I have some data that I am serializing. I need to save and restore this from a VarBinary column using ADO.NET (also using Enterprise Library) under .Net 3.5 (not 4.0 yet). The only interface I seem to be able to find and get working is by using a byte[]. This requires allocating a large array to do the transfer. It seems impossible t...
I have a little problem with a C library: Byte Flood Cryptography. ( http://bfcrypt.sourceforge.net ). I would create a program which use both linux sockets and Byte Flood Cryptography (the Byte Flood Cryptography functions are near from those provided from stdio.h, and this, I have understand). I don't know how to 'bind' the two s...
Hi All, I've been having some trouble with computeHash. I'm using both computeHash(Stream) and computeHash(byte[]). For some reason, they are giving back different result. I've tried writing the byte[] into a MemStream but result was the same when using Byte[] FileStream zz = new FileStream(t.Filename, FileMode.Open, FileAccess.Read);...
What is the best solution in C# for computing an "on the fly" md5 like hash of a stream of unknown length? Specifically, I want to compute a hash from data received over the network. I know I am done receiving data when the sender terminates the connection, so I don't know the length in advance. [EDIT] - Right now I am using md5, but th...
Hey all, I have a state machine design that needs to support playback. We have states that perform actions and sometimes need to generate random numbers. In case the program shuts down while in the middle of the FSM's execution, the program needs to playback the whole FSM using the same random numbers as before. For a basic example, le...

I have a generic handler in vb.net that builds a chart and then returns a png as a result. Relevant code on /GetChart.ashx (which is actually called as /GetChart.ashx?report=1): AssetChart.RenderType = RenderType.BinaryStreaming Dim mstream As New MemoryStream() AssetChart.SaveImage(mstream, ChartImageFormat.Png) Dim byteArray As Byte...
I have a single key encrypted HTTP Live Stream which decodes fine in Quicktime and iPhone. I'm trying to create a simple client application to do the decryption of the ts files. Right now I've used openssl to decrypt. I believe I have the correct arguments to openssl and I'm inserting the key and the IV properly. I can successfully d...
I am using a CryptoStream for writing encrypted audio data to the file (underlying stream is FileStream). When I try to call CryptoStream.Close() over the full disk, I get an exception. I know that this is because CryptoStream.Close() invokes FlushFinalBlock() during disposing. As a result I get the corrupted data in my encrypted file an...
I have written a program that connects to a server on a given IP using the NSStream protocol outlined in Apple's stream programming guide. The connection and transfer of data works flawlessly, however if the user specifies the wrong IP and the program attempts to open the streams it results in the program becoming unresponsive. From wha...

I am using the following code to stream an image source: BitmapImage Art3 = new BitmapImage(); using (FileStream stream = File.OpenRead("c:\\temp\\Album.jpg")) { Art3.BeginInit(); Art3.StreamSource = stream; Art3.EndInit(); } artwork.Source = Art3; "artwork" i...
I would like to chain multiple stream operations (like downloading a file, uncompressing it on the fly, and processing the data without any temp files). The files are in 7z format. There is a LZMA SDK available, but forces me to create an outside output stream instead of being a stream itself - in other words the output stream will have ...
There is a lib that outputs its results into a given Stream object. I would like to begin consuming the results before the lib is done. The Stream should be blocking to simplify usage and avoid excessive memory consumption if producer runs ahead too far; thread safe to allow independent existence of producer and consumer. Once the lib f...
Hi, I had some time and decided to implement a one time pad just for fun and self education. Now I end up with a weird behavior of the data. Its driving me crazy ^^. Would you please help me?
