  • Removing file locks in Windows and Java

    - by Jack
    I have a Java program that opens a file using the RandomAccessFile class. I'd like to be able to rename that file while it is opened by Java. In Unix, this isn't a problem. Does anyone know how I can do this in Windows? Should I set Java to open it a certain way? Thanks in advance.

  • parsing raw email in php

    - by Uberfuzzy
    i'm looking for good/working/simple to use php code for parsing raw email into parts. i've written a couple of brute force solutions, but everytime, one small change/header/space/something comes along and my whole parser fails and the project falls apart. and before i get pointed at PEAR/PECL, i need actual code. my host has some screwy config or something, i can never seem to get the .so's to build right. if i do get the .so made, some difference in path/environment/php.ini doesnt always make it available (apache vs cron vs cli) oh, and one last thing, i'm parsing the raw email text, NOT pop3, and NOT imap. its being piped into the php script via a .qmail email redirect. i'm not expecting SOF to write it for me, i'm looking for some tips/starting points on doing it "right". this is one of those "wheel" problems that i know has already been solved.

  • file descriptors and open files

    - by amanda
    Hello, I have two quick questions: When do two file descriptors point to the same open file ? When do two open files point to the same inode ? Also, if you happen to have some good documentation with graphs explaining this, i'll be very grateful if you show me the link to it :) Thanks!

What I'm wondering if I should have any more files for ... well, you tell me. Any help would be appreciated.

  • HTML File upload field style

    - by Steven1350
    I am trying to create a file upload field that has a little bit of style to it, but I seem to be having problems finding examples of this. I know part of the reason is that the field itself varies from browser to browser. Any ideas how to do this? Or is there a way to do this without using a file element of a form that can be styled?

  • Creating and writing file from a FileOutputStream in Java

    - by Althane
    Okay, so I'm working on a project where I use a Java program to initiate a socket connection between two classes (a FileSender and FileReceiver). My basic idea was that the FileSender would look like this: try { writer = new DataOutputStream(connect.getOutputStream()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } //While we have bytes to send while(filein.available() >0){ //We write them out to our buffer writer.write(filein.read(outBuffer)); writer.flush(); } //Then close our filein filein.close(); //And then our socket; connect.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); The constructor contains code that checks to see if the file exists, and that the socket is connected, and so on. Inside my FileReader is this though: input = recvSocket.accept(); BufferedReader br = new BufferedReader(new InputStreamReader(input.getInputStream())); FileOutputStream fOut= new FileOutputStream(filename); String line = br.readLine(); while(line != null){ fOut.write(line.getBytes()); fOut.flush(); line = br.readLine(); } System.out.println("Before RECV close statements"); fOut.close(); input.close(); recvSocket.close(); System.out.println("After RECV clsoe statements"); All inside a try-catch block. So, what I'm trying to do is have the FileSender reading in the file, converting to bytes, sending and flushing it out. FileReceiver, then reads in the bytes, writes to the fileOut, flushes, and continues waiting for more. I make sure to close all the things that I open, so... here comes the weird part. When I try and open the created text file in Eclipse, it tells me "An SWT error has occured ... recommended to exit the workbench... see .log for more details.". Another window pops up saying "Unhandled event loop exception, (no more handles)". However, if I try to open the sent text file in notepad2, I get ThisIsASentTextfile Which is good (well, minus the fact that there should be line breaks, but I'm working on that...). Does anyone know why this is happening? And while we're checking, how to add the line breaks? (And is this a particularly bad way to transfer files over java without getting some other libraries?)

  • Is there a lightweight multipart/form-data parser in C or C++?

    - by Hongli
    I'm looking at integrating multipart form-data parsing in a web server module so that I can relieve backend web applications (often written in dynamic languages) from parsing the multipart data themselves. The multipart grammar (RFC 2046) looks non-trivial and if I implement it by hand a lot of things can go wrong. Is there already a good, lightweight multipart/form-data parser written in C or C++? I'm looking for one with no external dependencies other than the C or C++ standard library. I don't need email attachment handling or buffered I/O classes or a portability runtime or whatever, just multipart/form-data parsing. Things that I've considered: GMime - depends on glib, so no go. libapreq - too large, depends on APR, badly documented, no unit tests. I've also looked at writing a parser with Ragel, but I can't figure out how to do it because the grammar is not static: the boundary can change arbitrarily.

  • What is the simplest way to download file in PHP

    - by silent
    Hi all, I need to download an image from some URL to my server. However, my server's config disallowed me to do it this way: getimagesize( $file ); Because, it generate error: Warning: getimagesize() [function.getimagesize]: URL file-access is disabled in the server configuration in somefile.php on line 10 So, is there another way I can use that doesn't require external library?

  • Large File Download - Connection With Server Reset

    - by daveywc
    I have an asp.net website that allows the user to download largish files - 30mb to about 60mb. Sometimes the download works fine but often it fails at some varying point before the download finishes with the message saying that the connection with the server was reset. Originally I was simply using Server.TransmitFile but after reading up a bit I am now using the code posted below. I am also setting the Server.ScriptTimeout value to 3600 in the Page_Init event. private void DownloadFile(string fname, bool forceDownload) { string path = MapPath(fname); string name = Path.GetFileName(path); string ext = Path.GetExtension(path); string type = ""; // set known types based on file extension if (ext != null) { switch (ext.ToLower()) { case ".mp3": type = "audio/mpeg"; break; case ".htm": case ".html": type = "text/HTML"; break; case ".txt": type = "text/plain"; break; case ".doc": case ".rtf": type = "Application/msword"; break; } } if (forceDownload) { Response.AppendHeader("content-disposition", "attachment; filename=" + name.Replace(" ", "_")); } if (type != "") { Response.ContentType = type; } else { Response.ContentType = "application/x-msdownload"; } System.IO.Stream iStream = null; // Buffer to read 10K bytes in chunk: byte[] buffer = new Byte[10000]; // Length of the file: int length; // Total bytes to read: long dataToRead; try { // Open the file. iStream = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read); // Total bytes to read: dataToRead = iStream.Length; //Response.ContentType = "application/octet-stream"; //Response.AddHeader("Content-Disposition", "attachment; filename=" + filename); // Read the bytes. while (dataToRead > 0) { // Verify that the client is connected. if (Response.IsClientConnected) { // Read the data in buffer. length = iStream.Read(buffer, 0, 10000); // Write the data to the current output stream. Response.OutputStream.Write(buffer, 0, length); // Flush the data to the HTML output. Response.Flush(); buffer = new Byte[10000]; dataToRead = dataToRead - length; } else { //prevent infinite loop if user disconnects dataToRead = -1; } } } catch (Exception ex) { // Trap the error, if any. Response.Write("Error : " + ex.Message); } finally { if (iStream != null) { //Close the file. iStream.Close(); } Response.Close(); } }
