Upload these VBA files to any workbook and start playing chess, today!
This can be great if you're playing chess via a shared workbook in the cloud or on a network drive. It's also pretty handy if you're playing chess via e-mail -- just copy+paste the board to your favorite e-mail client and send! Algebraic notation included for ease of communication.
Simply 'clone' or download these files to your computer and then upload them into any workbook from the VBA menu in Excel (you only need the 3 files -- the 2 "Spawn_form" files and the "chess_main" file.
To access the VBA menu in Excel, simply enter Alt + F11 while Excel is open. Then choose 'File' > 'Import File...' and choose 'chess_main.bas' > 'Open.' Repeat this for 'Spawn_form.frm' as well. The .frx file needs to be in the same directory (I think), but it probably already is if you downloaded / cloned this project, so no worries. It may not be necessary, I'm not really sure...
Once you've added the files above, simply double-click the "chess_macro" file from the VBA window and run "setup()" -- you can do this by simply clicking anywhere in the "Sub setup()" submodule and then choosing "Run" > "Run Sub/UserForm". Alternatively, just press the F5 button to run it. A new worksheet called "Chess!" will be created with all of the necessary buttons, logic, etc.
