How to move 2 DWORD to __int64?

[zehdopulo]

Hi. I have a FILETIME struct that contains 2 DWORD (lowtime and hightime) and, for comparations, I need to move this values to __int64. How I do this?
Thanks

Value|=hightime;
Value<<=32;
Value|=lowtime;

unsigned _int64 x=time.dwHighDateTime;
x<<=32;
x|=time.dwLowDateTime;
