I have a concatenated file made up of some number of bzip2 archives. I also know the sizes of the individual bzip2 chunks in that file. I would like to decompress a bzip2 stream from an individual bzip2 data chunk, and write the output to standard output. First I use fseek to move the file cursor to the desired archive byte, and then ...

The data rate is between 0.5MB - 10MB / sec, depending on the external hardware configuration. The reading of the external devices is currently being done on a BackgroundWorker. Trying to write the acquired data to disk with...

Quite embarassing issue, though i come from web development and rarely have to deal with files i/o. I wrote a simple config updater for use on my shared hosting. It scans the directory for subdirectories, and then writes config lines to a file - one line for each subdirectory. The problem is, when it detects there are config lines but n...

I use Invoke to make the call because the call comes from a Thread and the function has to put the results on a Form. The function accepts any kind of Stream (I call it with MemoryStreams too without a problem) ...

Hello there so I just setup this basic poll, I inspired myself from something I found out there, and it's just a basic ajax poll that waves the results in a text file. Although I was wondering, since I do not want the user to simply mass-click to advantage / disadvantage the results, i thought about adding a new text file that could sim...
I attempted to create a sort-of file generator which spits out hardcoded messages to a file with slight alterations to some of the strings based on user input. Since I'm utilizaing polymorphism, I have multiple files and interfaces. I'm finding myself passing a file parameters more times than one and is starting to rethink the way I've...
I'm using the Jython 2.51 implementation of Python to write a script that repeatedly invokes another process via subprocess.Popen and uses PIPE to pipe stdout and stderr to the parent process and stdin to the child process. After several hundred loop iterations, I seem to run out of file descriptors. The Python subprocess documentati...
Current documentation here doesn't seem to mention any parameters governing the stream's behaviour with regards to whether file is re-created every time or just gets data appended. Is there a way to create a writeStream which appends the data? ...
