IP Address conversion

This took me way too long to figure out. Converts IP addresses from decimal notation to quad dotted form. In ASP.

Function MyHex(ByVal Number)
Dim Sign
Const HexChars = "0123456789ABCDEF"
Sign = Sgn(Number)
Number = Fix(Abs(CDbl(number)))
If Number = 0 Then
MyHex = "0"
Exit Function
End If
While Number > 0
MyHex = Mid(HexChars, 1 + (Number - 16 * Fix(Number / 16)), 1) & MyHex
Number = Fix(Number/16)
WEnd
If Sign = -1 Then MyHex = "-" & MyHex
End Function

Function decToQuad(Byval dec)

HexVal = MyHex(dec)
ip = ""

for i = 0 to 3
temp = Left(HexVal,2)
ip = ip & Eval("&H" & temp) & "."
Hexval = Right(Hexval, Len(Hexval) - 2)
next
decToQuad = Left(ip, Len(ip) - 1)
end function
