How would I go about reading a file from a UNC path, discovering the proper MIME type, and streaming that out to a browser? It feels to me like I'm re-inventing IIS, and I'll also have to maintain my own MIME type database for each file extension. Does the above request sound reasonable, or is there a better way? I plan on streaming t...
Currently I'm using the below code to allow a user to download a file that's attached to a couchdb document. I'm using couchdbkit with Django. def get_file(request, user_id): user = User.objects.get(pk = user_id) application = user.get_profile().application() attachment_name = request.GET.get('name', None) assert attachm...
Update: After looking in the event log at around the time this occurred, I get the message: "The server was unable to allocate from the system nonpaged pool because the pool was empty." repeated continually throughout the log, until it was rebooted. I am writing a class that writes debugging information to a file, up until now the class...
I am a little confused as to the steps of reading a file into buffer gradually. from the MSDN docs public abstract int Read( byte[] buffer, int offset, int count ) source from C# Examples FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read); try { int length = (int)fileStream.Length; // ...
So I'm trying to compile an Asteroids game. It's almost working, all the files are in place etc etc... The issue comes when it hits this code. FileStream myFileStream = new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read); string myTempFile = @"F:\Documents\Junior School\Computer Programming (Java 1)\AsteroidsWithSo...
Hi, I'd like to open a text file and not allow any other processes to write to it. I understand I can do this with the following FileStream: Dim fs As New FileStream(_FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read) Once I have access like this I need to read all of the lines (I will use a StreamReader(fs)) and then I w...
I've written the following program which purpose is to create a file of a give size with some random data in it. The program works fine and does what it's suppose to do. However, I don't understand why it consumes 5GB of RAM (see screenshot of my Task Manager). While I am writing the file with random data, I am not creating new objects. ...
The default implementation on Stream creates a new single-byte array and then calls Read. While this is formally correct, it is inefficient. Any stream with an internal buffer should override this method and provide a much more efficient version that reads the buffer directly, avoiding the extra array allocation on every call. ...
Hi all, I'm using a FileStream to download information of an FTP server to a directory on my C:\ drive. For some reason, even though I've even tried setting the directory permissions to even 'Everyone' access, it's given me this exception: System.UnauthorizedAccessException: Access to the path 'C:\tmpfolder' is denied' Why is this?...
Is it possible to save a file's original create / modify dates when saving a file to a db (via filestream & BinaryReader) and then have those dates attached to the file when recreating the file, again via filestream & BinaryWriter, from the db? If possible, how do I do it? My inital research leads me to believe only the file contents ar...
I have some code that inserts data into some tables (one table has a FILESTREAM column) and then calls SubmitChanges after it is done. db.Log = new System.IO.StreamWriter(@"c:\windows\temp\linq.log") { AutoFlush = true }; db.SubmitChanges(ConflictMode.FailOnFirstConflict); I have referenced the following links but they appear to not b...
