Question

I get the following error:

Error 1 error C3867: ‘CHelloproxy::Hello’: function call missing argument list; use ‘&CHelloproxy::Hello’ to create a pointer to member c:\users\uma\documents\visual studio 2008\projects\nproject\nproject\Helloproxy.h 24 Nproject

HRESULT hr = CoCreateInstance(
        __uuidof(Hello),            // Request Hello object
        NULL,                   // This is not an aggregate
        CLSCTX_INPROC_SERVER,   // COM object in client’s address space
        __uuidof(IHello),             // Request IHello interface pointer
        (void **) &pIHello);

Answer 1

The Compiler docs say:
“You tried to take the address of a member function without qualifying the member function with its class name and the address-of operator.”

Are you passing the name of a member function as a parameter accidentally?
