A HANDLE is a long pointer. In QB64, our equivalent is an OFFSET. A long pointer is 4 bytes in 32 bit and 8 in 64. In QB64, an OFFSET is 4 bytes in 32 bit and 8 in 64. It's our closest approximation. As for the class name with the "at AND &HFFFF~&", I'm not sure where they would have gotten that value for their class. Very odd. I've not seen something like that before. If I were you, I'd instead use the actual name of the class and keep the declaration with OFFSET. It looks like you defined it as "QB64pe". So just pass it as _OFFSET(ClassName) in your call there rather than that weird "at AND &HFFFF~&".
