Hi,

I am trying to call a method found in an application server. According to
the documentation, this will do:

IMyAppServerDisp TempInterface(LPDISPATCH(MyConnection->AppServer));
TempInterface->SpecialMethod(x,y);

This does not compile!

I've changed it to:

IMyAppServerDisp TempInterface((IMyAppServer
*)LPDISPATCH(MyConnection->AppServer));
TempInterface->SpecialMethod(x,y);

And it compiles but throws a Priviledge violation exception when executed.
What am I doing wrong?

Thanks.

PS: Reply to ame@dcdmc.intnet.mu please

Avinash,

I found out through tech support that the documentation on this is
incorrect and was given the proper technique, which I have turned into a
macro:

#define APPSERVER_INTERFACE( CONNECTION, SERVERNAME, VAR ) \
  IDispatch * VAR##Disp = (IDispatch *)(CONNECTION->AppServer); \
  I##SERVERNAME * VAR##Intf = reinterpret_cast<I##SERVERNAME
*>(VAR##Disp); \
  I##SERVERNAME##Disp VAR( VAR##Intf );

In the context of the documentation example, you would instead declare

APPSERVER_INTERFACE( MyConnection, MyAppServer, TempInterface );

Happy Coding,
Steve Pietrykoski
