one of the simplest COM objects. The component class is called Atlcomserver, and the implementation interface is called Iatlcomserver, and the library name ATLServer. Add a property name and implement the Get/set function. The IDL looks like the following: Import "Oaidl.idl"; Import "Ocidl.idl"; [ Object UUID (77506E08-D9FB-4F45-85E0-376F5187AF21), Dual Nonextensible, helpstring ("Iatlcomserver Interface"), Pointer_default (Unique) ] Interface iatlcomserver:idispatch{ [Propget, ID (1), helps

need to register any COM class or even call a mandatory coinitialize function. The Active Template Library (ATL) ccomptr class processes a small portion of the remaining COM. However, you do need to pay attention to thread security because xmllite is NOT thread-safe due to the performance in the single-thread solution. In the following example, I use the com_verify macro to clearly identify where the method returns the hresult to be checked. You can

user does not know the existence of the new interface imathe2, and he still uses the old interface imathe; while the new user can discard imathe and directly use the new interface function of imathe2. Look, how smooth the upgrade is! Iii. Implementation3-1,First, Use ATL to implement a COM component of the custom (M m) interface imathe, and complete the add () integer addition function in the interface.Note !!!It must be a custom interface (dual interface will be introduced later ).
