Class
CUG_HTML_DataSource
Purpose
This is a derived grid datasource, that
allows HTML tables to be loaded into the
standard grid memory manager.
While this data source only handles
importing simple HTML tables , it will
skip over embedded tables to completely
import the table. You can decided which
of the outer most tables to import by
passing a table number to the Open
function.
Details
-This class derives from CUGMem which is
the standard memory manager.
-The Load method has been implemented.
-Standard return values for functions are:
UG_SUCCESS - success (0)
UG_NA - not available (-1)
1 and up - error codes
