    	connect_localdrive: INTEGER_32 is 256

    			-- This flag instructs the system not to use any default settings

    			-- opportunity to supply an alternative. This flag is ignored
    			-- unless CONNECT_INTERACTIVE is also set.
    			--

    	connect_redirect: INTEGER_32 is 128
    			-- This flag forces the redirection of a local device when making
    			-- the connection.
    			--
    			-- If the lpLocalName member of NETRESOURCE specifies a local
    			-- device to redirect, this flag has no effect, because the

    			-- This flag instructs the operating system to store the network
    			-- resource connection.
    			--
    			-- If this bit flag is set, the operating system automatically

    			-- system remembers only successful connections that redirect
    			-- local devices. It does not remember connections that are
    			-- unsuccessful or deviceless connections. (A deviceless
    			-- connection occurs when lpLocalName is NULL or when it points
    			-- to an empty string.)
    			--
    			-- If this bit flag is clear, the operating system does not
    			-- automatically restore the connection at logon.

    			-- The attempt to make the connection was canceled by the user
    			-- through a dialog box from one of the network resource
    			-- providers, or by a called resource.

    	error_invalid_parameter: INTEGER_32 is 87
    			-- This error is a result of one of the following conditions:

    			--    is not NULL, but lpBufferSize is either NULL or points to
    			--    zero.
    			-- 2. The dwType member is neither RESOURCETYPE_DISK nor
    			--    RESOURCETYPE_PRINT. In addition, either CONNECT_REDIRECT
    			--    is set in dwFlags and lpLocalName is NULL, or the
    			--    connection is to a network that requires the redirecting
    			--    of a local device.

    	error_more_data: INTEGER_32 is 234
    			-- The lpAccessName buffer is too small.
    			-- If a local device is redirected, the buffer needs to be large
    			-- enough to contain the local device name. Otherwise, the
    			-- buffer needs to be large enough to contain either the string
