Here are a couple of Windows programs I've written.

They are zip files, so they have to be down-loaded to your system and expanded by running WinZip (or a similar program) on them.
If you don't have WinZip yet, you can get it from http://www.tucows.com . After giving your location, click on Download Library, then on FTP and Archie under Network Tools.
If double-clicking on the files doesn't down-load it, try using a right click and 'Save Link/Target As'.
Each file expands into a .EXE program file and a .HLP help file

This is written in Visual C++ with MFC. See Help | Tutorial for a blow-by-blow walk-through and Help | About for a brief summary.

This is a version of Tetris with lots of options. It was my first windows program, written in Borland C++ with OWL.
Warning: If you change the format of the 'well' and play for twenty times or so, the program will crash, presumably because of memory leaks.
This was the last part of the game I worked on, hence it didn't get as much testing as the other parts, that's why it's a pre-release version.

Although the help file was written in ASCII, it has lots of information about the game, including screen images. It will even tell you something about streaming a collection of objects in Borland OWL!
