File to file transfer using UDF

Hi
i am doing one scenario,file tofile transfer using UDF.
I will write one UDF which will read the whole content from text file and write to the target path.Ok.so i am mentioning both sender and reciver URL in UDF.is this the correct way.
then if am writing URL in UDF then is it again need to create communication channel for both.
and how i will do mapping using UDF..plz let me know weather my concept is correct or not

Hi,
You can do this with out UDF and through File--File Simple Scenario
What is your Typical requirement to use the UDF here.
If there is no Specific UDF Requirement means , we can follow Normal Scenario to pick the file from One place and to place it at another folder
File to File scenario:

I woke up at 3am to find my MacBook Pro in the middle of a file transfer using AirDrop.

I woke up at 3am to find my MacBook Pro in the middle of a file transfer using AirDrop. I had not accepted any file transfers via AirDrop as I was asleep so I am a bit confused by all the posts that say that the only way it will work is by the end user accepting a request to transfer files. I am on a home network which has both a soft and hard firewall. I checked my firewall logs and have no signs of intrusion or intrusion attempts. I checked my network map to see see if someone had brute forced my router and was using it but the only assets listed were mine. My router is set up to not be accessable from wireless computers, and is filtered to only allow use by a assets in the MAC Address list. I am an IT by trade but this is my first mac so I am not completely savy in the ways of the ways of macdom. I have found several posts with suggestions on how to turn off and came up with the following terminal command "defaults write com.apple.NetworkBrowser DisableAirDrop -boolean YES". My question is this, how is it possible that my AirDrop was activated and in the middle of a file tranfer if I did not initiate it? I do have a MacMini on my network but its WiFi is turned off so the transfer was not with it. I have read on different posts that you cannot AirDrop if the computer is not on the same network but there were no foreign assets on my network. So my question is this
1. If AirDrop can not be used with another computer if it is not on the same network, how was it being used?
2. How can AirDrop be used to xfer files if I did not accept or initate it?
It seems to be a pretty big security hole to me. Any suggestions or help would be greatly appreciated.

It could just be a bad disc - I use Verbatim and have only had one fail in a ten-year time period. Try getting a batch of Verbatims and see if you have any problems. I didn't even know that there were Kodak branded discs...

HT204144 File transfer using Airdrop from iphone to Macbook Pro

File transfer using airdrop form Macbook Pro to iphone is working...but from iphone to Macbook Pro is not working, Why?

Hi Brok25;
Thanks for the question. The resource below explains the specs and settings that are needed for AirDrop. Check the settings and look to see if your MacBook Pro is listed.
Mac Basics: AirDrop lets you send files from your Mac to nearby Macs and iOS devices - Apple Support
http://support.apple.com/en-us/HT203106
Sending files to and from an older Mac
If a Mac you're using with AirDrop was manufactured before 2012, you can send and receive files with other Mac computers.
On the sending Mac, click "Don't see who you're looking for" in the AirDrop window.
Select the option to "Search for an Older Mac."
On the receiving Mac, open a new Finder window and click AirDrop in the sidebar.
Tips for sending files
Make sure Wi-Fi and Bluetooth are enabled on your Mac and your iOS device. Although you don't have to connect to a specific network, Wi-Fi needs to be on to send and receive files using AirDrop.
Move your devices closer together. AirDrop is designed to work within a range of approximately 30 feet (9 meters). If you need to send a file to someone farther away, consider using File Sharing, iCloud, or email instead.
If you're using a firewall on your Mac, you won't be able to receive AirDrop files if you have enabled "Block all incoming connections" in the Security & Privacy pane of System Preferences.
Make sure your devices meet system requirements for AirDrop.
System Requirements
To see if your Mac works with AirDrop, make sure you’re in the Finder by clicking the desktop (the background area of your screen), or by clicking the Finder icon in the Dock. Then, check to see if AirDrop is listed as an option in the Go menu. If you don't see AirDrop listed, your Mac doesn't support this feature.
In order to transfer files between a Mac and and an iPhone, iPad or iPod touch
your iOS device needs to include a lightning connector
your iOS device needs iOS 7 or later installed
your Mac needs to be a 2012 or later model with OS X Yosemite installed
Your Mac and iOS device both need bluetooth and Wi-Fi turned on. You do not have to be connected to a specific Wi-Fi network.
To transfer files between two Mac computers, you need the Mac models listed below with Wi-Fi turned on and OS X Lion or later installed.
MacBook Pro (Late 2008 or newer)*
MacBook Air (Late 2010 or newer)
MacBook (Late 2008 or newer)*
iMac (Early 2009 or newer)
Mac Mini (Mid 2010 or newer)
Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)
*The MacBook Pro (17-Inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.
For help identifying your Mac, choose About This Mac from the Apple menu. You can refer to the Apple Support website to find out if your iPhone, iPad or iPod Touch includes a lightning connector.
Cheers,
- Judy

File transfer using tcp that implements in swing

Can anybody send me the file transfer using tcp that implements in swing codes

I'm assuming that you're inputing a plain ASCII text SQL file. It's easier to use Readers if you're dealing with plain text, the Output and Input Streams are for Byte input and output. So:
BufferedReader myReader = new BufferedReader(new FileReader("myFile.sql"));
BufferedWriter myWriter = new BufferedWriter(new InputStreamWriter(mySocket.getInputStream()));
String inString;
while((inString = myReader.readLine()) != null)
myServerWriter.write(inString);
myServerWriter.writeLine();
myServerWriter.flush();
Then, in the server you can use the same method that I'm using for the Buffered Reader to read in the file, and use a BufferedWriter wraped around a FileWriter to output the text to that file. Bravo.

Data loss in the secure file transfer using java

Hi,
My java Appllication uses the sftp(secure file transfer protocol) for file transferring. when the load is high like 150 GB , data loss occuring for some files especially last chunk of data is missing.
Core file transfer code
while (true)
int read = bis.read(buffer); //Reading bytes into the byte array (buffer) from network stream (bis).
if (read==-1) {
break; //Break the loop, if there are no more bytes available in the InputStream.
bos.write(buffer,0,read); //Writing the same number of bytes what we read into buffer byte array into OutputStream
complete.update(buffer,0,read); //Giving the same number of bytes what we read above to the checksum calculation.
bytesSoFar += read; //Incrementing the bytes that we have read from the source.
//if the bytes transferred are equal to the source file size
If (bytesSoFar == fileInfo.getFileSize().intValue())
// Calculate the file checksum.
// Update DbAuditLog with checksum and no. of bytes read
else
// Update DbAuditLog with no. of bytes read
bos.flush();
Please help , why the data loss is happening when the big size files transfer
Note:
1.150 gb not a single file multiple files.
2.SFTP no java specific API, So connection is happening through java .io.sockect connection

so, if you are not getting any exceptions, yet the data is incorrect, it sounds like you are having actual network issues. i'd start looking at things like the actual network cards in the computer as well other equipment involved in the transfer. since you are not getting exceptions, the network stack obviously thinks nothing was lost over the wire, so either the actual hardware has issues, or the network stack, or the issue is on the sending end. the last possibility is that the client is somehow munging the data it is sending. do you control the client code? if so, i'd start checking the client side code for bugs (and/or post it here).
also, i'm assuming that all of the variables included in your original code are thread local (you aren't sharing any of those buffers/streams/etc between multiple threads).

File transfer using non-blocking sockets - data mysteriously vanish

Hello,
I need to pass some big amount of data using sockets. I my appliaction I have noticed that sometimes I didn't get all bytes. To check it out I wrote simple client + server to figure out what is happening. So:
- I have a sender and receiver application
- I'm trying to transfer 5MB text file.
- On receiver side, output file is never larget than 3MB
- If I put some timeout on sender side (1ms timeout between write operations) everything works fine.
Could someone tell me what I do wrong? Why data disappears and when? The same file transfered using old sockets goes always fine...
Thanks in advance!

}

There are at least two problems here.
A. In the receiver you should test for -1 from the read() immediately, rather than continue with the loop and try to write -1 bytes to the file.
B. In the sender you are ignoring the return value of client.write(), which can be anything from 0 to the buffer length. If you get 0 you should wait for another OP_WRITE to trigger; if you get a 'short write' you need to retry it until you've got nothing left to write from the current buffer, before you read any more data. This is where the data is vanishing.

File transfer using internet tool kit

HI
i just need to do simple file transfer between 02 pcs connected over a network ....... i am using the internet toolkit .... i have seen the shipped example FTP browser.vi but i am not quite sure how to work with it .
consider that i have only to pc's one with ip add 192.168.0.1 and other with 192.167.0.2.... and i want to transfer a file form one to another or vice-versa.....
Also i came across that to use ftp vi's i should have guideftp(ftp server) installed on my pc (http://zone.ni.com/devzone/cda/tut/p/id/3534). what the purpose of using this server??
and how can i achieve the simple task of sending a file from one pc to the other using labview?
regards
Regards

thanks
The FTP VIs in the internet toolkit implement a FTP client. The FTP protocol is a client/server protocol. In order to use the FTP VIs there needs to be a FTP server for it to connect to. That is the purpose that the guideftp tool you mention is providing.

File transfer using WIFI

When I'm connected to my PC for WIFI file transfer. The program does not MAP to my hard drive

Make sure AP isolation on router is Off
Also you need file andwireless sharing enabled in PB settings Storage and Sharing.
Then go to settings, wifi, and ? info icon, then Internet Connection dropdown to get PB ip address...
192.168.xxx.xxx
Map drive in My Computer to \\192.168.xxx.xxx\media
That should be all you need to do.

Canon Raw File Transfer using Canon 7D / Lion / Aperture 3.2

Is anyone finding issues in unloading raw files with a Canon camera and the latest software? I have been doing this successfully for some time using Aperture 3.1 with Snow Leopard. I use a 13" MBP with 8GB of memory and a huge hard drive. I upgraded to Lion and Aperture 3.2 and find that my Canon 7D doesn't transfer all of my pictures off of the camera. The camera is connected via the USB cable that plugs directly into the camera. I have found a workaround by re-importing off the camera and selecting the option to not download previously imported pictures. Depending on the number of photos, I may have to do it up to 10 times to get all the pictures. I have the latest Canon 7D firmware. I'm able to successfully do this using Canon Utilities running on Lion. Ironically, this same issue happens when I import into Aperture from the camera or from the hard drive. After importing onto my hard drive using Canon software and getting all the pictures in one try, I then tried to import from the hard drive into Aperture but faced the same issue. I think I have this isolated to an Aperture 3.2 issue with Lion and Canon 7D raw images. I also thought that it might be due to lack of battery life on the camera or with large photo shoots. Nope. It happens as well with a small number of photos and a healthy battery.
Is anyone else running into this issue? Thanks.

Binary file transfer using RMI

Thanx in advance !!!
My Query:
Is there any restriction on the maximum size of a binary file that can be transferred over RMI?
In an application (and as per the requirements), I am converting the file contents to a byte array on the client machine and transferring using RMI method calls. At the server side, I am reconstructing the file using the same byte array.
Writing a Java FTP application is out of question.
So please advise.
Vikas

RMI uses TCP/IP so the default should be close to the standard IP limit.

Need hlep for PGP Encryption for delimited file transfer using B2b

I have a requirement to read the PGP encrypted delimited file from partner and decrypt it to process. Can any body tell me how can I do this in b2b. I really appreciate the help

Better read it as a binary document and pass it to the back-end for further processing (decryption and processing). If you want to the decryption at B2B layer itself then use the java callout feature -
