------- Additional Comments From rob@codeweavers.com 2006-28-06 19:53 ------- This is a bug in oleaut32. I changed the handling of IDispatch methods for typelibs to use the MIDL-generated code. The client attempts to connect to the IDispatch interface on the server-side. However, the server-side of things doesn't tell the RPC to expose the IDispatch interface, so the binding request is refused.
I'm not sure about the best way to fix this bug.
