Class wwSocket

Remarks

IMPORTANT: You can only run one socket instance per FoxPro application!!! If you connect a second socket you will kill any previous existing socket connections created with this class.

Requires Winsock 2.0 on the client machine. (ws2_32.dll in your SYSTEM32/SYSTEM dir).

Class Members

Member		Description
	connect	Connects to a socket on a server. o.connect(lcServer, lnPort)
	disconnect	Disconnects from a socket on the server. o.disconnect()
	receive	Receives data from a socket. To receive large amounts of data you will have to use Receive() in a loop until you've received the expected content size. There's no way to know when content is… o.receive(lnSize)
	WaitFor	Receives data until either the provided string is found or the request times out based on the nTimeout property setting. This method is very useful for long data streams that usually would require… o.WaitFor(lcSearchString,lnSize)
	WaitForSize	Reads a socket until the specified number of bytes are received. o.WaitForSize(lnBytes)
	send	Sends data to a socket on the server. o.send(lcInput)
	GetLog	Returns the content of the log captured when lLogSession is .T. o.GetLog()
	Listen	Puts a socket into server mode to listen for incoming connections on a given port. If a connection is made the socket is opened for reading and writing using the regular Send/Receive etc. methods.… o.Listen(lnPort,lnTimeOut)
	sendreceive	Sends a string to the open socket, waits for a response and returns the string response. You should use SendReceive only on short requests that you know will retrieve typical single line responses… o.sendreceive(lcInput,lnSize)
	socketsend	High level method that connects to a socket, sends data and receives a result then disconnects from the socket. Great for various XML services that follow a simple transaction model with a 'hit'. o.socketsend(lcInput,lcServer,lnServerPort,lnTimeout,@lcError)
	cerrormsg	Error Message if an error occurred.
	nBufferSize	The default Receive buffer size in bytes. This size is used to determine how much data the socket waits for at a time before returning control to you. Note that this doesn't guarantee that the…
	nLastReadSize	The size of the data returned on the last Receive() method call. Use this if you're reading binary data that might contain NULLS and might not fill the buffer fully.
	lLogSession	Allows you to log the entire TCP/IP session and retrieve the log via the GetLog() method.
	lstripnulls	Strips CHR(0) NULLS from the received buffer. Otherwise the full buffer will be passed back which is padded with CHR(0)'s.
	nerror	Error Number
	ntimeout	Socket timeout, in seconds, used to determine when an operation fails due to an idle timeout of no data sent or received. Default: 10 (seconds)
