I'm trying to write a subnet calculator for a small part of an assignment and it keeps screwing up and giving me the wrong values or errors so I need to have a look at a working one to see if I can spot the flaws.
It has to be in vbscript so the usual downloadable calculators or online calculators won't do the trick
Anyone able to suggest something?

Typed in vbscript subnet calculator and this came up: http://calculate.software.informer.com/download-calculate-subnet-mask-vbscript/
Hope that helps, not sure though.

Nah I found that one myself and its not what I needed.
Yeah that looks pretty much what I was trying to do, thanks, I clearly screwed up something because in one instance a binary octet started with a 2.
I think I might hardcode it for the demonstration, the effect will be much the same and considering I've had 6 weeks to individually do the work that was supposed to take 3 people 6 months, I reckon my lecturer will be pretty understanding about it.

NERD!
In a good way, of course. I've never gotten that into programming though.

Nor have I to be honest but I've been told I have a programmers brain (I should put it in the fridge to keep it fresh). I ended up writing 3000+ lines of code for my major networking project at college completely alone because noone else in the class cared about helping (well one did but he was doing the business side of the project whilst I did the tech side).
Now at uni I'm doing the same thing on a much tighter deadline with the only advantage being that I'm working on the same type of program so I can recycle the framework and some of the more stylish parts to cut down on the work a little.
I suppose its an example of Rapid Application Design...
