Checksum calculation

For safety reasons I have to calculate a checksum of a LabView .vi
respective .exe file. How can I calculate a checksum of a file in LabView?

Hi Mike,

send your email adress to buero@hersacher.de and I can send you some checksum calculation VIs for CRC checksums.

Bottom line, a file is a file is a file. To calculate a CRC simply use one of the existing File IO examples to read the VI as so many data bytes and calculate the CRC of the file contents.

The attached library has functions for doing 32-, 16- and 8-bit CRCs as well as a good old fashioned checksum.
