if they are identical. I have the ability to remember
information about the files, so it would be handy to keep

Short of writing the checksumming code myself, is there a
way of generating checksums on Windows files? (Appearances
to the contrary notwithstanding, this is not actually a
yes/no question; please do not respond unless you can
actually point me at something useful. :-)
I'm using Borland C++ on Win32.
Extra credit (but no extra points :-): It'd be nice to be
able to generate the checksums on buffers in memory as well.

zlib is a free compression library (a DLL) on which the popular gzip utility is built. In this article, we'll see how to use the zlib functions to compress and decompress data in memory; that is, without needing to use a temporary file. We'll be c…
With most software applications trying to cater to multiple user needs nowadays, the focus is to make them as configurable as possible. For e.g., when creating Silverlight applications which will connect to WCF services, the service end point usuall…
