I looked at some automation server samples in MSDN lib, such as mfccalc, but couldn't figure out how to recreate them from scratch. The source codes are thin and may have been created using little of AppWizard. One sample use both compiler com support (means manually editing these *.odl, *.cpp, *.h files or what?) and MFC (I don't see any *proxy.* files) to create these server/client pairs. Can someone help me? BTW, I use visual studio 6.0. Thanks
