To anyone referring to this in the future, my problem was that I was reading the file in binary mode, and FM calculates the file based upon reading it in ascii mode.  Thanks for the help, Andy!

I still can't get a CRC that matches what FM is reporting.  Is FM taking the CRC of the hex file, the bin file output, or some strange combination or subset of one of the files?  I've tried my test app on both the hex and bin, to no luck.

Thanks for the help.  I really appreciate it.

I appreciate the quick reply.  For all my efforts, though, I cannot get a CRC32 algorithm to duplicate the checksum that FM reports.  Is there any way I could either get the source to the CRC algo it's using, or is there any way to retrieve the CRC of a given file with the FM api?

Thanks!

Hi there.  We just started using Flash Magic for loading our new product.  For production purposes, we would like to be able to include the CRC viewed in the "more info" screen independent of the file, generated programmatically.  Simply running the hex file through a standard CRC32 generator does not result in a CRC that matches the one in Flash Magic.  Is the polynomial that FM uses different than the "standard" poly that WinZip et al use?

Thanks for any help you can offer!
