SysexHandler Files

This is complete rewrite of my "sx.exe" utility, which I had been using since the days of DOS. Eventually it became necessary to build a solid MIDI communication base for modern Windows operating systems.
There are a number of MIDI programs out there but I could not find a lean-and-mean sysex tool which just allows to save and restore sysex dump from/to MIDI devices.
The MIDI Sysex communictation in Windows is rather complex (to my mind) and I hope that I finally mastered it. (I still remember, back then, when I modified a "multi-IO card" for the use with MIDI. The communication engine programming was simple then, just consisting of a interrupt service routine and a circular buffer ...)
Anyway, I thought maybe someone else will find it useful and/or is interested in it. So here it is. There is no license paragraph in the source files; consider the code as public domain. There is not anything special anyway in it.
The application can be run in GUI or CLI mode. GUI mode is the default if cmdline parameters are given. You may call it from a text base shell (e.g. Windows cmd.exe). Following the GNU tradition "--help" gives a short cmdline help.
There is a basic HTML online help as well. It is intalled along with the application by the installer.
Recently I switched to the CodeBlocks development environment with MinGW. Previously I had been using MSVC 2.0 (I legally own a copy) and later the MinGW DevStudio by ParinyaSoft. They seem to be out of business so I had to switch. In the V1.1 tarball the old project files are still included.
For the installer I use the free "InnoSetup" from http://www.jrsoftware.org

I am be happy about any hints/ideas/discussions about the functionality, coding, and documentation.

Have fun!
