I am using this: byte[] buffer = new byte[10240]; As I understand this initialize the buffer array of 10kb filled with 0s. Whats the fastest way to fill this array (or initialize it) with junk data every time? I need to use that array like >5000 times and fill it every time with different junk data, that's why I am looking for a fas...
It is written byte[][] getImagesForFields(java.lang.String[] fieldnames) Gets an array of images for the given fields. On the other hand, as long as I use the method in the web application project built on asp.net 2.o using c#; the provided web method declared above, returns sbyte; Have a look my code below; formClearanceServic...
I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put t...
I would like to know whether using a BinaryReader on a MemoryStream created from a byte array (byte[]) would reduce performance significantly. There is binary data I want to read, and I get that data as an array of bytes. I am currently deciding between two approaches to read the data, and have to implement many reading methods accordin...
Hi, I've developed an application to capture and save images to a database, but I'm having an issue with memory usage. On my domain object I have 3 properties: Image - Byte array, contents are a jpg RealImageThumb - The byte array converted to a BitmapImage and shrunk, displayed to the user in a gridview with other thumbnails Real...
I have a byte array that I'm encoding to a string: Private Function GetKey() As String Dim ba() As Byte = {&H47, &H43, &H44, &H53, &H79, &H73, &H74, &H65, &H6D, _ &H73, &H89, &HA, &H1, &H32, &H31, &H36} Dim strReturn As String = Encoding.ASCII.GetString(ba) Return strReturn End Function Then I wri...
I am trying to send a byte[] from a client to a web service. The array is composed of a serialized XML file. My test scenario works (with a very small byte[]). Here is the code: FormsService.FormsServiceClient client = new FormsService.FormsServiceClient(); XmlDocument doc = new XmlDocument(); XmlElement root = doc.Crea...
When a path is specified as the source argument of a SWFLoader, arguments can be appended to the path so that the SWF runs with the desired arguments. <mx:SWFLoader id="mySwf" source="pathOfSwf.swf?arg1=1"/> How do you do the same thing when instead of a path you specify a ByteArray as the source argument of a SWFLoader. <mx:SWFLoade...
Hello, I have the following code to read data from a Stream (in this case, from a named pipe) and into a byte array: // NPSS is an instance of NamedPipeServerStream int BytesRead; byte[] StreamBuffer = new byte[BUFFER_SIZE]; // size defined elsewhere (less than total possible message size, though) MemoryStream MessageStream = new Memor...
Hi All, I'm doing a number of bitwise operations on an array of bytes in C#. I'm obtaining the array by calling FileStream.Read. I just realized that I'm not sure what would happen if a file had a bad byte or corrupt byte in it somewhere. For example, maybe a nibble is chopped off of the end or something like that. What would the Fi...

Hey. I'm converting a 2.6.5 application to python 3.1. I'm trying to convert a byte order received through socket.recv() into a string, by doing the following: str(temp, 'UTF-8', 'ignore') The problem is unknown characters are removed ("ignored"), such as \x00 and \xff (WebSockets characters), I do want to convert the byte order to a ...
How should I really go about implementing the following? I will have to handle a byte array that will contain text on several lines. The average size of the data is probably going to be around 10 kilobytes of data. After unspecified amount of lines there will be a line starting with special token ("FIRSTSTRING"). Later somewhere on the...
