CDaoDatabase: how to know if value of a field is empty?
Posted on 2000-02-26
in a .mdb database, the value of a field may be empty, that is , nothing in that field (actually, since the database initially is not created by me, so i dunno whether it is " " or just leave it empty there). is there any way to check whether it is empty?
i had use
to get the value .. however if i use strcmp(s1," ")==0) to check. it gives error....
pls help me!!! thanks a lot!
