    This package depends on both BLT and LMOBJ.

    NAME:	DOMAIN_COMBO

    SYNOPSIS:	combo box with additional logic for containing domains

    INTERFACE:	DOMAIN_COMBO()		constructor; initializes the
					combo's list with the specified
					domains

    PARENT:	COMBOBOX

    CAVEATS:
	See the COMBOBOX header for a note about the cbMaxLen
	parameter to the constructor.

	This class currently has no means of appearing in an APP_WINDOW.

    NOTES:
	CODEWORK.  While it would be nice if the cbMaxLen parameter to the
	constructor could default to DNLEN, BLT does not otherwise require
	netcons.h.  If netcons.h moves into lmui.hxx in the future, this
	default value may be a good idea.

    NAME:	DEVICE_COMBO

    SYNOPSIS:	combo box with added logic for containing device names

    INTERFACE:	DEVICE_COMBO()		constructor
		Refresh()		clears the listbox, and then
					fills it with fresh information;
					preserves the selection, if
					possible (otherwise, uses no
					selection)
		QueryDevice()		convenient way to get the
					device name string of the currently
					selected item (returns empty
					string if no item is selected)
		DeleteCurrentDeviceName()
					deletes the currently selected
					item; does nothing if there is
					no selection
