So far, I've had to just give up and use fopen and fprintf to write to my text logfile, but I know that a real man would have used wxFile. The problem is, I just can't figure out how to make my wxFile a global object in my application (maybe after I've had more sleep; I guess I'm once again forgetting to consider objects as objects) so that I can open a file, leave it open, and add to it in different subroutines. So, in the meantime, here are my favorite links for wxFile:
