The component will be blind to the table(s) of the host.
So, the solution that I think (i haven't coded this part yet) will work is:
(Component Method)
// Export_All
//$1 - pointer - to a pointer array where each element
// of the array points to a Host table to be exported
//$2 - text - export format (tab, csv, xml, 4D record etc)
//RETURNS - text - error message(s) if failure
From this I can specify the table(s) to be exported in the host, 1 or all or
somewhere between, and I get a general export system rather then all or nothing.
