This is a question I have been wondering about for a long time. Is there any good way of recording a build number in a project (ie the amount of times it has been compiled). The only way I could think of is to make a macro that updates a constant and then compiles the program. I am using VC++6 if you have any compiler specific recommendations. If you are unsure of what I am going on about, I mean like the Revision number in VB when you have checked Auto Increment. Thanks in advance.
