If you have written your COM EXE Server using atl, then to register the exe you do mycomserver.exe /RegServer regsvr32 is just for DLL's. There should be no problem in calling a DLL COM server from a COM server EXE. I use this technique a lot. Michael :-)

The basic rule of COM says, In COM, once you "publish" an interface contract by shipping a component, the contract is immutable—it cannot be changed in any way. You can not add. You can not delete. You can not modify. But, when you open Microsoft Word 97/98 and Microsoft Word 2000 's .OLB files, you will see that for extending the interfaces, they have added methods to the old interfaces. For example, in MS Word 2000 they have added methods in Application interface, and all the other interfaces. Why So? I feel the right approach is to add new interface if you want to extend an interface. Can somebody tell me its' reason??
