Hi Christof:
Thank you very much!
I use the third type ,isapi instantiate a com server.But I think the asp.net is the same as asp
asp.net deal with aspx ,ascx and so on through "C:\WINNT\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll"
the third way is a best way to make a vfp web tools? or the 4th way?
