There are two ways to read & write files 1.

It is basically used to start reading after preserving the characters in an array. At that point, the underlying streams pointer is out of sync with this streams position. read (byte b, int off, int len) method of BufferedInputStream class in Java is used to read bytes from the byte-input stream into the specified byte array which starts at the offset given by user. When bufStream is closed, netStream is in turn // Reading is done in blocks, but someone could read 1 byte from the buffer then write. NetworkTime = (DateTime::Now - startTime).TotalSeconds Ĭonsole::WriteLine( " seeking.\n""" Static void ReceiveData( Stream^ netStream, Stream^ bufStream )Īrray^receivedData = gcnew array(dataArraySize) Ĭonsole::WriteLine( "Receiving data using NetworkStream." ) Ä«ytesReceived += netStream->Read( receivedData, 0, receivedData->Length ) Static const int streamBufferSize = 1000 For example: List lines breader.lines ().collect (Collectors. Save the result of lines () to a List, so that you're then not reading from the file at all the second time.The first example shows the code that runs on the client, and the second example shows the code that runs on the server.Ä®xample 1: Code that runs on the client #using Two options: Reopen the file and read it from scratch. Vary the dataArraySize and streamBufferSize constants to view their effect on performance. DVRs must work with MJPEG, JPEG, H264 or MPEG-4 streams and stream video through http or rtsp. Video capture cards and the like must use DirectShow/WDM drivers and have 1 chip per channel. ![]() ![]() Specify the remote computer name as a command-line argument when starting the client. Analogue cameras: Xeoma supports analog cameras connected through capture cards, TV tuners, DVRs, USB dongles, etc. Start the server on a remote computer before starting the client. The following code examples show how to use the BufferedStream class over the NetworkStream class to increase the performance of certain I/O operations.
