Return data read from the server.
object.Read( Buffer, [Length] )
- A buffer that the data will be stored in. If the variable is a
String then the data will be returned as a string of characters.
This is the most appropriate data type to use if the server is
sending data that consists of printable characters. If the server
is sending binary data, it is recommended that a Byte array be
- A numeric value which specifies the number of bytes to read.
Its maximum value is 231-1 = 2147483647. This parameter
is required to be present for string data. If a value is specified
for this parameter for other permissible types of data, and it is
less than number of bytes that is determined by the control, then
Length will override the internally computed value. If the
parameter is omitted, then the maximum number of bytes to read is
determined by the size of the buffer.
The number of bytes actually read from the server is returned by
this method. If an error occurs, a value of -1 is returned.
The Read method returns data that has been read from the
server, up to the number of bytes specified. If no data is
available to be read, an error will be generated if the control is
non-blocking mode. If the control is in blocking mode, the program
will stop until data is returned by the server or the connection is
closed. Note that it is possible for the returned data to contain
embedded null characters.
