ASP.NET and mapscript - unable to load DLL

[Mike Boos]

I tried moving the dlls to the system32 directory, but that doesn't have 
any effect (am I missing any other dependencies?)

Unfortunately, I'm kind of stuck with ASP.NET, as that's what the rest 
of the site relies upon. I'm trying to improve the present setup which 
involves sending a request to a C++ CGI program which writes a map file 
to the hard disk and forwards the request to mapserv.exe. If you'd ask 
me, that's a bit of a kluge, and without Mapscript, all I could do to 
improve on that would be to take out the C++ program and have the map 
file generated from within the ASP.NET program itself. Can you think of 
a better way to accomplish the same task?
