WNetAddConnection info  Overview  Group

The WNetAddConnection function enables the calling application to connect a local device to a network resource. A successful connection is persistent, meaning that Windows automatically restores the connection during subsequent logon operations.

This function is provided for compatibility with earlier versions of Microsoft Windows. For new applications, use the WNetAddConnection2 function.

DWORD WNetAddConnection(

LPTSTR lpRemoteName,	// pointer to network device name
LPTSTR lpPassword,	// pointer to password
LPTSTR lpLocalName	// pointer to local device name
);

Parameters

lpRemoteName

Points to a null-terminated string that specifies the network resource to connect to.

lpPassword

Points to a null-terminated string that specifies the password to be used to make a connection. This parameter is usually the password associated with the current user.

If this parameter is NULL, the default password is used. If the string is empty, no password is used.

lpLocalName

Points to a null-terminated string that specifies the name of a local device to be redirected, such as F: or LPT1. The case of the characters in the string is not important. If the string is NULL, a connection to the network resource is made without redirecting the local device.

Return Values

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is an error code. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:

Value	Meaning
ERROR_ACCESS_DENIED	Access is denied.
ERROR_ALREADY_ASSIGNED	The device specified in the lpLocalName parameter is already connected.
ERROR_BAD_DEV_TYPE	The device type and the resource type do not match.
ERROR_BAD_DEVICE	The value specified in lpLocalName is invalid.
ERROR_BAD_NET_NAME	The value specified in the lpRemoteName parameter is not valid or cannot be located.
ERROR_BAD_PROFILE	The user profile is in an incorrect format.
ERROR_CANNOT_OPEN_PROFILE	The system is unable to open the user profile to process persistent connections.
ERROR_DEVICE_ALREADY_REMEMBERED	An entry for the device specified in lpLocalName is already in the user profile.
ERROR_EXTENDED_ERROR	A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
ERROR_INVALID_PASSWORD	The specified password is invalid.
ERROR_NO_NET_OR_BAD_PATH	The operation cannot be performed because either a network component is not started or the specified name cannot be used.
ERROR_NO_NETWORK	The network is not present.

The function returns error codes and sets the error code values returned by GetLastError.
