Hi
I got a access violation on 0x00000000 with the class DDD but I cannot
figure
out what's wrong
When the symbol NO_EXCEPTION is defined, the member acccode is set to an
instance of ACCCODE and the serialization is working fine. But when this
symbol is undefined, one gets the exception.
I am suspecting the input serialization to bypass the loading of the member
FIELD* field (which is following the "acccode" member)
which leads to an exception when the next member DISP* disp is loaded
but I have no way to check it out
any idea??
