Hallo *, Here's the problem: unsigned int ui = 4294967295; //2^16-1 unsigned long long uL; //8-byte variable uL = ui << 16; The outcome of this operation is 4294901760, meaning that 16 bits were shifted to "nowhere". Seems to me that bitwise shift operator does not work over 32-bit limit. Is there a simple work around this problem? BR, -- Krzysztof Wisniowski | Siemens Sp. z o.o.
