I wasn't sure where to put this, but this one made the most sense.
I've written a 16 bit app in C and I'm going to use it as a sort of basic login program (not incredibly secure but enough to keep out the idiots who will screw something up). The method I'm using I found on some other forum site, experts exchange or something like that, basically I rename my program to command.com and the real command.com to com.com or something. My program will execute (this is all on win9x mind you), then call com.com to run. But I've been told there's some complicated stuff I have to do, so can anyone tell me what's up? What do I have to do?
