thats an aweful load of work for something so small :)
a few points: - 1. WinPaintChars() -> os 3.5+ only if i recall right
- 2. why not just use pilrc to do all this?
VERSION "..." <-- this is what you have now
change it to this:
DATA "tver" ID 0 "time.stamp"
add time.stamp as a dependancy for the .prc, and, when done
building, remove the time.stamp file. add the following:
time.stamp:
date +%y%m%d-%H%M%S > time.stamp
done..
now, when someone goes to the os "version" page, it will show the date.
you could extend this idea to do whatever you want, even store it as
a string in the .rcp file for reading (instead of using the .h file)
oh.. the joy of makefiles :)
