Due to major architectural changes in the OLE communication layer, 16-bit applications that require remoting of custom interfaces are not supported at this time. However, 16-bit applications that use custom interfaces to an inprocess server should still function correctly. The following combinations of interoperability using custom interfaces are supported:
The following combinations of interoperability using custom interfaces are not supported:
Programmers who have written applications that provide custom interfaces must rewrite the custom interface marshalling code to conform to the RPC-based communication layer. However, information about writing a 16-bit custom-marshalling library is not available at this time. For more information about RPC, see the RPC Programmer's Guide and Reference.
