Passing NULLS in structure fields via CORBA

[Pacifica]

Heard it can't be done. What are the alternatives? Passing constant strings?

You can not do it because you will get a MARSHAL error. You can pass some additional flags what that structures are null, but you must pass valid pointers.

So I have to set the value of every field in a structure. I would need to define some type of constant I guess and have both the client and server agree to this value to mean NULL or value unchanged.

yes

If I got you right you have some CORBA struct that contains strings.
If this is true, you don't need to initialize these strings since they are initialized automatically to empty strings (i.e.: "&quot. Member strings are of type String_mgr.

Hi sog12,
if a string == "" this does not mean what it is a null string. null means nothing but "" means something. Haev you got this?
