c++ - Use COM Object from DLL without register

Question

Is it possible to use COM Object from DLL without register in C++ not managed code?

Answer 1

Yes, if it does not rely internally on other registered objects.

1. You LoadLibrary the DLL
2. You GetProcAddress its DllGetClassObject
3. You call DllGetClassObject to obtain IClassFactory pointer for CLSID of interest
4. You are good to go with IClassFactory::CreateInstance and instantiate the coclass
