'----------------------------------------------
'WNetAddConnection2

'Allows the caller to redirect (connect) a local
'device to a network resource. It is similar to
'WNetAddConnection, except that it takes a pointer
'to a NETRESOURCE structure to describe the network
'resource to connect to. It also takes the addition
'parameters lpUserID and dwFlags.

'lpNetResource
'Specifies the network resource to connect to.
'The following fields must be set when making a
'connection, the others are ignored.

' lpRemoteName: Specifies the network resource
' to connect to. This is limited
' to MAX_PATH.

' lpLocalName: This specifies the name of a local
' device to be redirected, such as "F:"
' or "LPT1". The string is treated in a
' case insensitive manner, and may be
' the empty string (or NULL) in which
' case a connection to the network resource
' is made without making a redirection.

' lpProvider: Specifies the NP to connect to. If NULL
' or empty string, Windows will try each
' NP in turn. The caller should set
' lpProvider only if it knows for sure
' which network it wants. Otherwise, it
' is preferable to let Windows determine
' which NP the network name maps to.
' If this is non NULL, Windows will try
' the named NP and no other.

' dwType: Specifies the type of resource to connect to.
' It must be RESOURCETYPE_DISK or RESOURCETYPE_PRINT
' if lpLocalName is not the empty string. It may
' also be RESOURCETYPE_ANY if lpLocalName is the
' empty string.

'lpPassword
'Specifies the password to be used in making the
'connection, normally the password associated with
'lpUserID. A NULL value or string may be passed in
'to indicate to the function to use the current
'default password.
'
'lpUserID
'This specifies the identity of the user needed to
'make the connection. If NULL, a default will be
'applied. This is used when the user wishes to connect
'to a resource, but has a different user name or
'account assigned to him for that resource. This
'identification represents a security context, and
'is NP specific.
'
'dwFlags
'This is a bit mask which may have any of the
'following bits set:
'
' CONNECT_UPDATE_PROFILE: If the connection should
' be made persistent. If set,
' Windows automatically restores
' this connection when the user
' logs on to the network. A connection
' is only made persistent if the
' connection was successful.
