Compiler Error C2647

'operator': cannot dereference a 'type1' on a 'type2'

Remarks

The left operand of a pointer-to-member operator (->* or .*) cannot be implicitly converted to a type related to the right operator.

Example

The following example generates C2647:

// C2647.cpp
class C {};
class D {};

int main() {
   D d, *pd;
   C c, *pc = 0;
   int C::*pmc = 0;
   pd->*pmc = 0;   // C2647
   d.*pmc = 0;   // C2647

   // OK
   pc->*pmc = 0;
   c.*pmc = 0;
}
