I'm learning A4D by modifying the code in the A4D demo. My app was
designed to feed a lot of arrays into listboxes, so I'd like to use
the rowset.newfromarrays library to display my data.
I declare the arrays (global at the moment), pass the array from 4D
to A4D, and then try to use the rowset command. All goes fine until
the rowset command and then an error is thrown from the method
"_arrayInit" in the rowset library:
"$_size:=size of array(=My_Array
Expecting a field or a variable"
It seems unlikely this is a bug in the method. Can anyone point me
to what I'm doing wrong?
My code follows... excuse the awkward array names. They make sense
in the world of ListBoxes.
Thanks in advance.
