I have created a DLL from an external program. I keep the
dll in the same directory as the xls file. On my machine,
when I run the VB macro Excel finds it and does the
business. I run ME and Office 2000 Standard.
When I give this to a NT machine running Excel 2000, It
will not work and says it cannot find the DLL.

Is there some way to tell Excel in all its versions where
to expect dlls? Load it somehow?
