LInetHttp::Connect

#include "ltwrappr.h"

L_INT LInetHttp::Connect(pszServer, pszUserName = NULL, pszPassword = NULL, nPort = 80)

L_TCHAR *pszServer;	/* name of server to connect to */
L_TCHAR *pszUserName;	/* username for authentication */
L_TCHAR *pszPassword;	/* password for authentication */
L_INT nPort;	/* port number to connect to */

Connects to an HTTP server.

Parameter	Description
pszServer	Character string that contains the name of the server to which to connect. The name can be a network name, an IP address, or a domain name (www.leadtools.com).
pszUserName	Character string that contains the name of the user logging on. Default value is NULL. This is a NULL-terminated string.
pszPassword	Character string that contains the password to use when logging on. If both pszPassword and pszUsername are NULL, the connection is made anonymously.
nPort	Number of the port to which to connect. The default port assignment for web servers is 80.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Use this function to establish a connection with an HTTP Server. To connect anonymously pass NULL for pszUserName and pszPassword.

A connection to an HTTP server must be established before using any other HTTP functions. If a connection is disconnected, via either LInetHttp::Disconnect or LInetHttp::~LInetHttp, then a connection must be re-established before any other HTTP functions are called. LInetHttp::Connect and LInetHttp::LInetHttp can be used to establish a connection with an HTTP server.
