Maury Markowitz a écrit :

I have an ancient XLL plugin for XL that we use, and since the time we
purchased it we've moved most of our code to VB. I'd like to move this over
as well, but I'm not sure how to do it. Is there some way to load an XLL into
VB? And if so, how do we call it? The XLL is currently called use
"Application.Run", but I'm not entirely sure what this command does.
