();
} while(line != null);
in.close();
out.close();
} catch(Exception ex) {
Here String rootURL is the real file name from where i have to get the data and its UTF-16LE formate.And String fileName is the tem filename and it logical one.
I think i tried to describe the problem.
Plz anyone help me.
Thanks in advance.

Hello,
thanks for yr reply...
I did the as per yr words using StreamWriter but the problem is i need a temp file name to create writer to write into that.
but its an logical one and its not in real so if i create Streamwriten in that its through FileNotFound exception.
The only problem is the existing code build using URL and i can change all the lines and its very difficult because its vast amount of data.
Is anyother way to solve this issue?
Once again thanks..

How do I read and write at the same time using the NI-CAN channel API?

Here's the situation. I have one CAN bus, and I need to read and write channel data (using the channel API) at the same time both at an interval of 20 ms. It's easy to do one or the other using the channel API, but you can't setup a channel task to do both. It's either input or output, not both. Is this even possible?

Hi,
yes , this is possible. But you have to create two tasks, one for input and one for output. see the attached example for LabVIEW.
If you download and install NI-CAN 2.4 you will get this example and one for C and VB as well.

How do I set an external HD permission to read AND write?

I received an iMac for Christmas and need a little help. I have a 2TB external HD that contains .shn and .flac files of GD concerts (and other music). I managed to find Cog that will play them...but what I want to do is download them and move them upon completion to the external HD. I can not do this because the HD is read only. I can move stuff to a SD card because it is read and write. I assume when I change the permission I will be able to move the folder of a show to the HD as well. Surely this is simple... Thank You and sorry for the dumb question!

Your external hard drive is likely NTFS formatted for use with a PC.
OSX can read but cannot write to NTFS formatted volumes. You can install software that allows writing to a NTFS drive, as Niel has suggested, or you can reformat your external drive using Disk Utility for use with your Mac.
If you decide to reformat your drive for Mac use, copy your data off to another drive before you proceed.

How to share files in a network and allow read-and-write to a specific computer only?

I have several computers in my network, and I want to share a folder and allow read-and-write from computer A to Computer B only, and omit computer C. How do I do that? Thanks.

Thanks for the suggestion. I like this approach as Java is more familiar to me than other languages.
Our DBA is out of touch today, so I could not grant the javauserpriv to my database user. I tried to run the script anyway in the chance that my user had the privs, and it seemed to have hung. I am now combing Oracle's site for more documentation so I can write some tests to see if I can get a basic Java object working. Under what heading would I find this?

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

How can i format an external drive so as to read and write from both windows and mac side

i recently bought a macbook pro and used bootcamp so as to be able to run win7 and mac. I now wish to have an external drive so as to backup and tranfer files between the two os's. Specifically to read and write form either windows or mac. How can I do this?

Format it as FAT.

Modbus Ethernet read and write to a Eurotherm 6180XIO Modbus server using LV8.2 shared variables

I am having EXTREME difficulty trying to establish communications with a Modbus device using LV8.2 shared variables. The device is a Eurotherm 6180XIO Datalogger configured as a Modbus master. The PC and a cFP-1804 are slaves. All IP addresses are set correctly. This approach using shared variables would seem simple, but I can't find any examples or proper guidance on how to get it working. I am trying to avoid having to mess around with TCP/IP, OPC, or any other old-fashioned method.
I have read many threads on related topics but none directly apply to this situation. I have created a library containing a Modbus I/O server and shared variables bound to read and write holding registers. I have followed all recommended tips for creating such variables but I can neither read or write data. All data types are U16 due to Modbus protocol limitations. I have also applied the LV x10 factor in the most significant digit in the register offset (6 digits instead of 5).
I have a cFP-1804 on the same network which reads into the datalogger OK. The registers I use are 31000 (for CH0 on module 0, 31002 for CH1, etc) and the data can be read as FLOAT32. I have updated the firmwate on the 1804 to the latest level. I cannot even get shared variables to read SGL values. Using registers 301001 for CH0 and 301002 for CH1 I can only read U16 values, and not a 2-word SGL.
Third party Modbus simulation software is able to write to and read from registers very easily, but not LabVIEW.
Some questions are:
- do I use a Modbus master or slave as an I/O server in the library as a target for binding the shared variables?
- is there some other wierd translation in register offsets between LabVIEW and traditional Modbus?
- is this actually possible using shared variables or am I wasting my time?

Sending the whole 60-character string using a string or array would be the most efficient. I have tried both methods, and these only cause the datalogger to flag a message log but no text is displayed.
For a string variable, I have used the following binding "My Computer\Modbus Test.lvlib\ModbusServer6180\442305", where ModbusServer6180 is a Modbus I/O server configured with the logger IP address, and 42304 is the register offset at the start of the text block in the logger. I need to write to 30 consecutive registers starting with this one. I am not using buffering and have not enabled single writer.
Can anyone confirm whether this method should work in 8.2?
Does the string need a special termination character?
