My question is whether or not my Excel Macros that reference a homemade
DLL will need to be changed to work in Windows 2000?

Or if the DLL itself needs to change due to the switch to Windows 2000?

I have only used Win9x in the past where the DLL and the macros that
reference it work just fine.

The reason I cannot test it fully myself is because of the hardware my
DLL references is not currently on site. My DLL makes many simple calculations returns values based upon input, nothing out of the ordinary. It references one other DLL only passing and receiving integers back and forth.

I am trying to anticipate what I will need to do to be up and

Thanks in advance,
