something is really making my angry...

a FILETIME is a struct consisting of two dwords, so it is 8 Bytes, the
same memory usage as a 64Bit-Value.

but i cant do a...

FILETIME FT = 0;

for example.

So i'd like to do my own overloading that lets me assign and compare
any value in the range 0 - 0xffffffffffffffff to a FILETIME. I'd like
to have the following possible:

FT = 0xabcdef;
int i = FT;

foo(17) when foo is defined as ... foo (FILETIME ft) {...}

so .. can i do this somehow?

You could try something like

class CFileTime: public FILETIME
{
public:
    CFileTime(__int64 t)
    {
        dwLowDateTime = (DWORD) t;
        dwHighDateTime = (DWORD)(t >> 32);
    }
    operator __int64() const
    {
        return (__int64)(dwHightDateTime << 32) | dwLowDateTime;
    }
};

and use CFileTime instead of FILETIME. Perhaps you want to define some other
operations, too, but basically that should do.
