Compiler Error C3463

  • Artikel

'type': type not allowed in attribute 'implements'

An invalid type was passed to the implements attribute. For example, you can pass an interface to implements, but you cannot pass a pointer to an interface.

Example

The following sample generates C3463.

// C3463.cpp
// compile with: /c
#include <windows.h>
[object, uuid("00000000-0000-0000-0000-000000000001")]
__interface X {};

typedef X* PX;

[ coclass, uuid("00000000-0000-0000-0000-000000000002"), implements(interfaces=PX) ]   // C3463
// try the following line instead
// [ coclass, uuid("00000000-0000-0000-0000-000000000002"), implements(interfaces=X) ]
class CMyClass : public X {};
