I'm reading a .gz file from some slow source (like FTP Server) and am processing the received data right away. Looks something like this: FtpWebResponse response = ftpclientRequest.GetResponse() as FtpWebResponse; using (Stream ftpStream = response.GetResponseStream()) using (GZipStream unzipped = new GZipStream(ftpStream, CompressionMo...
How do I read / write gzipped files in C++? The iostream wrapper classes here look good, and here is a simple usage example: gz::igzstream in(filename); std::string line; while(std::getline(in, line)){ std::cout << line << std::endl; } But I wasn't able to actually link it (although I have a /usr/lib/libz.a). A simple g++ test-gzs...
I'm trying to decompress a GZipStream. The problem is that the "Length" property on the stream throws a "NotSupported" exception. How do I know what size to make my buffer when I'm reading the bytes from the stream? Since it's compressed I don't know how large the uncompressed version will be. Any suggestions? ...
Hello Folks, I have a file in .gz format. The java class for reading this file is GZIPInputStream. However, this class doesn't extend the BufferedReader class of java. As a result, I am not able to read the file line by line. I need something like this reader = new MyGZInputStream( some constructor of GZInputStream) reader.readLine...
I have a large amount of data (~100k) that my C# app is sending to my Apache server with mod_gzip installed. I'm attempting to gzip the data first using System.IO.Compression.GZipStream. PHP receives the raw gzipped data, so Apache is not uncompressing it as I would expect. Am I missing something? System.Net.WebRequest req = WebRequest....
Hi all, I have a server that basically caters to multiple clients. I am basically using gzip(input/output)stream to compress the data between client-server. Many clients can send the requests to server at the same time and hence i have a thread to cater to each client. Now, the problem tat i am experiencing is that "randomly" some cli...

I have a .NET 2.0 WinForms app that connects to a backend WAS server. I am using GZipStream to decode data coming back from a HttpWebRequest call made to the server. The data returned is compressed CSV, which Apache is compressing. The entire server stack is Hibernate-->EJB-->Spring-->Apache. For small responses, the performance is f...
I have code that should do the compression: FileStream fs = new FileStream("g:\\gj.txt", FileMode.Open); FileStream fd = new FileStream("g:\\gj.zip", FileMode.Create); GZipStream csStream = new GZipStream(fd, CompressionMode.Compress); byte[] compressedBuffer = new byte[500]; int offset = 0; ...
What is wrong with this code below. I always get FALSE, meaning after compression, decompressed data does not match original value. public static bool Test() { string sample = "This is a compression test of microsoft .net gzip compression method and decompression methods"; System.Text.ASCIIEncoding encodi...
Hi All- I'm reading a file(a flash swf) from .Net 3.5 that has a header which states whether the body of the file/Stream is compressed or not. However, I'm having problems-after I rewrap the basic File stream in a GZipStream, I get an exception stating that "The magic number in GZip header is not correct. Make sure you are passing in a...

Hi folks, Does anyone know how to get access to request HTTP headers within MessageEncoder.ReadMessage method? It seems that WCF already "knows" request headers at the point of invoking ReadMessage method, at least Content-Type and Content-Length but I cannot get the access to the Content-Encoding header. Basically, I'm trying to utili...
