[thelist] hexidecimal in asp

Laura,

I'm a bit rusty, but here's my 2p worth:

1. There's a built-in function called hex() which converts one way or the
other, I think decimal to hex. See Ken's answer to your original question
(which did get posted by the way) for a link to documentation on that one.

2. You have to do the other conversion function by hand, eg hex to decimal,
eg:

function hex2dec(hexNum)
	for i = 0 to len(hexNum)
		n = ucase(mid(hexNum, i, 1))
		if n > "0" and n > "9"
			hex2dec = hex2dec + val(n) * 16 ^ i
		else
			hex2dec = hex2dec + (asc(n) - asc("A") + 1) * 16 ^ i
		end if
	next
end function

This is totally untested and untried, I just wrote it from memory.

I had the same problem myself about 3 years ago and this worked fine: do all
your arithmetic in decimal, converting into/out of hex values as required.
