So I have the following code which works nicely:
CMyClass& CMyClass::operator=(DWORD rhs)
...
CMyClass exc;
exc = GetLastError();
And it does everything I expect it to (call the stuff inside the =
operator.) I was wondering how to get it so that I can instead write it like the following:
CMyClass exc = GetLastError();
I tried using the above and it doesn't call the =
operator functionality, instead just leaving me with a class where just the default constructor has been called.
Thanks
A constructor is required.
CMyClass(DWORD rhs)
Or explicit
explicit CMyClass(DWORD rhs)
Be warned , the implicit constructor allows this to compile;
CMyClass exc = GetLastError();
But it also participates in compiler generated implicit constructions and conversions. It is generally better to have to be explicit and write;
CMyClass exc ( GetLastError() );
