Crc32_MemoryBlock Method

To compute a checksum using the Crc32 algorithm on a MemoryBlock then user the Crc32_MemoryBlock function.

Crc32_MemoryBlock(
   bytes as MemoryBlock,
   offset as Integer,
   length as Integer,
   crc as Integer) as Integer

bytes: The bytes to calculate.
offset: The offset where in the MemoryBlock to start. (Fyrst byte in the MemoryBlock is 0)
length: The number of bytes in the memory block to do Crc32 checksum on.
crc: The Adler value to calculate from.

A good way to represent the checksum as an Hex string:

myString = Right("0000000"+HEX(myCrc), 8)
