QSOCKET Component

QSocket provides an easy to use interface to communicate between server/client with sockets.

QSocket Properties

Field	Type	R/W	Default	Support

Family	INTEGER	RW	AF_INET	W
	Family specifies the address family.
LParam	INTEGER	RW	FD_CONNECT	W
	LParam specifies the message to capture when you set WMessage and handle the message processing by assigning a new WndProc to your form.
MySocket	INTEGER	R		WXG
	MySocket stores the result of operations such as Open. So instead of using the return value of Open, you can use the property MySocket.
Parent	QFORM	W		W
Protocol	INTEGER	RW	IPPROTO_IP	W
Tag	INTEGER	RW		WXG
Transferred	INTEGER	R		WXG
Type	INTEGER	RW	SOCK_STREAM	W
WMessage	INTEGER	RW	0	W
	WMessage specifies a user defined message to be passed to your form for non-blocking calls, ie. Connecting.
