Maury,
As Tom says, an XLL is compiled, so forget about seeing the code.
I'm not sure how different an XLL is from a standard DLL, but with the only
XLL that I have on my system (ANALYS32.xll), calls to it seem routed through
XLCALL32.DLL's "Excel4V" function. So, assuming the actual call, arguments
and return type etc are correct (which I am not), this will not work:
Private Declare Function XLLFunc1 Lib "C:\ANALYS32.XLL" Alias "bin2dec"
(BinStr As String) As Long

There probably are ways of using the XLL directly, but not sure how straight
forward in VB:

However, it does seem a rewrite would be easier if you understand the
concepts of the functions in the XLL and create an ActiveX DLL that's native
to VB or a standard DLL with some extra work.

Well it's not EXACTLY what I need, but it will likely help me get there.
Thanks!
