how to realize the function of "adreadproxydatastring" in c++?
adreadproxydatastring
summary
short adreadproxydatastring (char *a);
description
reads a proxy (object or entity) string into the buffer pointed to by a.
return value
returns 1 on success, 0 on failure. on failure, aderror() should be checked for an indication of the cause of the failure.
given the pointer to a acdbproxyentity object, how can i get the value of its string atrributes, like the function of "adreadproxydatastring" in c.
thanks!!!!
to get access to proxy entity (object) data you need to know its data format and implement your custom class representing the entity.

read binary data from proxy
n our application i need to read binary data from oddbproxyentity, so that it can be stored in our database (not oda database), and so that we can later write it our to dwg/dxf.
(in other words, we don't want to handle proxy entity, just store it's data for round-trip back to dwg/dxf).
i don't see how i can use custom entity class as in excustobjs to do what i want.
is there any other way i can extract binary data from oddbproxyentity after it has been loaded form file?
thanks
you can use oddbentget() / oddbentmod() for that purpose (see the bottom of dbobject.h)
