gosh, thanks for the replies..., i thought it wouldn't be that much...

now, if 2.3.1.7 and the last digit (7) is bulid digit. Does it mean i have pressed F7 at VC++ IDE 7 Times? So if it does, how can i automatically increase the number in my .rc files version info? And what about the other digit? Are there no sucha automated tools to do versioning?

Many thanks for the replies...
