Hello,



I have two questions concerning CoreLibrary. I am looking forward the
answer, if someone knows, I would be grateful.





1.

There is server on localhost that accepts connections on port 10000 run.

I want to create client that will connect to this port and send
Message using NetworkConnection class. I have following lines:



           NetworkConnection* con =3D new
NetworkConnection("localhost", 10000, new NetMessageProtocol(), NULL);





           if (!con->isConnected()){

                       printf("Connection is not connected\n");

                       return false;



           }







           Message* msg =3D new Message("from", "to", "Hey!");

           Message* returnMsg =3D con->sendReceiveObject(msg, 1500);

           printf("Main received message:\n  %s\n\n", (char
*)returnMsg->print());

           delete(returnMsg);



Why server accepts Message only if I connect my computer to network
(LAN or modem connection)? As server is run on localhost, there is no
need to do it. Is there any solution for this?



2.

There are two classes, class A and class B, declared in different
headers (A.h and B.h). These headers include same headers from
CoreLibrary (i.e. JString.h, JTime.h ). When I declare another class,
class C in header C.h that includes both A.h and B.h  I got errors in
VC98 folder:



c:\program files\microsoft visual studio\vc98\include\new(35) : error
C2059: syntax error : 'constant'

c:\program files\microsoft visual studio\vc98\include\new(35) : error
C2091: function returns function

c:\program files\microsoft visual studio\vc98\include\new(35) : error
C2809: 'operator new' has no formal parameters

c:\program files\microsoft visual studio\vc98\include\new(36) : error
C2059: syntax error : 'constant'

c:\program files\microsoft visual studio\vc98\include\new(37) : error
C2091: function returns function=85=85=85=85.



How I can avoid this errors? Do I have to change some properties in
Project workspace? (in also tried to make project using same
properties as your TestProject, but I got same mistakes)

Sashka
